WMG: Yu-Gi-Oh! ARC-V

Beware of spoilers! Many Wild Mass Guessings contain revealed spoilers for future episodes!

Sora is a time traveler from the time of Yu-Gi-Oh! GX
Well, he did say that, where he comes from, Fusion Summons are common. And he was being secretive about what just that is.
  • I like this theory, let's expand it a little. Sora was a student in Academy, he is from Obelisk Blue (his jacket is part of uniform, which was slightly altered with time). He is also an illegitimate son of Sho (because... hair). He also was named Sora in honor of victory over satellite SORA what almost destroyed Earth.
  • Unlikely. Sora knows a lot about Synchro and Xyz summon. Those way of summoning didn't exist in GX times.
  • Even less likely now, considering he's (probably) from Heartland City.
  • He's presumably not from Heartland, since it is a city of Xyz Duelists; he merely targeted Heartland because of that.
  • Partially Jossed. More like Dimension Traveler, but Duel Academia is shown in a recent episode as the home of Academia, the ruthless invaders who destroyed Yuto and Kurosaki's hometown Heartland City. And they're explicitly said to have trained students to be sociopathic "Duel Soldiers".

Pendulum Monsters replicate by turning other Duelists' monsters into Pendulum Monsters
Nobody knows exactly what Pendulum Monsters are or how they work, aside from possibly Yuya. We saw in episode 3 and 4 that other people are also able to use Pendulum Summoning, so it's not restricted to the Pendulum. Who's to say that Pendulum Monsters don't turn random monsters in their user's deck into other Pendulum Cards to make the entire thing a bit more balanced?
  • If so, then Sawatari may now have Pendulum monsters of his own in his deck, if they got "infected" by Stargazer & Timegazer Magician.
  • Considering he changed decks to Monarchs, I'd say no on that.
  • Jossed. They're either pulled out of thin air or manufactured, just like any other card.

The Mysterious Duelist/Yuto from Episode 7 is...
  • ...either Yuya's long lost brother/ half brother or an alternate-dimensional Yuya
    • I'd like to think they wouldn't do a Z-One thing again
      • It should be noted that Z-One wasn't actually a future Yusei. It was a completely different person that made himself look like Yusei.
      • What I meant was I hope they don't do something like that again, seeing as no one liked that twist as oppose to 'evil future Yusei'
  • ...a manifestation from Yuzu's subconscious that has taken a life of its own. She kept having intense heart pounding reactions to him, and her bracelet glowed around him, there's definitely some sort of connection between her and him.
  • ...Yuya and Yuzu's son from a ruined future. Hence why he resembles Yuya and also is protective of Yuzu.
    • And Sora is from the future to.
    • And Ruri isn't Yuto's girlfriend; she's his sister.
      • Actually, Ruri is Kurosaki's sister.
    • Confirmed about the ruined part, "future" is unclear.
    • Josseled that he is their son.
  • Someone who has watched the entirety of the other four Yu-Gi-Oh! series. His Deck has at least 1 Mystical Space Typhoon, which on it's own would win practically every important Duel in the entire Franchise by killing the Heel's primary Spell/Trap card, ruining the quote-unquote "unbeatable" combos the baddies rely on.
    • He also realizes (unlike Sawatari's minions) that Xyz Summoning is not some kind of Dangerous Forbidden Technique meant only for the highest level duelists, but something anyone can figure out relatively quickly, and should use if it fits their deck.
  • Female, and attracted to both Yuya and Yuzu.
    • That.....would be a bit hard to pull off. I'd give them props if they did....but somehow I don't think any gender shocks are in the future.
    • No, no, dude, this is definitely gonna happen.
      • Everyone, I have some bad news... As you all know, in the years note  that Arc-V has been airing- YEARS! That Arc-V has been airing, the exact identity and gender of the Dark Duelist has been a mystery. It is a mystery no more, and I am truly saddened to reveal to you all that... this theory has been Jossed... I know that this is troubling news, but we must simply... 'breaks down crying'...
  • ...planning the downfall of LDS. He took advantage of his resemblance to Yuya, who he saw on TV, and specifically targeted Sawatari due to his father being a high-ranking official in order to spark the war between You Show and LDS, confident that You Shou, especially Yuya, would win, possibly destroying the reputation of LDS. His motive is to punish LDS for keeping the strongest cards to themselves and treating them as only good enough for the elite. His ace's name hints to this (Dark Rebellion Xyz Dragon), as does one translation of its summon chant containing the phrase "rebelling against the power of stupidity" (referring to LDS's overconfident elite).
  • An alternate version of Yuya that came from the pendulum he wears. Something happened to Yuzu in another timeline and that along with his daddy issues drove him to being more cynical. His Dark Rebellion dragon is an Xyz version of Odd-eyes dragon.
    • The 'alternate universe' idea seems to be getting more credence, as we've seen a ruined timeline where Yuto (Dark Duelist) was fighting a White Duelist on a D-Wheel, and Kurosaki (the second guy) was there too. They also mentioned a 'Ruri' and she seems missing. So Yuto is alt-Yuya, Ruri is alt-Yuzu (which is why he is caring about her) and... we have no idea about Kurosaki.
  • A cynical and heartbroken future Yuya, who witnessed Yuzu's death at the hands of the Leo Corporation. He then tore up his Pendulum and Entermate cards, broke his necklace, and disowned his father, blaming them on the grounds that if he had never Pendulum summoned, Leo would have never come after him, thus avoiding Yuzu's death. He builds a new deck and enters a strained homosexual relationship with Shun Kurosaki in order to travel to the past to try to save Yuzu. However, Kurosaki dies, and Yuya will find out that You Already Changed The Past, leading to him Jumping Off the Slippery Slope, so he goes back even further to orchestrate the Zero Reverse in Z-One's timeline, prompting Z-One, Antimony, Paradox, and Aporia to also go back in time, the four of which are stopped by Yusei. He travels back even further by thousands of years, losing his humanity and manifesting as Zorc Necrophades. After being defeated by Atem, he reincarnates himself as both Darkness and the Light of Destruction. Being defeated once again, he recollects his fragments and travels back to the creation of the universe, gathering the chaos ejected from the Astral World as they attempt to Rank-Up, and using its power to create the Barian World, claiming himself as its god, Don Thousand.
    • Alternatively, he goes to the Astral World and attempts to stage a bloody uprising using the power of Chaos, but is defeated by Eliphas and Astral. The Astral World, now paranoid because of Yuya/Don Thousand's abuse of Chaos, decides to banish it entirely from their realm, making him the sole reason for the segregation of the Astral and Barian Worlds, and the strife between their denizens.
    • In light of the possible connection of Marco's kidnapping with the Dark Duelist, this Troper has realized that Marco was the one specifically responsible for Yuzu's death, out of revenge for his kidnapping, which ties in to how Yuya Already Changed The Past.
    • If you're still following this particular WMG, you may now be wondering "How could Marco kill Yuzu if his soul was sealed into a card?" The answer is straightforward: ... He got better.
    • Belligerent Sexual Tension between Yuto/Kurosaki confirmed!
  • ...a split personality of Yuya's, one where his pessimism overrides his joy, that somehow exists separately from Yuya. As both are technically Yuya, they share certain qualities, one of which being their care for Yuzu. The difference is, while Yuya thinks Yuzu can handle herself, the Dark Duelist is not willing to take that chance and puts himself in her place on the battlefield. The Dark Duelist's Perpetual Frowner persona represents an inner doubt of Yuya's that, regardless of what he tries, even his own smile may vanish forever.
  • Like ZONE for Yuya. You know how ZONE traveled back in time to prevent his own dark future from happening, and he underwent plastic surgery to look like Yusei in order to drive him insane?
    • I... don't think they'll reuse a plot-line...
  • Not A Villain. Instead, he simply wants to start a band with Yuya/Yuma/Yusei/Judai/Yugi/Yami, and wants every character, major and minor, from the past four series as his Roadies. Personally, I think that Aki/Anna/Astral/Asuka/Otogi would make especially awesome Roadies... The instrument that the D-D wants to play? The ukulele.
  • Actually Yuya himself from the present time. Either in the form of a Superpowered Dark Is Not Evil Side or that Yuya is just Obfuscating Stupidity. Before his father disappeared (thanks to the Leo Corporation), he gave Yuya another deck and instructions to Take Up My Sword.
  • A wandering shipper trying to make sure Yuya and and Yuzu have the sex.
    • Dude, that's even less likely than my Ukulele thing...
    • His ploy is that by looking like Yuya, he deliberately fools her into thinking he is Yuya, as well as conveniently timing his exits with his entrances. Thus, he will make Yuya as badass as possible while demonstrating protectiveness towards Yuzu, thus increasing her attraction towards him.
    • Furthermore, the D-Wheeler in his flashback shipped Yuzu with Masumi, and the duel between the Dark Duelist and him was actually Ship-to-Ship Combat.
  • A descendant of Mizael. A dragon tamer with supernatural powers and a competent Xyz duelist. Dark Rebellion Xyz Dragon has a very similar color scheme to No. 107: Galaxy-Eyes Tachyon Dragon and uses the same roar sound effect. Additionally, he has a motorcycle riding opponent clad in white, who wields what appears to be a Light Dragon monster that uses the same roar sound effect as Galaxy-Eyes Photon Dragon.
  • Yuzu's biological brother, who has come to look for her, and her actual name is Ruri. However, as Maiami City is better than his home, he decides to stay and protect her from afar.
  • A reincarnation of Yuya, sent back in time through the Pendulum to get what he needs to save the world and pass on. Basically, Yami, from the opposite side of the timeline.
  • Droite and Kaito's son, from ZEXAL. I mean, he has the eyes and hair, even the damn upright hairstyle.
  • A person from the real world who plays the card game and managed to somehow enter the TV show in order to make the show match the actual card game more. That MST speaks for itself.

Because she gave off a serious Ragyo Kiryuin vibe in episode 8.

Yuzu will defect over to LDS and pull a Face-Heel Turn due to not being able to fully trust Yuya thanks to the Dark Duelist.
  • It's very unlikely, but you never know.

Yuzu is a Deuteragonist
We all know that all the Yu-Gi-Oh protagonists have the "Yu" Syllable in their names. By this logic, ARC-V is the first Yugioh series to have both a male and female protagonist; Yuya and Yuzu.
  • It should be noted that the "Yu" in Yuya (遊) and the "Yu" in Yuzu (柚) are actually two different Japanese characters, and though they sound similar in English, they have different meanings in Japanese.
  • She at least wants to be; she faced down Sawatari with every intention of beating him, and is similarly motivated to beat LDS. Time will tell how much she will get to duel, though.
  • Alternatively, she'll just be the other major duelist besides Yuya; essentially the Jounouchi to his Yugi.
  • In episode 8, Himika states the You Show vs. LDS duels will be 2 out of 3. Episode 9 has Yuya victorious. Episode 10's preview states that Yuzu misplays. Episode 11 states that Gongenzaka duels. In other words, Yuzu is thrust out of her duel and loses her next, after just one victory. At worst, this may be premature Chickification the likes of which happened to Aki in 5D's.
  • Her bracelet glowing the way it did in Episode 7 shows that it seems to have some kind of power, though what it is hasn't been explained - just like most of the previous protagonists having some kind of magical accessory, though not in the form of a pendant or necklace in her case.
    • Per ep. 18, it seems to force-teleport Yuto/Dark Duelist around. In 18, he was teleported to where the other Dark Duelist, Kurosaki, was dueling Tio from LDS. WHY it teleports him is another matter entirely.

Someone will use Ritual Monsters against LDS
It's the only summon type, bar Pendulum, the LDS do not apparently have a monopoly on. A Ritual Monster (Elemental Mistress doriado) also appeared on an advertisement, the only of the special summon type monsters to do so. Plus, Sawatari did throw Hungry Burger at Yuya as a 'trash common'.
  • An upcoming foe Yuya is to duel will be using them, though her allegiance is of yet unknown.
    • Mieru has now made her appearance, and has joined the protagonists.

Reiji is a descendant of Seto Kaiba.
It would certainly explain their resemblance.
  • Doubtful; I think he'll use the Kaiba name in that case, just for the connotations.
    • But its possible his name may have changed as time goes on.
  • Lampshaded in the Abridged Series though it was proven wrong there.

Sora is connected to the Dark Duelist/Yuto
  • Doubtful, considering they met face-to-face in episode 15 but Sora didn't recognize him at all, and vice versa.
  • They still might be somehow related. Sora mentions that the Dark Duelist isn't "from around here" and he retorts the same about Sora. Where exactly they are both from might be the same, explaining their Genere Savviness.
    • Confirmed. Sora is part of the enemy Fusion faction Yuto has been fighting against.

There will be a series of dragons named after the various Summons
We already have Odd-Eyes Pendulum Dragon and Dark Rebellion Xyz Dragon.
  • Considering that in a flashback, the Dark Duelist faced a white dragon wielded by an apparent D-Wheeler, we might have a X Y Synchro Dragon, considering the connection between Synchro monsters and D-Wheels. As he summons it, there is the same beam of light from which Synchro monsters emerge present, albeit without the green rings.
    • Add to that Clear Wing Synchro Dragon, the above monster.

Yuya will eventually duel his father, who will use the Odd-Eyes archetype. His ace monster is "Odd-Eyes Magician", which is the monster seen with him in the intro.
It's been heavily implied that Odd-Eyes Dragon was a gift from Yusho, and for once, the protagonist's father both duels and has a different deck from the protagonist. As well, the real-life effects of Stargazer Magician and Timegazer Magician specify any "Odd-Eyes" monster and not just Odd-Eyes Pendulum Dragon, hinting at the existence of more Odd-Eyes monsters in the future. Yuya will probably go on a journey to find his father later in the series, who somehow got abducted by the Big Bad, and they will duel.
  • OR Yusho is the true Big Bad, and they will duel to end the series!
  • It'll probably be the very last duel, after the Big Bad has been defeated, similar to Yugi vs. Atem, Judai vs. Atem, Yusei vs. Jack, Yuma vs. Astral.

How Leo Duel School managed to get a monopoly on the Extra Deck:
First, these kinds of cards are rare to begin with, so it wouldn't be as hard as in real life. Then, if someone gets one, they get challenged to a duel. If they win, they get automatically enrolled into LDS, since they are good enough to qualify. If not, the card gets taken from them. If they are found before being played, then the holder may sell it to LDS; otherwise, it gets stolen. All of this is managed by a dedicated enforcement squad.
  • Alternatively, LDS has managed to keep hidden the fact that duelists can pull brand new cards right out of their asses. Yaiba's "training sessions" with Gongenzaka was probably just informing him of that fact, and a few practice duels to get accustomed to the strategies for it. Same with Sora and Yuzu.

The show's setting up characters to represent the 4 summoning techniques.
Yuya obviously represents Pendulum Summoning. Sora represents Fusion, the Dark Duelist Xyz, and possibly Sawatari or Reiji (though the latter might get Pendulum, because he's The Rival) could represent Synchro. All four would have an important role because of their summons.
  • Do Ritual Monsters fit in here somehow?
    • Mieru Hochun.
  • The series does have a few sets of this: (Yuuya, Yuto, Yugo, Yuuri), (Yuzu, Serena, Rin, Ruuri) and (LDS trio, Reiji). However, it does seem these sets are pure as each of the pendulum users in each set can do at least one other summoning.

Reiji will create his own Pendulum cards
Word of God has stated that Reiji is highly intelligent, and he has shown great interest in Pendulum summoning. The manga oneshot shows him using "DD" cards, a new Pendulum archetype. The episode 13 preview states that during Yuya and Reiji's duel, "Everyone, including Yuya, can't believe their eyes at what they see!" Looking back to Yu-Gi-Oh! ZEXAL, episode 13 was wherein Yuma gets curb stomped by Kaito... and we may see a parallel here.
  • Confirmed, though they do malfunction due to changing level scales.
  • And the duel gets cancelled, too, for the benefit of the protagonist. Though in this case, Reiji's victory is only implied by his set card, rather than shown as imminent with Kaito's attack.
  • Later fully confirmed: he created fully working Pendulum Monsters for Sawatari.
Evilswarm Monsters will be used by a future adversary.
Someone might get corrupted or the person using the Evilswarm will be connected to the Big Bad of the season. Also, three of the Duel Terminal archetypes note  are used by characters in the series.
Ms. Akaba and Shuzuo will eventually fall in love

Rather than giving us shippers a middle finger about character relationships, Yuya and Yuzu will become a couple before the series is over

The series takes place in an alternate world than the one in the previous canon, and Sora and The Dark Duelist/Yuto are both from the world of the previous series' timelines.
This would explain why they both have access to summoning types that supposedly LDS has a monopoly on, and there's been no word on whether or not Maiami City is the future version of/related to any of the previous cities.

Sophia, Goddess of Rebirth will appear in the series
This series already has all 4 summoning types (Sophia requires a Ritual, Fusion, Synchro and Xyz Monster as Tribute to Special Summon) required to summon her card. All 4 have been proven to at least, exist in this series.

There will be a Syncho user who is a descendant of Yusei and Aki.
This series has done things a little differently from previous series. I'm hoping a significant appearance by previous protagonists or their descendants is yet another of those things they are doing different.

Yuzu's bracelet will...
  • Grant her Pendulum Monsters.
    • Seeing how it glowed and when Yuya's Pendant glowed, it granted him Pendulum Monsters. It will grant her the Monsters when she has a realization about Yuya and The Dark Duelist.
  • Grant her Xyz Monsters.
    • Alternatively, the bracelet resembles the Overlay Units of an Xyz Monster. So instead of Pendulum, it will grant her Xyz Monsters.
    • (going of of this and another theory) It was SUPPOSED too until the time traveling Sora interfered and made her want to Fusion summon, thus removing some future he didn't want to happen.
  • Give her a MASSIVE lady-crush on Aki's tight ass.
  • Sora did give her Polymerization, but anything else remains to be seen
  • It does seem to be related to the Dark Duelist. Because it glows a second time in his presence, allowing him to escape from Masumi and Sora.
    • It force-teleports him when it glows (note how he was just GONE when it happened the first time, and in 18 it happens and then he's like 'Uh, where am I?')

Masumi will...
  • Make a Heel-Face Turn and join You Show as a protagonist.
    • End up being plot relevant in some way.
  • Somewhat confirmed in that she decided to find Professor Marco when he went missing. Which will likely put her into conflict with the Dark Duelist.
    • Confirmed in that she did interact briefly with the Dark Duelist, though he was able to escape.
    • Somewhat more confirmed thanks to her duels with Kurosaki and Yuzu.

The Dark Duelist/Yuto had something to do with whatever happened off-screen that required Reiji to cancel his duel with Yuya.
  • Confirmed. The Dark Duelist attacked Fusion Professor, Marco.
    • Not quite confirmed yet. It might have been Shun Kurosaki, a new character who is said to know the Dark Duelist and to have attacked LDS.
    • A flashback shows the Dark Duelist and Kurosaki apparently working together, and Kurosaki is shown to be able to seal souls into cards, which is shown to the fate of Marco as well as one of the main investigators in Marco's disappearance. Additionally, the claw marks Kurosaki's monster makes are identical to the ones that were at the site of Marco's disappearance. So while the Dark Duelist is not directly responsible for the attack, he's involved in some way.
  • Jossed-ish. It was in fact Kurosaki who attacked Marco.

Yuzu will get her duel with Sawatari in the future.

Reiji's true ace will be an Expy of Blue-Eyes White Dragon
If it fits in with his DD/DDD archetype, it might even be a DDDD (Different Dimension Daemon Dragon).
  • All of his DDD monsters except for the last one are named after famous historical conquerors. Maybe the last one will be named Kaiba?
  • Reiji's ace and ARC-V's Blue-Eyes White Dragon Expy seems to be Hell Armageddon. He even has three copies of it, just like Kaiba owned three Blue-Eyes.
  • He might pull a Manjoume and switch up his aces. Arc-V may well keep in line with the recurrence of aristocratic rivals using 3000 ATK dragons. Alternatively, the Dark Duelist may upgrade/rank up(!?) Dark Rebellion into a form that has 3000 original ATK.
  • Of the four DDD monsters, Hell Armageddon is the odd one out. It's the only one not named after a historical figure, the only one not associated with a classical element, and the only one without a humanoid appearance. It also has a purely defensive effect. Reiji will probably replace it when Leo Corp improves it's ability to manufacture Pendulum Monsters.

Yuya runs 2 or 3 copies of Timegazer, Stargazer, and Odd-Eyes
  • It may never show up, all 3 of them at once, but there is no way he's lucky enough to continually draw those same three every duel. It makes sense with Yusei always getting Stardust or Yuma always getting Utopia, but those are extra deck monsters that don't require specific monsters.
    • all of Yuya's Pendulum monsters are unique magically altered versions of non-Pendulum monsters Yuya already owned, he hasn't summoned non-Pendulum versions of any of those three since they were made Pendulum monster (suggesting that all his copies of each were changed at that time ), and he acted like he couldn't Pendulum summon after Timegazer and Stargazer were stolen by Sawatari (meaning he didn't have any Pendulum monsters other than one copy each of those two and Odd-Eyes) all of that adds up to Yuya only owning one of each and just being that lucky (unless he bought two new copies of each off-screen after his duel with Sawatari and they immediately became Pendulum monsters.)
  • That makes sense. As said previously, When he dueled Sawatari, Odd-Eyes, Stargazer & Timegazer were the only three Pendulum Monsters he had. Then, during his next duel, some of his Entermate Monsters were Pendulum Monsters without any explaination; that probably means he now knows how to make at least some of his monsters Pendulum now. And it would be nice if we had a protagonist that is good enough at deck building to have multiple copies of a card they need.
  • For what it's worth, when Yuya spreads out his cards in episode 16, he only had one copy of each. It's common deck-building practice to place duplicate cards atop each other or otherwise adjacent, and the fact he did not do this suggests that he may indeed only have one of each.
Sawatari will get Pendulum/Xyz/Synchro/Etc Monsters
He has that necklace of his, although it hasn't glowed like Yuya's pendulum or Yuzu's bracelet. He'll probably get something in relation to what Yuzu gets, if anything. (I'm still considering the chance that her bracelet glowed because it detected the Dark Duelis, or some shit like that.)
  • He may get Ritual Monsters. He has previously shown a preference towards main deck monsters, including having a Monarch deck (where all of their new support has the drawback of not using your extra deck).
  • Confirmed, he gets Pendulum monsters. Though his necklace had nothing to do with it, as far as we can tell.

The Dark Duelist/Yuto, will, at some point, get cornered in a duel where nobody thinks he can win...
  • ... Only to topdeck Mystical Space Typhoon and use it to destroy a Spell/Trap (or even Pendulum!) card that was integral to his opponent's combo, allowing him to secure victory.
    • Yuto and Michio both enter the tournament. They face each other. Yuto uses MST on Food Cemetery. Michio cries, his strategy totally ruined.
      • Oh for the love of God in heaven! When will these Mystical Space Typhoon guesses end?!
      • Never, because an anime character simply using the card is an instant level in Badass.
      • Did it make Shark from ZEXAL more badass because he used it once? Just asking not arguing.
      • Yes, it certainly helped enforce his badassery (Face Heel Revolving Door tendencies aside).

Yuzu was supposed to get Xyz, but Sora changed that
Her bracelet has been compared to Overlay Units, she has a connection towards the Xyz-using Dark Duelist, and her a few of her cards can special summon other monsters out to her field. The show was purposely trying to get viewers to assume that she'll get Xyz, so they could subvert it with Fusion.

And it we go by the theory that Sora is a time traveler: the reason why he was so hesitant to teach her was because he knew that she was destined to use Xyz in the future. He's teaching her Fusion so she can get stronger, because in the future, she's likely saving the world ala every main character (that duels) ever in the franchise.
  • It is not impossible she can do both.

Sora is Yuya's and Yuzu's Kid from the Future
In Sora's timeline, Yuya and Yuzu were at the center of a 'Dueling Revolution', brought about by their shared mastery of all known summoning mechanics and as such, viewed as their generation's Yugi Muto. Hence his extensive knowledge of Duel Monsters: His parents are ones who re-discover it, so of course their child would know.

Under the pressure of the King and Queen of Games and being in the pro-leagues, one thing led to another, and the little guy was a teenage pregnancy. His hair-color and eye-color supports it (have a chart for ease of reading): Yuya: Green (and red) Hair - Red Eyes | Yuzu: Red Hair - Blue Eyes | Sora: Blue Hair - Green Eyes

He was sent back in time to preserve their timeline; what would happen if he doesn't is unknown, but the possibilities are largely narrowed down to (A) harmless alterations of history or (B) a Reality-Breaking Paradox.

The Meklord Genocide will occur.
So, as shown in Yu-Gi-Oh! 5D's, the planet itself seems to have an issue with Synchro Monsters. And, at some point in the future, the Meklord Emporers will arise, during a time when Duel Disks are made of hard light. This will be very bad for humanity. The Genocide was seemingly averted when Yusei and friends were told about it, but it may still occur as long as people use Synchro Monsters.
  • Ehhh, doubtful.
  • Or they will try to destroy humanity and fail because they were not prepared for a world where Xyz and Fusion monsters are used just as often as Synchro monsters.
  • It's not Synchro monsters that are problematic, the problem arises from when people use Synchro summoning for selfish or destructive ends. Momentum is basically Life Energy that can be influenced by Synchro summoning. When people Synchro summon with selfish emotions and desires, this negatively charges the Momentum, which in Z-One's timeline caused it to become uncontrollable and spawn the Machine Emperors and ultimately explode outright. Yusei designed a program known as Fortune to monitor the Momentum to prevent control loss. Thus, barring a Failsafe Failure coupled with ObstructiveBureaucrats, the possibility of a Zero Reverse or creation of Machine Emperors is nil. Again, Synchro monsters themselves aren't bad; it's the combination of negative emotion + Momentum + Synchro summons. We don't even know that the Duel Disk/Action Duel systems even operate on Momentum.

LDS is the reason we haven't seen anything about Yugi, Judai, Yusei, Yuma or their pals in a while
  • That's assuming they even exist in this multiverse.

Core (Yuya's cat) is...
  • an embodiment of the spirit of Odd-Eyes! As How to Train Your Dragon taught us, dragons are giant fire-breathing cats. The fact that Core also has heterochromia iridium is irrefutable evidence of this fact! Core will grant Yuya a fusion card to summon the newly leaked Beast-Eyes Pendulum Dragon. ... After he returns Yuzu's Polymerization to her.

Reji and either the Dark Duelist/Yuto or Kurosaki will duel for the duel at the end of the first arc
  • Jossed, despite the setup suggesting it.

Yuzu will enter the Junior Youth Championship and debut a fusion monster

ARC-V will retcon the endings of Duel Monsters, GX, 5D's and ZEXAL
It will be revealed that some of the vampires from GX survived the vampire genocide, and sticked around in the background, only emerging infrequently to turn certain individuals. note  They walk amongst humanity still, and reign over the YGO-verse equivalent of Denmark with iron fists.
  • Though the endings have not been affected yet, it seems that each new dimension the Lancers enter will explain certain mechanics that are exclusive to the dimension. So far, the Sychro dimension has done this with Riding Duels.

A Wyrm user will appear in the show at some point
Wyrm's not only work well with Synchro and Xyz monsters, but they are a new type, like Psychic in 5D's. And as we saw, Psychic types got a major focus as the monsters of Divine/Sayer's choice.
  • Probably. It'd be cool if he/she were like, Yuya's Synchro Summon mentor or something like that.
  • My money's on Yugo using Yang Zings.
  • Though people are predicting that he'll use a monster called X Y Synchro Dragon.
  • If Yuto and Yuya are anything to go by, he'll use High Speed Roids with Clear Wing Synchro Dragon as his ace monster.

Reiji will pull a Heel-Face Turn
  • It's Yu-Gi-Oh!, so here's another reasonable WMG. The Rival invariably is befriended by The Hero or at least tones down in the Jerkass quotient.
    • Seems to have done this ALREADY.
    • He's probably not done with his questionable methodology, but he at least has much more respect for The Hero as opposed to previous Rivals such as Kaiba or Kaito.

On Pendulum Monsters....
Pendulum Monsters can only be truly created by Yuya's Pendulum. This pendulum, a gift from his father, is an artifact that opposes the grand goal of LDS in a magical sort of way, and part of the way it does so is creating Pendulum Monsters. Without contact with the Pendulum, you cannot create true Pendulum Monsters, hence Reji's monsters malfunctioning slash looking, well odd and unnatural.

If conflict starts between the LDS and You Show Duel Schools, Pendulum Monsters will be the main weapon used by the students to protect themselves. This will mean that the Pendulum will give the other students Pendulum Monsters. Jossed. It took a lot of R&D, but Reiji eventually made working ones.

Sora is evil

Sora is actually an agent of the big bad behind the big bad.
  • Confirmed. He is evil, though how he fits into their ranks is unknown.

Yuya will Synchro Summon

The rings, to me at least, feel as though they suit him. Plus, Synchro is the least used summoning method yet, only be used by two duelists so far, while Fusion has been used by 3 and Xyz by 4. Considering his aversion to Sora and the amount of problems Xyz summons brought him, it is the logical call
  • If there is a monster that is both a Tuner and a Pendulum, then that would mean free infinite Synchro summons (as everything needed for it would go back to the extra deck, letting you do it again). Alternately, Yuya will get a level 8 Synchro Monster that needs Odd-Eyes Pendulum Dragon as a material.
    • And it will be called Chaos Shooting Odd-Eyes Ultimate Beyond the Pendulum Quasar Synchro Dragon Victory and it will have the most broken effect ever.
  • That sounds like a fast lane to the ban/limited list, but cool. (And C.S.OE.U.B.P.Q.S.D.V guy, let's try to be realistic here)
  • I for one propose "Future Imaginary Chaos Numbers -∞ 0 ∞: Elemental Masked Vision Destiny Contrast Neo-Space Black and White Magician Girl Hero Soldier King of Darkness and Light Wishes VWXYZ Jet Catapult Cannon Tank Formula Silent Honors Blue-Red-Galaxy-Odd-Eyes Shooting Ultimate Armed Shining Ancient Power Life Abyss Prime Cyber Chimeratech Ojama Ultimate Spirit Titan Photon Tachyon Storm Judge Burning Gagaga Gogogo Dododo Zubaba Over Fortress Etheric Flame Ninja Wing Tech Genus Comet Quasar Noble Sin Earthbound Sky Puppet Sphere Atlantal Killer Medallion Savior Machine Emperor Yubel Armityle Obelisk Osiris Ra Horakthy Zushin Numerronia Holy and Unholy Sacred Wicked Funerary Temporal Blade Metal Crystal Shark Rainbow God Beast Strings Macchu Mech Disaster Caestus Sandayu Stardust Daemons Rose Fairy Tool Stream Feather Resonator Fortune Synchron Junk Different Dimension Rebellion Entermate Infernity Oreichalcos Splash Ragna Hand Umbral Lightning Ragna Masquerade Attack Top Carrier Guard Core Supra Gluon Heart-eartH Coat of Arms Mist Knuckler Tanuki Polar Pegasus Devil Delusion Gunner Beyond the Victory Roots Ray Dyson Gimmick Superheavy Samurai OOPArts New Orders Lion Roid Gadget Vice Master Legendary Ark Halberd Leviathan Fantasia Hope MAXXX the Lady Dragon Knight Ruler, Envoy of the Beginning, Twilight, and End of Heaven, Earth, and Hell LV12/Buster."
    • ... I think I had this for lunch once.
  • ... Somewhat more reasonably, there may be a level 1 Pendulum Tuner monster that can only be used as a material for an Odd-Eyes Syncrho Monster. And there will be multiple Odd-Eyes synchro monsters, all requiring Odd-Eyes Pendulum Dragon as a material (and all being level 8). That would mitigate the problem of a Pendulum Tuner. Finally, they would all have effects tha would destroy themselves at the end of the opponent's turn, forcing Yuya to go back to the base form each turn.
  • Problem, Level 1 monsters cannot be Pendulum Summoned. They have to be in between a scale, and there are no scale 0 monsters.
    • Yet.
  • At the very least, it seems that Yuya will Fusion Summon, if Beast-Eyes is anything to go by.
    • Or that means it will be used in a Tag Duel that Yuya fights in.
  • Confirmed, Odd-Eyes Meteorburst Dragon is a level 7 synchro monster intended to be summoned with a Pendulum Tuner monster that can only tune with a dragon and can drop Odd-Eyes' level by 3 to make a level 7.

More duelists with older but popular archtypes will appear

Like the LDS rep trio and Mobius Sawatari, there will be more duelists using old archtypes. Wind-Up, Hero and Scrap being my personal guess
  • There could be a Geargia user, who will be a Sho Expy. Much like the Roids, Geargias look like toys, but they don't need the Magic Poker Equation to be a threat.
    • Geargigant X does make a cameo in Yuto's flashback of Heartland City, though anything else remains to be seen.

The Yu has power

Think about it. Yuya, Yusho, Yuzu, Yuto (The Dark Duelist), Yugo......It's like The middle D in Luffy's, Ace's and other's names.

Yuzu is adopted

When Yuzu questions her father about her bracelet, he says that she's always had it; she says that makes no sense, what baby is born with a bracelet on their wrist, and while Shuzou admits that that's true, he still doesn't answer the question. During all this, Yuzu's mother is nowhere to be found. Therefore, Shuzou found Yuzu when she was a little baby and she already had her bracelet at that time, thus explaining Shuzou's answer on where the bracelet came from.
The Mysterious D-Wheeler/Yugo is...
  • Someone who deliberately orchestrated an isolated Zero Reverse incident to destroy Heartland City.
    • and he is a hero for precluding any possible suffering of Yuma's dub voice.
    • That, or that's what caused him to be Driven to Villainy and vengeful, which makes him a reasonably sympathetic Anti-Villain.
    • Going to show up in the main.....timeline? Dimension? Whatever it ends up being as one of the main antagonists.
  • A user of both Synchro and Fusion monsters.
An older Yuma or a descendant of his will make a cameo at some point.

During the "final boss duel" Yuya will use all 5 dragons (if the rumors are true, Ritual, Fusion, Synchro, Xyz, Pendulum) and at some point all of them will be on his field at once.

Yuya will become the strongest protagonist yet
He already has a 'Beast-Eyes Pendulum Dragon' fusion monster in the waiting (If the Shohen Jump promo is any indication), whose to say that he won't find himself with more upgraded forms for a Synchro and Xyz Pendulum Dragon.
  • It will take a lot to top the likes of the Egyptian Gods and Shooting Quasar Dragon, though.
  • Being able to match Reji and use all summoning methods might be a good step towards it.
  • Rune-Eyes Pendulum Dragon has appeared. Beast-Eyes has appeared afterward.
    • Hard. Even 'though the deck would be terrible in real life, Atem is the only protagonist to have the ability to pull the card he needs when he wants to, and is the only one to have that as a canon ability. Something said in the last episodes, if i remember it right (Other protagonists do it, but it's mostly done by the script in a forced manner. With the exception of Yuma's transformation. But that is limited to a selected group of cards.)

The dub names will be...
  • Yuzu Hiragi - Susie Harrison
    • Her name is confirmed to be Zuzu for German dub!
  • Reiji Akaba - Ronald Akers
  • Rage.
    • It's confirmed to be Declan. Will his father and brother be renamed too? Desmond and Denzel, or something like that.
  • Sora Shiun'in - Sunny Sheldon
    • Most likely Sky or Skylar
  • Noburo Gongenzaka - Gerald Norris
    • Bob Gerald
      • It's confirmed to be Gong!
  • Shingo Sawatari - Soren Smith
  • Himika Akaba - Helen Akers
  • Masumi Kotsu - Julie Belle
  • Hokuto Shijima - Astro North
    • It's confirmed to be Dipper! (Northern Star theme is still there, though)
  • Yaiba Todo - Blade Torrence
  • Shuzou Hiragi - Samuel Harrison
    • It's confirmed to be Skip Boyle!
  • Ruri - Lily
  • Shun Kurosaki - Sean/Shawn Blackhawk
  • Yugo - Fyuse
  • Do we need to assume the worst? They only slightly changed the names of several 5D's characters (and some for the better if you ask me) and if the Yu in Yuzu's name is significant, they might try to keep it in. It's too early to say though. So we will see.
    • Yes, because this troper is The Cynic. And 5D's had a lot of English or otherwise non-Japanese names, like Jack Atlas, Crow Hogan, Rex Goodwin, etc. Aki's name change was stupid, several others were just blatant Americanization. Even Duel Monsters and GX had a field day with Americanization, and as for ZEXAL... Reginald Kastle. Enough said, really.
      • Or Adrian Gecko (lampshaded by Manjoume/Chazz). Or Anna Kaboom.
    • This troper sees "Soren" as an improvement over "Shingo".
      • This troper was too tired to come up with another S-name that was noticeably Americanized at the time.
      • He's always called by his last name, anyway.
    • If you ask me, the names of Yuzu, Sora and Reiji are probably safe from being altered too badly: the others have a decent chance of being altered though.
    • Actually this troper would like to point out that in the last few years unless your name is overly Japanese, the Dub names are... reasonable. Main character stays the same, the main female tends to have a similar name (Yuzu is difficult to work with mind you), the main rival will have their names unchanged (Kite. Kaito is the pronunciation people. And technically Shark, no-one calls him Reginald/Ryoga aside from his sister.) If you jave an English Name you're safe (Jack Atlas.) and most other characters either get sorted with similar names (Luka and Lua become Leo and Luna. Easier for kids to remember,) have their names almost unchanged (Kat,) or have it changed to something fitting (Flip). If one wants to argue on the details Bronk Stone is a name word linked with stone/metal family name (Tetsuo is Iron)... and don't ask me why they changed Takashi/Caswell. From one relatively standard name to another.
      • It doesn't really make sense in the case of explicitly Japanese characters who live in Japan itself. Granted, changing the names does make more sense in the case that the dubbing company caters the show towards kids, unlike the original demographic.
      • And what was the reason to change the names of Johan Andersen (Jesse Anderson) or Austin O'Brien (Axel Brodie)?
      • Apparently, even Johan and Austin too exotic for North American viewers. Too European, maybe.
      • But they always call O'Brien by his last name, anyway.
      • Troper who posted the text block above here. Johan, Austin and Declan all fall under the Caswell argument. That is, the argument of stupefying me. Although I would like to note that Gong is continuing another dub name tradition, shortened, similar sounding, names. Jounouchi becoming Joey. Jou-ee.
      • Actually, so far, the names honestly aren't horrendous. Gong is a shortened one, Ally for Ayu is relatively similar, Hokuto is Dipper, which retains the meaning of his original name (meaning "Big Dipper"), and though it might not be clear at first, Reiji to Declan is actually reasonable - they're both "rich kid" names (see Ace Attorney's Reiji Mitsurugi to Miles Edgeworth name change). Additionally, Yoko seems to be keeping her name, so we'll see about characters like Yuzu.
      • Gong and Dipper aren't names; they're objects. Ally is pointless, considering how easy Ayu is to pronounce. Declan loses the "zero" Family Theme Naming pun; even if it is kept in only as a Bilingual Bonus, the change still devalues the original. And Skip Boyle is just terrible. It's confirmed he's an adult; so it's most likely Nico Smiley (dumb, but not THAT dumb), or Shuzou.

Reiji's true motivation behind the Leo Corporation's actions is...
  • To prevent children's trading cards from destroying the world. He has watched the previous Yu-Gi-Oh! series, and has realized that such card games are extremely dangerous, what with all the Shadow Games, gods, demons, cosmic powers, Zero Reverses, and even aliens involved with them. So, by monopolizing Duel Monsters using the Leo Corporation, he can minimize threats to society. Furthermore, by assimilating all Duel Schools under LDS, he can easily identify Duelists capable of wielding powerful cards, so that he can appoint them to be safekeepers of such cards and guardians of society. He will eventually explain his plans to Yuya, offering him a prestigious position in LDS as well as appointing him to be the guardian of powerful Pendulum Cards, however Yuya will refuse and turn the whole thing into an Aesop about individual choices and free will prompting Reiji to Heel-Face Turn and rectify his actions.
    • Considering his comments about the "Lancers Selection," this may have some truth to it.
The LDS Duelist trio will return during the Junior Youth Tournament as direct opponents
Yuya will end up dueling at least one of the two he didn't duel before: either Yaiba or Masumi.
  • Jossed for Masumi. She lost to Yuzu.

A new Crossover with the other series will soon debut.
Reiji got his DDD cards at a cost of his soul, which he eventually has to pay
His DDD cards reflect his character already (see Fridge page) the Covenant cards do not reflect him yet. With this in mind, it is possible that he got his Deck from some unknown party that requires him to pay (whether he knows it or not). The "Pay 1000 LP each of your Standby Phase" part of the Covenants could reflect at the cards eating away at his soul slowly. Alternatively, the cards eat away at his sanity and mind, which is why he was laughing maniacally even though he is a Stoic type of character.
  • Additionally, they're the cause of his megalomaniacal desire to monopolize Duel Monsters, thus he is Slowly Slipping Into Evil. Eventually, Yuya will save him, resulting in his obligatory Heel-Face Turn.

Yuya will eventually get an upgraded, 3-headed Dragon called something along the lines of "Odd-Eyes Ultimate Dragon."
His ace follows the X-Eyes Y Dragon naming format that eventually got powerful, upgraded forms (in more famous cases with Kaiba and Kite). This will be Yuya's Ace Monsters Final and most powerful form (Essentially his equivalent of Shooting Quasar Dragon or Beyond the Hope).
  • Considering that Ritual Monsters are the only monster type other than Pendulum without a 3-headed dragon, this is fairly likely.

Gongenzaka will eventually have a You Shall Not Pass moment
His Deck was built for this.
  • I have a feeling it will happen in Ep.46.

At some point, there will be a three-way duel between Yuya, Yuto and Yugo to decide who the main character of the show should be.
It will turn out that Yuto and Yugo both want to be the main characters of the show, and of course, Yuya would have to defend his main character position. Yuzu may or may not get in on it too.
  • Probably nothing so meta, but I do support a three way duel between those three.
    • But if this duel happens and someone makes an Abridged Series of Arc-V then the abridged version will probably be to decide the main character.
    • W Hile not to decide the main character...it appears that it might actually be happening.

Yuto's deck is...
Based around the "Dark Rebellion" archetype, which has synergy with "Phantom" Magic cards. For example, one "Dark Rebellion" monster may allow him to send a "Phantom" Magic card from his deck to the graveyard, allowing use of the sent card's effect, to perform a search, while another may allow banished "Phantom" Magic cards to be activated onto the field, adding a recycling aspect. Additionally, he will obtain "Rank-Up-Magic Phantom Force" to evolve his ace. "Dark Rebellion Chaos Dragon" could be a likely name.
  • Jossed. His deck is more like Yuya's, focusing on the Phantom Knights monsters, but with "Dark Rebellion Xyz Dragon" as the ace.

Yugo will eventually Accel Synchro
To keep up with other characters' evolving aces, he must discover Clear Mind. Masaaki Endoh may assist with thise D in Luffy's, Ace's and the Xyz user, used Rank-Up Xyz Evolution, this is actually quite likely.
  • If the name Clear Wing Synchro Dragon is any indication.

Each universe's/time period's counterparts only have similar faces
  • The thing that disturbs Yuzu the most about Yuto is the fact that he looks like Yuya ... by his face. While he was masked, she saw no similarity to Yuya. Similarly, Kurosaki only starts thinking of Yuzu as Ruri after he sees her face. Neither her hairstyle nor voice reminded him of Ruri. Yuto realizes this fact, although he doesn't know that he has his own lookalike. However, it seems as though people can't distinguish them by all their other features that are different. The recent magazine reveals seem to confirm that Yugo has the face face as Yuya and Yuto.
  • Kurosaki and Reiji are counterparts. Both of their faces are somewhat elongated compared to other characters, and they have taller statures.

Yuto wants to mold Yuzu into his Ruri
  • Even though Yuto recognizes that Yuzu isn't Ruri, he initially takes the Polymerization card from her because he wants her to use Xyz like Ruri (possibly) did. He wants her to be a replacement for Ruri, even if he knows that they're not the same person.
    • He didn't actually take the Polymerization. He seems to have dropped it or put it back, since Yuya picks it up at the end of the episode, it having been missed when he put Yuzu's deck back in her duel disk for her.
    • Sora gave her two copies (if not three). We see a second copy as she looks through her deck in episode 18.
  • On the flip side, he said it didn't "suit her" because Ruri used it, and something happened to her as a result.
  • From what I saw so far, while Yuto does seem to be stalking her, I don't think he'd go that far. Mr. Shun 'I will steal people's souls' Kurosaki, on the other hand.....
  • Jossed. He mentioned Fusion as being their enemies' summon, but he's glad to see that she is using it to protect her own friends and secure her own future. He's actively trying to rescue Ruri from, according to Kurosaki, the captivity of Leo Akaba.

Arc-V stands for Arc of Five, namely, the five who bear the "Yu" Sound in their name.

There are multiple versions/counterparts of Odd-Eyes
Yuya has Odd-Eyes Pendulum Dragon. Yuto has Dark Rebellion Xyz Dragon. Yugo's Synchro monster might be "(X) Synchro Dragon". So maybe there will a "Fusion Dragon", a "Ritual Dragon" and maybe even a "Normal Dragon". And Yuya will get all of them. It wouldn't be surprising if even a "Tuner Dragon", "Toon Dragon", "Union Dragon" and "Spirit Dragon" will appear, but I doubt that.
  • Oddly enough, Beast-Eyes Pendulum Dragon retains the "Pendulum" despite being an EARTH Fusion version of Odd-Eyes.
    • Clear Wing Synchro Dragon.

Yuya will travel through time and will meet the other protagonists
Pendulum Summon is a hint that something like time travel might exist. Also, his pendant is basically a pendulum.

Shun Kurosaki is Haruto Tenjo
Both have psychic abilities. Eyes and hair same color. Xyz monsters and this city [1] is Heartland...
  • As much as I'd like to jump on this one, Haruto's hair is much lighter in coloration, and his supernatural powers disappeared after he was released from Vector's Demonic Possession. He's also really not the angry, bitter type, unless Kaito died. But in that case, he probably would be using Galaxy/Photon as opposed to Raid Raptors. On the other hand, a small part of this troper would be perfectly okay with him suddenly summoning any of the Galaxy-Eyes, Continuity Snarl aside.
    • Well, Kaito did have a heart condition.
      • That was a result of overuse of Photon Change when hunting Numbers. Haruto was the one with Soap Opera Disease, but apparently Demonic Possession and then being relieved of it cured him.
Odd-Eyes will get a three headed version of itself sooner or later.
  • The only "Eyes" dragon to not get a three headed version was Red-Eyes, other than that, Galaxy-Eyes and Blue-Eyes all have one. It only makes sense to me.
  • Someone already WMG'd the same thing above.

Yuzu will at some point try to track down Yuto while leaving her bracelet at home/with another character to see if she can get any answers without being interrupted that way.

Yuya and Reiji's duel in the One-Shot Manga will be recreated in the Anime
  • Maybe as their final duel together (though maybe not the last duel in the series).

Yuzu will be disqualified from the Junior Youth Championship
  • For using a 39 card deck, as a result of her not realizing Yuya took one of her Polymerizations. Thus, a whole clusterfuck of events is set off which could have been easily avoided if the writers were not so hellbent on screwing over the female characters.
    • Can we just assume for a moment the writers are not that bad. 5D's issues with Aki were not as much their fault as the guys in change saying 'Blackwings are selling like ramen at a Naruto convention, make Crow a major character'. Plus deck counts aren't really something that comes up in the show outside of Battle City's final and duels with deck out strategies.
    • The writers have a repeated tendency to shaft the supporting cast, but the females generally have it worse than the males, Executive Meddling aside. The last 20 or so episodes of ZEXAL, despite being a decent series up until then, went to crap because of the poor execution of the plot and undramatic slaughter of nearly the entire supporting cast. Granted, the duels were great, and even some of the character development was decent as well, but it was largely disappointing. Rio gets hit especially hard by this, even before the arc starts. Anna and Droite also are subject to this. Furthermore, even if they wanted to promote Crow to the forefront in the case of the 5D's anime, they didn't have to in a manner that completely and absolutely undermined Aki's role in Team 5D's. And the 40-60 card deck rule has been long established in the OCG/TCG. It's not unrealistic to assume that this would carry over to the anime.
  • In episode 22, she's seen looking for her card back at the docks, so she's aware of losing it. Plus, in episode 23's preview Yuya realizes he put Polymerization in his deck by accident and realizes his mistake. So chances of her card being returned are high. Plus, she should have extra cards. What replaces her field spell cards (When her cards were dropped, "Sanctuary in the Sky" can be seen. Action Duels require a special Field for players to move around and actually use action cards) when she's in an Action Duel?
    • This troper doesn't understand Japanese, so it was assumed she was looking for Yuto or something like that. And the reason she had Sanctuary in the Sky was because she wasn't dueling in Action Fields— she was purposefully avoiding You Show Duel School in favor of training at the docks with Sora. Granted, this WMG came about on the basis that she'd be too shaken up by her repeated incursions with Yuto to realize her deck was below the limit when building it for the tournament.
    • Considering she was looking for the card in episode 22, I'd say there's a good chance she won't be kicked out for a lack of cards. She'd aware of it, and likely can just substitute something else in, like a Mystical Space Typhoon as some people on this page fanboy.
  • Jossed. Yuya returns her card after his duel with Mieru. So there's no problem.

Yuya and Yuto cannot meet each other because they are the same person from alternate dimensions
In some science fictions, meeting your other self is impossible. If this happens, there will be a catastrophe, and the bracelet is made to prevent this.

Related to the above, if Yuya and Yuto do manage to meet at some point, something really strange will happen.
  • What would occur would result in a massive paradox causing ARC-V to go from a Shounen anime to a Boys Love anime.
    • Well, that one almost happened...
  • Or it ends up like the last Scooby Doo program, with reality resetting to the starting series, or something like that.
  • Jossed. Yuya is forewarned about Yuto's appearance and appropriately weirded out, but Yuto barely reacts at all.
    • Well, technically, something strange does end up happening...it just takes Yuto losing a duel and Yuzu's bracelet turning up at the same time to happen.

Yuya's best monster card will be a high level Pendulum monster that is hard to summon.
Possibly a monster with at least 10 levels, probably even 12, making it really hard to summon it. Also, it is likely that this card can only be Pendulum Summoned.

Hokuto will teach Yuya how to Xyz Summon
Yuzu asked Sora, Gongenzaka asked Yaiba. It actually makes sense. It is also the first or second step to master all kinds of Summoning.
  • Likely Jossed, as Yuya has now used Dark Rebellion Xyz Dragon, courtesy of Yuto and his Superpowered Evil Side.

Sawatari will use a low-level deck as his final deck
As a homage to Manjoume, Sawatari will realize that expensive, rare and high-level monsters are not always the best. Using an underrated, but strong deck would also give him massive character development. And which kind of low-level deck would fit? My choice would be Wight. Underrated, but really powerful.
  • Dustons could be a similar alternative.
  • Seems to be confirmed as of his most recent duel, using, believe it or not, a deck with actually a decent play in the meta, Yosenju. Furthermore, the deck only has one high level monster, Daibek, and his standard strategy is to summon the three level four monsters and make use of their card effects. As for the character development, he goes from being an actual Heel to simply playing the Heel/Face in his duel against Yuya, and becomes a Graceful Loser after his defeat.

Kurosaki's LDS hit list:
  • Next is Masumi, whom he will encounter separate from Yuzu, and Yuto will be too busy stalking Yuzu to restrain him.
  • Hokuto and Yaiba, in no particular order, will follow because they'd notice Masumi's absence. Alternatively, they may try to 3v1 him and still become subject to The Worf Effect.
    • Confirmed, since he does duel them in episode 24.
    • And smashes all 3 into dust on his second turn, which he starts off with no hand, no field, and 10 LP. Also Yuto was with Yuzu elsewhere at the time.
  • Very eventually will be Reiji Akaba.
    • Kurosaki encounters Reiji, but whether or not the duel will commence immediately is unclear.
    • It doesn't, Kurosaki instead becomes an Enemy Mine for Reiji, at least for the Tournament Arc.

There will be 5 Story Arcs in Arc-V

Yuya's great injury will not by Physical....
Instead, his use of the Polymerization Card in episode 23 will cause Yuzu and his friendship to utterly collapse.
  • The Polymerization card is out, as Yuya returned it. Though the friendship collapsing can still happen.

Somewhat related to the previous WMG, Yuya will duel against a Prophecy duelist
Who will be the Bigger Bad of the show and utterly crush him physically and mentally. Yuya's fortune was foretold via Tarot Cards, something that the Prophecy/Spellbook archetype is based off of. And coming off of the previous WMG, this Bigger Bad will not only defeat Yuya, but will do so after destroying his friends and family, breaking Yuya's spirit before defeating him in a duel.
  • Yuu Sakuragi is a Prophecy duelist, but he's a LDS student and seems to a nice student so far. Sakuragi is in the Youth Championship, so he won't face Yuya in the Junior Youth Championship. The only way they could face each other in the Maiami Championship is that both of them win their respective tournaments and then they have to duel each other to determine the true MCS champion. Coincidently, Sakuragi was the last JYC winner, so he has a chance to win the YC.

An antagonist will use a Qliphort deck
The Qliphort archetype is probably the strongest Pendulum archetype, so it could be used by the Big Bad.
  • That would be epic! According to art, Qliphorts are freaking huge. There should be a city-sized action field for that things.

The future Five-Bad Band, if there are at least five antagonists, will use decks specialized in the five different summoning methods. Alternatively, six.
If there are six, they will use Tribute, Fusion, Ritual, Synchro, Xyz and Pendulum Summonings. If they don't introduce new archetypes (which probably gonna happen) they gonna use "evil" archetypes. For example, Steelswarm for Tribute, Shaddoll for Fusion, Gishki for Ritual, Fabled for Synchro, Evilswarm for Xyz, and Qliphort for Pendulum.
  • If any will be subject to a Heel-Face Turn, it will be the Gishki user. Or, if they all eventually join the heroes' side, the Gishki user will be the first to do so.

Yuya has a split personality linked to his pendulum and/or the pendulum cards
The first time he ever Pendulum Summons and beats Strong Ishijima, he looks like suddenly coming to his senses at the end of the duel and was very confused about what just happened; like he wasn't himself while doing the combo. Later in episode 23, he feels crushed after drawing Polymerization because he didn't have any fusion monsters in his extra deck, but then seems to heard Rune-Eyes Pendulum Dragon and his attitude absolutely changes. When the duel ended he was again a little confused.

In Kurosaki's duel with the LDS trio.
  • The duel will be interrupted before it can end, or if they lose they will be saved by Yuto first.
  • One of the boys, mostly likely Hokuto since he's done less than the other two, will undergo a Heroic Sacrifice to save his friends.
    • Both Jossed, he One Turn Kills all three of them with his ace, Raid Raptors Rise Falcon.

Yuya is a clone of Yuto.
  • Alternatively, they're both clones from the same source. The point is, Leo Corporation had a department attempting to genetically engineer superpowered duelists, but, for whatever reason, Yuya came up short. Yusho, working in the department, took pity on him and adopted him, raising him as his own son. However, Yuto escaped, prompting Leo to call in Yusho to help track him down, otherwise he would have to forfeit Yuya for testing to replace Yuto. Not wanting Yuya to be caught up in all of this, Yusho disappears without a trace, in order to capture Yuto, so that he can keep Yuya safe from Leo.

When Yuya duels Gongenzaka
  • He will discover Pendulum Synchro.
  • Discover the power of Beast-Eyes Pendulum Dragon
  • Tie or Win, but a technicality allows Gongenzaka to be in the tournament anyway.
    • The qualifications are based on win percentage. Yuya was just shy of meeting the requirements, but Gongenzaka has probably won enough that he can still qualify even after losing to Yuya.
    • Jossed, but Gongenzaka still has time to get a few more duels in to fix that. Confirmed, he made it in time for another episode.

Yuzu will become very hot in one or two years
The only reason why she looks like a childish character is because she is 14. If we look how hot Anzu, Asuka and Aki are, who were 16 at the beginning of the respective series, and how much Rei has changed between two years (from 11-12 to 13-14) and how beautiful Luca has become in the epilogue, it is probable that Yuzu will also turn out like the others.
  • Kotori's classmates were practically drooling when they saw her mother, as their reaction was, "That's what Kotori is going to look like!"
  • Well, at times she does look like she's half way there. At least to me, she looked rather busty in episode 34.

Sora defected/ran away from the Fusion Faction
  • Sora used to work for Yuto's enemies, but decided he didn't want to fight anymore and left for Maiami City.
  • However at some point he'll either choose or be forced to rejoin and become an antagonist.
  • Partially jossed, he's a part of it, and no defection yet.

Yuya will later obtain Ritual, Synchro, and Xyz versions of Odd-Eyes Pendulum Dragon.
He's already got a Fusion version in the form of Rune-Eyes Pendulum Dragon, and by extension Beast-Eyes Pendulum Dragon, so this might be a possibility.
  • To clarify, this WMG is not about the counterparts like Dark Rebellion Xyz Dragon, but Odd-Eyes' own versions.

There is/was a Summoning War in Yuto's world
Yuto and Kurosaki are Xyz users and their enemies are a unknown Fusion faction, and Yugo the Synchro user, who is probably not allied with the former. I guess there is a war between the four Summoning factions.
  • In which case, maybe Leo Corp knows about it. Which is why they want to achieve a total monopoly; they're uniting all of the summoning methods under a single banner.
  • Confirmed. Fusion vs. Xyz.

When it really counts, Sawatari will be the one to take down Kurosaki.
Kurosaki's Rise Falcon is incredibly powerful, but only against Special Summoned monsters. Sawatari's latest deck uses Monarch, which are all Tributed summoned.
  • Except he ditched decks again for Yosenju, which has a heavy Pendulum focus.
    • But with the way his deck works, allowing for multiple Normal Summons and sending his opponent's cards back to the deck under the right circumstances, if Sawatari makes the right tactical decisions, he could still defeat Kurosaki unless he has a counter for multiple Normal Summoned monsters as well.

Future antagonists will start using Shaddolls, Qliphoths and other archetypes
And those duelists are aiming for The End of the World as We Know It, they may also be connected to Yuto and Kurosaki.
  • There is already a WMG with the Qliphoths. Another WMG also speculates the Shaddolls.

The "Summoning War" is a war between multiple dimensions
Yuto and Kurosaki are from the dimension Yu-Gi-Oh! ZEXAL takes place in (they all use Xyz and the city they come from appears to be Heartland). Yugo is from the same world as Yu-Gi-Oh! 5D's (uses Synchro and has a D-Wheel/Duel Runner) The enemy that uses Fusion is from a world where fusion summons are still used frequently (Possibly the one Yu-Gi-Oh! ARC-V takes place in) or even one where the other extra deck summons were never developed. (possibly Yu-Gi-Oh! GX but probably not because GX is the past of both 5D's and ZEXAL)

Arc-V will reveal a Yu-Gi-Oh! multiverse
Going on the above thoughts.
  • Loosely speaking, the YGO-verse already contains a multitude of dimensions; Earth's universe, the Dominion of the Beasts, Neo Space, the Astral and Barian Worlds, the Shadow Realm (loosely), the two dimensions from GX (the one that the Academy was sent to, then the other one). If Misawa's 'twelve dimensions' estimate in GX holds any water, that leaves four dimensions to be named and visited; five if the Shadow Realm isn't counted. There isn't really much of a reason to include alternate earths.

The Time Traveling of the last season of 5D's resulting in a split timeline, whose branches are fighting one another.
It is known that Duel Monsters, GX, and 5D's all exist during different times in the same continuity, due to Bonds Beyond Time. It is unknown when or where ZEXAL fits into this; monsters from Duel Monsters and GX exist in historical records, but there is no mention of either the events of 5D's, or Synchro monsters. Conversely, 5D's never mentions either the events of ZEXAL or Xyz monsters. The theory is that the time travelers from 5D's created three universes: one is the one shown at the end of 5D's, where the Meklord genocide is averted, and another is the past of ZEXAL, where it was not. However, rather than the complete genocide that Ylliaster came from, th world of ZEXAL was able to fight back, due to the development/discovery of Xyz monsters, which would No Sell anything the Meklords would try against them. Thy were able to rebuild, and the concept of Synchro summoning and anything related to it was Un Personed. The former is the timeline of the Synchro Faction, the latter is the timeline of the Xyz Faction. The third timeline is the one where Paradox succeeded. He didn't stop the game from taking off (it was already way to late for that), but he did make it so that neither Synchro nor Xyz Summon was developed. This universe also averted the Meklord Genocide, but the best it can come up with is Fusion summon. This is the timeline of the Fusion Faction. Something is bringing the three of them together, and everyone is fighting just to survive.
  • So where does the Arc-V timeline come in?
  • Arc-V would be the unified timeline (hence having all of them).

Yuya's summoning methods (sans Pendulum summon) are progressing as the series as a whole did
First, Yuya normal summoned Odd-Eyes Dragon (ala the original series) then, ignoring Pendulum Summon, Fusion Summoned using Yuzu's Polymerization (GX) and next, he will probably Synchro Summon. Then Xyz Summon.
  • Actually, the true GX Fusion Summoning he will learn is Contact Fusion. Beast-Eyes Pendulum Dragon is a Contact Fusion Monster.
    • Apparently, Beast-Eyes Pendulum Dragon isn't a Contact Fusion Monster in the anime.
      • In the real life game, it turns out that Special Summoning this card with Contact Fusion is optional. This card can be Fusion Summoned with a Fusion card as well.
  • There will probably also be an Accel Synchro and CXyz version of Odd-Eyes.
  • Jossed, he got XYZ before Synchro. It is instead a case of Yuya's summoning methods evolving as the Arc-V series revealed them. (Fusion with Sora, Xyz with Yuto and Synchro with Yaiba).

When Yugo appears in the present
  • He will be an Affably Evil Punch Clock Villain, as a foil to Kurosaki and Yuto.
  • Or otherwise not be as bad as he appeared to be in the flashback.
  • He feels like he is the underdog, just trying to survive against the onslaught of Xyz users.
  • Confirmed, with a hefty dose of klutz and goofiness that seems like the end result of having Yuma in Yu-Gi-Oh 5D's.

When Yuya summons Beast-Eyes, the other fusion material will be Silver Claw.

Yuya, Yuto, Yugo and maybe Yuzu are keys to larger plot.
Someone has a plan that involves "masters" or a specific Special Summon type. Three of them are already known, Yuya (Pendulum), Yuto (Xyz) and Yugo (Synchro). which leaves Rituals and Fusions. These five are keys to a mysterious plot that may be revealed later in the series.

Yugo is not a Synchro user, but a Fusion user
It is only assumed by the fans that he is a Synchro user because he's a D-Wheeler, but it was never stated whether his monster really was a Synchro monster or not. We know that Yuto and Kurosaki's enemies use Fusion monsters. During the 3-on-1, Kurosaki only got an angry reaction towards Masumi's Fusion Summoning, but not to Yaiba's Synchro Summoning. There is also an implication that Yugo is connected to Ruri's kidnapping. Yugo's name is a homonym for the Japanese word for "fusion" (e.g. 'Yugo' Shoukan). And in 5D's there were at least three D-Wheelers who used Fusions: Jack, Sherry and Yusei. Ergo, I think Yugo is a Fusion user.

Odd-Eyes is the Crimson Dragon
Odd-Eyes is red, and Rune-Eyes has the exact same roar like the Crimson Dragon from 5D's. Yuya will evolve it so much, that it turns into a god.

Yuya will reacquire a copy of his original Odd-Eyes Dragon card.
All we know for sure is that just Yuya's copy of Odd-Eyes Dragon transformed into Odd-Eyes Pendulum Dragon, not every single copy of it in existence, meaning there is a chance he could find the card of his dragon's original form and add it to his deck for double the dragon beat down. Besides, if Yuya does manage to gain an Xyz version of Odd-Eyes like a previous WMG says, he's gonna need all the support he can get, since Xyz Monsters do require at least two monsters of the same level to summon and so far, Yuya doesn't really have any other level 7 monsters in his deck.
  • Assuming that his Odd-Eyes Dragon wasn't an original card that didn't have any copies. The Signer Dragons didn't have copies (except the three Red Dragon Archfiend fakes), and the Numbers were obvious.

There will be a 15th anniversary film.
Similar to the 10th anniversary one, it will have Yuya teaming up with his two immediate predecessors; Yusei Fudo and Yuma Tsukumo.

The true reason for Yusho's disappearance
  • Something to do with Leo Akaba. If his claim of Leo kidnapping Ruri is correct, then it's not much of a stretch to presume that he could have done the same to Yusho. Reiji seems to affirm that his father is beyond the Moral Event Horizon.
  • It's possible Leo threatened Yusho instead of kidnapping him. He may have used Yuya as his bargaining chip so Yusho would comply to his wishes.

The little hooded boy is Reiji's little brother
He was show alongside him in the championship's inauguration, has silver hair and blue eyes. Also, episode 28's preview shows that he's quite scared of Himika Akaba. This is because he's an Akaba himself and his mother is pushing him too much into fulfilling very high standards in order to make a prodigy out of him. After all, having an older, professional genius duelist brother can leave a younger sibling under a very large shadow that a very dominating mother will want to repeat, without considering his feelings.
  • If the name Reira is any indication to his connection with Reiji. The majority of Kaiba expy's have little brothers (Kaiser, Kite, and Shark who has a little sister instead). The only exceptions are Jack and Manjoume, the latter being the youngest brother — well, Manjoume is the most poor YGO rival ever (not counting his manga counterpart). And with "poor" I don't mean money.
  • Confirmed. Although the Versus Character Splash spells it "Layra."

If Yuya ever becomes evil, his Performapals will turn into dark slave animals, cage animals or both
Remember the Evil HERO monsters? What would make circus animal look dark or more dangerous? Slave or cage animals.

If Yuya ever becomes evil, he will be the most terrifying Dark protagonist to date.
He's going to go on putting on a show, but in full Monster Clown mode. He will put on a performance even Rakdos would find impressive. Ladies and gentlemen, prepare to hear the screams of condemned.
  • That actually sounds awesome.
  • With inspiration from Sora, I guess.

Reiji erasing the LDS trio's memories will come back to bite him in the ass.
  • His expies (barring Kaiba) tended to receive a comeuppance or Humiliation Conga for their morally ambiguous/wrong actions.
  • Masumi might even remember due to the results of her duel with Yuzu.

Sora will reveal part of his backstory to Yuya and Yuzu after his duel against Kurosaki.
  • He revealed it to everyone during the duel.
Masumi and Yuzu will be in a tag duel together at some point.
  • Gem-Knight Seraphinite requires a LIGHT monster and is a Fairy-type Fusion, it is perfect for them.
  • Or maybe Hokuto since it looks like a Fusion of Lazuli and Constellar Virgo, according to trivia.

Yuya will gain new monsters with Pendulum Effects that provides very good support towards Synchro and Xyz summoning
And that will be how Yuya takes Pendulum Summoning even further. This is based on the fact he currently has a monster whose pendulum effect allows him to fusion summon once per turn. And the effects that might work for this idea:

Yoko, Yuya's mother, was once a professional duelist herself
It'd be cool to be the son of TWO pros, no?
  • It would also be cool of Yoko was Yusho's partner when he was pioneering Action Duels, which could make her a co-pioneer of Action Duel as well.
  • Confirmed in the summary of Episosde 52. She challenges him to a duel.

Reira's Deck uses the Outer God, Elder God, and Great Old God cards.
Think about it for a moment. Himika is trying to make Reira a prodigy like Reiji. What's Reiji's claim to fame? Using Fusion, Synchro, and Xyz in one Deck. With the reveal of Outer God Azathoth, which has a nuke effect if it has all three of the above as Xyz Materials, the Lovecraft Gods focus on pulling the same thing that Reiji can, so they would be the perfect cards for Himika to have Reira use in order to make him as good as Reiji.
  • Looking at those cards, they rely on a duelist using Fusion, Synchro and Xyz summons in perfect tandem, plus they don't look so powerful that they'd be better seen in their dad's hands so it looks like Reira can have them. The only problem is that none of them explain what Reira is doing in that preview.
    • Jossed. Reira seems to be using a CC(C) deck that copies the opponent's monsters.

Alternatively, Reira is NOT Reiji's brother. He is something very disturbing, like Reiji's or Leo's clone, or prisoner from another dimension!
Why would Himika and Reiji to hide their relation to Reira from everyone? Akaba family is famous in this world, yet no one seems to know if Reira is part of this family. His last name is not even called once! Plus, Himika and Reiji act very cold and distant to him.
  • Maybe they are just aloof to him. Mokuba wasn't famous, and Kaiba was aloof to him at the early part of the manga. Also, when Reiji is introduced to the heroes, only Shuzou had an idea who he really was and looked it up on the internet.
  • His deck could be a hint on something, since in Yu-Gi-Oh!, cards are always used as reflection of duelist soul. His main strategy is creating copies of opponent's monsters. Copies looks almost like original, but had to be destroyed at the end of phase.
  • Confirmed in Episode 67. He was a war orphan, picked up by Akaba family and brainwashed to be a duelist.

Leo and Himika Akaba will use "AA(A)" and "BB(B)" monsters respectively.
  • Aqua Agent (Admiral) and Brutal Beast (Baron), respectively?
    • "AA(A)" could be "Aqua Actress", which is what Ayu used. The extra "A" for the extra deck monsters could be "Ace" or something.
    • "Aqua Actress" is written in kanji, though. Whereas DD(D) and CC(C) use the English letters.
      • It's not in kanji, it's in katakana.

During Yuzu and Masumi's second duel.
  • Due to the reactions of Masumi and Kurosaki in the preview, the memory erasure will be broken when Yuzu tells them.
  • The duel will end up in a draw or canceled because of this.
  • Or Masumi will lose because her scrambled memories make her sick or something.
  • If she does regain her memories, she will be dismissed by the rest of LDS and be ostracized and thought of as hallucinatory. Reiji will attempt to reinstate the memory erasure.
  • All 4 jossed. The issue only comes up in Yuzu's head, and the duel proceeds like a regular duel. In the end: Yuzu wins.

The MCS Finals will be...
  • Yuya vs. Kurosaki. Yuya obviously wins.
  • Yuya vs. Sora, who has shown his true colors as the Big Bad. The only reason he helped the other was because he wanted someone interesting to duel. Yuya wins, and Sora vanishes to cause more trouble in the next arc.
    • This one is Jossed, with Sora's loss to Kurosaki.
  • Yuya vs. Yuzu. Yuya loses. (AHAHAHAHAHAHA No. If only it were possible, but alas, Yu-Gi-Oh! must be Yu-Gi-Oh!)
  • Or the tournament will be interrupted, before it can even finish by the villains.

At some point in the MCS, Yuzu will have to duel Yuya.

Leo Akaba is the same Leo from 5D's. Not Rua! The son of Yusei's landlord, the clock guy (known as Lyndon in the US version)
He married Himika for money and also took her last name. After event of the show, he became too obsessed with clocks. He studied them so hard that he accidentally broke the very fabric of time and space. It lead to chain of events, which created a lot wormholes from different times and alternative timelines, centered in Maiami.
  • Doubt it, not a single person liked that character, no one would bring him back.

One of Odd-Eyes' evolutions will have wings
The wings symbolize the evolution and Yuya will use its flying abilities to increase his skills in Action Duels.

Yugo is actually counterpart of Sawatari, not Yuya
Just look at his smug face in the new opening!
  • Recent scan leaves this up for debate.
  • And now some people convinced he is a counterpart of Sora! Let's start making bets.
    • Jossed after Episode 35. He has Yuya's face too.

From the position in the 2nd opening...
Because Sora was shown with the LDS students in the opening, he will end up leaving You Show and joining LDS, whether or not because he ends up losing to Kurosaki for whatever reason.
  • The 2nd ending also doesn't show Sora up to greet Yuya in the end like the others.

Similarly to how Yuzu initially mistook Yuto for Yuya, someone Yuto knows will at some point initially mistake Yuya for Yuto.

Future MCS duels will be...
  • Yuya vs Yuzo Tanegashima, the ace of the Surprise School who looks suspiciously similar to Yusho.
    • Jossed. Gongenzaka is dueling this guy.
  • Yuzu vs Mikiyo Naname, the ace of the Duel Girls Club. She also looks like a Fairy-type user.
    • Confirmed.
  • Gongenzaka vs Isao Kachidoki from the Ryozanpaku School, who looks like an Asian folklore-based fighter.
    • Jossed. Yuya is dueling Kachidoki.
  • Gongenzaka vs one of the Knight School. Samurai vs Knight.

The Leo Corporation rocket in the second opening is actually an ICBM
  • Leo Akaba, being a megalomaniac, decides that his course of action will be to Nuke 'em. It will be disarmed in the nick of time, however, thanks to the protagonists defeating him at a children's trading card game.
    • Naturally, the dub will refer to it as a "Shadow Realm Rocket" or have some other ridiculous excuse to enforce the Nuclear Weapons Taboo.
      • I'd like to question how the above poster thinks they're going to get it past FCC without neutering it or... turning it into a laser. Laser would be cool

Pendulum Monsters existed before, but were Ret Gone'd out of existence
For an instant, Yuya knew exactly what to do with the Pendulum cards once he got them, and the technology had no trouble handling them as well. We also know that Leo Corp has mind erasing tech. All of his Pendulum Monsters were sealed before he got them, but his pendant unlocked the seal, reintoducing Pendulum Monsters to the world. For a second, he broke through, and remembered how his father did it, but that moment soon passed.

During Kurosaki's and Sora's duel
  • The LDS trio will finally regain their real memories, prompting them to confront Reiji.
  • Sora is going to Fusion summon a powerful monster. The Fusion materials, two FUSION monsters.
  • Sora will use the Frightfur Factory card to summon his true ace, because of Foreshadowing.
  • Kurosaki will Rank-Up his Rise Falcon.
    • The one on top is Jossed, Frightfur Factory one is partially confirmed because he didn't use it to Fusion Summon his ace and the other two is fully confirmed.
      • Confirmed and then some. Three Fusion Monsters, two Rank-Ups.

The events of episode 35 will strangle Yuya and Yuzu's friendship
The preview of episode 35 shows Sora dueling Yuto and Yuya intervenes and (finally) gets to see Yuto face-to-face. Most probaly Yuto will identify himself as one of Kurosaki's comrades. Yuya will then take it bad, after all Kurosaki injured Sora and turned Yuya's precious Action Duels into a battlefield, so he'll side with Sora out of friendship without knowing better.

But, when he gets to tell Yuzu about Yuto, Yuzu will try to explain to him Yuto and Kurosaki's side of the story as she get to interact wth Yuto more than Yuya did. Yuya will then get furious that she has been keeping Yuto's existence secret and will see her bad for siding with someone that injured Sora. This will get a very bad stain on their relationship and will be a Deconstruction of The Power of Friendship theme that it's all around Yu-Gi-Oh series.
  • Seems to be somewhat confirmed. While there is no strain so far on their friendship, this causes Yuya to side with Sora (or rather, the prospect of Yuto hurting Sora does.)
  • Jossed. Aside from Yuya actually questioning Sora's motivations, he and Yuzu talk about the plot in episode 38.

Sawatari isn't the one who is a Decoy Main Character
Sora was the decoy all along, and his main character status will be claimed by both Kurosaki and Yuto.

On Sora and LDS' connection with Academia
The first time we see Sora he's at one of LDS' schools, most likely looking to enter the school's fusion faction; but changes his mind after seeing Yuya and Pendulum summon, allegating it was more interesting that whatever LDS have to offer. Thanks to episode 34, Sora is revealed to belong to (or used to be in) the Fusion faction that destroyed Heartland as a Hunting Game; but Kurosaki's target are clearly LDS and more exactly Leo Akaba and the 2nd opening suggests that LDS used to made nuclear missiles and it's highly implied that Heartland was destroyed with nuclear weapons. So my theories are:
  • Academia is a group created by Leo Akaba, built around Fusion users (and maybe, secretely some Synchro users). Why they decided to target Heartland still it's unknown for me, but right now, For the Evulz is a reason as good as any.
  • Sora was send by Academia to enroll in a LDS school in Maiami City in order to spy on Reiji, but after meeting Yuya and Pendulum summon, his curiosity and his looking for new and exciting opponents won him over and he decided to defect, or considered Pendulum a big asset in his Hunting Game and wanted to studied it closely (and in the best scenario, reclute Yuya).
  • And the 2nd OP and ED suggest that Sora will join LDS. This looks very out of character, unless this reflects that Sora was originally suppossed to be among LDS and will be commanded to join as he was supposed to. He probably will do it in order to search for a rematch against Kurosaki, who seems to be staying close to Reiji for a while now.

The important MCS battles are not chosen randomly, but on purpose
It's very convenient that Yuya vs Sawatari and Sora vs Kurosaki happened at the beginning of the tournament, especially both of them are working for/with Reiji. It's very likely that these matches are not coincidences, like the matches in the Fortune Cup which were obviously organized before. It might be possible that even Yuzu and Gongenzaka's matches were organized, so Reiji can test them as well. It would fit to his character if he has a lot of information about the participants beforehand and organizes their matches to test everyone to their fullest potential.
  • It's implied this is quite correct.

Reiji's Lancers will be Summoning Specialist
A specialist for each summoning method. That would be Fusion, Ritual, Synchro, Xyz and Pendulum. Also Tribute. Bonus specialists would be Contact Fusion, Accel Synchro and Xyz Change if he really wants them. Putting them aside, Reiji would have five or six Lancers, with him as the Big Good. Five-Man Band with Sixth Ranger or The Magnificent Seven Samurai?
  • Not likely. When Kurosaki broke out Rank-Up Magic, Reiji had no idea what it was. And the preview of ep. 37 has Yuya be shocked that someone would duel while riding a motorcycle. Doesn't mean that, when the actual WAR comes to Standard, they wouldn't have developed their own RUM from Kurosaki's example, but Accel Synchro seems unlikely simply on the sheer fact of not everyone is doing Riding Duels. Contact Fusion is another matter entirely, since it's an easy enough mechanic to include in card text.

In the Yuto vs. Sora Duel...
  • Yuzu will show up, and since Yuya is there, Yuto will be teleported away by the bracelet, leaving the result inconclusive.
    • This happens right as Yuto activates a Rank-Up-Magic.
      • Seems to be Jossed, as the preview indicate that Yuto will be sticking around for a few episodes, but could still happen.
  • Des-Toy Scissor Bear will be unable to equip itself with Yuto's Spell Monster Cards, since they will be banished if they leave the field. Even if they would go to the graveyard. They are Spell Cards in the graveyard and not Monster Cards.
    • Jossed. It successfully grabs an Xyz Monster.

The threat to the Astral World at the end of ZEXAL was Academia and the ZEXAL cast was defeated and/or killed off
Kurosaki's and Yuto's flashbacks show a completely destroyed Heartland City. Yuma and co. are seen flying to the Astral World at the end of ZEXAL to face some new threat—Academia. They failed to subdue the threat and were killed in the process. This allowed Academia to cross over to Heartland City and start their hunting games as the world was powerless to resist due to their strongest all dying. Basically, Yuma and crew fucked up and Heartland (and presumably the rest of the world) went under siege as a result. The Resistance is the remainder of the world that decided to fight back.
  • Additionally, Academia is the Duel Academy from GX, which was conquered by some evil forces. Judai suddenly left the Duel Academy in the end of the series and the rest graduated (except Kenzan and Rei). So there was nobody left except the facility (and Kenzan and Rei) to protect the school.

The summoning factions home bases are all settings from previous series.
Forgive me if this has been brought up before but it seems like this could be a very real possibility. It's simple really: Heartland is already confirmed as the place where Yuto and Kurosaki come from. Academia could very well be Duel Academia and of course, Yugo's faction, if apart of one at all, is based in Neo Domino City. Whether or not they're from different dimensions or timelines is a different point entirely, of course.
  • If Yugo really is a Synchro user. As mentioned above, it would be odd if someone whose name sounds exactly like "fusion" in Japanese would not be Fusion user.
    • In the 2nd OP you can see his card plate has a white card on it— a Synchro monster. Though it's not impossible that he uses both.
    • When Yugo was shown summoning his monster during Yuto's flasback, the background was similar to the one used for Synchro summon.
    • Yugo is indeed a Synchro user, with two of his Synchro monsters now revealed.

Sora has some kind of Split Personality.
It's entirely possible he is actually pure evil, but then why would he help Yuzu when he had no reason to? He even mentioned he might get in trouble if he did, but agreed to anyway. Presumably it isn't a Vector situation either, since Bloom Diva isn't a card he pulled out of thin air. And while he's gotten irritated at people belittling him before, it was only when dueling Kurosaki, an Xyz that he flew off the handle. So it's possible there are two Soras - one who is prideful, but still well-meaning, and another who is completely smug (looking down on Kurosaki's ace monster having weak attack, when before he was able to identify how this meant another was a threat) and cruel, and was the one who fought the Resistance. When Sora wakes up in the next episode the first one will be in charge, and the only thing he'll remember is Kurosaki humiliating him.
  • Alternatively, he could have just been trying to recruit Yuzu into his Fusion cult.
  • Quite possibly. If he was, though, you'd think he would try to avoid looking as suspicious as he did against Kurosaki - even if they couldn't hear what he was saying they did see how aggressive he was acting. And that could be another hint of this being true.
  • He might have Jumped Off The Slippery Slope because he was unable to handle the fact an Xyz duelist was counterplaying him so soundly. Extra points for being explicitly bigoted and being accustomed to defeating them with ease. He didn't mind getting defeated by Yuya because Yuya isn't "Xyz scum."

An ARC-V episode or movie will live up the promise between Atem, Judai and Yusei
Several posts above mention that Time Travel may occure in the future and the five protagonist will meet together. In the 10th Anniversary movie, Atem, Judai and Yusei promised that they will meet each other again. ARC-V might give it the opportunity to make it come true.
  • Yu-Gi-Oh! movie site teases silhouettes of Yugi and Kaiba.

Tatsuya is more than meet the eye
He wasn't the member of You Show Duel School from the beginning, he joined only after learning about Yuya's Pendulum Summoning. We don't know a lot about him, we never saw his parents, unlike with Ayu and Futoshi. He is way too smart for his young age (as we saw during Quiz duel). Also, accidentally(?) he has the same hair and eyes color as Yugo The Mysterious Rider.
  • His mother appeared in the first two episodes.

Either Yuto or Yugo will be revealed to have a last name with "Jo" in it...
...to fill the quota of obligatory YuJo friendship/rivalry of franchise.

Yugo is a lone mercenary, and possibly a Psycho for Hire.
Episode 37's summary calls him "The Fusion Side's Agent", meaning he works for Academia, yet he uses Synchro Summoning, not Fusion. Yugo may only be working for them because he gets paid a load of money or because he likes destroying stuff, as hinted at by his Slasher Smile in Yuto's flashback.
  • Or they pay him with cards. Remember Sawatari's trio?
    • Welp, this was Jossed. Yugo's not even with Academia, and he's not a psycho, either.

The Fusion Faction will give Yugo the card Miracle Synchro Fusion
Because with a name like that he's gotta Fusion Summon one way or another.
  • But he would only use them in a Turbo Duel, since it's a Speed Spell Card.
  • There could be Speed Spell and non-Speed Spell versions.

Turbo Duels will return
We have Yugo after all.
  • Alternatively, Yugo will ride circles around his opponent, who will be standing completely still. On. The. Ground. (Thus making it not a true Riding Duel).
    • Confirmed with his duel against Yuto.
    • Yeah, that happened in 5D's against Goodwin. And he even used the rules against the trio, even though, he was cheating (he attacked them with evil forces that have nothing to do with the duel).
    • Perhaps more visually interesting, it could be a Turbo Duel, where he is on his D-Wheel/Duel Runner, and, through whatever power gives mass to Yuto's monsters, his opponent would be riding on a monster, like in Action Duels.
    • Or rather, he will always ride his D-Wheel in an Action Duel, thus giving him a distinct advantage.
      • Distinct but not necessarily powerful. He would be very good on a straight, even surface. But if the terrain is rough, or the trail too irregular, he may be better off on foot. Unless he can dock his D-Wheel with Clear Wing...
    • Does attempting to run over Yuto during their duel count as an advantage?
  • Confirmed as of episode 54, complete with the intro changing from Action duels to Turbo duels

Yuzu will be brainwashed at some point of the story
Anzu by Malik, Asuka by Saiou, Aki by Divine, and Kotori by Girag. Do you see the pattern?
  • And there was Rio by Abyss, too (though Aki was more indoctrinated than brainwashed). Perhaps Ruri is already or will be brainwashed as well?
    • I meant the main female leads. Rio and Ruri aren't main females. Also, it's explicitely mentioned by Divine that he "mind-controlled" Aki.
  • I forgot to mention that Anzu was brainwashed by Shadi in the manga, too.

Yuya will have Odd-Eyes, Rune-Eyes and Beast-Eyes at the same time on the field in the middle of a duel
The 2nd opening might has given Foreshadowing. Odd-Eyes Pendulum Dragon is a Pendulum Monster, so it can be easily Pendulum Summoned from the Extra Deck even when one or both of the Fusion dragons are on the field.
  • It's possible to do in the real game. Had all three out at the same time in a duel. Though I had multiple copies of Odd-Eyes Pendulum.

The shadowed person in the 2nd Opening is Ruri
The person right after Yugo. Some fans suspect that it's Ruri and they are at least convinced that the person is female.
  • Possible but unlikely. Lightening the image gives you a pretty good view of the face, which has the same structure, in addition to the exact eye structure, as Yuya, Yuto and Yugo. It's most likely the Academia-aligned version of Yuya.
  • The person is revealed to be Yuri. And judging from the face, it's apparently another Yuya-lookalike. Also, Yuri has no girlish eyelashes, so Yuri is probably a guy, regardless of the pink part of the hair.

Yuzu is Ruri
Yuzu doesn't resemble her father in the slightest, but she and Kurosaki have the exact same hairstyle (watch the bangs). Moreover, Shuzou does not know where her bracelet came from, only claiming that 'she's always had it'. Yuzu correctly points out that she can't have been born with it. Likely, Ruri escaped (or was rescued) from the Academia after having her memories erased, was found with the bracelet on and adopted by Shuzou. Following from that, Yuzu doesn't remember where she got the bracelet herself either. As evidenced by the LDS Trio, the means to erase memories most certainly exist in the ARC-V world.

Ruri's own brother believed Yuzu to be her, not upon first seeing her, but after hearing her voice, which is a more reliable indicator than looks. Yuto's reasoning that Yuzu can't be Ruri (because she uses Fusion) is flimsy at best. In a world where Fusion never had any of the negative connotations it has in Kurosaki and Yuto's homeworld, she has no reason to fear it. Yuzu's ace, Bloom Diva, may be a Fusion monster, but its effect is thematically similar to that of Kurosaki's ace: both are monsters that target Special Summoned monsters and gain strength from fighting them. Of course, it must be a happy coincidence that Yuzu's ace features the word Bloom — the second kanji of Kurosaki (presumably also Ruri's family name).

On a more meta level, the frequent cold cuts between Kurosaki and Yuzu when they're in the same scene together hint at a definite connection.
  • A problem with that is that Yuzu has been friends with Yuya and Gon forever, and Ruri has not been missing nearly that long. Yuzu's dad has stated she always had the bracelet. So the most likely option is that Yuzu is a long lost twin sister or something.
    • There's actually no real indication of how long they have been friends. We never get to see a young Yuzu interacting with young Yuya and young Gonzengaka. Likewise, we don't know when exactly Ruri disappeared, or how old she was. And if Reiji could insert Kurosaki seamlessly into LDS and make everyone believe he's always been there (it has to extend beyond the LDS trio—think of all the teachers, classmates, ...), surely it can't be too much of a problem to modify the memories of a handful of people. If Yuzu's had the bracelet the entire time she's been Shuzou's daughter, and Shuzou believes she's always been his daughter, then that logically extends to 'always had it'.
  • Jossed. Ruri was seen in Ep. 38's preview, and just like Yuto in comparison to Yuya, Ruri looks like her, but with different hair (dark blue, like her brother) and eyes (green).
    • Not necessarily. The girl introduced in Ep. 38 actually appears to be Yuzu's Fusion counterpart.
      • Confirmed to be a girl named Serena.
    • Check out this Tumblr post. Be sure to read both the original post (click "Read More") and the additional comments.
      • Considering that Leo specifically called Yuzu the 'fourth piece' he needed, and that Yuri personally confirmed his capture of Ruri and Rin (Synchro Yuzu), I'd have to say this theory is jossed.

Fusion, Synchro and Xyz monsters in the ARC-V world were introduced by LDS
And are not native to their world. They are copies of the summoning styles found in the other worlds, hence why they aren't real. Pendulum monsters are the native summoning of the ARC-V World.

Yuya will gain access to Xyz summoning during a duel against Kurosaki.
  • Jossed

Yuya will overlay Rune-Eyes and Beast-Eyes to perform an Xyz Summon

Yuto, Kurosaki, and the Academia Duelists are Psychic Duelists
Similar to the Arcadia Movement, Academia takes in Psychic Duelists for nefarious purposes. Like Aki and Divine, Kurosaki and Yuto have abilities to inflict real damage, but lack the purple special effects present in Shadow Duels, suggesting that they may simply be Psychic Duelists as opposed to drawing on the powers of Black Magic.
  • It's implied that the Duel Disks can seal people into cards. Sora was warped back to Academia because of his Duel Disk. So, it's possible that the Duel Disks can make the holograms "real".

All the summoning factions involved in the summoning war are unwitting pawns to something.
  • Since the show is called Arc-V, we could suggest there will be 5th dimension - and real evil masterminds will be from there. That dimension will be populated by absolutely terrifying villains - people who don't play Card games at all!

  • We'll also find out that he doesn't even work for Academia, he only goes into the other dimensions to find fun duels.
    • Well, he doesn't work for Academia, but he is looking for "something precious" that was taken from him, heavily implied to be Synchro Yuzu.

The events of Yu-Gi-Oh! GX happened in every dimension.
The Synchro and Xyz dimensions appear to be the settings of Yu-Gi-Oh! 5D's (which is confirmed to take place after Yu-Gi-Oh! GX) and Yu-Gi-Oh! ZEXAL (which is implied to take place after Yu-Gi-Oh! GX). And the Fusion dimension's Academia appears to be an evil version of Yu-Gi-Oh! GX's Duel Academia. There isn't really any evidence that Yu-Gi-Oh! GX happened in the "Standard" dimension but it would be odd if something happened in every dimension except the central one.

There will be a Ritual Dimension
Ritual summon is very (and tragically) underrated; it deserves a dimension!
  • It's possible, but it should be noted that Rituals are different from Fusion/Synchro/Xyz. They are not using Extra Deck.
  • If a Ritual Dimension exists, it is either already completely destroyed or it is completely ignored during the war.
  • Since it's called ARC-V, it five should be the Arc Number of the series.
  • Unless the Pendulum Dimension theory turns out to be true.

"Standard" is the nuclear dimension from which all the other ones spawned
"Standard" is the Yu-Gi-Oh!: Duel Monsters' dimension, where Yugi, king of games lived and Pegasus created the game that conciled ancient powers. This powers, after the return of Atem to the afterlife, when out of control and started to create new dimensions based in the different summonings in order to fullfil their ancient mission of destroying a world (since in "Standard" it became impossible thanks to the pharaon's actions) and with new people who hold mysterious powers in order to fight evil back (the Supreme King, the 5Ds, the holders of the Numbers). The Fusion Dimension is the most closer to Standard since it was the first created (that's why an older version of Yugi appeared in the beginning) and as the other ones where created, they were getting more and more away of Standard, missing their rots with it.

The Crimson Dragon didn't send Yusei back in time, but send him through dimensions, in BBT
Considering that Paradox's actions were causing Yusei's and Judai's respective eras to be erased from existence, I think it's safe to assume this is Jossed. Unless they retcon.

Sora will pull a Face-Heel Turn or be outed as a Mole

LDS knew of the Alternate worlds...
And that is where they got the knowledge of summoning tactics from as well as how they managed to keep that knowledge away from most of the populace (Until Yuya pioneered Pendulums and Sora introduced Fusions to Yuzu and indirectly, Yuya)
  • Confirmed that at least a couple of LDS members knew about the alternate dimensions.

Yuto, Yugo, and Kurosaki will ally with Yuya
And together they will investigate Academia and Yuzu's mysterious bracelet (provided it doesn't separate the group)
  • Yuto kind of out the of picture but you could probably count as allying since he decided to reside with Yuya. Confirmed with Kurosaki as being part of the Lancers.

Academia is connected to the bracelet, and to both Yuzu, Ruri and Kurosaki

Standard will have its name changed to Pendulum Dimension

In the Fusion Dimension, there will be a master of the Cyber Style of dueling who will perform a Heel-Face Turn.
They will start as purely a fusion user, with Cyber End, Cyber Twin, and Chimeratech Fortress Dragons, but will eventual defect to protect the Xyz Dimension, also obtaining Cyber Dragon Nova in the process.

Yuya & Yuto will tag-duel Yugo & "Fusion Yuya"
Yuya and Yuto seem to symphatize with each other, while Yugo is an adversary to Yuto and is aided with Academia. If Academia has a "Fusion Yuya", then a tag duel might be possible.
  • "Fusion Yuya" seems to be Yuri.
  • Jossed. If Yuto isn't Dead Yuto and Yuya did an unintentional Namekian Fusion.
    • I believe that you either mean mean Yoshi Fusion or demon Fusion, not Big Green Fusion.

Yuya, Yuto & Yugo along with their cards are dimensional keystones
The fact that all of them apparently have the same face, as well as have similar ace monsters can't be a coincidence. Furthermore, all of them have the "Yu-" prefix, which usually denote a main character. Not to mention their dragons stats are all the same as the ace cards of main characters (2500 ATK and 2000 DEF).
  • In addition, Yuzu and Ruri might also be dimensional keystones. In the ending for Ep 37, the baddies referred to Yuzu as the possible fourth piece that they're seeking. This also points to there being a Fusion and Synchro counterpart of them too.

Yuya will learn Synchro Summon and Xyz Summon from Yugo and Yuto respectively
Ties in with how Yuya now uses Fusion in tandem with Pendulum. Though depending on what kind of person Yugo is, Yuya might end up learning Synchro from Gongenzaka instead.
  • Maybe sort of confirmed with Yuto...maybe?

Yusho disappeared, because he was (somehow) in the way of Leo's ambition
Reiji stated that the conflict between dimensions is due to his father's ambitions, which seem to entail using dueling as a weapon. It could be that the reason for Yusho's mysterious disappearance is because the entertainment duels that he pioneered may have potentially caused problems for Leo's plan, especially since Action Duels could easily be used as a weapon.
  • Aren't Reiji said that Yusho is working with their enemies?
  • Yusho the Big Bad!

Yuya will obtain Clear Wing Synchro Dragon and the ______ ______ Fusion Dragon
Since Yuya now has Dark Rebellion Xyz Dragon as of Episode 37, there is a possibility that Yuya may obtain Yugo's dragon and Yuri's dragon at some later point in the series.

Goggles are not for nothing!
What if Yuya putting on goggles in tight situations is not just a cute quirk? He is actually hiding glowing eyes underneath!
  • Looks like Confirmed... kind of. In preview of Ep 39 we could see how Yuya's right eye is glowing. And in Ep 25 we saw how blue star on his goggles sparked, when he fought Gongenzaka. That means at least once his eyes were glowing when he wore goggles. Though only one eye (right one) for some reason.

The Fusion Dimension is trying to stir up conflict between the Xyz Dimension and the Synchro Dimension
While Yuto and Kurosaki call Yugo the pawn of Fusion, his statement in Episode 37 (You took away what I held precious), suggests that he may be as much a victim as them in some way.

The Summon Dragons (excluding Odd-Eyes) might have a Numbers-like effect on their users when resonating
In Episode 37, something was DEFINITELY off with Yuto and Yugo in their duel after both their dragons entered the field.
  • If this turns out to be true, then either Odd-Eyes is the Hope/Utopia of the dragons (and thus does not wish to destroy), or Yuya's Pendant acts like the Emperor's Key, protecting him from the harmful effect.
  • Or maybe its Yuya himself who has that power, possibly gained from his Entertainment Duel philosophy.
  • It might be because his dragon transformed. Odd-Eyes Dragon would have had the same effect... but Odd-Eyes Pendulum Dragon does not.

Yugo is searching for the Synchro-Dimension's counterpart of Yuzu.
  • And it would be revealed that she's either his sister or his crush. While Yuto wants to found Ruri, he refers to her as "his comrade and Kurosaki's sister" while Yuto says that she's precious to him, meaning that she's closer to his heart than just a comrade or childhood friend.
    • Almost definitely confirmed, though the way he words it apparently means something closer to outright "girlfriend".

Yuto has merged with Yuya.
Or alternatively, he was absorbed into Yuya's pendant. That blue pillar of light as he disappeared kind of resembled the ones that appear during the Pendulum summoning sequences.
  • Confirmed.

The Fusion-Dimension's counterpart of Yuzu will be a Morality Pet of sorts to Yuri.

The girl from the preview of ep. 39 is not Ruri.
She is Fusion-Yuzu. She is Dark Action Girl, sent to Standard Dimension to capture Yuzu for Yuri.
  • It's not clear yet if she is Fusion Yuzu or Synchro Yuzu, but it's safe to say she is not Ruri.
  • The hair matches the Fusion card frame, so that supports her being Fusion Yuzu. Yugo may have hinted at a Synchro Yuzu with his "what I held precious" line.
  • Confirmed. The girl's name is Serena.

Yuto didn't actually die
Yuzu approaching the scene caused him to teleport away suddenly, along with Yugo.

Yuya and Yuzu having doppelgängers is NOT because of alternative dimensions having counterparts of everybody
The show would get pretty crowded real quick if EVERYONE had look-a-likes. Can you imagine there being four Soras, four Reijis, four Gongenzakas, four Kurosakis, four Leos, heck, even four Sawataris, four Masumis, four Mierus, four Yushos, four Yokos (the list goes on,) all with differing personalities? It would be a mess, not to mention a pain to write. So, to prevent this, it will be revealed that Yuya, Yuzu, and their doppelgängers only have counterparts because they are very special people. HOW they are special is unknown, but at the end of episode 37 the Professor says Yuzu could be the fourth piece that he is looking for, implying that there is something special about her. As for Yuya, considering Yugo is confirmed to be able to talk to (or at least feel,) his dragon, and Yuya being implied to be able to, along with the fact that Yugo and Yuto got Glowing Eyes of Doom during their duel, with Yuya also being implied to get them (in episode 26, the star on Yuya's goggles briefly glows two times for some reason,) it is probably safe to say that SOMETHING is special about them.

Academia captured Yuzu's three lookalikes
And she is the fourth piece.

Kurosaki will attempt to track down Yugo against Reiji's wishes.
The room in which he and Reiji were watching the duel between Sora and Yuto lost the signal when Yugo entered the scene and presumably crashed into the lamppost the camera was on. Kurosaki wanted to go help Yuto, but Reiji told him to stay as to not cause any more commotion since they don't know for certain whether the Synchro Dimension are their enemies or not. Sometime after the duel, Reiji sent Nakajima to investigate and all he could find was Yuto's duel disk, which was left behind when Yuto disappeared. Once Kurosaki learns of Yuto's disappearance, he might try to track down Yugo in order to demand answers about what happened to Yuto.

Yuzu's bracelet is a defense mechanism for the Yu boys.
Should one of them lose to another, they would be absorbed by the other/be destroyed/otherwise remove one from existence. This is why Yuzu's bracelet keeps Yuya and Yuto, and possibly Yugo and Yuri away - it's to prevent any of them from going Highlander on each other. Whether this applies to other doppelgangers or just the Yu boys is unknown.
  • Yuto was defeated by Yugo, but it would appear as if Yuya was the one who unwittingly absorbed Yuto, assuming the theories about those two becoming one are correct. Perhaps Yuya's pendant has something to do with it as well?
    • A slightly different spin— whenever 2 Yus duel, it will inadvertently result in them gaining Glowing Eyes of Doom and going into Omnicidal Maniac mode, being possessed by the dragons. Note how Yuto averted this during the duel with Yuya by negating Odd-Eyes' attack, and he even suggests that he's aware of what goes on in that state. The bracelet's teleport functions as an emergency defuse.

Should Yugo ever go through a Heel-Face Turn, he will help Gongenzaka perform an Accel Synchro Summon.
Aside from the actual cards, to pull Accel Syncro off, you need both Clear Mind, and a high speed. Yugo has a fast bike, but doesn't appear to have a very calm personality. Gongenzaka has a steadfast heart (making Clear Mind easy for him), but doesn't move at all when he does. If Gongenzaka sits in a sidecar or something, they could work together to make it work.
  • Hard to tell if he really needs a 'heel' from what we saw of him/

Dark Rebellion Xyz Dragon will have Yuya learn that Pendulum monsters detached do not go to the extra deck the hard way

Dark Rebellion Xyz Dragon will be used in a duel out of desperation
Yuya will use it when his back is to the wall, and only a pair of level 4 monsters are left in his hand to summon (Skeet Skimmer and Whip Snake perhaps).
  • Desperation, yes. Those monsters, no. Actually was Silver Claw and Cameloose.
  • They are used in episode 45 for such a summon however.

Pendulum Dimension is the fifth dimension.
Because there's no proof that Pendulum Summoning originated in Standard Dimension.
  • Meaning that the pendant could be an artifact from said dimension?
  • The show's Arc Number is 5. Pendulum summoning is the big focus of this show. I'd say it'd be surprising if there isn't a Pendulum Dimension...

Yuya has new Xyz Monsters thanks to Dark Rebellion Xyz Dragon.
When Yuto gave Dark Rebellion to Yuya, it was reacting to his Extra Deck. Due to this Yuya will have Xyz Monsters for the Performapal and Odd-Eyes Archetypes.

Yuto has had Glowing Eyes of Doom before and is aware of them.
In episode 18, during his flashback, Yuto says "I...I don't want to hurt anyone anymore!" While he's saying this, he looks like he's tired and on the verge of tears. At first, these words seem to be referring to his regret for all the fighting he has to do during the war he's in, but in episode 37, when he snaps out of his trance, he says them again "I... don't want to hurt anyone..." Once again, he looks tired. Taking this into consideration, it can be assumed that his words in episode 18 were, instead, referring to the way he gets when he has Glowing Eyes of Doom. This would mean that Yuto is not only aware of his.......problem, but also remembers what he does when he's going through it. The fact that he says "anymore" the first time also implies he has gone through it MANY times before. The real evidence of this, however, comes from episode 37 in the way Yugo and Yuto come out of their respective trances. Yugo comes out of his like someone who just woke up from sleepwalking; confused and asking "Huh?! What have I been..." Probably not remembering anything of their duel past the point of Yuto bring out his dragon. Heck, he may not remember anything about their duel AT ALL, considering he didn't even seem to be aware of his surroundings when he came to. Yuto, however, comes out of his saying the above mentioned words and seems more like someone who just managed to get a hold of himself. He's NOT confused, is still aware he's in a duel, still aware of his surroundings for that matter, and is seemingly aware of what he was doing and what he was about to do.

If the above is true, then it would further explain why Yuto is a Reluctant Warrior. Sure, Yuto probably just hates fighting and hurting people in general, but the underlying reason for his reluctance would be that, every time he duels, he's terrified of losing control. Think about it, you wouldn't want to be dueling much either if you knew dueling sometimes makes you become a crazy person who wants to kill/destroy everything.

The Yuyas and Yuzus are the defense mechanisms of their dimensions.
The reason so far Yuya and Yuzu are the only ones to have alternative selves is because they are defense mechanisms to stop invasions. The Yuyas are the warriors getting glowing eyes and turning destructive to destroy the enemy. While the Yuzus are the defense with their bracelets teleporting people from other dimensions away to save the residents of the current universe.

Academia's Professor is Leo Akaba
Hinted in the second opening when we see the Professor's silhouette in Reiji's glasses. Considering that's Yu-Gi-Oh!, related characters often don't look similar at all, just for example Gozaburo and Noah or Dr. Faker and Kaito/Kite and Haruto.
  • Actually wasn't the Professor talking to Leo, or am I wrong?
    • Probably that was just a subordinate of the Professor.
  • Silhouette in Reiji's glasses doesn't look like Professor.
    • It does. You see the mirrored silhouette of a bald person with one of the glowing eyes being noticeably bigger than the other one, which is the lense that is usually on the Professor's forehead. The next images shows the un-mirrored silhouette's "full" body behind a glass panel, looking at the glowing thing that we have already seen in the end of episode 37.
    • And now it is confirmed, Episode 40 states that Leo is indeed the Professor.

All the Academia Duel Soldiers are Brainwashed and Crazy.
  • Considering the type of show this is, it is very likely Sora and Yuri will end up getting a pass because of that.
    • This is kinda needed otherwise they risk pissing off the GX fanbase.

Yuri's ace monster
The name of Yuri's ace monster will end in "Fusion Dragon" as the other counterparts all reflect their method of summoning: Odd-Eyes Pendulum Dragon, Dark Rebellion Xyz Dragon, and Clear Wing Synchro Dragon.
  • Probably "Yugo Dragon" in the Japanese dub, since all Fusion cards have "Yugo" in their names and Fusion Summon is called "Yugo Shoukan" in Japanese.
  • My guess is that it will require very generic Fusion Materials, so any player can summon it without difficulty (depending on the deck, of course). To makes it even easier, the dragon might even be a Contact Fusion Monster, but that might be a stretch.
    • Alternative Theory: The only way to summon "____ ____ Fusion Dragon" (as that's how it will inevitably be translated), or at least Yuri's preferred way to do it, is to use his opponents monsters as fusion material (a al Super Polymerization). That way, he's literally using his opponents monsters against them. Bit of a stretch, but that seems like the kind of sadistic thing Yuri would do. It should be noted that in #47 (the first and currently only appearance of the thing), Yuzu had no monsters when Yuri had it out, possibly indicating that Yuri used them all up.

Yuzus and Yuyas aren't real.
They're all clones, and each dimension has them. That's why there aren't lookalikes of other characters from the other dimension. The reason that they are clones is because when a Yuya and a Yuzu are together, they provide stability and balance to the dimension that they are both from. However, after Leo's abduction of Ruri, the barriers around the Xyz Dimension fell apart, allowing the Fusion Dimension to invade and destroy them. Furthermore, Leo is attempting to capture all the Yuyas and Yuzus from the different dimensions for some diabolical plan, probably having something to do with monopolizing all of the types of summons.

During the Yuya vs Kachidoki duel...
  • Yuya will gain another evolution in Pendulum summoning, assuming the translation of Reverse Scale Awakening is accurate.
  • He will awaken the dark mode like Yuto and Yugo, and then horrifically beat down Kachidoki. I hope that happens.
  • The theories about Yuto merging with Yuya will be confirmed, and Yuto will help Yuya figure out what he needs to do in order to win, Dark Rebellion Xyz Dragon probably being involved in some way.
  • Yuya will play Dark Rebellion Xyz Dragon.
    • The first is jossed, the third is heavily implied, and the fourth confirmed. The second didn't quite happen as described here, but it's close enough.

Fusion Yuzu's personality will be...
Harsh Tsundere to Yuzu's Sweet Tsundere. I base this on the way she was dressed and her smirking at Sora getting held down by the doctors.

4Kids will censor Kachidoki in a very stupid way
Considering that Kachidoki physically attacks people in the middle of the duel to prevent them from getting Action Cards, there is no way that 4Kids will tolerate that.
  • Preeeetty sure that 4Kids don't exist anymore. EDIT: I stand corrected, it does. DAMNIT.
  • Not sure it really has the Yu-Gi-Oh license though....
  • It's 4K Media now. But it's owned by Konami and probably has a different staff from the older 4Kids. The censorship could still happen but that depends on where it airs and what the FCC regulations say.
  • Since the names of certain characters have already been changed (Ayu to Ally, Reiji to Declan, and Gongenzaka to Gong), I'm sure that censorship will happen.
    • Ah mou, you act as if we haven't had the names changed all the time already. People, 4K Media has censored almost nothing out of Zexal while under Konami. Oh no, Shark wasn't stabbed all the way through. Oh no, they changed the implication so that Kite MIGHT have survived his moon duel. Oh no, they decided that maybe Gimmick Puppet Giant Grinder's... grinding might have been pushing it for a G rated show. All it's been is the really obvious stuff so far. Kachidoki is going to be a hard thing to do, but Arc-V is already looking like it'll be hard to keep G. Also, might I remind you that even before 4Kids became 4K Media, they still showed both Yusei and Kallen/Kiryu beating people up? Besides Declan most of the dub names don't look all that far removed anyway. Gong could be short hand

Tatsuya will duel Reira
Reira has already dueled Ayu and Futoshi and at the end of episode 28, Tatsuya tried talking to him but was ignored. Plus, Tatsuya is the only one of the You Show kids that hasn't dueled yet.
  • If they do, Tatsuya will help Reira to rediscover the joy in dueling, just as Yuya did for him with his Entertainment Dueling. But that won't save Tatsuya of losing.

Yusho and Yoko come from the as-of-yet-unseen Pendulum Dimension
We haven't seen it yet, but there's another dimension that focuses on Pendulum summoning. Yusho and Yoko come from this dimension, and for some as-of-yet-unknown reason they left and came to the Standard dimension. This means that Yuya is, unknowingly, actually native to the Pendulum dimension- hence why Pendulum cards showed up in his deck and he instinctively knew how to use them. Either his parents left before he was born, or they left when he was so little he doesn't remember anything about his home world.

Oh, and another version of Yuya will show up of course- one who really is native to the main character's home dimension, and the "Yuya" representative/incarnation for that dimension, since Yuya himself is the representative/incarnation for the Pendulum dimension.

ARC-V is meant to deconstruct Yu-Gi-Oh series tropes
So far, we've seen the dark side of the following common techniques.
  • Pulling cards out of nowhere (Yuya gets flak for it)
  • The missing parent (Yuya has issues, severe issues)
  • Card Games deciding everything (it turns into something war-like)
  • And most recently (as of this posting), the super powered alter ego (Yuto and Yuya)

How many more common ideas will be deconstructed is yet to be determined.

It was actually Yuto that took control of Yuya in episode 39.
While he probably had good intentions, things didn't go as planned, either because of Dark Rebellion Xyz Dragon's influence, or simply because Yuto may not remember how to duel any other way than how it's been since the Fusion Dimension attacked his homeworld.

Kurosaki will track down and confront Yuya
And considering his personality, it'll hardly be a civil discussion. Kurosaki was obviously upset about not knowing the whereabouts of Yuto, and he'll impulsively assign blame to Yuya and be absolutely livid. However, Yuzu will be there to save Yuya's skin and help talk sense into Kurosaki.
  • Alternatively, Kurosaki will freak out and try to hurt Yuya (Kurosaki does not really care about people who are not his comrades, after all). This will lead to Yuya being possessed by something dark again.

When Reiji's lancers come into play again...
The LDS trio will be made part of the Standard Dimension lancers. Since they are already involved, and fans would be upset if they weren't since they are popular. And they will get their memories back.
  • As long as Hokuto comes back. It is possible that they end up being in the background.

Yuya and his other three look-alikes are Literal Split Personality
Once there was a dangerous person. Maybe even it was some Divine entity - some malevolent God. To stop him, he was divided into four (or five) separate boys, each one represented some part of his peronality, but later they grew into independent people. Since there still was a chance of them merging together back, they were sent to different dimensions. There were also created four maidens with safety devices (braseletes), and it was made sure, that boys and girls are growing up together. That "original persona" is still sleeping in every boy, and can gain temporary control of them, when they are close, or their Dragons are resonating.

Reiji will Ritual Summon in episode 40
Come on, give him an EARTH Ritual DDD already.
  • Jossed, he Fusion Summons and Xyz Summons two new DDD monsters, but no Ritual.

Reiji will convince Yuya to join the fight for their world by promising to help him figure out how to get Yuto back to normal.
Since it seems Yuya and Yuto did indeed merge together, I imagine one of Yuya's main concerns upon realizing this will be finding a way to reverse the process. However, as the tournament progresses and the two gradually get to know each other better and learn how to work together, they don't really figure out much as to how they can get Yuto back to normal since they'd barely know anything about how or why they got fused together. So, once the tournament ends and Yuya learns the truth about why Reiji held the tournament, naturally, he wouldn't want to take part in the fight, and Yuto probably wouldn't want to get involved in it either. However, Reiji, having somehow learned of their current situation, offers to help them find a solution if Yuya agrees to help him in return. With a lack of other options available, Yuya will reluctantly accept the offer.
  • This seems to be jossed at least partially. In the subs Reiji's comment was more that he assumed that Yuya had Dark Rebellion Xyz Dragon than he knew what was going on with Yuya.

Yuya was controlled by the same personality when he first created the Pendulum cards
Watching the first episode you notice that when the Pendulum cards were made, Yuya quickly knew how to use them and then after the duel he forgot. Which people see as a split personality, this was furthered when he used the phrase "I summon my monster servants" which he didn't use besides when he was controlled in Episode 39. Just like in the first episode, Yuya forgot what happened after he won in Episode 39. Or that he acted a lot like Yuto did when he had the glowing eyes of doom in Episode 37. Side note, it probably wasn't Yuto as how did Yuto learn how to Pendulum summon so fricking fast?

Yuya will duel Yugo at some point and add Synchro summoning to his deck by taking Clear Wing Synchro Dragon.

In dub, LDS will be renamed to DDS
Because LDS sounds like official name of Mormon sect, and also reminds of LSD. Leo and Reira also will get names what starts with D.
  • Or because it is too easy for people to link of LSD because of the name.

Yuzu will become a MacGuffin Girl and a Damsel in Distress
Because as awesome as it would be for her to become a badass and plot-relevant character, in Yugioh, female leads are either The Chick and/or The Heart, providing little more then emotional support, Dark Action Girls, or spunky strong side-characters. Considering that Academia is trying to kidnap her, it's only a matter of time before they succeed, forcing a rescue arc. Possibly, whatever the Yuzu's are needed for will go through and a stronger Big Bad will be revealed/unleashed through their power, and Yuya (and possibly some of his counterparts) will save the day. The fact that there's Ship Tease between Yuya and Yuzu would only make a rescue arc more likely.
  • Mai, Aki, Rio... the track record for major female duelists is terrible thanks to the Yu-Gi-Oh! writers. But hey, if they maintain a solid level of badassery for Yuzu throughout the series, then good on them for improving.
  • Actually, given Serena, who is effectively under lock and key and yet still manages to routinely bust out and kick a few asses before being caught again and has managed to flee across dimensions this time, I'm expecting Yuzu and her counterparts to pan out as the Damsel out of Distress trope, or at least cause some problems for their captors (this may be a bit optimistic, but I'd pay to see Yuzu, Serena, Ruri and Rin plan an elaborate breakout).

Serena will use an archtype that feels counter to what Yuzu uses
While they will share Fusion Monsters, it will not be a girly (LIGHT Fairy) anti-Special Summon style.

Instead, it will be something more tomboyish ad straight fusiony. Perhaps the new E-Heroes, considering that she is dressed up in a sort of Slifer/Osiris Red get up.
  • I doubt it will be Elemental HERO. Almost all of the good Elemental HERO cards are from the GX manga and only a few are exclusive from the card game.
  • It could be a DARK archetype to clash with the Melodious archetype.
  • As a possible contrast or similarity, Serena might use a music-themed deck like Yuzu. Serena's name comes from "serenade". Heck, the OCG name of Serenade the Melodious Diva is "Serena".

There is a reason Yuzu has the Yu in her name while Serena and Ruri do not
There might just be something special about Yuzu. After all, even if it one bang, her hair does happen to exist in two colors....and has a Yu name.
  • Her Yu is shorter than the guys' Yu/Yuu, though.
  • Just realized she had a hair color difference as well. But hey, multi-colored hair is a sign of importance in the Yu-Gi-Oh World after all.

Reiji's Lancers will include Yuya and Yuzu
Call it a hunch.

Yuya's next four MCS opponents
After reading the JYC information, the first round had 32 matches and the second round has 16 matches. That means the third round will have eight matches, the fourth will have four, the fifth will have two, and sixth round is the finale. Yuya (as well as Yuzu and Gongenzaka) advanced to the third round, so Yuya needs four victories to win the JYC. So, here are the guesses. Note: Reiji won't duel Yuya in the JYC because he is the host and doesn't participate in MCS at all, and second, he is too old and even if he would participate, he would be either in the Youth Championship or in the Pro Championship.
  • Kurosaki. Probably in the final or semi-finals, but he could also be an early opponent, so Yuya can clarify the confusion as soon as possible.
  • Yuzu and/or Gongenzaka, probably rather Yuzu than Gongenzaka.
  • One of the two LDS exchange students, Dennis and Halil. Possibly even both if he's "lucky".
    • In the third round, Yuzu is dueling Halil and is tagging with Gongenzaka against Halil and Olga, the third exchange student. Yuya is tagging with Dennis against Takeda and Umesugi.
      • Later on in the same round, Yuzu is dueling Dennis.
  • The ace of the Knight School. They do look suspicious.
    • Unfortunately, in the end of Episode 44, all of the duelists from the Knight School has been carded.
  • A member of Academia, who infiltrates the tournament.
    • Not actually infiltrating, and they aren't participating in the tournament either, but Yuya duels the Obelisk Force.
  • If episode 42's name and synopsis is any indication, a battle royale is going to happen.
    • This might be unrelated to the MCS. My guess it would be Reiji vs Serena vs Yuri or Reiji vs Serena & Yuri.
      • Recent magazine scans have confirmed the battle royale part. Yuya will duel two students from the Ryozanpaku Duel School.
  • Due to the Battle Royale in the third round, a lot of of participants will be eliminated at once, so Yuya will participate in less rounds, but he possibly could duel more opponents than usually.
    • Nico confirmed in episode 41 that the Battle Royale round will eliminate half the total number of players like any other round so it is likely that there will be 3 rounds afterwards left which is not less than a usual tournament.

Yuu Sakuragi is a Last Name Basis character
His name just screams for that.

Dark Magician, Dark Magician Girl, Blue-Eyes and Red-Eyes will at least cameo in ARC-V
All of them have somehow appeared in all spin-offs. Dark Magician Girl dueled Judai in the Halloween Episode, and she and Dark Magician appeared in the last duel. Blue-Eyes was used by Kaibaman, and Red-Eyes by Fubuki. Even though Bonds Beyond Time is a crossover movie, it's mostly a 5D's thing and it is related to the 5D's plot; the DM duo and the Malefic versions of the dragons appear there (also we see the original dragons as cards briefly). ZEXAL shows stone versions of the four, with all of them turning "alive".

Sora teaching Yuzu Fusion will bite him in the ass.
Sora explicitly said that he taught Yuzu to take advantage of an opposing Duelist's Fusion in order to further her own Fusion tactics. Well, now we have Academia as the main antagonists... an entire facility's worth of Fusion Duelists. Sora might've just signed his own dimension's death warrant with that.

Masumi will get seriously injured, her soul will be stolen or suffer other unfortunate fate
Kachidoki beat Yaiba to the point he had to be hospitalized, and Serena sealed Hokuto's soul in a card. After that, the last member of the LDS trio got a big target painted on her back, so the question is what, exactly, will happen to her?

One of the duelists from the Fusion World will use Ritual Beasts.
Considering how the show has given us players using actual decks from the game and we've already got one character (Sawatari) playing a Tribe Force/Secret Forces archetype.

Or... someone from this world will use Ritual Beasts, and show everyone that Polymerization isn't necessary for a Fusion Summon.
  • In other words, Contact Fusion.

Nobody of any importance actually knows that Yuya is important.
Let's look at Yuri, Yuya's fusion counterpart. He's sent to catch Yuzu. Fine, dandy, but would he be sent if the Professor had plans for Yuri? Remember Serena has a bodyguard, wasn't supposed to leave her dimension, and she's clearly marked as "important" to Academia. If Yuri is part of some larger plan, he wouldn't be sent out to another dimension where he could be captured so easily. I think it's more likely that Yuri is very talented, and is just seen as an elite prodigal soldier. If other versions of Yuri show up, Academia probably think it's because alternate versions of Yuri are as talented as their Yuri is, and are being sent on the most dangerous missions (traveling to other dimensions) because they're elite.

Even Reiji seems to suspect Yuya of being a plant. When they first see Pendulum summoning, Reiji talks about the possibility of Yuya's father having sent him. Furthermore, look at Sora — we know from what Reiji told Kurosaki that Reiji already knew that Sora was from Fusion. But he didn't apprehend Sora and let him enter the tournament. Why? Isn't the tournament so Reiji can find his "lancers"? Well, he could easily have more then one purpose for the tournamen — finding lancers, as he told Kurosaki, and observing his enemies in an environment he has total control over. Personally, I think Reiji is using misdirection tactics — he's not letting enemy spies (or people he thinks are spies, in Yuya's case) know he's onto them so he can mislead them more easily, spying on them in the process. Stratagem thirty-three in action.

I don't think anybody knows that the Yu's are important. Skilled warriors and therefore powerful weapons or agents or spies, but not important in a cosmic-magical sense.

The Professor isn't Leo Akaba
Everyone is assuming the Professor is Leo, because Reiji assumes so after Serena references the Professor. Serena never confirms nor denies this- she doesn't say anything in response to that. While it's possible that she didn't say anything because he was right, it's also possible that she didn't say anything because he was wrong and she wanted to let him draw his own incorrect conclusions. Either one is possible.
  • Jossed in Episode 41. Reiji directly adressed Professor as "father".

Kurosaki will pull a Big Damn Heroes moment of sorts during Yuya's duel against those two guys from the Ryozanpaku Duel School.
Since he wants to ask Yuya about why he has Dark Rebellion Xyz Dragon, and Yuya's opponents are using Fusion monsters, I wouldn't be too surprised if Kurosaki were to show up, defeat those guys and then drag Yuya off somewhere to talk.
  • In line with the WMG about Kurosaki tracking down Yuya above, it may turn into a nastier Villainous Rescue.
  • Jossed, Kurosaki is fighting the Knight-themed Duelists in a three-on one match, the one who pulls off the Big Damn Heroes moment is Dennis.

There weren't always four dimensions
Instead, they branched off from each other as new summoning methods were discovered. Originally, only Standard existed. Sometime after the original Yu-Gi-Oh, the Fusion dimension branched off of Standard, and that in turn branched into the Synchro dimension and Xyz dimension. This not only explains why no one at all uses Synchro in Zexal, but also the 10th anniversary movie still makes sense.

Sora will eventually be caught between his friendships with the main cast and his beliefs.
Sora's shocked at being asked to capture someone who looked like Yuzu shows he at least cares for the friends he made in the Standard dimension. Since it looks like the main cast might end up in the fight against Leo, Sora might end up facing his friends, which will force him to make a choice, his friends or his beliefs.
  • Take a look at Zexal— the only recurring villains that didn't ultimately get reformed and befriended were No. 96, Mr. Heartland, and Don Thousand. This is in keeping with franchise tradition, so yeah, eventually he'll end up as a good guy, unfortunately.

Yugo will randomly show up at some point during the Battle Royale.
Probably at a time that will either be inconvenient for the main characters or inconvenient for some of the characters from Academia.
  • In before he crashes his bike into the Ryouzanpaku students, inadvertently saving Yuya.
    • Dennis saved Yuya from the Ryozanpaku students.
      • Confirmed, in ep. 47.

Mieru's predictions in 22-23 weren't wrong...they were just at the wrong time.
Listen to how some of them are worded. "I see a great power surrounding you, in the form of a black cloud"? Just over ten episodes later, Yuya gets possessed by Yuto, who certainly makes him powerful if not entirely...right. The "great failure" and the "cunning obstacle that will bind [Yuya] to the ground" will be Yuri; Yuya challenges Yuri to duel in order to protect Yuzu. As a step up from DRXD being immune to OEPD and CWSD being immune to DRXD, the Fusion Dragon will be immune to all of them and Yuya will lose, sending him into a downward spiral.
  • And thanks to that failure, Yuya will try to push his bondaries even further and gain the advance form of Pendulum Summon, a la Accel Synchro.
    • Maybe passing through the limits of the Pendulum Scales. Limit Over Pendulum?

A future episode will reveal that Reiji is a little jealous of Yuya for being Yusho's son
Reiji has stated that he respects Yusho Sasaki deeply, most likely not only for him being the pioneer of Action Dueling, but also because he was indeed a great man; probably Reiji got the chance to meet him in person. After the fiasco with Leo, Reiji internally wishes for Yusho to be his dad.

Yuya's dream from Episode 5 is a huge foreshadowing
Yuya will win Maiami championship. While celebrating, he'll meet his dad (who'll turns out to be evil). And also he'll get some borderline inappropriate hugs from Sora. After that, some calamity will happen and Yuya will fall into dark void.

Serena will duel Kurosaki
Serena will win by giving Kurosaki a Heroic BSOD.
  • Either that or he'll duel Yuzu to similar effect (but still probably win). Either way, he's gonna have to figure out soon enough that his little sister is part of interdimensional counterpart shenanigans.

Yuri was directly responsible for (or the single perpetrator of) Ruri and Rin's kidnappings, and Yuto and Yugo both think the other is Yuri.
Might explain why they seemingly attacked each other on sight the first time they met, when the Synchro Dimension is ostensibly not involved in the war and Yugo's pretty clearly not evil, just somewhat of a tool who thinks the Fusion Dimension is out to steal his name (and Yuto doesn't really like fighting randos). Yuri was also totes picked to kidnap Yuzu on the basis of his outstanding kidnapping resume.
  • Additionally, Yuri disguised himself as Yugo/Yuto when kidnapping their respective Yuzu's. This is so the two are too busy fighting each other to properly find their "most precious thing". Yuri could just wear Yuto's mask and goggles and Yugo's helmet to keep his most distinct features (EYEBROWS) from showing and just bait the two into finding someone who wears those clothes and has the same face as them, without suspecting a 3rd person involved.
    • Yuri did kidnap Ruri and Rin, but he probably didn't disguise himself, as Yugo and Yuto's conflict seems to be more of being in the wrong place at the wrong time, as Yugo's flashbacks show that he personally viewed the invasion of the Xyz Dimension.
    • Confirmed, in fact it seems Yuri did it on purpose.

In a pinch, Yuya will bet some of the Pendulum cards he already has.
His deck already has Pendulum Cards in it, so that will give him a buffer against those that are just throwing random cards into their deck.
  • Jossed.

Yuya will find more Magician Pendulum Cards.
Given that new Pendulum cards are going to be appearing, now would be a good time to introduce more into Yuya's deck.
  • He does not find them, he apparently creates them (either that or he changed some of their effects).

Yuri is already in the Standard Dimension and is participating in the MCS.
Seeing that he was tasked to get Yuzu on Episode 37, he must have left the Fusion Dimension before Serena and Sora did. When he arrived in Standard, he caught word about MCS and that Yuzu is participating in it. From the theory above, he could be very good in disguise. He may bumped into one of the competitors, took their identity and proceeded to the MCS as them.
  • Additionally, the competitor whose identity he stole was Dennis. He attacked the real Dennis, put him into a card, and used some type of unexplained yet device from the Fusion Dimension to steal his likeness. That would mean that the Dennis we've been seeing is actually Yuri. The preview for episode 44 seems to support this theory, as it shows us Dennis getting creepily close to Yuzu, with her obviously feeling uncomfortable about it. As for his reason for helping out Yuya, I've got nothing.
    • If that happens then his plan is going to backfire thanks to Serena, who has her eyes on carding Dennis thanks to seeing him Xyz summoning in his tag duel...and stopped watching the screen just seconds before her actual target, Kurosaki, appeared on-screen.
      • Maybe, maybe not. Yuri is very likely a better duelist then Serena, so if she does target him (which is very possible) and Dennis really is Yuri in disguise, then I see one of two things happening. Either he pulls her to the side and changes back into Yuri to show her he's not an enemy (this scene could be used to show the viewers that Dennis isn't really Dennis, and maybe also to show that Yuri and Serena have a pre-existing relationship,) or he accepts to duel her and mops the floor with her. If it's the former, then Serena will go on her merry way to fine someone else to target and Yuri will be free to continue his plan. If it's the latter, then the duel will be used to show that there's more to "Dennis" then meets the eye (heck, the mere fact that he would be able to beat her is a pretty big red flag,) probably by having him say suggestive dialogue ("oh, are you really sure I'm an enemy?" type of things,) or by having him do some questionable things during the duel, or maybe both! Either way, I don't see Serena being too much of a problem for Yuri.
    • OP here. I have my suspicions on Dennis even if he seems to be a nice guy. An explanation to why Yuri would help Yuya as Dennis, he might be putting him into some false sense of security. When he took Dennis's identity, he may have done some research on Dennis and probably learned that Dennis admired Yusho. I'm willing to bet that if Yusho is actually in or is somewhat connected with the Fusion Dimension/Academia, Yuri may have been informed on what is going on with Yusho. If Yuri is Dennis, I'm guessing that he is not as racist as Sora and Serena since he performed Xyz without a sweat...that or he is an opportunist.
      • Episode 45 reveals that he has Polymerization which is odd since he is introduced as an exchange student of the Xyz course and that he was distracted when he noticed silhouettes of the Obelisk Force.
      • Episode 45 also seems to imply that Dennis, in some way, knows Serena (or, at least is familiar with her deck,) since he inner monologues "Just as I thought" when she summons Moonlight Cat Dancer, seemingly meaning that he anticipated her summoning it. Serena, however, didn't recognize Dennis. So, how could Dennis know Serena, but Serena not know Dennis? Simple, Dennis is in disguise! It's possible she knows him, she just doesn't know she knows him. Now, if Dennis is Yuri then them knowing one another would make sense, because the show has seemingly been implying that all the Yuyas and Yuzus know each other.
    • Though Dennis has Xyz sommoned, he has not used Trapeze Magician to give the final blow, but as a means to an end, so to speak. He let Yuya give the final strike against the Ryozanpaku due and (curiously) switched his Xyz monster for Yuzu's Fusion monster. Just sayin'.
  • Jossed. Yuri appeared from a different dimension in Episode 46.

The eight participants who will be eliminated in the Battle Royale are...
Halil and Olga, assuming that Yuzu and Gongenzaka are able to defeat them and the reverse case doesn't happen; the three Knight duelists who are dueling Kurosaki; Takeda and Umesugi, who will be ass-kicked by Yuya and Dennis; Michio, who will probably be assaulted by both Ninja duelists. Edit: I forgot that the Fisher duelists is also there.
  • Although, it should be noted that the Battle Royale lasts 24 hours, and they are more than just 32 Pendulum cards to collect, so even if you lose, you're not automatically eliminated.
    • Also, none of the duelists bet both of his/her Pendulum Cards, so they won't get eliminated so soon anyway.
  • Spoilers for episode 44 and 45 reveal that the three knights are going to be sealed into cards. So, they won't make it to the fourth round.
  • Spoilers for episode 48 to 50 reveal that Michio will be sealed into a card and that Yuzu is missing. Yuzu disappeared with Yugo somewhere.
  • In episode 47, Halil and Olga are "carded" by Yuri. The cards are currently in Yuzu's possession.
  • Hikage and Teppei are also carded like Michio in episode 47.

The reason why Serena wants to be a front liner is because of her attraction to Yuri
If we assume that Yuri was a front liner three years ago and they might know each other, Serena wanted to follow him to stay close with him.

Kurosaki is a deliberate human artillery weapon
Three points of evidence:
  • How every major duel we've seen Kurosaki in has ended: with Kurosaki using an overpowered one-hit kill on his opponent(s).
  • The fact that he destroyed an entire holographic city during his duel with Sora.
  • The fact that he has the power to make Duel Monsters real, or at least the technology to do so through his duel-disk.
It's possible that Kurosaki trained himself and built his deck specifically for the purpose of doing massive one-hit kills because of the collateral damage this allows him to inflict. Instead of taking out only the opponents he's engaged directly in a duel with, this allows Kurosaki to hit all the enemies in the area. If the duel with Sora had been in the real Heartland, anybody who wasn't evacuated or underground would have likely been hit by one of the bombs Kurosaki dropped in his final move.

So, if the resistance were to build makeshift bunkers, temporarily evacuate a city, or find a sector where they know the Fusionists have set up camp...
  • It's heavily implied that the Duel Disk makes his monster real.

Specific 'advanced advanced summoning' methods are unique to their dimensions of origin
Reiji didn't have any idea what Rank-Up was, and the guy's pretty skilled. So, under that logic, let's assume that similar methods are probably unique to their home universe. Synchro is somewhat simple, with Accel Synchro being unique to it (or perhaps Double Tuning if we go under the idea that Yugo is not really the kind of guy to use Clear Mind), though Fusion is somewhat more of a question. Considering the change in anime Beast-Eyes summoning to Real Life I'd possibly lean to Contact Fusion there.
  • Well, the Numbers War never happened in Standard, so they would have had no concept due to never seeing Astral Force/Barian's Force. And Momentum doesn't seem to have taken hold as a power source in Maiami, so all of its consequences (Zero Reverse, Machine Emperors, Accel Synchro, Yliaster, Z-One) wouldn't warrant someone like Yusei discovering it. Hell, Accel Synchro might even be a product of Momentum itself.

Dennis is Yuya's Johan
Dennis's archetype seems to be based of Entermages, something that sounds similar to Entermate. He comes from the Broadway branch, so his dueling style might resemble Yuya's Entertainment style. We can assume that their similarities will bond them and they become best buddies, similar to Judai and Johan or Yusei and Bruno.
  • And considering his name lacking the obligatory "Jo", it would be revealed that his last name is "Jones".
  • Dennis' last name is actually Macfield. Though he could still befriend Yuya.
    • It's possible that he has a middle or first name with "Jo".

Yuya will rank up Dark Rebellion
He gets cornered again, Superpowered Evil Side pops up, Yuto's dragon is summoned, and he will asspull a RUM card. Much collateral damage ensues.
  • I'd like to hope he'll get a RUM card by plausible means - from Kurosaki (or, less likely but still possible, Dennis).
  • The spoilers for episode 46 heavily implies this. Maybe an almost literal ass pull; he gets this card from Yuto's soul.
    • He pulls it out of Yuto's soul's ass?
    • Jossed. At least for episode 46. According to the preview, it looks like Yuya will summon Odd-Eyes, then use the two new Magician's effects to give Dark Rebellion a Level equal to its Rank and then makes it equal to Odd-Eyes's, so he can overlay them.
  • Serena carding Dennis may be a trigger for this.
    • Jossed.

Kurosaki and Sora will be forced into a temporary Enemy Mine of sorts in order to help stop Yuya's Super-Powered Evil Side in one of the upcoming episodes.

Yugo and the rest of the Synchro Dimension have been Locked Out of the Loop by Academia
When there's a faction that uses Fusions and their enemies call you a "Pawn of Fusion", the usual response is denial that you're part of the faction, same name as them or not. Yugo was only focused on Yuto getting his name right but not the "Pawn" part of Yuto's accusation. Yugo might've been tricked by Academia to unwittingly be their distraction and he is unaware of the war because of that. Either by giving him incomplete information about the dimensions (like leaving Fusion Dimension out) or by falsifying the Xyz Resistance actions (Which one WMG above says to a similar effect). The rest of the Synchro Dimension could also be tricked into thinking there's no war. Which is why they don't seem to have a presence in the series yet. Academia is keeping their presence hidden to allow themselves to surprise attack Synchro.
  • This seems likely, and I would not be surprised if Yugo showed up at the end of the tournament seeking help because Academia finally invaded the Synchro Dimension.
    • That, or Academia has already invaded the Synchro Dimension, and somehow pinned it on the Xyz Dimension. Yugo suggests he doesn't know anything about the Fusion Dimension, so he may not even be aware of Academia's existence.

Let's speculate about Ruri!
As Yuzu's Xyz counterpart, we all know that she'll have her same face and body structure, but Serena has confirmed that hair color, hairstyle and eyes are different. Let's guess about her appareance!
  • Ruri will have a dark hair color to match the Xyz black cards, maybe black or a very dark blue with gold eyes match the Overlay and her brother's. Her hair will be short and let down, to contrast Yuzu's pigtails and Serena's ponytail.
    • While the series sets up the idea that she's a Damsel in Distress, this will actually be subverted, and her Establishing Character Moment will prove her to be a Damsel out of Distress. (Hahaha. Very funny. But one can dream, right?)
    • I support you in your dream. But alternatively, Ruri is a Broken Bird Action Girl for the war and all the crap she had to endure.
    • On another tangent, the only reason she's in the Fusion Dimension is because she believes Kurosaki was the one kidnapped by Academia. As the MCS unfolds, she continues to attack unwitting civilians in a city in the Fusion Dimension, hoping to extract any sort of intel that might lead her to her brother, though as of yet her results are fruitless since she hasn't encountered anyone from Academia who could answer her questions, that is until they catch wind of people disappearing and a powerful Xyz Duelist in their midst.
    • Or she is a girlier, softer version of Yuzu in contrast to the dark and tough Serena.
  • She uses the Strike Serpent deck, as a contrast to Kurosaki's Raid Raptors. Instead of delivering Death from Above, they ambush their enemies with Dig Attacks. May keep the mechanical theme (especially with drills) and the DARK attribute, since she's a part of the Resistance and would keep the "Dark Rebellion" motif, but will obviously be Reptiles instead of Winged Beasts. The Main Deck monsters will share the name "Viperidae," while the Xyz Monsters will have the word "Cobra." She's also capable of Rank-Up. She might have a serpentine bang in her hair, similar to Kurosaki's "feather," in reference to the deck.
  • She'll be the last Yuzu to appear in person, near the end of the first half (Episode 60-79). When they find her, she'll be traumatized from all the imprisonment or experiments. It'll take Yuto to cheer her up again.
    • Confirmed, at least the part where she's really the last one to appear.
  • Ruri has blond hair with red streaks, because she was turned into card during Fusion invasion, and this card is... Entermate Trump Witch! What a surprise!!!
    • She's not turned into a card, as stated by Yuri.
  • Ruri may have blond or orange hair to follow a particular pattern. It seems females' hair colours matches a male character of a random dimension. For example:
    • Rin has Yuya's light green hair shine (while not his normal hair colour, he has a light green 'shine' that matches Rin's hair colour
    • Serena blue hair (either her light blue streaks or her base hair) matches up with Yuto's blue (or arguably Yugo's dark blue).
    • Yuzu's purple/pink matches with Yuri's pink highlight
    • Leaving Yugo (or Yuto) remaining. So either Ruri will have blonde (Yugo), navy blue (Yugo) or lavender (Yuto) hair colour
The Berserker Modes are because of their Dragons
In episode 43 when Yuya Xyz summoned Dark Rebellion, he saw Dark Rebellion and nearly went into Berserker mode. I think that means all the Yus' Berserker Modes are due to their Dragons. Which explains how Yuya knew how to Pendulum and Xyz summon in his split personas. The Dragons would know how to summon themselves. My theory is in episode 1 Yuya was under Odd-Eyes' control explain why Yuya isn't crazy. While in Episode 39 Yuya was under Dark Rebellion's control.
  • The reason why Odd-Eyes doesn't turn Yuya into Berserker mode is because it recognize it as its proper owner, unlike Dark Rebellion, which can tell Yuya is not Yuto despite the whole spiritual fusion thingy. Which leads me to thik that the only reason why Dark Rebellion let itself be summoned by Yuya via possesion is because it recognized some part of Yuto in him.
    • That doesn't explain why Yuto and Yugo enter it while in their duel, since they were in their respective owners' control.
      • Possible explanation - Yuya's pendant is actually a safety device that supress Odd-Eyes' control (it's sparkled when Yuya was presumably under OE's influence). It doesn't work on other dragons, that's why Yuya lost it, after absorbing DRXD.
  • Also, the dragons react to each other and turn their Yu-sers into Berserks. Notice how Yuya and Yuto react when they got their dragons in the field in episode 36; I bet they would have go Berserk if it weren't for Sora being forced back to Academia to keep them grounded, which makes me think that the Yus can only snap out of it once the duel is over or by help of external force, like Dennis did in episode 43 for Yuya and Yuya did for Yuto in episode 37.
  • It could be some sort of defense mechanism, such that when a major threat is perceived, they take over and respond aggressively to eliminate it. Furthermore, the dragons all see each other as such threats, and thus are highly reactive because they believe their respective Yu is in danger. Since Yuto knew Yuya was Not So Different, he went out of his way to defuse the situation in the duel so the dragons wouldn't take over. However, when Yugo shows up, the danger is real this time, and when Clear Wing comes out, he can't stop Dark Rebellion until Yuya intervenes. Furthermore, the reason Dark Rebellion takes over Yuya instead of Odd-Eyes in Episode 39 is that, due to its experience with Yuto, it has an understandably itchier trigger finger and is more reactive to perceived threats, and overbearingly jumps to protect Yuya because of Yuto. Yuya hasn't been constantly in mortal danger, so Odd-Eyes is more passive. This also supports why Dark Rebellion is cooperative with Yuya even after he resists its influence thanks to Dennis.

In the end, Leo is an Well Intentioned Extremist
What Leo meant when he said to unite the worlds/dimensions was to pool the strength of all the dimensions against their true enemies. The Ritual Dimension, that loathes the other dimensions and has been arming itself. This all being meta subtext for how the franchise ignores Ritual summoning.

Leo Akaba will use Super Polymerization to unite the dimensions.
And he gave the card to Yuri to complete. Related to this
  • Alternatively, Academia has already unlocked Super Polymerization on a widespread level, and that was what Sora was about to do right before he was called back to Academia. He was saying he was going to show them "true" fusion summoning right before being called back...

Fusion Dragon has various Fusion forms, like Elemental Heroes or Neos
Fusion Dragon can merge with any extra deck card (Fusion Dragon + 1 Xyz Monster, for example) to form a new, more powerful Fusion Dragon. Which is how Super Polymerization is useful to Yuri and he's the only one who can bring out its power, as presumably he has the same card making abilities as Yuya.

The dragons are real!
The cards posses the spirit of each dragon and when summonend they ''actually' become real; the Solid Vision in Action Duels just diguises them and that's why Yuya never notices the difference. That would also explain why they seem to have some sort of consciousness when reacting to each other or possesing their users, they actually have a mind of their own!
  • For the consciousness part, it is mentioned since Duel Monsters and even in the very first chapter of Magic&Wizards that the cards have their own hearts and have some sort of personality.
  • This isn't that new from the original series alone, we had Dark Magician, Dark Magician Girl, Blue-Eyes, Red-Eyes, Kuriboh and the Egyptian Gods. 5D's which had the same director had the Signer Dragons, which were said to be real Dragons at one point that changed into cards.

Michio will be helping out during an "I Know You're in There Somewhere" Fight against Yuya in episode 46.
Since he suddenly seems to be relevant again, I suspect that he will probably be one of the duelists helping Gongenzaka to try to stop Berserk Mode!Yuya.
  • Apparently jossed. Michio is busy dueling Halil and Olga. This role will be given to Mieru, however.
  • Jossed on the fight but Confirmed that he helped out in trying to get Yuya out of his Berserk Mode.

Just for fun.

The Ritual Dimension will have a lot Mythology Gags about the Duel Monsters series
Fusion Dimension and GX, Synchro Dimension and 5D's, Xyz Dimension and ZEXAL. Duel Monsters is the only series where more than three duelist used Ritual Monsters (Atem/Yuginote , Kaibanote , Jonouchinote , Pegasusnote , Keithnote , Mask of Lightnote , Noahnote , the Big Fivenote , and Dartznote ). Even though Standard has some references to Duel Monsters, there also many other references to other series, so the Ritual Dimension might have a bigger connection to Duel Monsters. Especially, the video games from the Duel Monsters era had very special Ritual Monsters, with many of them being Normal Monsters in real life.

Yuri can use Berserker Mode
Well, since he's another dimentional counterpart for Yuya, this seems to be a given, BUT Yuri's real gimmick will be that he can enter Berserker Mode at will and remain conscious while in it. That's why he seems to be working directly under Leo as his biggest assert and, if he's send by him to go after Yuzu, he was most definetely send to capture Ruri and Synchro Yuzu.
  • Interesting thing to note - in latest episode Yuri was walking around, accompanied by silhouette of his Dragon. Maybe he is actually constantly in Berserk mode? Maybe we haven't even seen his real personality yet?

Tatsuya is a duelist from the Ritual Dimension
Aside that his blue hair might be a hint, he is the character who explained how Ritual Summon worked, and of course he knows the basics like Flip Summon. But why is his family here? It's because it is the first dimension Academia conquered, which would explain why he has heared about Fusion Summoning, and his family managed to escape from the war into Standard. Yuzu being the fourth piece means that she is the fourth girl to be captured, since Serena doesn't need to be captured and belongs to Academia all along. However, as a contra argument, Ritual Summoning is nothing special in Standard and LDS doesn't even have a special course about Ritual Summon and you can just learn it in the composite course, so it isn't monopolized like the rest.

The Fusion Dimension isn't the world of GX, it is Z-One's timeline
At the moment we assume that the Fusion Dimension is the world of GX because Academia is the main setting and they use Fusion Monsters, like in GX. Similarly we assume that the Xyz Dimension is the world of ZEXAL because Heartland is the main setting and they use Xyz monsters, like in ZEXAL. We assume from that, that the Synchro Dimension is the world of 5D's. Back when ZEXAL was airing, it was a common theory that, because it didn't have many ties to the previous show and because we didn't see Domino City in any capacity, that it was from a different dimension then the first 3 shows. The 4 dimension plot point would seem to strengthen this idea, but we know thanks to the Bonds Beyond Time movie that the original show, GX, and 5D's share a universe. However, we know that 5D's has its own alternate dimension, Z-One's future.

Maybe in Z-One's timeline once Synchro Monsters became more widespread, the people of Academia became more worried about them and blocked themselves out from the rest of the world. After the Meklord Emperor Genocide, because they refused to use Synchros, they were spared destruction, and continued to use Fusions as the dominant form of summoning. Also because they blocked themselves off from the rest of the world, Z-One and his gang wasn't aware of their existence. After the end of 5D's, the people of Academia would have been the sole survivors, meaning Academia would have been the only inhibited location, and Fusion would have been the only advanced form of summoning. Also thanks to Z-One's experiments, they would have been able to figure out how to travel between dimensions. When Leo saw that their were other dimensions that still thrived, he would have wanted to bring his dimension back to glory, leading to his ambition and starting wars with the other dimensions.

Yuri has indeed infiltrated Standard undercover already. But not as a MCS participant. He is in Sakuragi's squad
Check this picture. See the guy behind Yuu Sakuragi? Purple hair. Pink clothes. Long bangs to hide eyes and atrocious eyebrows. It would be really funny if Yuri was hiding all this time right under Reiji's nose!
  • Jossed.

With the release of Red-Eyes Fusion and Black Dragon Archfiend
A Red-Eyes Duelist, probably from the Fusion Dimension will appear.
  • I have the feeling that Yuri will use a Red-Eyes deck. I wondered why Red-Eyes support is coming in Clash of Rebellion (CORE) instead in a Structure Deck like Blue-Eyes and Black Magician; the new Structure Deck has been announced recently. Considering that Yuri will probably duel in the episode 47, his cards might be featured in CORE, either that or in the next set. Red-Eyes is becoming a Fusion archetype, and other cards of Jonouchi have been appeared in ARC-V (Battleguards, Panther Warrior). Also, Red-Eyes has been appeared in all previous series (originated in Duel Monsters, played by Fubuki in GX, stolen by Paradox in BBT which is basically a canon 5D's movie, is a statue and spirit in ZEXAL), so it's not unlikely that Red-Eyes will appear in ARC-V at all.
    • However, after watching episode 47, I start to doubt that since it appears that Yuri won't duel in the near future, so he probably don't play Red-Eyes cards.
  • If a Red-Eyes duelist ever appears, he/she is not likely from the Fusion dimension, since Red-Eyes Metal Flare Dragon is an Xyz Monster.

The Yuya's are meant to destroy dimensions while the Yuzu's are meant to create dimensions
Leo Akaba is planning to "unite" all the dimensions together. He is capturing the Yuzu's so he can to bend them to his will and create his ideal, unified universe. The Yuya's are being tricked into fighting each other to find their respective Yuzu's; so they bring out the power of the dragons and merge to destroy everything. Yugo and Yuto during their fight and suddenly got glowing eyes, was rambling about destroying everything and Yuya's new magicians called "Destruction" and "Creation" Magicians, are hints to this.
  • To support this, the Destruction Magician's face resembles Yuya's and the Creation Magician's eye resembles Yuzu's.

Dennis is from the Fusion Dimension
In light with Episode 45, Dennis reveals to have Polymerization in his deck despite being introduced as a student taking the Xyz course and that he paused when seeing silhouttes of the Obelisk Force. With the possibility that he may not be Yuri, this WMG can go to various points.
  • He left the Fusion Dimension as a refugee as he may not want to be involved in the Interdimensional War.
  • He is one of the Fusion agent and is studying to use the enemy's way of attack against them.
    • Bonus points if he knows/is an associate/works under Yuri.
  • Counter theory: He just a person in Standard who is interested and is practicing both summons.
    • So, he would be a Red Herring then? I hope that's not the case, but you never know.
  • One and three are Jossed. Two is Confirmed..

The MCS arc, unlike the arcs of the previous series, will have a Bittersweet Ending where:
Bear in mind, taking inspiration from previous WMGs, Yuya's rampage and the attacking Obelisk Force will distract Reiji from Serena and Yuzu, who will be attacked by Dennis, who was being impersonated by Yuri, who had sealed Dennis offscreen in a card, since he had the traits Yuri would need to infiltrate the tournament, avoid Reiji, and know how to deal with his task (Dennis being a fan of Yusho meant Yuri could get to know how Yuya duels in person, which he would want to know, since he most likely knows all about the interdimensional counterpart thing, and do the same with Yuzu). Yuri will fight both Serena and Yuzu at the same time, defeat them, and successfully bring them to Leo, who will do god-knows-what to them, Ruri, and Yuzu's Synchro counterpart to 'unite' the 4 dimensions, likely to begin creating his ideal universe from the previous WMG involving the idea of Yuyas destroying dimensions while Yuzus create them. The tournament will continue from here, but with a definite melancholy feel, ending with Reiji having found his Lancer candidates, likely including a BSOD-suffering Yuya, and begin training them to prepare for a full-front assault on Academia, and the next arc will begin after a Time Skip.
  • Seeing as over a dozen people were carded and Yuzu is MIA, yeah, I'd say it was.

Dennis is actually a part of Sakuragi's squad
Judging by the fact that he has Polymerization in his deck, Dennis can use both Xyz and Fusion summons, and since the show has been treating the ability to use multiple summoning methods as something special, you would think Dennis would be on the top of Reiji's list of potential recruits for protecting the Standard Dimension from the Fusion Dimension. The reason we don't see him with the others is just because he's been having too much fun with the tournament to want to go to the "squad meetings." Inevitably, he will be chewed out by Yuu Sakuragi for playing around with Yuya and Yuzu when he should have been looking for signs of the Obelisk Force and dueling them.
  • Jossed. He is a Fusion agent.

In the 2nd Sora/Kurosaki duel and the Obelisk Force/Yuya duel
  • We'll either see new Frightfur/Des-Toy monsters, or see the anime debut of Frightfurs Tiger and Wolf.
    • Tiger confirmed.
  • See the appearance of the first new Ancient Gear fusion monsters since Ultimate Ancient Gear Golem, or we'll get to see that again.
    • Yuya one shots them with his new dragon Odd-Eyes Rebellion Dragon.
      • Yuya one-shotting them with Odd-Eyes Rebellion Dragon is confirmed.

Yuri will seal Halil and Olga in cards in episode 47
In the preview, we see the two in the Antartic area, and Yuri's says "Younote  are in my way." He possibly refers to those two.
  • Absolutely confirmed.

Yoko's um.......interest, in Dennis, Michio and others will not make it into the dub
I don't normally hate on dubs, but I don't think a dub aimed at children can have a Cougar on it.
  • Unnecessary 4kids edits, sometimes there are exceptions.
  • I don't think that children would think in that way.
  • It's really more of her fangirling than anything related to cougars.

Dennis is a Long Distant Relative of Sideshow Bob.

Yuya would let Yuto take over his body just like how Yugi does it for Yami/Atem.
However, Yuya does it out of despair due to the events happening during the tournament and his ideals being repeatedly crushed. Yuto himself opposes with the idea and tries to persuade Yuya not to do so but ultimately fails. This situation is highly unlikely to happen but given Arc-V's unpredictability, there may be a possibility.

Yugo will accidentally bring Yuzu to the Synchro Dimension while trying to protect her from Yuri.
Of course, Yuya and his allies won't find out about this until later, and will likely assume that she ended up being captured by the Fusion Dimension. During the next arc, Yuzu will be learning more about the Synchro Dimension and Yugo's motivations while trying to figure out how to get back to the Standard Dimension. The Fusion Dimension will then likely begin an attack on the Synchro Dimension, with Yuri having figured out that that is likely where Yuzu is and hoping to lure her out.
  • Eh, Semi-Confirmed, as Yuzu accidentally got teleported with Yugo when Yuya showed up, but seeing how easily Yugo traverses dimensions and how all of the dimensions have technology that allows them to go to another dimension, I'm fairly certain that Yuzu will be able to contact Yuya fairly quickly.

Yuya will get carded
(Related to the WMG 2 spaces above) ...But to the surprise of the person who cards him, his physical body stays. Yuto's soul will take over the vacant body and get back Yuya's soul.

The reason why Dennis was able to talk Yuya out of his Berserk Mode is because he has done it before.
He seems to know Yuri personally (based on how he greeted him when the latter arrived). He may even have been a witness to one of Yuri's Berserk Mode episode before.

Ruri and Serena are in a similar situation to Yuto and Yuya
While Sora does imply that Ruri might had been sealed in a card, it does seem unlikely considering her apparent resemblance to Yuzu and Serena and the importance they have (That and lying doesn't seem out of character for Sora). It is possibly that Ruri and Serena might had been merged together like Yuya and Yuto did (whether willingly or not). This might tie into the "Yuya and Yuzu use to destroy and create the universe" WMG above with the Evil plan requiring the dimensional counterparts merging into one.
  • Technically Sora did not know for sure, he just assumed that she was in a card.

Yugo will become fused with Yuri.
Since Yuto is already fused with Yuya, (and this appears to make them more powerful), Yuri will defeat and absorb Yugo to make himself more powerful. I hope it doesn't happen, but I have a feeling it will since how dark everything is getting.

Clear Wing Synchro Dragon is in fact capable of time travel.
And at some point, it will bring Yugo and Yuya to the Standard Dimension three years in the past, and this is how Yuya (and the viewers) will learn how and why Yuya's father disappeared.

Serena and Yuzu will pull a Fusion Dance
With the result being Yuzu being a part of Serena. As opposed to the reverse. It might be related to the "Serena and Ruri merged" theory I posted previously.

Yuya will lose his rematch to Reiji
Since Yuya is pissed of for several reasons, Reiji will calm him down and proves that he is still above Yuya's league.

Yuya will use Odd-Eyes Saber Dragon as an attempt to avoid Xyz and Fusion monsters
Considering Academia and Berserk Mode, I don't think Yuya will want to keep using them. Perhaps Reiji will duel him to give him a reminder that it's not the card type, but the evil organization that is the cause of both problems he's seeing with them.
  • Based on episode 50 and the previews to 51, jossed.

Yuzu will learn Synchro Summoning.
Since she seems to be spending time with Yugo after they were teleported away.

Yuzu will learn how to ride a D-Wheel
Related to how she will learn Synchro Summoning.

Dennis and Yuri are friends.
Difficult to really tell at this point, but Dennis did seem to be rather comfortable around Yuri. Keep in mind that Yuri is a guy who has no problem with sealing his own comrades into cards. It's not hard to imagine that if any other person from Academia, who knew any idea of what Yuri is capable of, was assigned to work with Yuri they would show some signs of fear towards him and try their very hardest to not provoke him (as Yuri is not only dangerous, but also seems to be rather impatient,) yet Dennis so far has shown no fear towards him, and even expressed irritation at having to wait so long for him, albeit in a seemingly playful/joking manner. This easiness around him doesn't seem to be just because Dennis is ignorant about what type of person Yuri is, either, since when Yuri threatened to seal members of the Obelisk Force into cards, nothing is shown to indicate that Dennis found this behavior surprising. And, when Yuri steps up to duel Olga and Halil in episode 47, you can see Dennis frown. Now, it could have meant nothing at all, but it is also possible that it meant that Dennis knew what was about to happen next: a one-sided, brutal duel that ends with the two bystanders getting sealed. So, it seems that Dennis, at least, has worked with Yuri before.

To add to this, Yuri and Dennis share a defining feature, their smiles. Dennis is rarely shown not smiling, and all of his monsters shown so far have had big grins on their faces. Yuri is the same in that he's almost always smiling, episode 47 is even called The Cold Smile of Yuri. Some of their mannerisms seem to be the same, too. They both seem to have a habit of putting their hands on their hips and use the same Japanese pronoun "boku." They also act a bit similar in their respective duels with Yuzu; Dennis praises Yuzu for her skills as a duelist, while Yuri mockingly praises her for her ability to keep away from him for so long.

Alternatively, Dennis and Yuri are brothers. Fairly unlikely, but something to keep in mind is that Yuzu has a counterpart with a sibling, so it is possible that one of Yuya's counterparts has a sibling, too.

Ruri and Rin will share the same seiyuu, and it will be the other member of P☆Cute
Yuya and Yuzu share the same seiyuus with their Fusion counterparts. Yuto and Yugo have also the same voice (actually not, their seiyuus are twins, but they sound almost the same). So, if we assume that Ruri and Rin won't get twin sisters as seiyuus, they get the same seiyuu to fit with the ARC-V theme. We know that P☆Cute is created exclusively for ARC-V and the pop duo look a lot like Yuzu and Masumi. The members of the duo are Rin Aizawa and Arisa Kiyoto, but by their Stage Names Ruri Shirosaki and Masumi Anzu/Yamitsu/Kurashitsu, respectively. Arisa Kiyoto voices Masumi Kotsu, who looks very similar to the other Masumi. So the band is seemingly also created to foreshadow the plot and the casting. And there is no coincidence that Ruri Shirosaki has almost the exact same name like Ruri Kurosaki or Rin Aizawa sharing the same first name with Rin.
  • Jossed, as Rin is voiced by Sarah Emi Bridcutt. We don't know if Ruri will be voiced by her as well.

Yuri will seal Dennis into a card.
Probably because of You Have Failed Me or You Have Outlived Your Usefulness reasons.

Yuya's pendant has the able to release people in cards.
Judging since its first appears, his pendant changed his cards to Pendulum cards, created cards such as Odd-Eyes' evolutions and Yuya's two new magician and seems to have a connection with Yuya and his counterparts. I won't be surprised if this happens.

Jack and Crow
will teach the heroes how to duel better Yuya might learn Synchro Summoning or Gongenzaka learns Double Tuning by Jack.

Sakuragi will have a bigger role.
After building him up as a strong duelist, giving him a unique design, and not sealing him away with the others of his group, it seems pretty obvious that he'll return. What I'm thinking is, he'll run into a one of the factions and learn their summoning method (I'm thinking Yugo), and/or he'll get major character development to make him more of a Lovable Coward.

Leo Akaba's Plan is directly inspired by Yubel's plan and intends to play out the same way
12 Dimensions, 12 universes, and one villain set to merge them into one.

The new arc...
is actually based on the Manga continuities of Yu-Gi-Oh! GX, Yu-Gi-Oh! 5D's, and Yu Gi Oh ZEXAL and as such characters (Koyo Hibiki, Sect Injun, Cologne) and cards (such as the Duel Dragons and Legendary Planets) from there will show up in ARC-V
  • Aside from the cards, that would be problematic in the long run. Why an anime crossover with manga counterparts? That would make no sense. Most people are familiar with the anime of each series, especially since they've already set up a continuity with the first three series.
    • However using the Anime continuities would also be as problematic as it is clear that the other dimensions are based on the setting of the past shows (especialy with the Xyz dimension), even though ZEXAL had no direct contiguity from the movie there is also Yugo, who seems to come from Neo Domino City, and Academia, which is rather obvious. Using the Manga continuities would allow new possibility and avoid the Continuity Snarl that happened with the other Dimensions (as unlike the Anime continuities, neither of those were directly tied to each other)
      • It's most likely that Academia, Neo Domino City and Heartland City are alternate counterparts to Standard's. ZEXAL showed a bit of connection to the other series when they showed the statues of iconic monsters like Blue-Eyes or Neos. Also, how could the Action Field Future Metropolis Heartland City look exactly like the Xyz Dimensions's Hearland City if it was already destroyed three years ago? Either Reiji used the teleportation device to go to the Xyz Dimension before the war happened and then he modeled the card after the city or the Action Field is based of a Standard version of Heartland City.

Jack and Crow were manipulated by Academia into attacking Maiami City
This is probably a false rumor, as the setting is not in Maiami City anymore.

Academia might find a way to control people like the Orichalcos, Light of Destruction and Barian Emblems
And would use this power to pit the denizens of the other 3 dimensions against each other and then eventually sending his own forces to pick off what remains.

Rin and Ruri are sealed in the Fusion Dimension Machine
It seems rather obvious that Yuzu's counterparts are very important and we have no idea how the machine works beyond sucking in cards, but I think that given that those 2 are The Ghost at this point and that the machine might need a point of reference for the other dimension (that and the WMG above about Yuzu representing Creation), it's likely that Leo's plan requires the machine to absorb Yuzu and her countperparts. The reason why Serena didn't suffer this fate is wither because Leo didn't notice that she and Yuri were the Fusion's equivalents of Yuzu and Yuya or because he's saving her for until he knows the other three are absorbed (and is likely trying to keep her in the Fusion Dimension for that same reason).

About Dennis after the reveal.
  • His true ace, the Fusion, will be some sort of Evil Sorcerer
  • Yuya will end up with his old Xyz either taking it or being given it.

Sora and Yuya's second duel.
  • Yuya will bring Sora back to the light
  • Sora will start to change, but then get a Heel Face Door Slam.
  • Yuya will go berserk again and crushes Sora and shocks him. Bonus points, if he's using his terrifying Odd-Eyes Rebellion Dragon.
    • Jossed. Yuya does summon Odd-Eyes Rebellion Dragon, but the duel is ended by the Battle Royale ending with no winner.

Jack and Crow are misunderstood
Jack and Crow aren't invaders, they were just transported into Standard maybe by accident and Reiji not taking any chances sent the Lancers to duel them and they just counterattacked.
Yugo personally knows Jack and Crow.
And the whole reason why Jack and Crow go to Standard in the first place is because they're looking for him.
  • Going with that, depending on how old they are here, Yugo will be revealed to be Yusei or Jack's son.

Jack will summon Red Nova Dragon
Or even better get an upgrade...

Crow will get new Blackwing monsters
Or even better, a new Synchro Blackwing. Or maybe just one of the manga ones.

People sealed in cards are released by Normal Summoning them on a Duel Disk
Hey, they get turned into Monster cards.
  • Or it just creates holograms that show how the people are suffering

Sora will be meeting Ruri and Rin sometime in the near future.
If word somehow reaches him that Yuzu is missing and presumed captured/carded by Academia, he will decide to investigate on his own to try to find out whether Yuzu really is somewhere within Academia. Instead, he'll end up finding the place where they're keeping Ruri and Rin.

What if Reiji left the 2000 point penality as a test.
Maybe he left that stupid thing as a way to see if they have the stuff to survive. Against the Academia, he needs the strongest he can get and maybe he left it as a way of cutting the fat. We seen he's willing to let people get carded with his first Lancers and the Ninja bros.

The darkness inside Yuya...
It's actually the Ritual counterpart of Yuya. His dimension was destroyed by Leo, and his soul found refuge in Yuya.
  • And the Ritual counterpart is based of Atem.
    • Wouldn't a better one be Yugi? All the Yu's excluding Yuya have been opposites of the protagonists of the series their dimension is based on. Atem acting aggressive isn't out of character for him, at least not in the early series. But Yugi, the kind, and compassionate character is the perfect opposite of the aggressive, rage filled Berserk Mode

Leo Akaba is sexist
After all, Serena is the only female member of Academia we have seen so far (up to and including episode 49) and the Professor denying her request to be part of the invasion force could be a Stay in the Kitchen attitude.
  • Can't recall, but weren't some of the Mooks female? Either way, I doubt it. More probably it's because she's an Apocalypse Maiden.

Arc-V will become a Crisis Crossover with all previous continuities.
On top of the fact that all the dimensions shown so far have aesthetics of all the previous anime series, the Xyz dimension referenced Heartland by name, and the third opening sequence shown what appears to be the silhouette of Jack Atlas with his signature card behind him.

The Synchro Dimension is not as nice as it appears to be
Deconstructions and all.
  • True, the Synchro Dimension is even more classist than Neo Domino City at the beginning of 5D's.

Dennis will become a Double Reverse Quadruple Agent throughout the series.
Either he'll end up Becoming the Mask, already has an alternate goal in mind, or just can't decide which side to work for.

There will be future Pendulum Magician pairs that assist with Synchros and Fusions.
Granted, this one's really kind of a given really, considering we got ones that assist with Xyz summons, and the increased focus on all summoning types.
  • As of right now, Synchro Magicians have been confirmed, with one being the first Pendulum / Tuner monster.

If Arc-V really does become a Crisis Crossover, and Yugi makes an appearance, we will get Fusion Monsters based on fusing Yugi's Dark Magician and Dark Magician Girl with Yuya's Pendulum Magicians.
They will be named something along the lines of Dark Pendulum Magician and Dark Pendulum Magician Girl, and be Pendulum Fusion monsters like how Odd-Eyes Rebellion Dragon is a Pendulum Xyz monster. Naturally, their pendulum effects would either assist with magic and trap cards or getting Fusions out on the field.

If Arc-V's really is a crossover, Jonouchi will make an appearance sometime soon.
Notably, with the Clash of Rebellion boxset for the TCG/OCG, the Red-Eyes archtype got a major boost with a lot of new Monster Cards, Spell, Trap, Fusions, and even an Xyz monster based on supporting Red-Eyes. Considering Red-Eyes was you know who's signature monster...

Leo is just a pawn
Leo Akaba is focused on finding the Yuzus/bracelet squad, but the question comes where did he get the information that they're important? I think someone is using Leo as a pawn to draw out the darknesses in the Yuyas. By taking the Yuzu's away, the Yuyas are fighting and absorbing each other. What if the plan is to force all four of them into one being and then release the darkness inside of the Yuyas for a plan.

Serena will start to fall for Yuya as a result of spending time with him
It's obvious to the audience that Yuzu has a crush on Yuya and maybe even vice versa for Yuya. Nearly every dimensional counterpart feels the same towards their partner (Yugo/Rin and Yuto/Ruri). However I doubt Serena will ever feel anything towards Yuri, given how disgusted she was with Academia's actions; it doesn't help that every student who's there is psychotic. Yuri has even attacked all of Serena's dimensional counterparts without batting an eye. Now that she's part of the good guys, this would make for some interesting turnout, especially when she meets with Yuzu again and they start fighting over Yuya.
  • Some support in this theory: Serena and Yuri are the only dimensional counterparts that don't have any kind of Ship Tease, possibly they don't even know each other.

There will be some misunderstanding that will cause Yuya to fight with Yugo
Perhaps there will be several reasons why Yuya will engage Yugo in a duel, as hinted in the third opening:
  • Yuya is influenced by Yuto to attack Yugo.
  • Yugo, being the hothead he is, will attack Yuya, forcing Yuya to defend himself.
  • Berserk Mode once again takes effect between the two.
  • Yugo wants to "test" Yuya's strength and if he wins, he will hand over his signature dragon, thus giving Yuya access to Synchro monsters, similar to how Yuto's defeat give Yuya access to Xyz monsters.

Dennis will eventually betray the Lancers and be replaced or be won over to the good side
We all know Dennis is planning something devious and/or will be reporting his spy work back to the bad guys. When he's inevitably outed, the Lancers will need a new member:
  • Masumi can join since she's a pretty strong duelist and specializes in Fusion.
  • Kachidoki Isao may join and undergo some Character Development that may make him see that dueling doesn't always have to be about winning.

Or Dennis may grow to like the Lancers and have doubts about his mission, eventually pulling a double cross on the Fusion Dimension.

The Performapals are a Fusion archetype
That's why two of them focus on Fusion (Trump Witch and Mammoth Splash), and why Rank/Level-modifying is covered by two Magicians. (Well, that and the fact that the Magicians would be cooler.) There would be Extra Deck Performapal Fusions in the future.

Yoko Sakaki (Yuya's mom) is from the Synchro Dimension
The preview for Episode 52 has her appear with a Duel Disk, on a motorcycle, with an aggressive expression, and shouting. All of these together suggest she's a Synchro Dimension immigrant.

Yuya will eventually absorb Yugo...
... Possibly prompting Jack and Crow's attack on Maiami City. And Yuya will become even more unstable, with his Berserker mode becoming even scarier and more powerful.
  • There's a Level three Magician Tuner (Noble Dragon Magician) that works specifically by lowering Odd-Eyes monsters' Levels to four, and can only be used to Synchro summon for a Dragon-type. Thus guarantees that Yuya will get a Level seven Dragon-type Synchro.

Fusing the dimensions actually involves fusing the Yus.
Berserker Yuya might actually be a double-edged sword for Reiji. Leo Akaba (or maybe the possible Bigger Bad mentioned in the "Leo is just a pawn" theory above) actually wants to let the Yus fuse (and perhaps the Yuzu counterparts, too), or at least, if he didn't account for the existence of Yuri also having counterparts, it will seem beneficial for his plan. He might even want to create the perfect soldier (or weapon); the fact that he has the extremely competent and obedient Yuri on his side helps.

However, there might be a catch to this, too; after pushing and/or manipulating Yuri into fusing with Yuya, Berserker Yuya will be too powerful and/or unstable to control, biting Leo Akaba in his interdimensional-travelling ass. Alternatively, the Yus will defuse or regain control at the very last moment, either because of The Power of Friendship (especially if all the Yuzu counterparts are present) or because of Yuri turning against Leo (maybe being a case of The Dog Bites Back and even a Heel-Face Turn). Possibly both.

Yusho Sakaki, Yuya's father, will be revealed as the true Big Bad of ARC-V.
He may also be reason Yuya has his berserker mode in the first place. He helped create action duels in standard to create a way to use Duel Monsters as a weapon, and likely provoked the Fusion Dimension into attacking the Xyz dimension to start the war. The reason for this may have something to do with Pendulum Summoning, or an attempt to gain control over all the summoning types.

Kurosaki's injuries are going to cost him in the future.
It seems like Reiji is going to take the Lancers out of the dimension soon, but the last Xyz duelist broke his ribs and hasn't had a trip to the hospital or a moment to rest. Most likely, when Yuya and the Lancers fight whatever Five-Bad Band Academia has, his ribs are going to act up at a crucial moment, either making him lose and be carded or should he win, he will be forced to leave the battlefield.

Yuya will gain some kind of "king" title.
Following the same naming sense as the past series with Yugi's King of Games, Judai's Supreme King, Yuma's emperor's key. The way he addresses his Pendulum magicians the first time he summons them (the whole "O Magician of Creation, who watches over harmony") seems like a king addressing magicians under his service at court. He never says those lines again afterwards. Then there's that "Come forth, my monster servants" line that keeps popping up. Maybe since Yuya doesn't remember what he used to be (or whatever that darkness is), the magicians themselves are coming to his aid when he most needs them out of loyalty.

Arc-V and the alternate dimensions are not in the same continuity as the main Yu-Gi-Oh! GX timeline.
Since BBT is confirmed canon for 5Ds, that means it, the first / second series anime, and GX are in the same canon timeline. Since this messes with the possibility of Yugi and co. appearing in the series since Jack and Crow are going to be making an appearance, Arc-V and the alternate dimensions will be revealed to be in it's completely own continuity, with the alternate dimensions being based on the different anime series, with events playing out similarly, but not exactly (for example, BBT is obviously not canon), to how they happened in their respective series, that way more characters from past series other than just Jack and Crow will be able to appear.

Yuya's pendulum is an actual Soul Jar
Along the lines of Madoka Magica's soul gems, if Yuya's separated from his pendulum by a certain distance he will be knocked out cold. If anything happens to the pendulum, it gets chipped or whatever, he'll suffer real damage. As the series goes on and he keeps getting pushed past his breaking point, his pendulum will get murkier and murkier.

Yuri is even more of a Stepford Smiler than Yuya.
There are three main parts to Yuya's personality: His fun-loving and goofy attitude (in Duels, at least), his conviction to his friends, and the crapton of trauma he tries to hide. Looking at Yuto and Yugo, I noticed that they each have one of these as a dominant trait: Yuto's conviction to his friends is his prime motivation for fighting Academia (he's certainly not goofy and doesn't hide his trauma), and Yugo appears to be goofy and a bit spacey 24/7 (apart from Rin, he hasn't talked about any other friends, and he has no indications of being traumatized at all).

This left Yuri with the hidden trauma, and if you think about it, it kinda fits. Yuri gleefully cards people with no second thoughts and thinks his mission is fun, and unless they're sick in the head (which could be the case here), there's only two ways someone can actually enjoy this: 1. They're brainwashed, or 2. they've been traumatized to such horrifying levels to the point that their current ways are the only way they can cope. Child Soldiers often go through emotional hell before becoming the cold-blooded killers they are, and since Academia is full of these people, it's not hard to imagine Yuri, a higher-up, being the most broken of them all. We know Yuri has issues regardless, but they may actually be something sympathetic. It's probably the only way he can be redeemed at this point in the show.
  • I doubt he's a Stepford Smiler; Word of God is that he willingly helps Academia out of fun. Maybe Academia brainwashed him into their service, but he genuinely likes what he does. I'm gonna put him closer to being like Yuu: he gleefully causes pain because he thinks it's all a game with no consequences, and thus ccan't grasp what he's doing as wrong.

The 4 dimensions, Yuya & Yuzu and their respective dimensional counterparts exist as they are now because of the darkness inside Yuya.
Between Yuya's conversation with Yuto & Academia's goals it has been implied that the 4 dimensions were once one in some way and that they can be (re)united regardless of if they were once one or not. The ability to manipulate memories/entire worlds in general with cardgames is nothing new to Yu-Gi-Oh! just look at Yu-Gi-Oh! ZEXAL for example, its ending could very well be the reason the current ARC-V plot exists.

Considering that Yuya's berserk mode is a result the darkness, his counterparts also have the ability and Yuya's got worse after merging with Yuto, it's likely that each of them possesses a piece of the darkness. As Reiji noted, Yuya evolves every time he is exposed to another dimension's summon method (makes sense since he is the standard Yu and likely the original one as well should the theorized dimension split have happened after he was born), his merger with Yuto giving him an XYZ pendulum monster as opposed to the pure fusion monsters he got from being exposed to Polymerization alone (fusing with Yuri will likely give him a fusion pendulum monster).

My guess is the Yu boys exist to hide the darkness, the dimensions and the Yuzus exist to keep them away from each other and someone wishes to "complete" the darkness thus creating the perfect duelist who has access to pendulum versions of the other 3 extra deck summon methods and who knows what else. Also Yusho is involved with this somehow giving Yuya the means to pioneer Pendulum summon because he is the true Big Bad who is after the darkness inside his son or as the Big Good who gave it to Yuya in hopes that he could use it to tame the darkness and/or defeat the true big bad.

A conflict will arise between the Synchro and Standard Dimensions due to a massive misunderstanding.
Right now, we have:
  • Yuzu having traveled with Yugo to the Synchro Dimension. She doesn't know he's Yugo (who she knows had some responsibility over Yuto's apparent death).
  • The Lancers, partially conformed by Yuya (who still believes Yuzu's been carded), several Child Soldiers (with at least one Knight Templar), a Mole and Sawatari, about to travel to said dimension. While being led by resident Manipulative Bastard Reiji.

None of that can end well. On one hand, Yuzu might, at least initially, antagonize Yugo; alternatively, Yugo might not be of much help for Yuzu if she wants to warn the Synchro dimension of the war or stop another possible conflict (even if he believed her, he probably wouldn't have much credibility where he lives, would he?).

On the other hand, Reiji's actions up until now (letting several participants get carded, lying to Yuya about Yuzu... ) and Yuya's belief that Yuzu has been captured by Academia bring lots of potential for conflict (Yuya inevitably finding out at some point that Yuzu was safe all along being one possibility). The inevitable appearance of Yuya's Berserker Mode in the Synchro Dimension might not be exactly pretty, either.

In short, there are several factors that might end up in the authorities in the Synchro Dimension (possibly Jack Atlas?) deeming all non-Synchro individuals to be intruders and even a menace, despite Yuzu (and likely Yugo)'s efforts. With Reiji likely having a share of the fault somehow.

  • Possibly confirmed and jossed. The lancers are arrested upon arriving, but Reiji manages to get them released and is currently working on manipulating his way into an alliance with the Synchro dimension. Whether or not he'll succeed is currently up in the air, but at least one high-ranking official wants them to fail.

Reiji knows Dennis is a spy
Dennis is right; Reiji indeed must have caught his transactions with Yuri on camera. Reiji's probably just feigning ignorance to feed Dennis wrong information or get info on Fusion out of him.

Yugo and Yuzu will join the Lancers
Chances are that Reiji would know that Yuzu would be pretty important to dear ol' daddy's plans, as well as being Yuya's Living Emotional Crutch as well as being a strong duelist. Yugo would likewise be initiated as a strong duelist and one of Yuya's counterparts. Naturally, when that happens, either Yuya, Yuzu and/or Yugo will duel Reiji (for related reasons, Yuya being pissed that Reiji lied, Yugo misunderstanding his motives to trying to recruit Yuzu and Yuzu likewise having similar misunderstandings about Reiji's, the former two also wanting to protect the latter. Reiji's own reasons will be to gauge their strength).
  • Of course, there is also the possibility of Yuzu's bracelet spiriting at most herself and either Yuya or Yugo before the duel happens...

The evolved advanced summoning methods (Super Polymerization, Accel Synchro, Rank Up):
With Arc V practically being "Callback: The Series" for Yugioh, there's some pretty strong hints that the evolved versions of the advanced summoning methods are set to reappear too. 'Rank Up' has already been debuted by Kurosaki and the ability to ride your monsters seems like the perfect setup for 'Accel Synchro' since one can build up the necessary speed even in a ground duel. And as for fusion, now that it's been revealed that Academia's goal is to fuse the alternate dimensions, it's not impossible that the card canonically established in GX as having that ability, 'Ultimate Fusion God' is finally set to appear in full, and that they're sacrificing people to create a 'Super Polymerisation' to summon it.
  • Sora has already shown one advanced fusion method (fusion with other fusion monsters). Also I would not be surprised if a contact fusion user eventually shows up. Also with Jack retuning we will likely get Double Tuning as well.

Each alternative Dimension is a What if the main Protagonist of their respective series didn't exist
So far we have seen each alternative dimension and they all suck for differing reasons. If Judai/Jaden didn't exist and relax Duel Academia, it would create a much easier manipulable school, explaining how Leo was able to take control. The Synchro Dimension is even more classist than 5D's was, probably the result of Yusei who was able to fix classism, didn't exist. The Xyz Dimension is a pile of ash because Yuma didn't exist and protect Heartland.

The reason for the dimensional split is...
Because of a horrible Apocalypse How scenario, specifically, Class Z. To elaborate: At first, the first four YGO series all shared the same timeline, and a few years after the end of ZEXAL, all of the Extra Deck summoning methods began to see an equal amount of support, like how Konami is trying to do now.

However, the incredible power of the evolutions of these summoning methods (Contact Fusion, Accel Synchro, Rank-Up) caused an anomaly much like Darkness or Zero Reverse to develop, but on a much, MUCH more destructive scale. This anomaly eventually took the power of Chaos left out of control after Don Thousand died as a vessel, and eventually began to wreak havoc on the YGO universe, destroying the Duel Monsters Spirit World, the unseen dimensions mentioned by Yubel, the Underworld where the Earthbound Immortals came from, and the Astral/Barian World, leaving only Earth.

The various protagonists of every previous series, now likely much older (Or only slightly in the case of the ZEXAL cast since the event would be closest to their timeline), tried to stop it, but almost every duelist available ended up defeated, until a way to at least stall the anomaly was discovered. The end result was the four dimensions based on the summoning methods being created, with Yuya and his dimensional counterparts representing the sealed Destruction part of the anomaly, with Yuzu and her dimensional counterparts representing the sealed Creation part of the anomaly. The only characters who did not die in the battle were Jack and Crow, who ultimately were reincarnated in the Synchro dimension (Since they mainly used Synchro Summoing), but did not have any memories of the battle.

Akaba Reo is thus a Well-Intentioned Extremist who wants to see the previous world restored, perhaps knowing that he's perhaps risking the permanent destruction of the remaining dimensions, but it would, in the end, worth the risk.

Alternatively, the main protagonist of each dimension has been captured by some evil force in their home worlds
People have talked about each dimension being a world where the protagonists didn't exist, but then what about the trials they faced? Who defeated the Light of Ruin, or took down the Earthbound Gods, or stopped Don Thousand?

I think it'd be more interesting if bad guys in each dimension noticed each protagonist, realized he'd get in the way of his/her own notorious plans, and decided to take him out before setting their plans into motion. People have talked about the classism in Neo-Domino, but have we actually seen a Satellite? It's possible that Yusei's work was undone by some higher force. In that case, Jack's upset because his best friend died/went missing not long ago and now he's watching everything Yusei worked for fall apart.

Plus, this would give the new generation a chance to shine by pulling off a rescue mission for each and every previous protagonist! Or have each previous protagonist rescue themselves when given the opportunity. Either way, we get to see the old protagonists interact with each other and the new protagonist!

The Synchro arc begins a Two Lines, No Waiting arc
On the one side, we have the Lancers, who are the protagonist group. Led by Reiji and Yuya they try to combat Academia. The plots would deal with Yuya looking for both Yuzu and some answers on why there are AU versions of them both, but will be derailed by the dimension's resident Big Bad.

The Deuteragonist is Yuzu, who will be warped to various dimensions and come across different revelations about Academia's plans (and the whereabouts of Ruri and Rin) with the help of someone who will not interact with the Lancers, and will likewise wind up encountering Academia and being warped to the next dimension.

The two plots shall serve to create a Star-Crossed Lovers vibe between Yuya and Yuzu as well as set up other conflicts. The separation will also be explored by Leo to aid his plans.
Reiji and the Lancers will side with Security
Since their primary reason for going to the Synchro Dimension was to find allies in the first place, Reiji tries to align with Chess Man. The Lancers for the most part will be left in the dark concerning the state the Commons are in, resulting in a conflict of interest for Yuya when he sees that Yuzu is supporting the Commons.

At some point, Yuya will summon his ace Fusion, Xyz, Synchro, and Pendulum monster in a single turn during a duel late in the series.
Possibly against Reiji. Considering Reiji did that in his first duel against Yuya, it'd be a good way to show how far Yuya has come since the start of the series.

At some point, we'll get a fusion that requires an Xyz monster and a Synchro monster as it's fusion material.
It'll likely be used by Yuya, considering the Fusion dimension hates other summoning methods, but given the series theme so far of using all the summoning types together...

The Four Dimension Dragons are actually the true selves of the Yu boys.
We like to think of the Yu boys and their respective dragons as separate beings, but what if they're just two parts of the same whole? What if the Yu boys are the dragons in human form and every time they play their dragon cards they're actually sending out their souls and/or true/subconscious selves? If this is the case, then the dragon cards are probably Soul Jars (or, at least something similar) and it would most likely be a very bad thing for a Yu boy if their respective card was damaged. It also means that the Yu boys have been subconsciously helping themselves out, as Clear Wing has been helping Yugo and Odd Eyes has helped Yuya before.

Related to the above WMG. The bracelets are also Soul Jars for Yuzu and her counterparts
And the bracelets create artificial human constructs as an avatar for their respective dimension, Which why they pop up even when their wearer was in infancy. The bracelets themselves likewise use the power of the respective dragon and is keyed to that dragon, explain why Yuzu's didn't warp Yuya away, but did warp away his counterparts.

In the beginning, there was only 1 Dimension
But a past version on Yuya and Yuzu have been entwined in events resulting in the one dimension splitting up into four, the events of which were the result of a complex ritual that put them in a fractured cycle of reincarnation, one that may have involved an original dragon that likewise split into 4. A side effect of this is that the 8 became pieces of a puzzle that once compelted, will merge the four back into one.
  • The ritual was done int he first place because the two precursors to Yuya and Yuzu were combating a ancient evil (because lets face you can't have a Yu-Gi-Oh! series without some ancient force as the Big Bad once) and the ritual was to seal it into one or both of them. The Berserk Mode ability is a side effect of containing a significant part of the evil force and it grows proportionally stronger with the darkness (which in turn grows stronger when Yuya absorbs or is near his doppelgangers)

How/why Yuri will do a Heel-Face Turn.
Since it'd be very surprising if Yuri doesn't one day turn good, let's start guessing on how it'll play out. Feel free to add to this.
  • His Morality Pet /Living Emotional Crutch gets carded by Leo Akaba. Going by how seemingly unhinged Yuri is, if there is someone he truly cares about he'll probably be very protective and/or emotionally dependent on them. So if Leo Akaba were to card them, chances are Yuri won't let it slide. If Leo Akaba didn't know Yuri was watching him card his friend/brother (remember, we don't yet know whether or not Yuri has a sibling like Ruri does,) Yuri, knowing he isn't strong enough to face Leo Akaba alone, could seek out Yuya's help. Most likely, Yuri, while pretending to be his same sadistic self, will challenge Yuya to a duel to see if he's strong enough to save his friend/brother. When Yuya wins, he'll drop the act and say that while Yuya is indeed strong, he's not yet strong enough to defeat Leo Akaba. In order to make him strong enough, Yuri will suggest that Yuya absorbs him, but only if he promises to save his friend/brother. Yuya will, of course, agree and absorb Yuri. Then all four Yu boys (assuming Yugo is absorbed by Yuya by this time,) in one body will head off to face Leo Akaba. If Leo Akaba cards Yuri's friend/brother in front of him, Yuri will probably go crazy and try to take on Leo Akaba by himself. This, obviously, won't work and Leo Akaba will have him brainwashed to make him forget all about his friend/brother. Yuya and Yuri will duel, but the duel will start making Yuri's brainwashed memories come back (similar to what Yu-GI-Oh Zexal did.) By the end of the duel, Yuri will remember everything and the same things as the first scenario play out. As for who the Morality Pet /Living Emotional Crutch is, the most likely candidates are Sora and Dennis.
  • Its seems odd that Yuri and Serena are the only Yuya/Yuzu couple that aren't close. In fact it seems like they don't even know each other. Since memory erasing tech is available, mostly likely he separated Serena and Yuri as children and erased their memories of each other. Yuri eventually remembers this and swears revenge on Leo for this.
  • In regards to the above guess I think Yuri's path to redemption will be dependent on what his backstory is. Keeping in mind how the four boys all have a hidden darkside I like to see Yuri as how Yuya would have turned out if he didn't have a "Yuzu" (and other friends/family) to keep him grounded (and of course having Leo as a boss/possible father figure). Unlike Serena and Sora he doesn't even seem to care about his own comrades or Academia's goals making him unique compared to them. There has already been a ton brainwashing theories but if that isn't the case, with him working for Leo who is dead set on collecting the Yuzus it's possible he may actually be suffering from some major Tomato in the Mirror issues depending on how much he actually knows about himself. Thus dueling and being absorbed by Yuya may eventually allow him to find peace with himself.
  • He might also realize that Leo's plans could be Omnicidal Maniac levels of destruction and pull a Redemption Equals Death or Evil Versus Oblivion Enemy Mine with Yuya

Crow took the bullet for Jack sort of speak in the past, hence his marks and his lack of social advancement
Yugo suggested that going to the facility makes one ineligible to advance, and given that the other Satisfaction Member in the picture, Crow, has marks and is still in the Commons, it is quite possible.

In addition to Yuya, Yuzu will also gain Synchro and Tuner monsters while in the Synchro Dimension.
Not much else to say, really. Yuzu and Yugo will be on the run from security for a greater part of the Synchro Dimension arc from what the setup episodes were suggesting. As a result, Yugo will likely teach her Synchro Summoning as a way to better defend herself while in the dimension.

Jean-Michel Roger has no clue about the inter-dimensional war
Because he's been pretty smug thus far, looks like the kind of guy who's used to total power, control, and knowledge, and having him be knocked off his high horse by an Outside-Context Villain would likely be hilarious to watch. Even if he doesn't team up with Reiji and the Lancers, it'd still be funny.

As an Contrast, Roger would instead of helping the Lancers, he would conflate them with the invaders.
He barely has a clue to their existence and would also likely to take threats to the status quo (which would include Yugo and possibly the Lancers should Reiji learn of the Commons) very seriously.

In a contrast to 5D's Jack will help Security
In 5D's Jack has been initialy shown as an ally to Goodwin, likewise it would stand to reason that Security would've hlped Jack repel Yusei (and in fact has done so). This tine, Jack and and Roger are sown to be somewhat close acquaintances and Roger would eventually have Jack Atlas himself try to repel Yugo and the Lancers from the Tops once he realizes that Security's Mooks are getting curb-stomped left and right.

A villain will use the Entity/Lovecraft cards
The entity series consists of various Synchro, Fusion, and Xyz Monsters interacting with each other, and the ace monster, Azzathoth, reaches full power when one of each monster type is used as its Xyz Materials. Thus it will fit perfectly into Arc-V's themes for someone to use the archetype, and given they're based on Lovecraftian mythos, it makes sense if it's a villain. Perhaps The Man Behind the Man is an Eldritch Abomination as the franchise is wont to do, and it'll use the archetype.

Yuya will unlock a fifth summoning type
Inevitably, there will be a way to fuse all four Dimension Dragons, because that's series tradition. However, while all the conventional methods would work for them, it doesn't make thematic sense — why fuse/synchro/xyz summon using them if the whole point of the series is that these are alternate worlds and Standard is the base world? Why show favortism to one dimension over the other two for such a significant monster? The answer — Yuya will unlock a fifth summoning method to combine all four of them in a new way never seen in any dimension, symbolizing a combination of all four of them without using the method of a specific dimension to achieve that combination.

Or, much more simply, Yuya will create an Odd-Eyes variant that gains power if Advanced Summoned by releasing the other three dragons.
  • It could simply be a Nomi monster, summoned by tributing the four Dimensional Dragons.

The entire series is a shout out to LittleKuriboh
We know the abridged series is popular in Japan, we know the writers of Arc V are paying attention to what the fans like, and let's face it: Pendulum Summoning IS LK's most famous joke made legal.

More importantly, every time someone introduces pendulum summoning to people who haven't seen it, there is always SOMEONE who has to say "Summoning a bunch of monsters in one turn?" In question format, and then someone who accuses the duelist of cheating. In other words, claiming that move is against the rules. And despite a total lack of excuses given, that never stops the duelist from continuing the duel with their pendulum cards.

Any more support for or counter-arguments against this theory?
  • One possible counter-argument for this theory is the fact that the writers for the show aren't technically the ones who created the pendulum mechanic, that was the company konami because they felt like it would be a good new mechanic for the card game (of course, they might have been influenced by it)
    • So does anybody know what Konami's opinion on the abridged series is?

Shun Kurosaki and his little sister Ruri are the children of an adult Kotori from ZEXAL.
His looks give him away. Green hair and gold eyes? Check. That he's from Heartland, check. One can only wonder what happened to Yuma and Kotori and the rest of the gang after they went to help Astral. After dealing with the one trying to use Chaos again in the last series (and after Yuma-tachi went to help Astral deal with that problem), this led to Academia coming in and invading Heartland. Yuto, Kurosaki and Ruri started the Resistance while their parents were gone to fight against the invaders.

Tatsuya will end up as a protagonist
Either as a We already have the set up with Tatsuya, Futoshi and Ayu as the main characters, and Reira as the rival/anti-hero (especially with the Lancer Arc adding some potential backstory). Though likely this will all take place after a time-skip.

The reason some of the evolved summoning (Contact Fusion, Accel Synchro, Double Tuning, and Rank-up Magic) methods are unknown in standard is they showed up in the 2nd half of their respective Anime or Cardpack Series

Miracle Fusion showed up in the 1st Half of GX (the card itself shows up at the end of Sacred Beast Arc in episode 46). Where Contact Fusion (VWXYZ Fusions but see below) was first used by Jaden in episode 67.
  • For the sake of clarity Miracle Fusion is banish from graveyard and/or field. While Contact Fusion is is when a Monster is fusion without Polymerization or Equivalent (Hex Sealed Fusion or Trump Witch).
    • it should be noted that while VWXYZ Dragon Cannon is first contact fusion (under the definition I gave of no polymerization or equivalent), unlike the Gladiator Beasts or Neo Spacians (and now Ritual Beasts) they do not have return to extra deck to special there materials from deck/banish zone. Which would tie into when Sora says they do not use real fusion. Sense a real contact fusion monster would have a return to extra and special summon its materials clause.

There has been has been miracle fusion in standard, Masumi when she used Fragment Fusion against Yuzu to summon Master Diamond, by banishing the materials from her graveyard, and then Reiji in episode 40 against Barret to summon D'Arc. It should be noted that these two fusions are only from Grave (the banish effect) not from field and grave like most miracle fusions (such as for example Frightfur Fusion).

Accel Synchro and Double Tuning. Both only appeared in the WRGP (and the build up to it). Not the 1st Half/3rd of the Yugioh 5d's which dealt with the Dark Signers.

  • For sake of clarity Synchro is synchroing a with a tuner synchro and a non tuner synchro. Double Tuning using two tuners and a synchro to make a new synchro.

One of the other evolved summoning methods in 5Ds was called double synchro (or that is what my friends and I called it), where you use a non synchro tuner with a synchro to make another synchro (the Majestic Dragon Cards). This has appeared in Standard where Yaiba used X-Saber Wayne and Palamuro to synchro for X-Saber Hyunlei in episode 24.

Xyz, Rank Up Magic vs Xyz Change, Rank Up Magic was only used in the second half of Zexal (or Zexal II) when the Barians showed up, and used Rank-up Magic (which the heroes would also later acquired). On the otherhand Xyz Change was used in the 1st half of Zexal.

  • For clarity sake Rank Up Magic is using a magic card like Rank-Up Magic Astral Force or Rank-Up Magic Revolution Force to make a higher or lower rank Xyz Monster. Xyz Change is using a Rank Monsters effect or summoning Requierements (I.e Pleiades into M7, or a Hieratic Dragon King of Atum into Gaia Dragon, the Thunder Charger)

  • Xyz change can be first seen where Yuma goes Number 39: Utopia to Number C39:Utopia Ray in episode 18 of Zexal, in Standard the obvious example is Hokuto wents Pleiades into M7 in episode 9 and as Reiji mentioned/implied no one in Standard has seen Rank-up Magic Spell Cards until Kurosaki used them in episode 34.

Arc-V is a Continuity Reboot of the Yu-Gi-Oh timeline.
While there are references galore, none of them directly refer to the old plots or characters. In fact, since Crow showed up with a completely different background (he seems to be raising these kids himself, with no sign of Martha), at the very least 5D's cannot be canon to it. No, Arc-V is the Ultimate Universe of Yu-Gi-Oh. If you want to do it DC style and attribute the reboot to an in-story event, it would probably be because of Yiliaster meddling with time and/or Don Thousand and Yuma rewriting the universe with the Numeron Code.

Jack's ace is going to be Hot Red Dragon Archfiend.
Because it looks like Red Dragon Archfiend, but may not be Red Dragon Archfiend. (Hot Red Dragon archfiend is his ace in the manga, as opposed to the anime).
  • Jossed, it's a new card , Red Dragon Archfiend Scarright / Red Daemon's Dragon Scarright

Kurosaki's line about assuming the other Lancers had ended up lost between dimensions is Foreshadowing for something.
The question is, is the Foreshadowing about someone who is already lost between dimensions, or is it that a character will at some point in a later arc end up in this situation?
  • And it would be revealed that the one lost between dimensions is Yusho, and Leo's plan to unite the dimensions is in order to find him; for what reason, I don't know, but maybe for something that happened in the past.

Dennis' Performages will be similar to Sora's Fluffals...
As of right now, they look cute and goofy, but once Dennis reveals his true nature and starts using their fusions, the end result will be akin to the Monster Clown trope.

Once Yuya gets Clear Wing Synchro Dragon, it'll end up teleporting him to different dimensions against his will similar to Yugo.
Because, lets be honest, we ALL know Yuya will get Clear Wing Synchro Dragon from Yugo at some point. That said, it'll likely start teleporting Yuya around the dimensions against his will like it's doing to it's current master, possibly to the same dimension that Yuri is currently in. The prime candidate is the fusion dimension, since it would give the Lancers a prime reason to go there despite not fully preparing for it yet. The Xyz dimension is also possible, albeit unlikely since Xyz summoning has already gotten a lot of focus as is.

If Jean-Michael Roger isn't already secretly working for Leo and Academia, he'll prove to be a Big Bad Wannabe.
  • Yeah, this seems likely. He seems suave and confident only because he has the highest authority in the land, and has the manpower to do whatever he needs to capture undesireables (who haven't shown a desire to harm anyone). If Academia decides that the lure of catching the last two renegade Yu boys, and the last two of their female counterparts, to be too great (likely, since that's what caused them to send a strike force to Standard), they may send their forces to Synchro, and suddenly the Security forces, used only to minor criminals, now have to deal with an entire army, who is not afraid to shoot to kill. That may cause Security to break ranks and run away, while Academia starts carding Tops and Commons alike. Basically, Roger is too focused on maintaining the status quo to be an effective villain in the face of someone with more drive like Leo.
  • Alternatively, the writers will chose to be more realistic and yet more complicated, and have Rodger realize that Academia is a genuine threat, but still be a pain in the butt. He'll cooperate just enough to provide a valuable ally, but his prejudice and long-term goals will occasionally interfere with goals that aren't completely aligned with the war. For example he'll have soldiers recruited from commons and treated like Cannon Fodder, fighting Academia while keeping the Commons down. This would be far more interesting, because the Lancers can't just outright declare him an enemy and get rid of him, yet he'll push conflict and continue being an antagonist for a long time (and possibly lead to some deeper political sub-plots that could be very interesting). Instead of wondering, "when can the heroes fight this guy so they can kill him?" The audience will wonder "When will the heroes catch this guy with his pants down so we can FINALLY get rid of this asshole?" Because villains get so much more hate when the characters aren't allowed to stop them than when taking them down is an active goal the heroes pursue.

The current hell the Lancers are going through in the Synchro arc is a test by Roger to see if he will help Reiji.
Like quite a few people, I myself wondered where the hell Reiji went during this arc. Then something hit me: What if he already contacted Jean-Michel Roger for help, but he wanted proof of what the Lancers could do before agreeing? Thus, Reiji leaves them behind, anticipating that they'll scatter and eventually get arrested (which they did), and later learn about the Grand Entertainment Duel Tournament. Yuya (most likely him) will win, and it's then that Reiji and Roger reveal the truth. This would inevitably lead to the Lancers giving Reiji an earful for going that far just to recruit help.

Each of the four dimensions has special duel rules they play by.
Standard has Action Duels, and Synchro has Riding Duels. Knowing Academia, they will probably use Survival Duels (winner gets some of their Life Energy drained, loser even moreso), as that showed in Yu-Gi-Oh! GX, and that kind of thing seems pretty consistent with what we have seen of Fusion Dimension. Xyz may have had AR Duels, before they were invaded.

Crow is gonna using Accel Synchro
His Assault Blackwings are apparently designed for this. Raikiri can become a Synchro Tuner while Kunai can change Raikiri's Level.

Yuya and his dimensional counterparts are somehow connected to the previous four protagonists
  • Berserk Yuya's hair and coat are reminiscent of Yami Yugi's, and his name's syllables are the first syllables of Yugi and Yami respectively. Personality-wise, his mentality that Duels should be only for fun is a mirror of Yugi, who acknowledges that he usually Duels with high stakes.
  • Yuri is one letter different from Yuki. His psychotic personality is the opposite of Jaden's cheerfulness.
  • Yugo sounds like Yusei Go with one syllable missing. He is impulsive and short-tempered, whereas Yusei was calm and clear-headed.
  • Yuto/Ute sounds like Utopia. He is cold and quiet, while Yuma was bouncy and loud.
    • He also entrusted Yuya with Dark Rebellion Xyz Dragon, using it to represent him asking him to bring smiles to people. In other words, Dark Rebellion is his "hope."

The Yus are four parts of a single person split into four to replace the original protagonists of the previous four series.
  • The Big Bad kidnapped Yugi, Jaden, Yusei, and Yuma, split the dimensions into four, whereas it had been one complete dimension before, and replaced the protagonists with the divided Yuya, Yuri, Yugo, and Yuto. Heavy timeline screwing or memory altering was involved. The Big Bad, whoever it is, is attempting to use the powers of the four original protagonists to take over the world. Similarly, Yuzu and the other girls are Artificial Human Barrier Maidens who were created as supporters of the Yus, and serve to keep the four dimensions separate. The reason why Leo is trying to collect them is to combine all the Yus into one Yuya and one Yuzu, reassembling the dimensions, and rescuing the previous protagonists.

Reiji is the Big Bad, or, at the very least, a villain.
  • Let's see, he's grey haired, rich, powerful, and leads an organization of professional duelists, he initially starts out as an antagonist to the main character before revealing his motivations, and holds a special tournament for the sole purpose of gathering together powerful duelists into a single team to defeat an incoming evil organization led by a member of his family. Where have we heard this before...
None of The Eight have biological parents.
While information is scarce, what we know about The Eight (Yuya, Yuzu, and their counterparts,) so far seems to imply this. First, let's look at Yuzu and her counterparts:

  • Rin: outright said to be an orphan
  • Serena: implied to have lived her whole life at Academia, so it's very doubtful that she's ever had parents in her life.
  • Ruri: not said.
  • Yuzu: implied to be adopted.

Now, let's look at Yuya and his counterparts:

  • Yugo: like Rin, outright said to be an orphan.
  • Yuri: not said yet, but, since he's from Academia, he's most likely the same as Serena.
  • Yuto: not said.
  • Yuya: the odd one out, as he has two parents who are heavily implied to be blood related to him (or so he thinks, anyway.)

It seems fairly odd that two out of the four Yuzus are confirmed to pretty much confirmed to have no parents, with Yuzu herself being implied to be adopted. The Yu Boys are harder to pin down due to one of them actually having parents (Yuya,) another one never talking about such things (Yuto,) and lack of information about the other (Yuri.) Still, with the exception of Yuya, they seem to be following the same trend. Now, if this theory is correct, it would mean that The Eight are not born the same way normal people are. Perhaps they were created by something, or they just poofed into existence one day. It also means that Yuya is adopted, regardless of what has been implied so far. Yuya will probably take this very hard, and it will most likely be revealed near the end of the series. That said, Kurosaki is a thorn in this theory's side, being the brother of Ruri. However, Ruri having a brother could be explained by Kurosaki being born in the same way as her, or, despite considering one another as siblings, by them not actually being blood related.
  • The current theory is that Ruri has orange/blond hair, so it's also possible she was adopted. I'm thinking that maybe they were all born like humans, but are actually like the Kamashiro siblings of Zexal.

Jean-Micheal Roger will pull a coup in anger for the council overriding him.
Considering how pissed off he looked in Ep. 65's preview, this has a chance of happening.

Alternatively or similarly to the above theory, Roger is a spy for Academia
  • Roger seems pretty against Yuya and co from having a proper hearing and is at least distraught to hear the possibility of an alliance with Lancers. And considering Serena had some "special treatment" when confined in the detention centre (a better kept facility compared to Kurosaki's and Yuya's group), it wouldn't be surprising if Academia had spies scattered out through each dimension. If the Counsil does side with the Lancers, he may pull the theory above

for consistency, the full name of the Lancers (Lance Defense Soldiers) will get a Dub Name Change
And the name will be initialized as L.I.D.
  • Lancers Initiative Defenders? Lancers Initiative Duelists?
    • Now that I think about it, something like Lancers: Interdimensional Defense might work.
  • Similalry, the dub will likely change the name *Academia* to *Duel Academy*

Since Shinji will be dueling in a few episodes...
  • He will use a Spider Deck, since his last name is Weber.
    • If the name of the episode in which he duels is any indication, he will be using B (or Bee) Forces.

Theories about what happened three years ago
What we already know happened three years ago:
  • Academia invaded the Xyz dimension.
  • Jack Atlas won the Friendship Cup.
  • Yusho Sakaki vanished.
Seems strange that the writers keep using "three years ago" as the timing for so much. Taking this and running with it, let's assume all events listed above happened around the same time. Theories about what happened:
  • An in-universe Retcon erasing Yusei and the other yugioh protagonists
  • The Yu's and Yuzu's gained or were marked for their power.
  • Leo Akaba kicked off his invasion of the Xyz dimension using a super-weapon that induced an in-universe Retcon on the other dimensions.
  • Someone pulled off an incomplete Super Fusion that only partially fused the dimensions, Leo Akbar decided to finish the job using martial warfare and genocide.

Reiji kept the Intrusion Penalty on the Lancers Duel Disks to use as a shock collar in case one of them goes rogue.
...Or when he goes nuts and just shocks the Lancers for failing him or daring to question his actions.

Action Cards are Context Sensitive.
We have never seen the front of an action card before it is picked up. And once picked up, it's effect is always useful to the events going on. No one has picked up Mirror Barrier when they're about to be attacked directly, or Avoid when their monster is being destroyed by card effect. The front is blank until picked up, at which point it becomes whatever the holder needs it to be.

  • One flaw: why did some of them turns out to be a trap like the card Yuya picked in early episodes?
    • In that case, then the theory needs only to be modified slightly. Action cards are either Spells or Traps. When picked up, the Action Spells become whatever is most useful. The Traps, meanwhile, become whatever is most harmful.

The losers of the Friendship Cup will get captured by Academia or carded.
  • Jossed. They are forced to do harsh labor in the underground trash plant.

Yuya's pendant will turn the Tuning Magician card he received in Episode 65 into a Pendulum Card.

Jack Atlas is a pawn of someone or more higher above.
When you think about it, would someone really turn his back to his friend once he became a king? Added that Jack seems to never visited his friends in the past three years and it is even weirder. My guess is Jack is a pawn for someone or more above and the King Position is just a front for nefarious plan(s).

It's possible Sam misinterpreted the meaning of Jack giving him Tuning Magician
It's effect could be a really good one and Sam probably wouldn't understand cause as a Common resident he couldn't read very well.
  • Maybe it's Difficult but Awesome. A card whose effect is unintuitive, but if you use it just so, it's actually pretty good. Jack saw some potential in Sam, and gave him the card as a test. Jack know's it's good, and Yuya will be able to use it correctly, but Sam didn't understand.
    • Just the name should be enough to tell that Sam misunderstood Jack's gift big time. It's a tuner. What are tuners? Small monsters that by themselves are useless, but can create big, powerful monsters by tuning with other monsters. The whole theme in 5Ds is that Synchro Summoning is a metaphor for the weak becoming strong and evolving through determination and cooperation. I personally suspect that it's a setup for the moment when Yuya will be able to "rediscover" the true meaning of Synchro Summoning and remind the whole City what it stands for.

Guesses for Fortune Cup match-ups
  • Yuzu vs. Serena. Or Serena vs. the shadowy figure (if it is really Barrett)
  • Tokumatsu vs. Sawatari.
  • Yuya vs. Yugo (which will be interrupted)
  • Dennis vs Kurosaki.
  • Yuya vs. Kurosaki. (with Yuto possibly playing a role)
    • Jossed: Tokumatsu vs Yuzu. Serena vs Tony, Yuya vs Duel Chaser 227, Sawatari vs Yugo.

Yuya is going to have an obvious personality change after absorbing Yugo.
If this chart is right, Yuya has to defeat Yugo in order to advance. After seeing that his Entertainment style does not work with the people of the City and knowing that everyone he knows would be forced to go to harsh labor, he would be very upset. Once he defeats Yugo and experiences the disappearance of another counterpart, he notes that the audience cheered for his victory despite possibly killing another person. This leads to Yuya having an emotional shutdown for a good number of the episodes.
  • Anything on that chart other than the first round pairings is hypothetical.
    • That being said, Yuya and Yugo dueling and fusing at some point seems like a Foregone Conclusion, depending on how far the Cup goes without things going to hell.
      • Actually, there is also speculation that Yuuri will be the one fusing with Yuugo during the invasion. Though it is likely they will all be in one body at some point or will separated back to their own beings.

In Sawatari's duel with Yugo, he will lose, but be the first person to defeat Clear Wing in battle.

Melissa Claire is actually Yugo's mom.
Not originally my idea but I have to share it. Yugo's mom could possibly be Melissa Claire, the MC of the Synchro dimension. I was told she seems to have a similar "face" to Yuya's mom and i can kinda see that, not to mention her unusual tolerance and care for the commons unlike most "Top" characters....if she really is one. Plus of course her weird "I must keep my eye on him" phase that she said to Yugo. To top it off, I just realized Melissa's last name Claire is obviously french for Clear...like Yugo's Clear Wing Synchro Dragon! Ding! Ding! Ding! We could have a winner here! But only time will tell. Of course if it is true, Melissa needs some parenting advice....unless maybe she was forced to give up Yugo???
  • Alternatively, she'll end up adopting Yugo by the end of the series.

Something weird will happen when Yuzu and Serena duel
Given how incredibly unlikely it seems that Serena will lose to her opponent due to his minor status, the two girls seem to be set up as opponents in round 2. And given that the Yuyas can't duel without something creepy or off happening, I suspect something different but equally unnerving will happen with them.
  • Conversely, it might be a good thing. While the boys can't get near each other without flying into a blind rage where they risk absorbing one another, them dueling may have a productive effect. If Yuri and Serena had their memories wiped to keep them apart (and Yuri was further made Brainwashed and Crazy), it might make her remember Yuri (possibly as he was was), or it may counteract the efrcts of the boys dueling, such as separating Yuto from Yuya.

There IS a Ritual dimension, but it's existence is going to be a surprise
  • Why? Well, we had Mieru focus on Ritual summoning to show it's still around but is also said to have trained in it just as characters from standard need to train in Synchro, Xyz, and Fusion summons. As the odd summon out, fans would think because it didn't use the Extra Deck it didn't have a dimension. Plus, the series is Yu-Gi-Oh! ARC-V, V perhaps as in 5, as in about metaphorical or supernatural connections or "arcs" between five different dimensions.
    • I wonder if the existence of the Odd-Eyes Gravity Dragon has something to do with this.
    • As the odd one out, maybe it will not follow the same formula like the other other dimensions like it won't have its own version of Yuya and Yuzu.

Yuya will use the other evolutions of Odd-Eyes.
Unfortunately, it would only happen after he absorbs all of his counterparts and let the darkness inside him take over or was overpowered by the said darkness.
  • The preview for episode 71 shows that Odd-Eyes Saber Dragon will appear.

We will finally learn Duel Chaser 227's name in Episode 71

Shinji is Kurosaki's Synchro Dimension Counterpart
They have similar hair, use similar swarm tactics, and speak of revolution. Both Raid Raptors and Bee Force also have the similar attack manipulation as well. I don't see why other characters can't have an alternate universe counterpart, especially when Kurosaki's sister is one herself.
  • It's strongly implied that only Yuya and Yuzu have inter dimensional counterparts because of some unknown magical power they have, Ruri being one of Yuzu's counterparts. Also, Yuya, Sawatari, Serena or probably would have mentioned it when they met Shinji, or at the very least Kurosaki or Shinji would have taken notice of it when they met, even if they didn't have time to talk about it.

Sam is another Mole for Academia
He stole the card from Jack and gave it to Yuya specifically so that Jack would assume Yuya stole it, dividing the Standard and Synchro dimensions to make a military alliance even more unlikely. Also, this would mean Jean didn't give the fusion card to 227, Sam just gave him a forged letter to ensure he'd use the card. Why would Jean even care about letting a failed security member redeem himself? The only lancer he's taken an interest in is Serena, so he has no reason to want Yuya taken out in the first round.
  • There was a flashback that shows Jack giving Sam the Tuning Magician card but Jack can still assume Yuya stole it from Sam.
  • However, unlike Roger, Sam may not have access to the pairings for the friendship cup, so it would be hard to forge a letter telling 227 he will face Yuya if he doesn't know it'll happen.
Rin will be revealed to be a Violently Protective Girlfriend towards Yugo.
It's been said that she acts sort of like a mother to Yugo, so it's possible that she's developed some protective tendencies towards him.
