* {{Adorkable}}:
** Astral. Every one of his attempts to understand human culture or emotions ends up this way. (The big eyes don't hurt.) Special mention goes to his first time experiencing food while he's merged with Yuma.
** Alito imagining all the ways he could win Kotori's heart and him grinning as he and Yuma messed with each other after their first duel qualifies him.
* AlternativeCharacterInterpretation: When Nash uses [=CXyz=] Barian Hope against Yuma, he pays 400 LP to activate its effect instead of using its Overlay Units because he says the units represent his fallen Barians. However, he even refuses to detach Vector's unit, even going so far as to imagine Vector dueling with him when he activates its effect, even though he made it clear just a few episodes ago that Vector "had no soul" (or "was on his thirtiest chance" in the dub). [[EasilyForgiven What changed Nash's mind?]] Is Yuma's AllLovingHero personality rubbing off on him? [[ItsThePrincipleOfTheThing Is he just acting on principle?]] Or did Vector's HeroicSacrifice convince Nash that Vector really had changed for the better?
* AmericansHateTingle:
** The series itself, though mostly in the west, specifically with the character designs and the younger protagonists. While it is often not looked at as being "epic" when compared to 5D's, it actually has better ratings in Japan than 5D's did. Coming out in the middle of the downfall of 4Kids and (possibly consequently) having what is widely considered the worst English dub in the franchise probably didn't help its popularity too much.
** Yuma too is not as popular as the other main characters, at least in the anime. Reasons include his lack of dueling skill at the start, really stubborn attitude, his status as an IdiotHero, [[{{Hypocrite}} hypocrisy]], [[TheMagicPokerEquation Shining]] [[AssPull Draws]], and his dub voice. At least his CharacterDevelopment and BreakTheCutie moments were able to [[RescuedFromTheScrappyHeap mitigate this]] to an extent.
* AngstWhatAngst: Despite all that has happened to Yuma, especially with [[spoiler:Vector]], he has yet to actually deal with [[spoiler:the betrayal]]. Shark even points out that he shouldn't be so trusting considering what happened but Yuma just says that he can't change his trusting nature. In the end, Yuma never does change his ways and that is what [[spoiler:ultimately affords Vector a ''very'' small bit of redemption before death]].
* AntiClimaxBoss: For all that [[spoiler:V]] was hyped, he didn't turn out all that impressive in his duel with [[spoiler:Kaito]]. While part of the problem is how he spent the entire thing acting as MrExposition, his strategy boiled down to tanking behind Dyson Sphere's ability to negate all attacks hurled at it, then direct attacking with its effect to bypass [[spoiler:Kaito's Galaxy-Eyes Photon Dragon]]. Effective, yes, but not on the level of nail-biting what will happen next sort of suspense that his brothers' duels had. [[spoiler:Kaito]] [[TheMagicPokerEquation just so]] happened to have a perfect combo to summon [[spoiler:Neo Galaxy-Eyes]] and win, and [[spoiler:V]] had no counter for it despite having seen the same card defeat [[spoiler:both of his brothers in their Tag Duel against Yuma and Kaito]].
* AssPull:
** As per ''Yu-Gi-Oh!'' tradition, being the main protagonist means Yuma is entitled to as many of these as the plot demands. It's a specifically mentioned power when he's in [[FusionDance ZEXAL form]], Shining Draw, which allows him to create completely new cards out of thin air. [[spoiler:ZEXAL II takes it a step further and allows Yuma to completely change a card ''in his hand'']], though this was done only once.
** Eliphas demonstrated [[StoryBreakerPower the ability to perform Shining Draws]] ''[[StoryBreakerPower at will]]''. However, this makes a degree of sense as he is the embodiment of and protection measure for Astral World.
** Don Thousand's victory over Mizael. Having a card that can change any spell the latter plays is hokey enough, and being able to use it directly from the deck even more so. What truly makes it a shining example is that the card Don Thousand pulls from Mizael's deck, one that causes him to [[http://yugioh.wikia.com/wiki/Card_of_the_Dragon_King sacrifice all his monsters and take damage equal to their combined attack points to draw cards for each monster]], is so counter-productive that it's a wonder why he even has it in his deck (and naturally, the card was never seen before or since).
** The manga suddenly changes the gameboard around several times. [[spoiler:First off, Doctor Faker and Mr. Heartland's motives go from [[WellIntentionedExtremist wanting to destroy the Astral World to saving the human world]] to [[OmnicidalManiac just destroying both worlds]] in a single chapter, with no explanation given at the time. Then Shark's hitherto-unmentioned [[ChildhoodFriends Childhood Friend]]/RivalTurnedEvil Yagumo takes over as the main antagonist. Then it turns out that Dr. Faker was DeadAllAlong and that Mr. Heartland was just controlling his image to manipulate Haruto and Kaito (it's at this point that it's revealed why destroying both worlds makes no sense - it's not actually happening). Then Yagumo kills Mr. Heartland in an [[StoryBreakerPower utterly ridiculous way]]]]. Later, there's the [[spoiler:emergence of E'Rah in the final duel that comes almost completely out of nowhere]].
** The dub unfortunately creates several of these in ''Zexal II'' when it comes to summoning certain cards since they omitted their method of summoning. Of course, if someone knows the cards' characteristics, they would know but those who don't are left wondering how the characters were able to summon those monsters. And even in the former case there are problems because it might happen that they cut certain scenes making the scene even more confusing. [[note]] Example: at one point, V special summons Deep Space Cruiser Nine by sending a Machine-type monster from his hand to the Graveyard and he explains it but the dub not only omitted V's explanation but also cut the scene where his monster is sent to the GY.[[/note]]
* BizarroEpisode:
** Episode 81 is probably the closest thing to this. It starts with Kotori and Cathy arguing about who's going to be the cheerleader for the Numbers Club and it suddenly snowballs into all members (plus Rio) arguing with each other. So Girag concocts a plan to defeat Yuma by helping him set up the 'Friendship Games' to make his friends make up and tells him to lose purposely. After all the games, Girag brainwashes Kotori and Cathy. During the finals, Girag is forced to partner with Yuma against the two girls much to his fear as he would be forced to return to the Barian World since Yuma would lose on purpose. After a bit of back and forth, Kotori uses Rank-Up-Magic Barian's Force forcing Yuma to take the duel seriously and win. It all makes so little sense that the episode might not exist at all with the only mention of it being when Girag reveals himself as a Barian to Yuma.[[note]]Even Utopia's final attack is hilarious. Because the Terrain was a baseball field, instead of his usual swords, Utopia uses two baseball bats.[[/note]] Notably it's also the only episode where Kotori is seen dueling.
** Episode 90 too counts as this, perhaps even more than Episode 81. Here's the plot. Orbital 7 falls in love with Lilly and due to a misunderstanding, he challenges Yuma to a duel. That's it. No Barians, no important duel, no relevant plot. More than a Bizarro Episode though, it's much more of a BreatherEpisode, which is understandable considering the [[WhamEpisode last episodes]].
* BrokenBase:
** While ''ZEXAL'' is pretty popular in Japan, the fans who receive the dub are divided over whether it's the worst series in the franchise or not.
** Now that time has passed with ''ZEXAL'' having ended, the tone and pacing of the series create a bit of this; while many enjoyed the wide-expansive lore presented in the series, particularly in ''II'', along with a decently epic adventure-based story, others do not like the uneven pacing of said plot, on top of the characters being criticized for being very one-note overall.
** The duels. In general, ''ZEXAL'' has something of a reputation for weak duel writing, with earlier duels being very simplistic while later duels tend to be reliant on TheMagicPokerEquation, and many duels can be described as "character goes into their main Xyz and then uses situational Spells and Traps for the rest of the game."
** [[spoiler:IV losing to Nasch. The fact is that many agree IV very well deserved to win considering just how egregiously he dueled, busting out ''three'' Chaos Numbers despite having every single thing stacked against him, while Nasch mainly relied on Silent Honor DARK's absurdly broken and unfair effect, with the whole duel being an obvious way to establish him as the final villain]]. [[spoiler:Then there are those who believe that Nasch losing to IV would simply not work since the episodes the duel happen are obviously a way to emotionally attack the characters and the viewers, and it was already established that IV's act was more of a [[HeroicSacrifice sacrifice]] to slow Nasch down]].
** The ending of the series. Some fans argue that [[spoiler:the vast majority of the killed-off cast being brought back to life- with their [[HeelFaceTurn redemption arcs]] and (in the Emperors' case) HumanityEnsues aspects intact- via Astral's off-screen use of the Numeron Code]] is a complete cop-out that blatantly undercuts and cheapens the emotionally heavy storyline of the last couple arcs. However, other fans argue that, while perhaps somewhat cheesy in its presentation, it's a well-deserved case of EarnYourHappyEnding given [[spoiler:the '''''massive''''' TraumaCongaLine Yuma and his friends were put through over the course of the season]], on top of being an extremely open-ended SequelHook that lends itself to all kinds of FanficFuel.
* CompleteMonster: [[spoiler:[[GodOfChaos Don Thousand]] is the god of [[Characters/YuGiOhZEXALBarianWorld Barian World]] who wishes to use the [[CosmicKeystone Numeron Code]] to destroy Astral World. In the past, Don Thousand had brought trauma upon the past incarnations of the Seven Barian Emperors, including causing Alito to be executed by his best friend, to corrupting Vector into becoming a tyrant that took thousands of lives, [[FakeMemories all while twisting their memories with his Over-Hundred Numbers]] to make them believe others were responsible for their suffering. In the present day, Don Thousand releases one million Fake Number cards onto Earth, amplifying the negative emotions of the people who picked them up, and increasing the hatred and chaos on Earth enough to allow it to be merged with Barian World. Don Thousand later has two of the Barian Emperors, Girag and Alito, further brainwashed to make them fight Yuma and Astral, whom they had befriended during their time on Earth. He also has the Barian leader Nash captured in an energy sphere, with [[EnergyAbsorption his energy sapped into Vector's Life Points]] during Vector's duel with Dumon and Marin, Nash's soldier and sister, respectively. Lastly, in Don Thousand's final duel against Yuma and Nash, he forces them to make a SadisticChoice with his Numeron Network card: leave it be, and Astral World succumbs to destruction, or destroy it and the energy that would be released annihilates Earth.]]
* CrazyIsCool:
** Anna, and this extends to her Railway deck. Anna herself rides around on a flying cannon and has serious anger issues. Her deck includes such gems as a 5000 ATK monster that is easily summoned but requires a hefty cost, and a monster that destroys her own cards in order to damage her opponent.
** For a different brand of "{{crazy|CatLady}}" there's Cathy, an ElegantGothicLolita that imitates cat mannerisms to the point that she can actually ''talk to cats'', commands a horde of cats, and has [[CatNinja feline reflexes]].
* CreatorsPet: The Numbers Club in the manga are an admitted example; Miyoshi, the manga's artist, enjoys the characters, so writer Shin Yoshida gives them more screentime as a result, despite said screentime not really developing their personalities or dynamics. Shadow was another example of this. Kyoji Yagumo ended up being somewhat of an inversion on Miyoshi's part; he was getting tired of drawing him so Shin Yoshida made E'Rah the FinalBoss.
* CreepyCute: Haruto can come off as [[CreepyChild genuinely creepy]], but his design also fits squarely into a typical cute child design.
* DracoInLeatherPants: Fans seem to be fine with [[spoiler:Vector's]] sadistic manipulative personality. Some parts of the fandom redeem him by portraying him struggling with his past and claiming he's ''only'' evil thanks to [[spoiler: Don Thousand]]'s influence, and that all of the former's sadistic actions blamed entirely on the latter.
* EnsembleDarkhorse:
** [[CuteAndPsycho Haruto]], Kaito's little brother for being TheWoobie.
** [[CuteBruiser Anna]], for being a far more badass female character than Kotori, and this extends to her deck. Konami seems to be aware of this, as Anna's Railway deck continues to be supported years after ZEXAL's conclusion (including two OCG-original Numbers relating to her deck motif). All of this culminates in ''Legendary Duelists: Sisters of the Rose'' - a set dedicated to supporting archetypes used by various female characters - which had Anna as the ZEXAL representative over the likes of Kotori, Droite, and Rio.
** [[AxCrazy No. 96]], a CreepyAwesome version of Astral who completely steals the scene whenever he shows up.
** [[HotBlooded Gauche]] and Droite, two of Dr. Faker's Number Hunters, for both being likeable and badass.
** [[ActionGirl Rio]] became intensely popular just hours after her design was revealed in the anime, getting dozens of fanarts all over Website/{{Pixiv}}, and her personality was well-received too, as the first thing she did was call out Shark on his currently poor dueling performance.[[note]][[WorfHadTheFlu He was of course handicapped at the time]], and as soon as Rio was safe he proceeded to wreck his opponent.[[/note]]
** The [[BadassFamily Tron family]] (Particularly [[FriendlyEnemy III]] and [[{{Fanservice}} IV]]) are some of the series' most popular villains for the depth their story added to the series.
** [[ManipulativeBastard Vector]], full stop. He's often praised as one of the finest characters in the series even by those who don't like ZEXAL due to his sheer competence, hammy personality, and often entertaining and very dark humor.
** A 2018 popularity poll revealed that Gagaga Girl was the most popular monster in the series by a pretty wide margin (beating out the #2 by almost a thousand votes), despite being a card that was only played in a handful of duels of which maybe one was significant to any degree. [[MsFanservice Wonder why?]]
* FanNickname: Many.
** D-Gazers are called [[Anime/DragonBallZ Scouters]].
** Heartfly for Mr Heartland after [[spoiler: he assumes a fly form after he ends up in the Barian World.]]
** [[spoiler: Nashark and Merio]] for Shark and Rio after it is revealed that they [[spoiler: are actually Nasch and Merag, the 2 missing Barian Emperors.]]
** [[spoiler: Shark Knight for Nasch's Over-Hundred Number, mainly due to the incredibly obvious FunWithAcronyms involved in its name: Silent Honor's Ark Knight.]]
* FanPreferredCouple:
** The slash fans dominate the ZEXAL shipping community, due to the [[HoYay closeness of the male characters]]. The most popular couples for these fans are Yuma/Astral, Yuma/Shark, Yuma/Kaito, and Yuma/III. Speaking of Yuma/Astral, the fact their relationship is similar to the one shared by [[Anime/YuGiOh Yugi and Atem]] (arguably that series' most popular couple) definitely helps.
** Despite the fact that [[IceQueen Droite]] has feelings for Kaito, her close relationship with [[HotBlooded Gauche]], their [[OppositesAttract contrasting personalities]], and the fact that they're always in sync with one another has made Gauche/Droite the most popular pairing for both characters. It helps that these feelings didn't really pop up again after her duel with Tron, giving said fans some leeway.
** There's also a group of fans who would rather Yuma go for Cathy or Anna than the often teased Kotori, due to the latter [[UselessProtagonist contributing almost nothing to the plot]] and being [[TheScrappy extremely unpopular with the fanbase]], while the former two actually make an effort to get close to Yuma and help him and have much more interesting personalities.
* FanonDiscontinuity: With the reveal in ''Yu-Gi-Oh! ARC-V'' that there is [[spoiler:a Heartland in an Xyz Dimension, many have taken to claiming that ZEXAL isn't part of the main continuity. This theory is dampened by the fact that Fusion Monsters were used in ZEXAL and ARC-V pretty clearly states that the Dimensions are strictly divided by Summoning methods, but it's Kaito's ARC-V backstory that hammers the final nail in the coffin for said theory.]]
* FranchiseOriginalSin: Number 13: Embodiment of Crime and Number 31: Embodiment of Punishment, two Number monsters from the manga, are not nearly as disliked as the Numeron Gate monsters despite the two also sharing the same effect and having similar designs as each other. However, unlike the Numeron Gates, the Embodiments are only a duo as opposed to a quartet, they do not take the numerical place of monsters with more varied effects, and their combined effects are not as unfair as the Numeron Gates.
* GrowingTheBeard: ''Zexal'' in general is agreed to start picking up after Kaito is introduced, but two other moments are specifically highlighted:
** The Duel Carnival arc features more intense duels, introduces the Arclight siblings, who offered an intriguing sidestory that bolstered the main plot considerably, and shows Yuma’s growth as a Duelist.
** Alternatively, ZEXAL II is viewed a lot better by some, especially from episode 94 onward, though for the fans of the dueling, it ends up devolving very heavily into TheMagicPokerEquation.
* HarsherInHindsight: Kaito screaming Haruto's name is a meme, but it has become bittersweet since [[spoiler:Haruto's ''[[Anime/YuGiOhArcV ARC-V]]'' counterpart was turned into a card along with Dr. Faker's counterpart, serving as a DeathByOriginStory for Kaito's counterpart]].
* HilariousInHindsight:
** Shark being scared because his sister was returning to school was funny enough and Astral's speculation that he's so worried because of the Barians is funnier. [[spoiler:Then it turns out Rio is a Barian]].
** Shingetsu wearing a Dandylion cosplay was funny. Then you realize that this means that the person behind almost 100% of all the characters suffering...was wearing a Dandylion cosplay.
** Umimi would later become [[Creator/MieSonozaki an Xyz hating, blue-haired Fusion Duelist]] in ''Anime/YuGiOhArcV''.
** The entire tomato episode is this due to [[Anime/YuGiOhArcV Yuya's fan nickname]] being tomato. This gets even more hilarious when one of the things seen is a tomato and eggplant hybrid acting as an incredibly early spoiler to [[spoiler:Yuya and Yuto's fusion as Yuto's fan nickname is "eggplant".]]
** Kaito Fusion Summoning Twin Photon Lizard retroactively spawned a million jokes about him being either a traitor or a "Fusion scum" as he returned in ''Anime/YuGiOhArcV'' with a vehement hatred of anything related to Fusion.
** Dumon claims his name is "Nasch" as an alias, to what turns about to be the ''real'' Nasch.
** Blade Armor Ninja having a statue as one of the "legendary monsters" in the Duel Sanctuary can seem incredibly egotistical for a monster that only shows up twice in the series[[note]]keep in mind that all of the other statues were famous monsters from ''DM'' and ''GX'', but ''not'' ''5D's''[[/note]], but in the TCG/OCG it turned out to be a surprisingly good Xyz Monster for rather a while, retroactively justifying its presence.
** Ryoga shares the kanji of his name with a [[Series/KamenRiderSaber swordsman associated with the ocean]][[note]]in the latter case, his surname is spelled as "Shindai"[[/note]], on top of being an AloofBigBrother and a villain in their respective series. The similarities in name would be noticed by people such as fans as well as Shark's Japanese voice actor Toshiki Masuda, which went viral on Japanese Twitter feeds.
* HoYay: Has its [[HoYay/YuGiOhZEXAL own page]].
* IKnewIt:
** For a long time, fans have speculated that Shark and Rio were actually Nasch and Merag, the two missing Barian Emperors. [[spoiler: Then comes Episode 121 in which it was finally confirmed.]]
** The fandom's reaction to learning that [[spoiler:Yuma would duel Astral at the end of the series as the ceremonial duel]].
* ItsTheSameNowItSucks: A lot of people dislike the series for sharing quite a few qualities for the far more well-received ''Duel Monsters'', to the point where it almost seems like an attempt to deliberately utilize the concepts of the original series wholesale for a younger demographic:
** A boy using a golden item that hangs from his neck is able to utilize the power of a spirit to help him duel. [[Anime/YuGiOh Sound familiar?]]
*** Worse still, the spirit has some form of amnesia and is on a quest.
** The World Duel Carnival tournament is almost identical to Duelist Kingdom as well. The Heart Pieces are almost exactly like the Locator Cards from Battle City.
* ItWasHisSled:
** [[spoiler: "Shingetsu" is actually the human form of Vector, who was manipulating Yuma and the others the whole time until TheReveal.]]
** [[spoiler:Shark and Rio are Barians. Not even the official website for the ''[=TCG=]'' tries to hide it, with the blurb for the [[https://www.yugioh-card.com/en/products/led9/ Legendary Duelists: Duels From the Deep]] set outright saying that Shark and Nash are the same character along with being the leader of the Seven Barian Emperors.]]
* JustHereForGodzilla: There are a number of examples, but Shark was the first and the most famous example, with many people watching ''ZEXAL'' for him instead of Yuma.
* MagnificentBastard:
** [[IncorruptiblePurePureness Eliphas]] is the God of the Astral World who sent Astral out on his mission. Believing absolute order to be the only way for his world to survive, he tries to have his people who created him [[AscendToAHigherPlaneOfExistence Rank-Up]] to combat the Barian World. When Yuma intervenes and challenges him to a duel, Eliphas makes full use of Shining Draw to give Yuma his biggest challenge yet. Upon losing said duel, Eliphas becomes more flexible and comes to accept ThePowerOfFriendship. [[spoiler:During the duel against Don Thousand, Eliphas takes Astral's place in a HeroicSacrifice, tossing him Rank-Up-Magic Astral Force and entrusting the future of the Astral World to him.]]
** [[spoiler:[[WellIntentionedExtremist Nasch]], formerly known as [[RivalTurnedEvil Ryoga "Shark" Kamishiro]], reassumes his identity after regaining his memories. Wanting to protect the Barian World at all costs, he leads the Barian Emperors' assault to wipe out Yuma and his friends. After getting caught in Vector's snaring trap and witnessing the deaths of Durbe and Merag, Nasch breaks free and defeats Vector, [[XanatosSpeedChess surpassing the latter's many tricks]]. Nasch teams up with Yuma shortly afterwards to defeat a common enemy in Don Thousand, being granted the latter's powers after they win. He then uses those powers to engage Yuma and Astral in one of the franchise's most climactic showdowns, only losing due to circumstances that he couldn't have known about. Never letting go of [[TrueCompanions his reasons to fight]], Nasch says goodbye to Yuma and Astral before dying, calling them his two best friends.]]
** [[spoiler:[[TheUnfettered Astral]] is the [[PostFinalBoss final opponent]] that Yuma faces to secure his desired happy ending. Believing the Barian World to be the root of all chaos, he intends to use the Numeron Code to wipe it from history, even if its inhabitants aren't necessarily evil. Yuma challenges him to a duel for the fate of the universe, where Astral shows just how [[WorldsBestWarrior versatile he can be with all of his memories and Numbers restored]]. Understanding how mentally broken Yuma is in the aftermath of recent battles, Astral becomes a WarriorTherapist to help him recover from his trauma. When Astral loses the arduous duel, he spares the Barian World and its people, hoping to find another way to maintain peace.]]
* MemeticMolester:
** Jin, due to his insane stalkerish obsession with Kaito his dialogue when interacting with the Numbers Club, and his general appearance.
** Kaito himself went memetic on at least one forum after some of his... expressions in Episode 22.
** IV quickly reached this point, mostly because of his obsession with "fanservice" and inflicting it on everybody he meets, whether they want it or not. Tron also raised a few eyebrows with his torture of Haruto in episodes 41-43, which he really seemed to be enjoying far more than he should.
** Number 96: Black Mist has definitely earned this reputation, thanks to him using his [[TentacleRope tentacles]] to restrain Yuma and Astral on separate occasions, laughing like a maniac, and his wide array of creepy facial expressions.
* MemeticTroll: ''Vector''. Aside from his actions described under MemeticMutation, there's also his stunt in his duel with [[spoiler:Nasch, where he pretended to have turned to good and then revealed that it was all a trick. Fortunately, Nasch was too smart to be fooled]].
* MoralEventHorizon: Don Thousand [[spoiler:in order to ensure his revival, he traveled the world and selected seven humans who had connections to the Legendary Numbers, which had sealed most of his power. Not too bad right? Look at his methods for doing so. As an example, he brainwashed Alito's best friend and the ruling court to execute Alito, something that everyone had managed to notice, and just before Alito was executed, Don Thousand altered his memories to make it seem that he had been heartlessly killed, instead of being framed by a GodOfEvil. The end result was filling Alito with so much hatred, he was revived as a Barian. Then look at what happened to the other Emperors. Don Thousand essentially ruined their lives all to fuel his comeback, which also ended up tearing up nations and killing large numbers of innocents. Oh, and this includes being responsible from turning ''Vector'' of all people from a decent guy into the monster he is now.]]
* {{Narm}}: Has its own section on the [[Narm/YuGiOh franchise's page]].
* NightmareFuel: [[NightmareFuel/YuGiOhZEXAL Has its own page]]. Despite being one of the LighterAndSofter entries in the franchise, at least at first, it's still ''Yu-Gi-Oh!''
* NightmareRetardant: Vector's gloating can approach this, slightly less so in the dub surprisingly.
* OlderThanTheyThink: The idea that Duel Disks can be used for communication actually appeared first in ''5Ds'' as a plot device in Yusei's Duel Disk as a way for him to clear Aki's name for her involvement in Toby's murder by tricking [[spoiler:Divine]] into admitting it and broadcast it to Misty.
* OneSceneWonder:
** Semimaru/Erazor for being the only one of the Fearsome Four to be a legitimately terrifying villain. Even Mr. Heartland finds his methods over the top.
** [[spoiler:Astral in Dark ZEXAL mode, which is honestly creepy due to how extremely out of character it is for him, and would still be creepy by normal standards anyway.]]
* PanderingToTheBase: While the franchise is aimed at kids to begin with, the series seems to be deliberately appealing more to the younger kids for having a brighter, more childish art style, a protagonist who's much younger then the previous ones ([[IdiotHero and acts like it too]]), a general LighterAndSofter feel and having a quiz show explaining some of the most basic concepts of the game. Oddly enough, the series also featured many [[CallBack Callbacks]] to ''Anime/YuGiOh: Duel Monsters'', which could be seen as pandering to the original fanbase, or simply adapting the original concepts for a new demographic. However, following III's duel with Yuma, it goes into much darker content. The series is only a SugarBowl on the surface.
* QuestionableCasting:
** Yuma is supposed to be 13 years old, [[VocalDissonance yet his dub voice makes him sound a lot younger.]] It doesn't help when you hear his Japanese voice, though this has the opposite effect and makes him sound a little older.
** Casting Gary Mack as Shark. At first, it sounded very cartoony, almost as ridiculous as Toomey from ''Film/TheLangoliers''. [[GrowingTheBeard He got better, though.]]
* ReplacementScrappy:
** The real Numbers 1-4 are widely loathed in comparison to their so-called "Fake" counterparts, due to being considerably more boring and sharing the exact same effects, even after being finally released in the TCG/OCG.
** E'Rah in the manga for Don Thousand (who was already disliked in the first place). She's generally viewed as one of the most {{Generic Doomsday Villain}}s in the franchise, has a thoroughly uninteresting deck, and shows up out of nowhere during the final duel with Yagumo to hijack the match. [[note]]As it turns out she wasn't even meant to appear, but Miyoshi (the artist) was grumbling about having to draw Kyoji Yagumo, the intended final villain, so much.[[/note]]
* RescuedFromTheScrappyHeap:
** Yuma in the manga is a downplayed case. While he's still a total goofball, he's not as stubborn or [[{{Hypocrite}} hypocritical]] as his anime counterpart, and he doesn't do [[TheMagicPokerEquation Shining Draws]] too much. He also fares better against Kaito in their second Duel and ends up ''winning''.
** Kotori's ''World Duel Carnival'' incarnation is considered immensely superior to her anime, manga or any other incarnation, mainly due to her AdaptationalBadass, her absolutely broken deck and her role of not being a cheerleader to Yuma but an actual contestant of the Duel Carnival (which means she actually duels). [[BaseBreakingCharacter While not completely rescued]], since there are some who are pissed off that an originally useless character became a GameBreaker, her popularity certainly increased thanks to that game.
* RetroactiveRecognition: Both Creator/TasukuHatanaka and Creator/SatoshiHino get to voice [[Franchise/UltraSeries Ultra Warriors]] in the Reiwa Era--with the latter voicing Ultraman Titas in ''Series/UltramanTaiga'', and the former being the titular Ultra of [[Series/UltramanZ the eponymous succeeding season]] after ''Taiga''.
* TheScrappy:
** Kotori is one of the most despised characters in the franchise, mainly because a lot of the time she's a glorified cheerleader just shouting [[SayMyName Yuma's name]] many, MANY times. It doesn't help her case that the fanbase think she's reaching CreatorsPet and SpotlightStealingSquad status due to her appearing in almost every single episode despite sometimes contributing nothing but a MandatoryLine, being featured prominently in openings and endings for no reason but Fanservice, and having merchandise centered around her when other more popular and likable characters hardly get featured. When compared to her predecessor Anzu Masaki/Téa Gardner from the original series, a lot of people actually prefer Anzu/Téa over Kotori despite having similar roles.[[note]]For all the flack Anzu/Téa gets for being a [[CommonKnowledge (supposed)]] friendship-obsessed cheerleader, she did have her own character arc (albeit understated) of becoming a dancer and she was assertive in her loyalty to her friends (even standing up to Kaiba once) despite having only a few duels to her name.[[/note]] She also does not Duel outside of a single episode.
** Tokunosuke is also unpopular since he's a slimy cheat who was too EasilyForgiven and generally causes more harm than good to those around him. He's basically the result of the series taking an {{Expy}} of Insector Haga/Weevil Underwood and trying to make him a good guy, but without really toning down the traits that made Haga/Weevil such a HateSink in the first place.
** Final boss characters in the franchise tend to be fairly unpopular among the fanbase, but Don Thousand seems to be the most disliked. It mostly owes to his fairly lacking motivation, the fact that he absolved all the Barians of their sins by [[spoiler:being behind the StartOfDarkness of every single one, including ''Vector'']] so they could be EasilyForgiven, and his final Duel, which took TheMagicPokerEquation typical to the franchise to heights such that he didn't seem skilled so much as impossibly wanky. His Numeron Deck is also tremendously disliked; the Gates, which were the true Numbers 1-4 all have the same effect and are viewed as less interesting than the Fake Numbers 1-4 seen earlier, in addition to becoming very potent after being released in the OCG, while his Number 1000 monsters are disliked for their uninteresting designs and ridiculously overpowered effects and ATK that break the rules of the game.
* ScrappyMechanic:
** Shining Draw is ''massively'' unpopular amongst the general fanbase, who consider it to be little better than cheating. In defense, the villains are often just as bad, but cheating or overpowered villains is nothing new in the franchise, and Yuma is the only protagonist to consistently respond by using it. Compounding the issue is that it further fuels his deck's overcentralizing on Number 39, and that almost all of the cards he first used via Shining Draw (the only exceptions being Numeron Force and Tornado Bringer in a blink-and-you'll-miss-it cameo) stayed strictly in the category of "[[AssPull one-off cards he used to win just that one duel and never used again]]" - contrast to, for instance, [[Anime/YuGiOhArcV Yuya's Pendulum Magicians]] or [[Anime/YuGiOhVRAINS Yusaku's Storm Access monsters]], which they actually kept in their decks and incorporated into later strategies.
** A common effect later in the series was allowing a monster to be treated as more than one Xyz Material. This generally didn't sit well with the fandom, as it stunk of lazy card design and was an anticlimatic way to summon an Xyz monster, especially when all of the cards with this effect were altered to summon other monsters in the OCG.
* SignatureScene:
** Kaito's introduction episode where he casually ''stops time'' and eviscerates Yuma in a duel.
** Yuma and Astral doing their first Zexal Morph and making C39: Utopia Ray.
** Kaito and Yuma vs Trey and Quattro, ending with Kaito's first summon of Neo Galaxy-Eyes Photon Dragon.
** Kaito and Mizael's final match happening ''on the moon,'' while seeing him gain his own Number in Number 62: Galaxy-Eyes Prime Photon Dragon.
** Yuma and Astral's final duel, particularly Yuma creating his own Number in Future Number 0: Utopic Future as the capstone to his character arc.
* TheyChangedItNowItSucks: Some people who were fond of ''Anime/YuGiOh5Ds''' DarkerAndEdgier tone didn't like the characters or plot...though when the series got its dark moments, they hit quite hard.
* TheyWastedAPerfectlyGoodCharacter:
** Rio is introduced with a badass personality and an excellent dueling debut, but doesn’t do anything relevant to the plot other than serving as Shark's motivation and aiding Yuma when he was attacked by an army of Barian-possessed student. Even her [[spoiler:FaceHeelTurn has little impact due to lumping her in with the other Barians]] and Shark overshadowing her the entire time. It doesn't help that not long after into said [[spoiler:FaceHeelTurn, Vector kills her and Durbe]].
** Anna was well-liked for her badassery, attractive appearance, and CrazyIsCool tendencies, in addition to her unique deck. Unfortunately, not only does she only show up once an arc at best, but these appearances tend to be [[ContrivedCoincidence Contrived Coincidences]].
** Luna from the manga. A female Number Hunter who ropes Shark back into the fight with a decent duel, knew Doctor Faker and the Tenjo brothers, and has a badass moment where she saves Shark and Yuma from Kaito. That's really about it aside from being MsExposition, despite Miyoshi and Yoshida noting that she would be one of the rare female duelists.
** Tetsuo has a good enough introduction, especially as he averts this trope from his initial concept where he was just one of Yuma's bullies ala Ushio, and he has his excellent duel with Black Mist and some well-done WhatTheHellHero moments (in contrast to Takashi), being much more grounded compared to Yuma. Then he and Takashi get [[TheWorfEffect Worfed]] by IV, putting him out of action until ''ZEXAL II'', where he doesn't fare much better and his crush on Rio is barely explored (although the removal of their duel may have been due to ExecutiveMeddling).
** Kotori may be TheScrappy, but a major contributor to this is despite having a very large amount of consistent screentime, nothing was ever ''done'' with her character outside of just being support to Yuma. There were some glimmers and hints of concepts that could've been done with her, one idea somewhat early on, and shown in the second ending, is her secretly being terrified of the dangers of Number dueling and watching Yuma having to get hurt. In terms of Number monsters, Number 49: Fortune Tune is often cited as a Number she could have obtained [[AnimalMotifs to fit her bird theming]], and is even a card she uses in video games such as World Duel Carnival, however, she never comes to possess it or any other Numbers in the anime or manga. Ultimately, nothing ever came from such ideas; her relationships with other characters, such as [[TheRival Cathy]] and ironically, Yuma himself, never really grew or changed in the course of the show.
** Mirai is overshadowed by her husband in a similar manner to Shark overshadowing Rio, to the point where it's not hard to wonder why she was even written in as disappearing.[[note]]With ''ARC-V'' having a similar setup for Yuya's father, Yuya's mother fills the roles of Haru and Akari rather than being wasted.[[/note]] It gets worse when you realize that while ''Kazuma's'' disappearance was explained, Mirai's was never brought up, again making one question why she was said to have disappeared as well.
** Charlie is introduced as Kazuma's assistant and had access to a Number as well, meaning that he was in a position where he could've explained more about the story's lore and drop some hints about Kazuma's presence. Instead, he's ultimately an OldFlame of Akari's and disappears after his debut two-parter.
** Kaito fell into this to some degree in ''ZEXAL II'', where now that his arc with Haruto was over, there seemed to be nowhere for his character to ever really go. As such, he appeared much more sporadically and no new ideas were ever displayed with him; though he and Mizael are shown to have a rivalry, it seems much more one-sided on Mizael's part than from any agency on Kaito beyond him being the only one who has the skills needed to take on Mizael's Over-Hundred Number.
* TheyWastedAPerfectlyGoodPlot
** In the anime, the concept of Yuma taking the Numbers used by his opponents is never utilized to its full potential; Yuma relies mostly on Utopia and its upgraded forms, at least when in a duel involving Numbers (which is every duel of any significance), and once he obtains a new Number, chances are good that it will never be used again. It's particularly irritating since he uses Gagagas, which have the gimmick of highly variable levels, but he almost never makes use of their abilities in favor of going straight for Utopia whenever possible. Though the show attempts to play this as Utopia being a card of great personal importance and the majority of Yuma's other Numbers not liking him so it becomes risky to rely on non-Utopia Numbers, it results in his duels becoming decidedly formulaic. In fact, as the series goes on, he actually starts using other Numbers ''less'', with Leviathan Dragon and Terror-Byte being phased out. The manga thankfully averts this trope, while maintaining Yuma's use of Utopia. It helps that Yuma has a smaller Number pool closer to his deck's default levels, making it easier for him to call said Numbers out.
** The ZEXAL power, essentially the source of the series' name and the key to the lore of the story, is never expanded upon. Its origins were never fully explained and it never really existed as anything more than a power-up to give Yuma ZEXAL Weapons to win the duel. Dark ZEXAL is an even greater example of this, as it only appeared in one duel, and it too was never explored as a potential SuperpoweredEvilSide.
** ZEXAL II is shown to have the power of "Shining Evolution" which can reveal the "true form" of a card. This is only used once, changing Rank-Up-Magic Barian's Force to Rank-Up-Magic Numeron's Force. However, Vector gave five other Barian cards to Yuma as Rei, but these cards are never seen again, nor do we ever see their "true forms".
* ViewerGenderConfusion:
** Astral is largely androgynous, so he can be mistaken for female if someone hasn't seen the series.
** III/Trey is so frequently mistaken for a woman that it's common to call him the best girl of the series. The fact that plenty of fanartists like to draw him crossdressing (and he's been cosplayed by girls too) just makes the confusion even greater.
* ViewerNameConfusion: When the anime first came out, most people - including translators - started calling the anime's new summoning method "Exceed", following the pattern of the previous ones (Fusion, Ritual, Synchro). However, that turned to be JapaneseRanguage at work, and the ''real'' name of the method was "Xyz", referring to directional coordinates. Konami even made it a point to show the correct spelling in one interview. That doesn't stop some people from still using "Exceed" though. Additionally, the summoning mechanic is officially spelled with normal capitalization, though that doesn't stop people to this day spelling it in all-caps as "XYZ" (which in-game refers to [[https://yugipedia.com/wiki/A-to-Z a different set of cards entirely]]).
* VindicatedByHistory: For years, ''Zexal'' was the whipping boy of the franchise in the West due to following up on ''5D's,'' Yuma's grating personality and allegations of being a cheater due to Shining Draw, and the slower, lighter pace of the opening episodes before the arc storylines began with Kaito's introduction, leading to it being seen as when the anime shows began to fall off. With time and more fans of the show growing up on the internet, alongside a growing awareness of the second half of the series and its darker, more character-driven plotlines, this has generally faded and ''Zexal'' nowadays has a large number of fans in the west. Notably, this only really applies to the Western fandom- [[GermansLoveDavidHasselhoff the Japanese fandom]] adored ''Zexal'' from launch and reports indicate that its reruns on TV were able to consistently beat new episodes of ''Arc-V'' and ''Vrains.''
* WhatDoYouMeanItsForKids: While it starts out with a lighter, more whimsical tone, ''Zexal'' eventually shows its teeth and contains some quite dark imagery and storylines.
** Events often cited as evidence that ZEXAL isn't a kid's show: Tron being an [[spoiler:AbusiveParent towards his children, encouraging or forcing them to hurt or even ''kill'' to satisfy his goals]], Vector's [[spoiler:manipulation of Yuma and subsequent "MindRape"]], Dark/Black Mist/No. 96's [[spoiler:tentacles, which have been used to bind both Yuma and Astral, as well as his general personality, especially after teaming up with Vector]] and episodes 101-102 which feature [[spoiler:a story about a king who executed his people and committed suicide himself, complete with illustrations]]. Then you have 103, where a gladiator is all but shown to have been executed via decapitation.
** As of the sixth arc, it is very clearly no longer a kid's show. [[spoiler:Character deaths are being thrown around almost casually, with 17 characters--among them the Arclight Brothers, Durbe, Rio, Alito, Girag, ''Kaito'', Vector, Mizael, Eliphas, and a number of Yuma's friends and allies from the past--getting killed off before the season even reaches the same number of episodes.]]
* TheWoobie:
** Baby Tragon. Poor critter's been used by Tokunosuke to presumably rig countless duels in his favor. Let's also not forget Baby Tragon is a Rank 1 Xyz Monster (lowest possible rank), has low ATK/DEF stats, and has an effect confined to only supporting allied Level 1 monsters (in other words, useless for the most part). Baby Tragon's card picture even features him having a very sad face. This story ends with a happy ending, though: Baby Tragon jumps up and flies around with joy when Yuma opts to befriend him and properly use him in the on-going duel instead of abandoning/mistreating him like most other duelists. Yuma gets to keep him, too!
** Kaito and Shark are IronWoobie in both the anime and the manga, [[spoiler:IV]] is a JerkassWoobie.
** [[spoiler:Most of the Barian Emperors qualify too, with the revelation that Don Thousand screwed up their pasts and made them Barians just because they happened to be connected to the Legendary Numbers. With Vector's true memories being revealed, he too is a Woobie, but a JerkassWoobie (emphasis on Jerkass)]].
** With [[spoiler:Astral's [[DisneyDeath Disney Deaths]] , Vector's [[TheReveal reveal]], and the events of the final arc]], Yuma came [[AngstWhatAngst so close]] into becoming this.
** The manga's original characters include a few, namely in Hartland's three Theme Park mascots. [[spoiler:All three are [[OurHomunculiAreDifferent homunculi]] created from objects that developed some kind of will: Captain Corn was once a kernel of corn that had lodged in a pirate captain's compass, Thunder Spark from an Electron, and Princess Cologne from an abandoned doll. All three antagonize the heroes under threat of losing their human forms [[YouHaveFailedMe if they lose]], which [[ForegoneConclusion they all do]]. At least Cologne, the Woobiest of the three gets a happy ending courtesy of Yuma.]]
** Kyoji Yagumo from the manga. Orphaned and separated from his little brother Yuji at a young age he became desperate to become a Duel Monsters champion in order to meet his brother again, and succeeded. This is where it got ugly; [[spoiler:turns out his brother got abandoned by his adoptive family and ended up living in a delinquent center with a roommate who happened to resemble him. When said roommate realized that Yuji was related to a "cash cow" he strangled Yuji and took his place. When Kyoji eventually found out he tried to strangle the imposter himself but he was unable to after the imposter repeated the last words Yuji had said ''as he strangled him''. Is it any wonder that being possessed by a deity of despair in combination with those events turned him into a nihilist?]]
* {{Woolseyism}}: [[spoiler:When Kite is dying on the moon in the dub, Dr. Faker tells him that's there's a medical transport on the way. While this can come off as {{Narm}} in the attempt to avert NeverSayDie, the fact that Kite clearly does end up dying (given his spiritual presence later) and Faker's quote immediately afterwards makes it seem like Faker is just desperately trying to reassure his son that everything will be okay.]]
