* BewareTheNiceOnes: Adorable and kind he may be, but he's not a pushover as proven in his duel against Tilla Mook.

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/mana_9.jpg]]

The younger sister of Mahad and the younger twin sister of Atem, and the youngest sibling of the trio. She's one of the best duelists in the You Show Duel School.\\\
Mana plays a "Magician Girl" deck, with her playstyle focusing on letting her opponents attack her "magician girls" to trigger their effects and land a devastating comeback.
----
* TheAce: Is a strong enough Duelist who could rival her twin brother.
* AmazonBrigade: Mainly uses the Magician Girls archetype but she also keeps a copy of Dark Magician [[spoiler:and Quintet Magician]].
* AttentionWhore: Mana does love the spotlight, in contrast to her twin brother.
* BadassAdorable: She's adorable and she can kick your ass without breaking a sweat.
* BewareTheSillyOnes: Yes she may be a GenkiGirl with a love of Kuribohs and also a hugger...but she's still a strong duelist with a powerful beatdown deck and is SmarterThanTheyLook.
* BlackMagicianGirl: You're looking at the (somewhat) TropeNamer here as not only is her deck the "Magician Girl" archetype, one of her monsters is Dark Magician Girl but it's implied that she ''herself'' has magical abilities.
* BloodKnight: She loves a good duel and has gotten bored with the people she fights. That is, until her loss to Serena and even then she's so happy to find a challenge.

* TheGlomp: She loves hugging others. She even tells Serena and Sora that "she's a hugger" before she embraces them.
* GoodIsNotSoft: Despite her kind and girly personality, she's far from weak or unintelligent.
* GracefulLoser: She takes her loss against Serena with stride, as the latter was the first Duelist who really challenges her.
* IdenticalStranger: Her Dark Magician Girl and Apprentice Illusion Magician look exactly like her which many people lampshade.
* NightmareFuel: An InUniverse example, as her use of both Fusion and Xyz monsters against Serena, causes this reaction from Sora, who was indoctrinated with a FantasticRacism against Xyz Duelists.
* OlympusMons: [[spoiler:Quintet Magician]] which she uses against Serena.
* RelatedInTheAdaptation: She, Mahad, and Atem are all siblings in the fic.
* SiblingYinYang: She and Atem couldn't have been more different than day and night. When Sora asked if Atem is anything like Mana, everyone around him laughs at such a comparison.

* AdaptationalNiceGuy: In the original manga, he started off as TheBully to Yugi before later becoming his close friend when the latter sticks up for him and Tristan against [[StarterVillain Ushio]].

* BigBrotherMentor: To Yuya, helping him move on from seeing his father just vanish one day.
* BigDamnHeroes: He saves Yuya in their first meeting from bullies who want to harm him due to Yusho's disappearance.

!!Industrial Illusions
An entertainment company run by Maximillion Pegasus that specializes in creating the Duel Monster Cards and Archetypes.

[[folder:Maximillion Pegasus]]
!!Maximillion Pegasus
!!!'''Archetype''': Toons
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/maximillion_pegasus.png]]

The uncle of Mahad, Atem, Mana, and the current President and CEO of Industrial Illusions.
----
* BunnyEarsLawyer: Make no mistake that Pegasus is eccentric but he's also a very smart and successful CEO and is quick to help Yuya make a business deal that actually benefits the boy.
* CoolUncle: To his nephews and niece, as seen in chapter 4.
* DubNameChange: He's known by his dub name instead of his original Japanese name, ''Pegasus J. Crawford''.
* {{Manchild}}: A given. When he meets with the limo driver he states that the in-flight entertainment bored him...and quickly gets excited when he learns there's a copy of ''Yotsuba'' in the limo.
* RelatedInTheAdaptation: He's a the adopted uncule of Mahad, Atem, and Mana in the fic.
* StealingTheCredit: A rare ''positive'' example. Knowing that Yuya would be called a cheater for creating an entirely new summoning mechanic, Pegasus offers the boy to take credit for inventing Pendulum Summoning and saying that Yuya was testing it, while giving Yuya and his mother a share of the profits.
[[/folder]]

!!Leo Corporation
A company founded by Leo Akaba that specializes in Duel Monsters and Duel Disk as well as creating various Duel Schools known as Leo Duel School. After Leo disappeared and abandoned his family his son Reiji took over and became the new CEO.

[[folder:Reiji Akaba]]
!!Reiji Akaba
!!!'''Archetype''': DD/DDD
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/reiji_akaba.png]]

A prominent duelist and a CEO of Leo Corporation. He has a sour grudge towards his father Leo Akaba for abandoning him and his family and aims to defeat his father and Academia in order to stop his evil ambition.
----
* AdaptationalHeroism: While Reiji is no less capable of committing as many morally questionable acts to achieve his goals as his canon counterpart, his early AmbiguouslyEvil acts of "acquiring" Yuya's Pendulum cards are AdaptedOut thanks to Pegasus StealingTheCredit for the creation of the Pendulum Summoning mechanic in a contract with Yuya and his mom to prevent the boy from getting accused of cheating in his duel against Strong Ishijima, and receiving financial compensation.
* AdaptationalIntelligence: Reiji's plans for creating the Lancers are more thought-out as he intends to have another group of them bring aid to the Xyz Dimension.
* AgentMulder: Reiji is more open-minded about the supernatural and unknown this time around, believing that some other force is what was responsible for Yuya's Pendulum cards.
* DemotedToExtra: In the canon anime, he was Yuya's main rival and the BigGood of his series. Here, he's one of the supporting characters and doesn't get much screen time when compared to his original version, since the story mainly focuses on Ray, Zarc, the Dragon Boys, and the Siren Girls.
* SmartPeopleWearGlasses: Sports a pair of red square-rimmed glasses and is a ChildProdigy who's capable of being TheChessmaster when it comes to business and dueling.
* TheSpock: He is very analytical and logical most of the time.
* TheStoic: He rarely smiles after his father abandoned him and displays a calm, collected, and no-nonsense attitude.
* ThirdWheel: Although he isn't really friends with Yuzu and Yuya, he does felt rather awkward when seeing the two interact with each other in chapter 12.
* YouRemindMeOfX: Chapter 10 has Pegasus note that Reiji reminds him of Kaiba due to him being TheSpock. Humorously, this is fitting since Reiji was also a [[CompositeCharacter Composite]]/ContrastingSequelMainCharacter of Kaiba in canon.
* YoungAndInCharge: He's only 16, but is the current CEO of Leo Corporation.

!Xyz Dimension
!!The Resistance
The remaining Xyz duelists who haven't been captured by Academia; are the last remnants of a world that's gone to hell due to dimensional invaders. The Xyz dimension was originally a peaceful place to live in before they were attacked without warning. After repelling against most of the Obelisk Forces, duelists of the Resistance were able to procure the same technology as their enemies and can now inflict real damage on their opponents and sealed them away into cards.

[[folder:Shun Kurosaki]]
!!Shun Kurosaki
!!!'''Archetype''': Raidraptor
[[quoteright:270:https://static.tvtropes.org/pmwiki/pub/images/kurosaki_shun_3.jpg]]

Shun Kurosaki, along with Yuto, is one of the survivors of the invasion on the Xyz Dimension, as well as a member of Resistance. Originally a kind, if a somewhat stoic person, the invasion took its toll on his psyche. What makes this worse is learning that the true reasons why his home was destroyed and his younger sister Ruri, being planned as a "sacrifice" along with his best friend Yuto, being intended to get killed off by The Professor. He later joins up with Ray as her "knight" to ensure the safety of his loved ones and to make Academia paid for their transgressions.\\\
Shun uses a Raidraptor deck, which is made for swarming Winged-Beast-Type monsters to Xyz Summon monsters with low base-ATK, but powerful effects. He also has many Spell and Trap Cards that can counter various situations and exploits his Rank Up spells to evolve his Raidraptors into more powerful forms.
----
* AdaptationalAngstUpgrade: In the anime, Ruri being captured by Yuri causes Shun to really start [[SanitySlippage losing it]], and soon became a HeWhoFightsMonsters AntiHero. When being enlightened by the AwfulTruth of the Dimensional War along with the fact that his sister and best friend are to be sacrificed and killed respectively, his thirst for vengeance and hatred goes past the point of no return.
* AdaptationalNiceGuy: Compare to his canon counterpart, who's already a {{Jerkass}} HeWhoFightsMonsters AntiHero at the start of the story, Shun's relatively "nicer" here due to Ruri never having to be kidnapped by Yuri. Furthermore, his BigBrotherBully and ControlFreak tendencies of his sister are relatively toned down here.
* AdaptationalVillainy: At the beginning of the canon anime, he was already a GoodIsNotNice AntiHero [[JumpingOffTheSlipperySlope skirting onto the edges]] of a NominalHero. Here, he fully becomes an AntiVillain since he's helping [[VillainProtagonist Ray]] to ensure the safety of his sister and best friend.
* AntiVillain: After chapter 13, he falls into this role since, despite helping the revival of Ray and Zarc, his goals firmly lie in protecting his sister and best friend, helping the ones they care about, and rebuilding their home after it was laid waste by the Academia Forces.
* BadassLongcoat: He wears a long blue-purple coat and looks tough with it.
* BigBrotherInstinct:
** Ruri may not have been blood-related, it doesn't stop him from being a very doting brother if a little overprotective. So much as he's willing to make a pact with Ray to revive her and Zarc as long as she ensures that Ruri will be still alive in the end.
** He also extends this to Yuto and included his safety as well in his pact with Ray.
* ChessMotif: The Knight, as he serves as Ray's agent in chapter 13.
* CyberneticsEatYourSoul: Metaphorically; his Raid Raptors monsters resemble robotic avian predators, which symbolizes his desire to protect his sister and PayEvilUntoEvil on his foes. However, his devotion to his sister is what Ray recognizes as a good trait.
* DarkIsNotEvil: Played with. Despite his dark attire and joining up with Ray to revive her and Zarc, Shun cares more about protecting his loved ones and hurting those who try to harm them.
* DeathFromAbove: A recurring motif of his Raid Raptors, with Revolution Falcon burying the Obelisk Forces under a hail of bombs in his nightmare.
* EvenEvilHasStandards: Despite being willing to commit morally unconscious acts in order to protect his sister, best friend, and homeland, Shun is quite disgusted by learning how petty Leo's motives are in order to revive his daughter.
* FantasticRacism: Considering what the Obelisk Forces had done to his home, he hates Fusion Summoning. Although this is rather downplayed thanks to Ray and his sister, focusing his hatred on Academia rather than fusion users in general.
* HeterosexualLifePartners: With Yuto, as the two are best friends from thick to thin.
* KarmicJackpot: A villainous example. His love for Ruri is recognized by Ray, who's very happy that her counterpart had such a loving family member and would anything to protect her and their friends. This leads to him being gifted by both Ray and Zarc with his own powers and gain new cards as well.
* KnightTemplarBigBrother: He will do ''anything'' to make sure that Ruri is alright, and he extends to Yuto to a lesser extent. It's also what causes him to ally himself with Ray and Zarc in the first place.
* MagicKnight: A pretty good duelist in a world where duel monsters can be implemented with real magic and is a skilled hand-to-hand fighter capable of taking down several enemies at once. This is much more apparent with Ray and Zarc empowering him with his new cards.
* LoveMakesYouCrazy: His love for his sister Ruri makes him very erratic in his willingness to protect her, which Ray finds endearing.
* LoveMakesYouEvil: He later joins up with Ray into reviving her and Zarc to protect Ruri.
* NoHoldsBarredBeatdown: It's what he ''intends'' to do to The Professor, as his brief fantasy shows, it involves grabbing the man by the throat and bashing his skull against his own throne repeatedly. [[AdaptationalKarma And unlike canon, it's probably going to happen compared to his almost punch at the man]].
* NotSoStoic: He drops his stoicism whenever Ruri or his allies' lives are at stake.
* PowerLossDepression: {{Inverted|Trope}}. As he gains power by accepting the two cards gifted to him by Ray and Zarc, he becomes much more lively.
* TheStoic: He becomes very cynical and emotionless after Academia invaded his home.
* ThreeAmigos: He has this dynamic with his sister and best friend after the three of them are on the same page in chapter 13. This leads to Sayaka feeling uneasy by how the three "move and spoke with a strange union and synchronicity".
* TookALevelInBadass: In chapter 13, he gains powers like his sister and best friend, and his deck gains two more cards from Ray and Zarc respectively.
* TookALevelInCheerfulness: He became very depressed and stoic after Academia destroyed his home, but after accepting two cards gifted to him by Ray he becomes more lively.
* YouAreWorthHell: "The only truth I know is that Ruri is my sister, my family. Nothing will change that, nothing could make her any less important to me."

!Synchro Dimension
!!The Enforcers/Monarchs

Four duelists from the Commons banded together to bring peace between them and the Tops. Jack was originally sent into the Friendship Cup to become King, but after he was influenced by Roget, his fellow Enforcers intervened and placed Yusei as the head, and the four to help heal the divide between the two classes.

[[folder:In General]]
* AdaptationalBadass: All of them have some sort of strange power to them: Yusei controls electricity, Jack controls fire and Kalin can manipulate shadows. This is even noted in-universe as Armstrong, Grady and Carly note that there were rumors that they had special abilities.
* AdaptationalSexuality: Compare to their heterosexual canon counterparts, all four of them are in a four-way romantic relationship with each other.
* BigGood: To the entirety of Neo Domino City, as they manage to bring order to the society by abolishing the City's [[SocialDarwinist highly competitive culture]] and [[SpannerInTheWorks threw a huge wrench into Roget's plans]].
* DarkIsNotEvil: They either have dark-looking monsters or appearances, and they also have edgy-sounding nicknames, but they're all on the side of good.
* TheDreaded: ''All of them'' are this to most of Neo-Domino. To give an example, seeing Kalin enter Bootleg -- to get Yanagi away from Armstrong -- has an ''everyone in the bar'' run away in terror and for Grady and Carly to realize they're ''fucked''.
* DubNameChange: WordOfGod kept their dub name for the group instead of the original Japanese one (Team Satisfaction), as she states that the Japanese name sounded stupid.
* HeroOfAnotherStory: Their story of how they manage to foil Roget's plans by taking back control of Neo Domino City and abolishes the City's highly competitive culture, is a tale worth telling.
* MythologyGag: In their backstory, they created a safe haven known as "Satisfaction Town", referencing the Crashtown arc.
* {{Polyamory}}: All of them are a foursome of wholesome satisfaction.
* RedBaron: All of them have badass titles: Kallen is "The Shinigami", Jack is "Hell's Harbinger", Yusei is "Stardust Rider"/"King of Neo Domino" and Crow later gets "Black Omen". Crow even lampshades the fact that everyone else got cool names before him. Collectively, they're called the "Lords/Monarchs of Neo Domino".
* StraightGay: None of them display any stereotypical behaviors of homosexuals, as their personalities are relatively the same as their canon counterparts.

[[folder:Yusei Fudo]]
!!Yusei Fudo
%%!!!'''Archetype''': ???
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/yusei_fudo_2.png]]
The leader of the Enforcers, current champion of the Friendship Cup and King of Neo Domino.
----
* InSeriesNickname: He's affectionally called "King" by his fellow Enforcers.
* MustHaveCaffeine: Inverted. Yusei is '''not''' allowed to have caffeine as it makes him even ''more'' of a {{workaholic}}. The last time this happened, it took Jack, Crow, and Kalin to fuck him to wear him down. The reader sees what happens first hand after Randsborgh accidentally leaves a cup out for Yusei. It's apparently so bad that Jack won't even risk giving Yusei an ''iced tea''.
* OnceDoneNeverForgotten: The "Yusei with caffeine" moment with even Yusei complaining it was just one time.
* ProperlyParanoid: Was worried about the trouble Yanagi could get into when his fellow Enforcers reassured him the old man would be fine. Unfortunately none of them counted on Armstrong...
* ShockAndAwe: Has electrical abilities although they haven't been on display yet.
* TranquilFury: When significantly pissed off, he's capable of making ''Jack Atlas'' fear for his life.
* {{Workaholic}}: Yusei will work himself to death if it means making sure others don't have to suffer. It gets to the point that ''Jack'' has to pull him away and make him get some sleep. This is also very common as the other Enforcers have had to pull him away from work, whether it's papers, laptop or just dragging him from tuning up their D-Wheels.

Former king of the Friendship Cup and a member of the Enforcers.
----
* AdaptationalPersonalityChange: He's more humble than he was in canon. Justified in this case as he has his Enforcers to help keep his ego in check.
* GoodWearsWhite: He wears a white jacket and he's one of the Enforcers.
* LethalChef: Cannot cook to save his life. The idea of him making something for Yusei to eat elicits an AnythingButThat reaction from the latter.
* OnlySaneMan: Acts like this when Yusei works himself too much, having to drag him away to get some rest.
* OOCIsSeriousBusiness: It's noted that whenever Jack calls Yusei "King" that it's in a much more affectionate tone than when Kalin or Crow says it.
* PlayingWithFire: Implied to have fire abilities with security guards once having to put out fires that they had no idea where they came from.
* PuppetKing: He was this to Roget and the City Council in his backstory until Yusei manages to defeat him.
* RunningGag: Always likes to bring up Lady Fate to the point that Yusei states that Lady Fate hates him. The author notes lampshade this by stating that no, Lady Fate doesn't hate him; she just likes screwing around with him.
* TrademarkFavoriteFood: Still loves his instant ramen and coffee.

!!Crow Hogan
!!!'''Archetype''': Blackwing

----
* InsultBackfire: When Armstrong says that he can't tell why Yanagi is needed, Armstrong states that it would go over his [Crow] "boyfriend's little head". Crow retorts that, aside from Jack, Armstrong has to be more specific since he has ''three'' boyfriends.
* OnlySaneMan: Compared to his fellow Enforcers, he's the most level-headed of the group, even lampshading why he doesn't get some badass title for his own.
* ThisIsGonnaSuck: After the wild goose chase against Armstrong and Yanagi and seeing news crew asking what happens, Crow realizes that ''Yusei'' has just seen all of this and is going to blow a gasket.

* AdaptationalHeroism: Was a Dark Signer in the anime, but a Crimson Signer in the fanfic.
* AdaptationalNiceGuy: Does ''not'' have his AxCrazy tendencies from the anime.
* AlliterativeName: '''K'''alin '''K'''essler.
* CastingAShadow: Is capable of summoning darkness, as he demonstrates with Carly. He also uses the Infernity archetype which is filled with DARK monsters.
* DubNameChange: Uses his dub name instead of his Japanese one (Kyosuke Kiryu) which makes him stand out to the other Enforcers keeping their original names.
* NamesToRunAwayFromVeryFast: Do ''you'' want to get on the bad side of the guy called ''Shinigami''?!
* ThisIsGonnaSuck: After learning about the Crimson Dragon Crusaders and how Armstrong led Crow onto a goose chase that was seen ''on live television'', all he can do is slam his head on a table knowing that Yusei is going to kill them.

!!The Crimson Dragon Crusaders

-->''"This is a new chapter in the history of the Randsborg name for we [Randsborg, Grady, Armstrong, Yanagi and Carly] are now a mighty group who are off to solve the mysteries of the Crimson Dragon. We have now become...the Crimson Dragon Crusaders!”''

Five duelists from the Synchro Dimension came together after seeing Rin dueling Professor Frank and Akiza's Crimson Dragon mark on her arm, diving into the mysteries involving their dimension.

[[folder:In General]]
* AscendedExtra: All five of them were secondary characters who had one duel throughout the entire series (barring Carly who had three). Grady gets this the most since he had little to no personality traits at all (due to being brainwashed at the time).
* FiveManBand:
** TheLeader: Gill Randsborg
** TheLancer: Dick "Grady" Pitt
** TheBigGuy: Mr. Armstrong
** TheSmartGuy: Tenzin Yanagi
** TheChick: Carly Nagisa
* HeroOfAnotherStory: Of the Synchro Dimension side of the fic, one where it involves the lore of the Crimson Dragon being unrelated to Ray and Zarc's revival, uncovering secrets of the Arcadia Movement, and subsequently learning that they're just one part of a bigger puzzle.
* LastNameBasis: Randsborg, Armstrong, and Yanagi are usually addressed this way.
* TheQuest: As Randsborg notes, their quest is to uncover the secrets of the Crimson Dragon, Zarc, and how Rin and Yugo are connected, and why the Arcadia Movement is so interested in them.
* RagtagBunchOfMisfits: They consist of a knight, an archaeologist, a former member of Security, a street duelist with a fondness of milk, and a [[spoiler:crossdressing]] reporter. Armstrong even lampshades that they're "a little ol' Breakfast Club".
* TheUnchosenOne: Despite their group name, none of them are chosen by the Crimson Dragon. Instead, they're just a group made up of individuals who grew curious about the world around them after witnessing the duel between Rin and Professor Frank.

[[folder:Gill Randsborg]]
!!Gill Randsborg
!!!'''Archetype''': Infernoble
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/jilldelancebeaux.png]]

A duelist who hails from a legendary family of knights. He is the first to bring up the legend of Zarc and the Crimson Dragon to the Crusaders.
-----
* AdaptationalBadass: He used LV monsters called Masked Knights in his only duel while the narration states he uses Infernoble this time around.
* AdaptationalNiceGuy: Was an utter buffoon and believed that Akiza was a real witch in the anime, losing to her in a humiliating fashion. In the fanfic, he acts like the TeamDad for the Crimson Dragon Crusaders.
* AdaptationPersonalityChange: He was WrongGenreSavvy against Akiza in the anime, but here he knows well enough ''not'' to start BullyingADragon against her.
* HairOfGoldHeartOfGold: Golden hair and is a gentleman.
* HeroOfAnotherStory: His family has knowledge not only of Zarc, but also of the Earthbound Immortals and Crimson Dragon. What else have they been hiding?
* KnightInShiningArmor: Wears golden armor and is a chivalrous character through and through. Fittingly, he uses the Infernoble archetype.
* LargeHam: As befitting a knight, he likes to go on flowery tangents.
* NiceJobBreakingItHero: PlayedForLaughs. After he and Yanagi are allowed to bunk with the Enforcers to learn more about their powers, he left a mug of coffee for Yusei...not aware that Yusei ''must not have caffeine'' and has to see his fellow Enforcers dogpile Yusei before he works himself to death.
* TheNicknamer: Gives each of his fellow Crusaders different titles, "Valiant Grady", "She of Fair Eyes", etc.
* PlayingWithFire: He is said to have used Infernoble monsters, which are FIRE type.
* StrokeTheBeard: Does this as a {{Character Tic|s}} when in deep thought (even though, as the image shows, he doesn't have one).
* YeOldeButcheredEnglish: Speaks in this as part of being a knight.

* AdaptationalPersonalityChange: Had little to no personality in the anime and his ''only'' personality came from being a brainwashed goon for Yusei to duel. Here, he's the level-headed member and he's known to be concerned for whatever Carly is getting into and will protect her if she gets into trouble.
* AwesomeByAnalysis: Knew that Xavier Maxa was [[spoiler:Carly in disguise]] by picking up on his habits: stating that being near Armstrong was like living in the Pits (Carly's boss was Mr. Pitt) and bringing up Blue Eyes Mountain Coffees (an expensive brand that Carly knew Jack liked in the anime)
* CrazyPrepared: By the time Rin vs Akiza happens, he made it a habit to carry a parka and coffee since he knows that Rin's ice powers are not to be trifled with.

* DarkIsNotEvil: Wears black and red and has black hair, but he's level-headed and has no malicious bone in his body.

* YouCalledMeXItMustBeSerious: Xavier calling Grady by his real name causes him to step back in fear. [[spoiler:Especially since Grady knows that it's Carly saying that to him.]]

* AdaptationalNiceGuy: Was a HateSink in the anime, to the point that ''Goodwin'' was disgusted by him. Here he's a bit of a grump and would rather ''not'' get involved with the chaos of the Synchro Dimension, but joins in when things start to get too deep. And his antagonism with Yanagi in the story is more on poor communication than him being a jerk.

* EveryoneHasStandards: He's an unpleasant jerk to be around but he has low esteem for [[BigBad Jean-Michel Roget]] and thinks that [[SmugSnake Professor Frank]] brainwashing Rin (a ''14-year-old girl'') is low. In fact, he personally was going to stop the duel himself if it continued. He also showed concern when Akiza's arm started to glow with her Crimson Dragon Mark.
* HoistByHisOwnPetard: The details of his duel against Xavier are vague but all we know is that his milling strategy ended up backfiring on him when Xavier's Fabled Leviathan was destroyed and he was able to retrieve three Fabled monsters from the graveyard (one of them being The Fabled Catsith).
* MisterExposition: He knows the most about Rin and Yugo and later reveals that he has heard rumors about [[spoiler:Security having Polymerization and Fusion Monsters]].
* NiceJobBreakingItHero: Nearly gets Grady and Carly into loads of trouble when he antagonizes Yanagi ''without'' explaining why he was chasing after the old man. Not helping that Crow and Kallen were ''also'' chasing him down since they knew each other in the past. He realizes his mistake when he learns how Crow has a Crimson Dragon mark.
* PoorCommunicationKills: Chases after Yanagi ''without'' explaining that he needs Yanagi's info about the Crimson Dragon nearly got him, Grady and Carly into loads of trouble when Kalin and Crow arrived and ''also'' needing Yanagi's help)

* TheGlassesComeOff: Removes them when he tells Randsborg to stop living in the Middle Ages and think that all women are either princesses to be rescued, witches to be executed or lost souls who need to see the light.
* LightEmUp: Used the Fabled archetype which are all LIGHT monsters.
* LightIsNotGood: Zigzagged; the Fabled monsters are a bunch of a-holes, as Xavier explains to Randsborgh, but Xavier/Carly is a good-hearted person.

!Fusion Dimension
!!Academia

The Fusion Dimension's Duel Academia, who make it their life's mission of attacking other dimensions and sealing their victims into cards. A majority of people from this dimension are quite sadistic, treating their heinous actions as a "hunting game" and laughing about the destruction that they cause.

[[folder:Leo Akaba]]
!!Professor Leo Akaba/The Professor
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/leo_akaba.png]]

Ray's father, who three years ago went to the Fusion Dimension, where he became the Professor, the head of Academia. He is the instigator of the interdimensional war with the intent to conquer all dimensions and unite them under his command.\\\
The Professor originally hailed from the Original Dimension where his technology gave Duel Monsters the ability to interact with reality itself, as well as invoking in them actual feelings. This backfired spectacularly when he inadvertently helped create the "Demonic Duelist" known as Zarc and the fusion of all his dragons... with his daughter Ray joining him as they declared war on humanity.\\\
Thus the entire reason for starting the war in the first place is his ill-guided attempt to "unite" the dimensions once again and revive his daughter Ray, who he believes Zarc "corrupted" into joining him.
----
* AdaptationalJerkass: Compare to the canon series, this version of Leo was quite neglectful of Ray and is implied to be very controlling of her prior to the Original Dimension's destruction, adding another layer to his already questionable sanity and delusion.
* ArchnemesisDad: To both Ray and Reiji.
* BadassBookworm: He's not only a multi-disciplinary scientist but is capable of running a military school as its headmaster.
* BaldOfEvil: He's completely bald in the current time, and is willing to launch an unprovoked war against the other Dimensions to resurrect a child who simply doesn't exist beyond his own delusion.
* ControlFreak: He was this to his daughter in the Original Dimension, and it still sticks up to this day.
* TheCorrupter: Ever since he established control in the Fusion Dimension, he indoctrinate most of Duel Academia's students into genocidal soldiers and encouraged Yuri into the monster he's well known to be at the beginning of the story. This makes his grudge against Zarc for supposedly "brainwashing" his daughter all the more ironic.
* DramaticIrony: The entire plot of the story can all be traced back to his own ''parental flaws'', and is only going to be causing more problems for him in the long term.
* EvenEvilHasLovedOnes: For all of his flaws, all the things he does is to attempt to be reunited with his daughter, Ray, after her soul was split across the four dimensions. This is deconstructed, however, as it not only causes him to commit heinous actions to achieve his goal of reviving her, it also showcases his ParentalObliviousness to Ray.
* {{Hypocrite}}: He has a personal grudge against Zarc for not only destroying the Original Dimension but is also fully convinced that the latter brainwashed his beloved daughter into becoming a villain. Yet, he's completely oblivious to the fact of the pain he's causing by waging an unprovoked interdimensional war, spent years [[TheCorrupter indoctrinating]] {{child soldier}}s into doing his dirty work, ''and'' is willing to have the Doktor used the Fusion Parasites to brainwash his daughter's four reincarnation/fragments.
* {{Irony}}:
** His neglectfulness and controlling nature for Ray, [[YoureNotMyFather who wants nothing to do with him anymore]], and ParentalAbandonment of Reiji, has led to both children plotting against him. Which is rightfully lampshaded by Serena in her personal chapter.
** If you have already read the hypocrisy of his actions above, then you can already tell that not only does the actions he took makes him NotSoDifferent from Zarc, but also NotSoSimilar as Leo is far ''worse'' for his delusional and controlling behavior.
* NonActionBigBad: He currently sits at his throne in the Fusion Dimension while sending out Duel Soldiers to invade the dimensions.
* NotSoSimilar: To Shun Kurosaki in the canon anime's English Dub. From there, Shun realizes that both of them committed morally unconscious acts in order to get back a family member that they loved and lost; Shun for Ruri and Leo for Ray. Furthermore, Leo's ControlFreak and OverprotectiveDad tendencies here are quite reminiscent of Shun's own controlling and protective behavior for Ruri in the anime. However, that's where the similarity ''ends'' here in the fic, as, unlike Leo's obliviousness and [[LovingAShadow shadow love]], Shun ''genuinely'' loves Ruri and is capable of recognizing her for her own character and choices and doesn't prevent her from having a romantic relationship with Yuto before a disastrous event, who is his best friend and the one other person in his life who he explicitly trusts. [[FridgeBrilliance In fact, this crucial difference is possibly another reason why Ray recruited Shun as her knight and agent besides his devotion to his sister.]]
* ObliviouslyEvil: He completely disregards the pain and despair he causes for others throughout the Four Dimensions simply due to his delusional belief that everyone aside from himself, Ray, and Zarc is not ''real'' as they only exist as "mistakes" due to the fracturing of the Original Dimension.
* OmnidisciplinaryScientist: If you haven't read the long list from the canon series' page, then you'll know that'll it be too long to list here.
* OverprotectiveDad: According to WordOfGod, he never approved of his daughter's friendship with Zarc, but couldn't keep them apart as he was too busy with his work to notice their secret hangouts and relationship. This is fully {{deconstructed|Trope}} as, unlike the usual examples, it's another sign of his ControlFreak tendencies.
* ParentalNeglect: {{Deconstructed}}. Leo and his wife were never really around for his daughter, Ray, and if so, they gave her very little personal freedom. This is what leads to Ray leaning onto Zarc for support, and vice versa as BirdsOfAFeather, and ended up with her joining Zarc into laying waste upon humanity for their bloodlust.
* ParentalObliviousness: Leo Akaba only cares about resurrecting his "perfect daughter" while disregarding her four counterparts as merely "sacrifices", and believing that Ray was ''brainwashed'' by Zarc into joining him in the first place. To put it simply, Ray is [[EvenEvilHasStandards disgusted]] by this delusion and had [[YoureNotMyFather renounced]] Leo as her father ''long ago''.
* UnwittingInstigatorOfDoom:
** His research to enhance Real Solid Vision, which allowed Zarc and Ray to summon and then fuse with their monsters, leading to the end of the original world.
** On that note, his ParentalNeglect of Ray is part of the reason she even joined Zarc in the first place.
** Sending Yuri to kidnap Ray's incarnations, bringing the girls together which jump-starts the plot.
** He started the Dimensional War because of his unthinking selfishness, driving Yuto, Ruri, and Shun to the arms of Zarc and Ray very easily.

!!!'''Archetype''': Ancient Gear
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/obelisk_force_1.png]]

The Obelisk Force is an elite group of Duel Soldiers of Academia.\\\
They often duel in tag, using the advantages and loopholes of the Battle Royale Mode, and take down their opponents with teamwork and burn damage. All of them seem to run Ancient Gear decks, particularly based on the Ancient Gear Hunting Hound.
----
* AdaptationExplanationExtrication: None of their duels are written onscreen in the fic, as WordOfGod stated that she doesn't know how to write a duel in the Battle Royal Format that was in the anime since it doesn't have any clear rules, and a duel with that magnitude needs far more set up. However, the writer has made her own rules and will be using them in a future chapter.
* AlwaysMale: So far, the group doesn't seem to have any female members.
* AncientGrome[=/=]ClockPunk: Like many other Duel Soldiers, they use cards such as Ancient Gear Knight and Ancient Gear Hunting Hound.
* BegTheDog: They won't hesitate to beg their "prey" for their lives in case they actually lose a duel. If anything, it only makes their own defeat and death more cathartic InUniverse.
* BloodKnight: {{Subverted|Trope}}. They'll revel in a good fight against the "Xyz Scum" if only to make their hunting games more enjoyable once they'll defeat and card them as their fallen prey begs for mercy. But when things go south and they ''actually'' lose the duel, they won't hesitate to run away in fear or ''beg their'' '''''prey''''' ''for mercy''.
* BullyingADragon: As seen in their off-screen 3-to-1 duels against Ruri and Yuri respectively. It doesn't end well for them either way.
* ColorCodedForYOurConvenience: Their masks have gems of different colors set in them, which is generally the only way to tell them apart. Doesn't make too much of a difference because they're all basically interchangeable, to begin with, but it does make their duels easier to follow.
* {{Combat Pragmatist}}s: They duel in Battle Royal Mode rather than in regular 1-on-1 duel. Since the Battle Royals don't have specific rules, they attack their opponents before those even get their first turn.
* CyberCyclops: Chaos Ancient Gear Giant.
* DirtyCoward: What most, if not all, of them are deep down. They're fine with attacking in numbers and acting all smug while in a position of being a predator. Yet, when they lose in spite of having those advantages, they'll either run away in fear or beg for mercy.
* EliteMooks: PlayedWith. They are the highest-ranking students of Duel Academia, like the lore of ''GX'', and their invasion of the Xyz Dimension involves them defeating and carding many duelists and civilians alike. However, they're only truly a threat due to their [[ZergRush strength in numbers]], overreliance on the Battle Royal Mode, having the initial advantage of AttackAttackAttack. Once those tactics are no longer valid and they end up losing a duel, they either [[DirtyCoward run away in fear]] or [[AintTooProudToBeg beg for mercy]].
* HumongousMecha: They have a Chaos Ancient Gear Giant to use in their decks.
* {{Jerkass}}: So far, every single one of them.
* {{Mooks}}: All of them wearing the same uniforms, wear almost the same [[FacelessGoons masks]], all share the same personality, and all of them seem to run Antique Gear decks. Unfortunately, they are also EliteMooks.
* RedEyesTakeWarning: The red lenses of their masks lend themselves to this effect.
* {{Sadist}}: They feel pleasure from hurting and carding people.
* SmugSmiler: All the time.
* SmugSuper: They can come off as SmugSnake, but they're technically this since they're actually good Duelists by the standards of their home dimension.
* SpoiledBrat: While Ruri describes all of the Academia Duel Soldiers as this, the Obelisk Force is more guilty of this trope, if one knew of how the Obelisk Blue students from ''GX'' are mostly comprised of {{Jerkass}} rich kids and female students regardless of their initial Duel performances (as the Obelisk Blue Dorm is the only student residential area that has working plumbing for female students).
* WeaponOfChoice: Every monster they use is either an Ancient Gear Hunting Hound or one of its Fusion forms.
* ZergRush: Their preferred tactic to duel is by using the Battle Royal Format to overwhelm their opponents, whether it'll be to card their prey in the Xyz Dimension or to bully lesser students in Academia. {{Deconstructed|Trope}} as this also falls into CripplingOverspecialization, as they can get blindsided by an opponent who uses effects that could take down multiple monsters in a single turn.

A group of four Duelists from "different times" who battle against the recently transcendent Gods, Ray and Zarc. It led to the fracturing of the Original Dimension, along with the lives of them being sent throughout the Four Dimensions.

* CompositeCharacter: They took Ray's role as the GreaterScopeParagon against a GreaterScopeVillain from the canon anime.
* FourIsDeath: The four of them battling against the godlike Ray and Zarc causes the Original Dimension to split into the Four Dimensions, as well as them being flung through and separated with no memories of their past lives.
* TheGhost: They're repeatedly mentioned from time to time, but haven't made an appearance nor do we learn of their true identities.
* GreaterScopeParagon: They essentially went against two beings who had already become [[PhysicalGod Physical Gods]], and manages to prevent them from destroying the rest of humanity, leading to the fracture of the Original Dimension.
* HeroAntagonist: They were the ones who oppose Ray and Zarc after the two wage war against humanity as gods.
* MinorMajorCharacter: Very little is known about them throughout the story, but Ray and Zarc know ''who'' the four of them are and have shared it amongst their allies. According to WordOfGod, the revelation of their identities will mark a turning point.
* MythologyGag: A group of Duelists who came from different timelines and band together to stop a powerful villain from destroying the world? ''[[Anime/YuGiOhBondsBeyondTime Now where have we heard that one before?]]''
* TheUnchosenOne: Although very little is known about them, the Four Duelists are implied to be normal humans who came together in the timeline where Ray and Zarc were born and went against them after the two transcend into godhood by using their own Dueling skills and the Natural Energy Cards that were made by Leo Akaba.

* AdaptationalVillainy: In the canon anime, Yuya, Yugo, and Yuto were the only three of the four counterparts who rejected Zarc's influence, contrasting Yuri who embraces his inner darkness. Here, due to Zarc being kinder, all of them accepted Zarc's power and agreed to help revive him and Ray.
* DemotedToExtra: {{Downplayed|Trope}}. Yuya is TheProtagonist of the canon series, with each of his counterparts getting their own spotlight in the show. Here, they're the [[{{Deuteragonist}} Deuteragonists]] to their respective Siren Girl.

Yuzu's childhood friend and the son of You Show Duel School's founder. He aspires to become an Entertainment Duelist and bring laughter to people through his duels as his father did before him, at least before Yusho's mysterious disappearance three years ago.\\\
He owns a good-luck charm pendant his father gave him when he was younger, which mysteriously glows during his televised exhibition match against Strong Ishijima. This unlocks the power of an entirely new Summoning method, Pendulum Summoning.\\\
He uses a Performapal Deck, which features animals in costumes that focus on altering the ATK and DEF of monsters; he later starts incorporating the Odd-Eyes archetype. His ace is his Odd-Eyes Pendulum Dragon, one of the four Dimensional Dragons.

* AdaptationPersonalityChange: Since Joey and his friends are in this fanfic, they keep him from becoming too much of a StepfordSmiler.
* AdaptationalEarlyAppearance: His Rune-Eyes Pendulum Dragon shows up much earlier than canon.
* AllTheOtherReindeer: Due to his dad disappearing, nearly every kid his age mocked him. This soon becomes subverted after his Duel against Strong Ishijima.
* HeroicBSOD: PlayedForLaughs. When Yuzu gives him a BigDamnKiss in chapter 9, his brain short circuits as he wonders if he's dreaming at that point.
* TookALevelInBadass: Decides to start training and experimenting with Pendulum monsters sooner than in canon and doesn't take as much time to learn how to set a Pendulum Scale, to the point that he can beat Yuzu -- who just learned Fusion and Xyz summoning -- in a duel.

He utilizes the Predaplants, a legion of DARK Plant-type monsters that can swarm the field, impairs and ensnares opponents with their effects, and sets up ideal conditions for his ace monster, Starving Venom Fusion Dragon.

* TheAce: He's known to be the strongest and smartest student in Duel Academia, and he's capable of defeating three Obelisk Blue students on his own, ''simultaneously''.
* AgentPeacock: A flashy dresser and a dangerous duelist.
* AllegedLookalikes: Although Yuzu first mistakes him for Yuya, she quickly deduced that he isn't the latter.
* AmbiguouslyGay: Yuri tends to dress in a rather flashy outfit, speaks very politely, has flamboyant mannerisms, is a CaringGardener (which is traditionally seen as an unmasculine hobby), has a GenderBlenderName[[note]]In Japan, Yuri means "Lily" and it's typically a feminine name.[[/note]] (to which Ray affectionately calls him "Lily"), and is described to have "pretty" eyes. Furthermore, there're some hints of ArmouredClosetGay as according to him, he will sooner teach someone a lesson if they so much as tease him for being feminine. Additionally, he's the only Dragon Boy whose close relationship with his respective Siren Girl being [[PlatonicLifePartners platonic]], rather than romantic.
* BadassCape: A short red one resembling Yuya's coat.
* BadassLongCoat: He wears also a coat since his cape isn't long enough.
* BecauseYouWereNiceToMe:
** The reason why he's so loyal to Leo Akaba is due to the latter acknowledging him as everyone else is too afraid to interact with him. This loyalty later goes away when learning of what he truly was to The Professor from Zarc.
** Ray's familial kindness and love for Yuri is what made him turn to help her and Zarc to revive in the first place.
* BewareTheSillyOnes: Even his basic speaking is theatrical and rather silly. Make no mistake, he's just as capable of switching to sadistic and deadly serious.
* BloodKnight: He's always up for a good duel, especially if it means he could test his strength against others with his ace monster.
* CardCarryingVillain: He's much more bloodthirsty and sadistic compare to his counterparts and is more willing to embrace this status.
* CurbStompBattle:
** He does this to Yuzu in the very first chapter. He used a Fusion Spell Card to fuse two of her ''own'' monsters to Fusion Summon a monster of his own, and would have defeated her if it weren't for Ray taking control to [[InvertedTrope invert]] this on '''him'''.
** He does this to three Obelisk Blue students off-screen in chapter 10.
* DarkIsEvil: His Predaplants and Starving Venom Fusion Dragon are all DARK Attribute, and is the only one of his other counterparts to be a CardCarryingVillain to them potentially becoming an AntiVillain.
* DefectorFromDecadence: He defects from Leo and Academia to help Ray and Zarc to revive them.
* DesperatelyCravesAffection: It's even in his ace monster's name. Despite his prideful nature and his seeming distaste for affection, Yuri craves for it deep down. It's what led to him defecting from Leo and Duel Academia when feeling the affection given to him by Ray for the first time.
* EvenEvilHasStandards: Is utterly disgusted by The Professor's plans to control Ray and her counterparts via parasites.
* TheEvilPrince: Due to being a reincarnation of a demonic draconic god-king, Yuri is this.
* OurDragonsAreDifferent: Starving Venom Fusion Dragon is a Dragon-Type monster. It's a kind of humanoid dragon that has a snake-like appearance and plant-like characteristics.
* PlatonicLifePartners: With Serena.
* PowerCopying: Starving Venom can not only gain the total ATK of a Level 5 or higher monster the opponent controls but also copy the name and effects as well.
* PurpleIsPowerful: His hair color, eye color, uniform, and ace monster is all purple in color, and he's acknowledged as one of the strongest Duelists in Duel Academia along with everyone else fearing him as TheDreaded.
* RelationshipUpgrade: A [[PlatonicLifePartners platonic]] example with Serena.
* SmugSmiler: This is usually his default expression, and not unjustified due to his strength as a Duelist. Any time he stops doing that is usually out of annoyance or genuine anger.
* TookALevelInKindness: Somewhat... but he becomes much kinder in his interactions with Ray and Serena.
* {{Troll}}: He ''loves'' to do this. Zarc even warns Yuto about this aspect of him just to give him the heads-up before heading to the Standard Dimension with Ruri and Shun.
* UndyingLoyalty:
** He had this for Leo Akaba, [[SubvertedTrope at first]] since the man was the only one who acknowledged him whereas everyone else feared him. That being said, he would've later grown out of this anyway due to Zarc's influence.
** He later gains this for Ray and her counterparts, along with Zarc and his counterparts as well.

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/91d70b2b0e5347aa987a95ad4470ca8c.jpg]]

One of the survivors of the invasion on the Xyz Dimension, as well as a member of Resistance. He is Yuya's Xyz Dimensional Counterpart.\\\
He uses a Phantom Knights deck that focuses on summoning Xyz Monsters, including his Dark Rebellion Xyz Dragon, and makes use of Spell and Trap Cards that can be activated from the graveyard.

* BroodingBoyGentleGirl: The stoic and brooding boy to Ruri's compassionate and gentle girl. However, this becomes averted later on with the two becoming gender-inverted examples for a while before losing this dynamic entirely in chapter 13.
* DarkIsNotEvil: Played With. His ace monster and deck are all DARK Attribute monsters, his own appearance has a dark motif, and as a reincarnation/fragment of Zarc, is associated with darkness. However, Yuto is very much a NiceGuy, and could potentially be an AntiVillain at best.
* DoesThisRemindYouOfAnything: Whenever he and Ruri confide with each other in private, their intimate moments can be seen as a '''PG-13''' SexForSolace.
---> Ruri sat up straighter and ran her hand through Yuto's hair and down his cheek, before pressing their foreheads together. "We're all in constant anxiety and fear, smiles are few and fleeting, so any happiness, any small comfort that we can take from each other... it's alright to ask," she whispered, giving Yuto's lips another kiss. Ruri broke the kiss slowly but Yuto pulled her in for another, the kiss became heated and Yuto's hand threaded through Ruri's hair, while the other one was placed between her shoulder blades. Yuto's lips kissed down Ruri's jaw and down her neck as she clung to him, placing her palm over the back of his neck and the other grabbed his shirt. After a while Ruri sat on Yuto's lap, as she buried her head in his neck, Yuto ran his hand through her hair, taking comfort in each others' arms, breathing each other in, so familiar and comforting, yet making the fear grow, the fear to lose all of this, the little happiness between them, the small sweet comfort, making them fight for a new day.
* DraconicHumanoid: In his dream, he's described to have draconic features that are similar to his ace monster.
* FantasticRacism: Despite his kindness, he hates Fusion and those who use it, specifically Academia for their use of the Extra Deck Summoning mechanic to invade Heartland. However, this starts to become downplayed in his meeting with Zarc upon learning the AwfulTruth, his other counterparts (especially Yuri), and Ruri's willingness to learn Fusion if it means it'll help the Resistance in the Interdimensional War.
* LoveAtFirstSight: He had this upon meeting Ruri for the first time as Shun introduces her to him.
* PowerLossDepression: {{Inverted|Trope}}. When he finally accepts Zarc's power, he becomes much more lively than his usual stoic demeanor.
* PerpetualFrowner: He rarely smiles after the invasion of Heartland.
* TheSacredDarkness: Ruri describes him as "the night sky", and his Phantom Knight deck and ace monster are more reminiscent of this rather than the stereotypical DarkIsEvil.
* TookALevelInCheerfulness: As he accepted Zarc's power, Yuto becomes much more lively and hopeful, and is mentioned to be more open with his romantic relationship with Ruri.
* WhenHeSmiles: Whenever he does smile, it shows the rare times he had peace since the invasion started.

Rin's childhood friend who hails from the Synchro Dimension and grew up with Rin as a part of the "Commons" in the slums of Neo Domino City.\\\
He uses a deck with Speedroids, Wind-Machine Type Monsters that resemble toys or are references to games, primarily those centering on dice. Yugo also relies on luck as a powerful factor in his duel style and all his monsters lead up to supporting his ace monster, Clear Wing Synchro Dragon.

* AmazonChaser: If there is one thing we know for sure is that Rin is no meek girl, in fact, she would easily dropkick and punch anyone who annoys her, her anger is terrifying and Yugo absolutely is head over heels in love with her and admires that power, in fact, it turns him on when he sees Rin demonstrating how strong she is, physically, mentally and mystically.
* BigDamnHeroes: Arrives just as Professor Frank as Rin in his clutches, giving her the mental strength to kick him out.
* BiteOfAffection: As a dragon guided by his instinct at that moment, Yugo had the great urge to bite Rin and claim her as his, to show his love and protection of her as well as possessiveness, in his mind Rin becoming his treasure to hoard.
* CasualKink: Implied to have this as he really isn't bothered by Rin's constant sexual aggression.
* BlowYouAway: He's described by Rin as "like the wind", and his ace monster and Speedroid deck is WIND Attribute.
* CutenessProximity: Squees at Akiza's White Rose and Red Rose Dragons, wishing to just take him home and spoil them rotten.
* EatingTheEyeCandy: Does this a ''lot'' whenever Rin dresses provocatively, which is exactly what she aimed for.
* HotBlooded: He tends to listen to his heart rather than use his head at times.
* RelationshipUpgrade: Much to his delight, he gets his feelings returned by Rin and became a couple.

* AttentionWhore: Mana does love the spotlight, in contrast to her twin brother.
* BadassAdorable: She's adorable and she can kick your ass without breaking a sweat.
* BewareTheSillyOnes: Yes she may be a GenkiGirl with a love of Kuribohs and also a hugger...but she's still a strong duelist with a powerful beatdown deck and is SmarterThanTheyLook.
* BlackMagicianGirl: You're looking at the (somewhat) TropeNamer here as not only is her deck the "Magician Girl" archetype, one of her monsters is Dark Magician Girl but it's implied that she ''herself'' has magical abilities.
* BloodKnight: She loves a good duel and has gotten bored with the people she fights. That is, until her loss to Serena and even then she's so happy to find a challenge.

* GracefulLoser: She takes her loss against Serena with stride, as the latter was the first Duelist who really challenges her.
* IdenticalStranger: Her Dark Magician Girl and Apprentice Illusion Magician look exactly like her which many people lampshade.

* [[AbusiveParent Abusive Dad]]: His own father is implied to be this, just like his canon counterpart.
* AdaptationalNiceGuy: In the original manga, he started off as TheBully to Yugi before later becoming his close friend when the latter sticks up for him and Tristan against [[StarterVillain Ushio]]. Here, Joey was already a BullyHunter in his backstory, and his first meeting with Yuya involves protecting the latter.
* BigBrotherMentor: To Yuya, helping him move on from seeing his father just vanish one day.
* BigDamnHeroes: He saves Yuya in their first meeting from bullies who want to harm him due to Yusho's disappearance.
* CompositeCharacter: He shares Gongenzaka's status of being Yuya's protector during the three years of stigma from Yusho's disappearance, along with being something of an older sibling to the latter like how he was with Yugi in the original manga.
* DarkAndTroubledPast: Joey has this like his canon manga counterpart; separated from his sister due to their parent's divorce, being raised by an abusive, AlcoholicParent, and HadToBeSharp in order to fend for himself on the streets till his first meeting with Yuya.

* CoolUncle: To his nephews and niece, as seen in chapter 4.
* DubNameChange: He's known by his dub name instead of his original Japanese name, ''Pegasus J. Crawford''.
* {{Manchild}}: A given. When he meets with the limo driver he states that the in-flight entertainment bored him...and quickly gets excited when he learns there's a copy of ''Yotsuba'' in the limo.
* RelatedInTheAdaptation: He's a the adopted uncule of Mahad, Atem, and Mana in the fic.
* StealingTheCredit: A rare ''positive'' example.

A prominent duelist and a CEO of Leo Corporation. He has a sour grudge towards his father Leo Akaba for abandoning him and his family and aims to defeat his father and Academia in order to stop his evil ambition.

* AdaptationalHeroism: While Reiji is no less capable of committing as many morally questionable acts to achieve his goals as his canon counterpart, his early AmbiguouslyEvil acts of "acquiring" Yuya's Pendulum cards are AdaptedOut thanks to Pegasus StealingTheCredit for the creation of the Pendulum Summoning mechanic in a contract with Yuya and his mom to prevent the boy from getting accused of cheating in his duel against Strong Ishijima, and receiving financial compensation.
* AdaptationalIntelligence: Reiji's plans for creating the Lancers are more thought-out as he intends to have another group of them bring aid to the Xyz Dimension.
* AgentMulder: Reiji is more open-minded about the supernatural and unknown this time around, believing that some other force is what was responsible for Yuya's Pendulum cards.
* DemotedToExtra: In the canon anime, he was Yuya's main rival and the BigGood of his series. Here, he's one of the supporting characters and doesn't get much screen time when compared to his original version, since the story mainly focuses on Ray, Zarc, the Dragon Boys, and the Siren Girls.

* ThirdWheel: Although he isn't really friends with Yuzu and Yuya, he does felt rather awkward when seeing the two interact with each other in chapter 12.
* YouRemindMeOfX: Chapter 10 has Pegasus note that Reiji reminds him of Kaiba due to him being TheSpock. Humorously, this is fitting since Reiji was also a [[CompositeCharacter Composite]]/ContrastingSequelMainCharacter of Kaiba in canon.
* YoungAndInCharge: He's only 16, but is the current CEO of Leo Corporation.

!!Shun Kurosaki
!!!'''Archetype''': Raidraptor
[[quoteright:270:https://static.tvtropes.org/pmwiki/pub/images/kurosaki_shun_3.jpg]]

Shun Kurosaki, along with Yuto, is one of the survivors of the invasion on the Xyz Dimension, as well as a member of Resistance. Originally a kind, if a somewhat stoic person, the invasion took its toll on his psyche. What makes this worse is learning that the true reasons why his home was destroyed and his younger sister Ruri, being planned as a "sacrifice" along with his best friend Yuto, being intended to get killed off by The Professor. He later joins up with Ray as her "knight" to ensure the safety of his loved ones and to make Academia paid for their transgressions.\\\
Shun uses a Raidraptor deck, which is made for swarming Winged-Beast-Type monsters to Xyz Summon monsters with low base-ATK, but powerful effects. He also has many Spell and Trap Cards that can counter various situations and exploits his Rank Up spells to evolve his Raidraptors into more powerful forms.

* AdaptationalAngstUpgrade: In the anime, Ruri being captured by Yuri causes Shun to really start [[SanitySlippage losing it]], and soon became a HeWhoFightsMonsters AntiHero. When being enlightened by the AwfulTruth of the Dimensional War along with the fact that his sister and best friend are to be sacrificed and killed respectively, his thirst for vengeance and hatred goes past the point of no return.
* AdaptationalNiceGuy: Compare to his canon counterpart, who's already a {{Jerkass}} HeWhoFightsMonsters AntiHero at the start of the story, Shun's relatively "nicer" here due to Ruri never having to be kidnapped by Yuri. Furthermore, his BigBrotherBully and ControlFreak tendencies of his sister are relatively toned down here.
* AdaptationalVillainy: At the beginning of the canon anime, he was already a GoodIsNotNice AntiHero [[JumpingOffTheSlipperySlope skirting onto the edges]] of a NominalHero. Here, he fully becomes an AntiVillain since he's helping [[VillainProtagonist Ray]] to ensure the safety of his sister and best friend.
* AntiVillain: After chapter 13, he falls into this role since, despite helping the revival of Ray and Zarc, his goals firmly lie in protecting his sister and best friend, helping the ones they care about, and rebuilding their home after it was laid waste by the Academia Forces.
* BadassLongcoat: He wears a long blue-purple coat and looks tough with it.
* BigBrotherInstinct:
** Ruri may not have been blood-related, it doesn't stop him from being a very doting brother if a little overprotective. So much as he's willing to make a pact with Ray to revive her and Zarc as long as she ensures that Ruri will be still alive in the end.
** He also extends this to Yuto and included his safety as well in his pact with Ray.
* ChessMotif: The Knight, as he serves as Ray's agent in chapter 13.
* CyberneticsEatYourSoul: Metaphorically; his Raid Raptors monsters resemble robotic avian predators, which symbolizes his desire to protect his sister and PayEvilUntoEvil on his foes. However, his devotion to his sister is what Ray recognizes as a good trait.
* DarkIsNotEvil: Played with. Despite his dark attire and joining up with Ray to revive her and Zarc, Shun cares more about protecting his loved ones and hurting those who try to harm them.
* DeathFromAbove: A recurring motif of his Raid Raptors, with Revolution Falcon burying the Obelisk Forces under a hail of bombs in his nightmare.
* EvenEvilHasStandards: Despite being willing to commit morally unconscious acts in order to protect his sister, best friend, and homeland, Shun is quite disgusted by learning how petty Leo's motives are in order to revive his daughter.
* FantasticRacism: Considering what the Obelisk Forces had done to his home, he hates Fusion Summoning. Although this is rather downplayed thanks to Ray and his sister, focusing his hatred on Academia rather than fusion users in general.
* HeterosexualLifePartners: With Yuto, as the two are best friends from thick to thin.
* KarmicJackpot: A villainous example. His love for Ruri is recognized by Ray, who's very happy that her counterpart had such a loving family member and would anything to protect her and their friends. This leads to him being gifted by both Ray and Zarc with his own powers and gain new cards as well.
* KnightTemplarBigBrother: He will do ''anything'' to make sure that Ruri is alright, and he extends to Yuto to a lesser extent. It's also what causes him to ally himself with Ray and Zarc in the first place.
* MagicKnight: A pretty good duelist in a world where duel monsters can be implemented with real magic and is a skilled hand-to-hand fighter capable of taking down several enemies at once. This is much more apparent with Ray and Zarc empowering him with his new cards.
* LoveMakesYouCrazy: His love for his sister Ruri makes him very erratic in his willingness to protect her, which Ray finds endearing.
* LoveMakesYouEvil: He later joins up with Ray into reviving her and Zarc to protect Ruri.
* NoHoldsBarredBeatdown: It's what he ''intends'' to do to The Professor, as his brief fantasy shows, it involves grabbing the man by the throat and bashing his skull against his own throne repeatedly. [[AdaptationalKarma And unlike canon, it's probably going to happen compared to his almost punch at the man]].
* NotSoStoic: He drops his stoicism whenever Ruri or his allies' lives are at stake.
* PowerLossDepression: {{Inverted|Trope}}. As he gains power by accepting the two cards gifted to him by Ray and Zarc, he becomes much more lively.
* TheStoic: He becomes very cynical and emotionless after Academia invaded his home.
* ThreeAmigos: He has this dynamic with his sister and best friend after the three of them are on the same page in chapter 13. This leads to Sayaka feeling uneasy by how the three "move and spoke with a strange union and synchronicity".
* TookALevelInBadass: In chapter 13, he gains powers like his sister and best friend, and his deck gains two more cards from Ray and Zarc respectively.
* TookALevelInCheerfulness: He became very depressed and stoic after Academia destroyed his home, but after accepting two cards gifted to him by Ray he becomes more lively.
* YouAreWorthHell: "The only truth I know is that Ruri is my sister, my family. Nothing will change that, nothing could make her any less important to me."

!!The Enforcers/Monarchs

Four duelists from the Commons banded together to bring peace between them and the Tops. Jack was originally sent into the Friendship Cup to become King, but after he was influenced by Roget, his fellow Enforcers intervened and placed Yusei as the head, and the four to help heal the divide between the two classes.

* AdaptationalBadass: All of them have some sort of strange power to them: Yusei controls electricity, Jack controls fire and Kalin can manipulate shadows. This is even noted in-universe as Armstrong, Grady and Carly note that there were rumors that they had special abilities.
* AdaptationalSexuality: Compare to their heterosexual canon counterparts, all four of them are in a four-way romantic relationship with each other.
* BigGood: To the entirety of Neo Domino City, as they manage to bring order to the society by abolishing the City's [[SocialDarwinist highly competitive culture]] and [[SpannerInTheWorks threw a huge wrench into Roget's plans]].
* DarkIsNotEvil: They either have dark-looking monsters or appearances, and they also have edgy-sounding nicknames, but they're all on the side of good.
* TheDreaded: ''All of them'' are this to most of Neo-Domino. To give an example, seeing Kalin enter Bootleg -- to get Yanagi away from Armstrong -- has an ''everyone in the bar'' run away in terror and for Grady and Carly to realize they're ''fucked''.
* DubNameChange: WordOfGod kept their dub name for the group instead of the original Japanese one (Team Satisfaction), as she states that the Japanese name sounded stupid.
* HeroOfAnotherStory: Their story of how they manage to foil Roget's plans by taking back control of Neo Domino City and abolishes the City's highly competitive culture, is a tale worth telling.
* MythologyGag: In their backstory, they created a safe haven known as "Satisfaction Town", referencing the Crashtown arc.
* {{Polyamory}}: All of them are a foursome of wholesome satisfaction.
* RedBaron: All of them have badass titles: Kallen is "The Shinigami", Jack is "Hell's Harbinger", Yusei is "Stardust Rider"/"King of Neo Domino" and Crow later gets "Black Omen". Crow even lampshades the fact that everyone else got cool names before him. Collectively, they're called the "Lords/Monarchs of Neo Domino".
* StraightGay: None of them display any stereotypical behaviors of homosexuals, as their personalities are relatively the same as their canon counterparts.

[[folder:Yusei Fudo]]
!!Yusei Fudo

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/yusei_fudo_2.png]]
The leader of the Enforcers, current champion of the Friendship Cup and King of Neo Domino.

* InSeriesNickname: He's affectionally called "King" by his fellow Enforcers.
* MustHaveCaffeine: Inverted. Yusei is '''not''' allowed to have caffeine as it makes him even ''more'' of a {{workaholic}}. The last time this happened, it took Jack, Crow, and Kalin to fuck him to wear him down. The reader sees what happens first hand after Randsborgh accidentally leaves a cup out for Yusei. It's apparently so bad that Jack won't even risk giving Yusei an ''iced tea''.
* OnceDoneNeverForgotten: The "Yusei with caffeine" moment with even Yusei complaining it was just one time.
* ProperlyParanoid: Was worried about the trouble Yanagi could get into when his fellow Enforcers reassured him the old man would be fine. Unfortunately none of them counted on Armstrong...
* ShockAndAwe: Has electrical abilities although they haven't been on display yet.
* TranquilFury: When significantly pissed off, he's capable of making ''Jack Atlas'' fear for his life.
* {{Workaholic}}: Yusei will work himself to death if it means making sure others don't have to suffer. It gets to the point that ''Jack'' has to pull him away and make him get some sleep. This is also very common as the other Enforcers have had to pull him away from work, whether it's papers, laptop or just dragging him from tuning up their D-Wheels.

[[folder:Jack Atlas]]
!!Jack Atlas

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/jack_atlas.png]]
Former king of the Friendship Cup and a member of the Enforcers.

* AdaptationalPersonalityChange: He's more humble than he was in canon. Justified in this case as he has his Enforcers to help keep his ego in check.
* GoodWearsWhite: He wears a white jacket and he's one of the Enforcers.
* LethalChef: Cannot cook to save his life. The idea of him making something for Yusei to eat elicits an AnythingButThat reaction from the latter.
* OnlySaneMan: Acts like this when Yusei works himself too much, having to drag him away to get some rest.
* OOCIsSeriousBusiness: It's noted that whenever Jack calls Yusei "King" that it's in a much more affectionate tone than when Kalin or Crow says it.
* PlayingWithFire: Implied to have fire abilities with security guards once having to put out fires that they had no idea where they came from.
* PuppetKing: He was this to Roget and the City Council in his backstory until Yusei manages to defeat him.
* RunningGag: Always likes to bring up Lady Fate to the point that Yusei states that Lady Fate hates him. The author notes lampshade this by stating that no, Lady Fate doesn't hate him; she just likes screwing around with him.
* TrademarkFavoriteFood: Still loves his instant ramen and coffee.

!!!'''Archetype''': Blackwing

A member of the Enforcers.

* InsultBackfire: When Armstrong says that he can't tell why Yanagi is needed, Armstrong states that it would go over his [Crow] "boyfriend's little head". Crow retorts that, aside from Jack, Armstrong has to be more specific since he has ''three'' boyfriends.
* OnlySaneMan: Compared to his fellow Enforcers, he's the most level-headed of the group, even lampshading why he doesn't get some badass title for his own.
* ThisIsGonnaSuck: After the wild goose chase against Armstrong and Yanagi and seeing news crew asking what happens, Crow realizes that ''Yusei'' has just seen all of this and is going to blow a gasket.

!!The Crimson Dragon Crusaders

-->''"This is a new chapter in the history of the Randsborg name for we [Randsborg, Grady, Armstrong, Yanagi and Carly] are now a mighty group who are off to solve the mysteries of the Crimson Dragon. We have now become...the Crimson Dragon Crusaders!”''

Five duelists from the Synchro Dimension came together after seeing Rin dueling Professor Frank and Akiza's Crimson Dragon mark on her arm, diving into the mysteries involving their dimension.

[[folder:In General]]
* AscendedExtra: All five of them were secondary characters who had one duel throughout the entire series (barring Carly who had three). Grady gets this the most since he had little to no personality traits at all (due to being brainwashed at the time).
* FiveManBand:
** TheLeader: Gill Randsborg
** TheLancer: Dick "Grady" Pitt
** TheBigGuy: Mr. Armstrong
** TheSmartGuy: Tenzin Yanagi
** TheChick: Carly Nagisa
* HeroOfAnotherStory: Of the Synchro Dimension side of the fic, one where it involves the lore of the Crimson Dragon being unrelated to Ray and Zarc's revival, uncovering secrets of the Arcadia Movement, and subsequently learning that they're just one part of a bigger puzzle.
* LastNameBasis: Randsborg, Armstrong, and Yanagi are usually addressed this way.
* TheQuest: As Randsborg notes, their quest is to uncover the secrets of the Crimson Dragon, Zarc, and how Rin and Yugo are connected, and why the Arcadia Movement is so interested in them.
* RagtagBunchOfMisfits: They consist of a knight, an archaeologist, a former member of Security, a street duelist with a fondness of milk, and a [[spoiler:crossdressing]] reporter. Armstrong even lampshades that they're "a little ol' Breakfast Club".
* TheUnchosenOne: Despite their group name, none of them are chosen by the Crimson Dragon. Instead, they're just a group made up of individuals who grew curious about the world around them after witnessing the duel between Rin and Professor Frank.

[[folder:Gill Randsborg]]
!!Gill Randsborg
!!!'''Archetype''': Infernoble
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/jilldelancebeaux.png]]

A duelist who hails from a legendary family of knights. He is the first to bring up the legend of Zarc and the Crimson Dragon to the Crusaders.

* AdaptationalBadass: He used LV monsters called Masked Knights in his only duel while the narration states he uses Infernoble this time around.
* AdaptationalNiceGuy: Was an utter buffoon and believed that Akiza was a real witch in the anime, losing to her in a humiliating fashion. In the fanfic, he acts like the TeamDad for the Crimson Dragon Crusaders.
* AdaptationPersonalityChange: He was WrongGenreSavvy against Akiza in the anime, but here he knows well enough ''not'' to start BullyingADragon against her.
* HairOfGoldHeartOfGold: Golden hair and is a gentleman.
* HeroOfAnotherStory: His family has knowledge not only of Zarc, but also of the Earthbound Immortals and Crimson Dragon. What else have they been hiding?
* KnightInShiningArmor: Wears golden armor and is a chivalrous character through and through. Fittingly, he uses the Infernoble archetype.
* LargeHam: As befitting a knight, he likes to go on flowery tangents.
* NiceJobBreakingItHero: PlayedForLaughs. After he and Yanagi are allowed to bunk with the Enforcers to learn more about their powers, he left a mug of coffee for Yusei...not aware that Yusei ''must not have caffeine'' and has to see his fellow Enforcers dogpile Yusei before he works himself to death.
* TheNicknamer: Gives each of his fellow Crusaders different titles, "Valiant Grady", "She of Fair Eyes", etc.
* PlayingWithFire: He is said to have used Infernoble monsters, which are FIRE type.
* StrokeTheBeard: Does this as a {{Character Tic|s}} when in deep thought (even though, as the image shows, he doesn't have one).
* YeOldeButcheredEnglish: Speaks in this as part of being a knight.

[[folder:Dick Pitt (Grady)]]
!!Dick Pitt (Grady)
%%!!!'''Archetype''': ???
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/dick_pitt.jpg]]

A street duelist with a level head and a fondness for milk. He's the reconnaissance man who spies on Rin and Yugo about their powers.

* AdaptationalPersonalityChange: Had little to no personality in the anime and his ''only'' personality came from being a brainwashed goon for Yusei to duel. Here, he's the level-headed member and he's known to be concerned for whatever Carly is getting into and will protect her if she gets into trouble.
* AwesomeByAnalysis: Knew that Xavier Maxa was [[spoiler:Carly in disguise]] by picking up on his habits: stating that being near Armstrong was like living in the Pits (Carly's boss was Mr. Pitt) and bringing up Blue Eyes Mountain Coffees (an expensive brand that Carly knew Jack liked in the anime)
* CrazyPrepared: By the time Rin vs Akiza happens, he made it a habit to carry a parka and coffee since he knows that Rin's ice powers are not to be trifled with.
* CurbStompBattle: He and Carly are on the receiving end of one against Kallen.
* DarkIsNotEvil: Wears black and red and has black hair, but he's level-headed and has no malicious bone in his body.
* EstablishingCharacterMoment: Comes in to save Xavier Maxa from getting a beatdown from Armstrong to showcase that he's a mediator. [[spoiler:This becomes much more meaningful when the reader learns that he knows that Xavier is actually Carly in disguise.]]
* GuileHero: Goads Commander Koda to spill the beans about Akiza by spinning a lie about how Rin could come and freeze his ass off since Rin and Akiza started to become best friends.
* HiddenDepths: He trained under "Enjoy" Chojiro in diffusing fights according to the narration.
* InSeriesNickname: Insists on being called "Grady" instead of his birth name.
* LikeBrotherAndSister: His relationship with Carly in a nutshell as he wants to make sure she doesn't go over her head in regards to her investigations into Arcadia.
* MakingASplash: All that's known about his deck so far is that it's Water based.
* OffscreenMomentOfAwesome: He and Carly apparently fought off Arcadia Movement goons during Rin and Akiza's duel in the Friendship Cup.
* OnlySaneMan: Compared to the knight, the eccentric archaeologist, the grumpy Security guard, and the crossdressing reporter, he's considered to be the normal one. Armstrong even calls him "a level head".
* TakeMeInstead: Decides to take whatever punishment Kalin wants to inflict on him and Carly when Kalin accidentally touches Carly's chest -- as she was disguised as Xavier at the time -- but Kalin decides not to as they weren't his target.
* TrademarkFavoriteFood: He loves drinking milk and states that it won't make you crash or jittery like coffee.
* YouCalledMeXItMustBeSerious: Xavier calling Grady by his real name causes him to step back in fear. [[spoiler:Especially since Grady knows that it's Carly saying that to him.]]

[[folder:Mr. Armstrong]]

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/mrarmstrong.png]]

A former member of Security who, despite not really interested in the magic and nonsense, decides to tag along since he's got nothing better to do.

* ActuallyPrettyFunny: Upon seeing that Xavier had a Fortune Lady deck, he cackles at how he lost to a Fabled deck seeing as he would've had his ass handed if Xavier used the former.
* AdaptationalNiceGuy: Was a HateSink in the anime, to the point that ''Goodwin'' was disgusted by him. Here he's a bit of a grump and would rather ''not'' get involved with the chaos of the Synchro Dimension, but joins in when things start to get too deep. And his antagonism with Yanagi in the story is more on poor communication than him being a jerk.
* AdaptationalPersonalityChange: Instead of a huge jerkwad, he's more of [[JerkWithAHeartOfAgold a grump but not 100% a dick.]]
* CharacterTics: Blowing nose hairs out in public.
* DeadpanSnarker: Has very snarky remarks to all of the magic and mysticism that the group faces.
* DebtDetester: Only helping out with the crazy investigations because he hates giving out favors.
* DumbassHasAPoint: During Rin and Professor Frank's duel, he questions what's so important about Rin that the Professor is trying to hypnotize her. In fact, it's this question that spurs the Crimson Dragon Crusaders to do some investigating on their own.
* EveryoneHasStandards: He's an unpleasant jerk to be around but he has low esteem for [[BigBad Jean-Michel Roget]] and thinks that [[SmugSnake Professor Frank]] brainwashing Rin (a ''14-year-old girl'') is low. In fact, he personally was going to stop the duel himself if it continued. He also showed concern when Akiza's arm started to glow with her Crimson Dragon Mark.
* HoistByHisOwnPetard: The details of his duel against Xavier are vague but all we know is that his milling strategy ended up backfiring on him when Xavier's Fabled Leviathan was destroyed and he was able to retrieve three Fabled monsters from the graveyard (one of them being The Fabled Catsith).
* MisterExposition: He knows the most about Rin and Yugo and later reveals that he has heard rumors about [[spoiler:Security having Polymerization and Fusion Monsters]].
* NiceJobBreakingItHero: Nearly gets Grady and Carly into loads of trouble when he antagonizes Yanagi ''without'' explaining why he was chasing after the old man. Not helping that Crow and Kallen were ''also'' chasing him down since they knew each other in the past. He realizes his mistake when he learns how Crow has a Crimson Dragon mark.
* PoorCommunicationKills: Chases after Yanagi ''without'' explaining that he needs Yanagi's info about the Crimson Dragon nearly got him, Grady and Carly into loads of trouble when Kalin and Crow arrived and ''also'' needing Yanagi's help)
* SoreLoser: Subverted; he got mad when he lost to Xavier, but kept his cool and leave the arena without inciting a brawl.

* BigEater: He had three bowls of Oden before he was going to see Yusei. Then Armstrong arrived.
* CoolOldGuy: He's a jovial fellow, the eldest member of the Crusaders and is the least serious member of the five.
* HeroOfAnotherStory: Whatever he's seen throughout his travels must be very interesting.
* IntergenerationalFriendship: Is good friends with Crow and Kalin, having met them when they were imprisioned in the Facility.
* TrademarkFavoriteFood: Oden. Armstrong was able to track him down because of this. Sure enough, Yanagi had finished about three bowls before Armstrong arrived.

A freelance reporter who is investigating the Arcadia Movement to find the whereabouts of her friend, Misty Lola's, little brother.

She also has a disguise as "Xavier Maxa", see tropes below for him.
-----
* AdaptationalBadass: Only had one victory -- back when she was a Dark Signer -- but she was able to beat Armstrong ''and'' destroyed Akiza's Black Rose Dragons '''twice''' due to the effects of her cards.
* AdaptationalPersonalityChange: Much more assertive as she was able to get her former boss fired and also snarkier than in canon.
* AdaptationRelationshipOverhaul: Does not have a crush on Jack Atlas in this setting -- as he's in a polyamorous relationship with the other Enforcers -- but has a sibling-like relationship with Grady.
* BerserkButton: Professor Frank using her catchphrase while he's brainwashing Rin causes her to snap. She also does not like casual sexism as she tells Randsborg, when she's disguised as Xavier, to stop thinking of women as if they're from the Middle ages.

* LightEmUp: Used the Fabled archetype which are all LIGHT monsters.
* LightIsNotGood: Zigzagged; the Fabled monsters are a bunch of a-holes, as Xavier explains to Randsborgh, but Xavier/Carly is a good-hearted person.
* OffscreenMomentOfAwesome: Defeated Armstrong in the underground tournament due to using Fabled Leviathan and The Fabled Caitsith.
* SamusIsAGirl: Xavier is actually Carly in disguise.
* ShoutOut: He's named after a character from Green Phantom Queen's own story ''Fanfic/BetweenMyBrotherAndMeMorsOmnibus''.
* ThisIsGonnaSuck: His reaction to fighting Akiza is knowing that he's gonna die.
* WalkingSpoiler: Xavier is thought to be an OC character in the story and just there to show how dangerous Akiza is; he's anything ''but'' some one-episode character.
* WigDressAccent: To disguise herself as Xavier, Carly just wears a long white blouse, a leather jacket, jeans, a short wig, and shades.

* CompositeCharacter: Is basically her anime self but she uses the cards that her manga counterpart had (White Rose Cloister and Black Rose Moonlight Dragon)
* TheDreaded: She's known as the "Black Rose Witch", and is a very powerful Duelist who strikes fear into many people.
* InseriesNickname: Usually goes by Akiza, but Rin calls her "Aki" for short.

* FauxAffablyEvil: Looks and acts like a calm professor...really is a sadist who doesn't mind brainwashing a little girl.

!Fusion Dimension
!!Academia

The Fusion Dimension's Duel Academia, who make it their life's mission of attacking other dimensions and sealing their victims into cards. A majority of people from this dimension are quite sadistic, treating their heinous actions as a "hunting game" and laughing about the destruction that they cause.

[[folder:Leo Akaba]]
!!Professor Leo Akaba/The Professor
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/leo_akaba.png]]

Ray's father, who three years ago went to the Fusion Dimension, where he became the Professor, the head of Academia. He is the instigator of the interdimensional war with the intent to conquer all dimensions and unite them under his command.\\\
The Professor originally hailed from the Original Dimension where his technology gave Duel Monsters the ability to interact with reality itself, as well as invoking in them actual feelings. This backfired spectacularly when he inadvertently helped create the "Demonic Duelist" known as Zarc and the fusion of all his dragons... with his daughter Ray joining him as they declared war on humanity.\\\
Thus the entire reason for starting the war in the first place is his ill-guided attempt to "unite" the dimensions once again and revive his daughter Ray, who he believes Zarc "corrupted" into joining him.
----
* AdaptationalJerkass: Compare to the canon series, this version of Leo was quite neglectful of Ray and is implied to be very controlling of her prior to the Original Dimension's destruction, adding another layer to his already questionable sanity and delusion.
* ArchnemesisDad: To both Ray and Reiji.
* BadassBookworm: He's not only a multi-disciplinary scientist but is capable of running a military school as its headmaster.
* BaldOfEvil: He's completely bald in the current time, and is willing to launch an unprovoked war against the other Dimensions to resurrect a child who simply doesn't exist beyond his own delusion.
* ControlFreak: He was this to his daughter in the Original Dimension, and it still sticks up to this day.
* TheCorrupter: Ever since he established control in the Fusion Dimension, he indoctrinate most of Duel Academia's students into genocidal soldiers and encouraged Yuri into the monster he's well known to be at the beginning of the story. This makes his grudge against Zarc for supposedly "brainwashing" his daughter all the more ironic.
* DramaticIrony: The entire plot of the story can all be traced back to his own ''parental flaws'', and is only going to be causing more problems for him in the long term.
* EvenEvilHasLovedOnes: For all of his flaws, all the things he does is to attempt to be reunited with his daughter, Ray, after her soul was split across the four dimensions. This is deconstructed, however, as it not only causes him to commit heinous actions to achieve his goal of reviving her, it also showcases his ParentalObliviousness to Ray.
* {{Hypocrite}}: He has a personal grudge against Zarc for not only destroying the Original Dimension but is also fully convinced that the latter brainwashed his beloved daughter into becoming a villain. Yet, he's completely oblivious to the fact of the pain he's causing by waging an unprovoked interdimensional war, spent years [[TheCorrupter indoctrinating]] {{child soldier}}s into doing his dirty work, ''and'' is willing to have the Doktor used the Fusion Parasites to brainwash his daughter's four reincarnation/fragments.
* {{Irony}}:
** His neglectfulness and controlling nature for Ray, [[YoureNotMyFather who wants nothing to do with him anymore]], and ParentalAbandonment of Reiji, has led to both children plotting against him. Which is rightfully lampshaded by Serena in her personal chapter.
** If you have already read the hypocrisy of his actions above, then you can already tell that not only does the actions he took makes him NotSoDifferent from Zarc, but also NotSoSimilar as Leo is far ''worse'' for his delusional and controlling behavior.
* NonActionBigBad: He currently sits at his throne in the Fusion Dimension while sending out Duel Soldiers to invade the dimensions.
* NotSoSimilar: To Shun Kurosaki in the canon anime's English Dub. From there, Shun realizes that both of them committed morally unconscious acts in order to get back a family member that they loved and lost; Shun for Ruri and Leo for Ray. Furthermore, Leo's ControlFreak and OverprotectiveDad tendencies here are quite reminiscent of Shun's own controlling and protective behavior for Ruri in the anime. However, that's where the similarity ''ends'' here in the fic, as, unlike Leo's obliviousness and [[LovingAShadow shadow love]], Shun ''genuinely'' loves Ruri and is capable of recognizing her for her own character and choices and doesn't prevent her from having a romantic relationship with Yuto before a disastrous event, who is his best friend and the one other person in his life who he explicitly trusts. [[FridgeBrilliance In fact, this crucial difference is possibly another reason why Ray recruited Shun as her knight and agent besides his devotion to his sister.]]
* ObliviouslyEvil: He completely disregards the pain and despair he causes for others throughout the Four Dimensions simply due to his delusional belief that everyone aside from himself, Ray, and Zarc is not ''real'' as they only exist as "mistakes" due to the fracturing of the Original Dimension.
* OmnidisciplinaryScientist: If you haven't read the long list from the canon series' page, then you'll know that'll it be too long to list here.
* OverprotectiveDad: According to WordOfGod, he never approved of his daughter's friendship with Zarc, but couldn't keep them apart as he was too busy with his work to notice their secret hangouts and relationship. This is fully {{deconstructed|Trope}} as, unlike the usual examples, it's another sign of his ControlFreak tendencies.
* ParentalNeglect: {{Deconstructed}}. Leo and his wife were never really around for his daughter, Ray, and if so, they gave her very little personal freedom. This is what leads to Ray leaning onto Zarc for support, and vice versa as BirdsOfAFeather, and ended up with her joining Zarc into laying waste upon humanity for their bloodlust.
* ParentalObliviousness: Leo Akaba only cares about resurrecting his "perfect daughter" while disregarding her four counterparts as merely "sacrifices", and believing that Ray was ''brainwashed'' by Zarc into joining him in the first place. To put it simply, Ray is [[EvenEvilHasStandards disgusted]] by this delusion and had [[YoureNotMyFather renounced]] Leo as her father ''long ago''.
* UnwittingInstigatorOfDoom:
** His research to enhance Real Solid Vision, which allowed Zarc and Ray to summon and then fuse with their monsters, leading to the end of the original world.
** On that note, his ParentalNeglect of Ray is part of the reason she even joined Zarc in the first place.
** Sending Yuri to kidnap Ray's incarnations, bringing the girls together which jump-starts the plot.
** He started the Dimensional War because of his unthinking selfishness, driving Yuto, Ruri, and Shun to the arms of Zarc and Ray very easily.

* AdaptationExplanationExtrication: None of their duels are written onscreen in the fic, as WordOfGod stated that she doesn't know how to write a duel in the Battle Royal Format that was in the anime since it doesn't have any clear rules, and a duel with that magnitude needs far more set up. However, the writer has made her own rules and will be using them in a future chapter.
* AlwaysMale: So far, the group doesn't seem to have any female members.
* AncientGrome[=/=]ClockPunk: Like many other Duel Soldiers, they use cards such as Ancient Gear Knight and Ancient Gear Hunting Hound.
* BegTheDog: They won't hesitate to beg their "prey" for their lives in case they actually lose a duel. If anything, it only makes their own defeat and death more cathartic InUniverse.
* BloodKnight: {{Subverted|Trope}}. They'll revel in a good fight against the "Xyz Scum" if only to make their hunting games more enjoyable once they'll defeat and card them as their fallen prey begs for mercy. But when things go south and they ''actually'' lose the duel, they won't hesitate to run away in fear or ''beg their'' '''''prey''''' ''for mercy''.
* BullyingADragon: As seen in their off-screen 3-to-1 duels against Ruri and Yuri respectively. It doesn't end well for them either way.
* ColorCodedForYOurConvenience: Their masks have gems of different colors set in them, which is generally the only way to tell them apart. Doesn't make too much of a difference because they're all basically interchangeable, to begin with, but it does make their duels easier to follow.
* {{Combat Pragmatist}}s: They duel in Battle Royal Mode rather than in regular 1-on-1 duel. Since the Battle Royals don't have specific rules, they attack their opponents before those even get their first turn.
* CyberCyclops: Chaos Ancient Gear Giant.
* DirtyCoward: What most, if not all, of them are deep down. They're fine with attacking in numbers and acting all smug while in a position of being a predator. Yet, when they lose in spite of having those advantages, they'll either run away in fear or beg for mercy.
* EliteMooks: PlayedWith. They are the highest-ranking students of Duel Academia, like the lore of ''GX'', and their invasion of the Xyz Dimension involves them defeating and carding many duelists and civilians alike. However, they're only truly a threat due to their [[ZergRush strength in numbers]], overreliance on the Battle Royal Mode, having the initial advantage of AttackAttackAttack. Once those tactics are no longer valid and they end up losing a duel, they either [[DirtyCoward run away in fear]] or [[AintTooProudToBeg beg for mercy]].
* HumongousMecha: They have a Chaos Ancient Gear Giant to use in their decks.
* {{Jerkass}}: So far, every single one of them.
* {{Mooks}}: All of them wearing the same uniforms, wear almost the same [[FacelessGoons masks]], all share the same personality, and all of them seem to run Antique Gear decks. Unfortunately, they are also EliteMooks.
* RedEyesTakeWarning: The red lenses of their masks lend themselves to this effect.
* {{Sadist}}: They feel pleasure from hurting and carding people.
* SmugSmiler: All the time.
* SmugSuper: They can come off as SmugSnake, but they're technically this since they're actually good Duelists by the standards of their home dimension.
* SpoiledBrat: While Ruri describes all of the Academia Duel Soldiers as this, the Obelisk Force is more guilty of this trope, if one knew of how the Obelisk Blue students from ''GX'' are mostly comprised of {{Jerkass}} rich kids and female students regardless of their initial Duel performances (as the Obelisk Blue Dorm is the only student residential area that has working plumbing for female students).
* WeaponOfChoice: Every monster they use is either an Ancient Gear Hunting Hound or one of its Fusion forms.
* ZergRush: Their preferred tactic to duel is by using the Battle Royal Format to overwhelm their opponents, whether it'll be to card their prey in the Xyz Dimension or to bully lesser students in Academia. {{Deconstructed|Trope}} as this also falls into CripplingOverspecialization, as they can get blindsided by an opponent who uses effects that could take down multiple monsters in a single turn.

!Original Dimension
!!The Four Duelists
A group of four Duelists from "different times" who battle against the recently transcendent Gods, Ray and Zarc. It led to the fracturing of the Original Dimension, along with the lives of them being sent throughout the Four Dimensions.

[[folder:In General]]
* BigGood: They're the closet thing for the Original Dimension, and possibly of the entire fic by the whole.
* CompositeCharacter: They took Ray's role as the GreaterScopeParagon against a GreaterScopeVillain from the canon anime.
* FourIsDeath: The four of them battling against the godlike Ray and Zarc causes the Original Dimension to split into the Four Dimensions, as well as them being flung through and separated with no memories of their past lives.
* TheGhost: They're repeatedly mentioned from time to time, but haven't made an appearance nor do we learn of their true identities.
* GreaterScopeParagon: They essentially went against two beings who had already become [[PhysicalGod Physical Gods]], and manages to prevent them from destroying the rest of humanity, leading to the fracture of the Original Dimension.
* HeroAntagonist: They were the ones who oppose Ray and Zarc after the two wage war against humanity as gods.
* MinorMajorCharacter: Very little is known about them throughout the story, but Ray and Zarc know ''who'' the four of them are and have shared it amongst their allies. According to WordOfGod, the revelation of their identities will mark a turning point.
* MythologyGag: A group of Duelists who came from different timelines and band together to stop a powerful villain from destroying the world? ''[[Anime/YuGiOhBondsBeyondTime Now where have we heard that one before?]]''
* TheUnchosenOne: Although very little is known about them, the Four Duelists are implied to be normal humans who came together in the timeline where Ray and Zarc were born and went against them after the two transcend into godhood by using their own Dueling skills and the Natural Energy Cards that were made by Leo Akaba.
[[/folder]]

!The Siren Girls

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/bracelet_girls.jpg]]
* ActionGirl: They are all very skilled Duelists, capable of being equal to their respective Dragon Boy, and can kick ass if the situation calls for it.
* AdaptationExpansion: The fic delves more into the individual Siren Girl's lives than in canon.
* AdaptationRelationshipOverhaul: Compared to canon, where only Yuzu and Serena developed a close bond as Rin and Ruri were already BrainwashedAndCrazy before the start of the series, all four of them met in Ray's MentalWorld through TwinTelepathy and later bond with each other to the point of considering one another as a sister.
* AdaptationalAngstUpgrade: When learning the AwfulTruth of the Dimensional War and what Leo Akaba plans to do with them, none of the Siren Girls ''took the news well'' '''''at all'''''. What keeps their sanity together was the emotional support from Ray, Zarc, each other, and their friends and family.
* AdaptationalBadass: In the canon anime, the girls were capable Duelists in their own right, but were limited to their native Extra Deck Summonings; Yuzu only knew Tribute Summoning before learning Fusion from Sora, Serena for Fusion, Rin for Synchro, and Ruri for Xyz. And while the latter two do know Fusion Summon, it's only due to them being BrainwashedAndCrazy by Academia, with their respective Fusion Monsters being "relatively mediocre" at best according to WordOfGod. ''Zero Hour'' has each of the Siren Girl learning all known Extra Deck Summoning mechanics, allowing them to become more powerful and skilled as Duelists, and the ability of {{Reality Warper}}s.
* AdaptationalNameChange: Since their original incarnation doesn't use the Natural Energy Cards, they're known as the "Siren Girls" here instead.
* [[AdaptationalNiceGuy Adaptational Nice Girl]]: With the exception of [[NiceGuy Ruri]] and Yuzu (to a certain degree), Serena and Rin are much kinder and cooperative due to their sisterly bonds than in canon.
* AdaptationalSkill: In canon, the Bracelet Girls are only shown to use one or two methods of the Extra Deck Summonings. Here, the Siren Girls learn to use ''all'' known Extra Deck Summoning methods (Fusion, Synchro, Xyz, ''and'' Pendulum).
* AdaptationalSuperpowerChange: Due to their original incarnation using the Natural Energy Cards to stop Zarc in canon, each of the girls is born with the purpose to keep their respective Dragon Boy from becoming one again, with Yuzu's bracelet causing random teleportation whenever a Dragon Boy gets too close to another with the pink-haired girl around, while every other bracelet was completely useless never protecting the girl herself from any harm. Here, since Ray joins Zarc in destroying the Original Dimension by fusing with her Siren monsters, the Siren Girls instead have the powers of a RealityWarper.
* AdaptationalVillainy: In canon, the Bracelet Girls were the BarrierMaiden to Ray's GreaterScopeParagon. Since Ray is one of the [[GreaterScopeVillain Greater-Scope Villains]] here, this would make them an ApocalypseMaiden instead.
* AmazonBrigade: All of them uses decks composed of female monsters.
* AnimeHair: All of them have two strands of different colored hair.
* AscendedExtra: In canon, the Bracelet Girls were important to the plans of [[BigBad Leo Akaba]], thus making them important characters to the series plot-wise; Yuzu is the {{Deuteragonist}}, Serena is a secondary supporting character, and Rin and Ruri were {{Satellite Character}}s who was mentioned early on, but was OutOfFocus before appearing later on in Season 3. Here, the Siren Girls are the central [[TheProtagonist protagonists]] of the fic, and they each get an individual focus in the story.
* BrainwashedAndCrazy: {{Averted|Trope}}. WordOfGod states that they won't be infected by the Fusion Parasite like in canon.
* ClonesArePeopleToo: Well... they're technically four [[LivingMacGuffin Living MacGuffins]] of Ray, but she and Zarc treat them as their own individuals and acts as a supportive older sibling/parental figure to them.
* ConvenientlyAnOrphan: This applies to all of them as the Four Dimensions have only existed for over a decade and being {{living MacGuffin}}s of a godlike being.
* DaddysGirl:
** {{Subverted|Trope}} with Leo, as he only cares about them in order to resurrect his daughter Ray.
** Played straight to Zarc, as Ray tells them that they're his "little princesses".
* FamilyOfChoice: Despite being counterparts of each other in different dimensions, the Siren Girls treat each other as sisters.
* LadyMacbeth: Each of the Siren Girls serves as this to their respective Dragon Boys, as they slowly confide in them to bring out their inner Darkness for Zarc's revival.
* LivingEmotionalCrutch:
** After meeting together with Ray in a shared mindscape, each of the girls became this to each other by providing emotional support to the other.
** All of them are this to their respective Dragon Boys, and vice versa.
* OnlyOneName: While Yuzu and Ruri do have last names, all of the Siren Girls never originally had one due to them being [[LivingMacGuffin Living MacGuffins]] in a [[EarthIsYoung world that only existed since their birth]].
* {{Reincarnation}}: They're this to Ray Akaba of the Original Dimension.
* RelationshipUpgrade: They become much closer to their respective Dragon Boy; Ruri and Yuto become more openly affectionate, Yuzu and Rin started dating Yuya and Yugo respectively, and Serena and Yuri becoming PlatonicLifePartners.
* RotatingProtagonist: Each of them gets the spotlight in the narrative whenever the chapters focus on.
* TookALevelInBadass: All of them were already capable Duelists by the start of the story, but they become more powerful as they gain more upgrades to their playstyle.

[[folder:Yuzu Hiiragi]]
!!Yuzu Hiiragi
!!!'''Archetype''': Melodious
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/hiiragi_yuzu.jpg]]

One of the protagonists of ''Zero Hour'' and Yuya's childhood friend, she is the daughter of You Show Duel School's headmaster. Where Yuya is energetic and upbeat, she is more rational, though rather quick to lose her temper. She has a habit of whacking people, particularly her father and Yuya, with a paper fan whenever she's annoyed with them. She is a "piece" of her original incarnation named Ray, a young woman who joins her beloved, Zarc, into destroying the world.\\\
Yuzu plays a Melodious deck which largely relies on Special Summoning multiple smaller monsters to Tribute Summon her ace, Prodigy Mozart, which Special Summons more Melodious monsters, continuing the chain.

* AdaptationRelationshipOverhaul:
** Yuzu and Sora never developed the mentor-and-mentee relationship as the former learn Fusion from Ray instead. Furthermore, Sora is currently LockedOutOfTheLoop about Yuzu's identity of being the one he's sent to help capture for The Professor.
** Her rivalry with Masumi from canon is AdaptedOut in the fic as confirmed by WordOfGod.
* AdaptationalIntelligence: {{Downplayed|Trope}}. When she first met Yuri in chapter 1, Yuzu could ''immediately'' tell that he wasn't Yuya despite being an IdenticalStranger in contrast to how she spends ''21'' episodes still confused about Yuto, along with a certain degree of SanitySlippage in canon before learning the truth. Although this is justified due to the "circumstances" of their first meeting.
* AwesomenessByAnalysis: As seen in her first meeting with Yuri, she could already tell that he isn't Yuya just by his expressions and the malevolent feeling he gives off.
* BigDamnKiss: She gives one to Yuya in chapter 9, much to the surprise of everyone around them, especially to the shock of her father Shuzo.
* ChildhoodFriendRomance: She knew Yuya when they were kids, and the two of them have feelings for each other before her BigDamnKiss in chapter 9.
* CoolBigSis: She acts this way to the younger students of You Show Duel School.
* DaddysGirl: She and her father Shuzo shares a very close bond.
* FeminineWomenCanCook: She usually cooks for her father at times, and in chapter 10, she once stated that she would cook a big meal for the other girls when they crossover to the Standard Dimension.
* GirlishPigtails: She wears her hair in this style, complete with blue barrettes.
* GirlyBruiser: Both she and her deck are overtly feminine, and she's proven herself to be a capable duelist.
* HappilyAdopted: She is perfectly happy being Shuzo's daughter.
* TheHeart: She acts as this whenever certain conflicts arise with her counterparts in Ray's MentalWorld.
* [[MrExposition Miss Exposition]]: She acts like this in chapter 9, using her newfound knowledge of the Extra Deck Summoning methods from Ray and her counterparts to explain to Yuya and Gongenzaka why she intends to shop for new cards.
* MsFanservice: {{Discussed|Trope}} and ultimately subverted. In chapter 17, she thought about being this like how Rin does with Yugo while mulling over what to wear for her first date with Yuya, only to feel quite scandalized when Ray asks her if she could imagine herself walking around in public wearing a small top and short shorts.
* PinkIsFeminine: She has pink hair, pink in her clothing design, and most of her monsters have pink in their designs, making Yuzu quite feminine among her counterparts, second only to Ruri Kurosaki and tied with her original incarnation, Ray Akaba.
* RelationshipUpgrade: She and Yuya become a couple after his victory against Strong Ishijima.
* StraightManAndWiseGuy: This is her dynamic with Yuya, being the straight guy to his wise guy.
* TookALevelInBadass: As she learns the other Extra Deck Summoning methods from Ray and her counterparts, she grows into a stronger Duelist. A good example is by the time where she gets her first on-screen duel in chapter 11, she's already capable of Fusion ''and'' Xyz Summoning, and manages to whittle down Yuya's LP to 2700.
* {{Tsundere}}: Yuzu is generally kind, but Yuya's messing around annoys her. This goes away as the latter becomes less goofy and the two started dating.

[[folder:Serena]]
!!Serena
!!!'''Archetype''': Lunalight

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/serena_8.jpg]]

Serena hails from the Fusion Dimension and has been held against her will inside Academia for about three years despite being on their side. After learning the AwfulTruth of the true nature of her comrades and how she's nothing more but a sacrifice for The Professor, Serena joins Ray and her other counterparts in their efforts to revive Zarc.\\\
Serena uses a Lunalight deck, which features female, animal-like monsters with a moon theme. Unlike Yuzu's Melodious deck, Serena's deck is very offensive.

* AlmightyJanitor: She wears the alternate Duel Academia's version of the Osiris Red uniform, with Osiris Red being the lowest ranking dorm.
* AmbiguouslyGay: She's far more [[TheLadette tough and unfeminine]] than her other counterparts and would be the first one who'll resort to giving someone an ass-kicking if pissed off. Additionally, she is the only one of the Siren Girls whose close relationship with her respective Dragon Boy is [[PlatonicLifePartners platonic]], rather than romantic, and is shown to be much closer to her counterparts instead.
* BadassAdorable: She's a capable Duelist, and looks very cute as well.
* BigDamnHeroes: Alongside Sora, they both save Yuya from being assaulted by Gen Ankokuji and his flunkies in chapter 11.
* BigWhat: She says this when Ruri angrily accuses her and Academia of being nothing more than heartless monsters who want to destroy everything in her home, which would have almost escalated to a physical altercation between the two if Ray hadn't appeared.
* BloodKnight: She is really combatant happy, refusing to retreat or anything.
* BrokenPedestal: She looks up to Leo Akaba as a father figure, often acts rebellious to prove her worth as a Duel Warrior. She also believes in the cause of Academia, as it would mean to bring honor to oneself as a soldier and thought to bring peace to the other dimensions. However, when she learns the AwfulTruth from Ray and her other three counterparts, it didn't take a week for whatever admiration she had for Leo and the Academia's cause to be dead.
* CryCute: She let out her pent-up frustrations in tears when being comforted by Zarc for the first time, as it was also the first time she felt a form of fatherly affection.
* CuteBruiser: She's quite easy on the eyes, but don't think for a moment that she's fragile like a china doll. She's a capable Duelist, with her Lunalight monsters are basically "'''OTK enablers'''", according to Azure-Witch[==]13, and is a great physical combatant.
* CutenessProximity: Her reaction to Mana's Kuribohs says it all.
-->'''Serena:''' ''(while holding onto a Kuriboh and having sparkling eyes)'' "It's... so... FLUFFY! IT'S LIKE A FLUFFY LITTLE KITTY!"
* DefectorFromDecadence: She does this after seeing the actual methods Academia uses and what Leo intends to do with her.
* DesperatelyLookingForAPurposeInLife: After the results of her BrokenPedestal of Leo and Academia, she spends a brief amount of time wondering where to go from there, and soon resolves herself into helping Ray and Zarc to revive them.
* EasilyForgiven: {{Justified|Trope}}. After learning the AwfulTruth, Yuzu, Rin, and even ''Ruri'' don't hold it against Serena for what Academia had done to the Xyz Dimension so far, knowing that she's completely unaware of their true goals along with her being a pawn for Leo as well.
* EveryoneHasStandards: Even before she defected to Ray and Zarc's side, Serena fully believes in the idea of warrior's honor, as she would never [[NeverHurtAnInnocent someone if they can't defend themselves or has nothing to do with Dueling]]. Furthermore, this also gives her a low tolerance of ZergRush, whether in the Battle Royal Format or in an actual fight and seeing people who rely on it as [[TheBully bullies]] and [[DirtyCoward cowards]].
* FantasticRacism: Like other members of her faction, she looked down on Xyz users. ''Unlike'' other members of her faction, it's because she honestly believed they're evil; when the Fusion forces were attacking Xyz Dimension, Serena was purposely prevented from going by the Professor, and he seems to have misled her as to his actions and intentions. This is fully {{averted|Trope}} after discovering the AwfulTruth through Ray and her counterparts, leading to Serena eagerly wanting to learn the other Extra Deck Summoning methods, including ''Xyz''.
* IJustWantToBeFree: Her true goal in life, and it's one of those reasons she had sided with Ray and her counterparts.
* IncompatibleOrientation: {{Discussed|Trope}} and {{Reconstructed|Trope}}. Serena brings up the fact of whether or not she's capable of bonding with Yuri, as she doesn't really know him like how her other counterparts' bonds with theirs nor if she likes him in a romantic sense (and vice-versa). Ray assures Serena that even if she doesn't love him, he'll be there for her as a [[PlatonicLifePartners close companion]].
* InnocentlyInsensitive: She casually replies to Ruri's shocked exclamation of her being from Academia with a "Yeah, what of it?", completely unaware of the turmoil and trauma that the latter went through since the invasion of Heartland. Justified as Serena was still under the impression of Duel Academia being a benevolent force to bring upon a "Utopia", only to be completely disgusted and horrified of their true motives.
* NeverHurtAnInnocent: She's appalled when learning that innocents; people who didn't duel, children too small to even defend themselves were being hurt and carded in the Xyz invasion.
* NoSocialSkills: She never once left Academia was practically raised there her whole life, making her very socially inept besides dueling. This starts to be subverted as she bonds with Ray and her counterparts, Yuri, Zarc, and her Lunalight monsters.
* OddNameOut: Compare to her other counterparts (while Rin's name is Italian in origin, it's popular in Japan for its consistent meaning), Serena's name is western in origin.
* OutOfCharacterAlert: PlayedForLaughs. She's mainly known to be a NoNonsenseNemesis of a soldier, with ''no'' indication of being "girly" in Duel Academia and can kick anyone's asses if she wanted to, leading Sora to be all the more shocked when he witnesses Serena's CutenessProximity with Mana's Kuribohs.
* PerpetualFrowner: In contrast to Ray and her counterparts, Serena is usually seen with a frown or scowl on her face. This becomes downplayed in her CharacterDevelopment.
* PlatonicLifePartners: With Yuri.
* RelationshipUpgrade: A [[PlatonicLifePartners platonic]] example with Yuri.
* TomboyWithAGirlyStreak: [[DoubleSubversion Double Subverted]]. While her deck is very feminine, the play-style of her deck revolves around attacking as much as possible while preventing her opponent from protecting themselves; fitting given some of her [[BloodKnight tendencies]], so it might just be that she doesn't care for looks as long as what she's using works. She's also the only "Yuzu" counterpart who hasn't shown any form of positive emotion towards her "Yuya" counterpart.[[note]]However, given the fact that Serena is not sadistic and doesn't enjoy destruction as Yuri does, it's unlikely that she will EVER have any towards the guy.[[/note]] However, after she TookALevelInCheerfulness through the emotional support of Ray, her counterparts, Yuri, Zarc, and her own monsters, she's much more open with her feminine side among friends as she absolutely ''coos'' when Mana introduces her to Kuribohs.
* TookALevelInCheerfulness: As she spends time with Ray and her counterparts, Serena becomes much more outgoing than the aloof girl at the beginning of the story.
* TookALevelInKindness: She becomes much kinder through her bonds with Ray and her counterparts, Yuri, Zarc, and her Lunalight monsters. A far cry from how she started in the story.
* WellIntentionedExtremist: She fully believed that what the Professor wants is for the greater good, and even if the Xyz duelists lost, they still had their pride despite losing. After she learns the AwfulTruth, Serena was outright horrified and disgusted, leading to her becoming a DefectorFromDecadence.
* WhenSheSmiles: She's the only Siren Girl who doesn't really smile due to her upbringing, but when she does, it's absolutely adorable.
* WorthyOpponent: She sees Mana as this due to her strength and competitiveness.

[[folder:Ruri Kurosaki]]
!!Ruri Kurosaki
!!!'''Archetype''': Lyrilusc
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/kurosaki_ruri.jpg]]

A girl that comes from the same place Yuto and her brother Shun Kurosaki comes from, Heartland City. After being spied on by Dennis and having her home dimension be nearly destroyed by Academia.\\\
One day during a mission, Ruri was contacted into the mindscape of where she meets Yuzu and her other counterparts. When learning of the AwfulTruth of why her home was destroyed and her true purpose as a sacrifice for The Professor, Ruri became much more harden in her resolve to fight against the Academia Forces and aids Ray into reviving Zarc.\\\
Ruri uses a Lyrilusc deck, a Luscinia-based archetype that utilizes Xyz Summoning.

* ActionSurvivor: As she steels herself to protect those she loves, Ruri becomes one of the Resistance's strongest Duelist and proves just how deadly she can be.
* AdaptationalAngstUpgrade: She gets this harder than her other counterparts. After learning the AwfulTruth of why her home was invaded along with her own role in Leo's plans, Ruri becomes more distant and cynical in personality, no longer adhering to Yusho's philosophy and is only concern with crushing the Obelisk Forces in order to save her friends and family.
* BewareTheNiceOnes: As seen in her EstablishingCharacterMoment. Ruri may be kinder and gentle than her other counterparts, she's still a TechnicalPacifist who had her home invaded and is filled with hatred for the aggressors. Afterward, Ruri becomes a full-blown ActionSurvivor when learning the AwfulTruth.
* BrokenBird: She may be a gentle and kind girl, even after watching her home being invaded by Academia, but the war has truly taken a toll on her mental state, even more so when discovering the AwfulTruth.
* BroodingBoyGentleGirl: The compassionate and gentle girl to Yuto's stoic and brooding boy. However, this becomes averted later on with the two becoming gender-inverted examples for a while before losing this dynamic entirely in chapter 13.
* CombatPragmatist: Justified as she's fighting in a war, leading to her using any card advantages against the Obelisk Forces.
* CynicismCatalyst: Like with everyone in the Xyz Dimension, the invasion of Heartland by the Academia forces causes a lot of trauma for Ruri, and learning the AwfulTruth from Ray is the final push for her to become an AloofAlly.
* DoesThisRemindYouOfAnything: Whenever she and Yuto confide with each other in private, their intimate moments can be seen as a '''PG-13''' SexForSolace.

* FantasticRacism: Beneath that kind and gentle exterior lie not only sadness but also an unrelenting hatred for Fusion Summoning, especially when Academia uses the Extra Deck Summoning mechanic to invade Heartland. However, this becomes downplayed after learning the AwfulTruth and agreeing to learn Fusion Summoning, but Ruri is still very reluctant to use it.
* FriendToAllChildren: Even after her attitude changed to be more pessimistic and stoic, she still cares about the children who were suffering in Heartland.
* GirlyGirlWithATomboyStreak: Before the Xyz invasion, Ruri tends to climb trees whenever she and Shun went to the park to hang out with friends.
* HappilyAdopted: Like with Yuzu, Ruri is happily part of Shun's family. Too bad it doesn't last long as their parents were both carded by the Academia Forces during the initial invasion.
* HiddenDepths:
** She may be gentler and ladylike than her other three counterparts, but she isn't as mentally stable as she appears to be since the invasion of Heartland. The moment Ruri saw Serena in their mindscape and deduced that the latter was from Academia, she quickly flare-up in anger when Serena [[InnocentlyInsensitive innocently]] replies "Yeah, what of it?".
---> "[[SuddenlyShouting What of it... WHAT OF IT?!]] I'll show you 'What of it' right now with a --" (Cue her OhCrap moment when realizing her missing Duel Disk)
*** Even then, she goes on an angry rant by calling Serena and the Obelisk Forces "heartless monsters" for invading her home and making them live in fear, which almost leads to a physical altercation between the two had Ray didn't intervene with her introduction.
** Before the invasion, Ruri loves to visit coffee shops and hang around with other girls, try on various new hairstyles, and would try to climb a tree whenever she and Shun go to the park.
* TheHeart: She often serves as the gentle and reassuring member of the Resistance, and particularly to Yuto and her brother Shun.
* {{Irony}}: When compared to Yuzu, Rin, and Serena, Ruri is notably more gentle and ladylike than their {{Tsundere}} behavior. Then after the revelation of why Heartland's been invaded and her own role in The Professor's plans, she becomes much, ''much'' more ruthless and pragmatic than her counterparts (and not without good reason due to her living in a warzone). In chapter 10, she essentially had a '''mental breakdown''' when learning about the Fusion Parasites, leading to her spewing hate-filled rants of brutalizing Academia in tears as Ray and her other counterparts gave her a CooldownHug.
* LethalChef: [[PlayedForLaughs Hilariously]], she's a ''terrible'' cook compare to her other three counterparts (Yuzu regular cooks for her family, Rin can make meals from cheap ingredients, and Serena hasn't really learned cooking yet). In fact, she was forbidden from ever entering a kitchen again after ''burning water''.
* LivingEmotionalCrutch:
** If wasn't obvious, she serves as this to Yuto, the boy who she loves and is connected to on a spiritual level, and feeling is very mutual in return.
** To her older brother Shun, the thought of living in a world without her in it is something he can't ''ever'' fathom or accept. So much as he was willing to become Ray's "knight" and help with reviving her and Zarc. If anything, Ruri only had TearsOfJoy from her brother's conviction, and reciprocate their sibling bond with full force.
* LoveAtFirstSight: She had this when meeting Yuto for the first time as her brother introduces her to him.
* MoralityChain: She serves as this towards her older brother and boyfriend, keeping them from going off the deep end despite the hopelessness of the war. {{Deconstructed|Trope}}, however, as it's also a case of LoveMakesYouEvil since she's helping [[GreaterScopeVillain Ray and Zarc]] to revive them.
* OOCIsSeriousBusiness: After she TookALevelInCynic, all of her close friends were worried over this change of behavior, as she once strongly adhere to Yusho's Dueling philosophy and was overall gentle and pacifistic.
* PerpetualFrowner: {{Downplayed|Trope}}. She usually makes this expression after learning the AwfulTruth, and only tends to smile when talking to Ray and her counterparts.
* SharedFamilyQuirks: After [[TookALevelInCynic becoming more pessimistic and distant]] in her demeanor, Ruri acts much like her older brother.
* StatingTheSimpleSolution: When strategizing on how to take down Ancient Gear monsters used by the Obelisk Forces in chapter 2, she proposed that they used Trap Cards to destroy them upon their summoning, like Trap Hole and Widespread Ruin. It works as they also caused real explosions through the Solid Vision with Mass, making it easier to defeat the enemy Duelists and strip them of their decks and duel disks.
* StayInTheKitchen: Somewhat PlayedForLaughs and Subverted. She accuses Yuto of suggesting this DoubleStandard of her because of her new change in demeanor, only for the latter to quickly states it's not.
* SuddenlyShouting: Any time she starts raising her voice, expect things to go wrong at that moment.
* TechnicalPacifist: Due to her strongly believing in Yusho's Dueling Philosophy, Ruri was this during the invasion of Heartland, as she hated the idea of Dueling being used as a war tool but isn't above protecting herself or her loved ones if needed. Then later becomes {{subverted|Trope}}, as she ''rejects'' pacifism altogether and straight-up becomes a front-line ActionSurvivor in the Resistance.
* ThreeAmigos: She has this dynamic with her brother and boyfriend after the three of them are on the same page in chapter 13. This leads to Sayaka feeling uneasy by how the three "move and spoke with a strange union and synchronicity".
* TookALevelInCynic: [[AwfulTruth After the revelation of the invasion of Heartland and her own role in Leo's plans]], Ruri steels herself focus more on keeping her friends, family, and allies safe from the Obelisk Forces; all while becoming more cynical and distant. Of course, she's much more lively with Ray and her counterparts whenever they get together in their shared {{Telepathy}}. This soon becomes [[TookALevelInCheerfulness inverted]] in chapter 13.
* TraumaButton:
** Using the Fusion Summoning mechanic is one for her, and not unjustified due to what happened to Heartland. As she slowly learns to separate the tool and the user, this will gradually downplay into a subversion.
** Learning about the Fusion Parasites becomes a very big one for her, leading to a horrific [[HeroicBSOD mental breakdown]] as she screams in grief and her hatred of Leo and Academia has hit the point of no return, shouting out threats of murdering them. It took Ray and her other counterparts to give a big CooldownHug for a long while, and even after Ruri wakes up from the MentalWorld, she's ''still'' a sobbing mess as Yuto found her alone.
* WorthIt: As Ruri states to Shun when he brings up the possibility that Ray could just be manipulating her and not keep her promise about saving Heartland and herself existing, she would rather risk it than what Leo Akaba has planned for her, her counterparts, Yuto and his counterparts, and for the rest of the Four Dimensions.

[[folder:Rin]]
!!Rin
!!!'''Archetype''': Windwitch
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/rin_18.jpg]]

Yugo's childhood friend who also hails from the Synchro Dimension and grew up with Yugo as a part of the "Commons" in the slums of Neo Domino City. Like Yugo, she too dreamed of building a D-Wheel of her own and using her dueling skills to participate in the Friendship Cup to escape the hardships of her environment.\\\
After coming into contact with Ray and her other counterparts, Rin joins them to revive Zarc and grew closer to Yugo in the process.\\\
Her deck is a Windwitch deck, themed after winter, wind, and bells, which focuses on Burn Damage and copying effects from the Graveyard.

* AllWomenAreLustful: Compare to her other three counterparts, Rin proves herself to be much more sexually aggressive in her relationship with Yugo, especially how she's constantly seducing him with her body and new outfits, and her scenes with Yugo being intimate with each other are sexually arousing.
* AnIcePerson: In addition to the wind, she can also conjure ice into reality and isn't really bothered by the colder atmosphere.
* AscendedExtra: Moreso than her counterparts, as she was basically a SatelliteCharacter who gets the [[OutOfFocus least focus out of them all]] in the canon anime. Here, she's the protagonist of the Synchro Dimension side of the fic and is getting involved in a greater conspiracy than Ray and Zarc's revival.
* BareYourMidriff: In her casual wear, she wore a green tube top that exposes her midriff.
* BattleCouple: With Yugo.
* BikerBabe: She is a Turbo Duelist after all, and her curves, especially her chest and rear, are accentuated with her new riding outfit, completed with a SpyCatsuit aesthetic and a slight CleavageWindow.
* BlowYouAway: She uses the Windwitch archetype, which is full of WIND Spellcasters. She can also manifest cold winds into reality.
* CleavageWindow: She invokes this when showing off her new riding outfit to Yugo, and zip it up fully as they join Akiza for the day.
* DeadpanSnarker: She occasionally does this at times.
* DeathGlare:
** She first appears in the story having a severe expression, which makes Yuzu feel uneasy.
** She gives a very, ''very'' deadly one to Professor Frank. Especially when he nearly succeeds in his MindRape of her.
* DoesThisRemindYouOfAnything:
** Her duel with Professor Frank and how [[MindRape she gets slowly hypnotize to the point of letting him into the depths of her mind]] is disturbingly filled with ''rape allegories'', and throw in the latter's medical occupation in the mix only makes this [[{{Squick}} creepier]].
** In chapter 16, Yugo bit Rin's shoulder, which according to Zarc it was a natural thing for a dragon to claim his loved ones in such a way. Rin let it happen, placing her full trust in Yugo, and in response, she let out a huge burst of ice spikes as she gasped in pleasure. Needless to say that that moment was as close to a show of PG-13 sex.
* DoubleStandardAbuseFemaleOnMale: She often hit and scolds Yugo a lot for his usual antics, especially when it's usually unnecessary. This becomes {{averted|Trope}} after her first meeting with Ray and realizing her own romantic feelings for Yugo, as she becomes quite gentle and affectionate to the latter after a few days.
* GoodThingYouCanHeal: Rin's duel with Akiza was brutal, to say the least, Rin was wounded and bleeding to the point of almost not seeing straight, had it not been for Ray's help and her natural Siren powers Rin would have been worse for wear.
* HiddenDepths: Apparently, she had an interest in learning about witches and spellcasters, which involves reading short stories about them, looking through grimoires, making notes of them, trying to make her own spells, and believing that the power and potential of magic hold new possibilities.
* HowDoIShotWeb: Despite learning the process of Xyz Summoning from Ruri, she hadn't grasped the lesson and made the error by sending her monsters ''to the GY instead of stacking them together''. When Ruri heard of this mistake, she can't help but laugh in amusement.
* InterclassFriendship: Being born at the poverty line, specifically in the lower-middle-class, any friendship she has other than Yugo or those of similar class is this by default.
** A good example would be with Ray and her other three counterparts; Ray is from an upper-class background, Yuzu is the adoptive daughter of the You Show Duel School's principal, Ruri is, at least, from a middle-class background with her adopted family, and even Serena was living like a sheltered princess in Academia.
** With Akiza, as the former is well off to the point of being able to shop at the mall district in the Tops.
* ItAmusedMe: The reason why she wasn't going to intervene when Serena and Ruri were about to fight was this.
* KickTheSonOfABitch: She really let Professor Frank have it for his near successful MindRape of her, by punching him in the face with her ice-laced fist after brutally defeating him in their Duel.
* MindRape: She undergoes this from Professor Frank. When Zarc and Yugo manage to snap both her and Ray back to their senses, Rin ''really [[ThisIsUnforgivable didn't take it well]]''...'''''[[KickTheSonOfABitch at all]]'''''.
* MsFanservice: She knows how much Yugo is attracted to her, so Rin [[InvokedTrope milks]] this trope for '''all''' its worth to him, and her new outfits show off her curves in ''all the right places''. Safe to say, Yugo is certainly ''not'' complaining here.
* NervesOfSteel: It says a lot that she doesn't even flinch when interacting with Akiza, who's infamous as the Black Rose Witch. Justified from her own experiences with Ray and her other counterparts, along with her own personal hobby of witches.
* OnlyInItForTheMoney: It's one of the reasons why she and Yugo are participating in the Friendship Cup, so they could raise themselves out of poverty.
* OnlyOneName: Which is lampshaded with her counterparts.
-->'''Ruri''': Just Rin?\\
'''Rin''': Just Rin.
* OutOfCharacterAlert: You would forgive Yugo for being a bit weirded out by Rin's change in behavior, as she usually tends to scold him for acting out in certain ways and even hitting him if she feels particularly annoyed or embarrassed. That being said, he really can't complain that she now reciprocates his feelings for her and being quite gentler and arousing towards him.
* ProudBeauty: Although this applies to all of the Siren Girls, as part of their inherent nature, Rin takes it further by her invoked MsFanservice, and spends most of her interactions with Yugo wearing "certain" clothing to entice him. This lampshaded by Ray to Yuzu in chapter 17.
--> '''Ray:''' "What Rin did requires a certain kind of self-confidence and a level of carelessness to own what she wore. I mean, could you see yourself in a small top and short shorts walking around the city?"\\
'''Yuzu:''' (embarrassed at such a scandalized image of her) "Um… I…"\\
'''Ray:''' "Exactly, you're not wired that way sweetheart, and that's okay.
* RelationshipUpgrade: She reciprocates Yugo's feelings for her and the two became a couple in chapter 5.
* SirSwearsALot: She's the most foul-mouthed of her other three counterparts, and is most likely to shout profanity at times.
* ShesGotLegs: Along with BareYourMidriff, Rin also wears black shorts that expose her legs.
* TheTease: What she does with Yugo by invoking a MsFanservice on him to awaken his inner darkness. It's working more than ever.
* TookALevelInBadass: Enough to the point where she catches the attention of Akiza and ''Divine'', and it's possible that she could've given Yugo enough trouble in their own duel had she really [[HowDoIShotWeb learn how to use Xyz Summoning properly]].
* TookALevelInKindness: As she realizes her own romantic affections for Yugo, she becomes much more openly affectionate with him and practically drops her usual rough tendencies to hit and scold him for his antics. To show how much kinder she had become, Rin never so much as getting angry or violent when Yugo [[WhatTheHellHero angrily accuses her]] of "pretending" to love him romantically in chapter 16.
* [[WorkingClassHero Working Class Heroine]]: In contrast to Ray and her other counterparts, Rin is a Common who lives in the lower class of Neo Domino City, and she aims to participate in the upcoming Friendship Cup to raise herself and her boyfriend out of poverty.

!The Dragon Boys
[[folder:All four]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/dragon_boys.jpg]]
* AdaptationalVillainy: In the canon anime, Yuya, Yugo, and Yuto were the only three of the four counterparts who rejected Zarc's influence, contrasting Yuri who embraces his inner darkness. Here, due to Zarc being kinder, all of them accepted Zarc's power and agreed to help revive him and Ray.
* DemotedToExtra: {{Downplayed|Trope}}. Yuya is TheProtagonist of the canon series, with each of his counterparts getting their own spotlight in the show. Here, they're the [[{{Deuteragonist}} Deuteragonists]] to their respective Siren Girl.
* OnlyOneName: Except for Yuya, the other three don't have last names.
* RelationshipUpgrade: They become much closer to their respective Siren Girls; Yuya and Yugo are now dating Yuzu and Rin respectively, Yuto and Ruri are more open about their relationship, and Yuri and Serena are becoming PlatonicLifePartners.
* {{Reincarnation}}: They're this to Zarc of the Original Dimension.
* RotatingProtagonist: Rotating ''Deuteragonist'' as whichever chapter focuses on a particular Siren Girl, expect them to be the main secondary character.
* LivingEmotionalCrutch: All of them are this to their respective Siren Girls, and vice versa.

[[folder:Yuya Sakaki]]
!!Yuya Sakaki
!!!'''Archetype''': Performapal/Odd-Eyes
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/sakaki_yuya.jpg]]

Yuzu's childhood friend and the son of You Show Duel School's founder. He aspires to become an Entertainment Duelist and bring laughter to people through his duels as his father did before him, at least before Yusho's mysterious disappearance three years ago.\\\
He owns a good-luck charm pendant his father gave him when he was younger, which mysteriously glows during his televised exhibition match against Strong Ishijima. This unlocks the power of an entirely new Summoning method, Pendulum Summoning.\\\
He uses a Performapal Deck, which features animals in costumes that focus on altering the ATK and DEF of monsters; he later starts incorporating the Odd-Eyes archetype. His ace is his Odd-Eyes Pendulum Dragon, one of the four Dimensional Dragons.

* AdaptationPersonalityChange: Since Joey and his friends are in this fanfic, they keep him from becoming too much of a StepfordSmiler.
* AdaptationalEarlyAppearance: His Rune-Eyes Pendulum Dragon shows up much earlier than canon.
* AllTheOtherReindeer: Due to his dad disappearing, nearly every kid his age mocked him. This soon becomes subverted after his Duel against Strong Ishijima.
* HeroicBSOD: PlayedForLaughs. When Yuzu gives him a BigDamnKiss in chapter 9, his brain short circuits as he wonders if he's dreaming at that point.
* TookALevelInBadass: Decides to start training and experimenting with Pendulum monsters sooner than in canon and doesn't take as much time to learn how to set a Pendulum Scale, to the point that he can beat Yuzu -- who just learned Fusion and Xyz summoning -- in a duel.
* RelationshipUpgrade: Yuya and Yuzu became a couple after the former's victory over Strong Ishijima.

[[folder:Yuri]]
!!Yuri
!!!'''Archetype''': Predaplants
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/yuri_64.jpg]]

A member of Academia under the direct command of Professor Leo Akaba. He is Yuya's Fusion Dimensional Counterpart, due to them sharing the same face and originally being of one entity, "Zarc".\\\
He was sent by the Professor to capture Yuzu Hiragi. However, doing so awakened Ray in Yuzu and the other Siren Girls made them aware as to what Akaba is planning for them and empowered them (along with Yuri becoming an ally with Ray).\\\
He utilizes the Predaplants, a legion of DARK Plant-type monsters that can swarm the field, impairs and ensnares opponents with their effects, and sets up ideal conditions for his ace monster, Starving Venom Fusion Dragon.

* TheAce: He's known to be the strongest and smartest student in Duel Academia, and he's capable of defeating three Obelisk Blue students on his own, ''simultaneously''.
* AgentPeacock: A flashy dresser and a dangerous duelist.
* AllegedLookalikes: Although Yuzu first mistakes him for Yuya, she quickly deduced that he isn't the latter.
* AmbiguouslyGay: Yuri tends to dress in a rather flashy outfit, speaks very politely, has flamboyant mannerisms, is a CaringGardener (which is traditionally seen as an unmasculine hobby), has a GenderBlenderName[[note]]In Japan, Yuri means "Lily" and it's typically a feminine name.[[/note]] (to which Ray affectionately calls him "Lily"), and is described to have "pretty" eyes. Furthermore, there're some hints of ArmouredClosetGay as according to him, he will sooner teach someone a lesson if they so much as tease him for being feminine. Additionally, he's the only Dragon Boy whose close relationship with his respective Siren Girl being [[PlatonicLifePartners platonic]], rather than romantic.
* BadassCape: A short red one resembling Yuya's coat.
* BadassLongCoat: He wears also a coat since his cape isn't long enough.
* BecauseYouWereNiceToMe:
** The reason why he's so loyal to Leo Akaba is due to the latter acknowledging him as everyone else is too afraid to interact with him. This loyalty later goes away when learning of what he truly was to The Professor from Zarc.
** Ray's familial kindness and love for Yuri is what made him turn to help her and Zarc to revive in the first place.
* BewareTheSillyOnes: Even his basic speaking is theatrical and rather silly. Make no mistake, he's just as capable of switching to sadistic and deadly serious.
* BloodKnight: He's always up for a good duel, especially if it means he could test his strength against others with his ace monster.
* CardCarryingVillain: He's much more bloodthirsty and sadistic compare to his counterparts and is more willing to embrace this status.
* CurbStompBattle:
** He does this to Yuzu in the very first chapter. He used a Fusion Spell Card to fuse two of her ''own'' monsters to Fusion Summon a monster of his own, and would have defeated her if it weren't for Ray taking control to [[InvertedTrope invert]] this on '''him'''.
** He does this to three Obelisk Blue students off-screen in chapter 10.
* DarkIsEvil: His Predaplants and Starving Venom Fusion Dragon are all DARK Attribute, and is the only one of his other counterparts to be a CardCarryingVillain to them potentially becoming an AntiVillain.
* DefectorFromDecadence: He defects from Leo and Academia to help Ray and Zarc to revive them.
* DesperatelyCravesAffection: It's even in his ace monster's name. Despite his prideful nature and his seeming distaste for affection, Yuri craves for it deep down. It's what led to him defecting from Leo and Duel Academia when feeling the affection given to him by Ray for the first time.
* EvenEvilHasStandards: Is utterly disgusted by The Professor's plans to control Ray and her counterparts via parasites.
* TheEvilPrince: Due to being a reincarnation of a demonic draconic god-king, Yuri is this.
* OurDragonsAreDifferent: Starving Venom Fusion Dragon is a Dragon-Type monster. It's a kind of humanoid dragon that has a snake-like appearance and plant-like characteristics.
* PlatonicLifePartners: With Serena.
* PowerCopying: Starving Venom can not only gain the total ATK of a Level 5 or higher monster the opponent controls but also copy the name and effects as well.
* PurpleIsPowerful: His hair color, eye color, uniform, and ace monster is all purple in color, and he's acknowledged as one of the strongest Duelists in Duel Academia along with everyone else fearing him as TheDreaded.
* RelationshipUpgrade: A [[PlatonicLifePartners platonic]] example with Serena.
* SmugSmiler: This is usually his default expression, and not unjustified due to his strength as a Duelist. Any time he stops doing that is usually out of annoyance or genuine anger.
* TookALevelInKindness: Somewhat... but he becomes much kinder in his interactions with Ray and Serena.
* {{Troll}}: He ''loves'' to do this. Zarc even warns Yuto about this aspect of him just to give him the heads-up before heading to the Standard Dimension with Ruri and Shun.
* UndyingLoyalty:
** He had this for Leo Akaba, [[SubvertedTrope at first]] since the man was the only one who acknowledged him whereas everyone else feared him. That being said, he would've later grown out of this anyway due to Zarc's influence.
** He later gains this for Ray and her counterparts, along with Zarc and his counterparts as well.

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/91d70b2b0e5347aa987a95ad4470ca8c.jpg]]

One of the survivors of the invasion on the Xyz Dimension, as well as a member of Resistance. He is Yuya's Xyz Dimensional Counterpart.\\\
He uses a Phantom Knights deck that focuses on summoning Xyz Monsters, including his Dark Rebellion Xyz Dragon, and makes use of Spell and Trap Cards that can be activated from the graveyard.

* BroodingBoyGentleGirl: The stoic and brooding boy to Ruri's compassionate and gentle girl. However, this becomes averted later on with the two becoming gender-inverted examples for a while before losing this dynamic entirely in chapter 13.
* DarkIsNotEvil: Played With. His ace monster and deck are all DARK Attribute monsters, his own appearance has a dark motif, and as a reincarnation/fragment of Zarc, is associated with darkness. However, Yuto is very much a NiceGuy, and could potentially be an AntiVillain at best.
* DoesThisRemindYouOfAnything: Whenever he and Ruri confide with each other in private, their intimate moments can be seen as a '''PG-13''' SexForSolace.
---> Ruri sat up straighter and ran her hand through Yuto's hair and down his cheek, before pressing their foreheads together. "We're all in constant anxiety and fear, smiles are few and fleeting, so any happiness, any small comfort that we can take from each other... it's alright to ask," she whispered, giving Yuto's lips another kiss. Ruri broke the kiss slowly but Yuto pulled her in for another, the kiss became heated and Yuto's hand threaded through Ruri's hair, while the other one was placed between her shoulder blades. Yuto's lips kissed down Ruri's jaw and down her neck as she clung to him, placing her palm over the back of his neck and the other grabbed his shirt. After a while Ruri sat on Yuto's lap, as she buried her head in his neck, Yuto ran his hand through her hair, taking comfort in each others' arms, breathing each other in, so familiar and comforting, yet making the fear grow, the fear to lose all of this, the little happiness between them, the small sweet comfort, making them fight for a new day.
* DraconicHumanoid: In his dream, he's described to have draconic features that are similar to his ace monster.
* FantasticRacism: Despite his kindness, he hates Fusion and those who use it, specifically Academia for their use of the Extra Deck Summoning mechanic to invade Heartland. However, this starts to become downplayed in his meeting with Zarc upon learning the AwfulTruth, his other counterparts (especially Yuri), and Ruri's willingness to learn Fusion if it means it'll help the Resistance in the Interdimensional War.
* LoveAtFirstSight: He had this upon meeting Ruri for the first time as Shun introduces her to him.
* PowerLossDepression: {{Inverted|Trope}}. When he finally accepts Zarc's power, he becomes much more lively than his usual stoic demeanor.
* PerpetualFrowner: He rarely smiles after the invasion of Heartland.
* TheSacredDarkness: Ruri describes him as "the night sky", and his Phantom Knight deck and ace monster are more reminiscent of this rather than the stereotypical DarkIsEvil.
* TookALevelInCheerfulness: As he accepted Zarc's power, Yuto becomes much more lively and hopeful, and is mentioned to be more open with his romantic relationship with Ruri.
* WhenHeSmiles: Whenever he does smile, it shows the rare times he had peace since the invasion started.

Rin's childhood friend who hails from the Synchro Dimension and grew up with Rin as a part of the "Commons" in the slums of Neo Domino City.\\\
He uses a deck with Speedroids, Wind-Machine Type Monsters that resemble toys or are references to games, primarily those centering on dice. Yugo also relies on luck as a powerful factor in his duel style and all his monsters lead up to supporting his ace monster, Clear Wing Synchro Dragon.

* AmazonChaser: If there is one thing we know for sure is that Rin is no meek girl, in fact, she would easily dropkick and punch anyone who annoys her, her anger is terrifying and Yugo absolutely is head over heels in love with her and admires that power, in fact, it turns him on when he sees Rin demonstrating how strong she is, physically, mentally and mystically.
* BigDamnHeroes: Arrives just as Professor Frank as Rin in his clutches, giving her the mental strength to kick him out.
* BiteOfAffection: As a dragon guided by his instinct at that moment, Yugo had the great urge to bite Rin and claim her as his, to show his love and protection of her as well as possessiveness, in his mind Rin becoming his treasure to hoard.
* CasualKink: Implied to have this as he really isn't bothered by Rin's constant sexual aggression.
* BlowYouAway: He's described by Rin as "like the wind", and his ace monster and Speedroid deck is WIND Attribute.
* CutenessProximity: Squees at Akiza's White Rose and Red Rose Dragons, wishing to just take him home and spoil them rotten.
* EatingTheEyeCandy: Does this a ''lot'' whenever Rin dresses provocatively, which is exactly what she aimed for.
* HotBlooded: He tends to listen to his heart rather than use his head at times.
* RelationshipUpgrade: Much to his delight, he gets his feelings returned by Rin and became a couple.

Here he's capable of dueling on his own with Xyz monsters and has beaten his boyfriend [[TheAce Atem]], ''several times'' in the past, and know this, Atem is regarded as the KingOfGames and ''the only Duelist to beat'' '''Reiji''' ''of all people''!
* AdaptationalSexuality: Compare to his straight canon counterpart, who had feelings for his ChildhoodFriend Téa, this version is in a same-sex relationship with Atem.
* BadassAdorable: Small, sweet, with big innocent amethyst eyes...and capable of defeating you in a duel while down to 100 life points.

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/maximillion_pegasus.png]]

The uncle of Mahad, Atem, Mana, and the current President and CEO of Industrial Illusions.

* BunnyEarsLawyer: Make no mistake that Pegasus is eccentric but he's also a very smart and successful CEO and is quick to help Yuya make a business deal that actually benefits the boy.
* CoolUncle: To his nephews and niece, as seen in chapter 4.
* DubNameChange: He's known by his dub name instead of his original Japanese name, ''Pegasus J. Crawford''.
* {{Manchild}}: A given. When he meets with the limo driver he states that the in-flight entertainment bored him...and quickly gets excited when he learns there's a copy of ''Yotsuba'' in the limo.
* RelatedInTheAdaptation: He's a the adopted uncule of Mahad, Atem, and Mana in the fic.
* StealingTheCredit: A rare ''positive'' example. Knowing that Yuya would be called a cheater for creating an entirely new summoning mechanic, Pegasus offers the boy to take credit for inventing Pendulum Summoning and saying that Yuya was testing it, while giving Yuya and his mother a share of the profits.

!!Leo Corporation
A company founded by Leo Akaba that specializes in Duel Monsters and Duel Disk as well as creating various Duel Schools known as Leo Duel School. After Leo disappeared and abandoned his family his son Reiji took over and became the new CEO.

[[folder:Reiji Akaba]]
!!Reiji Akaba
!!!'''Archetype''': DD/DDD
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/reiji_akaba.png]]

A prominent duelist and a CEO of Leo Corporation. He has a sour grudge towards his father Leo Akaba for abandoning him and his family and aims to defeat his father and Academia in order to stop his evil ambition.

* AdaptationalHeroism: While Reiji is no less capable of committing as many morally questionable acts to achieve his goals as his canon counterpart, his early AmbiguouslyEvil acts of "acquiring" Yuya's Pendulum cards are AdaptedOut thanks to Pegasus StealingTheCredit for the creation of the Pendulum Summoning mechanic in a contract with Yuya and his mom to prevent the boy from getting accused of cheating in his duel against Strong Ishijima, and receiving financial compensation.
* AdaptationalIntelligence: Reiji's plans for creating the Lancers are more thought-out as he intends to have another group of them bring aid to the Xyz Dimension.
* AgentMulder: Reiji is more open-minded about the supernatural and unknown this time around, believing that some other force is what was responsible for Yuya's Pendulum cards.
* DemotedToExtra: In the canon anime, he was Yuya's main rival and the BigGood of his series. Here, he's one of the supporting characters and doesn't get much screen time when compared to his original version, since the story mainly focuses on Ray, Zarc, the Dragon Boys, and the Siren Girls.
* SmartPeopleWearGlasses: Sports a pair of red square-rimmed glasses and is a ChildProdigy who's capable of being TheChessmaster when it comes to business and dueling.
* TheSpock: He is very analytical and logical most of the time.
* TheStoic: He rarely smiles after his father abandoned him and displays a calm, collected, and no-nonsense attitude.
* ThirdWheel: Although he isn't really friends with Yuzu and Yuya, he does felt rather awkward when seeing the two interact with each other in chapter 12.
* YouRemindMeOfX: Chapter 10 has Pegasus note that Reiji reminds him of Kaiba due to him being TheSpock. Humorously, this is fitting since Reiji was also a [[CompositeCharacter Composite]]/ContrastingSequelMainCharacter of Kaiba in canon.
* YoungAndInCharge: He's only 16, but is the current CEO of Leo Corporation.

!Xyz Dimension
!!The Resistance
The remaining Xyz duelists who haven't been captured by Academia; are the last remnants of a world that's gone to hell due to dimensional invaders. The Xyz dimension was originally a peaceful place to live in before they were attacked without warning. After repelling against most of the Obelisk Forces, duelists of the Resistance were able to procure the same technology as their enemies and can now inflict real damage on their opponents and sealed them away into cards.

[[folder:Shun Kurosaki]]
!!Shun Kurosaki
!!!'''Archetype''': Raidraptor
[[quoteright:270:https://static.tvtropes.org/pmwiki/pub/images/kurosaki_shun_3.jpg]]

Shun Kurosaki, along with Yuto, is one of the survivors of the invasion on the Xyz Dimension, as well as a member of Resistance. Originally a kind, if a somewhat stoic person, the invasion took its toll on his psyche. What makes this worse is learning that the true reasons why his home was destroyed and his younger sister Ruri, being planned as a "sacrifice" along with his best friend Yuto, being intended to get killed off by The Professor. He later joins up with Ray as her "knight" to ensure the safety of his loved ones and to make Academia paid for their transgressions.\\\
Shun uses a Raidraptor deck, which is made for swarming Winged-Beast-Type monsters to Xyz Summon monsters with low base-ATK, but powerful effects. He also has many Spell and Trap Cards that can counter various situations and exploits his Rank Up spells to evolve his Raidraptors into more powerful forms.

* AdaptationalAngstUpgrade: In the anime, Ruri being captured by Yuri causes Shun to really start [[SanitySlippage losing it]], and soon became a HeWhoFightsMonsters AntiHero. When being enlightened by the AwfulTruth of the Dimensional War along with the fact that his sister and best friend are to be sacrificed and killed respectively, his thirst for vengeance and hatred goes past the point of no return.
* AdaptationalNiceGuy: Compare to his canon counterpart, who's already a {{Jerkass}} HeWhoFightsMonsters AntiHero at the start of the story, Shun's relatively "nicer" here due to Ruri never having to be kidnapped by Yuri. Furthermore, his BigBrotherBully and ControlFreak tendencies of his sister are relatively toned down here.
* AdaptationalVillainy: At the beginning of the canon anime, he was already a GoodIsNotNice AntiHero [[JumpingOffTheSlipperySlope skirting onto the edges]] of a NominalHero. Here, he fully becomes an AntiVillain since he's helping [[VillainProtagonist Ray]] to ensure the safety of his sister and best friend.
* AntiVillain: After chapter 13, he falls into this role since, despite helping the revival of Ray and Zarc, his goals firmly lie in protecting his sister and best friend, helping the ones they care about, and rebuilding their home after it was laid waste by the Academia Forces.
* BadassLongcoat: He wears a long blue-purple coat and looks tough with it.
* BigBrotherInstinct:
** Ruri may not have been blood-related, it doesn't stop him from being a very doting brother if a little overprotective. So much as he's willing to make a pact with Ray to revive her and Zarc as long as she ensures that Ruri will be still alive in the end.
** He also extends this to Yuto and included his safety as well in his pact with Ray.
* ChessMotif: The Knight, as he serves as Ray's agent in chapter 13.
* CyberneticsEatYourSoul: Metaphorically; his Raid Raptors monsters resemble robotic avian predators, which symbolizes his desire to protect his sister and PayEvilUntoEvil on his foes. However, his devotion to his sister is what Ray recognizes as a good trait.
* DarkIsNotEvil: Played with. Despite his dark attire and joining up with Ray to revive her and Zarc, Shun cares more about protecting his loved ones and hurting those who try to harm them.
* DeathFromAbove: A recurring motif of his Raid Raptors, with Revolution Falcon burying the Obelisk Forces under a hail of bombs in his nightmare.
* EvenEvilHasStandards: Despite being willing to commit morally unconscious acts in order to protect his sister, best friend, and homeland, Shun is quite disgusted by learning how petty Leo's motives are in order to revive his daughter.
* FantasticRacism: Considering what the Obelisk Forces had done to his home, he hates Fusion Summoning. Although this is rather downplayed thanks to Ray and his sister, focusing his hatred on Academia rather than fusion users in general.
* HeterosexualLifePartners: With Yuto, as the two are best friends from thick to thin.
* KarmicJackpot: A villainous example. His love for Ruri is recognized by Ray, who's very happy that her counterpart had such a loving family member and would anything to protect her and their friends. This leads to him being gifted by both Ray and Zarc with his own powers and gain new cards as well.
* KnightTemplarBigBrother: He will do ''anything'' to make sure that Ruri is alright, and he extends to Yuto to a lesser extent. It's also what causes him to ally himself with Ray and Zarc in the first place.
* MagicKnight: A pretty good duelist in a world where duel monsters can be implemented with real magic and is a skilled hand-to-hand fighter capable of taking down several enemies at once. This is much more apparent with Ray and Zarc empowering him with his new cards.
* LoveMakesYouCrazy: His love for his sister Ruri makes him very erratic in his willingness to protect her, which Ray finds endearing.
* LoveMakesYouEvil: He later joins up with Ray into reviving her and Zarc to protect Ruri.
* NoHoldsBarredBeatdown: It's what he ''intends'' to do to The Professor, as his brief fantasy shows, it involves grabbing the man by the throat and bashing his skull against his own throne repeatedly. [[AdaptationalKarma And unlike canon, it's probably going to happen compared to his almost punch at the man]].
* NotSoStoic: He drops his stoicism whenever Ruri or his allies' lives are at stake.
* PowerLossDepression: {{Inverted|Trope}}. As he gains power by accepting the two cards gifted to him by Ray and Zarc, he becomes much more lively.
* TheStoic: He becomes very cynical and emotionless after Academia invaded his home.
* ThreeAmigos: He has this dynamic with his sister and best friend after the three of them are on the same page in chapter 13. This leads to Sayaka feeling uneasy by how the three "move and spoke with a strange union and synchronicity".
* TookALevelInBadass: In chapter 13, he gains powers like his sister and best friend, and his deck gains two more cards from Ray and Zarc respectively.
* TookALevelInCheerfulness: He became very depressed and stoic after Academia destroyed his home, but after accepting two cards gifted to him by Ray he becomes more lively.
* YouAreWorthHell: "The only truth I know is that Ruri is my sister, my family. Nothing will change that, nothing could make her any less important to me."

!Synchro Dimension
!!The Enforcers/Monarchs

Four duelists from the Commons banded together to bring peace between them and the Tops. Jack was originally sent into the Friendship Cup to become King, but after he was influenced by Roget, his fellow Enforcers intervened and placed Yusei as the head, and the four to help heal the divide between the two classes.

* AdaptationalBadass: All of them have some sort of strange power to them: Yusei controls electricity, Jack controls fire and Kalin can manipulate shadows. This is even noted in-universe as Armstrong, Grady and Carly note that there were rumors that they had special abilities.
* AdaptationalSexuality: Compare to their heterosexual canon counterparts, all four of them are in a four-way romantic relationship with each other.
* BigGood: To the entirety of Neo Domino City, as they manage to bring order to the society by abolishing the City's [[SocialDarwinist highly competitive culture]] and [[SpannerInTheWorks threw a huge wrench into Roget's plans]].
* DarkIsNotEvil: They either have dark-looking monsters or appearances, and they also have edgy-sounding nicknames, but they're all on the side of good.
* TheDreaded: ''All of them'' are this to most of Neo-Domino. To give an example, seeing Kalin enter Bootleg -- to get Yanagi away from Armstrong -- has an ''everyone in the bar'' run away in terror and for Grady and Carly to realize they're ''fucked''.
* DubNameChange: WordOfGod kept their dub name for the group instead of the original Japanese one (Team Satisfaction), as she states that the Japanese name sounded stupid.
* HeroOfAnotherStory: Their story of how they manage to foil Roget's plans by taking back control of Neo Domino City and abolishes the City's highly competitive culture, is a tale worth telling.
* MythologyGag: In their backstory, they created a safe haven known as "Satisfaction Town", referencing the Crashtown arc.
* {{Polyamory}}: All of them are a foursome of wholesome satisfaction.
* RedBaron: All of them have badass titles: Kallen is "The Shinigami", Jack is "Hell's Harbinger", Yusei is "Stardust Rider"/"King of Neo Domino" and Crow later gets "Black Omen". Crow even lampshades the fact that everyone else got cool names before him. Collectively, they're called the "Lords/Monarchs of Neo Domino".
* StraightGay: None of them display any stereotypical behaviors of homosexuals, as their personalities are relatively the same as their canon counterparts.

[[folder:Yusei Fudo]]
!!Yusei Fudo

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/yusei_fudo_2.png]]
The leader of the Enforcers, current champion of the Friendship Cup and King of Neo Domino.

* InSeriesNickname: He's affectionally called "King" by his fellow Enforcers.
* MustHaveCaffeine: Inverted. Yusei is '''not''' allowed to have caffeine as it makes him even ''more'' of a {{workaholic}}. The last time this happened, it took Jack, Crow, and Kalin to fuck him to wear him down. The reader sees what happens first hand after Randsborgh accidentally leaves a cup out for Yusei. It's apparently so bad that Jack won't even risk giving Yusei an ''iced tea''.
* OnceDoneNeverForgotten: The "Yusei with caffeine" moment with even Yusei complaining it was just one time.
* ProperlyParanoid: Was worried about the trouble Yanagi could get into when his fellow Enforcers reassured him the old man would be fine. Unfortunately none of them counted on Armstrong...
* ShockAndAwe: Has electrical abilities although they haven't been on display yet.
* TranquilFury: When significantly pissed off, he's capable of making ''Jack Atlas'' fear for his life.
* {{Workaholic}}: Yusei will work himself to death if it means making sure others don't have to suffer. It gets to the point that ''Jack'' has to pull him away and make him get some sleep. This is also very common as the other Enforcers have had to pull him away from work, whether it's papers, laptop or just dragging him from tuning up their D-Wheels.

[[folder:Jack Atlas]]
!!Jack Atlas

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/jack_atlas.png]]
Former king of the Friendship Cup and a member of the Enforcers.

* AdaptationalPersonalityChange: He's more humble than he was in canon. Justified in this case as he has his Enforcers to help keep his ego in check.
* GoodWearsWhite: He wears a white jacket and he's one of the Enforcers.
* LethalChef: Cannot cook to save his life. The idea of him making something for Yusei to eat elicits an AnythingButThat reaction from the latter.
* OnlySaneMan: Acts like this when Yusei works himself too much, having to drag him away to get some rest.
* OOCIsSeriousBusiness: It's noted that whenever Jack calls Yusei "King" that it's in a much more affectionate tone than when Kalin or Crow says it.
* PlayingWithFire: Implied to have fire abilities with security guards once having to put out fires that they had no idea where they came from.
* PuppetKing: He was this to Roget and the City Council in his backstory until Yusei manages to defeat him.
* RunningGag: Always likes to bring up Lady Fate to the point that Yusei states that Lady Fate hates him. The author notes lampshade this by stating that no, Lady Fate doesn't hate him; she just likes screwing around with him.
* TrademarkFavoriteFood: Still loves his instant ramen and coffee.

* InsultBackfire: When Armstrong says that he can't tell why Yanagi is needed, Armstrong states that it would go over his [Crow] "boyfriend's little head". Crow retorts that, aside from Jack, Armstrong has to be more specific since he has ''three'' boyfriends.
* OnlySaneMan: Compared to his fellow Enforcers, he's the most level-headed of the group, even lampshading why he doesn't get some badass title for his own.
* ThisIsGonnaSuck: After the wild goose chase against Armstrong and Yanagi and seeing news crew asking what happens, Crow realizes that ''Yusei'' has just seen all of this and is going to blow a gasket.

* AdaptationalHeroism: Was a Dark Signer in the anime, but a Crimson Signer in the fanfic.
* AdaptationalNiceGuy: Does ''not'' have his AxCrazy tendencies from the anime.
* AlliterativeName: '''K'''alin '''K'''essler.
* CastingAShadow: Is capable of summoning darkness, as he demonstrates with Carly. He also uses the Infernity archetype which is filled with DARK monsters.
* DubNameChange: Uses his dub name instead of his Japanese one (Kyosuke Kiryu) which makes him stand out to the other Enforcers keeping their original names.
* NamesToRunAwayFromVeryFast: Do ''you'' want to get on the bad side of the guy called ''Shinigami''?!
* ThisIsGonnaSuck: After learning about the Crimson Dragon Crusaders and how Armstrong led Crow onto a goose chase that was seen ''on live television'', all he can do is slam his head on a table knowing that Yusei is going to kill them.

!!The Crimson Dragon Crusaders

-->''"This is a new chapter in the history of the Randsborg name for we [Randsborg, Grady, Armstrong, Yanagi and Carly] are now a mighty group who are off to solve the mysteries of the Crimson Dragon. We have now become...the Crimson Dragon Crusaders!”''

Five duelists from the Synchro Dimension came together after seeing Rin dueling Professor Frank and Akiza's Crimson Dragon mark on her arm, diving into the mysteries involving their dimension.

[[folder:In General]]
* AscendedExtra: All five of them were secondary characters who had one duel throughout the entire series (barring Carly who had three). Grady gets this the most since he had little to no personality traits at all (due to being brainwashed at the time).
* FiveManBand:
** TheLeader: Gill Randsborg
** TheLancer: Dick "Grady" Pitt
** TheBigGuy: Mr. Armstrong
** TheSmartGuy: Tenzin Yanagi
** TheChick: Carly Nagisa
* HeroOfAnotherStory: Of the Synchro Dimension side of the fic, one where it involves the lore of the Crimson Dragon being unrelated to Ray and Zarc's revival, uncovering secrets of the Arcadia Movement, and subsequently learning that they're just one part of a bigger puzzle.
* LastNameBasis: Randsborg, Armstrong, and Yanagi are usually addressed this way.
* TheQuest: As Randsborg notes, their quest is to uncover the secrets of the Crimson Dragon, Zarc, and how Rin and Yugo are connected, and why the Arcadia Movement is so interested in them.
* RagtagBunchOfMisfits: They consist of a knight, an archaeologist, a former member of Security, a street duelist with a fondness of milk, and a [[spoiler:crossdressing]] reporter. Armstrong even lampshades that they're "a little ol' Breakfast Club".
* TheUnchosenOne: Despite their group name, none of them are chosen by the Crimson Dragon. Instead, they're just a group made up of individuals who grew curious about the world around them after witnessing the duel between Rin and Professor Frank.

[[folder:Gill Randsborg]]
!!Gill Randsborg
!!!'''Archetype''': Infernoble
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/jilldelancebeaux.png]]

A duelist who hails from a legendary family of knights. He is the first to bring up the legend of Zarc and the Crimson Dragon to the Crusaders.

* AdaptationalBadass: He used LV monsters called Masked Knights in his only duel while the narration states he uses Infernoble this time around.
* AdaptationalNiceGuy: Was an utter buffoon and believed that Akiza was a real witch in the anime, losing to her in a humiliating fashion. In the fanfic, he acts like the TeamDad for the Crimson Dragon Crusaders.
* AdaptationPersonalityChange: He was WrongGenreSavvy against Akiza in the anime, but here he knows well enough ''not'' to start BullyingADragon against her.
* HairOfGoldHeartOfGold: Golden hair and is a gentleman.
* HeroOfAnotherStory: His family has knowledge not only of Zarc, but also of the Earthbound Immortals and Crimson Dragon. What else have they been hiding?
* KnightInShiningArmor: Wears golden armor and is a chivalrous character through and through. Fittingly, he uses the Infernoble archetype.
* LargeHam: As befitting a knight, he likes to go on flowery tangents.
* NiceJobBreakingItHero: PlayedForLaughs. After he and Yanagi are allowed to bunk with the Enforcers to learn more about their powers, he left a mug of coffee for Yusei...not aware that Yusei ''must not have caffeine'' and has to see his fellow Enforcers dogpile Yusei before he works himself to death.
* TheNicknamer: Gives each of his fellow Crusaders different titles, "Valiant Grady", "She of Fair Eyes", etc.
* PlayingWithFire: He is said to have used Infernoble monsters, which are FIRE type.
* StrokeTheBeard: Does this as a {{Character Tic|s}} when in deep thought (even though, as the image shows, he doesn't have one).
* YeOldeButcheredEnglish: Speaks in this as part of being a knight.

[[folder:Dick Pitt (Grady)]]
!!Dick Pitt (Grady)
%%!!!'''Archetype''': ???
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/dick_pitt.jpg]]

A street duelist with a level head and a fondness for milk. He's the reconnaissance man who spies on Rin and Yugo about their powers.

* AdaptationalPersonalityChange: Had little to no personality in the anime and his ''only'' personality came from being a brainwashed goon for Yusei to duel. Here, he's the level-headed member and he's known to be concerned for whatever Carly is getting into and will protect her if she gets into trouble.
* AwesomeByAnalysis: Knew that Xavier Maxa was [[spoiler:Carly in disguise]] by picking up on his habits: stating that being near Armstrong was like living in the Pits (Carly's boss was Mr. Pitt) and bringing up Blue Eyes Mountain Coffees (an expensive brand that Carly knew Jack liked in the anime)
* CrazyPrepared: By the time Rin vs Akiza happens, he made it a habit to carry a parka and coffee since he knows that Rin's ice powers are not to be trifled with.
* CurbStompBattle: He and Carly are on the receiving end of one against Kallen.
* DarkIsNotEvil: Wears black and red and has black hair, but he's level-headed and has no malicious bone in his body.
* EstablishingCharacterMoment: Comes in to save Xavier Maxa from getting a beatdown from Armstrong to showcase that he's a mediator. [[spoiler:This becomes much more meaningful when the reader learns that he knows that Xavier is actually Carly in disguise.]]
* GuileHero: Goads Commander Koda to spill the beans about Akiza by spinning a lie about how Rin could come and freeze his ass off since Rin and Akiza started to become best friends.
* HiddenDepths: He trained under "Enjoy" Chojiro in diffusing fights according to the narration.
* InSeriesNickname: Insists on being called "Grady" instead of his birth name.
* LikeBrotherAndSister: His relationship with Carly in a nutshell as he wants to make sure she doesn't go over her head in regards to her investigations into Arcadia.
* MakingASplash: All that's known about his deck so far is that it's Water based.
* OffscreenMomentOfAwesome: He and Carly apparently fought off Arcadia Movement goons during Rin and Akiza's duel in the Friendship Cup.
* OnlySaneMan: Compared to the knight, the eccentric archaeologist, the grumpy Security guard, and the crossdressing reporter, he's considered to be the normal one. Armstrong even calls him "a level head".
* TakeMeInstead: Decides to take whatever punishment Kalin wants to inflict on him and Carly when Kalin accidentally touches Carly's chest -- as she was disguised as Xavier at the time -- but Kalin decides not to as they weren't his target.
* TrademarkFavoriteFood: He loves drinking milk and states that it won't make you crash or jittery like coffee.
* YouCalledMeXItMustBeSerious: Xavier calling Grady by his real name causes him to step back in fear. [[spoiler:Especially since Grady knows that it's Carly saying that to him.]]

[[folder:Mr. Armstrong]]
!!Armstrong
%%!!!'''Archetype''': ???
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/mrarmstrong.png]]

A former member of Security who, despite not really interested in the magic and nonsense, decides to tag along since he's got nothing better to do.

* ActuallyPrettyFunny: Upon seeing that Xavier had a Fortune Lady deck, he cackles at how he lost to a Fabled deck seeing as he would've had his ass handed if Xavier used the former.
* AdaptationalNiceGuy: Was a HateSink in the anime, to the point that ''Goodwin'' was disgusted by him. Here he's a bit of a grump and would rather ''not'' get involved with the chaos of the Synchro Dimension, but joins in when things start to get too deep. And his antagonism with Yanagi in the story is more on poor communication than him being a jerk.
* AdaptationalPersonalityChange: Instead of a huge jerkwad, he's more of [[JerkWithAHeartOfAgold a grump but not 100% a dick.]]
* CharacterTics: Blowing nose hairs out in public.
* DeadpanSnarker: Has very snarky remarks to all of the magic and mysticism that the group faces.
* DebtDetester: Only helping out with the crazy investigations because he hates giving out favors.
* DumbassHasAPoint: During Rin and Professor Frank's duel, he questions what's so important about Rin that the Professor is trying to hypnotize her. In fact, it's this question that spurs the Crimson Dragon Crusaders to do some investigating on their own.
* EveryoneHasStandards: He's an unpleasant jerk to be around but he has low esteem for [[BigBad Jean-Michel Roget]] and thinks that [[SmugSnake Professor Frank]] brainwashing Rin (a ''14-year-old girl'') is low. In fact, he personally was going to stop the duel himself if it continued. He also showed concern when Akiza's arm started to glow with her Crimson Dragon Mark.
* HoistByHisOwnPetard: The details of his duel against Xavier are vague but all we know is that his milling strategy ended up backfiring on him when Xavier's Fabled Leviathan was destroyed and he was able to retrieve three Fabled monsters from the graveyard (one of them being The Fabled Catsith).
* MisterExposition: He knows the most about Rin and Yugo and later reveals that he has heard rumors about [[spoiler:Security having Polymerization and Fusion Monsters]].
* NiceJobBreakingItHero: Nearly gets Grady and Carly into loads of trouble when he antagonizes Yanagi ''without'' explaining why he was chasing after the old man. Not helping that Crow and Kallen were ''also'' chasing him down since they knew each other in the past. He realizes his mistake when he learns how Crow has a Crimson Dragon mark.
* PoorCommunicationKills: Chases after Yanagi ''without'' explaining that he needs Yanagi's info about the Crimson Dragon nearly got him, Grady and Carly into loads of trouble when Kalin and Crow arrived and ''also'' needing Yanagi's help)
* SoreLoser: Subverted; he got mad when he lost to Xavier, but kept his cool and leave the arena without inciting a brawl.

* CoolOldGuy: He's a jovial fellow, the eldest member of the Crusaders and is the least serious member of the five.
* HeroOfAnotherStory: Whatever he's seen throughout his travels must be very interesting.
* IntergenerationalFriendship: Is good friends with Crow and Kalin, having met them when they were imprisioned in the Facility.
