Ryuji Otogi (御伽 龍児; Otogi Ryuuji) (Duke Devlin)
- Voiced by: Ryo Naitou (JP), Marc Thompson (EN), Luis Daniel Ramírez (Latin American Spanish), David Robles (European Spanish)"When determining victory or failure in a game, don't you use your opponent's weaknesses to win it?"
The son of the owner to Kame Game's rival game shop, the Black Crown, and an expert at Bar Bet games. His dad lost a Shadow Game to Yugi's grandpa, which disfigured his face horribly. He was raised to take revenge upon Yugi's grandpa by defeating Yugi in a game and taking his Millennium Puzzle, declaring himself the King of Games. Unfortunately for his dad, he eventually becomes good friends with Yugi instead. He's a talented gamer as well as a creator, and is responsible for the creation of Dungeon Dice Monsters (Dragons, Dice & Dungeons in the manga), a Strategy RPG originally created for the sole purpose of avenging his father and stripping Yugi of the title "King of Games" (among other games like Four Aces).
That's how it went in the original manga. In the anime, Ryuji was one of Pegasus' business partners and fans. Instead of being raised as a tool of vengeance by his father, he has a real grudge against Yugi over Pegasus' loss causing their business deals to stagnate, but he gets over it after the game hits it big. His personality in the anime is also different from his personality in the original manga. Unlike the manga where DDD was a completely separate game, in the anime he seemed to have based Dungeon Dice Monsters as a spin-off to Duel Monsters, incorporating many Duel Monsters creatures in the game as a tribute.
In the manga, aside from a one-off mention of liking Duel Monsters, he is never seen playing the Duel Monsters card game - we only see him playing "bar bet" games and Dungeon Dice Monsters, though he shows knowledge and interest in all games regardless. In the anime however, he is a big fan of Pegasus and is shown to play the game a few times. The first time he duels in the anime, he used a deck of cards randomly drawn from several booster packs. His true deck uses many dice effects, and many of the monsters emulate the ones that were originally from the manga's DDM. His strongest creature in Dungeon Dice Monsters is God Orgoth in both versions, which in the anime also has a Duel Monsters counterpart.
- Abusive Parents: In the manga. His dad raised him as a tool of vengeance and was seen whipping him after he found out he lost to Yugi in a game of Four Aces.
- Adaptation Explanation Extrication: The Black Clown's clown theme and Ryuji's partial clown are from the manga, where it comes from his father. No such explanation is in the anime; Ryuji apparently just likes clowns.
- Adaptation Personality Change: In the anime, he's a bit of a narcissist and a braggart, and tends to flip his hair and twirls his bangs. In the manga, he's more serious and quiet, and lacks the crush on Jonouchi's sister that his anime counterpart has later on.
- Alliterative Name: In the dub.
- Arrogant Gamer Guy: Initially appears as this in the manga, but ultimately subverted. Played straight in the anime.
- Ascended Extra: The filler arcs were kind to him in the anime, giving him more screentime and allowing him to duel a couple times, while in the manga he never got any such action after his introductory arc (essentially his gaming skills go to waste, and he's Put on a Bus during the Millennium World arc until the Ceremonial Battle).
- Badass Boast: Quite often when he challenges Yugi or Dark Yugi (depending on the medium) to Dungeon Dice Monsters, though it gets exaggerated in the anime's English dub.
- Beat Them at Their Own Game: Quite literally, he challenges Yugi to a game of his own creation which Yugi barely had any understanding of at first. But Yugi eventually managed to grasp the rules and turned the tables on him.
- Big Bad: In the anime's adaptation of the Dungeon Dice Monsters mini-arc. His father doesn't exist in the anime, whom he serves as The Dragon for in the manga.
- The Casanova:
- In the anime he makes it a point to be accompanied by his fangirl cheerleaders and also pursues Jonouchi's little sister.
- In the manga, the Bakura fangirls from the Monster World arc swoon over Ryuji during his first appearance at school, but he ignores them, and has no interest in Jonouchi's sister.
- Composite Character: In the manga, his father Mr. Clown owns the Black Crown game shop and holds a grudge against the Mutous, eventually deciding to use Otogi as his instrument of revenge. The anime depicts Otogi as the sole owner of Black Crown who blames Yugi for Pegasus' disappearance and duels him of his own accord.
- Defeat Means Friendship/Easily Forgiven:
- Even after all the crap he puts Jonouchi and Yugi through in the anime, Yugi and the gang forgives him, and it's helped when Dungeon Dice Monsters gets commissioned.
- In the manga, he grows to view Yugi as a Worthy Opponent during their battle, and is more than willing to become his friend after he realizes that his father's revenge is going too far and that he doesn't hate the Mutou family as much as his dad does. He even lends a helping hand to Yugi's friends when his father kidnaps Yugi to play the Devil's Board Game.
- Depending on the Writer: In the manga, he's a serious character with emotional problems stemming from daddy issues, comparable to Kaiba. In the anime, he's a narcissistic guy who somewhat revels in the attention he gets from girls and after he joins the gang, he forms a comedic duo with Honda for Shizuka's affections. He and Honda even almost get each other killed on Kaiba's blimp, over a girl.
- The Dragon: To his father, Mr. Clown, in the Dragons, Dice & Dungeons arc of the manga. The name Ryuuji literally means "dragon child."
- Drives Like Crazy: During the Doma Arc, as Haga, Ryuzaki, Jonouchi and Honda can attest.
- Dull Eyes of Unhappiness: Sports these when Yugi first encounters him in Black Clown's dark game room◊.
- Foil: Like Yugi, he's the youngest relative of a game shop owner and is an expert at games. Unlike Yugi, he is tall, handsome, but has a horrible relationship with his father and starts off with no friends other than his legion of fangirls, most of which also belonged to Bakura at one point. He is also a successful game designer at a young age, while Yugi only becomes a game designer some time after graduating high school.
- Four-Temperament Ensemble: Melancholic (in the manga).
- The Gambler:
- In the manga, Ryuji specializes in games that rely on percentages, for example, dice and card flips. He challenges Jonouchi and Yugi to Bar Bet games in the manga, games with fixed probability that are meant to trick his opponent in a gamble. He also created the luck-based board game of Dungeon Dice Monsters/Dragons, Dice & Dungeons.
- In the anime, he uses dice as weapons and runs a gambling deck focused on powering up his God Orgoth, which gets a Duel Monsters equivalent in the anime.
- Graceful Loser: After he loses to the regular Yugi in Dungeon Dice Monsters, he realizes he doesn't hate nor mind losing to Yugi at all. He was willing to hand the Millennium Puzzle over until his father intervenes.
- HeelFace Turn:
- In the manga, he ultimately betrays his father's rampage of revenge towards the Mutou family and becomes Yugi's friend instead.
- In the anime, he decides to stop being a jerk to the main group after losing to Dark Yugi and fully befriends the group after his DDM game gets commissioned by Pegasus's company.
- Improbable Weapon User: In the anime, he regularly tosses dice at people who try to catch them. In the manga, he flicked a dice at Jonouchi's face to provoke Dark Yugi into appearing◊.
- Insane Troll Logic: In the manga version of the DDM arc, Ryuji wanted to beat Yugi so his father can get revenge-by-proxy on Sugoroku, and ends up challenging him to a private game of Dungeon Dice Monsters. In the anime, however, it makes no sense. Ryuji wants to publicly humiliate Yugi and prove he's a cheater who never could have beaten Pegasus fairly. And he decides to do this by... challenging Yugi to a game that Ryuji himself invented. A game that's rather obscure and unheard of, and that Yugi has no idea how to play (and Ryuji doesn't explain it to him, either). If anything, Ryuji's victory would have just proven he was a cheater that couldn't win fairly. Not to mention that he wants his game to get more exposure, but it doesn't seem to occur to him that being an Arrogant Kung-Fu Guy about how good he is at it to the King of Games will probably turn off potential customers.
- Jerkass: In the anime, he starts off almost as bad as Kaiba was pre-Mind Crush. He gets over it when Yugi wins.
- Jerk with a Heart of Gold: Shown heavily during his arc in the manga. Despite making an ass out of himself when he first tries to humiliate Jonouchi with his fixed games and is seemingly determined to fulfill his father's dream of revenge and ruining Yugi's life, he's not that bad of a guy deep down and really only wants a worthy opponent in games. After slowly getting to like Yugi more and more throughout their game of DDD, when his father smashes the Millennium Puzzle, Ryuji looks at him with disgust and helps Yugi pick up the pieces before continuing their battle. His father, needless to say, was astonished by his kindness.
- King of Games: In the manga he was raised for the sole purpose of rivaling the Mutou family at gaming, and he's really good and knowledgeable about them. In-universe, he wants to gain the title "King of Games."
- Last-Name Basis: Except for his dad, everyone called him "Otogi".
- Love Triangle: With Honda over Shizuka in the anime.
- Oh, Crap!: Repeatedly in his DDM game with Yugi.
- Perpetual Frowner: In the manga, when he's not being a Smug Smiler during his initial games. It gets better when he joins the group, but not by much.
- Put on a Bus: In the manga, his character is suddenly dropped for unknown reasons during the Millennium World arc, only to reappear again to accompany his friends for the Ceremonial Battle.
- "The Reason You Suck" Speech: Very judgmental variations of this trope were used at Yugi throughout their Dungeon Dice Monsters match.
- Revisiting the Roots: The bar bet games he plays with Dark Yugi and Jonouchi at the beginning of the DDD arc in the manga is the first time in a while, and also the last, games to be played on the premises of Domino City High School like the earlier chapters.
- Ship Tease: With Honda and Shizuka. He gets some interaction with the former in the manga after his inital arc (Those Two Guys in the anime), and has a crush on the latter within the anime version.
- Sins of Our Fathers: His father lost a Shadow Game to Yugi's grandpa, and he wanted Otogi to beat Yugi in a game and take his Puzzle.
- Sixth Ranger: After the DDM arc, he joins with the main group somewhat.
- Smug Snake: In the dub anime during his Dungeon Dice Monsters game with Yugi, he's completely confident that Yugi is just a glorified cheater who doesn't stand a chance against him since he made the game and Yugi is an amateur who doesn't have any idea of proper strategy. Yugi's repeated use of Didn't See That Coming against him shakes him, but he brushes such instances off as luck. He mellows out once he loses.
- The Stoic: In the original manga.
- The Ugly Guy's Hot Daughter: Gender-inverted, Ryuji is the very good-looking son of his rather nightmarish-looking dad. However, it's shown that his father's face only became what it is today after losing to Sugoroku, so it could possibly be that his father used to be just as handsome as he is.
- Those Two Guys: With Honda/Tristan. Again, only in the anime.
- Took a Level in Kindness: After losing his Dungeon Dice Monsters match against Yugi, he considerably chills out.
- Tsundere: In the manga. It's not like I'm helping you because we're friends now or anything, d-don't get me wrong. I'm just tagging along to see where Yugi's strength comes from...that's all/I just owe you guys a favor, that's all!
- Weak, but Skilled: Ironically, while playing Dungeon Dice Monsters. Ryuji's strategy is basically to Zerg Rush Yugi, quickly expanding his territory with low-level monsters to box Yugi in and give him no room to summon his own monsters. Then he summons God Orgoth and pours all his resources into powering it up into a One-Man Army that can steamroll all of Yugi's monsters on its own. Little wonder Yugi was able to repeatedly outsmart him and eventually win.
- You're Nothing Without Your Phlebotinum: In the manga, he initially believes Yugi is nothing without the Millennium Puzzle giving him the expert gaming personality after his connection to Dark Yugi is cut off, and that he didn't deserved to be the King of Games because of it.
Tomoya Hanasaki (花咲 友也; Hanasaki Tomoya)
A friend of Yugi's who appeared in early manga chapters. He has an obsession with an American superhero called Zombire. He once dressed up as the superhero fought thugs that were hired by Hanasaki's dad so that his son could really think he was a hero. When the thugs turned on Hanasaki and his dad, Dark Yugi trapped the thugs in a maze of fire. After that he disappeared aside from a cameo in Death-T.
- Adapted Out: He doesn't appear in the Toei anime or the Duel Monsters anime.
- Adorkable: Hanasaki is a shy, timid kid who loves comic books, and in cosplay mode he becomes a Large Ham.
- The Bus Came Back: He appears in a few video games, including Monster Capsule GB, Dungeon Dice Monsters, and Reshef of Destruction.
- The Cameo: Makes an appearance in Yu-Gi-Oh! Reshef of Destruction, where he dresses up as Zombire to take out one of the Neo Ghouls by himself.
- Chuck Cunningham Syndrome: Appears for a few chapters early on in the manga before disappearing completely, with his last appearance at Death-T as he watches over Yugi's hospitalized grandpa.
- Clothes Make the Superman: Averted as Hanasaki thinks this trope is in play when the thugs were just acting.
- Dub Name Change: He's called "Lint Greendale" in the English version of the Dungeon Dice Monsters video game. Reshef also uses this name.
- Shrinking Violet: During his first appearances he's shy and quiet, like Yugi in the early chapters.
- Took a Level in Badass: Adaptational. In his brief appearance in Reshef of Destruction, he manages to take out one of the Neo Ghouls by himself, dressed as Zombire. Although he collapses afterwards and it's up to you to defeat the rest.
Miho Nosaka (野坂ミホ; Nosaka Miho)
- Voiced by: Yukana (JP)
A classmate of Yugi's who only shows up in the manga and the Toei anime. She is a one-chapter love interest for Honda in the manga and one of the main characters in the Toei anime. While she's a meek librarian in the manga, the anime has Miho as an outgoing girly girl with frequent crushes on boys who speaks in the third-person frequently.
- Adaptation Personality Change: In the manga, she is a shy girl who runs the school library. In the anime, she's a ditzy, girly social butterfly.
- Ascended Extra: Only appears as a girl Honda has a crush on in one chapter of the manga, but is a main character in the Toei anime. She doesn't show up at all in the second anime, though her name shows up on a list of disappearing Domino residents in Yu-Gi-Oh! GX.
- Berserk Button: Hurting or insulting her friends is usually enough to get Miho quite pissed.
- Beware the Nice Ones:
- Subverted in Toei's episode 11. She gets absolutely enraged when she learns Warashibe poisoned her friends with tainted water and brings Yugi along with her to challenge Warashibe to a Capsule Monsters game. Unfortunately, Miho has no idea how to play, and Yugi has to step in when she tries to leave after discovering Warashibe rigged the machine to give her weak monsters.
- In episode 19 of the Toei anime, Miho and Anzu find themselves in a popularity contest with an Alpha Bitch named Kaoruko. After Kaoruko insults Miho and Anzu, Miho comments that the contest is pretty much over how tight their skin is. This enrages Kaoruko because she's two years older than them, and the look on Miho's face says she knew exactly how much it would sting.
- Chuck Cunningham Syndrome: In the manga, she appears for one chapter as Honda's would-be love interest and never shows up again.
- Damsel in Distress: Gets kidnapped by Haiyama in the first anime series, and later has to be rescued from Warashibe when she's forced into playing Capsule Monster Chess with him.
- Dub Name Change: In the English Dungeon Dice Monsters game, her name is Melody.
- Fangirl: Towards Bakura in the Toei anime, as well as Kaiba and Ryuichi, until their true colors are shown.
- Girly Girl: In the Toei anime she's obsessed with jewelry, fashion, and boys.
- Hair Decorations: Wears a yellow ribbon with her ponytail. This led to her being nicknamed "Ribbon" by her classmates in the manga and Dungeon Dice Monsters game.
- Kawaiiko: In the first anime she loves girly things.
- Nightmare Fetishist: In the Toei anime she thinks mummies are cute, much to Anzu's confusion.
- Satellite Character: Despite being a main character in the Toei anime, Miho doesn't do much on her own or in manga-adapted arcs.
- Shrinking Violet: Manga-only, where she's a meek and kind librarian.
- Third-Person Person: Occasionally refers to herself in the third person in the first series anime.
- Tomboy and Girly Girl: The girly girl to Anzu's tomboy in the Toei anime.
- Two Girls to a Team: With Anzu in the first anime.
- You Gotta Have Blue Hair: Her hair appears to be blonde in the manga, but is purple in the Toei anime and Dungeon Dice Monsters game. The colored manga made her hair brown.
Tetsu Ushio (牛尾哲; Ushio Tetsu)
Ushio was the first villain of the manga and thus the first victim of Dark Yugi's Shadow Games. Ushio was a hall monitor of Domino High School and enforced its many rules, being feared even by its teachers. He offers a paid bully protection service to Yugi after he learns that he is being bullied by Jonouchi and Honda. Although Yugi refuses and denies that he has been bullied, Ushio beats up Jonouchi and Honda anyway and then demands that Yugi pay him a fee of 20,000 yen (about $200). After Yugi solves the Millennium Puzzle and becomes possessed by Dark Yugi for the first time, Dark Yugi called Ushio to meet him at the school during the night. Dark Yugi doubled the amount of money that Ushio had demanded, but insisted that they play a Shadow Game called "Money and Knife" for it. The game involved using Ushio's knife to stab more than one banknote each turn while they are on the player's hand, keeping whichever amount they manage to get and forfeiting the winnings if they stab their hands in the process. After a few turns, Ushio got greedy, and rather than risk not winning all the money in the game, he tried to attack Dark Yugi with the knife. In response to his cheating, Dark Yugi evaded the attack and inflicted the "Greed, Illusion of Avarice" Penalty Game on Ushio, making him believe he is being showered in money, which in actuality were just garbage and leaves.
In the Toei anime adaptation, he instead plays a game that involves reaching the top of a tower with playing cards, and Dark Yugi inflicts a Penalty Game in which Ushio is trapped in an illusion of water monsters eating him. He appears in the second anime as well, but only in a flashback. His ultimate fate is never shown, though the dub has him getting expelled from school.
For information on the 5D's version of the character, see the character sheet for Yu-Gi-Oh! 5D's.
- Asshole Victim: Although he poses as a person who stands for "justice" and can't stand bullying, he's actually a greedy jerk who is an even bigger bully. He beats up Jonouchi and Honda (in the first series anime, the latter is beaten up for no reason), extorts money from Yugi, and then tries to kill him for it. No sympathy is given when Dark Yugi gives him a Penalty Game and make a fool of himself.
- Big Ol' Eyebrows: His eyebrows are one of his most defining features.
- Bitch in Sheep's Clothing: He seems to genuinely want to protect his fellow students and Yugi, but all he really wants is to extort them for their money.
- The Bully: He claims to be fighting bullies, but is actually a much worse bully himself.
- Cheaters Never Prosper: He would have been better off if he didn't try to cheat during Dark Yugi's Shadow Game.
- Curbstomp Battle: He doesn't do that well in Dark Yugi's Shadow Game, so he tries to kill Yugi instead. It doesn't end well for him.
- Dirty Cop: Well, more like "dirty hall monitor". Funnily enough, the 5D's version of Ushio is a cop, but is a much better human being.
- Dick Dastardly Stops to Cheat: He would have gotten away with some money had he not been a greedy bastard.
- Disproportionate Retribution: While his Penalty Game in the manga had him see everything as money, the one he received in the Toei anime was to be devoured by monsters in an illusion, shattering his mind.
- Dub Name Change: In the English version of the Dungeon Dice Monsters video game, he's renamed to Demitrius the Bully. His 5D's incarnation is called Tetsu Trudge in the 4Kids dub.
- Greed: His "bodyguard service" takes advantage of Yugi's meekness in order to extort money from him, and Ushio's greed is what causes him to lose Dark Yugi's Knife and Money game.
- High Collar of Doom: The trench coat he wears in the manga when he meets Dark Yugi at night has a really high collar.
- Jerkass: One of the first in many of Dark Yugi's jerkass victims.
- Karma Houdini: In the second series anime, his Penalty Game is never shown so it's implied he gets off scot-free. The dub fixes this by adding a line where he got expelled.
- Kick the Dog: Not only does he beat up Jonouchi and Honda half-dead for merely teasing Yugi, he then proceeds to beat up Yugi as well.
- Recurring Character: Ushio appears or is mentioned in every Yu-Gi-Oh series so far.
- Red Armband of Leadership: As leader of the Morals Group, he sports one of these.
- Starter Villain: Seto Kaiba may have been Dark Yugi's first big villainous opponent and Yugi's greatest rival, but Ushio may have had an even bigger impact. He may have been little more than a thug (at least then), but after Yugi stood up to him after he was bullying Jonouchi and Honda, their opinion towards Yugi changed towards the better, leading to them becoming lifelong companions, and more importantly, Yugi completing the Millennium Puzzle and starting the chain of events that started the whole franchise.
- Villainous Breakdown: He has one during his battle with Dark Yugi, which ultimately causes him to lose the Shadow Game.
Sozoji (騒象寺, Sozoji)
Sozoji was a karaoke player who tried to get people to listen to his horrid singing. He forced Yugi Mutou and Tomoya Hanasaki to sell tickets to his "All Night Solo Live Show". When Yugi discovered that Hanasaki was also asked to sell tickets, out of kindness he offered to take charge of selling all the tickets, so only one of them would have to suffer. When Sozoji discovered the exchange, he beat up Hanasaki and forced Yugi to listen to his music at deafening volumes.
In reaction to this, Dark Yugi emerged and challenged him to a Shadow Game called the Silence Game. The game involved two Sound Pierrot toys from Yugi's grandfather's game shop, which reacted to sound - the first to make their toy react was the loser. Dark Yugi's headphone jack was balancing on a glass of water, and he excitedly anticipated its eventual fall into the water. However, the sound of his heartbeat caused him to lose the Shadow Game, and he was inflicted with a Penalty Game in which was forced to listen to his heartbeat at deafening volumes.
- Adapted Out: He doesn't appear in the Duel Monsters anime, but he doesn't appear in the Toei anime either.
- Asshole Victim: Might have been more sympathetic had he not beaten up Hanasaki and disturbed public peace.
- Believing Their Own Lies: It's hard to tell if he's deluded himself into thinking he's a good singer or if he knows he's bad and just doesn't care.
- Dreadful Musician: His singing's so bad it causes physical pain.
- Dub Name Change: In the English version of the Dungeon Dice Monsters video game, he's renamed to Fender Shrill.
- Giftedly Bad: He believes he's a singing masterpiece. No one agrees.
- Glass-Shattering Sound: Unlike a lot of the minor villains of the manga, he wasn't a murderer (attempted or actual), but his terrible singing might have killed Yugi anyway.
- Hoist by His Own Petard: The sole reason he lost the Silence game was because he took his own microphone that he set on maximum volume to blast out Yugi's eardrums with him and he didn't even notice he was holding it near his chest.
- Jerkass: The third jerkass of the series that Dark Yugi gets rid of.
- Mind Rape: Dark Yugi's "Heart Beat" Penalty Game probably drove him insane eventually if he didn't die from a heart attack.
- No Indoor Voice: His singing is loud, off-key, and has no volume control.
- Punny Name: His name in the English DDM video game, "Fender Shrill", refers to his terrible singing voice.
Kokurano (孤蔵乃; Kokurano)
- Voiced by: Shigeru Chiba (Toei anime)
Kokurano is the self-proclaimed psychic of Domino High School's Class 1-A. He became famous at school when he predicted a fellow student's house would catch fire, which came true 3 weeks later. In actuality, he had set the student's house on fire. After he tries to assault Anzu, Dark Yugi challenges him to a Shadow Game called Paper Crash where they had to pull papers from under a chloroform bottle without knocking it over.
In the Toei anime, the Shadow Game was changed to a more randomized game of catching chloroform bottles before they hit the floor. Kokurano tried to cheat, but failed anyway, and was knocked out for all the school to see.
- Abhorrent Admirer: For Anzu, particularly in the Toei anime.
- Adapted Out: Because the second anime adaptation skips over this chapter, he never appears there. Instead, the villain of the anime-only Burger World flashback was a perverted gym teacher with a camera, a Composite Character of Kokurano and Prisoner Number 777.
- Asshole Victim: The bad predictions he makes for his fellow students come true because he sees to it that it comes true, including burning down one of their houses. Also, he nearly killed Yugi by knocking bookshelves over him.
- Attempted Rape: He tried to rape Anzu after drugging her with chloroform before Dark Yugi shows up and challenges him to a Shadow Game.
- Believing Their Own Lies: His predictions are phony, but he's so loony that he actually believes he has psychic powers. This proves to be his downfall when he plays Paper Crash with Yugi. In that game, both players had to pull sheets of paper out from under a chloroform bottle, without letting it fall. Kokurano closed his eyes and tried to use his powers to "levitate" the bottle, but wound up knocking off the bottle of chloroform and faints.
- Chuunibyou: Kokurano's "powers" are delusional highs of egotism and grandeur that are said to be born of teenage hormones. He makes his prophecies come true by instigating crimes and spouting pretentious nonsense just so he can have some leeway.
- Dub Name Change: He's renamed to Fortuno in the English Dungeon Dice Monsters video game.
- Faux Affably Evil: Generally polite and well-spoken, but always haughty and vain.
- Girl Posse: Tons of schoolgirls in the manga and Toei anime are his fans, particularly in the anime.
- Jerkass: He's completely obnoxious and full of himself.
- Karma Houdini: He's guilty of attempted murder, arson, and attempted rape. His only punishment is to get knocked out and exposed as a fraud, while others got much worse punishments for lesser crimes.
- Little People Are Surreal: He tries to invoke this.
- Phony Psychic: Has plenty of fortunes prepared in his cape to make it seem as if he made a prophecy beforehand, and makes sure the bad prophecies come true himself, such as burning down a person's house after predicting his house would catch on fire. He especially has no problems doing the latter if the person pisses him off. And in Anzu's case, he predicted she'd meet a wonderful man soon, intending to become said man.
- Stalker with a Crush: He tries to win Anzu despite her disinterest, later attempting to rape her.
- Younger Than They Look: He has long gray hair in spite of his being a high school student.
Goro Inogashira (猪頭吾郎, Inogashira Gorou)
Goro was part of a class that served Hiroshima-style okonomiyaki for the Domino High School festival and was the Senior Class D festival committee president. When Anzu Mazaki's class won his class's favored spot at the festival in a raffle drawing, he ordered his classmate's to tear down the Anzu's class' booth and seized the spot. However, Dark Yugi won it back by defeating Goro in a Shadow Game called "Griddle Ice Hockey".
- Absurdly Powerful Student Council: Due to his influence and senority, the school staff didn't do a thing about him stealing a festival spot, leading our then Sociopathic Hero Dark Yugi to solve the problem by committing possible murder.
- Adapted Out: He neither appears in the first series anime nor the second series anime.
- Asshole Victim: Didn't give an absolute flinging care to whether if Yugi and the group were in the way, let alone in the booth they were ramming into pieces with. Yugi even got a stay in the school infirmary being trampled near to death trying to stop them. Given that he was a senior too, Dark Yugi gives him a little taste of what it's like to be on the grill and to let him know that he can't push around to get what he wants.
- The Bully: Considering Domino High's penchant for being a hive of bullies at this point and probably only second to Rintama, Goro takes on the role of a bancho gone bad and uses both his seniority and bulk to throw his weight around probably like Ushio.
- Continuity Cameo: His name makes a cameo appearance in GX as one of Trueman's victims.
- Dub Name Change: Named "Kreiger" in the DDM game.
- Expy: He existed way before then, but he resembles the cheerleader dudes in Osu! Tatakae! Ouendan.
- Honor-Related Abuse: As indicated of his very Japanese bancho looking appearance and name and as a bully, he essentially demands any underclassmen to yield their position when he demands so, or else.
- Kick the Son of a Bitch: He stole a stand to sell delicious food and beat up a few people. Dark Yugi punishes him by blowing him up. Not only did his class destroy Yugi and his classmates' hardwork, they trample normal Yugi. And Goro knocked out Jonouchi while he was stuck in a life-sized Pop-Up Pirate barrel. Though this would seem as typical as normal villains as bullies like Goro would throw out, it also doesn't help that his appearance is supposed to imply he is a bancho, and pulling this off anywhere else outside of Yu-Gi-Oh's setting would likely see him get his face smashed in by someone more honorable and virtuous of his like.
- Knight of Cerebus: Ushio was Dark Yugi's first opponent, sure, but Goro was the first one that actually briefly broke Dark Yugi's poker face with his strong arm during the game and forced him to think outside the box rather than breeze through.
- Sore Loser: You could have just found another stand, or just deal with what you got like a real man would do there, Goro.
- Student Council President: The festival committee's president for his class.
- Supreme Chef: Apparently his okonomiyaki is that good.
Kujirada (鯨田, Kujirada)
- Voiced by: Shouzou Iizuka (Toei anime)
Kujirada was one of Yugi's more snobbish classmates. When Digital Pets became a fad at Domino High School, Kujirada starts causing trouble with his.
- Adaptational Heroism: In the Toei anime, he first appears as he does in the manga, but it turns out he was being bullied by Haiyama, who is the real antagonist of the Digital Pet story there.
- Demonic Dummy: His Hidden Pet is basically this.
- Dub Name Change: Named "Beluga" in the DDM game.
- Early Installment Weirdness: Kujirada's Digital Pet is one of the stranger aspects of the first dozen chapters, it's not even related to the Shadow Game magic from Ancient Egypt... it's just a demonic modern-day toy.
- Fat Bastard: Both Kujirada and his Digital Pet.
- Mind Control: Experiences this one night where, after being tired of regular pet food, his Digital Pet basically commands him to feed it other pets.He's only freed from the pet's mind control after Yugi's U-2 beats the snot out of it.
- My Little Panzer: The Digital Pets sure seems like a fun thing for children. Kujirada's pet and the other pets seem to have a mind of their own. Possible Digimon reference?
- Oddball in the Series: Until the Toei anime came along, he or rather his digital pet, is one of the few people who isn't subjected by a Shadow Game pre-Character Development of Dark Yugi (nor getting involved either). U-2 does evolve, bearing the likeness of Dark Yugi and deletes Kujirada's evil Fat Bastard of a pet. Unless you want to be technical, Kujurada's pet did suffer a "Penalty Game" involving deletion.
- Serious Business: Digital Pets are a matter of life or death to him.
- Smug Snake: He's so confident his Digital pet is unbeatable he doesn't register Yugi's as a threat at all, until it evolves.
- Troublemaking New Pet: Having an ultra rare Digital Pet isn't as cool as it seems. You might lose sleep over it.
Koji "the Spider" Nagumo (名蜘蛛 コージ; Nagumo Kouji)
- Voiced by: Shin Tomita (Japanese), Matthew Charles (English)
Nagumo is a gamer with interest in a variety of games, ranging from Monster Fighter to Duel Monsters/Magic & Wizards. However, he has no real respect for games. Nagumo engages in gaming to make money and often focuses on the potential resale value of desirable collectibles, including Monster Fighter figures and rare cards such as Seto Kaiba's Obelisk.
Nagumo, at heart, is merely a bully who relies on his physical strength to win games when he is in danger of losing, rather than accepting defeat gracefully, and uses his hobbies to lure in potential victims to extort with his strength.
- Adapted Out: He doesn't appear in the Toei anime.
- Aesop Amnesia: He apparently didn't learn a thing from his Monster Fighter Shadow Game with Dark Yugi, and harasses a duelist for his rare cards during Battle City a dozen volumes later. It doesn't end well for him when he runs into Kaiba and his God Card.
- Arachnid Appearance and Attire: He's not called Koji "the Spider" Nagumo for nothing. He even lures in weak gamers to extort, like a spider does its prey.
- Asshole Victim: He's a jerk of the highest caliber, so both of his punishments are well-deserved.
- The Bus Came Back: He's an early villain that suffered a Penalty Game that returns with his sanity intact during the Battle City arc, only to get even more traumatized by Seto Kaiba and his Obelisk.
- The Cameo: He makes appearance as an NPC in Reshef of Destruction. He also appears in the Pyramid of Light movie, and his name appears in GX as one of Trueman's victims.
- The Collector: He collects Monster Fighter figurines and rare Duel Monsters cards for profit.
- Dub Name Change: The English DDM video game changes his name to Stringer.
- Jerkass: He was enough of a dick that Yugi lost his cool and sicced his alter-ego on the guy.
- Mind Rape: Dark Yugi raised the level of his Shadow Game against Nagumo, making the players feel the pain of their monsters. Towards the end of the game, Nagumo's Wild Spider horrifyingly turned into a little Nagumo/spider hybrid, and received a final blow to his face.
- Oh, Crap!: When he reappears in the Battle City arc, he has this reaction when Kaiba sics Obelisk on him. His face is stuck with a horrific expression afterwards, obviously traumatized.
- Sore Loser: He resorts to violence when games don't go his way.
- Unsportsmanlike Gloating: He does this to the normal Yugi.
Imori (井守 ; Imori)
- Voiced by: Megumi Urawa (Toei anime)
Imori was one of Yugi's classmates at Domino High School. At first seemingly withdrawn and somewhat shy, Imori is then revealed to be an anti-social and selfishly vindictive human being. In the Toei anime he is nicer, being a victim of bullying and the corrupting power of the Dragon Block game.
Imori discovered the secret of Yugi's Millennium Puzzle and decided to usurp Yugi's position as the guardian of darkness by challenging Yugi to a game of Dragon Cards, a Chinese Shadow Game that his grandfather found in Manchuria during World War II. The loser of the game would have their soul stolen by its soul-eating jar and devoured by 25 dragons.
- Adapted Out: In the second anime he doesn't appear.
- Adaptational Heroism: In the Toei anime, he's a genuinely decent human being who is under the evil influence of the Dragon Blocks.
- Appeal to Force: Imori immediately unties and in turn unseals the game when he confronts Yugi. Doing this demands that a game must be played, or the land which the game was unsealed will forever suffer disaster and misfortune.
- Asshole Victim: In the manga, he's killed. His Toei anime counterpart survives through the good half of his soul.
- The Cameo: His name makes a cameo in GX as one of Trueman's victims.
- Dub Name Change: The English version of the Dungeon Dice Monsters game calls him Damien Draco.
- Early Installment Weirdness: The Dragon Cards are a Chinese Shadow Game that bring disaster to the land without even playing a game, require a game to be played to calm the dragons' wrath, and are never brought up again despite the danger they pose.
- Soul Jar: Lose at Dragon Cards and your soul goes into the soul-eating jar, which will devour your soul within three months. Imori's Penalty Game is being trapped in the jar.
- Spared by the Adaptation: In the manga, Imori's soul is devoured by the soul-eating jar. In the Toei anime, the good half of his soul lives on while his evil half is eaten.
- What Happened to the Mouse?: Dragon Card is never brought up after its sole appearance, and Yami Yugi can only hope no one else finds it and unseals the dragons. Likely downplayed, as considering how Yugi has it in his hands by this point, gaming runs in the family, and Suguroku likely stashes it away somewhere far deep in Kame Game Shop. The Toei anime makes this worse when they hide it in Imori's house.
Nezumi (ネズミ; Nezumi)
Nezumi is a buck-toothed boy who uses a sob story about getting hit by yo-yos in a robbery to lure Yugi Mutou and Katsuya Jonouchi to one of their previous foes, Hirutani, who is out for payback.
- Adapted Out: Neither anime features him.
- Bitch in Sheep's Clothing: Yugi and Jonouchi meet Nezumi at school. Nezumi claims that a gang of bullies attacked him and that he needed help in dealing with them. In fact Nezumi was ordered by Hirutani, to have Jonouchi and Yugi lured to the abandoned warehouse so that Jonouchi could be forced to re-join Hirutani's gang.
- Dirty Coward: He cuts and runs when the ruse is revealed.
- Dub Name Change: The English version of the Dungeon Dice Monsters video game called him "Nibbles."
- Meaningful Name: Both his name and his English video game name references his face looking like a mouse (nezumi means mouse in Japanese and "nibbles" is self-explanatory), and to street slang: he essentially is an untrustworthy double crossing skeeze who betrays to whomever he follows or are ordered to follow.
Bakura and Otogi's Fangirls
Three female fans of Ryo Bakura and/or Ryuji Otogi, depending on the medium. In the manga and Toei anime they are Bakura's fangirls and offer him a tour of the school, to which he declines, and later fawn over Otogi and his dice tricks. In the anime they are exclusively Otogi's fangirls and dress up as cheerleaders, cheering him on in his duels against Jonouchi and Yugi. A similar group of girls appears in Yu Gi Oh The Darkside Of Dimensions, fawning over Bakura once more.
- Adaptational Villainy: In the anime, besides cheering Otogi on they boo and harass Jonouchi and Yugi.
- The Cheerleader: In the anime they are this to Otogi, and anti-cheerleaders to Jonouchi and Yugi.
- The Ditz: One fangirl asked Kokurano how to avoid dying, to which he replied as long as she kept living she wouldn't die. The Toei anime made this worse by having her ask how long she'd stay beautiful, oblivious to her appearance.
- Double Standard: Abuse, Female on Male: Their interactions with Jonouchi in the anime, where they repeatedly pummel and demean him, are played as comic relief.
- Early-Bird Cameo: In the manga, one of the fangirls was first seen very early on, fawning over Kokurano's predictions.
- Fangirl: They're huge fans of Bakura and Otogi.
- Gonk: One of them has a rather cringe-worthy design. She's slightly less gonkish in the second-series anime.
- No Name Given: None of them are named.
Ms. Chono ((蝶野先生; Chouno-sensei)
- Voiced by: Masako Katsuki (Toei anime)
A teacher at Domino High who wears so much makeup it's like a mask. She's known for being beautiful and very cruel, expelling students on technicalities and purposely dating men to break up with them.
She ran afoul of Dark Yugi when she tormented Yugi, Jounouchi, and Honda by reading a love letter Honda had written to Miho Nosaka out loud, and threatened to expel whoever had written it. As punishment, her makeup turned into puzzle pieces and cracked off of her face, revealing her true, hideous face. She is one of the few female opponents Dark Yugi faces. In the Toei anime, her role is expanded, with her Penalty Game being altered to turn her into an old hag and causing her makeup to crack whenever she tries to bend the rules.
- Adapted Out: She doesn't feature in the second anime.
- Adaptation Dye-Job: Has blonde hair in the manga, but has red hair in the first anime adaptation and brown hair in the Dungeon Dice Monsters game. The digital coloring of the manga retained her blonde hair.
- Adaptational Villainy: Her manga counterpart is by no means a good person, and the Toei anime managed to make her worse. Manga!Chono was only interested in humiliation, but in the Toei series she's a sadistic control freak willing to go to extreme lengths to break Anzu's spirit just for questioning her authority.
- A God Am I: She refers to herself as the goddess of the classroom at one point.
- Ascended Extra: An odd example in the Toei anime. Her role as an antagonist is expanded to fill out an entire episode whereas her appearance in the manga was limited to only one chapter that took place almost entirely in a classroom. While she disappears altogether in the manga, she remains as a minor character in the anime where she's still teaching at Domino High and still somewhat strict, but she no longer antagonizes Yugi or his friends.
- Beauty Mark: Wears one below her left eye.
- Dub Name Change: In the DDM video game her name is Miss Lynn Madusa.
- Hope Crusher: Ms. Chono lives to crush the hearts of men, and delights in expelling students on technicalities.
- Hot Teacher: The students note she's beautiful, but she wears too much makeup.
- Hypocrite: The Toei anime makes it clear that, unless she's the one who stands to gain from enforcing them, the rules mean squat to her.
- Identical Stranger: She looks nearly identical to Mai, which is likely why the Toei anime and video games changed her hair color to differentiate them more.
- Lazy Bum: She talks about how school rules need to be very strict, and those who break them should be punished extremely harshly, but she never gives a credible reason why. When she senses the vice principal doesn't immediately agree with her, she flirts with him in order to get him flustered enough to change his mind but still without giving a decent explanation. Her laziness comes from her inability to properly justify her actions, or even make the barest effort to justify them, relying on her looks to get people to agree with her.
- Makeup Is Evil: She wears so much of it it's like a mask. In the Toei anime, after her Penalty Game with Yugi, any time she acts cruel or strict her makeup will loudly and noticeably crack like an eggshell.
- Not Good with Rejection: She'll eagerly go on matchmaking dates for the joy of stringing men along and then breaking their hearts, but God help you if you dump her first. In the manga and Toei anime, when reminded about being dumped on her last date, she vents by trashing one of the school bathrooms.
- Rage Against the Reflection: She breaks a mirror out of rage at being stood up.
- Sadist Teacher: She delights in expelling students on technicalities and tormenting them by revealing their secrets.
- Screw the Rules, I Make Them!: She's all about enforcing strict rules, but she's more than willing to use delinquent students to do her dirty work by offering to expunge their records. Although she does threaten them with expulsion if they misbehave again.
- The Smurfette Principle: In the manga, she's Dark Yugi's only female opponent to receive a Penalty Game.
- Stepford Smiler: No matter how angry or vindictive she is on the inside, on the outside she's all smiles.
- Troll: In the Toei anime, she gives Anzu the idea of collecting signatures to petition the school's strict policies. Chono then discreetly does everything she can to make sure Anzu won't get any help from her classmates, spreading rumors that those who sign get targeted by the rest of the teachers, manipulating the male teachers into believing Anzu's a delinquent and shaming her in their classes, and getting delinquents to harass Anzu in exchange for expunging her records. Chono also takes the time to patronize Anzu's failing efforts, and when Jonouchi gets in trouble for defending Anzu, Chono says "Well, the cause of all this was you, wasn't it?"
- Uncanny Valley Makeup: She slathers on so much makeup it's like a mask.
- The Vamp: In the Toei anime, she flirts with the vice principal in order to sway him into making the rules stricter, and later gets some of the male teachers on her side by feigning innocence, claiming Anzu was acting completely unreasonable.
- We Will Meet Again: After her Penalty Game, Ms. Chono swears revenge. She never gets it.
- Your Makeup Is Running: When she drops her cheery facade it makes her makeup run, and in the Toei anime she has trouble keeping it on after her Penalty Game.
Guidance Counselor Tsuruoka
- "Worthless, back-talking failures like you three will never have rights! We educators can do anything to you dropouts, and be forgiven later!"
Another one-chapter-only villain in the manga, and the first one after Death-T (meaning also that he's one of the last).
A teacher who humiliates Yugi, Jounouchi, and Honda for their bad grades in front of the rest of their class and confiscates a key chain game from Yugi (said key chain being a gift from Anzu). Just as he's about to crush it, the Other Yugi appears and challenges him to a game. If Yugi and co. can find the keychain somewhere in the school, they can get it back; otherwise, the three will get suspended and the key chain will be smashed.
- Adapted Out: Neither anime features him.
- Bald of Evil: Revealed after he tried to cheat by hiding the keychain under his wig, which completely backfired on him when the key chain started to ring.
- Cheaters Never Prosper: He hides the key chain on his person and stays in a teachers-only place, knowing that students aren't allowed in there.
- Dub Name Change: The DDM game named him Anton Periwig.
- Sadist Teacher: Not to the extent of Ms. Chono, but after seeing Yugi and co. were playing a completely harmless game of bingo out of the test rankings, he publicly states their abysmal test results, mocks them about it, and confiscates Yugi's key chain to crush it. And then there's the quote above. He's also quite eager to get three students suspended.
Mr. Karita (刈田先生; Karita-sensei)
Villager D (村人D; Murabito D)
Mr. Karita is Domino High School's physical education teacher, who is widely hated by the students for his brutal and oppressive ways. He harassed Ryo Bakura on his first day at Domino High School. When Dark Bakura, Ryo's evil alter-ego within the Millennium Ring, emerged to avenge his host, he challenged Karita to a Shadow Game in which Karita lost. After suffering a Penalty Game called "Mind Doll", Karita's soul was trapped in a lead figurine and became Villager D within the Monster World tabletop role-playing game. Afterward he was restored to normal, with no memory of the incident.
- Adaptational Villainy: In the Toei anime, rather than threaten to cut Bakura's hair, he teased him about his friends from other schools going into comas and warned Yugi and his friends away from him.
- Asshole Victim: He's a bully of a teacher who gets trapped in a tabletop role-playing game. Though he's saved in the end.
- The Cameo: Appears in Yu-Gi-Oh! The Dark Side of Dimensions.
- Dub Name Change: The DDM game named him Mr. Titus.
- Generic Name: As Villager D.
- Jerkass: Even though a villain gives him a Penalty Game, he deserved it for mocking Ryou.
- Jerk Jock: He's a rude, nasty phys-ed teacher.
- Non-Player Character: Of Dark Bakura's Monster World role-playing game
- Sadistic Choice: Was forced by Dark Bakura into a choice between the role of Villager D in his games for all eternity or death. Karita chose the former, but he's eventually saved.
- Welcome to Corneria: Trying to avert his generic dialogue gets him into trouble with Bakura.
- Your Soul Is Mine: Dark Bakura traps his soul in a lead miniature RPG figurine.
