Yugi Mutou – a cowardly boy who requires Atem to duel for him.
Seto Kaiba – an atheist who wants to forget the past. He has to SEE something in order to BELIEVE in it, and sometimes when something is right in front of his face, he still doesn’t believe it.
Maximillian Pegasus – the disillusioned “creator” of Duel Monsters. He cheats by using a Millenium Eye in dueling, which allows him to see the opponent’s hand and plan his moves accordingly. Wants to use the Millenium Items to bring his wife back from the dead.
Cecilia – Pegasus’ dead wife. If it were not for her early departure from the world, there would be no game of Duel Monsters. Pegasus has multiple paintings of her that he stares at all day. She would also have fooled around with Bakura had she lived, for there are hints of this in the final DM season.
Joey Wheeler – a boy with a Brooklyn accent whose cards all deal with gamling of some sort. He’s so bad a duelist that Seto Kaiba had a robotic monkey named after him.
Tristan – a tough guy like Joey, not a duelist. He actually just wants Joey’s sister.
Tea Gardner – a girl obsessed with friendship who wants to be a dancer one day. She’s in love with a 5000-year-old Pharoah.
Atem – a man who looks like Yugi and lives in Yugi’s body. He is actually three and a half feet taller than Yugi. Yugi forces him to duel in his stead. He almost always wins. Seto Kaiba would be jealous of him if he knew that Atem forgot everything about his past, when he first inhabited Yugi’s body. Until we, the viewers, knew his real name, we called him “Yami.”
Weevil Underwood – a c***roach disguised as a boy. He’s secretly in love with Tea.
Rex Raptor – a boy who thinks that dinosaurs and dragons are the same thing. He begs Mai to kiss him, but she refuses.
Mai Valentine – Materialistic and conceited, her name is a play on the words “My Valentine.” But she’s not meant for Yugi. Fans have said that Mai and Joey slept together and produced Alexis Rhodes, which would be impossible unless there was a time hole. There is also a theory that she has a crush on Harpie Lady, since she never takes it out of her deck. I mean, if you don’t have a crush on a monster, you won’t use it as a crutch.
Maako Tsunami – His Christian name really only has one ‘a,’ but it looks better this way. He is obsessed with WATER monsters, probably because his father was molested by an octopus.
Panik – a man who thinks that shielding his monsters will help him win. Tries to burn Yugi and his friends when he loses, but the Millenium Shield protects them, proving that Atem is a Gary Stu.
Para and Dox – These labyrinth lovers have names that together create the word “paradox.” Although it is the lexicographer’s personal opinion that “Oxy” and “Moron” would’ve suited them better. They don’t even know that Red Eyes Black Dragon can FLY! How stupid can you get? But this is when we are introduced to tag dueling, though it is a very strange version of tag dueling. This is also where one of the most-often used idea takes place. The only thing seen more often in any kind of story is the question, “What walks on four legs in the morning, two legs in the afternoon, and three legs at night?” Para and Dox also make an appearance in the GX era. They almost defeat Jaden and Syrus. If they had won, Jaden would’ve got suspended and GX might’ve been ACTUALLY WATCHABLE.
Bandit Keith – a thief who plays Machine-monsters, which are unaffected by Spellcasters. His next card is always up his sleeve.
Bonz – a Zombie-lover who secretly reads Twilight when his boss is not watching. He doesn’t consume anything that doesn’t have pumpkins in it. He drinks pumpkin juice, eats pumpkin pie for desert, snacks on pumpkin seeds, and even eats pumpkin sandwiches. His favorite move is “Deadly Zombie Breath!” (He has halitosis.)
Mokuba Kaiba – Seto’s little brother. He doesn’t know how to duel, though we do catch him pretending he does once. Seto gives him a card he always admired when Seto decides he’ll quit dueling. The card is not shown on-screen, but there is a suspicion among fans that the card is Shapesnatch.
Yugi’s Grandfather – a retired architect who now owns a game shop, which is cleverly called Game Shop. He trains Joey for combat, in other words, teaches him how to duel. He had the fourth Blue Eyes White Dragon, given to him by Arthur Hawkins, when Solomon Mutou gave him the last drink from his canteen. Yugi’s grandfather would give up dueling to own a TV that is 10 feet by 10 feet. He also goes goo-goo eyes for girls Yugi’s age, except Tea, whom everybody seems to be sexually oblivious too.
Arthur Hawkins – gave Solomon his Blue Eyes. He really only gave it to him because he thought Solomon would die from lack of water, before someone came to save them, hoping that Solomon would think him a great friend in whatever place he ended up after death. When Solomon lived through that trauma, he was in shock, which is why he did not visit Mr. Mutou for another twenty years.
Rebecca Hawkins – Arthur’s little brat of a daughter. At first she has an annoying teddy bear, but later she comes back with glasses. She is a ten-year-old attending college. Yugi gave her his Ties of Friendship Spell card, and ever since she’s been in love with him. Most likely, Yugi married her and Mindy is their offspring.
Johnny Stepps – a guy who wants to date Tea if he beats he in a dancing match. He cheats but she still wins. Then he duels Atem; if he wins, he gets to date Tea. But Johnny quits when he finds out his opponent is Yugi Mutou. It is partly because of this guy that Tea falls in love with Atem
The Big Five – a sneaky group of corporate junkies who think that Five God Dragon will destroy Kaiba and get them in control of the company. First they attempt this through a virtual game, then they try this through Noah’s virtual world. They fail both times, and it’s all Atem’s fault. They have sworn to go back 5000 years and murder Atem so that in the present time they can conquer Seto once and for all.
Duke Devlin – a guy who thinks that the creator of a game is undefeatable. To him, it would be impossible for Satoshi Tajiri to lose a Pokemon battle. He fights with Tristan for the hand of Joey’s sister. He can’t accept the fact that any girl in the world will have him except Serenity. Also obsessed with dice.
Serenity Wheeler – a girl who almost went blind but was saved by the prize money that Yugi won and lent to Joey. She and Tea have kindred spirits, and the only reason Tristan hits on Serenity and not Tea is that he sees Tea every day, and Serenity is a new face.
Espa Roba – a fake psychic in love with Jinzo, which all Psychic monsters are modeled after. He had his little brothers use binoculars to see what his opponent’s cards were. Mr. Armstrong in 2021 copied this tactic, only with security cameras. It’s possible that fifteen-year-old Espa later became one of Mr. Armstrong’s friends, when he’d be, oh…forty-three.
Yami Marik – the evil side of Marik Ishtar, who wants to take over the world with the Egyptian God cards. He uses the power of mind control via the Millenium Rod, though he stole the rod from Seto Kaiba. Thanks to this dude, we get to see Yugi actually duel…against his best friend, Joey. When Yami Marik ends up dueling Joey himself, Joey wins, except that he faints because he lacks energy. Yami Marik deserved his second visit to the Shadow Realm.
Marik Ishtar – a good guy. He’s obsessed with motorcycles, though.
Ishizu Ishtar – a hot Egyptian girl who can see the future, except when it involves the reincarnated spirits that are in Yugi and Seto.
Shadi – a pimp who Pegasus met when he visited Egypt, and who stupidly showed him the Egyptian God monsters, whom he was unable to control. Can steal into your mind with a Millenium Key, so you better watch out. The police would love have to him for work for them.
Odion – a man who pretends to be Marik to fool Yugi and his friends. He rarely uses monsters, and never Normal Summons when he does use them. Instead he uses Trap Monsters, which are just as, if nor more, effective. (He also never lost a duel till he battled Joey Wheeler. Maybe Joey was his first opponent?)
Strings – a mime also known as “the Quiet One.” He can’t speak for himself, but Marik’s mind control allows him to speak through him. Does something that would be illegal in the real game, by summoning Slime Tokens and brining out Revival Jam to block all of Yugi’s—excuse me, Atem’s—attacks. Strings then summons Slifer, which gains more ATK for each card in your hand. Atem uses Strings own tactic against him. Due to Card of Safe Return, Strings must keep drawing cards each time Revival Jam is summoned. And since Revival Jam can’t disappear from the Field, and Slifer’s Second Mouth attack keeps on going and going and going (like the Energizer bunny), and since Revival Jam is on Atem’s side of the Field thanks to Brain Control, Atem wins. This is the first and only time in the entire series that a duelist loses because he decked out.
Arkana – a duelist in love with some girl named Catherine Eanrshaw/Linton/Heathcliff. He has a strange voice that many viewers can’t stand. His Dark Magician card looks weird. The duel Atem had with this guy introduced use to Dark Magician Girl.
Lumis and Umbra – A couple of masked freaks who think there’s an “I” in “team.” All of the monsters they summon wear masks, and all of the Spells and Traps they play either have “Mask” in their card name or feature masks in their artwork. I wonder if they read “The Haunted Mask” by R.L. Stine.
Gozoboro Kaiba – this is a grotesque spelling of his name, but he is a grotesque character, so I don’t care. When he controlled KaibaCorp, it was a place that produced weapons and machinery for war. He adopted Mokuba and Seto after Seto defeated him in a chess match. He might not have agreed to it either if his own son hadn’t perished from some terminal illness. Seto turns KC into a game-centered company after Gozoboro is taken care of.
Noah Kaiba – the only son of Gozoboro. When his body was in danger of deteriorating, Noah’s father built him a virtual world which was supposed to resemble the real one. Then his soul was put in said world. Noah tweaked it a bit a long time later, and a KC blimp got caught in the vortex. In Noah’s revamped virtual world, you dueled with Deck Masters, which you could bring into the game, but when destroyed means you lose, even if you have Life Points remaining. Noah, like all Yugioh villains, turns out to be a nice guy. He saves Yugi and co. from Gozoboro’s wrath. Mokuba wishes that Noah could come back to life and be a real brother to him.
Roland – one of the “black suits” that works for KaibaCorp. He obeys everything Seto orders him to, for fear of losing his job.
Dartz – a several-millenia year-old man, who has white hair and worships the Seal of Orichalcos. He has several people persuaded to work for him. Or controlled. Take your pick.
Seal of Orichalcos – This thing is so important that I’ll treat it as a character. Yes, I realize I skipped the Millenium Items, but there’s not much to say about them. This Seal is a uberly-broken card that allows you to summon up to ten monsters (no point in that), raises all your monster’s ATK by 500, is impossible to destroy, and sends the loses soul to oblivion. I guess it’s better than the Shadow Realm.
Dark Magician Girl – the “queen” of the place known as the Dominion of the Beasts, where all of the Duel Monsters reside. She has a crush on Syrus Truesdale.
Raphael – a man named after a famous artist, but who probably never drew a damn thing in his life. He is very muscular, and he uses Guardian cards, especially a broken card called Guardian the Eatos. He was washed away on an island for many years. He is also one of the very few people to EVER defeat Yugi in a duel. Oops, I meant to say Atem.
Valon – a young man in love with Mai Valentine. His cards are actual armor that goes on his body. Go figure.
Zigfried Lloyd – This is a pseudonym and a play on the name, “Sigmund Freud.” This man has pink hair, and duels with Valkyries. He beat both Weevil and Rex in one move. But he ends up losing to Kaiba when Kaiba plays Chaos Emperor Dragon – Envoy of the End. Fans believe that this duel is why Chaos Emperor Dragon is banned in the anime. Sought revenge with Kaiba in the KC Grand Prix, and when it’s all over he cries and asks for forgiveness! Talk about sappy.
Leon von Shroeder – Zigfried’s little brother. Uses fairy tale creatures only. He kisses his Cinderella card at night. Zigfried tries to get him to cheat, by playing a card that doesn’t exist and shouldn’t work on the Duel Disk, but does because Zigfried is a computer whiz and knows how to mess around with stuff.
Uotum Apdnarg – Grandpa Mutou’s name spelled backwards. He used when he entered the Grand Prix, and his first opponent was Joey Wheeler. I only mention him because this is one of the few duels we actually witnessed in the Grand Prix. There was also a doctor, a simian dude, and several other characters, whose duels they just didn’t show.
Vivian – a girl who has a crush on Yugi. She is closer to his age than Rebecca is, but she’s more like a Romilda Vane than any other character in the series. Pretty cute, too, but not Yugi’s type.
Yami Bakura – This guy is the most evil in the entire series. First he just wants the Millenium Items, then he wants the Egyptian Gods, then he decides to meddle with Atem’s past and sends our heroes back to Egypt. Almost becomes Pharaoh himself, by tricking Atem in the past. A pretty good duelist; some fans are upset that not all of his cards are in the TCG yet.
GX era:
Jaden Yuki – an idiot who doesn’t know that “Sayonara” is Japanese, and he IS Japanese.
Syrus Truesdale – Jaden’s best friend in the beginning of the series. His mother wants to hump him, which is why she always tells him that he’s handsomer than his brother. Dark Magician Girl and Thunder Nyan-Nyan fight over him.
Chumley Huffington – a problematic boy who looks like a koala. Unlike Raphael, he CAN draw. Syrus complained once about him putting Dark Magician next to Dark Magician Girl. He went to work for Industrial Illusions. Jaden had him draw the Neos cards when Jaden created them.
Zane Truesdale – the only reason girls watched Yugioh GX. His mother must be blind to call Syrus handsomer than him. Though it must be said that Dark Magician Girl doesn’t have a crush on Zane. He duels pretty well, but it utterly dependent on Cyber Dragon.
Alexis Rhodes – the only reason boys watched Yugioh GX. Probably the cutest girl in Yugioh ever. Oh, and she can duel, too.
Dr. Vellian Crowler – a man who would rather be called “Mrs.” than “Mr.” His voice even sounds like a girl’s. He uses Ancient Gear monsters, and has a crush on a vampire lady named Bella Swan.
Chazz Princeton – Jaden’s rival. He starts off being an Obelisk Blue, but because he’s so stupid he gets kicked out of school, goes to North Academy and wins with a random deck. He duels against Jaden again, and this time he returns to Duel Academy as a Slifer Red. Due to his defeat, he suffers brain damage and thinks that there’s a possibility Alexis will like him.
Blair Finnagan – a girl who dresses like a boy and has a crush on Zane, until she duels Jaden and he beats her. Then she gets a crush on him. She comes back to the school later, and makes a cameo appearance in 5D’s.
Dmitri – a guy who can’t find his own dueling style, and so he copies others. He even DRESSES like the person whose deck he is copying, even if it’s a girl. Dressed as Mai Valentine, he duels Alexis Rhodes and loses. The real Mai wouldn’t have lost. After this duel, he dresses as Alexis, who tells him to get lost. (Behind the scenes, Mindy sneaks up on Dmitri-dressed-as-Alexis and gives him a big kiss. She is disgusted when she finds out it’s a boy. Alexis doesn’t find out about it.)
Bastian Misawa – a scientist-in-training, he likes playing cards that deal with Chemistry. However, he can’t get a girl. Supposedly he’d rather have a teddy bear named after his favorite scientist.
Belowski – a boy obsessed with Mokey Mokey. He hypnotizes Jaden’s friends, including Alexis Rhodes, but he doesn’t take advantage of her. If that doesn’t show restraint, I don’t know what does.
Wheeler – a robotic monkey named after Joey.
Chancellor Sheppard – the equivalent of Professor Dumbledore in Yugioh GX. The only difference is that he can’t do magic, doesn’t have a secret crush on Jaden, and has never dueled someone named Gellert Grindelwald.
Atticus Rhodes – Whoever came up with this name must’ve been reading “To Kill A Mockingbird” not long before. He uses Red Eyes Darkness Dragon. He’s a surfer type who encourages Chazz in his useless attempts to win Alexis’ heart.
Ojama Yellow – This character is meant to provide humor relief when the show gets dark. If it were not for Ojama Yellow, some kids wouldn’t be allowed to watch this show.
I am skipping a lot of Yugioh GX, partly because this was a failure of a series. However, there are a few characters some people wouldn’t be able to forgive me for skipping, so I will list them.
Jesse Anderson – A boy who was raped by Amethyst Cat, and ever since then has found felines more sexually attractive than females. He replaces Syrus as Jaden’s best friend.
Tyranno Hassleberry – boy who loves dinosaurs because he got hit on the head with a bone. His favorite movie series is “The Land Before Time.” He has seen all seventeen of them twenty times at least.
Aster Phoenix – a failure of a boy in everything but dueling. He is rich and spoiled and he uses Destiny Heroes. Believes too much in fate.
Adrian – treated his girlfriend Echo like crap, because all he cared about was Exodia. What a loser.
Yubel – She/He/It had a crush on Jaden, until he stupidly sent Her/Him/It into space. She/He/It came back for revenge.
Jean-Louis Bonaparte – a man with a French accent whose cards are all based on toys. He is the father of a promising young man called Marcel.
Axel Brodie – his victory saved Jaden from being evil. He was only brought into the show because the other GX characters are white and minorities were outraged.
