INSERT-NAME-OF-SIBLING Mokuba Kaiba
- "No you shut up! ...Oh god I'm so sorry."
Seto's little brother, who he cares nothing about. He's frequently told to shut up and gets kidnapped a lot, and Kaiba is completely flippant about it at this point. his true father is Nappa. Ghost Nappa, to be precise. Probably, but likely not.
- Adaptational Badass/Adaptational Villainy: In Season 0, he's the Big Bad with Seto being his Dragon as he schemes to defeat Yugi and steal his most powerful cards to rule the world as "Emperor Mokuba".
- Beware the Nice Ones:
- His idea behind running a company is developing frustrating operating systems that nobody wants to develop for. He would call it Mokusoft.
- He also states that he can decide who lives and who dies because Kaiba is his brother.
- He gets incredibly hostile and vicious towards Joey for no apparent reason at one point, and Seto has to make him heel like a dog.
- Butt-Monkey: He's to insults and kidnapping as Bakura is to injuries and neglect.
- Crossdresser: Switched outfits with Princess Adina because he always wanted to look pretty. It's also implied he may have done this before.Kaiba: Why the hell were you dressed like a girl?Mokuba: Oh like you've never tried it.
- Deadpan Snarker: He gets a few moments of this, like when he's talking to Seto in Episode 67, or when he's calling out Noah for thinking he can just redeem himself right after firing a missile at them.
- Distressed Dude/Damsel Scrappy: In-universe with the latter one, at least. Exploited when he gets treats out of Noah by saying that that's what previous kidnappers did.
- Extreme Doormat: To Kaiba, and to a lesser extent, everyone else.
- It Gets Easier: He has been kidnapped so many times that when Noah does it in Season 3, he treats it like something common.Noah: I kidnapped you and there's no escape.
Noah: That's it!? Just "'kay"!?
Mokuba: Well, i'm kinda used to it by now.
- The Load: It varies, but he rarely does anything of value and just gets kidnapped.
- Lonely Rich Kid: Seto won't let him have friends as they tend to get kidnapped.
- Made of Iron: That fall he survived in Episode 6 would've killed or seriously injure pretty much any regular guy. Lampshaded by himself."Man, I sure am glad I'm a cartoon."
- Napoleon Delusion: Believed himself to be a Pokémon in Episode 28.
- Offscreen Teleportation: Done to Yami Yugi in order to steal his Star Chips. Yami thinks he did it through Super Speed.
- Older Than They Look: He's actually around Kaiba's age, considering that they both grew up together in that orphanage when they were children, yet he looks even younger than Yugi (who was once mistaken for a Elementary schooler). Kaiba lampshades this, pointing out how Mokuba is more or less the same height as when he was younger.
- Phrase Catcher: "Shut up, Mokuba."
- "I'm not gay, I'm just British!"
The present-time Bakura. Quite effeminate, and very, very British, he tends to get pushed in the background a lot by his evil side, who possesses the Millennium Ring.
- All-Loving Hero: No matter what happens, Bakura can't seem to keep a grudge towards anyone, not even against the evil spirit that's been controlling his body since the first season.
- Ambiguously Bi: Shows interest in Tea at one point, and Yugi in another. (Technically he says he's "not gay"...)Tea: Stop groping my Yugi-muffin!
Bakura: Bugger off! You had your chance.
- Camp Straight: Possibly. After all, he's not gay, he's just British. He even asked Téa if she fancied a shag once.
- Cannot Talk to Women: He tries to hit on Tea, but his speech pattern makes him look too weird for her.
- The Chew Toy: For a short time in Season 2. "I say Yugi, can I be in this episod- [insert horrible injury here] Oh bugger!" Repeat twice more with escalating levels of buggery.
- Demoted to Extra: Even more so than in the original series. Yami Bakura, on the other hand...
- Dude Looks Like a Lady: People, especially main characters lampshades this often by calling or mentioning him as "Shemale" (which he himself admits) or "sexually ambigous character".
- The Friend Nobody Likes: No one cares about Bakura at all. Yami claims he doesn't even know his name.
- Gaydar: His father installed this on his Millenium Ring because of his feminine appearance. Florence also used this feature to find gay energy source for himself to use.
- I Am Very British: Mocked repeatedly.
- Last-Name Basis: No one bothered to ask what his first name is (nor do they care when he finally tells them).
- Mistaken for Gay: He's not gay, he's just British. Flipped for his Superpowered Evil Side; Yami Bakura is not British, he's just gay.
- Momma's Boy: In episode 16:Tristan: Nobody cares about what you want!
Bakura:...My mummy does...
- Shipper on Deck: Debatable, but interestingly enough, every time he has shown up in the creator's spinoff fanfics he's been subtly helping Yami Bakura and Marik together. This despite the fact that he's Out of Focus most of time because of his dark side. Why he bothers, no one really knows.
- "You guys are making me sexy. You won't like me when I'm sexy."
Duke Devlin is the creator of Dungeon Dice Monsters, a game that is totally different from Duel Monsters and is definitely not that game with dice added. He is incredibly sexy and handsome, to the point no one, man or woman, can resist his charms. He has his own theme music, "Sexy Back," which plays constantly as he speaks, but he may or may not notice it.
- Anything That Moves: It's heavily implied he's bisexual, he's open to aliens anally probing him, and he makes a joke about "riding" the robotic Nesbitt. Also, his idea of unlocking doors in Industrial Illusions during Season 4? By tricking the security system to have cyber sex with him, proving that he has no problem with a computer program.
- Berserk Button: He hates it when people point out the similarities between Dungeon Dice Monsters and Duel Monsters.
- Bishōnen: He's very pretty. Lampshaded constantly.
- Butt-Monkey: A lesser example; his Dungeon Dice Monsters game is frequently addressed as being "exactly like Duel Monsters".
- Defeat Means Friendship: By Yami. After his defeat he apologizes and asks if they can be friends in Season 2.
- Dude, She's Like, in a Coma!:Duke: "Want to know the best thing about unconscious chicks? They can't say no." [everyone looks at him] "What? Oh, yeah, like I'm the only one thinking it!"
- Even the Guys Want Him: Men and women are both powerless to resist Duke.
- Hollywood Hacking: Or as he puts it, tricking the system into having cybersex with him.
- Intimate Healing: Up to Eleven. He has this weird disease where if he doesn't have half dressed women around him at regular intervals, he dies. Tristan offers to help him but men don't do it for him.Duke: (after Tristan and him found Serenity in the Virtual World) Hey baby, mind if I take your top off for a minute?
- Leitmotif: The number of times his theme song (Sexyback by Justin Timberlake) doesn't play while he speaks is only in the single digits. Also, while everyone else can listen to his theme, he himself can't hear it and is confused when others point this out.
- Usually. Other times, he directly refers to it, and even sings along to the tune. As of Season 4 he can definitely hear it... and he has to go Commuting on a Bus for a little bit because he just realized he's had it running for four entire seasons without recharging it.
- Loveable Sex Maniac: Virtually every line of dialogue he has is a crack about sex.
- Narcissist: He considers his reflection the most beautiful thing in the world, and has no shame about bragging about his sex appeal.
- Only Sane Man: He has his moments of this. When Tristan and Serenity want to open the Obviously Evil door, Duke suggests they not.
- Running Away to Cry: This happens in Season 4.Duke: No, Tristan! Because it's not! Dungeon Dice Monsters uses dice!Joey: I activate my trap card, Skull Dice! A card that very specifically requires a die to play it!Duke: Oh God, look at the time! I have to be somewhere. *Duke ran away crying*.
- Surfer Dude: Dabbles in it a little, but not as much in later seasons."Gradius, totally attack his Life Points!"
- Third-Person Person: Does this from time to time."Duke Devlin is gonna throw up!"
- What Beautiful Eyes!: Lampshaded by Joey.
Solomon Muto / Grandpa
- "I'm checking the obituaries to see if I've died yet!"
Yugi's grandfather. A simple shopkeeper and stereotypical, senile grandpa with a death wish and some incredibly quirky... habits. Best not to pry into it: you will come back mentally scarred.
- Adaptational Wimp: This version of Solomon is far from his original counterpart. Canon Solomon was a skilled Duel Monsters master who taught Yugi and Joey everything they know about the game and is a somewhat valuable asset to the group a few times, while Abridged Solomon is nothing more than a bumbling idiot who is bossed around by his own grandson.
- Basement-Dweller: According to Yugi, he lives in the basement of the card shop.
- Bread, Eggs, Milk, Squick: Interspersed throughout his rant at the end of the movie."You kids these days and your Millennium Items, and your card games, and your loud music and your hula hoops and your hopscotch and your dungarees and your lollipops and your Sony Playstations and your voice-activated light switches and your leather pants and your artificial insemination— (cut off by Yugi, then continues after the credits roll) —your Blu-Ray Discs and your pierced scrotums..."
- Cloudcuckoolander:"Where am I? What day is it? I like pudding!"
- Dad the Veteran: Bores Yugi with his war stories in Episode 62. Based on pretty much everything he said in BBT Abridged (such as thinking that America was invading them when the fireworks went off), he might be a (Japanese) veteran of WWII.
- Retired Badass: Assuming that he wasn't just babbling nonsense like the Cloud Cuckoo Lander he is, not only is he a war veteran, but his story in Episode 62 begins with him mentioning that he single-handedly slaughtered an entire squadron of something (probably soldiers, but knowing him, it could've been a squadron of anything).
- Death Seeker: For some reason, he's very eager to die.
- He gets his wish in Bonds Beyond Time Abridged.
- Dirty Old Man: Lusts over numerous females.
- Everyone Calls Him Grandpa: In fact, Yugi didn't even know he had a name until Rebecca brought it up.Rebecca: I'm looking for Solomon Moto.Yugi: Who the hell is Solomon Moto?Tea: Yugi, that's your grandpa.Yugi: He has a name?!
- Grumpy Old Man: A cynical and tired thing, he is. See When I Was Your Age....
- The Load: Probably even worse than Mokuba. Grandpa is there to be made fun of and get injured.
- Perverse Sexual Lust: He has a not-so-secret love affair with his Black Luster Soldier poster.
- When I Was Your Age..."You know, in my day, we didn't have Duel-Domes. We had to play our card games out on the street, and our cards weren't even real cards. They were just rocks we picked up off the ground, and then we threw them at each other. Come to think of it, it wasn't really card games at all. We just liked to throw rocks at each other. Mostly at me. That's probably why I have so much self-loathing. Anyway, we should probably go over there."
Mai Valentine and Her Breasts
- "My breasts are not fake!"
A supposedly world-class professional duelist, Mai repeatedly proves herself completely incompetent every time she duels. She also happens to have enormous breasts, which are objects of pride for her and obsession and mockery for everyone else. In Season 4, she suddenly gets a change of voice and a rather expanded characterisation.
- Adaptational Heroism: Ironically, while being a villain. In the original anime, she was haunted by memories of her Shadow Game with Yami Marik and joined Dartz to be stronger, and was brainwashed into hating Joey and becoming convinced she had to beat him to overcome her past. Here, she wants to duel and beat Joey because she's sick of being treated as a one-note joke character only recognized for her breasts, and also for them leaving her comatose body alone on the airship during Season 3.
- Adaptational Villainy: Mai was repeatedly forced by the Orichalcos to fight Joey in the both the Subbed and Dubbed version of the anime every time she reconsiders dueling him, while Abridged Mai is implied to hate her friends entirely of her free will.
- Catchphrase: Often refers to herself as "My breasts". She seemingly dropped this as of Season 4, but appears to replace it with variants of calling herself "sexy".
- Crossdressing Voices:
- Also voiced by the male Little Kuriboh in an even less convincing voice than Téa's. Lampshaded when Johnson disguises himself as her but has the same voice, and Joey notes that Mai sounding like a man is totally normal for her.
- Averted in Season 4, where she's voiced by BoobsMcbalrog. The change is noticed by Joey.
- Faux Action Girl: Exaggerated and Played for Laughs here. Despite supposedly being a world-famous pro duelist, every time Mai duels on-screen, she loses or surrenders. It takes a pathetic filler character, Jean Claude Magnum, to finally let her have a victory.Tea: "I can't believe we found a duelist even worse than Mai!"
- In Season 4, this is one of the reasons why she has gone evil; she's basically sick of being treated as a joke despite having a huge winning streak off-screen on the professional circuit after Battle City. When Joey claims that "if it happened off-screen, it didn't happen", Mai humiliates him by basically saying "by that logic, then your balls haven't dropped". The only reason she loses the duel against him is because he basically cheated.
- Gag Boobs: Everyone thinks her breasts are fake, and they squeak when she lands on Joey."It's finally happened; I killed a man with my breasts!"
- Hypocrite: :At the end of season 3 Mai leaves Joey for nor knowing anything about her other than her breasts, while this does get changed to something more reasonable, later in season 4 one of the reasons she cites for her FaceHeel Turn was frustration of everyone talking about her breasts, despite before then much everything Mai said or did concerned her breasts in some way, to the point her Ironic Hell was a world where everyone else's breasts were bigger than hers.
- I Have Boobs, You Must Obey!: Loves to use her sex appeal to command others.
- Ironic Hell: After losing to him, Melvin sends her to a dimension where everyone's breasts are bigger than hers (especially Tristan's).
- Jerkass Has a Point: The reason for her FaceHeel Turn in Season 4 is that she found out the cast left her comatose body alone on the blimp with the psychotic Melvin while they took part in the Filler Arc. Admittedly a good reason to be angry.
- Ms. Fanservice: Her whole shtick is how attractive she is and how large her breasts are. Well, it was before Season 4, at least. Though even after her character development, those are still prominent traits of hers (uh...).
- My God, What Have I Done?: Played up to an even more ridiculous degree than the anime when Joey loses his soul in Season 4. At least in the original show, she was brainwashed against her will and exhausted Joey until he could no longer continue the duel, making her feel responsible for his fate. Here, she joined Dartz of her own volition, had very valid reasons to hate Joey, and had hardly even made a move before he passed out, yet the moment he loses causes her to instantly regret everything she'd done.
- Of Corsets Sexy: Wears a tight white corset.
- Proud Beauty: Always talks about her breasts in front of other people just so they notice and even after her FaceHeel Turn, she still takes pride in becoming sexier upon becoming evil.
- Punny Name: Mai/My Valentine. She admits it's not very subtle, but then "nothing about [her] is very subtle."
- Really Gets Around: Probably not true, but everyone else thinks so.
- Weakness Turns Her On: "I just love broken men."
- What the Hell, Hero?: When Joey claims they were best friends, she retorts that he left her comatose body on a blimp with a known Serial Killer.
- With Friends Like These...: She's supposedly friends with the main characters, yet she's treated purely like a sex object and frequently forgotten by them, particularly Joey. This leads to her temporary FaceHeel Turn in Season 4, though it doesn't last because no matter how much she may resent Joey, he was still someone she cared about.
- "Because shut up."
Marik's sister and holder of the Millennium Necklace, who helps the heroes foil his plans. She knows that there is a darker plot brewing, however, and her actions are to avert a terrible disaster she senses in the future; the cancellation of the series.
- Ambiguously Gay: Florence's Millennium Gaydar led him straight to her. Supported by the fact Ishizu is never seen being attracted to any men.
- Because Destiny Says So: She believes her prophecies are infallible.
- Breaking the Fourth Wall: Her necklace's power lets her do this.
- Calling the Old Man Out: Yugi flat out says she and her whole family is responsible for Marik's Start of Darkness and that they're all batshit crazy.
- Cargo Ship: She's in a relationship with the Pharaoh's tablet.
- Catchphrase: "Because shut up," and "You know the one." The former phrase gets gets turned back on her by Melvin:Ishizu: Why, Melvin? Why are you doing this to us?Melvin: Because shut up.
- Crossdressing Voices: Another female done by Little Kuriboh. It's actually slightly more convincing than the others.
- Nice Job Breaking It, Hero!: Like in the canon, her decision to show Marik the surface began his Start of Darkness. Not only did it give him the taste for freedom that would cause him to reject the tombkeeper lifestyle, but it enraged their abusive father enough to beat them once he found out, causing Marik to snap and his evil personality to come out and kill him.Ishizu: I then realized that defying thousands of years of family tradition and spitting in the face of our insane father was probably not the best idea I've ever had.
- Not So Above It All: Tries to be the voice of reason on the show, until someone points out the flaws in her logic.Because shut up.
- Only Sane Woman: Probably the closest this series gets to sanity, anyway.
- Sibling Yin-Yang: A classic example between her and Marik. Ishizu is an no-nonsense Only Sane Woman, while Marik is a Large Ham Cloudcuckoolander. Lampshaded by herself.Rare Hunter/Steve: Master Marik, can we ride with you?Marik: No! Get your own friggin' motorcycles! See you guys at Wal-Mart!Ishizu: How am I related to him?
- What Kind of Lame Power Is Heart, Anyway?: Her Millennium Necklace gives her the power to break the fourth wall. Everyone can do that freely, anyway. However, she does manage to break the actual fourth wall, in the sense that while all of the characters talk about their lives and the events of the plot as if they're aware of their being in an official English dubbed anime series, Ishizu is one of the only characters who acknowledges in the episodes themselves that they are in an abridged series on the Internet. Such acknowledgement is usually reserved for other videos featuring the characters, not in episodes of the series itself.
- Women Are Wiser: More grounded and sensible than her father and brothers. Then again, given how dysfunctionally stupid Marik is and gummy bear-obsessed Odion is, the bar wasn't set that high.
- "I'm scared they'll write me out of the show. I mean, what purpose does my character even serve at this point?"
Joey's little sister who went blind because Joey spent the prize money meant to pay for a critical eye operation on trading cards. However, she later got better and joined the main cast, though she feared she was superfluous and risked being written out.
- All Girls Like Ponies: She opens a door promising ponies, only to find a fire-breathing hellhound. She shuts the door, but opens it thirty seconds later after being promised a pony again. Her theme music also features this.
- Aww, Look! They Really Do Love Each Other: Moments after regaining her eyesight, she dives into the ocean to save Joey from one of Marik's deathtraps, because no matter how badly he treats her, she'll always love her big brother.
- Butt-Monkey: Not as much as Tristan, but still applies. First, Joey spends all the money that was supposed to go to her operation on trading cards, then she gets the operation anyway, it's a failure, and she spends several episodes in the hospital annoyed by visitors. Joey also repeatedly shows no concern for her wellbeing, and as noted under Satellite Character, she just exists for Tristan and Duke to pine over.
- Crossdressing Voices: The fourth main female LK voices.
- Girly Girl: She's obsessed with ponies and acts stereotypically girly. The only thing missing is a feminine sounding voice.
- Ill Girl: Until her eyesight comes back, she was blind and Joey's motivation for duelist.
- Lust Object: Tristan wants Serenity. In the worst way possible.
- Only Sane Man: Has her moments when she notices the insanity going on and dislikes it.
- Satellite Character: Lampshaded during the season three premier. She questions what purpose she serves anymore, and when Joey tells her it's to give Tristan and Duke something to do, she "feels so much better about [herself]."
- Screw This, I'm Outta Here!: At the end of Episode 63, Serenity gets progressively more fed up with Téa having pointless flashbacks instead of going to the mall like they planned, until Téa crosses the line by bringing up Serenity's hospitalization and the divorce of her parents, at which point she just says that she wants to go home.
- This Is Gonna Suck: Serenity has this reaction in the second Recap Episode whenever Téa starts reminiscing fondly about certain events that Serenity found traumatizing.
- Tomboy and Girly Girl: Girly Girl to Tea and Ishizu's Tomboys.
- Unexplained Recovery: Unlike the canon where she got the operation and recovered, in this show the operation was a failure and she went fully blind. However, eventually the "writers" decided to make her a regular character and thus she miraculously got her sight back shortly after.
- Unwitting Instigator of Doom: She was responsible for the death of Noah by running him down, leading to the Virtual World/Cancelled Series arc.
- Vocal Dissonance: Played for Laughs. While Téa sounds like a high-pitched male and Mai sounds like a drag queen, Serenity has the honor of sounding like a Muppet. It apparently runs in the family: her mother sounds like Doctor Girlfriend.
- Younger Than They Look: According to Duke, she's 12-years-old. No wonder Joey threatens to kill Tristan for wanting to date her.
