Let's Duel!

I made a wish on that puzzle... for friends I could count on... friends who could count on me! No matter what!

IT'S TIME TO D-D-D-D--D-D-D-D-D-D-DESCRIBE!

There were actually two Yu-Gi-Oh! anime series: The first anime, which covers the first seven volumes of the manga, made by Toei Animation; and this one, Yu-Gi-Oh: Duel Monsters, which was produced by NAS, animated by Studio Gallop, and is adapted from volume 8 onwards.

This adaptation is given the subtitle "Duel Monsters" to demonstrate the elevated prominence of the card game compared with the manga and first series anime (though the manga at the time was also given the subtitle of "Duelist" in the English localization). It was sponsored by Konami as a successful attempt to remain dominant of the license to the card game, after it stripped it away from Bandai, which failed to retain the license of capitalizing on the manga's card game with Toei's movie and anime.

There are a huge number of video games based on the anime and manga. It also spawned a movie called The Pyramid of Light. This version of Yugi and his alter ego return in the Yu-Gi-Oh!: Bonds Beyond Time that teams him up with Jaden and Yusei.

This show in particular is also responsible for the creation of The Abridged Series genre of internet videos, with Yu-Gi-Oh! The Abridged Series.

The dub is available on Hulu, the official Yu-Gi-oh website, and is now starting to appear on Netflix.


"It's time to trope!"

    open/close all folders 

    A - M 
  • Abandoned Warehouse: Bandit Keith duels Yugi in an abandoned warehouse that has its own Duel Monsters arena.
  • Aborted Arc: Beginning in Season 2 of the anime, the stone tablet that continues to be a plot point for the rest of the series shows Kaiba and Yugi dueling in ancient Egypt. Isis/Ishizu shows Kaiba a vision of the battle. Later, in Season 3 another vision of this battle is shown, but it's completely different from the vision showed before. The battle is seen first-hand in Season 5, and is rather underplayed given the amount of foreshadowing and importance given to it before. Furthermore, though they differ greatly, both visions show Kaiba is quite clearly the Pharaoh's enemy, but in Season 5 he's completely loyal and the only reason the battle occurs is because he gets possessed. This is attributed to Kazuki Takahashi never getting to flesh out the story with Seto and Kisara the way he wanted, and Seto rebelling against the Pharaoh was intended to be a larger plot point that didn't end up happening.
  • Absurdly High-Stakes Game: Shadow Games and Duel Monsters. The world is frequently at stake. Also, the Doma arc has the characters losing their soul if they lose while the Seal of Orichalcos is in play, meaning effectively the loser is left with an empty shell of a body.
  • Abusive Parents: Gozaburo Kaiba, and Marik and Isis's father.
  • Accent Adaptation: In the 4Kids dub, Joey/Jonouchi was given a Brooklyn accent to represent his plain speech patterns in the original. Ryou Bakura was given a British accent to reflect his politeness.
  • Acting Unnatural: Since he and Anzu/Tea are stowaways on the ship to Duelist Kingdom (and Joey isn't really supposed to be there either), Honda/Tristan advises everyone to "act casual" going past the guards... and then marches past looking ridiculously uncomfortable and suspicious.
  • Adaptation Dye-Job: The Blue-Eyes White Dragon is more blue than white, and the Dark Magician went from having red and black armor, green skin, and blond hair to purple armor, fair skin, and purple hair.
  • Adaptation Expansion: The Big 5. In the manga they are just faceless goons in the shadows who cooperate with Pegasus, but in the anime each is given a name and a clear personality, primarily during the Virtual World arc.
    • Pandora/Arkana's lover is expanded on; in the manga she was never named and was a secondary reason for him joining Marik (the first was grief over the death of his mother). In the anime she's given the name Cadeline/Catherine, and his reason for joining Marik revolves around trying to win her back.
  • Adaptation Explanation Extrication:
    • Dark Yugi stops giving his Penalty Games after Duelist Kingdom for no explanation in the anime. In the manga he stops doing this when Pegasus says the items have an evil intelligence, as he does not want to be evil, whereas in the anime he plays a Shadow Game with Shadi right after defeating Pegasus. The Black Clown's clown theme and Ryuji's partial clown make-up makes more sense in the manga as well, as his father was cursed to have a clown face.
    • Grandpa getting severely injured through a card game for no rational explanation. In the manga, he gets the "Experience of Death" penalty game after losing to Kaiba, which is Exactly What It Says on the Tin. In the anime, that never happens, and he is injured because of the incredibly realistic holograms, even though he is okay with them later on.
    • The anime never explains why Dark Bakura is after Mokuba in Duelist Kingdom (it's for the key to Kaiba Corporation's safe). The dub actually makes a little more sense, with him being after Mokuba's body instead, even though it still creates a plot hole (Bakura is the Chosen One for the Millennium Ring and the Shadow RPG).
    • Pegasus somehow finding out about Kaiba's defeat at the hands of Yugi during the first episode, in which the only witnesses to the duel are Jonouchi and Mokuba. It makes more sense in the manga, where there is an entire audience of Kaiba fanboys overlooking its equivalent to the first episode match during the Death-T arc.
  • Adaptation-Induced Plot Hole: Skipping the first seven volumes and cramming the development into Duelist Kingdom, along with dozens of added anime-exclusive details and the removal of certain details from the manga, creates exclusive plot holes for the anime that aren't present in the manga. For example, the Millennium Items were given powers in Duelist Kingdom that defy the rule of playing games to punish people, such as the Ring being able to summon monsters into reality and the Eye trapping Mokuba's soul without the need for a game. These points were dropped post-Duelist Kingdom.
  • Aerith and Bob: By-product of dubbing. 4Kids gave new names to only some of the characters, resulting in completely typical sounding names like Joey, Tristan, and Duke appearing alongside characters like Yugi, Seto, Mokuba, and Bakura.
  • Alternative Foreign Theme Song: As with all the anime that 4Kids dubs, the English opening is different from the Japanese opening. You can listen to it here.
  • Amulet of Concentrated Awesome: Yugi's Millennium Puzzle, given that it has the soul of a 3000-year-old Pharaoh in it (5000 in the dub) and tends to be generally badass when it takes over Yugi's body. Actually, most of the Millennium Items in general fit this trope.
  • Ancient Egypt: A large chunk of the characters and artifacts come from this time period. It is also the backdrop of the final Shadow Game.
  • Angel Face, Demon Face: The differences between Yugi, Bakura, and Marik's normal appearances and when their Yami sides take over. Though, Yami Yugi isn't the most demonic per se, and normal Marik isn't the most angelic.
  • Animation Bump: As a general rule of thumb, the more important episodes are animated with an art style which is superior to that seen during other episodes. The opening/closing sequences are also animated using a cleaner animation style.
  • Anime Hair: Yugi is a particularly egregious example. All the supporting characters except for Tea/Anzu tend to be trying to outdo each other in outlandish hairstyles, as well.
  • Arc Words: "Something that you can see, but something that can't be seen" gets repeated quite a lot, at least early on. Originally it referred to the Millenium Puzzle, but it's used to refer to many different things by altering the way the line is interpreted.
  • Artifact of Doom: Millennium Items tend to give their owners awesome Psychic Powers of some sort. However, more often than not, they will also harbor or lead to the development of their owners' Superpowered Evil Sides, or at least contribute to their Face-Heel Turning.
  • Artifact Title: "Yu-Gi-Oh" means "Game King." The anime rarely featured other games besides Duel Monsters, and non-DM games generally had Duel Monsters inserted anyway.
  • Artistic License – History: Beyond the parts that never would have been accurate to begin with (Obelisk as a God, the costumes, the fact that most of the characters in the Memory World are going around with their own hair), other Anachronism Stew mistakes crop up, such as people using what seem to be steel or iron swords during what should have been the Bronze Age. Doubly the case for the dubbed version, which changes "3000" to "5000": Five thousand years ago—3000 BCE—would have been before the pyramids were built, and horses weren't introduced to Egypt until around 1700-1550 BCE.
  • Art Shift: Once Yami defeats Kaiba and performs a mind crush on him, his face becomes less angular and his eyes gain pupils.
  • Ascended Extra: The Big 5, Gozaburo Kaiba, Johnny Step, and Professor Hopkins were all minor characters in the manga but were given expanded roles in the anime.
  • Ascended Meme: The nicodouga phenomena relating to the "Enemy Controller" scenes from the Virtual Arc is referenced in a minigame on the Duel Terminal arcade game.
  • Astonishingly Appropriate Appearance: A few of the minor characters.
    • Weevil Underwood, whose bowl-cut hair is described as looking like a blue beetle, and his glasses have a beetle motif to them. He uses an insect-themed deck.
    • The pale and sickly-looking Bonz uses an all-zombie deck.
  • Attempted Rape: In a flashback, Anzu is lured into a gym hall where a creepy gym teacher with a camera was waiting to blackmail her for going to work at Burger World against school rules. Luckily like the manga where Dark Yugi challenges both of the equivalent assailants to Shadow Games and inflicted Penalty Games on them, Yugi arrives on time and Dark Yugi emerges to play a "draw the stronger Duel Monster" Shadow Game and gives the pervert a "Mind Crush" Penalty Game. In the dub, the camera (and shots of Anzu's thighs) were edited out, and she's assaulted by a mugger instead.
  • Awesome, but Impractical:
    • Pretty much every character's deck only works because of The Magic Poker Equation and the fact that the writers can let them get whatever cards they need. For a fun drinking game, watch the show and take a drink any time a duelist's strategy could be utterly ruined with any simple one-for-one destruction card like Mystical Space Typhoon or Smashing Ground — cards that no one seems to use, not in multiple copies at least.
    • Rare cards in-universe are rare cardsnote , which most of those destruction cards are (e.g., Harpie's Feather Duster).
  • Ax-Crazy: Yami Marik and Yami Bakura (the latter is more Wicked Cultured in the dub, but still has shades of this). Even our hero Yami Yugi can become Ax-Crazy if you push the right buttons.
  • Badass Adorable: Yugi, mostly because the anime puts more emphasis on his youthful looks, compared to Atem.
  • Badass Normal:
    • Yugi — the normal one, not the Pharaoh one — manages to take out all three God Cards in one turn against Atem.
    • Jonouchi, as well, who's the most normal of the main duelists.
  • Bait-and-Switch Credits: The final opening for the Millennium World arc ("Overlap"). Aside from Kaiba's presence in the opening and a couple of Adaptation Dye Jobs/Dark Yugi-tallness, the opening is actually more faithful to the manga version then the anime version. For example, there is toothless Ra (anime Ra had teeth, manga Ra did not) and has the main characters where their school uniforms while in Egypt (they wore different clothes in the anime). The opening even lacks the Ancient Egyptian Duel Disks that the priests had in the anime but didn't have in the manga.
  • Beam of Enlightenment: Any time one of the characters has a sudden revelation. Mostly when Yami figures out how to beat his opponents. It happens when Yugi collapses during his second duel with Pegasus. Yugi's friends can sense it, despite his isolation in the Shadow Game.
  • Beauty Equals Goodness: The heroes' ace monsters are drop dead gorgeous, even the Blue-Eyes White Dragon looks noble and majestic. Meanwhile, the villains use monsters that wouldn't look out of place in horror movies.
    • Bakura and Marik are both good-looking, but when their Superpowered Evil Sides take over, they look significantly rougher and are prone to making terrifying faces.
  • Beethoven Was an Alien Spy: Capsule Monsters only: Alexander the Great had the Millennium Ring.
  • Berserk Button: If you don't want to see a very angry Kaiba, don't tell him Yugi lost a duel. Or try to take over his company. Or attempt to kidnap/harm Mokuba.
  • Between My Legs: This shot is how Rebecca is introduced in her first appearance.
  • Beware the Nice Ones:
    • Ryou Bakura is a very sweet, shy, quiet, polite guy with a Superpowered Evil Side that he's only vaguely aware exists.
    • Yugi, later on in the series, shows that he has the ability to kick ass even without his Other Personality, at times.
  • Big Bad: Kaiba, Pegasus, The Big Five, Noah/Gozaburo, Marik, Dartz, and Zorc/Bakura. Subject to the Sorting Algorithm of Evil.
  • Big Damn Heroes: Seems to happen a lot. Notable because oftentimes the mere presence of the friends of whoever is dueling gives them the strength to win, or at least continue playing into the next episode.
  • Big "Shut Up!": Pegasus tells Dark Bakura to shut up after the latter reads his past like an open book through Duel Monster cards used as Tarot cards.
  • Bilingual Bonus:
    • Played straight with the Egyptian text. Atem's name is written as "Atemu" and the carvings on Rishid's face and Malik's back are genuine hieroglyphs. The author knew what he was doing.
    • Subverted with the Enochian text on the Orichalcos cards, which is a random jumble of nonsense. However, the card title spells "Orichalcon" and the rim of the seal spells "Oreichalcos" twice.
  • Bishōnen: Marik Ishtar, Ryou Bakura, and Ryuji Otogi/Duke Devlin. The latter two even have their own in-universe fan clubs.
  • Bitch in Sheep's Clothing:
    • The spirit of the Millennium Ring. He uses the innocent Bakura as his "sheep's clothing". One can almost never be sure who is in control, as one second Bakura is smiling innocently, and the next second when the others have turned their backs the spirit smirks.
    • Marik. When he personally meets up with Yugi's friends for the first time, he pretends to have just found Bakura injured. He actually does this to gain their trust. He introduces himself to them as "Namu", acting as a humble beginner who is participating in the Battle City Tournament. Right afterwards Marik's minions attack and Anzu and Jounouchi get kidnapped, then brainwashed. He keeps up the innocent act later, too, claiming to having gotten into the finals only because of dumb luck, even as Jounouchi grows suspicious of him. Now, Marik's past and his dark side business considered, he still shows a rather malicious personality on his own. He doesn't seem to regret any of his actions, either, except for getting Rishid hospitalized and the fact that he had blamed pharaoh for the death of his father. Rather, he's just confused as to why Yugi would want to help him after he tried to kill them all. So, it might be that he's still a bitch in sheep's clothing when we see him again later in the series, just maybe not to the same extent as before.
  • Black Box: The IC chips inside the cards are described as this in the Pyramid of Light novelization.
  • Black Cloak: Marik Ishtar and the other Rare Hunters are garbed like this when they are first introduced.
  • Bowdlerise:
    • Of the manga: skipping approximately the first seven volumes of Dark Yugi challenging bullies/criminals to Shadow Games and inflicting Penalty Games (a flashback replaces Dark Yugi's infamous "One Finger Battle" game with "Draw the strongest Duel Monsters card"), disregarding Kaiba's death-themed amusement park, changing the few of Dark Yugi's Penalty Games that they're willing to show into kid-friendly "Mind Crushes," etc. — among other things. Duelist Kingdom, DDD, and Millennium World get most of this treatment, whereas Battle City gets less of it (most of it comes from Dark Marik).
    • The English dubbed anime is this to the above, notably in Battle City. Marik's rare hunters can't invoke shadow games since they don't have millennium items and instead set up elaborate death traps. The English dub insisted that they were shadow games anyway, thereby opening up a number of massive plot holes.
  • Breakout Character: The Dark Magician Girl, being the Ms. Fanservice of the franchise, is far more popular than any other duel monster from the original series save for the iconic Blue-Eyes and Dark Magician. She's even playable in some of the video games.
  • Breather Episode:
    • A breather arc, actually. The relatively laid back KC Grand Prix story fits right in between the much more intense Doma and Millennium World storylines.
    • The anime version of the Dungeon Dice Monsters story serves as this as well.
  • Broken Bridge: The only thing that keeps Marik from interfering in the events of Noah's Arc is... a locked door. Although, he does manage to blow up Noah's control system.
  • But Now I Must Go: Atem has to pass on to the afterlife after he saves the world from the Shadow Games once and for all.
  • Calling Your Attacks: "DARK MAGICIAN, DARK MAGIC ATTACK!" "BLUE EYES, COUNTER WITH WHITE LIGHTNING!" and so on ad infinitum. Several of these attacks even have their own cards, which require their monster to be out. Mainly used for important monsters early on, with smaller ones just getting descriptions of what is happening, but later in the series and on through GX and 5D's it reaches silliness of epic proportions.
    • Yami Yugi seems to use "OBLITERATE" often, for both Exodia and Blue-Eyes.
    • Characters will sometimes tell the one calling the attacks to shut it.
  • Calvin Ball: Duel Monsters is closer to this in Duelist Kingdom, since the manga storylines and the related cards were closer to an RPG at the time, leading to Normal monsters having effects, being able to destroy your own spell cards, and field power bonuses affecting both sides.
  • Card Games: Duel Monsters.
  • CCG Importance Dissonance: Countless examples, the most famous of which being the Dark Magician, Blue-Eyes White Dragon and Red-Eyes Black Dragon.
    • Those cards did have importance in the early days of the card game, since effect monsters and monster removal, amongst other meta-defining concepts, were few and far between at the time, thus making the game more about which monsters had the higher stats, with BEWD in particular standing alone at the top.
    • Even now, most monsters with 3000 or more ATK have some form of summoning conditions to keep Blue-Eyes White Dragon unique (although these conditions often make such monsters easier to summon).
  • Chained by Fashion: Exodia has chains on his wrists and ankles.
    • Yugi later uses a chain necklace for his Millennium Puzzle.
  • Charles Atlas Superpower: Kaiba can throw cards at someone with such force that it hurts like they're shuriken, Jonouchi can break down a wall, etc. Each of them have almost no visible muscle.
  • Chastity Couple: Mai and Jounouchi/Joey. Also Yugi and Anzu/Tea, though the latter has a crush on the former's superpowered evil side.
  • Chekhov's Gun: In the Duelist Kingdom arc, Joey is seen trading for Sword and Shield, which he later uses against Ghost/Bonz to pull off a win. He gets Kunai With Chain and Salamandra in the same trade, which he uses to defeat two troublesome monsters in the team duel with the Paradox Brothers, as well as Baby Dragon, which combined with the Time Wizard given to him by Yugi ends up finishing off Mai in his first duel with her.
    • Kuriboh makes a blink-and-you'll-miss-it appearance in episode 5 to diffuse one of Weevil's traps, before Yugi brings it back in episode 24 to hold off Kaiba's Blue-Eyes Ultimate Dragon.
    • Another, ultra-delayed Chekhov's Gun comes from the first title sequence, where Yugi's shadow splits in two, representing his two sides. 220 episodes later, this happens when Yami and Yugi face each other in the ceremonial battle.
    • If the camera ever pays particular attention to the cards that players put in the graveyard when they have to discard cards for some reason, it's likely (though not guaranteed) that at least one of those will have an effect that works in the graveyard, or that the player will otherwise get to use that card later on.
  • Cherry Tapping:
    • Yugi manages to stall off Kaiba's Blue-Eyes Ultimate Dragon with Kuriboh, labeled as the weakest monster in the game.
    • Yugi seems to have a thing for using weak monsters to deliver a disproportionate bitch slap to his opponent.
    • Whenever he played Capsule Monsters, the game was rigged so that Yugi's monsters were all weaker than his opponent's, yet he destroyed them anyway.
  • Collectible Card Game: Duel Monsters, which the entire series is centered around.
  • Cooking Duel: Figuratively speaking. The series often stakes the lives of its characters, or even the fate of the world, on a game of Duel Monsters.
  • Curb-Stomp Battle: Several examples throughout the series, mostly involving a character getting extremely lucky early-game draws, thus being able to wipe out their opponent very quickly, or their opponent being hilariously inept.
  • Also, the first Yami/Kaiba VS Rare Hunters battle. Kaiba summons Lord of Dragons AND special-summons all three Blue Eyes and a spare dragon in just the first move, then summons Obelisk on Round Two (sacrificing his Blue-Eyes to do so) AND sacrifices his other remaining monsters to activate Obelisk's Total Party Kill special ability to defeat both opposing players (the Pharaoh, for what it's worth, only has enough time to play Kuriboh while all of this is going on except Kaiba wanted to flaunt power).
  • The Dark Side: Many characters in Yu-Gi-Oh! fall into some Dark Side's trap, usually by trying to use an Artifact of Doom (e.g., Marik, Bakura, Pegasus, Aknadin). Yami Yugi is not immune to this effect.
  • Dead Man Writing: Subverted with Pegasus in the Doma filler saga. He isn't dead, merely comatose due to his soul being removed. However, one could bring up the manga here...
  • Deadpan Snarker:
    • Later in the 4Kids dub, Bakura is quite good at this.
    • Kaiba is another.
      Gozaburo: I treated you better than my own son!
      Seto: Thanks for nothing.
    • And again:
      Seto: Anyone who's late to my tournament will automatically be disqualified. Mokuba, make sure Wheeler's late.
    • From the Waking The Dragons arc:
    Kaiba: So you have a dweeb army. Am I supposed to be scared to attack?
    Dartz: Well, only if destroying an innocent soul concerns you.
    Kaiba: Nah. As the president of a major corporation, I have to do that every day.
  • Debt Detester: Kaiba claims that Tea helping Mokuba escape from the Rare Hunters is the only reason he's helping Yugi find his friends. Then he uses it as his reason for saving Tea's life. Considering all the times he makes a point of explaining how he's only "helping" the gang out of selfish reasons, it's pretty clear that it's a shield for his Hidden Heart of Gold.
  • Defeat Means Friendship: Ryuji Otogi/Duke Devlin in the Dungeon Dice Monsters arc. To an extent, Mokuba Kaiba and Marik Ishtar later on.
  • Defrosting Ice Queen:
    • Mai Kujaku/Valentine for the first few arcs, and then heads back to Arctic levels during most of Season 4 due to her Face–Heel Turn.
    • Kaiba is a male example, at least in the Japanese version. He becomes more amiable and less openly insulting towards the others over time.
  • Demoted to Extra:
    • Ryou Bakura in the second anime. In the manga, he appears with the main group most of the time after his initial appearance and has tons of screentime, whereas in the anime he usually only appears whenever it involves Yami Bakura or if it's Yami Bakura pretending to be the real Bakura. This is so bad that on the official Yu-Gi-Oh website, Ryou Bakura does not have a character profile but Yami Bakura does. The same goes for the official Japanese websites.
    • Bobasa as well, as his major role in the Millennium World arc from the manga was instead given to Shadi whereas he is mainly reduced to comic relief for the few episodes he appears in, until his final appearance where he takes Yugi and the others to the Pharaoh's temple. In fact, in the manga, Bobasa is an alternate identity of Shadi/Hassan.
  • Depending on the Artist: The first two seasons of the second series anime follow Kazuki Takahashi's manga style pretty well, but the various animators start to show their specific styles around the end of the Battle City finals and into non-manga material. This causes discrepancies between the proportions of the characters; for example, the ever-changing size of Yugi's hair. Some artists, like Kagami Takahiro, are consistent with art and animation. Others, like Kawaguchi Keiichirou, are very Off Model.
  • Determined Expression: A staple of Kaiba, to the point where many a fanfic has waxed eloquent over his "icy death glare". Yami Yugi usually prefers speech-making, but has been known to utilize this effectively as well. Joey doesn't do this as frequently as Kaiba, but when he does, a crowning moment of awesome will ensue.
  • Detonation Moon: Yugi has Giant Soldier of Stone destroy his own Full Moon card. It recedes the ocean from the field, beaching Mako/Kajiki's monsters. Years later it would be ascended into its own card.
  • Deus ex Machina: Whenever one of the heroes is in a hopeless situation, the solution is often them drawing a card we've never seen or heard of (and in many case never will again) that provides the perfect solution. Also known as "believe in the heart of the cards".
  • Deus Exit Machina: The three Egyptian God cards, which Yugi worked hard to acquire in Seasons 2 and 3, are stolen in the very first episode of Season 4 by the local Quirky Miniboss Squad and are drained of their power. Yugi manages to regain them in time for the final battle, but up until then only one God is used, just once right after the theft, and then by a friggin' Mook, who should have been unworthy of/too weak to use it, but gets to anyway because he has a power that allows him to have limited control over it.
  • Did Do The Research: Though occasionally the exact details are fuddled, the mythological concepts explored throughout the franchise show that someone obviously did their homework.
  • Dub-Induced Plot Hole: In Season 2 Isis/Ishizu arrives in Domino City via plane. A Domino museum official welcomes her "to America." This is contradicted in Season 4 when the protagonists actually travel overseas to America to investigate the local Filler Villains.
    • In the dub, they are are said to be flying to California. It is perfectly reasonable for people living near the East Coast to need to take a plane to California.
    • A creeping one happens as far back as Episode 2. Joey is motivated to play Duel Monsters to win an upcoming district tournament when he sees the prize is 3,000,000 yen (For reasons not revealed until the next episode). And so he trains under Solomon/Granpa to get better. After that scene it flashes forward an estimated few days to weeks where he ends up losing in the quarter-finals. In the Dub he wants to train to get better at the game for no reason other than to get better, and all mention of his entrance in the District Tournament disappears if for no reason other than to make him look more hopeless at the start of the series. This ends up causing a bit of confusion when Season 3 rolls around and he ends up comatose after his duel with Marik, where during his time in the coma he relives his memories from the tournament showing how he lost in the quarter-finals to show how much stronger he's become since then, and fighting subconsciously to fulfill his promise and face Yugi again. However, in the Dub he's just straight-up dreaming and he is deliberately told this by Yugi in the dream, kind of killing the tension and giving the idea he's just going about his life without a care in the world, oblivious to what he was doing before.
    • The English dub actually fixed some plot holes from the original anime:
      • In the original, Yugi says that duelists were only allowed to have exactly 40 cards on hand. Yugi lost 3 Exodia cards and gave Time Wizard to Joey, meaning that his deck had 36 cards. This line is absent from the English dub.
      • In the original version, Joey tells the Rare Hunter that "only Yugi has Exodia", despite the fact that Yugi lost the Exodia cards in duelist kingdom. In the dub, Joey is just says that Exodia is rare.
      • In English dub, a "moan" is added when Pegasus' corpse is shown, explaining how he is alive for season 4 and 5.
  • Dub Name Change: The dub was done by 4Kids Entertainment, after all. Jonouchi becomes "Joey," Anzu becomes "Tea," Honda becomes "Tristan," Shizuka becomes "Serenity," Mai's last name changes from Kujaku to Valentine, Dinosaur Ryuzaki becomes "Rex Raptor," etc. Some card names were also changed, for example, Black Magician being renamed to Dark Magician (and the same for the card's female counterpart, Black Magician Girl to Dark Magician Girl) and its corresponding attack card, Black Magic, being renamed to Dark Magic Attack.
  • invoked Dude, Not Funny!:
    • Anzu replies with this when Jonouchi jokingly suggests that Kaiba died after his soul was stolen by Pegasus at the end of the Duelist Kingdom arc.
    • After everyone gets off of Alcatraz Island, Kaiba tells everyone that he knew the blimp's engines weren't working. All the while, he was smirking when he said that, meaning he thought that it was funny. Jonouchi, reasonably, gets mad at him for almost letting them die.
  • Dude, Where's My Respect?:
    • Joey says this almost word-for-word upon hearing that Kaiba refused to invite him into the Battle City tournament even though he was the runner-up in Duelist Kingdom.
    • Lampshaded in Duel Academy's school pledge.
  • Duels Decide Everything: Apparently, even before Yami Yugi Duel Monsters games decided a few inane things, but post-Season 2 pretty much every Duel could be a Shadow Game or a Dangerous Bet.
  • Early Installment Weirdness: Duelist Kingdom uses completely different rules (if there even are any, with the series often functioning with New Rules as the Plot Demands) than later arcs, playing more like an RPG than a trading card game. There are too many to list, but examples include Yugi being able to "beach" Mako's sea creatures, being able to target separate parts of monsters, attacks being able to "miss," etc. The rules of the Duel Monsters TCG weren't really made yet when Duelist Kingdom happened in the manga, which the anime mostly follows.
    • Later seasons bring the rules in closer with the real-life card game. Before Duelist Kingdom, the source material manga doesn't have as many instances of the Duel Monsters game, and overall, the entire manga in general is much darker; for example, Ironic Hell as the consequence for whoever loses Dark Yugi's Shadow Games or any of the villains. In comparison, this anime adaptation and its spin-offs are much lighter.
    • Even the cards are this. In this series the cards are mostly inclined towards the horror genre, religion and mythology, especially but not restricted to Ancient Egypt. Later series since GX have a "futuristic and dragons theme" for the cards and never looked back since.
  • Earworm: The Japanese openings and endings. The biggest offender is Rakuen from season 3.
    • Shuffle and Overlap count as big offenders too - the former's very catchy and the latter is just damn awesome.
  • Evil Sounds Deep: Played straight with Yugi/Yami Yugi and Marik/Yami Marik. Both played straight and subverted by Bakura/Yami Bakura in the original Japanese. Yami Bakura does have a deeper voice than Bakura, but both have a high-pitched squeaky effeminate voice. Played straight in the dub.
    • Also used with Marik when his Superpowered Evil Side isn't in control. When he's pretending to be a protagonist, and after his Heel–Face Turn, his voice is higher and softer.
    • Also inverted with Noah; when he's a villain, his voice is high-pitched and bratty, but when he makes his Heel–Face Turn, it gets lower and more mature.
  • Exactly What It Says on the Tin: A lot of the cards, like "Red-Eyes Black Dragon," "Man-Eating Treasure Chest," and "Dark Magician," just to name a few.
  • Expy: At one point, Yugi and Tea go up against a guy (nick)named Johnny Steps at a Dance Dance Revolution clone. Doubly hilarious seeing as DDR is also put out by Konami.
  • Extra Eyes: Pegasus' Thousand-Eyes Restrict somehow has, as the name implies, one-thousand eyes covering its body.
  • Face Framed in Shadow: Every major villain has this going on for them, especially friends who have been made Brainwashed and Crazy.
    • Also used to somewhat hide Yami Yugi's identity, first in Season 0 when Tea wonders who saved her and again in Season 2 for Kaiba during Ishizu's Millennium Necklace visions. The shadow even follows him as he stands up.
  • Fade Around the Eyes: Marik does this at the end of his first in-person appearance, as he sends out the Rare Hunters. When he does, he glares at the screen as it fades to black around his Purple Eyes.
  • Failure Is the Only Option: Even though they're playing a card game, of which the consequence of losing would normally only be a hit to the loser's ego (if that), the main characters are frequently involved in "shadow duels" where the gist is losing = death, making Failure Is the Only Option (for the villains)/Boring Invincible Hero played straight. This applies to all Yu-Gi-Oh anime, not just this one.
  • First Episode Spoiler: Added in to the dub, the second episode has Pegasus revealing to Yugi that Duel Monsters is based on magical duels performed in Ancient Egypt; an important fact to be sure, but in the original version it wasn't revealed until the next arc entirely.
  • Five-Bad Band: The Big Five. In the DOMA/Orichalcos filler arc, there's Dartz and his men (if you include Mai). You could also make a case for Pegasus and his Player Killers if you wanted. For the DOMA Arc:
  • Five-Man Band
  • Flanderization:
    • Kaiba's rude tendencies in the dub. Compare:
      dub!Kaiba: Mokuba, make sure Wheeler is late.
      Japanese!Kaiba: Mokuba, please show them around.
      dub!Kaiba: Wait and see, you geeks haven't seen the last of me. [Paraphrased]
      Japanese!Kaiba:''' One day, I will invite you [to Kaiba Land].
    • Bakura, (lampshaded in the Abridged Series too):
      Marik: My name is Marik.
      Japanese!Bakura: I'm Bakura.
      dub!Bakura: I don't care.
  • Freudian Excuse:
    • The whole reason Thief King Bakura tried to take over the world in the first place is because he saw the Kul Elna massacre first-hand and was its only survivor.
      • And yet, the Bakura who wanted to rule the world actually isn't Thief King Bakura, but instead Zorc taking over Bakura's body. Nothing makes sense.
      • It's worth noting that in the manga, it's understood that Dark Bakura is the Thief King whose soul was consumed by the essence of Zorc Necophades.
    • Also Seto, arguably, given his orphaned childhood and history with Gozaburo.
    • Marik's Superpowered Evil Side developed as a result of his unwilling upbringing as a tomb keeper (with some help from the Millennium Rod), which involved isolation, abuse, and an excruciatingly painful initiation ritual.
  • Friendless Background: Yugi had one of these before finishing the puzzle.
  • Friendship Moment: Given the main theme of the series, there's bound to be plenty of this.
    • A really touching one in particular is between Yami and Yugi. After Yugi is discharged from the hospital after his duel with Bandit Keith, he becomes uncharacteristically quiet and gloomy. Even though he knows something is troubling him, Yami decides to patiently wait for Yugi to voice his concerns, and only then he realizes that Yugi has been afraid of losing him after his duel with Keith, which made him realize that Yami might have to leave someday. So, Yami, knowing full well that he would have to leave his side in the future, tells him that despite what he had to do, he wanted to be with him forever. And Yugi, despite realizing that Yami would really have to leave, replies that he also wished for them to be together, and that even if the Pharaoh didn't get his memory back, he and Yugi would make new memories together.
  • Frothy Mugs of Water:
    • In the dub, Pegasus is clearly drinking wine, but he refers to it as grape juice or fruit punch. Given Pegasus's character, though, this holds up better than most.
    • Averted in The Movie, wherein Pegasus wakes up from what he thinks is an Acid Reflux Nightmare and says "No more white wine spritzers before bed", and the next day, is drinking a red wine spritzer. This actually isn't too out of character for him, either.
  • Fun Size: Yugi Mutoh is a shorter version of Yami with fewer blond streaks in his hair.
  • Geo Effects: Field Power Bonus. Emphasized very much earlier in the card game, but dies out to only Field Spell Cards by the Duelist Kingdom finals.
  • Genki Girl: Mana, whose introduction consists of her jumping out of a vase to glomp the pharaoh.
  • Get a Hold of Yourself, Man!: Yami gets one of these from Joey in the form of a punch to the face.
  • Girls Love Stuffed Animals: Rebecca has a teddy bear that she regularly speaks to in her first appearance. By the time she reappears in the Doma arc, however, she's ditched the "cutesy little girl" angle, and Teddy is nowhere to be seen.
  • Gotta Catch 'Em All: Averted — even though the show is largely about a collectible card game, the actual collection aspect is barely seen, with most characters pulling new cards out of nowhere during duels rather than explicitly obtaining them through booster packs or trades.
    • Yugi's grandpa owns a trading card/game shop and Kaiba is rich. The Battle City season has the rule that a loser must hand over their rarest card after they lose, with Jonouchi's (formerly Dinosaur Ryuzaki/Rex Raptor's) Red Eyes Black Dragon being a significant plot point. Jonouchi often uses cards he received from winning, such as Jinzo.
    • Possibly an Aversion of a Subversion (maybe?). Unlike in real life, where serious players usually have 2 or more decks at once for a Collectable Card Game, all the characters in Yu-Gi-Oh! have only 1 deck that they retool constantly. That being said, those retoolings might as well count as entirely separate decks unto themselves. Mai Kujaku/Valentine, who switches from Harpies to Amazons from Duelist Kingdom to Battle City, is probably the closest-to-real-life player in that she has an entirely new deck, though she still includes her Harpies. Then again, can you blame Kaiba for wanting Blue-Eyes in every deck?
    • The Pharaoh does, at one point, buy a booster pack which contains a card seen in later duels. While on a not-date with Anzu. Who notes grimly that it's the happiest he's been thus far all day.
    • Played straight on the part of the evil version of Bakura, who wants to collect all the Millennium Items so he can rule the world (dub) or obtain the power of darkness (Japanese anime and manga).
  • Graceful Loser: Pegasus, who after being thoroughly trounced by Yami, fulfills his promise by releasing the souls trapped in cards and stops causing problems for the protagonists.
    • Averted with Kaiba though.
  • Grade School CEO: Seto Kaiba won Kaiba Corp from his step-dad when he was a teenager, and turned it from a weapons-manufacturer to a gaming company.
  • Gratuitous English:
    • Pegasus in the Japanese anime.
      Pegasus: UNBELIEVABLE! Kore wa NIGHTMARE! Bad dream!
    • Most of the cards have names in Gratuitous English too; Red-Eyes Black Dragon and Blue-Eyes White Dragon are completely unchanged from the Japanese version.
    • Also in the Japanese anime, terms like "duel(ist)," "player," "direct attack," "Duel Disk," "deck," "card," "Monster/Magic/Trap Card," "turn," "draw," and the different phases of the duel (i.e., Draw Phase, Standby Phase, Main Phase 1, Battle Phase, Main Phase 2 and End Phase) are said in English. "Reverse card, open!" is another commonly-heard English phrase in the Japanese anime.
    • Rebecca also speaks a lot of English. Her very first line in the series is "Hello, my name is Rebecca." Both Pegasus and Rebecca are American, so it stands to reason that they would speak English. However, Bandit Keith, who is also American, doesn't speak one word of English, strangely enough.
    • The Egyptian God Cards have the names written on them in English in the Japanese version of the anime (being the only cards that do). The names written on them are completely different from what they're called in both Japanese and English - THE SUN OF GOD DRAGON (Ra no Yokushinryū/The Winged Dragon of Ra), THE GOD OF OBELISK (Obelisk no Kyoshinhei/Obelisk the Tormentor) and SAINT DRAGON - THE GOD OF OSIRIS (Osiris no Tenkūryū/Slifer the Sky Dragon).
  • Hacked by a Pirate: Pegasus does this by showing his favorite cartoon rabbit character when he counter-hacks Kaiba trying to hack into his system.
  • Ham-to-Ham Combat: Although many duels feel this way, the Yugi vs. Kaiba ones are the greatest examples. At some points it feels like their voice actors are competing to see who can do the most over-the-top performance and still keep it in the final cut.
    • The Yami Marik vs. Yami Bakura duel is a fabulous example of this, especially since most of their dialogue consists of them making very enthusiastic death threats to each other.
  • Healthcare Motivation: The reason Joey/Jounouchi participates in the Duelist Kingdom tournament is to use the prize money to pay for his sister to have eye surgery.
  • Heroic Willpower: Joey/Jonouchi's main strength is this, as he displays in various ways in his confrontations with Marik.
  • Heterosexual Life-Partners: Yugi and Yami Yugi, Joey and Tristan.
    • Yugi and Joey are like this as well, with Yugi calling Joey his best friend. It gets to the point that, when Joey is brainwashed and they're forced to duel, Yugi does his best to help Joey and, when Yugi thinks he's about to die, he tells Joey that he loves him.
  • Homage: The card game was originally intended as an homage to Magic: The Gathering, of which Takahashi is a fan.
  • Hostage for MacGuffin: So much so (especially with Kaiba's little brother Mokuba) that LittleKuriboh's Gag Dub of the show has an entire running gag built around it.
  • Hot for Teacher: Subject to interpretation, but Mana in the anime is very devoted to Mahad. Her goal through season five is to become a better magician, both because it's his will for her and because she wants to be able to summon and see his spirit. "Prince can summon him from the tablet, right? Please! Bring me and Master together!" She talks or thinks about him in every scene, and her other goal is to always be with and protect him... which she succeeded in, if the existence of the Black Magician Girl in modern times is any indication. One must note that the subtext is only present in the Japanese version — 4Kids rewrote her dialogue and character entirely until she and Mahad have nothing but a classroom relationship.
  • Hot-Blooded:
    • Jounouchi/Joey is easily riled up and is the loudest character in the bunch.
    • Bakura, especially as Thief King Bakura in season five. He makes the most arrogant pronoun ever (Ore-sama) sound good in constant use, and... "ORE-SAMA NO TURN!" Sort of lampshaded in the Japanese anime, wherein during a duel between Yami Bakura and Yami Marik, Bakura shouts "Ore-sama no turn!" and Marik replies "You're no ore-sama."
  • Hybrid Overkill Avoidance: Usually averted, but played straight in the first tournament when Yugi fuses his Mammoth Graveyard to Kaiba's Blue Eyes Ultimate Dragon to slowly weaken it.
  • Idiot Ball: In the first ever duel between Joey and Kaiba, Joey's entire strategy could be summed up as "summon monster to attack." He apparently forgets that his monsters aren't nearly strong enough to beat Kaiba's, but he just keeps summoning them and having them attack Kaiba's monsters, so they're destroyed instantly and cost him points. He never shows this level of stupidity in any duel before or after this. Justified in that he is unfamiliar with the Duel Disk technology and doesn't know how to set monsters in defense mode.note 
    • Yugi's largest Idiot Ball is when, in his duel against Pegasus, he summons Celtic Guardian to attack Toon Mermaid, hoping to destroy them both. If Toon Mermaid merely dodges the attack, as Toon Blue-Eyes did before, Pegasus can attack Celtic Guardian with Toon Summoned Skull, winning the duel. But then, Yugi is under a considerable amount of stress.
    • Here's a drinking game—watch the series and take a drink every time a duelist makes a move and doesn't notice the opponent has countered it until it's too late. Blame Rule of Drama, since apparently if it'll make for a dramatic twist then duelists can activate cards without announcing such (e.g., Isis activating Blast Held By A Tribute to "secretly" infect Obelisk without saying so). However, in the real card game every play of a card must be announced and your opponent given a chance to respond if they are able, and if they choose not to they don't get to just rewind and change their minds once you begin to make another move.
    • From the Waking The Dragons arc, Yami playing the Seal of Orichalcos that Raphael gave him in order to avoid losing the duel. There was literally nothing at stake until he played that card, since the "loser loses their soul" condition of the duels in this arc only applies after the Seal has been played. He could have just taken the loss and walked away to continue his fight against Dartz's organization, but no, he just had to win. Of course, this may well have been the "evil" that Raphael said was in him in the first place.
  • If I Had a Nickel:
    Seto: If I had a dime for every time you said the word "destiny," I'd be even richer.
  • I Have Your Wife: Used by various villains throughout the series. The target is usually Mokuba, who is kidnapped a grand total of 15 times.
  • I Just Want to Have Friends: When Yugi first completes the puzzle, he makes a wish on it to have some true friends.
  • "I Know You're in There Somewhere" Fight: Yugi has one of these with Joey/Jounouchi when Marik takes control of him. Jounouchi has one with Mai in Season 4, the latter having to lose his soul just to snap Mai back to normal.
  • In the End, You Are on Your Own: Seto Kaiba believes in this. He doesn't have any friends, and he doesn't even want any. He thinks depending on no one but yourself is for the strong. From the looks of it, though, it's the "monsters" of Wrath and Envy talking.
  • Inadequate Inheritor: In the Virtual World arc, Gozaburo says he considers Seto this.
  • Indy Escape: Subverted during Duelist Kingdom. The boulder in question was just a balloon with a speaker in it.
  • Ineffectual Loner: Seto Kaiba. As far as he's concerned, the only option is victory. And the only allies...are enemies.
  • Informed Ability:
    • The Kaiba brothers. For all of their supposed awesome skill at playing their favorite games, they tend to fall for very simple ruses. Mokuba and Yugi's Capsule Monsters match is an especially blatant example.
    • There's a reason why we never see Yugi and Seto play chess. King of games or not, you can't use the heart of the chess piece to win a game. And there are no power-ups (other than promoting pawns, which isn't too hard to see coming) or convenient special abilities.
    • Rex Raptor and Weevil Underwood were in a tournament championship facing each other right before the Duelist Kingdom arc. Yet, from then on out they never pose much of a threat to, well, pretty much anyone, effectively becoming Those Two Butt Monkeys who sure don't look like champions of any level of tournament.
      • Rex is an unfortunate case. Of all the duels he loses in the canon arcs, almost all of them are against opponents who are willing to cheat or against Joey (who wins by dumb luck). Admittedly, we don't see anything to suggest that Weevil cheated in their first duel, but considering that it is Weevil who throws Yugi's cards into the ocean it wouldn't be too surprising. (He also doesn't cheat against Yugi in the original Japanese version; the reason he knows about the new rules ahead of time is because Pegasus told him about them as a prize for winning the Regional Championship.)
      • The same could be said of Weevil/Haga really. Other than that, Weevil went up against Yugi/Yami Yugi twice and did very well both times. Certainly Weevil cheats but he's still shown to have great skill. The cheating only seems to serve as a supplement to his own abilities, or because he enjoys it. Other than Joey, Weevil's only ever lost to exceedingly great duelists. The main reason he becomes a joke character is because he's a Smug Snake who Can't Catch Up as far as powerful cards go.
  • Insane Troll Logic: In the anime, Ryuji Otogi/Duke Devlin's evil plan is made up of some pretty epic idiocy. He plans to prove that Yugi must have cheated in his duel with Pegasus... by cheating in his duel with Yugi, by challenging him to a game of Duke's own creation and refusing to explain the rules. Not just cheating, either, but cheating openly and bragging about it. Sure, if he wins he would still get half of what he wanted (forcing Yugi to give up dueling), but even then all he would manage to prove to the world is that he is a liar who can't win without cheating, not Yugi. If his plan works he would lose all credibility, and probably all of his customers and fans, too. Manga Ryuji averts this; not only was his plan more sensible, most of it wasn't even his plan, it was his (legitimately insane) father's.
  • Instant Awesome, Just Add Dragons: The most powerful cards in the game are dragons, and it was carried over to the sequels. The villain in the crossover movie with GX and 5DS summons nothing but dragons, to show how superior they are to the audience. Even Kaiba (the most dragon-obsessed guy in the series) has some variety in his deck.
  • Insult to Rocks: "You know, I'm not quite sure what to call you. I was thinking about 'monster'... but I wouldn't want to insult the cards."
  • Intergenerational Friendship: Big time, between Yugi and the Pharaoh/Yami Yugi.
  • Invincible Incompetent: Katsuya Jonouchi (Joey Wheeler) perpetually comes from behind to win. Granted, everyone does this, but Joey never seems to be picked as a favorite to win anything, despite several finals showings.
  • Invincible Villain: Filler Villain Dartz really pushes it. He's a 10 000 year old man who was around 5000 years before the Millennium Items were created, was King of Atlantis, has the Oricalchos, whose ability is "whatever the plot needs it to be", owns parts of every company on the planet, can spy on the entire cast with no problem, buys out KaibaCorp with ease, has one of his henchmen defeat previous Big Bad Pegasus without a problem, brainwashes Mai into serving him, possesses a monster with infinite attack, and can take on the Pharoah and Kaiba at the same time. And to top it all off, he gets redeemed and is reunited with his family at the end, giving him everything he wanted in the first place. In addition to this, he never apologises, neither in the original nor the English dub, and is acknowledged by the others as being a 'good ruler after all'note .
  • Ironic Echo: In season one, Kaiba threatens that he'll fall from the castle's battlement if Yugi wins the duel, so Yugi forfeits in fear that Yami would finish Kaiba off. In season five, Yugi again faces the decision of defeating his opponent in a duel to kill him. In this case, the opponent is Yami. Yugi hesitates on finishing the duel, but carries it out, as this time, the reason is to send Yami to the afterlife.
  • I Will Show You X: When Tristan has an open crush on Joey's sister Serenity, which Joey is none too pleased about. At one point in the English dub, Tristan talks about how he's going to visit Serenity (read:hit on her) in the hospital, to which Joey responds "I'll send you to the hospital!"
  • Jerkass:
    • Kaiba is an Ineffectual Loner with a lot of money and a superiority complex.
    • Bandit Keith is a bigger one. He and his mooks trap Yugi and the gang in a cave, and he also steals Jounouchi's Glory of the King's Hand card while the latter is sleeping.
  • Joker Jury: In the dub version of the Virtual World arc, Johnson, whose Deckmaster and appearance is that of Judge Man, claims he is putting Joey on trial for gambling.
    • He then proceeds to make every trial joke imaginable.
  • Karma Houdini: Ushio, compared to the original manga. In the anime, nothing is really mentioned on what happened to him after the flashback to the scene where he beat Yugi and his friends up. The dub does add in a very quick line where school authorities found out about him and properly punished him, but the original version never says anything beyond that, arguably implying he got off completely scot-free for what he did.
  • Kick the Dog: During a duel using the Orichalcos, Weevil makes the mistake of claiming he has Yugi's soul in his hand, then tearing it in front of Dark Yugi (which was really a normal bug monster card, making it much worse as he was using it as a way to mess with the already broken duelist). This does not end well for Weevil.
  • King of Games: Trope Namer; it's the title the main protagonist has for his mastery of gaming in the original manga. He has some shades of this in the anime, but mostly shows interest in Duel Monsters.
  • King of Thieves: Thief King Bakura, Ryo Bakura's past self. His "King of Thieves" title comes from the "weight" of what he steals. Like other monsters' powers with his "ka", The Diabound, and because he seeks (and even got all) the millennium items, until he was imprisoned into one of them, that is.
  • Knight Templar Parent: This is about the nicest description possible for the way Gozaburo Kaiba raised his children, although it was probably really just the company he was worried about.
  • Know When to Fold 'Em: Mai does this with Tea at Duelist Kingdom, and later in the Duelist Kingdom finals when facing Yugi. Both times, she says she doesn't have a monster strong enough to take down what the opponent has on the field.
  • Lethal Joke Item: Some cards are weak or nearly-useless on their own but devastating in the right circumstance. For example, the Ojamas, three monsters with 0 Attack, have a support card that can wipe out all opposing monsters, spells, and traps, and they can fuse into a potent defensive wall. Or the four Parodius monsters, each with minimal ATK and DEF, but which can combine with one another as Union Cards to have absurd ATK and DEF.
    • Baby Dragon is the earliest example. It starts with only 1200 ATK, easily destroyed, but with Time Wizard, it becomes Thousand Dragon, with 2400 ATK, stronger than most cards in the game at that point.
  • Let's Fight Like Gentlemen: They settle every conceivable difference via a collectible card game, for cryin' out loud!
  • Letting the Air Out of the Band: Happens during Yugi's final duel with Marik. He uses Obelisk's ability to destroy Ra. The triumphant music starts playing and it seems he won, only for the smoke to clear, revealing Ra to still be on the field, at which point this trope plays out.
  • Lighter and Softer: Compared to the manga.
  • Lovely Assistant: Stage Magician Arkana was in love with his Lovely Assistant, Catherine, and they were engaged—before his disfiguring accident. Although Catherine still loved him, Arkana pushed her away. He later regretted his choice and fell in with Marik when Marik promised he could restore Catherine to Arkana.
  • Lull Destruction: Compare the Dub to the Japanese version. Some scenes have added dialogue, especially if in the original the characters are silent.
  • Magical Eye: Pegasus' Millennium Eye, possessing the power to read minds and probably do other sinister things. According to Word of God, it also brainwashed Pegasus into creating Duel Monsters, making it a literal evil eye.
  • The Magic Poker Equation: Arguably Yu-Gi-Oh's central trope, where "important" players have an uncanny ability to draw the only card that will help them. Some adaptations present that drawing is a matter of skill, determination and faith, and the duelists are aware of this fact.
    • Episodes 41 and 42, while an otherwise unremarkable pair of filler episodes, shows Yugi and Rebecca's duel, which apparently goes exactly like a duel their grandfathers played decades earlier, turn for turn, card for card.
    • Lampshaded in the anime arc Waking the Dragons, along with Plot Armor, in the English dub by Rex Raptor/Dinosaur Ryuzaki, when he and Weevil Underwood/Insector Haga witness Yugi use the Eye of Timaeus with Dark Magician Girl. He mentions how Yugi and company tend to draw the cards they need at the right moment, but he and Weevil don't.
  • Mark of the Beast:
  • Meaningful Name: Happens for a couple of characters, particularly the (ancient) Egyptian ones:
    • If Marik's name were transliterated differently when moving into the English dub, it would be the Arabic name Malik (or "ملك" in Arabic), which is based on the words for "king" or "possessor" in the Arabic language. Incidentally, Marik possesses several people and wants to be the pharaoh/king of Egypt/the world as a Big Bad.
    • Also Odion's name in the Japanese version is Rashid (or "راشد"), meaning "rightly guided" in Arabic. Odion/Rashid is Marik/Malik's older adopted brother and serves as one of his two Morality Pets in the series.
    • Shadi's name is only a phoneme different from the ancient Egyptian word shabti. Shabti are figurines placed in tombs among funerary goods so they can be servants to the tomb's owner in the afterlife. Using representative figurines replaced killing actual servants for this sole purpose. Shadi guards the Millennium Items' original resting place and turns out to be just a ghost since Yami Bakura killed him 5000 years ago when he was one of Atem's priests. And like Malik's and Rashid's names, the name "Shadi" is also Arabic in origin, reflecting that all these characters come from modern Egypt where Arabic is the official language.
    • There's also Ishizu, named after the ancient Egyptian goddess Isis. Isis is the queen of magic, dedicated wife to her murdered and undead husband Osiris, and honored for being a good mother to her son Horus. Ishizu is a Mysterious Waif of a character who can see the future using her Millennium Necklace. One of her major goals is to stop her Face-Heel Turned younger brother Marik from being villainous. She is also another one of Marik's Morality Pets.
    • "Yugi" means "game."
      • Yami means dark or shadow, which means that "Yami Yugi" means "Shadow Game."
    • Oh, also, the whole Yu Jou thing. Take the initial syllables of Yugi and Jounouchi's first names and you get the Japanese word for "friendship." (Which manifests itself in real life as the "Yu Jo Friendship" card.)
    • And the fact that Seto Kaiba, the most dragon-obsessed guy in the cast's surname translates to "sea dragon." On a related note, the same guy's first name translates to "shallow man."
    • There's an even weirder couple of meanings behind his name. "Seto" is basically the Japanese pronunciation of "Set." Combine this with Yugi's name ("Game", "Set", Match) for one meaning, but for the other, Set was the Egyptian desert god, a completely appropriate name for a high-ranking ancient Egyptian priest.
    • Possibly unintentional, but the English surnames for Jonouchi, Anzu and Honda are all occupations: Wheeler, Gardner and Taylor.
    • Yami's real name, Atem, is a variation on Atum, as in Atum-Ra: the creator god, the god of the sun, the first king of the gods, the first pharaoh, etc. Oh, and Atum apparently had a Winged Dragon, too.
  • Mind-Control Eyes: People under Marik's control have their eyes drawn without pupils.
  • Mind Screw: The Memory World arc is a mild version. In general, things make sense and you can follow what's going on, but some really bizarre stuff happens too. The anime-only content/changes doesn't really help things.
  • Mondegreen: No, the dub theme is not misspelling Yami as Yamu, it is actually Your Move.
  • Morality Pet: Mokuba Kaiba is one for his brother Seto. Odion and Ishizu Ishtar are the same for their master/brother Marik.
  • Ms. Fanservice: Mai Valentine and Dark Magician Girl.
  • Multicolored Hair: Yugi has black and purple spiky hair with freestanding streaks of blond in it. His grandfather had the exact same hair when he was younger, and although it's now gray it retains the same shape.

    N - Z 
  • Necromantic: Pegasus got his Start of Darkness after his beloved wife Cyndia/Cecilia passed away and he vowed to bring her back.
  • Never Say "Die": In the English dub, at least.
    • Except for Episode 8 where Kaiba tells Pegasus's men he'd rather die than be captured and promptly leaps to his supposed death, which is mentioned in the next episode where Yugi duels Kaiba's "corpse."
    • Also averted in Episode 13, when Tristan is first sent to the Graveyard.
      Tristan: According to this tombstone, I'm dead!
    • Pegasus plots Kaiba's death and says for him to have an accident... which actually works as Getting Crap Past the Radar, since that's what a Corrupt Corporate Executive (or a member of The Mafia) would do to a business rival.
  • New Powers as the Plot Demands: Frequently, characters reveal to have cards in their decks that they never used before (and never will use again), but which help them win the current duel.
  • New Rules as the Plot Demands:
    • Duelist Kingdom is this writ large. Some make at least a bit of sense, like flying monsters having an advantage over land-based monsters, or machine monsters rusting due to a mist over the field. Others just plain have no basis in fact at all, most prominently the infamous Catapult Turtle move Yugi uses to defeat Panik. However, Duelist Kingdom is stated to use custom rules specific to the tournament.
    • Once the rules were written and pinned down in Battle City, this turned into "New Cards As the Plot Demands," with duelists producing cards never before seen at just the right time. Many of these cards exist for Rule of Cool, as there are other pre-existing cards that do the same thing as the new card but don't fit the theme of the duelist's deck. Change of Heart for example has equivalents with Yugi and Kaiba in the forms of Brain Control and Enemy Controller. And lapses of the random new rules still occurred: Jinzo is supposedly immune to Time Wizard's effect due to being made of special metal, for example, and Flute of Summoning Dragon lets both players summon Dragons from their hand if they want.
    • There's also a ton of cards that were created to allow the duelists to draw cards so the writers can keep their hands filled, such as Card of Last Will, Card of Demise, Nibelung's Ring, and especially Card of Sanctity. Kaiba's "Power Balance" in particular is ridiculously overpowered in this regard, requiring the opponent to discard half their hand and then allowing the user to draw the same number of cards discarded, all with no drawbacks. But hey, it added tension to his duel with Yugi so why not? Though it doesn't beg the question why he only uses it once.
    • With 2-on-1 and later 3-on-1 duels throughout the franchise, the rules are never ironclad, sometimes the lone player gets more turns, sometimes more Life Points, or no advantage at all. A few times it seems that the lone player chooses their advantage, which of course is ridiculous. This is particularly blatant in 5Ds where in on 2-on-1 duel, the lone player began with 10 cards in his hand to cover the disadvantage, when his deck theme is based around destroying his own Trap cards to deal a First Turn Kill. No prizes for guessing what he tries to do, and would have succeeded at if not for the predictable debut of cards that negate effect damage.
  • Nietzsche Wannabe: During the duel between Joey and Yugi in the Duelist Kingdom finals, Pegasus's narration, at least in dub town, slips into this. To quote:
    • "Oh, I know you'd like to think that your friendship would be enough to sustain you through any mishap or misfortune, but that's not the way the world works."
    • "... when fate hits you with a cold slap of reality and shows you who's boss. Yes, the world has taught me that only the strong and the ruthless survive."
    • Kaiba is seen reading Nietzche in his first appearance. (In the Japanese, at least.) No better way to paint yourself a villain immediately, aye?
  • No Kill Like Overkill: Numerous times, characters will pointlessly weaken themselves in order to boost their monsters powers or completely clear the field before delivering a final blow so that not only do their opponents life points drop to 0, but all their monsters are gone too - this being in situations where they could save themselves the trouble and just attack outright and win.
    • A prime example is Atem's fight with Weevil, after the latter pretended to destroy Yugi's soul just to get a rise out of the Pharaoh. Atem used a card that let his monster attack directly every time he drew a monster card, and proceeded to pound Weevil again and again, long after his Life Points ran out. He would've kept going too, if Tea hadn't stopped him. Note that this is during a special duel where you actually feel the pain of attacks.
  • Non-Human Undead: In the first tournament, Yugi defeats Kaiba's Blue Eyes Ultimate Dragon by fusing his Mammoth Graveyard into it... which, because both are incompatible types, slowly weakens the resulting fusion and will cause it's eventual death. After this, the rule is never referenced again.
  • Not Disabled In VR: In the Virtual World Filler Arc, Seto Kaiba's adoptive father Gozaburo Kaiba originally had the virtual world created for his biological son Noah after Noah was hit by a car and left permanently disabled.
  • Not Just a Tournament: Virtually every Tournament Arc, to the point where it's commented in-story how refreshing it is to go to a tournament that's only a tournament (it still manages to get hijacked by a villain's scheme, but at least that wasn't in the host's plans).
  • Not Too Dead to Save the Day: Yugi gets help from all his petrified friends and Kaiba) in his head before playing his last turn in the duel against Noah.
  • Obvious Trap: The point of Odion's deck is to focus on laying tons of trap cards and then wait for the opponent to spring them. Thing is, he makes the point to play almost no monsters thereby leaving him wide open to attack except for his traps, which you know will protect him, he's not stupid. Unless you pack an insane amount of spell/trap destruction or run an unorthodox deck theme, you're gonna have to attack him sooner or later, and when you do, he'll be ready to turn it back on you. Joey found this out the hard way.
    • Joey and Mai later learn Marik also plays a lot of traps, which are even more brutal and painful than anything Odion used.
    • Besides the specific duelists, quite often the characters know the opponent has a dangerous trap waiting, but they acknowledge if they want to win they either need to find a way around it, or trigger it and hope they can come back from whatever it does.
  • Offscreen Moment of Awesome: Yugi vs. Jonouchi immediately after Battle City, even if we know Joey won (he was battling Yugi for his Red-Eyes and is shown to have gotten it back). Both mediums skip this.
  • Panty Shot: Joey and Tristan randomly lifting up Tea's skirt in class and yelling "Panty tank!"
    • Also in Season 0, Joey uses a Yo-Yo to accidentally cause a dangerous flurry of wind toward Anzu and Miho.
  • Parental Abandonment: Mai lost her parents at a young age.
  • Phantom Zone: The Millennium Items each can transport the area immediately surrounding the user (and anyone else in it) to the Shadow Realm, an Alternate Dimension full of the Mons that the Duel Monsters cards are based off of, which can be summoned to fight each other. Alternatively, they can trap a person's mind in the Shadow Realm, leaving their body functioning normally (although from the fact that Jonouchi/Joey breaks out of it and "wakes up," this is implied to be an illusionary spell cast on the victim) or seal their soul into a Soul Jar. (Yami Marik does the former, Pegasus does the latter.)
  • Phantom Zone Picture: Pegasus gives Seto and Mokuba Penalty Games, which involve their souls getting trapped into blank cards. In the anime, this also includes Yugi's grandfather (who gets his soul sealed into a video tape instead in the manga).
  • Pinball Scoring: Every card in the anime does base damage/bonuses/etc in increments of 100; the actual card game has a handful that have 50s.
    • In the Duelist Kingdom season, there are a few duels where damage/bonuses are calculated by percentages of other stats, creating some odd prime numbers. From Battle City on, most all the numbers end in even 0s.
    • Unless you're Marik, in which case you can have attack points that end in —99.
    • A few monsters have ATK or DEF stats that aren't divisible by 50. Castle of Dark Illusions has 920 ATK and 1930 DEF, Reaper of the Cards has 1380 ATK and 1930 DEF, King of Yamimakai has 2000 ATK and 1530 DEF, and Seven-Armed Fiend has 666 ATK and 666 DEF (1000/1000 in the Dub). All but the last are the result of the anime fudging the numbers of the Player Killer of Darkness's monsters so that they have their field power bonus.
  • Plot Tumor: The ultimate one, possibly. Originally, the manga was not about any specific game, much less a single card game. He's supposed to be the King of Games.
    • Arguably lampshaded in The Abridged Series. Yugi is just referred to as "The King Of Card Games".
  • Powered by a Forsaken Child: Creating the Millennium Items required a sacrifice of 99 human lives.
  • Power Levels: Monster cards have them in the form of Attack (ATK) and Defense (DEF) points.
  • Power Makes Your Hair Grow: When Yugi, Bakura, and Marik become possessed by the spirits of the Millennium Items (or in Marik's case his Superpowered Evil Side), their hair gets even more ridiculous than usual.
  • The Power of Friendship: Prior to the card game Plot Tumor, this was going to be the main theme of the series. It still has a fairly strong presence, occasionally to the point of narm.
  • Power Trio
  • Pragmatic Adaptation:
    • The Millennium World arc in the anime is practically an Alternate Universe take on the manga arc rather than an adaptation.
    • The Dungeon Dice Monsters arc (originally called Dragons, Dice & Dungeons in the Japanese manga) is retooled from a plot-relevant arc regarding Yugi's development with no relation to Duel Monsters to a Filler arc whose game has a big influence from the card game (Any plot progress is moved to the next episode about Yugi dueling a possessed Bandit Keith in an Abandoned Warehouse). The same also applies to Duke Devlin. In the manga he is a troubled child who is purposely raised by his father to become a Tyke Bomb, having a Heel–Face Turn because he doesn't hate Yugi as much as his father. In the anime, he is a fanboy of Pegasus who challenges Yugi to a duel because he believes Yugi won by cheating. He changed his ways because he realized that he acted like a dick to Yugi and his friends.
  • Prestigious Player Title: Duel Monsters players are called "Duelists".
  • Protagonist-Centered Morality: Antagonists who use manipulative mind-games are called dishonorable, ones who keep secrets are called liars, ones that go on the defensive are called cowards exposing their own weakness, and ones that use cheap tactics are called cheaters. Of course, when main characters do these things they're simply said to be using intelligent strategy.
  • Psychic Powers: The Millennium Items give their owners a variety of psychic powers, depending on the item. Examples include mind raping, locating and identifying other Millennium Item holders, mind reading, visiting someone's mental landscape, seeing the future, and possessing other people.
    • Dark Bakura uses his Millennium Ring to summon monsters and activate Duel Monsters cards outside of a duel, and sic them on some Mooks. Note that these are anime-only and do not exist in the original manga (where the Millennium Ring's main power is to turn objects into his soul jars).
  • Purple Is the New Black: The Shadow Realm is depicted with some swirls of midnight blue or black but mostly purple.
  • Put on a Bus:
    • Bakura is rarely seen after Duelist Kingdom (not counting the appearances of the spirit of the Ring using his body).
    • Bandit Keith in the anime, who, after losing his duel with Yugi, is never mentioned in the story again.
  • Quest for Identity: The pharaoh is trying to find out who he is and regain his lost memories.
  • Rage Quit: Several times, low-ranking villains will screw the rules and attempt to get their job done directly. This has varying levels of success. This is especially fatal in a Shadow Game, which enforces the rules very strictly and very harshly.
  • Railroading: This is the basic explanation for the series and why the main characters who are losing always seem to pull impossible card effects at just the perfect time.
  • Rapid-Fire Typing: Seto Kaiba often utilizes this whenever he's operating or hacking into a computer.
  • "The Reason You Suck" Speech:
    • Kaiba, most notably, to anyone unfortunate enough to lose to him. Joey is victim to this more often than not.
    • Tea, of all people, turns out to be surprisingly good at these, although she doesn't give them often. She gives one to Kaiba at Duelist Kingdom, although it's more of a "the reason Yugi is better than you" speech. She also lets Johnny Steppes have it for running away when his duel with Yami gets too difficult.
    • After Noah defeats Kaiba and turns him and Mokuba to stone, Yugi gives one to him before he combines his deck with Kaiba's and resumes the duel, but it's similar to the above and saying why Kaiba is better.
  • Recognizable by Sound: In the Virtual World arc, Noah plays Serenity's screams into the tunnel where the rest of the gang are. Joey instantly recognizes it.
  • Redemption Equals Death: Sort of. Noah Kaiba gains a body like he originally wanted, then puts himself back Inside a Computer System to save the others out of guilt. So, not dead but close to it.
  • Reincarnation: Gets rather complicated. It is heavily implied that Yugi is the other half of Atem that didn't get sealed into the puzzle and just sort of floated around until it was born again. Common Epileptic Trees is that Ryou is something similar in regards to the ancient Big Bad Thief King Bakura (who more complicatedly never did a bad deed until being controlled by Zorc, a completely separate being). Seto (with Set) and Ishizu (with Isis) are straighter examples.
    • It's slightly less complicated if you look at the Ancient Egyptian concept of soul. One of the key pieces being the "ren" or name implies Kazuki may have done this on purpose.
      • Heck, it only makes it more complicated. Consider how differently Kaa and Baa in season five behave to their Ancient Egyptian counterparts (and don't even try to come to a strict definition of how the soul parts work in Ancient Egyptian writings). A tip: never sit down with two fans who also like to study Ancient Egypt and ask them whether the series is accurate to Ancient Egyptian mythology or not. They might have matching opinions... or you might end up with a monstrous debate on the topic.
  • Road Sign Reversal: Marik Body Surfing Bandit Keith has set up arrows to lure Yugi into a trap. Yami Bakura flips the arrows around so Yugi's friends can't follow.
  • Rousing Speech: Kaiba gives Yugi his version of one in the Pharaoh's soul room towards the end of the Virtual World arc. It's probably one of the least encouraging rousing speeches ever, especially since his version of, "don't give up," is, "don't screw up or else," but it seemed to do the trick.
  • Rousseau Was Right: Numerous bad guys, including Dartz and his biker henchmen, Marik Ishtar, Pegasus, etc., seem hopelessly callous and evil only to eventually prove to be good at heart, whether by exorcism of an evil side or simple persuasion, usually by Yugi or Pharaoh. Seto Kaiba is also routinely obnoxious and cold yet occasionally proves to have a compassionate side, which is usually related to his love for his little brother Mokuba.
  • Rule of Symbolism: The author intended to have the cards represent the character and personality of their users.
  • Save Sat: In the English dub, Kaiba sets the Industrial Illusions satellite to crash into their mainframe, bringing down their computer defenses and allowing him to access the data at Duelist Kingdom (in the Japanese version, he's just using the satellite to hack into the mainframe.)
  • Screw Destiny:
    • It's revealed in the final arc that one of the Millennium Puzzle's abilities is to "alter fate", which in the context of the Duel Monsters card game allows him to change the card he's going to draw as long as he believes it will happen hard enough, rendering every past example of Yugi drawing the exact card he needed by "Believing in the heart of the cards" more than just good luck.
    • Kaiba manages this rule in the Battle City Arc. Screw Destiny, I have money!
      • He also changes the future itself by following his instincts and sacrificing his ancient god card to summon a Blue Eyes White Dragon to attack and win his game against Isis, whereas her clairvoyance had predicted he would attack with the ancient god and fall victim to the clever damage feedback trap she had set up. He wins the game instead of losing as destiny had foretold.
      • It's actually not instinct. The Millennium Rod reaches out to him, recognizing his soul as its true master, and shows him what to do.
  • Screw the Rules, I Have Money!: The Gag Dub is the Trope Namer.
    • Occurs within the series itself. Kaiba does it, of course. Pegasus, however, even makes special cards that never go into circulation just so that it gives him an advantage.
  • Sealed Evil in a Six Pack:
    • An in-universe fictional example is Exodia, a monster so powerful it takes multiple cards to contain him. The individual pieces are worthless, but a player who reassembles Exodia by getting all five parts in play wins immediately.
    • The Pharaoh was trapped in the Millennium Pendant, which was then broken up into pieces. They were all kept in one place, but putting it back together was a complicated process (which is why it was then renamed the Millennium Puzzle).
  • Self-Made Orphan: Kaiba has a long history of these kind of tropes. Also Marik.
  • Serious Business: Duel Monsters. The universe runs on it. Didn't you know that?
    • Blown to ridiculous proportions in Yu-Gi-Oh! GX, in which it takes an entire navy and air force to deliver a briefcase of rare cards safely to Duel Academy. The Princeton brothers even plan to take over the world through the three pillars of humanity: politics, economics, and Duel Monsters. No joke.
  • Shapeshifter Guilt Trip: Dartz, by projecting the voices and faces of Yugi's soul-stolen friends onto his Mirror Knights, intimidates Yugi into not attacking.
  • Ship Tease: Rebecca kisses Yugi early on in Season 4. Cue Luminescent Blush (and he had an awkward expression on his face before she kissed him).
  • Shout-Out: Both the card game and anime series feature cards based on Konami's Gradius and Mystical Ninja series, and even one that references Metal Gear.
    • First episode, take a look at the shelf that Yugi covers up just as he answers the phone call from Kaiba. Even Super Robot Wars can find its way into a show about a children's card game.
    • Yu-Gi-Oh! references Dragon Ball on three occasions: the first chapter of the manga references Dragonball by name, when Yugi figures having the Millennium Puzzle grant his wish would be similar to collecting the Dragon Balls. Another instance is that a Dragon Ball poster can be seen in Yugi's room during the Battle City arc. Finally, during the KC Grand Championship, Weevil's and Rex's ambush of Fortune Salim and following masquerade a la Totem Pole Trench replicates a similar scene in Dragonball, where Goten and Trunks use a similar tactic to get into a tournament.
    • One of Pegasus's toons sure loves spinning.
    • In a dub-induced case, Mai irritatingly states in "The Gauntlet Is Thrown" that her sleeping conditions on the ship were "Outrageous! Truly, truly outrageous!", in a bizarre nod to Jem.
    • In the dub for episode 95, a movie Marik sees on TV in the outside world has the line, "Sorry Dottie, I'm a loner. A rebel."
    • In Joey's duel with Siegfried he says, "C'mon, big bucks no Whammy's!"
    • In Joey's duel with Solomon/Granpa: "Survey Says!".
    • In episode 213 Joey references the '80s hit song "Walk Like an Egyptian."
  • Social Services Does Not Exist: Story of the Kaiba brothers' life. Also, the manga implies that Bakura lives all alone, though that's more of a self-imposed exile by Bakura because Very Bad Things keep happening to people around him. At the very least, he still writes letters to his dead mother and sister and keeps in contact with his father.
  • Soul Jar: Millennium Ring, Millennium Puzzle, various gaming equipment. Taken literally with Mai in season 2 when she loses to Marik and her mind gets put in an hourglass in the Shadow Realm.
  • Spell My Name with an "S": Marik? Malik? In the Bunkoban series, it's spelled Maric.
    • Logically it should be Malik, which preserves his Meaningful Name from the original Japanese. Not that that ever stops them from changing things.
    • Also Cyndia, although some spell it as Cynthia or Cindia. Then there's her dub name, Cecelia Pegasus, which becomes Cecilia, despite the fact that the proper dub name was shown in episode 40. It gets worse when people assume her original name is Cyndia Crawford, as she does not have a surname in the original.
    • The Big Five consist of Ganzley/Gansley, Crump/Krump, Nezbitt/Nesbitt/Nesbit, Lecter/Lector/Leichter... and Johnson.
  • Split Personality: Not quite, since it's more like another person sharing their body, but it still fits for Yugi and Bakura. Played straight, however, with Marik and Yami Marik.
    • Split-Personality Makeover: How do you know who's in control? Well... just look at the page image.
      • Sometimes averted with Bakura, who often seems to be controlled by the spirit even when he looks like his nice self, which the audience usually finds out mere seconds later. Lampshaded by a close-up focusing on the two front locks of hair moving into a more upright position when the spirit reveals himself to be in control before his duel with Yugi in the Battle City finals.
  • Story Arc: Duelist Kingdom, Legendary Heroes, Battle City, Noah's Virtual World, Battle City Finals, Doma, the Kaiba Corp Grand Prix, and Millennium World, with a Myth Arc spanning all of these arcs.
  • Stronger with Age: Some monsters, like Baby Dragon and Dark Magician, gain stronger forms when they age with Time Wizard's effect. Others, like the Harpie Ladies and Red-Eyes Black Dragon, become decrepit or even fossilized and are correspondingly weaker.
  • Straw Nihilist: "Weapons will not disappear and humans will not stop fighting. Thus, this world might as well be destroyed." — Amelda in episode 166
  • Sudden Sequel Heel Syndrome: Season 4 turns Mai Valentine into an angst-ridden member of a villainous biker gang. It turns out she was tricked into Heel–Face Brainwashing by Dartz.
  • Suggestive Collision: Happens to Joey and Mai in the episode "Lights, Camera, Duel." Played with, though, in that Mai fell on top of him because he was catching her as she fell from a dangerous height—and instead of going for the pervert-slap, Mai thanks him for saving her and calls him an "action hero."
  • Sunglasses at Night: Bandit Keith wears his sunglasses even in a dark cave.
  • Superpowered Evil Side: Various characters' Yami versions, including the early appearances of Yami Yugi, who was more like The Unfettered.
  • Synchronization: Between the duelists and their cards, to some extent. Showcased when Yugi's grandfather Sugoroku actually has a heart attack when he loses.
  • Take Over the World: Both Marik and Yami Bakura want to do this by usurping the pharaoh position from Yami Yugi, mostly as revenge for personal beefs they have with him.
    • This is further complicated by Zorc's entanglement with Bakura, as Zorc has no beef with Yami, but only uses Bakura's.
    • Averted by both Marik/Yami Marik and Zorc in the Japanese versions. Marik merely wants to torment the Pharaoh's spirit as part of revenge and Yami Marik wishes to torture and kill every living thing on the planet. Zorc is just an evil demon fueled by the rage of the people sacrificed to create him, making him want to destroy everything. Even Yami Bakura's motives are unclear and don't really seem to involve wanting to take over the world in the Japanese version. It eventually becomes clear that he really just seemed to subconsciously desire to collect the Items throughout the manga so he can revive Zorc.
  • Taking the Bullet:
    • Kisara dies to save Seto.
    • Earlier in the series, Yami saves Mai and Joey from Marik's Winged Dragon Of Ra by diving in front of a fireball and blocking it with his body until it dissipates. He promptly collapses.
  • The Tape Knew You Would Say That: In episode two of the anime, where Pegasus contacts the protagonist. Granted, it's less so a tape and more of an enchanted two way face cam... thing.
  • Tarot Motifs: Inevitable, considering the series-wide obsession with card games.
    • Yugi and Atem are both the Magician. Especially notable, since the Black Magician is their signature card.
    • Joey is The Fool.
    • Ishizu is the High Priestess.
    • Téa is the Empress.
    • Kaiba is The Emperor.
    • Shadi is The Hermit.
    • Malik is The Heirophant.
  • Tattooed Crook: Big Bad Marik Ishtar has a large tattoo covering his back and he is the leader of his own criminal organization. However, it was his reception of the tattoo that originally caused him to turn evil, rather than him getting the tattoo after turning evil. The tattoo was carved into his back in the Japanese version, though it’s similar, and the dub changes it to a tattoo.
  • Third Eye: The card "Goddess with the Third Eye." Also, Millennium Item holders connected to ancient Egypt (i.e., the Pharaoh and Yami Marik) sometimes get a glowing eye symbol on their foreheads when using their item, as do people possessed by Marik.
  • Took a Level in Badass: Joey/Jounouchi. As late as the Duelist Kingdom arc, he spams monster after monster without any regard of strategy, because he relies too much on the idea of beating things to death even though the attack stat is too low. It becomes apparent in the second episode of the show that he lost to Tea/Anzu, probably the least competitive player of all, because she knew a thing or two about magic and traps. It takes a lot of encouragement and guidance on the Pharaoh's part to help him, but by Battle City he grows into a very competent duelist and becomes a finalist, managing to go toe-to-toe against Marik.
  • Too Many Mouths: Slifer the Sky Dragon has two.
  • Tournament Arc: And how. The only arc two arcs that aren't tournaments are Waking the Dragons and Dawn of the Duel.
  • Traintop Battle: Or blimp-top, in Battle City. Played straight in Season 4 when Yami Yugi duels Weevil. In Season 5, there's a ferris wheel-top one.
  • Triang Relations: The DOMA arc gives us Jounochi and Valon for Mai, albeit not in a strict romantic sense: Both men view the other as an obstacle to Mai, but Valon seems to be in it for a relationship whereas Jounochi just wants her friendship, and for her to be free of her pain.
  • Truth in Television: Pegasus's Toon cards are said by Yugi to be kept out of circulation for being too powerful, but Pegasus is the creator of the game so he kept them for himself. The Seal of Orichalcos, a Game Breaker if there ever was one, exists in real life and is limited to a few copies that were used by members of Upper Deck's R&D department in a special tournament.
    • Until years later, when it got an official release to the public!
  • Ungrateful Bastard: Kaiba, after several rescues from Yugi and co. He does show some limited thanks for Yugi, and only Yugi, at times, such as freeing him from Pegasus and the Big Five.
  • Unstoppable Rage: Specifically, after Yugi's soul is taken by the Orichalchos, and Insector Haga/Weevil Underwood taunts the now rather unstable Yami by tearing up a card in front of him after claiming it contains Yugi's soul, just "as a joke," Yami... well, he goes totally and utterly apeshit, really. He defeats Haga/Weevil using a card that grants extra attacks by drawing and discarding monsters, and then he continues bashing at him by trashing more monsters long after Haga/Weevil's life points have hit zero. He would've kept going too, if Anzu/Tea hadn't stopped him. Here's the scene... Not pretty.
    • There's (possibly deliberately) an added Meaningful Echo — the last card in his hand (the one he would have tossed next if Anzu hadn't stopped him) is Dark Magician Girl. Not only is she the card spirit who asked him for help at the start of this arc, she quite frankly has seen enough of the Orichalcos effect to last a lifetime and could do without watching her master going nuts about it again.
  • Vendor Trash: When the rules got more defined, a lot of the worse cards didn't have Deus ex Machina powers anymore and were pruned, though some of them got updated versions that are useful.
  • Viewers Are Goldfish: Hey Yugi, remind me again, what does Pot of Greed do? Or how about flashing back to that play that happened one minute ago for those who missed it? Even if you have no idea how the card game actually works, you can follow every single duel in the later seasons because every single card will have at least ten seconds spent explaining its effect. Even if the card is used every single duel, its effect will be explained. This continued into Yu-Gi-Oh! GX, right up until Pot of Greed got put on the real-life banned list and the anime suddenly stopped using it.
  • Voice of the Legion: Marik's servants gain a double-voice when he is possessing them.
  • Virtue Is Weakness: This is the moral position of antagonists (Kaiba, Mai, Malik) in the series until Yugi or Jonouchi, the Embodiments Of Virtue, defeats them.
  • Waterfall Shower: The first season has this due to the fact that players are camping outdoors at night while they play the tournament.
  • We Can Rule Together: Noah makes this offer to Yugi in the Japanese version of episode 118, after Yugi manages a formidable counterattack and after Noah turns some of Yugi's True Compnions to stone:
    Noah: Seriously, though, that was splendid, Yugi! You possess both the skill and judgement necessary to catch your enemies off-guard the second they lose focus. When you think about it, you and I have no reason to be enemies. If you swear your loyalty to me, I'll save all your friends from Hell this very instant!
  • Warrior Therapist: Mai during her duel with Yugi in the Duelist Kingdom finals. She manages to talk Yugi out of his funk so that he can duel her with a clear and focused head. And it works! Definitely one of her most brilliant moments.
  • Welcome to Corneria: Both virtual realities suffer from this, despite how fleshed-out everything else in them is. Deconstructed in the latter, since Noah spent years trapped in his world and was driven mad by this.
  • Wham Line: From episode 52:
    Ishizu Ishtar: And the young man who stands behind the pharaoh... Above his head is the Blue Eyes White Dragon.
  • What Happened to the Mouse?: Gurimo from the first two episodes of the Waking the Dragons arc. Once he's finished being Mr. Exposition, everybody forgets about him, including his cohorts, even when all of the souls are being restored. Only the battle is referenced briefly during Raphael's last fight, prior to his Heel–Face Turn.
    • Also, the last time we saw Bones and his friends, they were put into the Shadow Realm by Yami Bakura. Nobody ever rescues them. Maybe Zorc's ultimate defeat released them.
    • That's the dub. They're dead in the original Japanese version (and in the manga).
  • What the Hell, Hero?: Rebecca does this to Yami when his reckless use of the Seal of Orichalchos results in Yugi losing his soul. Heck, even WEEVIL does this effectively, pointing out that although he might be an asshole, at least he didn't knowingly endanger his friend simply to win.
  • Wine Is Classy: In the original, there's a scene where Pegasus is drinking a glass of wine. For the dub, this got changed to "the world's finest fruit juices".note 
  • With Friends Like These...: Anzu and Honda are complete assholes to Jonouchi in the anime.
  • Wok Fu: Yugi faces off against Vivian Wong inside a Chinese restaurant. His friends get distracted from their usual Power of Friendship cheerleading routine by all the food.
  • The Worf Barrage: Kaiba's Crush Card. Number of times he tries to use it: Seven. Number of times it actually works: Three, and of those three times, Yugi found ways to work around it and lost for entirely unrelated reasons and Ishizu made its effect work to her advantage and turned it back on Kaiba. So, really, of the seven times he uses it the Crush Card only works the way he plans it to once. Though, the one time he couldn't get it off normally, he was able to combine it with the Fang of Critias and win that way.
  • The Worf Effect:
    • The anime adds several duels not in the manga for Joey, most of which he loses.
    • Mai Valentine/Kujaku. Top-notch duelist who gets seeded off against the most dangerous opponents, eventually becoming deconstructed in Season 4. Despite being a very skilled duelist, she keeps going up against super-powerful opponents to show the viewers how hard it'll be for the other heroes to win. On top of what Marik does to her, she starts to have a breakdown over it (to the point of destroying a first-place trophy she just won), and Dartz is able to brainwash her over to the villains' side because of it.
  • World of Ham: Especially when two hams duel against each other. The Kaiba/Yami matches go Up to Eleven compared to others because of their rivalry.
  • Xanatos Gambit:
    • Used by Yami Marik during his duel with Yami Yugi. Marik manipulates the game so that when a player takes damage to their life points, normal Yugi and normal Marik suffer the damage as well. If Yami Yugi loses the duel, then Yugi is consumed and Marik walks free. However, if Yugi wins then Yami Marik walks free anyway, seeing as his good half is destroyed instead. It's subverted at the last minute.
    • Used in the final duel between Yugi and Atem. Yugi correctly predicts that his opponent has a Mirror Force trap, used to destroy any attacking monsters. He attacks anyway. Had he been wrong, his attack would have gone through anyway and destroyed Atem's monsters. Had he been right (which he was), then Yugi had a plan in place to immediately counteract it.
  • You Would Make a Great Model: Happens to Anzu/Tea, who is promised a chance to be a dancer like she's always wanted.
  • Zeno's Race: Inverted with the pharaoh's backstory, seeing as how more information is revealed from the early manga, to Duelist Kingdom, to Battle City, to the Millennium World.
  • Zerg Rush: At one point, Yugi uses Monster Multiply, which causes Kuriboh to multiply each turn, in conjunction with Kuriboh's special ability that allows it to nullify the damage done by one enemy monster. Due to there being no limit on how many monsters can be summoned with one magic card in the anime's version of the game, this allows him to create a virtually impenetrable barrier of the little guys.
  • Zettai Ryouiki: Rebecca Hawkins manages to pull off a grade-A in her initial appearance. Also, she's twelve years old.
