There were actually two Franchise/YuGiOh anime series: [[Anime/YuGiOhFirstAnimeSeries The first anime]], which covers the first seven volumes of the [[Manga/YuGiOh manga]], made by ToeiAnimation; and this one, ''Yu-Gi-Oh: Duel Monsters'', which was produced by NAS, animated by Creator/StudioGallop, 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 was also given the subtitle of "Duelist" in the English localization. It was sponsored by Creator/{{Konami}} as a successful attempt to remain dominant of the license to the card game, after it stripped it away from Creator/{{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 ''[[Anime/YuGiOhTheMoviePyramidOfLight The Pyramid of Light]]''. This version of Yugi and his alter ego return in ''Anime/YuGiOhBondsBeyondTime'' that [[BatFamilyCrossover teams him up with Jaden and Yusei.]] ''Anime/YuGiOhTheDarkSideOfDimensions'' was written to take place six months after the manga continuity in the Japanese version, but takes place a year after the anime in the West and is the first ''Yu-Gi-Oh!'' anime adaptation with direct involvement from Kazuki Takahashi.

This show in particular is also responsible for the creation of ''TheAbridgedSeries'' genre of internet videos, with ''WebVideo/YuGiOhTheAbridgedSeries''.

The dub is [[http://www.hulu.com/yu-gi-oh available on]] {{Creator/Hulu}}, [[http://www.yugioh.com/episodes the official Yu-Gi-Oh website]], and is now starting [[http://www.netflix.com/WiMovie/70177034?trkid=13462100 to appear on]] Creator/{{Netflix}}.

!!"It's time to trope!"


[[folder:A - M]]
* AbandonedWarehouse: Bandit Keith duels Yugi in an abandoned warehouse that has its own Duel Monsters arena.
* AbortedArc: 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. 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 mostly 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. Seto rebelling against the Pharaoh on his own was intended to be a larger plot point that didn't end up happening, so he ended up brainwashed.
* AbsurdlyHighStakesGame: Shadow Games plus Duel Monsters means 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 the loser is left with an empty shell of a body.
* AbusiveParents: Gozaburo Kaiba, and Marik and Ishizu's father.
* AccentAdaptation: 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.
* ActingUnnatural: 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.
* AdaptationDyeJob: 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.
* AdaptationalWimp: Yugi's friends are hit with this.
** Jonouchi/Joey in the anime. When Bandit Keith tries to steal his card during the Duelist Kingdom Arc, Jonouchi beats him up, claiming that while Keith may be good at card games, he's the best at fighting. In the anime, Jonouchi gets beaten up rather ungracefully instead. He also had more anime-exclusive losses.
** Anzu, whose cheerleader role is played up, and her temper and active personality reduced.
** Honda in the manga was a badass with a sense of honor. In the anime, he's more of a comic relief character that tries to get with Serenity, though he does duel and fight now and then.
** Otogi goes from a serious, somewhat sympathetic character in the manga to a jerkish villain in the anime before mellowing out. He eventually becomes stuck in a comedic love triangle, competing with Honda for Shizuka's affections.
** In his first appearances, Dark Yugi used MindRape on anybody who cheated or appeared to screw with his friends, which continued in the manga until the end of Duelist Kingdom where he decided to stop doing his own Shadow Games, as Pegasus warned him that ''every'' Millennium Item was infleunced by evil. In the ''Duel Monsters'' anime, he just played Duel Monsters with a Mind Crush penalty that stopped being used for no explanation.
* AdaptationExpansion:
** 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.
** Serenity's character is slightly expanded, as she gets to duel in the Virtual World using a female monster-deck. Her adoration of Joey and friendship with Mai is given more focus as a result.
** The Dungeon Dice Monsters arc was turned into ''three'' unrelated stories. In the manga, a big chunk of Ryuji/Duke's motivation came from his dad being an old rival of Yugi's grandpa, which Rebecca took over in the anime. Meanwhile, the whole "Yugi almost dies in a fire" plotline that concluded the arc got shoved into the Yugi vs. Marik/Bandit Keith duel that kicked off the anime version of Battle City. And last, but not least, the anime did its own version of DDM, which featured a completely different take on Ryuji but was otherwise faithful to the manga story.
** Bakura's Battle City duel with "Ghost" Kotsuzuka, which lasts ''one page'' in the manga, is given its own episode in the anime.
** The Memory World arc expanded Seto and Kisara's role, having them meet as children in backstory. Kisara was also made more assertive, Bakura and Mahad's duel was elaborated on, and Tea and Tristan were able to contribute to the final battle.
* AdaptationExplanationExtrication:
** 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 ExactlyWhatItSaysOnTheTin. 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, which Mokuba had). The dub actually makes a little more sense, with him being after Mokuba's soulless body instead.
** 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.
* AdaptationInducedPlotHole: 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.
* AerithAndBob: 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.
%% * AloofBigBrother: Seto Kaiba to his brother Mokuba.
%% ** Zigfried von Schroeder may as well count, too.
* AlternativeForeignThemeSong: As with all the anime that 4Kids dubs, the English opening is different from the Japanese opening. You can listen to it [[http://www.youtube.com/watch?v=HeRC0Cu-QOQ here]].
* AmuletOfConcentratedAwesome: 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.
* AncientEgypt: A large chunk of the characters and [[MacGuffin artifacts]] come from this time period. It is also the backdrop of the final Shadow Game.
* AngelFaceDemonFace: The differences between Yugi, Bakura, and Marik's normal appearances and when their [[SuperpoweredEvilSide Yami]] sides take over. [[SubvertedTrope Though,]] Yami Yugi [[AntiHero isn't]] the most demonic per se, and normal Marik [[BigBad isn't the most angelic]].
* AnimationBump: 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.
* AnimeHair: 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.
* ArcWords: "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.
* ArtifactOfDoom: Millennium Items tend to give their owners awesome PsychicPowers of some sort. However, more often than not, they will also harbor or lead to the development of their owners' {{Superpowered Evil Side}}s, or at least contribute to their [[FaceHeelTurn Face-Heel Turning]].
* ArtifactTitle: "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.
* ArtisticLicenseHistory: Beyond the parts that [[SadlyMythtaken never would have been accurate to begin with]], other AnachronismStew 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.
* ArtShift: Once Yami defeats Kaiba and performs a mind crush on him, his face becomes less angular and his eyes gain pupils.
* AscendedExtra: 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.
* AscendedMeme: The nicodouga phenomena relating to the "Enemy Controller" scenes from the Virtual Arc is referenced in a minigame on the Duel Terminal arcade game.
%% * AssholeVictim: Bandit Keith, but especially Marik's father. [[spoiler:Weevil in the "Waking the Dragons" arc.]]
* AstonishinglyAppropriateAppearance: 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.
* AttemptedRape: 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. 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.
* AwesomeButImpractical:
** Pretty much every character's deck only works because of TheMagicPokerEquation and the fact that the writers can let them get whatever cards they need.
%% * AVillainNamedZrg: Zorc.
* AxCrazy: Yami Marik and Yami Bakura (the latter is more WickedCultured in the dub, but still has shades of this). Even our hero Yami Yugi can become AxCrazy [[RoaringRampageOfRevenge if you push the right buttons.]]
* BadassAdorable: Yugi, mostly because the anime puts more emphasis on his youthful looks, compared to Atem.
* BadassNormal:
** 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.
* BaitAndSwitchCredits: The final opening for the Millennium World arc is more faithful to the manga than the anime, lacking the diadhanks that the priests had in the anime but didn't have in the manga.
* BeamOfEnlightenment: 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.
* BeastInTheMaze: The three-part duel with the Paradox Brothers is all about this.
* BeautyEqualsGoodness: The heroes' ace monsters are [[BadassAdorable drop]] [[MsFanservice dead]] [[HeroicBuild 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 Side}}s take over, they look significantly rougher and are prone to making terrifying faces.
* BerserkButton: 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 [[PapaWolf attempt to kidnap/harm Mokuba.]]
* BetweenMyLegs: This shot is how Rebecca is introduced in her first appearance.
* BewareTheNiceOnes:
** Ryou Bakura is a very sweet, shy, quiet, polite guy with a SuperpoweredEvilSide 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.
* BigBad: Kaiba, Pegasus, The Big Five, Noah/Gozaburo, Marik, Dartz, and Zorc/Bakura. Subject to the SortingAlgorithmOfEvil.
* BigDamnHeroes: 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.
* BigShutUp: 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.
* BilingualBonus:
** 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 [[DidDoTheResearch 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.
* {{Bishonen}}: Marik Ishtar, Ryou Bakura, and Ryuji Otogi/Duke Devlin. The latter two even have their own in-universe fan clubs.
* BitchInSheepsClothing:
** 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 [[ManipulativeBastard 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.
* BlackBox: The IC chips inside the cards are described as this in the Pyramid of Light novelization.
* BlackCloak: Marik Ishtar and the other Rare Hunters are garbed like this when they are first introduced.
%%** Also in the Waking the Dragons arc.
* BlackMagicianGirl: TropeNamer due to the "Dark Magician Girl" card, which is actually named "Black Magician Girl" in the original anime.
* BlindIdiotTranslation: The card known in Japanese as "Shisha Sosei", literally "Raise Dead", is called "Reborn the Monster" early in the English dub. It's later changed to "Monster Reborn", which makes more sense.
* BodySurf: Marik causes much grief to the protagonists by doing this during the Battle City arc.
* BookEnds: Yugi's winning card in the last duel of the series is Golden Sarcophagus; it's [[LampshadeHanging pointed out]] that the card looks just like the box the Millennium Puzzle was in, [[spoiler:[[InvokedTrope and that the box that brought Yugi and the pharaoh together would be the very thing to bring them apart.]]]]
* {{Bowdlerise}}:
** Of the manga: skipping approximately the first seven volumes of Dark Yugi challenging bullies/criminals to Shadow Games and inflicting Penalty Games, disregarding Kaiba's death-themed amusement park, and changing Dark Yugi's Penalty Games into Mind Crushes, among other things. Duelist Kingdom, Dungeon Dice Monsters, and Millennium World get most of this treatment, whereas Battle City gets less of it.
** 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 had most of them be Shadow Games anyway thanks to Marik's magic.
* BreakoutCharacter: The Dark Magician Girl, being the MsFanservice 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.
%% * BreakTheHaughty: Kaiba gets this a lot.
* BreatherEpisode:
** 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.
%% * BrokenBird: Mai Valentine/Kujaku.
* BrokenBridge: 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.
%% * BroodingBoyGentleGirl: Priest Seto and Kisara in Ancient Egypt, Yami Yugi and Tea in the main timeline.
* ButNowIMustGo: [[spoiler:Atem]] has to pass on to the afterlife after he saves the world from the Shadow Games once and for all.
* CallingYourAttacks: "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's happening.
* CalvinBall: 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.
* CCGImportanceDissonance: Countless examples, the most famous of which are the Dark Magician, Blue-Eyes White Dragon and Red-Eyes Black Dragon. Later releases have done more to keep them viable, but they're still fairly specialized decks.
* ChainedByFashion: Exodia has chains on his wrists and ankles.
** Yugi later uses a chain necklace for his Millennium Puzzle.
* CharacterCheck: In the Doma arc, Yami Yugi regresses to a more vengeful persona without Yugi around, much like the earlier manga, and tortures Insector Haga/Weevil in a fit of rage until Anzu convinces him to stop.
%% * CharacterDevelopment: Mostly for the two Yugis, but everyone gets a decent amount at the least.
* CharlesAtlasSuperpower: 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.
* ChastityCouple: Mai and Jounouchi/Joey. Also Yugi and Anzu/Tea, though the latter has a crush on the former's [[SuperpoweredEvilSide superpowered evil side]].
* ChekhovsGun: 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 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.
* CherryTapping:
** Yugi manages to stall off Kaiba's Blue-Eyes Ultimate Dragon with Kuriboh, one of the weakest monsters in the game.
%% * TheChewToy: Joey, to Kaiba.
%%* ChronicHeroSyndrome: Yugi
%%* CircleOfFriendship
* ClipShow: Episode 74, "The Rescue," is almost entirely a clip show of everything up to that point.
%%* ClosedCircle:
%%** In the Virtual World arc.
%%** Also in the Dawn of the Duel arc.
%% * CloudCuckoolander: Jounouchi/Joey.
%% * CockFight: Tristan and Duke, over Serenity.
* CollectibleCardGame: Duel Monsters, which the entire series is centered around.
* ConspicuousConsumption: Siegfried has a fancy castle, an army of maids, private jets, and swimming pools filled with fresh milk... to hide the fact that his life of luxury is in jeopardy since [=SchroederCorp=] is going broke.
* CookingDuel: Figuratively speaking. The series often stakes the lives of its characters, or even the fate of the world, on a game of Duel Monsters.
%% * CoolBigSis: Mai Kujaku plays this role to Serenity.
%% * CosmicChessGame: Season 5 is like a Cosmic Role-Playing Game
%% * TheCorruption: Multiple instances with various characters. Some of the Millennium Items have an element of evil in them. The entire Doma arc works on this, with the Orichalcos stones being the catalyst.
* TheCracker: In an early episode, Seto Kaiba goes through a Batman-esque security system to reach a sentient computer, which he uses to hack into Pegasus's computer system to [[MundaneUtility mess with a duel]].
%% * CrazyConsumption: Yami Bakura and his steak. Censored in the dub.
* CurbStompBattle: 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.
%% ** The first Kaiba vs. Joey duel.
%% ** Zigfried VS Weevil and Rex. At the same time. ''In one move.''
** 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. He summons Obelisk on Round Two, sacrifices his other remaining monsters to activate Obelisk's TotalPartyKill special ability to defeat both opposing players.
%% ** The Winged Dragon of Ra versus basically anything, except for Mai's CriticalFailure attempt at using it.
%% ** The first Kaiba/Pegasus battle becomes one as soon as Toon World is played. Later Kaiba smartened up.
%% ** Nameless PlayerMooks versus numerous {{Designated Villain}}s like Rex and Weevil.
%% ** Valon defeats Rebecca and Duke on his second turn.
%% * CutAndPasteTranslation: Most infamously the [[NeverSayDie Shadow Realm]] concept.
%%* CutesyDwarf: Yugi.
* TheDarkSide: Many characters in Yu-Gi-Oh! fall into some Dark Side's trap, usually by trying to use an ArtifactOfDoom. Yami Yugi is not immune to this effect.
* DarkerAndEdgier:
** In the manga, Yugi's grandpa wasn't really ''kidnapped'' by Pegasus; his soul was instead sealed inside a video tape, and Yugi could talk with him through a camcorder whenever he liked. The anime makes it a straight case of YourSoulIsMine, and anime!Yugi is appropriately angstier about the whole affair.
** While the manga makes it clear that receiving the Millennium Eye was ''[[EyeScream not]]'' pleasant for Pegasus, the actual insertion was done off-panel. The anime, on the other hand, lets the audience see every second of Shadi painfully jamming it in the poor guy's eye socket.
* DeadManWriting: Subverted with Pegasus in the Doma filler saga. [[spoiler: He isn't dead, merely comatose due to his soul being removed]].
* DeadpanSnarker:
** 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.
%% * DeathByChildbirth: Marik's mother.
* DebtDetester: 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 HiddenHeartOfGold.
* DefeatMeansFriendship: Ryuji Otogi/Duke Devlin in the ''Dungeon Dice Monsters'' arc. To an extent, Mokuba Kaiba and Marik Ishtar later on.
* DefrostingIceQueen:
** Mai Kujaku/Valentine for the first few arcs, and then heads back to Arctic levels during most of Season 4 due to her FaceHeelTurn.
** Kaiba is a male example, at least in the Japanese version. He becomes more amiable and less openly insulting towards the others over time.
* DemotedToExtra:
** 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. [[spoiler:In fact, in the manga, Bobasa ''is'' an alternate identity of Shadi/Hassan.]]
* DependingOnTheArtist: 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 [[OvertookTheManga 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 OffModel.
%% * DesignatedVictim[=/=]DistressBall: Hiroto Honda/Tristan Taylor falls here sometimes. Many of Yugi's rivals fall into this trope, too.
* DeterminedExpression: 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.
* DetonationMoon: 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 [[http://yugioh.wikia.com/wiki/Attack_the_Moon! its own card.]]
* DeusExMachina: 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".
* DeusExitMachina: 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 QuirkyMinibossSquad 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.
* DidDoTheResearch: Though occasionally the exact details are fuddled, the mythological concepts explored throughout the franchise show that someone obviously did their homework.
* DoNotAdjustYourSet: Kaiba appears on every Tv screen in the city to announce the Battle City Tournament.
* DubInducedPlotHole: In Season 2 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 Villain}}s.
** 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, 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 all mention of his entrance in the District Tournament disappears. This ends up causing a bit of confusion when Season 3 rolls around and [[spoiler: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]]. In the dub [[spoiler:he's just straight-up dreaming and is told this by Yugi in the dream, turning it into an EpiphanicPrison of sorts as he fights his way out of the Shadow Realm.]]
** 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 just says that Exodia is very rare.
*** In English dub, a moan is added when Pegasus's body is shown, explaining how he is alive for season 4 and 5.
* DubNameChange: The dub was done by Creator/FourKidsEntertainment, 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]] DudeNotFunny:
** 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.
* DudeWheresMyRespect:
** 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.
* DuelsDecideEverything: 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.
%% * DysfunctionJunction: Several characters experienced a tragic and/or depressing event in their life, especially the villains.
* EarlyInstallmentWeirdness: Duelist Kingdom uses completely different rules 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.
** 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.
%% * EasilyForgiven: The Kaiba brothers, Pegasus, Malik.
%%* EmbarrassingRescue
* EnvironmentalSymbolism: Whenever Shadi [[JourneyToTheCenterOfTheMind goes into someone's Soul Room]] with his Millennium Key, the environment reflects their personality and mental state.
%% * EvilIsNotAToy: Nor is it a card game, ''Pegasus''.
* EvilSoundsDeep: 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 [[LarynxDissonance high-pitched squeaky effeminate voice]]. Played straight in the dub.
** Also used with Marik when his SuperpoweredEvilSide isn't in control. When he's pretending to be a protagonist, and after his HeelFaceTurn, 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 HeelFaceTurn, it gets lower and more mature.
%% * EvilVersusEvil: The duel between Yami Marik and Yami Bakura is this.
* ExactlyWhatItSaysOnTheTin: A lot of the cards, like "Red-Eyes Black Dragon," "Man-Eating Treasure Chest," and "Dark Magician," just to name a few.
** Ladies and gentlemen, feast your eyes upon the [[http://yugioh.wikia.com/wiki/Giant_Turtle_Who_Feeds_on_Flames Giant Turtle Who Feeds On Flames]]!
* {{Expy}}: At one point, Yugi and Tea go up against a guy (nick)named Johnny Steps at a VideoGame/DanceDanceRevolution clone. Doubly hilarious seeing as DDR is also put out by Konami.
* ExtraEyes: Pegasus' Thousand-Eyes Restrict somehow has, as the name implies, one-thousand eyes covering its body.
* FaceFramedInShadow: Every major villain has this going on for them, especially friends who have been made BrainwashedAndCrazy.
** 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.
* FadeAroundTheEyes: 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 PurpleEyes.
%% * FairytaleWeddingDress: In a fantasy sequence in the first anime.
* {{Fiction 500}}: Seto Kaiba is the president of a multi-billion-dollar gaming company, which he [[TheCoup took]] from his stepfather [[ChildProdigy while still a kid]].
%% * FetalPositionRebirth: Yami Yugi at the end of the Orichalcos Arc.
%% * FieldPowerEffect: Various boosting and nerfing cards, as well as terrain.
%% * FightingSeries: Using a card game.
%% * FillerArc: Virtual World, DOMA, and Kaibacorp Grand Prix.
%% ** Kaiba hilariously lampshades this directly after the Virtual World Arc, directly after they've all narrowly escaped with their lives.
%% --> Kaiba: Alright, that little detour was a complete waste of my time and effort. So let's move on and pretend that nonsense never happened. It's time for us to continue the Battle City Finals! Set us back on course, to Kaiba Corp Island.
%% * FillerVillain: Noah and Gozaburo, Dartz, and Zigfried von Schroeder, respectively.
* FirstEpisodeSpoiler: 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.
* FiveBadBand: The Big Five. In the DOMA/Orichalcos filler arc, there's Dartz and his men (if you include [[spoiler:Mai]]). You could also make a case for Pegasus and his Player Killers if you wanted. For the DOMA Arc:
** BigBad - Dartz
** TheDragon - Rafael
** TheBrute - Valon
** TheDarkChick - [[spoiler:Mai]]
** TheEvilGenius - Alister
** [[SixthRanger Sixth Ranger]] - Gerimo
** [[TagalongKid Tagalong Kids]] - [[spoiler:Weevil and Rex]]
* FiveManBand
** TheHero - Yami Yugi/Yugi
** TheLancer - Jounouchi (Joey)
** TheBigGuy - Honda (Tristan)
** TheSmartGuy - Yugi/Kaiba when he's not being a {{Jerkass}}/ Rebecca in Season 4 and 5
** TheChick - Anzu (Tea)
** SixthRanger - Bakura in the first season, Ryuji Otogi (Duke) in later seasons.
* {{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.
* FreudianExcuse:
** The whole reason [[spoiler:Thief King Bakura]] tried to take over the world in the first place is because he saw [[spoiler:the Kul Elna massacre]] first-hand and was its only survivor, thus making a deal with [[spoiler:Zorc]] for power.
** Also Seto, arguably, given his orphaned childhood and [[AbusiveParents history with Gozaburo]].
** Marik's SuperpoweredEvilSide developed as a result of his unwilling upbringing as a tomb keeper (with some help from the [[ArtifactOfDoom Millennium Rod]]), which involved isolation, abuse, and an excruciatingly painful initiation ritual.
* FriendlessBackground: Yugi had one of these before finishing the puzzle.
* FriendshipMoment: Given the [[ThePowerOfFriendship main theme]] [[TrueCompanions 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.
* FrothyMugsOfWater:
** In the dub, Pegasus is clearly drinking wine, but he refers to it as grape juice or fruit punch. Given Pegasus's [[ManChild character]], though, this holds up better than most.
** Averted in TheMovie, wherein Pegasus wakes up from what he thinks is an AcidRefluxNightmare 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.
* FunSize: Yugi Mutoh is a shorter version of Yami with fewer blond streaks in his hair.
* GeoEffects: Field Power Bonus. Emphasized very much earlier in the card game, but dies out to only Field Spell Cards by the Duelist Kingdom finals.
* GenkiGirl: Mana, whose introduction consists of her jumping out of a vase to glomp the pharaoh.
* GetAHoldOfYourselfMan: Yami gets one of these from Joey in the form of a punch to the face.
* GirlsLoveStuffedAnimals: 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 [[TastesLikeDiabetes "cutesy little girl"]] angle, and Teddy is nowhere to be seen.
* GottaCatchEmAll: 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 CollectableCardGame, all the characters in ''Franchise/YuGiOh'' 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).
* GracefulLoser: 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.
* GradeSchoolCEO: 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.
%% * GrandTheftMe: Gets attempted MANY times. Usually tends to fail, but succeeds on rare occasions.
* GratuitousEnglish:
** Pegasus in the Japanese anime.
--->'''Pegasus:''' ''UNBELIEVABLE!'' Kore wa NIGHTMARE! Bad dream!
** Most of the cards have names in GratuitousEnglish 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).
* HackedByAPirate: Pegasus does this by showing his favorite cartoon rabbit character when he counter-hacks Kaiba trying to hack into his system.
%% * HackerCave: Owned by Seto Kaiba.
* HamToHamCombat: 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.
%% * HannibalLecture: During every single duel against a major rival.
%% * HardWorkHardlyWorks: Yugi plays it straight, Joey/Jounouchi actually earns his wings through hard work.
* HealthcareMotivation: 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.
%% * HeelFaceTurn: Marik, and Pegasus in the anime.
* HeroicWillpower: Joey/Jonouchi's main strength is this, as he displays in various ways in his confrontations with Marik.
%%* HeroicSafeMode: Yami to Yugi.
* HeterosexualLifePartners: 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, [[spoiler: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.
%% * HollywoodHacking: Complete with virtual doors that can be blown up with virtual dynamite...
* {{Homage}}: The card game was originally intended as an homage to ''TabletopGame/MagicTheGathering'', of which Takahashi is a fan.
* HostageForMcGuffin: So much so (especially with Kaiba's little brother Mokuba) that [[http://www.dailymotion.com/littlekuriboh/ LittleKuriboh]]'s GagDub of the show has an entire running gag built around it.
* HotForTeacher: 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.
* HotBlooded:
** 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."
* HybridOverkillAvoidance: 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.
%% * IAmYourOpponent: Used a few times by Yugi.
* IdiotBall: 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]]This may be more justified in the manga, where the duel is shown through a montage instead of mapping out every move.[[/note]]
** Yugi's largest IdiotBall 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 RuleOfDrama, since apparently if it'll make for a dramatic twist then duelists can activate cards without announcing such (e.g., Ishizu 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.
* IfIHadANickel:
-->'''Seto''': If I had a dime for every time you said the word "destiny," [[DeadpanSnarker I'd be even richer]].
* IHaveYourWife: Used by various villains throughout the series. The target is usually Mokuba, who is kidnapped a grand total of 15 times.
* IJustWantToHaveFriends: When Yugi first completes the puzzle, he makes a wish on it to have some true friends.
* IKnowYoureInThereSomewhereFight: Yugi has one of these with Joey/Jounouchi when Marik takes control of him. Jounouchi has one with Mai in Season 4, the latter [[spoiler:having to lose his soul just to snap Mai back to normal.]]
%% * IllGirl: Shizuka/Serenity, though she gets better.
* InTheEndYouAreOnYourOwn: 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 [[UnstoppableRage Wrath]] and [[GreenEyedMonster Envy]] talking.
%%* InactionSequence: Very, very often.
* InadequateInheritor: In the Virtual World arc, Gozaburo says he considers Seto this.
* IndyEscape: {{Subverted}} during Duelist Kingdom. The boulder in question was just a balloon with a speaker in it.
* IneffectualLoner: Seto Kaiba. As far as he's concerned, the only option is victory. And the only allies... are enemies.
* InformedAbility:
** 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|Guys}} {{Butt Monkey}}s 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 [[ForTheLulz enjoys it]]. Other than [[BornLucky Joey]], Weevil's only ever lost to [[SuperWeight exceedingly great duelists]]. The main reason he becomes a joke character is because he's a SmugSnake who CantCatchUp as far as powerful cards go.
* InsaneTrollLogic: 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.
* InstantAwesomeJustAddDragons: 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.
* InsultToRocks: "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."
* IntergenerationalFriendship: Big time, between Yugi and [[ReallySevenHundredYearsOld the Pharaoh/Yami Yugi]].
%% * InterplayOfSexAndViolence: Yami Marik seems prone to invoking this in his duels.
* InvincibleIncompetent: 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.
* InvincibleVillain: FillerVillain 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 BigBad 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]]He is possessed by the Orichalcos for most of the arc, so read into that how you will[[/note]].
* IronicEcho: 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 [[spoiler:Yami]]. Yugi hesitates on finishing the duel, but carries it out, as this time, the reason is [[spoiler:to send Yami to the afterlife]].
* IWillShowYouX: When Tristan has an open crush on Joey's sister Serenity, which Joey is [[BigBrotherInstinct 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!"
%%* ItMeantSomethingToMe
* {{Jerkass}}:
** Kaiba is an IneffectualLoner 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.
%% * JerkWithAHeartOfGold: Jounouchi/Joey and Honda/Tristan.
* JokerJury: 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.
* KarmaHoudini: 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 expelled him, but the original version never says anything beyond that, implying he got off completely scot-free for what he did.
* KickTheDog: 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 [[BreakTheCutie mess with the already broken duelist]]). This [[KickTheSonOfABitch does not]] [[NoHoldsBarredBeatDown end well]] [[MomentOfAwesome for Weevil.]]
* KingOfGames: TropeNamer; 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.
* KingOfThieves: Thief King [[spoiler:Bakura]], [[spoiler: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 [[TheHeartless Diabound]], and because he seeks (and even got all) the [[ArtifactOfDoom millennium items]], until he was [[SealedEvilInACan imprisoned into one]] of them, that is.
* KnightTemplarParent: 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.
* KnowWhenToFoldEm: 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.
** ...Though the first time was a lie, essentially [[AvertedTrope averting the trope.]]
%% * LargeHam: Pegasus, in the original manga, anime, and dub versions.
%% ** Dark Yugi, especially [[Creator/DanGreen in the dub.]]
%% ** Dark Marik.
* LethalJokeItem: 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 VideoGame/{{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.
* LetsFightLikeGentlemen: They settle every conceivable difference via a ''collectible card game'', for cryin' out loud!
* LettingTheAirOutOfTheBand: Happens during Yugi's final duel with Marik. [[spoiler: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.
* LighterAndSofter: Compared to the manga.
** Within the anime, the KC Grand Prix, a [[BreatherEpisode breather arc]] with a campy villain whose crime is [[ArsonMurderAndJaywalking not mind-rape, not soul-stealing, but hacking into Kaiba's computer system.]]
%% * TheLoad: Mokuba. Serenity. Tea and Tristan, who are pretty much just around to provide moral support ([[LampshadeHanging Lampshaded multiple times]]).
* LovelyAssistant: StageMagician 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.
%% * LoveMakesYouEvil: Pegasus' motive. Also, Akhenaden to some extent.
%%* LoveMartyr: Odion.
%% * LukeIAmYourFather: Akhenaden reveals this to Priest Seto in the Memory World arc.
* LullDestruction: Compare the Dub to the Japanese version. Some scenes have added dialogue, especially if in the original the characters are silent.
* MagicalEye: Pegasus' Millennium Eye, possessing the power to read minds and probably do other sinister things. According to WordOfGod, it also [[{{Brainwashed}} brainwashed]] Pegasus into creating Duel Monsters, making it a literal evil eye.
* TheMagicPokerEquation: 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 PlotArmor, 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.
* MarkOfTheBeast:
** If a character has a glowing eye symbol on their forehead, has MindControlEyes, and talks in a [[VoiceOfTheLegion creepy superimposed voice]], it's most likely that Marik is [[BodySnatcher remotely possessing them]] using his [[ArtifactofDoom Millennium Rod]].
** If you find someone with a green circle on their forehead, they probably want your soul so they can feed it to their ancient beast.
* MeaningfulName: Happens for a couple of characters, particularly the (ancient) Egyptian ones:
** If Marik's name were [[SpellMyNameWithAnS transliterated]] differently when moving into the English dub, it would be the Arabic name [[http://www.behindthename.com/name/malik Malik]] (or "ملك" in Arabic), which is based on the words for "king" or "possessor" in the Arabic language. Incidentally, Marik [[BodySnatcher possesses]] several people and [[TakeOverTheWorld wants to be the pharaoh/king of Egypt/the world]] as a BigBad.
** Also Odion's name in the Japanese version is [[http://www.behindthename.com/name/rashid Rashid]] (or "راشد"), meaning "rightly guided" in Arabic. Odion/Rashid is Marik/Malik's older adopted brother and serves as one of his two [[MoralityPet Morality Pets]] in the series.
** Shadi's name is only a phoneme different from the ancient Egyptian word ''[[http://www.ancientegyptonline.co.uk/shabti.html 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 [[PoweredByAForsakenChild actual]] [[HumanSacrifice servants]] for this sole purpose. Shadi guards the Millennium Items' original resting place and [[spoiler:[[DeadAllAlong 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 [[http://www.behindthename.com/name/shadi-1 Arabic]] in origin, [[ShownTheirWork 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 [[http://www.touregypt.net/magazine/mag08012001/magf5.htm Isis]]. Isis is the queen of [[ReligionIsMagic magic]], [[DueToTheDead dedicated wife]] to her murdered and undead husband Osiris, and honored for being a [[MamaBear good mother]] to her son [[{{Protectorate}} Horus]]. Ishizu is a MysteriousWaif of a character who can [[SpiderSense see the future]] using her [[AppliedPhlebotinum Millennium Necklace]]. One of her major goals is to stop her [[FaceHeelTurn Face-Heel Turned]] younger brother Marik from being [[BigBad villainous]]. She is also another one of Marik's [[MoralityPet 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 ([[IncrediblyLamePun "Game", "Set", Match]]) for one meaning, but for the other, Set was the Egyptian desert god, a completely appropriate name for a [[spoiler: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, [[spoiler:Atem]], is a variation on [[spoiler: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.]]
* MindControlEyes: People under Marik's control have their eyes drawn without pupils.
* MindScrew: 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.
%%** Shadi, good lord.
* {{Mondegreen}}: No, [[http://www.youtube.com/watch?v=ErCUh8Z-uO4 the dub theme]] is not misspelling Yami as [[EarWorm Yamu]], it is actually ''Your Move''.
* MoralityPet: Mokuba Kaiba is one for his brother Seto. Odion and Ishizu Ishtar are the same for their master/brother Marik.
%% * MoreThanMindControl: Dartz in Season 4.
%%* [[TheMovie The]] SoBadItsGood [[TheMovie Movie]]
* MsFanservice: Mai Valentine and Dark Magician Girl.
* MulticoloredHair: 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.
%% * MundaneMadeAwesome:
%% ** "Card games are serious business."
%% ** Dramatically animated belt clipping-on sequence?
* MusicalPastiche: The track [[https://soundcloud.com/theshugotv/yu-gi-oh-bgm-the-priests "The Priests"]] in the Japanese OST is a pastiche of [[http://soundcloud.com/theshugotv/cyberteam-in-akihabara-bgm the transformation theme]] from ''Anime/CyberTeamInAkihabara'', it's not too surprising since both show's share the same composer, Shinkichi Mitsumune
* MusicalSpoiler: As if the LikeYouWouldReallyDoIt nature of the scene is not enough, the lack of the "Life Points hitting 0" sound effect when [[spoiler: Dartz brings Yami Yugi's LP down to 0]] makes it very obvious that the duel is not over.
* MyLittlePanzer: Duel Monsters is such a safe game for little kids, isn't it?
** {{Subverted}}: By itself, the game is perfectly safe; it's the duelists like the Ghouls that add in their own, more dangerous, rules or invoke the dark magic of the Millennium Items that make it so [[DepartmentOfRedundancyDepartment dangerous]].

[[folder:N - Z]]
%%* NecessaryFail
* {{Necromantic}}: Pegasus got his StartOfDarkness after his beloved wife Cyndia/Cecilia passed away and he vowed to bring her back.
* NeverSayDie: 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 GettingCrapPastTheRadar, since that's what a CorruptCorporateExecutive (or a member of TheMafia) would do to a business rival.
* NewPowersAsThePlotDemands: 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.
** The Winged Dragon Of Ra is especially guilty of this; it seems like every time [[BigBad Yami Marik]] plays it, Ra just happens to have a previously-unused power that just happens to [[NotSoFastBucko perfectly counter his opponent's new winning strategy]].
* NewRulesAsThePlotDemands:
** 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 RuleOfCool, 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.
* NietzscheWannabe: 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. ([[http://www.yu-jyo.net/001/001.shtml In the Japanese, at least.]]) No better way to paint yourself a villain immediately, aye?
* NoKillLikeOverkill: 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 [[ForTheEvulz 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 [[WhatTheHellHero Tea hadn't stopped him]]. Note that this is during a special duel where ''you actually feel the pain of attacks''.
%%* NobleDemon: Seto Kaiba.
* NonHumanUndead: 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.
%% ** Another example are Bonz's monsters brought back from the grave.
%% * NotADate: Anzu/Tea goes on one of these with the Pharaoh.
* NotDisabledInVR: In the Virtual World FillerArc, 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.
* NotJustATournament: Virtually ''every'' TournamentArc, 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).
* NotTooDeadToSaveTheDay: Yugi gets help from all his [[TakenForGranite petrified]] friends and Kaiba) in his head before playing his last turn in the duel against Noah.
* ObviousTrap: 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.
%% * OffModel: Several moments. These actually make some of the more threatening characters ''even scarier''.
* OffscreenMomentOfAwesome: 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.
%% * OhCrap: Being on the receiving end of a spell, trap, or ability that they [[DidntSeeThatComing didn't see coming]].
%% * OlderIsBetter: The older your magic, the better it is.
%% * OlderThanTheyLook: Yugi.
* OddlyNamedSequel: ''Anime/YuGiOhGX''; ''Anime/YuGiOh5Ds''; ''Anime/YuGiOhZEXAL''[[note]]pronounced "Zeal" in the Japanese[[/note]], ''Anime/YuGiOhArcV''.
* TheOnlyOneAllowedToDefeatYou: To the point where Kaiba throws a hissy fit upon learning Yugi has 'allowed' someone else to defeat him in Season 4.
* OutrunTheFireball: At the end of the Virtual World arc, Kaiba presses a BigRedButton, sacrificing the greater part of his blimp to accomplish this.
%% * OrphanageOfFear: According to Kaiba, at least.
* OvertookTheManga: The Virtual World, Doma, and KC Grand Prix arcs were made because of this trope; the anime overtook the manga and had to create original content while they waited to catch up.
* ParentalAbandonment: Mai lost her parents at a young age.
%% * ThePasswordIsAlwaysSwordfish: Pegasus isn't very password-savvy, is he?
%% * PensieveFlashback: The Kaiba brothers experience these in spades during the Virtual Nightmare arc.
* PhantomZone: The Millennium Items each can transport the area immediately surrounding the user (and anyone else in it) to the Shadow Realm, an AlternateDimension 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 SoulJar. (Yami Marik does the former, Pegasus does the latter.)
* PhantomZonePicture: 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.
* PinballScoring: 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.
%%* PintsizedPowerhouse: Yugi.
* PlotTumor: Originally, the manga was not about any specific game, much less a single card game. Here non-Duel Monsters games are few and far between.
* PoweredByAForsakenChild: Creating the Millennium Items required a sacrifice of 99 human lives.
* PowerLevels: Monster cards have them in the form of Attack (ATK) and Defense (DEF) points.
* PowerMakesYourHairGrow: When Yugi, Bakura, and Marik become possessed by the spirits of the Millennium Items (or in Marik's case [[spoiler:his Superpowered Evil Side]]), their hair gets even more ridiculous than usual.
* ThePowerOfFriendship: This is the intended main theme for the series.
* PowerTrio
** BeautyBrainsAndBrawn: Shizuka/Serenity, Anzu/Tea, and Mai.
** BlondeBrunetteRedhead: Mai, Anzu/Tea, and Shizuka/Serenity.
** FreudianTrio: The Doma arc.
*** TheKirk: Yugi/Yami
*** TheMcCoy: Jounouchi
*** TheSpock: Kaiba
* PragmaticAdaptation:
** The Millennium World arc in the anime. Since not everything in a book will work in a show, the tabletop RPG was simplified, and Seto's battle with the Pharaoh took place just before Zorc awoke rather than after his defeat. In exchange, Kisara and Yugi's friends got more to do, and the consequences of Yugi's wish for friends was brought up as well.
** The ''Dungeon Dice Monsters'' arc 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. 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 TykeBomb, having a HeelFaceTurn 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.
* PrestigiousPlayerTitle: ''Duel Monsters'' players are called "Duelists".
%% * PrincessesRule: Princess Adina, ruler of Simlow, in Kaiba's virtual world.
%% * PromotionToParent: Seto Kaiba looks after his little brother after their parents die.
* ProtagonistCenteredMorality: 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.
* PsychicPowers: The Millennium Items give their owners a variety of psychic powers, depending on the item. Examples include [[MindRape mind raping]], locating and identifying other Millennium Item holders, [[{{Telepathy}} mind reading]], [[JourneyToTheCenterOfTheMind visiting someone's mental landscape]], [[SpiderSense seeing the future]], and [[BodySnatcher possessing other people]].
* PurpleIsTheNewBlack: The Shadow Realm is depicted with some swirls of midnight blue or black but mostly purple.
* PutOnABus:
** Bakura doesn't appear in any anime-original arc.
** Bandit Keith, who, after losing his duel with Yugi, is never mentioned in the story again.
* QuestForIdentity: The pharaoh is trying to find out who he is and regain his lost memories.
* RageQuit: 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.
* RapidFireTyping: Seto Kaiba often utilizes this whenever he's operating or hacking into a computer.
** Parodied in ''WebVideo/YuGiOhTheAbridgedSeries'':
--->'''Computer''': It looks like you're just pressing the same buttons over and over.
--->'''Kaiba''': That's because I learned how to [[HollywoodHacking hack]] by watching old episodes of ''Franchise/StarTrek''!
* TheReasonYouSuckSpeech:
** 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.
%%* RecapEpisode
* RecognizableBySound: In the Virtual World arc, Noah plays Serenity's screams into the tunnel where the rest of the gang are. Joey instantly recognizes it.
* RedemptionEqualsDeath: Sort of. [[spoiler:Noah Kaiba]] gains a body like he originally wanted, then puts himself back InsideAComputerSystem to save the others out of guilt. So, not dead but close to it.
%% * RedEyesTakeWarning: Hey, did [[ShrinkingViolet Yugi's]] irises just turn red? [[SuperPoweredEvilSide Better start running.]]
* {{Reincarnation}}: Gets rather complicated. [[spoiler: 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 EpilepticTrees is that [[NiceGuy Ryou]] is something similar in regards to the ancient BigBad 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.
* RoadSignReversal: Marik {{Body Surf}}ing 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.
* RousingSpeech: 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.
* RousseauWasRight: Numerous bad guys, including [[spoiler: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.
%%* RuleOfEmpathy
* RuleOfSymbolism: The author intended to have the cards represent the character and personality of their users.
%% * RuleThirtyFour: Usually done with [[BlackMagicianGirl Dark Magician Girl]], Tea/Anzu, and Mai, but other instances exist.
%% ** Most notable is what the Crump v. Tea duel in the Virtual World arc spawned.
%% * SadlyMythtaken: An Ancient Egyptian card game, for starters...
* SaveSat: 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.)
* ScrewDestiny:
** 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 [[TournamentArc Battle City Arc]]. ScrewDestiny, I have money!
*** He also changes the future itself by following his instincts and [[spoiler:sacrificing his ancient god card to summon a Blue Eyes White Dragon to attack and win his game against Ishizu, 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.
* ScrewTheRulesIHaveMoney: The GagDub is the TropeNamer.
** 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.
%%* [[ScrewTheRulesIHaveSupernaturalPowers Screw The Rules, I Have Supernatural Powers!]]
%% * SculptedPhysique: Many of the mons.
* SealedEvilInASixPack:
** 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).
* SelfMadeOrphan: Kaiba has a [[ParentalAbandonment long]] [[PromotionToParent history]] of [[OrphanageOfFear these]] [[AbusiveParents kind]] of [[SelfMadeOrphan tropes]]. Also Marik.
%% * SensitiveGuyAndManlyMan: [[ShrinkingViolet Yugi]] and [[TheStoic Yami]], respectively.
* SeriousBusiness: 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.
%% * SexyWhateverOutfit: The Dark Magician Girl wears a sexy RobeAndWizardHat.
%% * SharingABody: Yami and Yugi. Dark Bakura and Ryou. Dark Marik and Malik.
* ShapeshifterGuiltTrip: Dartz, by projecting the voices and faces of Yugi's soul-stolen friends onto his Mirror Knights, intimidates Yugi into not attacking.
* ShipTease: Rebecca kisses Yugi early on in Season 4. Cue LuminescentBlush (and he had an awkward expression on his face before she kissed him).
* ShoutOut: Both the card game and anime series feature cards based on Konami's ''VideoGame/{{Gradius}}'' and ''VideoGame/MysticalNinja'' series, and even one that references ''Franchise/MetalGear''.
** First episode, take a look at the shelf that Yugi covers up just as he answers the phone call from Kaiba. Even ''VideoGame/SuperRobotWars'' can find its way into a show about a children's card game.
** ''Yu-Gi-Oh!'' references ''Manga/{{Dragonball}}'' 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 TotemPoleTrench replicates a similar scene in ''Dragonball'', where Goten and Trunks use a similar tactic to get into a tournament.
** [[http://www.youtube.com/watch?v=YS6wcAzXhlc One of Pegasus's toons sure loves]] [[Franchise/CrashBandicoot 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 ''WesternAnimation/{{Jem}}''.
** In the dub for episode 95, a movie Marik sees on TV in the outside world has the line, "[[Film/PeeWeesBigAdventure Sorry Dottie, I'm a loner. A rebel.]]"
** In Joey's duel with Siegfried he says, [[Series/PressYourLuck "C'mon, big bucks no Whammy's!"]]
** In Joey's duel with Solomon/Grandpa: [[Series/FamilyFeud "Survey Says!"]].[[note]] This is also a BeamMeUpScotty, as the correct version is "Survey ''said''".[[/note]]

** Logically it should be Malik, which preserves his MeaningfulName 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.

** SplitPersonalityMakeover: 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.
%%* StepfordSmiler: [[UncannyValley Ryou Bakura]].
%% * StockForeignName: Vivian Wong.
* StoryArc: Duelist Kingdom, Legendary Heroes, Battle City, Noah's Virtual World, Battle City Finals, Doma, the Kaiba Corp Grand Prix, and Millennium World, with a MythArc spanning all of these arcs.
* StrongerWithAge: 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.
* StrawNihilist: "Weapons will not disappear and humans will not stop fighting. Thus, this world might as well be destroyed." -- Amelda in episode 166
* SuddenSequelHeelSyndrome: Season 4 turns Mai Valentine into an angst-ridden member of a villainous biker gang. It turns out she was tricked into HeelFaceBrainwashing by Dartz.
* SuggestiveCollision: Happens to [[JustFriends 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, [[ShipTease Mai thanks him for saving her and calls him an "action hero."]]
* SunglassesAtNight: Bandit Keith wears his sunglasses even in a dark cave.
* SuperpoweredEvilSide: Various characters' Yami versions, including the early appearances of Yami Yugi, who was more like TheUnfettered.
* {{Synchronization}}: Between the duelists and their cards, to some extent. Showcased when Yugi's grandfather Sugoroku actually has a heart attack when he loses.
* TakeOverTheWorld: Both Marik and Yami Bakura want to do this by usurping the pharaoh position from Yami Yugi, mostly as {{revenge}} for [[ItsPersonal personal]] beefs they have with him.
** [[spoiler: 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 [[spoiler: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 [[OmnicidalManiac every living thing on the planet]]. [[spoiler: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.
* TakingTheBullet:
** Kisara [[spoiler: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.
%%* TankGoodness
* TheTapeKnewYouWouldSayThat: 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... [[BuffySpeak thing.]]
* TarotMotifs: Inevitable, considering the [[SeriousBusiness 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 TheFool.
** Ishizu is the High Priestess.
** Téa is the Empress.
** Kaiba is TheEmperor.
** Shadi is The Hermit.
** Malik is The Heirophant.
* TattooedCrook: BigBad Marik Ishtar has a large tattoo covering his back and he is the leader of his own criminal organization. [[InvertedTrope 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 itís similar, and the dub changes it to a tattoo.
%% * ThemeDeck: The card game is the Trope Namer.
%% * ThereAreNoTherapists: Several characters would be better off with professional help, most notably the villains.
%% * TheyWereHoldingYouBack: Dartz's recruitment method.
* ThirdEye: 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 [[BodySurf possessed]] by Marik.
* TookALevelInBadass: 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 [[TheChick 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 [[BigBad Marik]].
* TooManyMouths: Slifer the Sky Dragon has two.
%% * {{Toon}}: Pegasus's Toon Monsters.
%% * ToonTown: Pegasus's Toon World card.
* TournamentArc: And how. The only arc two arcs that ''aren't'' tournaments are Waking the Dragons and Dawn of the Duel.
%%** Only with the second series anime, of course.
%% Which is the only thing this page is concerned with...
%% * {{Tsundere}}: Mai Kujaku/Valentine and Jonouchi/Joey.
* TraintopBattle: 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.
%% * TraumaCongaLine: Happens several different times, to several different characters.
* TriangRelations: 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.
%% * TroubledButCute: Early childhood Seto Kaiba. Also early childhood Malik.
* TruthInTelevision: 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 GameBreaker 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.
* UngratefulBastard: 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.
%% * TheUnfettered: The darker Bakura, Malik's manifestation of pent-up resentment, Gozaburo Kaiba, and to an extent Seto Kaiba
* UnstoppableRage: Specifically, after Yugi's soul is taken by the Orichalchos, and Insector Haga/Weevil Underwood ''[[BullyingADragon taunts]]'' the now rather unstable Yami by tearing up a card in front of him after claiming it contains Yugi's soul, just "[[MoralEventHorizon 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 [[NoKillLikeOverkill long after]] Haga/Weevil's life points have hit zero. He would've kept going too, if Anzu/Tea hadn't stopped him. [[http://www.youtube.com/watch?v=uYx_sJRmgeY Here's the scene]]... Not pretty.
** There's (possibly deliberately) an added MeaningfulEcho -- 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.
%%* UtopiaJustifiesTheMeans: Dartz.
* VendorTrash: When the rules got more defined, a lot of the worse cards didn't have DeusExMachina powers anymore and were pruned, though some of them got updated versions that are useful.
* ViewersAreGoldfish: 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 ''Anime/YuGiOhGX'', right up until Pot of Greed got put on the real-life banned list [[RealLifeWritesThePlot and the anime suddenly stopped using it]].
* VoiceOfTheLegion: Marik's servants gain a double-voice when he is [[BodySurf possessing them]].
* VirtueIsWeakness: This is the moral position of antagonists (Kaiba, Mai, Malik) in the series until Yugi or Jonouchi, the EmbodimentsOfVirtue, defeats them.
* WaterfallShower: The first season has this due to the fact that players are camping outdoors at night while they play the tournament.
* WeCanRuleTogether: 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 TrueCompnions to [[TakenForGranite 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!
* WarriorTherapist: 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.
* WelcomeToCorneria: Both virtual realities suffer from this, despite how fleshed-out everything else in them is. {{Deconstructed|Trope}} in the latter, since Noah spent ''years'' trapped in his world and was driven mad by everyone saying the same lines.
* WhamLine: From episode 52:
--> '''Ishizu Ishtar''': And the young man who stands behind the pharaoh... Above his head is [[spoiler: the Blue Eyes White Dragon.]]
* WhatHappenedToTheMouse: Gurimo from the first two episodes of the Waking the Dragons arc. Once he's finished being MrExposition, 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 HeelFaceTurn.
** Also, the last time we saw Bones and his friends, they were put into the Shadow Realm by Yami Bakura. Nobody ever rescues them. They're dead in the original Japanese version.
* WhatTheHellHero: Rebecca does this to Yami when his reckless use of the Seal of Orichalchos results in Yugi losing his soul. 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.
%% * WhiteHairBlackHeart: Bakura and Marik--or, at least, their evil alter egos.
* WineIsClassy: In the original, there's a scene where Pegasus is drinking a glass of wine. For the dub, this got changed to [[FrothyMugsOfWater "the world's finest fruit juices"]].[[note]]Funny enough, this could still allude to it being wine. After all, wine is often made from fruit and would be considered the "world's greatest fruit juice" by some.[[/note]]
* WithFriendsLikeThese: Jonouchi is often the subject of mistreatment from Anzu and Honda, particularly in filler arcs. It reaches egregious levels in Dungeon Dice Monsters and the KC Grand Prix--though they support him just as often, particularly in the manga-adapted arcs and the Virtual World.
* WokFu: Yugi faces off against Vivian Wong inside a Chinese restaurant. His friends get distracted from their usual cheerleading routine by all the food.
* TheWorfBarrage: 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 [[spoiler:combine it with the Fang of Critias]] and win that way.
* TheWorfEffect:
** 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|Trope}} 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 [[TraumaCongaLine 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 [[HeelFaceBrainwashing brainwash her over to the villains' side]] because of it.
* WorldOfHam: Especially when two [[HamToHamCombat hams duel against each other]]. The Kaiba/Yami matches go UpToEleven compared to others because of their rivalry.
* XanatosGambit:
** 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 [[spoiler: 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 [[spoiler: his good half]] is destroyed instead. It's subverted at the last minute.
** Used in the final duel between Yugi and [[spoiler: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 [[spoiler:Atem's]] monsters. Had he been right (which he was), then Yugi had a plan in place to immediately counteract it.
%% * YouCantFightFate: Somewhat. Averted in Kaiba's duel with Ishizu.
* YouGottaHaveBlueHair: Some minor characters. Also, Yugi and Yami's hair has some purple in it.
%% * YouMonster: See the trope page quote.
* YouWouldMakeAGreatModel: Happens to Anzu/Tea, who is promised a chance to be a dancer like she's always wanted.
* ZenosRace: 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.
* ZergRush: 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.
* ZettaiRyouiki: Rebecca Hawkins manages to pull off a grade-A in her initial appearance. Also, she's twelve years old.
