History Anime / YuGiOhTheDarkSideOfDimensions

** Kaiba's duel against the virtual recreation of Atem is similar to their first on-screen duel from ''Anime/YuGiOhTheMoviePyramidOfLight Pyramid of Light'', right down to the point where Kaiba has a three-headed Blue-Eyes Fusion Monster and raising its ATK to 9000.

* DarkerAndEdgier: The movie eclipses Pyramid of Light as the darkest one in the series, making this the darkest dub-related thing as well. This is most notable with the third English trailer, which is played completely straight and with a focus on drama, not duels.

** Kaiba's duel against the virtual recreation of Atem is similar to their first on-screen duel from the ''Pyramid of Light'' movie, right down to the point where Kaiba has a three-headed Blue-Eyes Fusion Monster and raising its ATK to 9000.

* ThisCannotBe: [[spoiler: Possessed!Diva's reaction to Atem returning to end the duel is sheer disbelief.]]

** Even outside of Dimension Duels, the movie uses the game's modern ruleset rather than Battle City's: players start with 8000 Life Points, each player can control 5 monsters and 5 Spells/Traps instead of just 5 cards total, and Fusion and Ritual monsters are physical cards with unique effects.

* LighterAndSofter: In contrast to the manga's frequent depictions of blood and death, characters are sent to other dimensions and bloodlessly attacked by shadows, though they can still die if not rescued, and Aigami's backstory involves [[spoiler:Dark Bakura committing murder in front of children]].

* InconsistentDub: An unusual example that applies to the original version but not the English dub. When monsters are summoned, the stat screen reads the name they have in the English TCG, even if that name is a DubNameChange from the Japanese OCG, rather than a translation of the latter. As such, the Japanese version has peculiarities like Yugi saying Black Magician and Metamor Clay Fortress while the screens read Dark Magician and Metamorphortress, and Diva referring to his monster as Direction World Super Emperor Indiora Death Volt and the screen calling it Indiora Doom Volt the Cubic Emperor.

* TranslationNod: The stat screens that appear when a monster is summoned read the English TCG’s DubNameChange for that monster on the display in all versions of the movie.

* AdaptationDyeJob: The Dark Magician's clothes are black and his hair is white, in contrast to the manga where his clothes are blue and red and his hair is blond and the second anime where his clothes are purple and he's fair-skinned. The Blue-Eyes White Dragon is also white instead of light blue with white highlights.

* AlternateContinuity: It was written as a sequel to the manga timeline and ''not'' the anime timeline, instead of starting the events of ''Anime/YuGiOhGX'', Kaiba was unable to let go of his obsession with beating Atem while acknowledging Yugi as a duelist due to being absent for the Ceremonial Duel. This results in the plot of the movie. The English Dub instead takes a BroadStrokes opproach.

** The Millennium Puzzle being excavated out from the site of the Ceremonial Battle is a plot point. [[spoiler:The Millennium Ring also returns.]]
** At the end of the original manga and anime, the Egyptian God Cards were presumed to have been either taken into the afterlife along with Atem or buried underground with the Millennium Items. [[spoiler:Kaiba summons Obelisk the Tormentor to use against Aigami.]]

* MugglesDoItBetter: Kaiba's technology is so advanced that it solves the Puzzle in 5 and a half hours, while it took Yugi eight ''years'' to do the same. (Potentially subverted in that Yugi was probably being tested by the puzzle at the same time, he was a child, and during the time of DSOD, the puzzle no longer has powers. Yugi solved the puzzle very quickly during his altercation with a possessed Bandit Keith in Battle City.)

* TimeSkip: A minimal six months, but enough that lineart of Mokuba makes him look much older and preppier, with a short haircut and suit.

** The stat screens that appear when monsters are summoned or do damage present the names that the monsters have in the English TCG rather than the Japanese OCG, even in the original Japanese version. For example, Yugi summoning Black Magician and Black Magician Girl will be accompanied with the labels "Dark Magician" and "Dark Magician Girl".

** Anzu has a slightly different (and more flattering) hairstyle, more adult facial features, and wears tighter/more revealing clothes. She has also gained [[MostCommonSuperpower at least three cup sizes]], with a corresponding increase in bounciness.

* MugglesDoItBetter: Kaiba's technology is so advanced that it solves the Puzzle in 5 and a half hours, while it took Yugi eight ''years'' to do the same.

* AnimationBump: In all the years of Yu-Gi-Oh anime, the artwork and animation has never looked as impressive and ''beautiful'' as it does in this movie.

** At the climax, [[spoiler:the Millennium Ring possesses Aigami and he turns into a [[http://vignette1.wikia.nocookie.net/yugioh/images/6/6c/Monster_Aigami.png/revision/latest/scale-to-width-down/640?cb=20160722195318 horrifying monster]] with cubes for eyes]].

* OhCrap: Aigami is rightly shocked when Kaiba summons [[PhysicalGod Obelisk the Tormentor]].

!!This page contains unmarked spoilers for the original Yu-Gi-Oh! [[Manga/YuGiOh manga]] and [[Anime/YuGiOh anime]].

* CanonImmigrant: Kaiba's Blue-Eyes White Dragon-modelen jet from the anime is worked into the movie, though its remodeled to be ''a bit'' more aerodynamic.

** Some exposition and metaphysical dialogue is cut from the dub, mostly involving Aigami's powers and motives.

** In fairness, it’s implied the reason Yugi took so long to solve the puzzle (and why anyone else was flat out unable to solve it until he came along) was that [[OnlyTheChosenMayWield the magic of the puzzle would only allow someone it accepted to piece it together.]] With the spirit of Atem gone, this magic presumably faded away.

* MindScrew: The other dimensions are very mindscrewy in appearance and function; anyone not part of them to begin with will disintegrate, and one such dimension is apparently [[spoiler:the afterlife]]. Aigami's Quantum Cube—and how Kaiba can counteract it with his new duel disk—are also given rather vague explanations that assume the viewer has an understanding of quantum mechanics.

* MugglesDoItBetter: Kaiba's technology is so advanced that it solves the Puzzle in 5 and a half hours, while it took Yugi eight ''years'' to to do the same.
