Back to the stage of battle...

Yu-Gi-Oh! The Darkside of Dimensions is a Yu-Gi-Oh! movie to commemorate the franchise's 20th anniversary. It was released in Japan on April 23, 2016, with other territories receiving the film later in the year. The US got the film on January 20, 2017. Kazuki Takahashi is the executive producer of the film and is in charge of the designs, script, and story, making this the first movie in the franchise with the direct involvement of its creator.

The movie takes place six months after the original manga in the Japanese version and one year after the anime dub in the West. With the Pharaoh departed, Yugi Mutou and his friends resume a normal lifestyle. However, all of that changes when they encounter a mysterious classmate, Aigami, who possesses a connection to the Pharaoh's homeland. Meanwhile, Seto Kaiba, having lost a powerful rival, begins a hunt for the Millennium Puzzle that draws him into conflict from both sides...

A two-part prequel manga, entitled Yu-Gi-Oh! TRANSCEND GAME, was released in the two weeks preceding the movie, explaining the Duel Links VR system, how it works, and what Kaiba hopes to achieve with it, while also contending with Sera and Aigami attempting to thwart his plans.


This movie provides examples of:

  • Aborted Arc: Jonouchi's quest for a better Duel Disk goes nowhere. By the end of the movie he's still trying to pay for one.
  • Abusive Parents: Aigami and Sera lived with an abusive man before Shadi rescued and raised them.
  • Adaptation Dye-Job: 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.
  • Adaptational Wimp: In the manga Jonouchi was an amazing fighter who clobbered Bandit Keith in a fight as well as a powerful duelist. The anime version of him was humiliated often, had more losses, and couldn't beat Bandit Keith or Kaiba in a fight, but still had impressive moments and wins in between. Darkside of Dimensions Zig Zags this; on one hand, Jonouchi does nothing of importance, is told he's worthless for failing to escape Aigami's dimension and has to be rescued, wears a dog suit like he did in the anime to help pay for a new duel disk, and doesn't get to fight or duel. On the other hand, the bullies attacking Aigami split as soon as he gets involved, and he does try to punch Aigami's lights out. The dub gave him a moment of awesome by changing the mechanics of Aigami's dimension and implying that Joey broke out on his own, if at the last second.
  • Aesop Amnesia: With Atem gone Kaiba has forgotten his want to bury the past and focus on the future, instead focusing on seeing and dueling him one more time no matter the cost.
  • All There in the Manual: The prequel manga explains the VR system, how it works, and what Kaiba hopes to achieve with it.
  • Almost Dead Guy: Shadi gives Aigami the Quantum Cube and some last advice, but is killed before he can finish it.
  • Ambiguous Situation: The movie ends with Seto successfully breaching through to the afterlife. He has Aigami's Quantum Cube, but the movie leaves it up in the air as to whether going to the afterlife made him dead as well, and whether or not he'll win against Atem when he finally duels him. Complicating matters further is that he leaves KaibaCorp in Mokuba's hands, suggesting he may not return right away, if at all.
  • Another Dimension: Aigami's Quantum Cube can trap people in other dimensions. Anyone not part of the dimension originally will die, and he wants to stop Kaiba and Yugi because if the Pharaoh is reborn into the world, he and the rest of the planners will lose their powers and be bound to the world they're in.
  • Arson, Murder, and Jaywalking: After talking about programming every card and strategy Atem could use, Kaiba finishes off the list by saying his perfectly-coiffed hair took the longest to render.
  • Art Evolution:
    • The characters have received redesigns to bring them in line with the current art style of Yu-Gi-Oh! ZEXAL and Yu-Gi-Oh! ARC-V.
      • They are also more in-line with Takahashi's current style, where the characters have much more rounded features and greater attention to fine detail (as shown in the Duel Art artbook by Kazuki Takahashi)
    • The card back designs have evolved from simply being black ovals on white to accurate representations of the current Konami-produced cards.
  • Artifact of Doom: The Quantum Cube can directly erase people from existence and send them to other dimensions. The dub has it as an eighth Millennium Item.
  • Asshole Victim:
    • The Kudaragi gang, who try to harass Aigami and end up being sent to a different dimension.
    • Shadi is this in a flashback. While he did take care of Aigami, Sera, Mani, and other kids he also told them about the Millennium Items, being the chosen one, and of worlds better than the one they inhabit, leading to them having messed-up worldviews, and had no problem with killing people to further his goals.
  • As You Know: Lampshaded twice. After Kaiba loads the pieces of the Millennium Puzzle into the machine that will reassemble it, the space station AI explains to him how the system has scanned each system in a 3D scanner while suspended in a zero gravity field, and by recognizing the patterns in the pieces and comparing them all at once, it will be able to put the puzzle back together in only a few hours.
    Kaiba: Don't you think I know that? I invented the blasted thing.
    AI: Affirmative, but my AI has recognized your affinity for being reminded of your genius.
  • Bait-and-Switch:
    • One scene has Kaiba apparently duel and defeat Atem, only for it to be revealed as a virtual simulation.
    • There's also a more subtle one, regarding Aigami's vendetta against Yugi and his friends. While he's watching the main characters chatting over ice cream, he makes vague mentions of revenge and eradicating evil, and that 'no one is more evil than him!' while focusing on a shot of Yugi. A few scenes later and the movie makes it clear that he wasn't focused on Yugi at all: his real target is Bakura.
  • Balance Between Good and Evil: According to Shadi, the Rod, Eye, and Ring are prone to evil, the Necklace, Scales, and Key are for justice, and the Puzzle has light and shadows to balance them out.
  • Balance Buff: Meta-wise. Yugi and Kaiba use their trademark cards like Gaia the Fierce Knight, Vorse Raider, Dark Magician, Blue-Eyes White Dragon, etc. However, they're variants of the originals that have stronger effects and sometimes higher stats, which makes them more useful in today's metagame.
  • Battle Aura: Dimension Summoning requires duelists to use their spirits to summon, resulting in battle auras and screams akin to Dragon Ball Z.
  • Big Bad Ensemble: While Aigami is the main villain of the movie by manipulating Yugi and trying to stop Kaiba to achieve his goals, his actions are only because of Kaiba trying to bring back Atem from the afterlife. Furthermore, the Millennium Ring corrupts Mani, and was responsible for Shadi's death, motivating Aigami. However, during the climax, it replaces both Kaiba and Aigami.
  • Big Damn Heroes:
    • When Aigami traps Jonouchi in another dimension, he's unable to escape and would have died if not for Atem saving him.
    • Yugi can't defeat the possessed Aigami until Atem appears and helps Yugi win the fight.
  • Big Damn Movie: Even bigger than the previous movies, since it's meant to re-conclusively end the original series.
  • Blasphemous Boast: Kaiba talks about how the world they live in is so poorly-constructed that he'd fire whoever was responsible, with some translations going as far as to have him say he'd kill whoever was responsible. In the official translation of Transcend Game he also talks about going to the afterlife to put an end to Atem, which could be interpreted as killing him as easily as dueling and defeating him.
  • Body Horror:
    • In Ryo's flashback to how he got the Millennium Ring, the artifact fuses into his skin and protrudes from under his chest.
    • Most of the people Aigami erases dissolve head-first.
    • At the climax, the Millennium Ring possesses Aigami and he turns into a horrifying monster with cubes for eyes.
  • Bowdlerise: In the dub the Kudaragi gang just bullies Aigami, while in the subs they bully him, sexually harass him, and comment on how cute he looks.
  • Broad Strokes: Officially, the movie takes place in the manga continuity. However, some character designs and personalities take cues from the anime, and a couple plot points foreign to the manga that the anime created (a virtual world being a thing, Kaiba knowing Atem's name, Kaiba's extremely advanced tech) are here.
  • Broken Aesop:
    • Kaiba spends much of the film in an obsessive state, trying futilely to see Atem while being told that Atem has moved on and isn't coming back, with Yugi recompleting the Puzzle to prove it. Throughout the movie Yugi and his friends have moved on from the loss, Yugi gives Kaiba a speech directly telling him to move on, and Atem himself takes the Puzzle to the afterlife with him. Kaiba then decides that if he can't bring Atem back, he'll meet Atem by going to the afterlife instead, leaving Mokuba to run his company in his stead.
    • In the manga and anime, the Ceremonial Battle was all about Yugi overcoming Atem in a duel to prove he had grown to the point he no longer needed his other self and was ready to be on his own. In this film, much of the film is spent building up the ideas that Yugi has grown as a duelist, and he and Kaiba need to move on with their lives and accept Atem isn't coming back. Then the possessed Aigami is about to deal the game-ending blow when Atem spontaneously returns to save Yugi and defeat Aigami, showing that Yugi does still need his help sometimes. Making this worse is a comment from volume 8 of the bunkoban manga about a canceled Yu-Gi-Oh versus GX movie, where Takahashi stated that reviving Atem, which he considered, would betray the theme of the original series.
  • Brought Down to Normal: At the end of the movie, due to Atem appearing in the physical world once more, Aigami, Sera, Mani, and the other planners lose their powers.
  • The Bully: Kudaragi leads a gang of them, and they harass Aigami early on before he sends them to another dimension.
  • The Bus Came Back:
    • The Millennium Puzzle being excavated out from the site of the Ceremonial Battle is a plot point. 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. Kaiba summons Obelisk the Tormentor to use against Aigami.
  • The Cameo:
    • Kisara appears for a single panel in Transcend Game, but not the movie itself.
    • The Ishtars' only appearance is in a flashback to the Ceremonial Duel.
    • Some manga-only characters, such as Mr. Karita and Mr. Clown, cameo early on.
    • Ryuzaki and Haga cameo together at Kaiba Land.
    • Scott Irvine cameos in Transcend Game and the movie.
  • Canon Foreigner: Aigami, Sera, Mani, and the Kudaragi gang are all movie-exclusive.
  • Characterization Marches On: If his graduation speech is anything to go by, Yugi has taken his schoolwork more seriously than he used to. He also isn't as invested in Duel Monsters as he used to be, only picking up his old deck because Kaiba demanded a rematch.
  • Children Are Innocent: Shadi sees this as a reason for giving the Plana their powers, as children are not yet corrupted by the world and can see things adults can't.
  • The Chosen One: Shadi saw Aigami as an equal to Yugi, and he, Sera, and Mani were instructed about the Millennium Items and other dimensions as a result.
  • Conflict Killer: The Millennium Ring displaces both Kaiba and Aigami as antagonists, possessing the latter and serving as the final opponent.
  • Conspicuous CG: The Egyptian Gods, several of Kaiba and Yugi's monsters, Kaiba's machines and plane, and Aigami's cubic monsters are all 3D CG creations.
  • Continuity Lockout: Since the movie takes place after the series' end, it assumes you've either read the manga or watched the anime. At the same time, however, the movie largerly avoids making references to the plot of the series itself, other than the final Duel between Atem and Yugi. This was done presumably as to not conflict too much with the timeline of the anime, which has several major differences with the manga and is the medium the majority of movie-watchers are probably familiar with.
  • Continuity Nod: The prequel shows that Kaiba has a gallery showcasing all of the previous versions of the Duel Disk, even the "thrown" model that was only used in Duelist Kingdom.
  • Cool Airship: In Transcend Game, many guilds in KaibaCorp's VRMMORPG ride one of these to face down other guilds riding other cool airships. Kaiba gets his own personal Cool Airship that can be summed up as "rocket-powered Blue-Eyes White Dragon head".
  • The Corruption: The Millennium Ring brings out the darkness in Mani and Aigami's hearts, leading them to try and kill Ryo Bakura even after he explains that he didn't kill Shadi.
  • Cosmetically Advanced Prequel: The technology created by Kaiba in this film, particularly his new Duel Disk, surpasses anything shown in the Yu-Gi-Oh! sequel series up to ARC-V.
  • Creepy Child: In the prequel manga Sera has knowledge beyond her years, and claims to hear voices from the netherworld. She's also a skilled manipulator, challenges Kaiba to the technological equivalent of a Shadow Game, and is working with Aigami. In the movie itself, though, she's a hero and tries to stop Aigami's path to darkness.
  • Darker and Edgier: 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.
  • A Day in the Limelight:
    • Kaiba is the main character of the film, even featuring more prominently in the poster than Yugi. Transcend Game takes it even further, as Yugi and his friends don't appear at all.
    • The film also doubles as one of these for Yugi, who is able to step out from under Atem's shadow and away from his guidance for the first time since he left.
  • Deadly Euphemism: Ryo Bakura's father was 'lost that day' (dub) after putting on the Ring and getting attacked by Yami Bakura's shadows.
  • Death Is Cheap: Almost everyone killed or banished to the other dimensions returns by the end of the movie.
  • Demonic Possession: Mani is briefly possessed by the Millennium Ring. The Millennium Ring forcibly possesses Aigami near the climax, setting up the final duel of the movie.
  • Deus ex Machina: Near-literal examples when Kaiba spontaneously summons Obelisk against Aigami when he's on the ropes, and in Yugi and Kaiba's tag duel against Aigami Atem returns to save the day when all is lost.
  • Diabolus ex Nihilo: The climax has the Millennium Ring corrupting others, and bonding with Diva to create a reality-warping monster, but how it does so with Zorc and Yami Bakura gone is never explained.
  • Dismantled MacGuffin: Aigami steals two of the Millennium Puzzle pieces so Kaiba can't complete it.
  • Distressed Dude: Kaiba captures Aigami and takes him to Kaiba Land to duel him for the missing Puzzle pieces.
  • Dub-Induced Plot Hole:
    • The movie takes place after the anime in the west, turning Kaiba not being at the Ceremonial Duel into one of these. (He was there in the anime but not in the manga.)
    • Some exposition and metaphysical dialogue is cut from the dub, mostly involving Aigami's powers and motives.
  • Dub Name Change: The English dub aligns with the 4Kids dub names as opposed to the manga names for the sake of familiarity, despite the movie following the manga continuity closer. However, promotional material indicates that the English dub will be treated as being in the continuity of the anime, justifying this.
    • Kudaragi's name was changed to Scud.
  • Evasive Fight-Thread Episode: Yugi and Kaiba's duel is inconclusive, with Yugi apparently wiping him out, Kaiba somehow hanging on, and Aigami interrupting it before it can conclude. The movie also ends just before Kaiba and Atem duel.
  • Expendable Alternate Universe: The movie opens with shots of multiple parallel Earths being disintegrated by a golden light as it cuts to the Earth the movie takes place on.
  • Expy: Aigami is one to Ryo Bakura, having transferred to Yugi's class under mysterious circumstances and possessing mysterious powers. Ryo is even shown befriending him in pre-release screenshots, highlighting the similarities.
  • Fake Memories: Aigami altered the memories of everyone in Domino City, implanting the notion that he was a new student at Domino High School.
  • Fanservice Pack: Due to a combination of improved animation, tweaked art style, and the characters being slightly older.
    • Yugi is noticeably taller and more mature-looking, with more of a bishounen vibe. His eyes have also changed shape.
    • Kaiba is now sporting a tighter-fitting shirt which shows off a very well-developed chest and abs.
    • Anzu has a slightly different (and more flattering) hairstyle, more adult facial features, and wears tighter/more revealing clothes. She has also gained at least three cup sizes, with a corresponding increase in bounciness.
  • Four Lines, All Waiting: Many plot threads happen simultaneously, as well as flashbacks, resulting in many abrupt scene changes.
  • Fun with Acronyms: The first letter of the names of the new Magician Girls, Berry, Lemon, Apple, Choco, and Kiwi, spell out the word "BLACK", as in, Black Magician Girl, Dark Magician Girl's Japanese name.
  • Gonk: Two of the Kudaragi gang members, particularly their leader, have nonstandard or ugly designs.
  • Good Colors, Evil Colors: At first, Aigami's powers utilize a golden light. Once the Millennium Ring corrupts him and Mani, his powers turn a shadowy purple instead.
  • Happy Ending Override: Both the manga and anime ended with a conclusively happy ending, but six months later, trouble is afoot again. Seto Kaiba refuses to let go of the Pharaoh and instigates most of the movie's plot by his obsessive desire to reassemble the Puzzle, while he, Yugi, and his friends are menaced by Aigami, who's determined to kill Kaiba and Yugi if need be to stop the Puzzle from being completed.
  • How Much More Can He Take?: After three physically exhausting duels against Aigami and Kaiba in a row, one of which is a Shadow Game, Yugi finally reaches his limit and is about to lose until Atem saves him.
  • Insistent Terminology: In the Japanese version, Yugi continues to call Diva "Aigami-kun" long after the ruse is dispelled.
  • Lighter and Softer: 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 Dark Bakura going on a murderous rampage.
  • Living MacGuffin: The Pharaoh leaving sparked the Plana's powers, and him returning will cause them to lose their powers.
  • Long-Runner Tech Marches On: Back in the original series, the best Duel Disk technology ever progressed was with plain old Solid Vision, which was just hologram technology for monsters. Fast forward to Dark Side of Dimensions, which chronologically takes place just six months after the manga ends, and Kaiba Corp. suddenly has super-advanced VRMMOsnote , supercomputers, and cloud-based technology evocative of real-life modern day. Even the designs are streamlined to match the modern-day perception of "futuristic".
  • Made of Evil: The Millennium Ring is so evil and powerful that even after Zorc and Yami Bakura are gone, it turns Mani evil, corrupts Aigami with its power, and tries to make them kill Ryou.
  • Magic from Technology: Kaiba's VR tech, when combined with his own brainwaves, is so advanced that it can transcend dimensions, including breaking into the afterlife.
  • Magikarp Power: When Sera duels Kaiba in the latter half of the prequel, Sera kicks off with her ace monster, an 8800 Pulse beatstick. Kaiba brings out his ace, the iconic Blue-Eyes White Dragon, which has a Pulse of... 3000. Sera moves in immediately and blows up Blue-Eyes, but Kaiba simply laughs at it; not only does Blue-Eyes survive and not a scratch is left on Kaiba, its Pulse power-leaps to 19900 and curbstomps Sera.
  • Manipulative Bastard: In the prequel manga, Sera manipulates Kaiba by playing to his insecurities about the Pharaoh and his own skills, saying he'll never become the duel king—but if he links with the voice she hears from the netherworld, perhaps he can do something. Kaiba attempting to do so nearly kills him, which is what she and Aigami were planning to begin with. Her character profile for the movie states that she advises Aigami on his mission while also befriending Yugi.
  • Mind Screw: 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 the afterlife. Aigami's Quantum Cube that originally belonged to Shadi, and how Kaiba can counteract it with his duel disk, are also never fully explained.
  • Misplaced Retribution: Aigami wants to kill Bakura because he believes he killed Shadi, while Yami Bakura is the one that actually killed him.
  • Muggles Do It Better: Kaiba's technology is so advanced it solves the Puzzle in 5 and a half hours, while it took Yugi eight years to solve it.
  • Mythology Gag:
    • Diva's goal to make a better world by eradicating evil from it is similar to Dartz's goal from the anime.
    • Yugi reaching his limit after three consecutive duels is similar to Mai's Victory by Endurance against Jonouchi in season 4 of the anime, where he was exhausted after a physical duel against Valon and lost to Mai from fatigue.
    • The flashback to the Ceremonial Duel uses the characters' old hairstyles and eye designs, as well as the anime's coloration for their outfits.
  • Near Villain Victory:
    • In the prequel manga, Sera would have manipulated Kaiba into accidentally killing himself had Mokuba not been near the power main, letting him shut it down before it was too late.
    • In the final duel, the possessed Aigami has defeated Kaiba and whittles down Yugi's LP and strength, to the point of almost dissipating. Then Atem enters the scene and helps Yugi summon Palladium Oracle Mahad to defeat Aigami and the Ring.
  • New Rules as the Plot Demands: The rules of Dimension Dueling are vague and never fully fleshed out, allowing the duelists, Aigami in particular, to make moves that seem rather random at times.
  • New Transfer Student: Aigami transfers to Yugi's class under mysterious circumstances.
  • Nice Job Breaking It, Hero!:
    • Most of the problems in the movie can be directly traced back to Kaiba and Shadi. Kaiba's excavation team finds the pieces of the Millennium Puzzle, leading him to his obsessive quest to duel the Pharaoh, while Shadi gave Aigami his cube, his powers, and a very twisted worldview, and also gave Ryo the Ring.
    • It's revealed Yugi sending the Pharaoh back to the afterlife led to Aigami and his group gaining their powers, which leads to most of the movie's primary conflict.
  • No-Nonsense Nemesis: Aigami tries to disintegrate Kaiba almost immediately, but is repelled and forced to duel him instead.
  • No-Paper Future: Kaiba uses a completely virtual deck, while Yugi still uses physical cards.
  • Older and Wiser: Yugi has evidently matured a great deal, while physically looking older as well.
  • Once More, with Clarity!: While spying on Yugi and friends Aigami has a brief flashback to what happened in Egypt years ago, but it isn't until halfway through the movie that we see what happened in full.
  • One-Winged Angel: The Ring-possessed Aigami turns into a horrifying monster with cubes for eyes.
  • Out of Focus: Jonouchi, Honda, and Anzu don't do much but act as support for Yugi. Bakura, on the other hand, is important to Aigami's backstory.
  • Plucky Comic Relief: Jonouchi and Honda are mainly used as this; there's an entire montage of bad stuff happening to Jonouchi on the way to school.
  • Posthumous Character:
    • Despite passing into the afterlife, Atem features heavily in the plot, as Kaiba's goal is to resurrect and duel him, the Plana can't be banished without him, and Aigami's goal is to prevent his return. And he does appear in the climax, taking over for Yugi for the final move.
    • Dark Bakura is seen in a flashback of how Ryo got the Millennium Ring.
    • Shadi is only shown in flashbacks and is revealed to have taken care of Aigami, Sera and other struggling children in Egypt.
  • Power Levels: Unlike in actual Duel Monsters, KaibaCorp's dueling VRMMORPG bases the strength of a Monster on that of the power of the brainwaves outsourced by the player. As a result, the numbers can get pretty arbitrary.
  • Properly Paranoid: Ryou Bakura finds it difficult to relax with his friends knowing Aigami can make people vanish, and could be watching them as they speak. He is watching them as they speak.
  • Reality Warper: Aigami and the Plana are low-level versions of this, being able to teleport, send people to other dimensions, and travel between dimensions themselves.
  • Retcon:
    • The Puzzle originally fell in a complete piece, but in the movie it explicitly shatters as it falls, and assembling its pieces is a major plot point.
    • Bakura's father got the Millennium Ring from Shadi instead of from an antique shop in Egypt, and was killed by it despite being alive in the anime and in the manga as curator of the museum, which allowed the Millennium World to happen. Bakura himself also tagged along for the trip, despite it being implied in the manga and stated in the anime that he got the Ring when his father returned.
    • Shadi's appearance is changed slightly, he raised Aigami, Sera, Mani, and the planners, and he has powers he's never had before in any continuity, such as wielding the Quantum Cube, which can directly erase people from existence and send them to other dimensions. He can also transfer his powers to others, but they will lose them if the Pharaoh is reborn into the world a second time.
    • In the manga it was stated pretty clearly that as long as Bakura didn't wear the Ring it couldn't do any harm, but in this movie it corrupts several people without the need to wear it, in Aigami's case without even needing to touch it.
  • Revenge: Aigami initially desires revenge on Bakura for Dark Bakura killing Shadi.
  • Russian Reversal: In the dub, Shadi says to Bakura's father that you don't possess the Millennium Ring; it possesses you.
  • Sanity Slippage: Without Atem, Kaiba has regressed to a more villainous role to the point that he's willing to break into the afterlife and leave Mokuba behind to duel him again.
  • Screw the Rules, I Have Money!: Kaiba naturally. He's able to use KaibaCorp to keep tabs on everyone in Domino City, tracking their movements and keeping them under constant video surveillance without their knowledge, and he's able to use his personal forces to capture Aigami and force him into a duel for his Puzzle piece. It should also be noted that Aigami is essentially a kidnapper and a murderer and Kaiba apparently has no obligation to hand him over to the authorities.
  • Serial Escalation: Aigami first tries to prevent the Puzzle from being found and completed by stealing its pieces. When that fails, he tries to kill Kaiba, who plans to put the Puzzle back together to duel Atem. When that fails, he tries to kill Yugi, as killing him would ensure the Pharaoh had no vessel to return to, as well as kill Bakura to get revenge for Shadi. When that fails, the Millennium Ring possesses him and goads him to try and kill them both.
  • Ship Tease: There are a couple Yugi/Anzu moments throughout the movie, with them being physically close and having a Held Gaze before high-fiving.
  • Shut Up, Hannibal!: During their climactic duel, Yugi promptly shuts down Diva's attempt to make him join his cause by pointing out that, for someone who desires a world without hatred, Diva seems utterly driven by it, and that anyone that tries to create peace using hate will never succeed.
  • Sinister Surveillance: Thanks to Kaiba, nobody in Domino City can have citizenship without a Duel Disk. His VR system tracks players by their disks and brainwaves, making it possible for him to find Aigami even though he can teleport.
  • Skeptic No Longer: Kaiba, in the dub, was infamous for constantly denying any of the magic he encountered after season 1 and chalking it up to faulty holograms, illusions, and other excuses, only stopping towards the tail end of season 5. Even in the original manga, which this movie is mainly based on, Kaiba expressed utter indifference to magic at best and utter denial at worst, most prominently in Battle City note . In this movie, Kaiba actively acknowledging the existence of magic and trying to forcibly bring Atem back is an integral part of the plot. It's worth noting he does not believe magic, however, to be in any way not explicable and wieldable through science, and repeatedly manages to back this up, countering Aigami's Plana powers and in the end forcing his way into the afterlife.
  • Space Elevator: Kaiba has one that can take him from the ground to a space station.
  • Suspiciously Similar Substitute: Aigami, Sera and Mani are this to Marik, Ishizu and Rishid. Aigami's backstory is similar to Marik's, Sera takes Ishizu's role as a sibling who wants to lead him away from darkness, and Mani is like Rishid in that he's selflessly loyal to Aigami no matter what.
  • This Cannot Be!: Possessed!Diva's reaction to Atem returning to end the duel is sheer disbelief.
  • Time Skip: A minimal six months, but enough that lineart of Mokuba makes him look much older and preppier, with a short haircut and suit.
  • Time Stands Still: The Plana can freeze time for themselves and others, allowing for short conversations and longer flashbacks.
  • Too Dumb to Live: In the prequel manga, Seto is so focused on seeing and dueling Atem that he listens to Sera and tries to break into the afterlife using nothing but his own brainwaves and without any sort of protection. It would have killed him if Mokuba hadn't intervened.
  • Tracking Device: Kaiba's Duel Disks track and record characters' locations. He uses this feature to track down Aigami.
  • Unfinished, Untested, Used Anyway: Kaiba's machine to enter the afterlife, which he uses over Mokuba's protests that it's an untested prototype. It gets him where he wanted to go, but whether he can come back is left ambiguous.
  • Ungrateful Bastard: Jonouchi is the only one who stands up for Aigami when some bullies try to pick on him. Despite this, Aigami later banishes him to another dimension that would slowly kill him and calls Jonouchi worthless.
  • Viewers Are Geniuses: A lot of Aigami's motives and methodology in the Japanese version references quantum mechanics, a field of science that tends to be confusing and difficult to understand even to those that study it.
  • Villain Protagonist: Kaiba has become more antagonistic since the Pharaoh left, and the movie closely revolves around him. Much of the conflict in the movie is his fault, as he refuses to let anything stop him from dueling Atem. He also treats Yugi and his friends with an even worse amount of disdain, referring to Yugi as merely a vessel for the Pharaoh's soul.
  • Villain Teleportation: Aigami, Sera, and Mani can teleport via their Plana powers, letting them get to distant places instantly.
  • Villains Act, Heroes React: While Aigami and Kaiba are active in getting what they went, Yugi and his friends react to them doing things.
  • Visionary Villain: Aigami believes so much in Shadi's vision of a better world beyond dimensions that he thinks Yugi's world is static and has no meaning. The Millennium Ring takes his wish even further by trying to create a new world of darkness.
  • The Voiceless: The virtual Atem banters with Kaiba in the opening simulation, but the real Atem doesn't say a word.
  • What Happened to the Mouse?:
    • The Kudaragi gang's fate is never revealed even after other characters are freed from the dimensions.
    • Besides the Puzzle and Ring the other Millennium Items' fates are a mystery.
    • The Egyptian God Cards that were sealed along with the Millennium Items remain as unaddressed as the rest of the Items, except for Obelisk.
  • You Have Outlived Your Usefulness: This is presumably the reason why the Millennium Ring tries to get Aigami and Mani to kill Ryo.
