Yugi and friends arrive at KaibaCorp Island where the Battle City finalists will compete in the ultimate dueling arena, the majestic Duel Tower that stretches hundreds of feet into the clouds! Get ready for the awesome four-person battle royal where any duelist can attack anyone else!

Marik ensnares Jonouchi in a Shadow Game where each duelist’s heart is linked with his monsters... literally! Every time a monster received damage, the duelist feels the pain instead! Can Jonouchi survive, much less win, a duel where he’s actually losing life points?

It’s the rematch we’ve all been waiting for! Yugi and Kaiba square off for the first time since Duelist Kingdom in front of thousands of ravenous fans for the right to challenge Marik! It’s time to duel!

While Kaiba combines the magnetic menace XYZ-Dragon Cannon for unmatched attack power, Yugi only has one lowly Queen's Knight to protect himself! Even worse, Kaiba has all the monsters necessary to summon Obelisk the Tormentor to finish Yugi off! Though overwhelmed and outmatched, nothing is going to stop Yugi from trying to summon his Egyptian God first!

Kaiba attacks with his mighty Blue-Eyes White Dragon, but Jonouchi has no monsters to defend with! Jonouchi’s luck has run out, so it’s time for him to rely on skill! Meanwhile, Anzu challenges Marik for control of the Millennium Rod, but will she survive against Marik’s mystical powers of great evil?

Jonouchi and Kaiba’s battle reaches its roaring climax with the result of the duel hinging on one final spin of Time Wizard’s wheel! Will Jonouchi take down his biggest headache and actually teach Kaiba a thing or two about being a true duelist?

It’s Obelisk the Tormentor vs... Obelisk the Tormentor? Yugi can’t strike Marik’s life points because Marik’s indestructible Egyptian God Slime resurrects every turn! And with every turn that passes, Marik is one step closer to taking down Yugi with a final strike from The Winged Dragon of Ra...

Marik’s The Winged Dragon of Ra has destroyed both Slifer the Sky Dragon and Obelisk the Tormentor! Will the combined force of all of Yugi’s monsters be enough to defeat an Egyptian God Card that terminated two other powerful Egyptian God Cards? The fate of the duel, and the world, hangs in the balance with the finale of the Battle City Tournament!

Confusion abound when enemies become friends... and friends become enemies! Yugi and the gang set off on a cross-country trek when they’re asked for help from a one-eyed former foe! But will they get to him in time, for he is being watched by a “friend” who may have joined the dark side...

Can this be?! Mai has joined the enemy! Wielding the sinister sorcery of Seal of Orichalcos, Mai unequivocally calculates to trap Jonouchi’s soul for Dartz’s malevolent master plan! Is she brainwashed, or is there some deeper reason for her unexpected transformation?

Taking advantage of the arcane abilities of Seal of Orichalcos, Mai coordinates her Harpie Ladies into devastating combat formations to whittle Jonouchi’s forces into worthless waste! With Jonouchi’s soul moments away from oblivion, is this the last we’ll ever see of him, or will a legendary guardian recognize Jonouchi as a true duelist?

With the potent powers of Claw of Hermos, Jonouchi transforms Time Wizard into an almighty... hammer? Dazed and confused, can Jonouchi master the uncanny abilities of his new card to pound Mai’s Harpie Ladies before they slash him to shreds? And even if Jonouchi wins, Mai’s soul will be sent into the ether! It’s a no-win situation!

Dartz launches the final phase of his plan by having his minions of Orichalcos Soldiers attack all around the world, leaving Yugi and gang with no one left to trust! With chaos running rampant, Valon separates Jonouchi from his friends for a final showdown with Mai’s heart on the line! How can Jonouchi beat Valon by himself when both Ryuji and Rebecca couldn’t even leave a dent in Valon’s armor?

Decked out in high-tech body armor and weapons, Valon is pummeling Jonouchi with punishing punches! Valon’s helmet also feeds him crucial data on Jonouchi’s monsters, allowing Valon to analyze and assess the optimum strategy to render Jonouchi’s forces obsolete! Can Jonouchi outthink the computer before he’s downsized into oblivion?

With his scientifically-advanced armor, Valon systematically dismantles Jonouchi’s every move! However, Jonouchi is ready to strike back with his own modern armory as he combines Claw of Hermos with Rocket Warrior to form a never-before-seen cannon with incredibly devastating capabilities! As Jonouchi fires the final obliterating blast, victory is in his grasp... or is there more to Valon’s techno tactics than meets the eye?

Jonouchi and Valon’s battle rages to its roaring climax as Jonouchi attempts to turn the duel around by augmenting the very same armor that Valon used against him! But is Jonouchi’s strategy just a pale imitation that’s never as good as the original? And there’s also no rest for the weary – after their duel is over, a new duelist is ready to pick up the pieces and battle the winner!

Broken and battered after his exhausting battle against Valon, Jonouchi can barely stand up, much less duel! However, he has no time to rest before he faces a fresh and determined Mai! Both their souls are once again on the line inside Seal of Orichalcos, but unlike last time, this duel is NOT going to end in a draw! Can Jonouchi make it two victories in a row, even if it means trapping Mai’s soul away forever?

Yugi and the gang have saved the world from Dartz and his Grand Dragon Leviathan, but they’re about to face their biggest challenge yet – How will they get home when they have no money?! Fortunately, Kaiba has a plan... but there’s a catch! It’s time for the KC Grand Championship!

Yugi is trapped inside the Duel Dome, and the only way to escape is by defeating the Duel Computer – a calculating contraption programmed with the skills of the world’s top duelists! Since the Duel Computer has access to thousands of cards to create a devastating deck, how can Yugi win when he’s forced to use an amateur deck that barely contains any spell or trap cards?

It’s the second match of the KC Grand Championship as Rebecca faces the kung-fu kicking Asia champion Vivian Wong! However, there’s more at stake than just winning the duel – Yugi’s heart is on the line, whether he likes it or not! At the other end of Kaiba Land, a couple of familiar former champions sneak into the tournament, only to find themselves facing a threat that sends shockwaves throughout all the competitors!

The first round is over, leaving eight duelists to compete for the right to face Yugi for the KC Grand Championship! Unfortunately for Jonouchi, his next opponent is Sieg Lloyd, the dashing duelist who defeated both Haga and Ryuzaki in one turn! Things may be bad for Jonouchi, but Kaiba has his hands full when all the rides in Kaiba Land go haywire! Can Kaiba find out who’s behind all the sabotages before the tournament is ruined?

Sieg activates Ride of the Valkyries, the same card that defeated both Haga and Ryuzaki at the same time! If that one card can defeat two duelists instantly, what chance does Jonouchi have all by himself? Jonouchi better have one last card to turn this duel around before Sieg’s Valkyries carry him off to Valhalla!

It’s Yugi vs. Leon for the title of King of Games at the KC Grand Championship! However, something sinister lurks in the shadows, for this duel is more than just getting the crown! Sieg’s greatest revenge is about to commence as his real master plan is unleashed!

Leon is Sieg’s younger brother, and he’ll avenge his family’s loss! Leon’s fairy tales are giving Yugi nightmares, but the worst is yet to come because Leon has Sieg’s mysterious and special card. Sieg claims the card will take down KaibaCorp, but how can one card instantly destroy what Kaiba spent years building up?

Golden Castle of Stromberg is infecting the world’s Duel Disks with a virus that will destroy KaibaCorp! If Yugi doesn’t destroy the card, the virus program can’t be stopped – but Golden Castle of Stromberg can’t be destroyed by traps or spells! How can Yugi destroy a card that was engineered for ultimate survival and optimal destruction? KaibaCorp is on the edge of bankruptcy in the conclusion of the KC Grand Championship saga!

Yugi and the Pharaoh are reunited, but the Pharaoh is powerless without the Millennium Puzzle! However, that won’t stop the Pharaoh from a final showdown against the bandit king Bakura – he departs for the notorious thief’s cursed village where the spirits of old are ready to tear the Pharaoh down! Yugi and pals have their own mission to help save the world, but little do they realize that their seemingly-innocent journey will soon have them risking their lives...

Zorc’s incredible shadow energies have resurrected the bandit Bakura and his Diabound! With a second chance at revenge, the bandit king has broken up the Pharaoh’s team so that he can divide and conquer them one at a time! With his horde of monsters hunting our heroes, will any of them survive to see another day?

The Pharaoh and his guardians are down to their last line of defense as Shada falls victim to Zorc! The Pharaoh desperately wants to summon the three Egyptian Gods, but he can’t without his Millennium Puzzle! Mankind’s last chance may lie with Shimon – he’s ready to turn the tables by calling forth a legendary and unstoppable obliterator!

Pharaoh Atem, Yugi and friends have defeated the bandit Bakura and Zorc, but the final test still awaits! Yugi must duel... Atem! As they set sail to the final dueling grounds, everyone realizes that after many years, this may be the final night Yugi and Atem have together...
