The three Egyptian God Cards are stolen! A terrifying new villain emerges! And, as if things couldn’t get any worse, real monsters begin to appear around the world, terrorizing the population! Can Yugi and the gang discover how these strange events are connected, much less solve them, before the planet is destroyed? It’s a whole new adventure as the world descends into chaos!

With Seal of Orichalcos, not only can Gurimo have ten monsters on the field at once, but each creature receives a power boost from Orichalcos’s malevolent energies! Yugi better find a way to protect himself against Gurimo’s super horde, for the loser of the duel will have his soul sealed away forever!

Not only is our world on the brink of apocalypse, but an entire domain of monsters is also on the verge of collapse! The guardians of both Earth and the monster domain must unite and fight against the largest terror they have ever faced, a malevolent menace whose body is miles in length!

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...

Kaiba returns to Duelist Kingdom for a showdown against Pegasus! Wielding his newest whacked-out Toon terrors, Pegasus is ready to repeat his previous victory against Kaiba! Will Kaiba discover the secret behind Pegasus’s strategies before he loses his soul, just like he did on his first trip to Duelist Kingdom?

Not only does Amelda’s mighty fiend gain attack points for every fiery monster on the field, but it can also take control of Kaiba’s monsters! With Amelda’s army growing while Kaiba’s squad whittles into nothing, will Amelda get his seething revenge, or will Kaiba be recognized as a true duelist and get aid from the monster domain?

On the way to Industrial Illusions, Yugi and friends are ambushed by a band of motorcycle thugs - until their favorite friend soars to the rescue on the wings of her Harpie Lady! Mai’s back to help Yugi take down Dartz and save the world from annihilation... or is a topsy-turvy twist in the works?

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!

Professor Hopkins has discovered startling connections between the world’s chaotic conundrums, the Orichalcos stones and an ancient lost civilization! However, before he can reveal his findings to Yugi, he’s kidnapped by Rafael! Yugi’s on the trail, but is this an elaborate plan to trap the Pharaoh?

Isolated on a steep mesa in Death Valley, it’s a Wild West showdown between Yugi and his fiercest challenge yet: Rafael and his group of guardian monsters! Rafael’s strong symbiotic relationship with his monsters won’t allow him to let a single one rest six feet under in the graveyard! Will Yugi be quick on the draw and break through his gang of guardians, or will Rafael show that he’s the new sheriff in town?

Dartz’s master plan is finally revealed, and capturing Yugi’s soul is the catalyst to reset the very essence of history! With humanity on the line, Yugi calls on the legendary strength of Timaeus, but when it’s not enough to crack Rafael’s defense of gargantuan guardians, will Yugi resort to desperate measures and go against everything he believes in to make the riskiest move of his life?

Using the awesome abilities of Seal of Orichalcos, Yugi grinds Rafael’s guardians into garbage... but he’s also slowly succumbing to the card’s evil influence! As darkness grows within his heart, Yugi’s monsters turn sinister! Yugi will do anything to win, including indiscriminately forsaking his precious monsters, but the consequences of his non-heroic acts may be his undoing!

Dartz has captured Yugi’s soul! Having betrayed his dearest friend, the Pharaoh sinks into the darkest depths of despair and loses his will to save the world! Broken and unmotivated, how will our heroes ever rescue Yugi, especially when Dartz has a duo of nefarious new recruits ready to eradicate them?

Divide and conquer - it’s a train ride to terror! A cross-country expedition turns tragic when Dartz’s new duelists separate Yugi from Jonouchi in order to capture their souls separately! Stuck in the middle of nowhere, can Jonouchi win without Yugi’s support against ranks of ravaging raptors? And can Yugi, in his greatest moment of weakness, pull himself together before he joins the other lost souls by taking the last train to oblivion?

While Haga sneakily infests and genetically manipulates Yugi’s monsters to metamorphose them into crude creepy crawlers, Ryuzaki’s prehistoric predators take a more forceful approach and run roughshod over Jonouchi’s forces! Nothing will stop Haga and Ryuzaki from quenching their thirst for revenge that’s been brewing since Battle City by capturing Yugi and Jonouchi’s souls!

Having lost the trust of Timaeus, Yugi can no longer use his guardian dragon against Haga’s insect invasion! Discouraged and confused, Yugi has lost his dueling instincts! As for Jonouchi, Ryuzaki’s deadly dinos have Jonouchi struggling to find a monster that has even the remotest chance of withstanding their relentless assault! Will Jonouchi realize that a certain iron knight, weighed down by his cumbersome armor, hasn’t unleashed his full power yet before he’s squashed into Jurassic juice?

The train derails and plummets into a chasm, leaving Yugi and Anzu totally lost in the Rocky Mountains! Not only do they have to make their way back to civilization, but Yugi is about to embark on his greatest spiritual journey yet when he meets the mysterious Ironheart! Yugi is on a vision quest where he must travel through a past of evil to find and conquer his greatest foe... himself!

Weakened by his journey into the dark reaches of his heart, Yugi is in no shape to duel... but Dartz doesn’t care! Dartz sends out his ancient annihilator Orichalcos Soldier to finish Yugi once and for all! Ironheart struggles to help him, but he may pay the ultimate price from a battle that started ten thousand years ago...

Valon is ready to take on the world and fight... for the heart of Mai? And the first adversaries standing in his way are Ryuji and Rebecca! Not only is it a two-on-one handicap match, but Valon’s armor monsters have zero attack points! All the cards appear to be on Ryuji and Rebecca’s side, but when there’s more to the armor than meets the eye, who really has the advantage?

Buckle your safety belts – it’s a duel thirty thousand feet in the air as Amelda squares off against Kaiba on top of an airplane flying at hundreds of miles per hour! If that wasn’t enough to make Kaiba airsick, the pilot’s missing, the autopilot is malfunctioning and the plummeting plane is on a collision course with a massive mountain!

Amelda dispatches his airborne arsenal Air Fortress Ziggurat, a mechanical menace that’s not only armed with countless cannons but can also summon a battalion of Robot Tokens! How can Kaiba defeat an endless rank of robots, much less a monster the size of the plane itself? He’s running out of time to think of a plan - the plane is minutes away from crashing!

Dartz has taken over KaibaCorp! The timing couldn’t be any worse - the only supercomputer in the world that can decipher the Atlantean hieroglyphics is housed within the four walls of KaibaCorp! Can Kaiba, with Yugi’s help, break into his own company which he’s protected with the latest in security technology? Not only is the company built to punish every unwanted intruder, but vicious monsters are hot on their tail, ready to feast on them!

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?

Not only is Jonouchi’s soul captured, but before this episode is over, another of our loved ones will also lose his or her soul! Also, it’s a rematch between the Pharaoh and Rafael – but this time, the Pharaoh doesn’t have Yugi to protect him! Is the Pharaoh still haunted by his devastating loss at the hands of Rafael? He better pull himself together, for Rafael is taking off the kiddie gloves and unleashing even more powerful guardians than before!

Rafael, unlike the Pharaoh, fully knows how to harness the powers of Seal of Orichalcos to his advantage to annihilate the Pharaoh while fortifying his own defenses! But as Rafael embraces the darkness within his heart, Rafael starts breaking his own bond with his monsters by destroying them for the greater cause! Rafael appears to be losing control and creating an opening for the Pharaoh’s counterattack, but Rafael has even more dreadful displays of terror in mind to finish off the Pharaoh

From the depths of darkness, Rafael calls forth Guardian Dreadscythe, a ravaging reaper that can never be defeated... for it resurrects automatically! As the invincible sickled stalker shaves off the Pharaoh’s life points every turn, how can the Pharaoh survive this onerous onslaught, much less rescue Rafael from the darkness feasting on his soul?

It’s time for the endgame! After discovering the location of Dartz’s secret base in the middle of the ocean, our heroes are on their way to stop Dartz once and for all –with the entire navy as their escort! However, Dartz’s island is magically guarded with thundering maelstroms and tornadoes that prevent anyone from approaching! Can they reach Dartz before he resurrects the lethal Grand Dragon Leviathan from its millennial slumber?

Dartz shows Yami and Kaiba the history of Atlantis, how the Orichalcos drove them into insanity, and how he lost his wife. In an attempt to save his people, Dartz made a contract with the Great Leviathan to use the Orichalcos to purge mankind, in order to restore "paradise." However, he was stopped by the three Legendary Dragons and former King Ironheart. Back in the duel, Dartz plays the second layer of the Seal of Orichalcos, Orichalcos Dueteros, and he uses his Mirror Knight Calling to summon his four Mirror Knights, each containing the souls of Yugi, Joey, Pegasus and Mai. However, if the Knights are destroyed, their souls may be lost forever.

Dartz plants the souls of our captured heroes into Mirror Knights to use them as puppets to fight the Pharaoh and Kaiba! How can the Pharaoh duel when attacking Dartz may force him to attack Yugi? Does he dare risk eliminating his best friend forever? Our heroes better beware, for this is the least of Dartz’s malevolent manipulations as his dark designs come to light!

It’s a multi-pronged attack as Dartz adds a third ring to Seal of Orichalcos, stopping the Pharaoh and Kaiba from doing... anything! Even when they manage to attack, Dartz’s Orichalcos Kyutora absorbs all damage! Furthermore, to add insult to injury, Dartz summons the thundering Orichalcos Shunoros to pound the Pharaoh and Kaiba into pancakes! It’s game over, for even the guardian dragons are little match against this battling behemoth!

Kaiba’s soul has been captured, leaving the Pharaoh all alone to fend for himself against the invincible forces of Dartz and the Orichalcos! Will his friends reach out from the beyond to give him one last fighting chance before the Pharaoh sinks into the inescapable depths of despair? For in the darkest time of need, hope still resides among the legendary dragons as they reveal their true identities...

Dartz calls forth Divine Serpent Geh, a sinister snake with infinite attack points! Yugi counters by joining the three legendary dragon knights into the mighty Timaeus the Knight of Destiny, but is that enough to combat a monster with limitless strength? As the great forces clash, the gateway opens for the final endgame as the world-devourer Grand Dragon Leviathan and the legendary Atlantis rise out of its watery grave!

It’s the brawl for it all! All the monsters of Earth join forces with the survivors of the monster domain for an epic showdown against Grand Dragon Leviathan with the fate of both worlds hanging in the balance! But the tide of battle is turning against our heroes as Grand Dragon Leviathan unfurls gruesome tentacles to snatch Yugi and his crew and absorb them into its body!

Grand Dragon Leviathan’s thunderous roars unleash hundred-foot tall waves worldwide to destroy every town and city on Earth and wash away all traces of humanity! How can Yugi’s simple soul stop the annihilation of the planet from the greatest natural disaster in history? Billions of lives are at stake in the thrilling conclusion where failure means extinction!
