Yu-Gi-Oh! - Season 1

Yugi and friends take a break from honing their card-playing skills to watch Weevil and Rex Raptor compete in the Duel Monsters Regional Championship. When Yugi opens a package from Duel Monsters creator, Maximillion Pegasus, Yugi is forced to face him in the mysterious Shadow Realm, where all the monsters and magic are real.

Yugi gives up one of his own star chips so Joey can board the boat bound for Duelist Kingdom and duel to save his sister's eyesight. Meanwhile, Téa and Tristan stowaway to join their friends.

Once Yugi and his friends reach Duelist Kingdom, Pegasus announces that there are many strange secrets on the island which will make his ultimate tournament unlike any they've ever had. But when Weevil begins to use these mysterious new rules against Yugi in a duel, Yugi must not only figure the rules out, but master them if he's to survive!

After Yugi defeats Weevil's first wave of Duel Monsters, he's shocked to discover that Weevil has one last trick up his sleeve; a ravenous Great Moth that grows in power with every turn! Can Yugi find a way to destroy this winged beast before it destroys him?

Joey searches for a dueling opponent he stands a chance of beating when he finds himself courageously accepting a challenge from veteran duelist, Mai. But when Mai begins to demonstrate an unnerving psychic-like ability, Joey becomes totally flustered, leaving him no choice but to figure out Mai's secret strategy before falling victim to it!

The fisherman duelist Mako, the master of the Sea Deck, baits Yugi into a duel on his own Sea playing field for a home field advantage. Can Yugi adapt to these new settings to turn the tide of battle?

If Yugi is eliminated from the tournament, Kaiba Corporation's crooked Board of Directors will transfer control of the company from Kaiba to Pegasus! Kaiba's younger brother, Mokuba, challenges Yugi to a duel not only to protect his brother's company but to regain their honor! Is Pegasus successfully manipulating possible allies against each other?

Yugi must duel a magical doppelgänger of Kaiba, created from the greed and power lust Yugi wiped from Kaiba's soul. But with his best cards resting at the bottom of the ocean, Yugi must discover a new strategy if he's to survive fake Kaiba's powerful Blue Eyes White Dragon!

Yugi defeats the Blue Eyes White Dragon, but there are two more waiting in the wings! Will the real Kaiba reach Yugi in time to help beat this impersonator?
