After Battle City, Yugi has possession of all three Egyptian God Cards. In order to gain his memory, he needs to use these along with the Stone Tablet in Domino Museum. However, during a nightmare, the Gods and the Tablet are stolen, and Yugi's Memory remains as it was. Along with that, sightings of REAL duel Monsters have been seen around the world!

It turns out that an evil organisation is causing this Mayhem, and using the God's Power, and Souls of the innocent, they are able to bring monsters to life to take over the world! However, they need more souls to accomplish their ultimate goal, they need the soul of a Pharoh.

In order to gain souls of the Innocent, the Organisation challenge the player to a duel. But a special card must be played in order to take the soul. This card is called the Seal of Orachalcos.

When this card is played, there is no escape from a duel. The loser's soul is taken when this card is active. No effect of a Millenium Item can negate this effect because it was created before the Millenium Items, only a power similar can destroy it. As an added bonus, all monsters that the controller of this card owns gain a 500 ATK Boost!

Along with the Seal of Orichalcos, Three Legendary Dragons were created. Their power is immense and the gang use these cards to aid them in defeating the Doom Organisation.

Timaeus - Owned By Yugi

Hellmos - Owned By Joey

Critias - Owned by Seto Kaiba

These three cards can only be summoned when a player is in danger, and can only be used if the owner has a true Dueling Spirit and believes in the Heart of the Cards. They were frozen away in time, but the gang revive them and use them. But is this great power enough to stop the evil that threatens the world?

You gotta watch it to find out!
