Legend of the Dragons
Although Yugi has defeated the mysterious Duelist, he has not regained his God Cards. The three who appeared in the middle of the duel said Yugi had to beat them before he could get the God Cards back and disappears. Rebecca and her grandfather, Professor Hopkins, seek Yugi out. They tell him about a new discovery made by a submarine investigation that uncovered evidence of a civilization, more than 10,000 years old, that was destroyed by monsters. This disaster coincides with the crisis in ancient Egypt 3,000 years ago which had been diverted by the king with no name. Monsters are beginning to crossover into the real world. It seems that the events that played out 10,000 and 3,000 years ago have come full circle again.
