Duel Masters

S02:E03 - The Fellowship of the Duel

Shobu, his mojo returned, begins practicing for the Duel Masters Battle Arena, the biggest Duel Masters event of the year. Dr. Root provides special battle armor so that Shobu and Boy George can Kaijudo duel without fear of injury but something goes wrong and Shobu looses control of the creatures he's summoned. Shobu later reads that a similar event happened to his father and that his father went out on a quest to gain better control and become a true Kaijudo Master, and so Shobu prepares for his own quest.
