Jaden finds out from Syrus that someone has been challenging students to Duels and stealing their Duel Disks. After Syrus lost his too, Jaden decided to face this bully at a bridge in the forest. His name was Tyranno Hassleberry, a new student in Ra Yellow. He had passed all his exams, but was stuck in Ra instead of Obelisk Blue, so he formed an army of his supporters and stole people's Duel Disks in order to show his power. Jaden faced off against his Dinosaur deck and made Hassleberry realize that using the same strategy to defeat his opponents will only make his friends get bored of him. Jaden beat him using his new fusion monster, Wildwingman, and Hassleberry gave the Duel Disks back to their owners. He decided to live in the Slifer dorm because he felt he could learn a lot about dueling from Jaden.
