He first appeared in Less is Morrison, when he met Ash, May, Max and Brock when his sandwich was rolling. Though May's Munchlax ate it, Ash was tempted to get a new rival, who was his match. Morrison battled with his Beldum and the battle ended in a draw. They both began to accept each other and battled Team Rocket by themselves to take Pikachu and Beldum back.
Eventually, he signed up for the Hoenn League and participated in battles. In one of his battles, the Beldum evolved and secured Morrison a victory. He emerged victorious, until he saw on a screen he would battle with Ash. Morrison was depressed, forcing the judge to make Ash a winner, but Ash convinced him to battle making him more confident. Though a close call, Ash won, but Morrison was glad that he fought bravely. He cheered for Ash against Tyson, even if Ash lost. In the end, Morrison departed away with Tyson.
