Morrison is one of Ash's friends. He was defeated in the Hoenn Tournament by Ash.
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.
Metang is Morrison's favourite Pokémon. Though when Ash met Morrison it knew only Take Down, Beldum was able to defeat Pikachu. Later, in Saved by the Beldum, it evolved and defeated a trainer, ensuring Morrison's victory. In Choose It or Lose It!, Metang was a powerful match, but Ash's Glalie defeated it. Metang's moves are Confusion, Take Down and Meteor Mash.
Gligar was Morrison's fastest Pokémon. It battled with Growlithe in From Brags to Riches against a Marowak and Machamp and Gligar won. Later, Gligar battled with Ash's Pokémon in Choose It or Lose It!, it battled with Grovyle, defeating it, but was defeated in a draw with Ash's Swellow.
Growlithe is another Morrison's Pokémon. It battled in From Brags to Riches with a Machamp and a Marowak. It proved to be resistant, but was defeated by Marowak. Later, in Choose It or Lose It!, Growlithe battled Ash's Corphish, but since Morrison was depressed, it was beaten fairly easily. Its moves are Flamethrower and Take Down.
Steelix is Morrison's most powerful Pokémon. Steelix battled in Choose It or Lose It! with Pikachu and Torkoal, defeating them in a row. It proved quite offensive and defensive, but was defeated by Ash's Grovyle. Its moves are DragonBreath, Dig and Iron Tail.
