Mick was a shy boy who didn't have too much confidence. One day, he encountered Pikachu that came falling from the sky and into his arms. It electrocuted him out of fright, and he assumed that, because it can use Electric attacks, it was the pre-evolved form of a Zekrom. He proceeded to show it off to his friends Glenn and Sean. However, Sean identified it as a Pikachu, and Mick left.
He then bonded with Pikachu and later met Ash, Iris, and Cilan. Ash taught Mick how to battle, letting him use Pikachu while Ash used Krokorok, and later Tepig. Mick was thrilled to have learned how to battle, and then returned to battle Glenn and Sean. The three of them had a Double Battle, with Sean and Glenn using a Scolipede and Seismitoad belonging to Sean's father, and Mick using Pikachu and Krokorok. Mick ended up winning the match due to Sean and Glenn constantly arguing with each other. He and his friends then watched as Ash caught Krokorok.
Mick found Pikachu while walking down the street and mistook it for the pre-evolved form of Zekrom. He then befriended the Pokémon, and when they found Ash, he let Mick borrow Pikachu in his battles. Pikachu then took part in a double battle with Krokorok as his partner and won.
