Umio

This trainer navigated a perilous journey with Ash, Neesha, and Corey, successfully surviving Mewtwo's storm to reach New Island. He voiced opposition to Mewtwo's invitation, arguing that Pokémon cannot be trainers. Despite attempting to battle Mewtwo with his Gyarados, the psychic Pokémon proved superior. Ultimately, all of his Pokémon were duplicated by Mewtwo during this event.
