Overworlds: DiegoWT
Former street fighter.
Trained in various countries around the world and prided himself on being the best trainer in the world, but after losing to Alder, he asked to become his apprentice in order to train again.
In the anything-goes street fights, he has always believed in fighting fair and square.
He respects his master as a trainer, but he has a stubborn and inflexible side, such as not accepting his master's responsibilities as a champion and his absence from the Pokémon League.
