Hajime is an Ace Trainer, formerly a member of Team Rocket. He does not talk about the latter and would prefer to pretend it never happened. He mostly hangs around in places like Victory Road, looking for only the strongest of opponents to battle. He won't challenge just anyone to a fight, but if you're brave enough to challenge him to a fight, he won't hold back. He's thought about trying to become a Gym Leader or even the Champion, but he'd prefer to seek out his own opponents without having to worry about the sorts of responsibilities that go along with that sort of thing.

His team consists of Scizor, Volcarona, Scolipede, Armaldo, Accelgor, and Kricketune. Scizor is his favored Pokemon to battle with, and no one's really sure why he's got the Kricketune. (It's not very good at fighting.) The Kricketune is not very bright and prone to popping out of his Pokeball at random times, chirping at inopportune moments, getting into things, and generally making a nuisance of itself.
