Dumbbellloid

Dumbbellloid (ダンベルロイド Danberuroido?): Dumbbellloid, designated A-01, is created when the Kitaeru (鍛える?, "to workout") Metavirus infects a dumbbell. A passionate trainer, Dumbbellloid uses his dumbbells to force people to exercise against their will or kill them if they can not keep up with his fitness program. He is eventually outmatched in strength by Blue Buster who singlehandedly destroys him.
