Dodge Grabbit was a potential Bone Trainer from The City of Brass. He attempted to get into the Coliseum there, but was stopped by Fuckin Gary. He would have beat him, had it not been for the fact that his best card, a Dracolich, was stolen by The Ballista Twins.
He told Skud Derringer all about the rules of the game, and requested the Genasi get his Dracolich back. In return, he promised to give Skud 6 blank Bone cards, to use in capturing creatures of his own. Skud agreed.
