Once, Wilder was just a typical juvenile delinquent pretty-boy who expressed his discontent with the world by founding a motorcycle gang with some of his friends. Then one day, while they were having the sort of anti-authority fun The Man didn't like them having, they got beaten up by a rival gang. Having had the one thing he gave anything in the way of a flying fig about taken away, Wilder decided that the best thing to do would be to take his frustration out on society by joining up with the Destrons (Decepticons). And to his "credit", Wilder didn't do it by half—he has flung himself so deeply into the evil world of the Destrons and embraced it so eagerly, that there may be no coming back.
As a Headmaster Junior warrior, Wilder is bonded to a Transtector from the planet Master which takes the form of a winged, bipedal wolf-monster. In becoming a Destron, Wilder believes he has sold his soul, but based on the disinterested ease with which he is able to admit to this, he seems to consider it small change. And the hell with other people—Wilder is only out for Wilder, and the rest of the world can burn as long as he can claim to be powerful. As a Headmaster Junior, he is above humans, and he won't hesitate to beat his once-best friend half to death or kill a dog to prove it.
