Hoppered is an odd person who is very misformed. His legs while attached to his body don't seem to be able to work, he also has a large hump on his back. As a member of the gung ho guns he wants to exact revenge on Vash the Stampede. His weapons include a large shell that he can use to smash into people, as well as multiple guns. Hoppered uses his hands as feet enabling him to move around.
Hoppered lived in the city of July, shrouded under a cloak and wheeling around on a cart for mobility. He kept a blind girl tied up in his apartment, and he apparently loved her. Unfortunately when Vash the Stampede destroyed July this girl was killed. Hoppered happened to be in the desert at the time, but so grief stricken at the loss of his love he sought revenge on Vash.
