Agent Weaselman is a field agent that works for D.O.O.M. as well as being one of The Chameleon's disguises (it is unknown if there is a real Agent Weaselman or if this was The Chameleon for the entire time). He has only appeared in Share-A-Lair. In the episode, Agent Weaselman warned D.O.O.M. about T.U.F.F. trying to destroy them. Agent Weaselman speaks with a thick German accent and is voiced by Butch Hartman.
