Possessed/Brainwashed

Heroes who get possessed or brainwashed by the villain. Possession means that the host's body was taken over by a demon or some other form of evil spirit, and brainwashing simply means that they were hypnotized, mind controlled, bitten by rabid animal, etc. Alternatively, they can still be good and possessed or brainwashed at the same time, but they are mostly controlled by evil forces.
