General: corruption

A character is turned evil (usually accompanied by a costume change), or is otherwise made to think and act more in line with the desires of the evil being* that corrupted him/her.

*The being controlling the corrupted character must be considered evil, whether it be a demon, a normal enemy of the character, a "bad guy" in the plot of the character's story, or something else like that.
