Zatanna
Catwoman discovers that Zatanna's mind-wipe of Dr. Light in "Identity Crisis" is not an isolated occurrence; Catwoman's journey from villain to hero and her resulting efforts to lead a moral life are retconned as being the result of Zatanna's mental intervention. Catwoman comes to distrust her memories, motives, and the choices she has made since that incident. In retaliation, Catwoman covers Zatanna's mouth with a piece of duct tape and shoves her out a window.
