New Teen Titans #13 November, 1981.

Wonder Girl returns home briefly to see Terry Long, while Starfire competes in an Amazon tournament on Paradise Island. Changeling is healed of his wounds by the Purple Healing Ray, only to have it drive him temporarily insane, causing him to take the form of a brachiosaurus and to attack the Amazons. Raven's soul-self overcomes him and returns him to normal.
