(Poly) Good and Bad Launch. (Dragon Ball)

Launch (ランチ Ranchi, lit. "Lunch") is a woman with a strange disorder which causes her to switch between two different personalities each time she sneezes. Her first personality is a blue-haired woman, who is sweet, pure-hearted and cheerful and always ready to help. Her other personality is a blonde-haired woman, who is angry and trigger-happy and commits crimes for money and is quick to respond with gunfire when angered. Neither of Launch's personalities remembers the other's actions or anything they said, that is until the King Piccolo arc, which is evident when she remembers who Krillin was when he died.
