Launch is a Yandere to Tien Shinhan from the anime Dragon Ball.
She 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 sweet, blue haired woman, who is pure-hearted and kind towards others.
Her other personality is an angry, trigger-happy, blonde haired woman, who 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. The only side of her that makes Tien fall for her is her bad side.
Her blood type is AB.
