Shampoo

Shampoo, another one of Ranma's fianceés, is a Chinese Amazon. She became Ranma's fianceé when Ranma-kun defeated her in combat, after Ranma-chan did. The Amazon law says that if a female outsider defeats an Amazon, then she must give her the Kiss Of Death, chase her to the ends of the earth, and kill her. This happened to Ranma-chan after she defeated Shampoo, however, the law has a second part. If an Amazon is defeated by a male outsider, than she must marry the outsider. Ranma-kun happened to accidently defeat her.

Shampoo has a Jusenkyo curse in which she becomes a cat when splashed with cold water.
