A beautiful, buxom young woman from a remote village in the mountains of China, Shampoo has grown up with a rather direct and uncomplicated personality. Even when Shampoo is being sneaky, she tends to do it in the most direct way she can. Shampoo is very proud of her strength, her beauty and her reputation for both.
Shampoo first met the (then female) Ranma shortly after she won her tribe’s annual martial arts tournament for women. When Ranma was caught eating her grand prize, Shampoo confronted him and Ranma challenged her. Shampoo lost, and chose to evoke ancient laws of her village that then pledged her to hunting down and killing Ranma, no matter what. Those same laws would have required Shampoo to marry Ranma if she had known he was a boy at the time. Shampoo has no knowledge of the effects of the magical springs of Jyusenkyou, and pursues her quest with a sort of sinister cheerfulness.
She is the strongest young woman of her tribe, which is an accomplishment in a tribe that reveres female fighters. She is, however, noteably less powerful then Ranma Saotome, as he beat her handly with a single shot in their first confrontation. Shampoo is definitely superhuman, with the ability to leap great distances, smash open walls and take brutal hits from other fighters as well.
