Kubira

Kubira could change his body into the form of the one who is most feared/respected by his opponent. This ability also made it possible for him to copy the abilities of the person whom he has replicated. He was defeated by Akira even though Kubira replicated Kyo's true body. Kubira was the father of Antera. He made a deal with the Taishirou to cure Antera's illness. Her illness could not be cured, but it could be "slowed" by returning her body to the age before infection and stopping her aging. Under this deal, the Taishirou made Kubira go "berserk" which made him feel hungry for flesh when he saw someone, even his own daughter. He also had to separate himself from his daughter whose memory was altered to forget him. Kubira died because he violated his deal with the Taishirou.
