Devadatta

One of Buddha's first disciples. The son of Bandaka, Devadatta had a difficult childhood. He met Tatta when looking for a warrior, and through Tatta, Devadatta met the Buddha. He leaves the sect when he is not chosen to be Buddha's successor and attempts to form his own sect by stealing Buddha's followers. When that fails Devadatta plots to kill Buddha; first by dropping a boulder on him, then by having an elephant stampede him. When his initial attempts fail, Devadatta poisons his nails but accidentally injures himself with them when he trips. In his final moments, he reveals that he hated the Buddha because he wanted to be just like him but couldn't. (Source: Wikipedia)
