Monkey Magic

An asteroid lands on earth with a baby monkey inside. His super hard head helps him become the leader of the monkeys. When they start overthrowing the humans because of him, the Gods send one of their warriors to keep the balance in check. The God crushes him so he decides to go on a journey to train and gain divine power. All the while an evil minion of a satan-esque character helps nurture the monkey's selfish and evil ways, hoping he will destroy the Gods for them. (Summary by War Machine)
