In their first demonic birth they become Hiranyaksha and Hiranyakashipu. Hiranyakashipu persecuted everyone for their religious beliefs including his son who was a Vishnu follower. he was protected by Brahma, and could by no means be killed. Vishnu descended as an anthropomorphic incarnation, with the body of a man and head and claws of a lion. He disemboweled Hiranyakashipu, and brought an end to the persecution of human beings including his devotee Prahlada
