Which avtar did Vishnu take to kill hiranayakasipu?

Vishnu took the avatar of Narasimha to kill Hiranyakashipu. Narasimha is depicted as a half-man, half-lion form, which allowed him to bypass the boon that made Hiranyakashipu invulnerable to being killed by man or beast. In this fierce form, Vishnu defeated the demon king at dusk, placing him on his lap and slaying him with his claws. This avatar illustrates the theme of divine intervention to protect devotees and restore cosmic order.
