Horsehead (マズラ, Mazura) is the first boss Link encounters in Zelda II: The Adventure of Link. He is defeated by striking his head, his only vulnerable point, multiple times. Horsehead is found in Parapa Palace and wields a powerful club.

Link will be knocked back significantly harder when struck by Horsehead's club, compared to length Link is knocked back by other enemies.
