Mazura

Horsehead (マズラ, Mazura) is the first boss Link encounters in Zelda II: The Adventure of Link. Link can be knocked back significantly harder when struck by Horsehead's club, compared to length Link is knocked back by other enemies. He is defeated by striking his head, his only vulnerable point, multiple times. Horsehead is found in Parapa Palace and wields a powerful club.

Trivia
In the Japanese version of the game, Horsehead roars.
