Omfak

Omfak is a wolf-headed creature who apparently was "guarding the shrine" according to Impa. He could shoot lasers out of its eyes, and his head would turn into a lion that could spit fire, and also a giant pair of lips. He claims that "Whatever (he) sees, (he) will devour", as demonstrated while killing and eating a bird. When Zelda destroyed him, he exploded into a flock of crows, ravens, and blackbirds. He is this game's equivalent of Lupay from "Faces of Evil". He also bears some similarities to Glutko from the same game, mainly that both have the gluttonous habit of eating anything they see and both guard the shrine of the island containing the only weapon capable of defeating Ganon.

Strategy
Omfak will rotate between his three heads, however only his "Lips" head can be damaged. While in his Wolf head he'll shoot out star shaped lasers and while in his Lion head he'll shoot out fireballs. However as with every other boss in the game a single strike (this time from the sword) is enough to defeat him.
