Zant Mask

Zant Masks are giant flying replicas of Zant's mask in the Palace of Twilight in The Legend of Zelda: Twilight Princess. Link can defeat them by either simply attacking them with his sword, or stunning them by deflecting their power back at them. They can teleport, and will do so after they launch a Twilit Energy Ball.

The Light Sword can defeat Zant Masks with a single strike.
