Zant

Zant is unusual to the Twili race and is the self-proclaimed ruler of the Twilight which engulfs much of Hyrule during Twilight Princess. He is portrayed as the primary antagonist for the majority of the game and possesses powers beyond Link's comprehension. There are multiple ways of defeating Zant, the first suspected way being the use of the Fused Shadows. When Zant steals these away from Midna and returns her to the Light World, the only option left to reach and defeat Zant is to find the Mirror of Twilight which will grant access into the Twilight Realm.
