Wolf Link

Wolf Link is the sacred blue-eyed beast in Twilight Princess. He is the "divine beast" that Midna stated her people had long believed would "free" them. Link becomes the wolf when he passes the barriers of the ever expanding twilight, or once he gets the shadow shard he can change at will. His whole body changes and reforms and leaving only his blue earring. Though losing the ability to use items, the new form grants Link heightened senses and speed, and the ability to dig, along with a jugular-biting attack. In this form Midna rides on his back, gives you directions, and uses the dark energy attack to help attack surrounding foes. Your attacks are generally the same though they are unwieldy. You can only warp as Wolf Link.
