A mysterious masked being. Midna was a princess in the Twilight Realm who was transformed into an imp by Zant. Midna's personality is characterized by a sharp tongue and a tendency to act on whims. Midna pairs with Link to save the world. She also possesses powerful magic skills, such as the ability to warp through space.

In Super Smash Bros. Wii U/3DS
Midna appears as a Assist Trophy, she will grab at any enemy fighters nearby and tosses them into the air. Like grabs by fighters, Midna's grab cannot be shielded against. Also, if there are no enemies close to her, she'll chase some down by teleporting.
Midna is a descendant of the Twili and comes from the Twilight Realm. She doesn't mind getting a bit bossy with Link, and though she offers to help him, her motives are unclear. Try to ignore her dismissive attitude--maybe she just has trouble showing her true self.
