The Legend of Zelda: Twilight Princess - Midna 005

Midna is an imp like creature whose background and purpose are unknown throughout most of the game. She is a member of the Twili people who dwell within the Twilight Realm. She is first seen in the Faron Woods as Link is dragged away in wolf form. Midna then appears within Hyrule Castle and helps wolf Link escape. She acts as a companion for Link throughout his quest.

When Link is in the Twilight Realm, Midna will ride on top of wolf Link. While in wolf form, Link uses Midna to reach distant ledges and also uses Midnas charged attack to defeat multiple enemies at once. Midna is also used as a form of transportation. Wolf Link can speak with Midna and she will warp him to any place where there is a warp portal in the sky. When Link is in the world of light, Midna disappears into Links body. Early in the game, Midna takes Link on a quest to recover three fused shadows. Zant steals these three fused shadows.

Midna later tries gaining access to the Twilight Realm only to see that the Mirror of Twilight is broken. This puts Midna and Link on their next quest to find three mirror shards and enter the world of Twilight. Midnas character goes through quite an evolution throughout the game as her motives have changed because of the selflessness of both Link and Princess Zelda. At the end of the game, it is revealed that Midna is the Twilight Princess and her true form is revealed.
