Midna

Midna (Japanese: ミドナ, Hepburn: Midona) is one of the main protagonists in The Legend of Zelda: Twilight Princess, a 2006 video game in Nintendo's The Legend of Zelda series. She is a member of the Twili, a fictional race of magic-wielders, who joins forces with Link to prevent the kingdom of Hyrule from being enveloped by a corrupted parallel dimension known as the Twilight Realm. While Midna appears as an imp-like creature in the majority of Twilight Princess, her actual form is humanoid. She was designed by Yusuke Nakano and voiced by Akiko Kōmoto. Midna's first appearance was in a trailer for Twilight Princess shown at the 2005 Electronic Entertainment Expo (E3); at the time, her gender was unknown, leaving some journalists confused about it.

Midna was generally well received by critics and gamers alike. Her role in Twilight Princess has been compared to that of Navi, a character who accompanies Link in the 1998 game The Legend of Zelda: Ocarina of Time. Midna makes minor appearances in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS and Wii U, and returns as a playable character in Hyrule Warriors.
