Midna in her true form. (As seen on deviantART.)
Midna is a canon character and secondary protagonist in the video game [The Legend of Zelda: Twilight Princess]. She is the titular Twilight Princess, a title given to her as the ruler of the Twilight Realm and of its inhabitants, the Twili. She is a Twili herself, and resembles a humanoid with unusual features and blue skin. Midna would be unable to survive in the World of Light (that is, the normal world) were it not for powerful magic; as it is, she can assume the form of a shadow at will, among numerous other abilities.
Clearly, Midna is not a Sue in the formal sense. She is neither unrealistically perfect nor charming, but she does have shades of good and shades of evil, as well as strengths and weaknesses clearly defined as such. Thus, she may be a well-rounded character; her Suethor certainly hopes to portray her as such.
Appearance and Abilities
Midna is a Twili, a race which branched off from humanity ages ago when they were banished to the Twilight Realm for attempting to steal the Power of the Goddesses and changed by the Twilight. However, she has two forms, as a result of events which took place in her backstory and during her canonical game appearance. Her normal form is that of a tall, svelte young woman of apparently 17. She has pale blue skin with strategically placed black patches on it and glowing aquamarine lines showing through her skin. Her long hair is a bright orange and is tied in front under her chin like the strings of a bonnet, and held in place at the top by a frame-like tiara of sorts that supports the jewel on her forehead. Her eyes have yellow sclera, the "white" of the eye, and red pupils, all of which hopefully goes with her made-up purple lips. She wears an elaborate cloak-like outfit of black-and-aquamarine fabric, embroidered with strange Twili designs and draped over body flowingly, down to her ankles, on which she wears anklets, and bare feet.
Midna in her cursed imp form. (Also seen on deviantART.)
In her Imp form, Midna can best be described as a "super deformed" version of herself. Her coloration is the same, though she doesn't wear her cloak, and her ears have become long and pointed like a cat's. She has a small fang which protrudes above her upper teeth. Her hair is tied back in a huge ponytail, complete with metal "scrunchie", which acts as a prehensile hand for her telekinesis. She moves everywhere by floating, and previously wore a helmet that was actually part of the powerful artifact called the "Fused Shadow". It was broken in the game, but she still retains some of its power.
