Remlit

Mia is a beige cat belonging to Zelda and Gaepora that Link must help a birdrider find at the very beginning of the game.

She is harmless during the day, but during the night, she will turn dark and evil, patrolling Skyloft and fighting Link without hesitation.

Trivia

 * Link can throw Mia off the edge of Skyloft in either of her forms.
