Angel is a white rabbit who is the pet of Fluttershy. Although he seems incapable of speech, Angel clearly understands the ponies, and will respond to their questions and comments with elaborate gestures and pantomimes to convey his meaning.
Angel is often portrayed as bratty and uncooperative towards Fluttershy and whoever else might be trying to care for him. This behavior is supported by the show's canon; in episode 7 of Season 1: Dragonshy, Angel first defies Fluttershy's repeated requests that he eat just a little more of his carrot, then throws the carrot at the back of her head.
