Throughout the movie, the raven would do all of Maleficent's dirty work, such as finding Aurora in the forest or keeping Prince Phillip from escaping the Forbidden Mountain. Diablo would stick to Maleficent's side as a loyal pet whenever he wasn't causing trouble for the heroes, but later met his demise when the three fairies turned him to stone and ultimately, a gargoyle on Maleficent's castle.
