Origin
Maleficent's Raven first appeared as a minor character going by the name of Diablo in Sleeping Beauty. Throughout the movie, Diablo essentially serves as Maleficent's eyes and ears in the sky, such as finding Aurora in the forest or keeping Prince Phillip from escaping the Forbidden Mountain. Diablo sticks to Maleficent's side as a loyal pet and remains perched on her shoulder when not doing her bidding. In the film's final scenes, he alerts Maleficent's goons of Prince Phillip's escape from Maleficent's dungeon with help from the three fairies, and when Phillip and the fairies escape the castle boundaries, Diablo attempts to alert the sleeping Maleficent. Merryweather notices him and gives chase until she manages to turn him to stone just outside Maleficent's tower, although it is a pyrrhic victory, since Diablo ultimately does wake Maleficent up, setting the scene for the final confrontation.
