Origin
Maleficent's Raven first appeared as a minor character going by the name of Diablo (the Spanish word for "devil") in Sleeping Beauty. Throughout the movie, Diablo essentially serves as Maleficent's eyes and ears, finding Aurora in the forest and 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 climax, the raven alerts Maleficent's goons of Prince Phillip's escape from the dungeon with help from the three good fairies, and when the protagonists are able to get past the castle boundaries, Diablo attempts to alert the sleeping Maleficent. Merryweather spots the raven and gives chase, eventually turning the bird to stone. This is a short-lived victory, however, as Diablo was able to succeed in awakening Maleficent, setting the scene for the evil fairy's final confrontation with Prince Phillip.
