Maleficent

The Forbidden mountain.

Revenge, causing chaos, her raven, power, dark magic, taunting her enemies, curses.

Being uninvited or excluded. The good fairies (Flora, Fauna, and Merryweather), her minions' incompetence, failure, Aurora.

Dark magic, and shapeshifting.

Diablo (Raven)

She carries a staff with a glowing green orb at the tip through which she casts her spells.

Maleficent is a tall, slender, pale green-skinned woman with a narrow face and a prominent chin. She is also darkly beautiful and icily elegant. Her tall demeanor is such that she dwarfs most people. She also has yellow eyes and black horns.

She is clad in a black-and-purple robe with bat wing-like edges; underneath her robe, she wears a dress with the same color pallet but with some red instead of purple and wears a gold ring with a large mysterious circular black stone in it.

One of her most powerful abilities is to transform herself into a massive, black, fire breathing dragon. (She will only use the form as a last resort.)
