Maleficent gets her wings cut off because Stephan/her childhood love wanted to become king
Maleficent saves Diaval and turns him to a man right before he was captured, to be "her wings"
Stephan and his queen have a daughter named Aurora which Maleficent then curses.
Aurora gets drawn to the dungeon by the curse of Maleficent. She pricks her finger on the spinning wheel and falls into a deep sleep. The kingdom declares war on Maleficent, but the fairies put the kingdom to sleep while they come up with a plan.
Maleficent kidnaps Prince Phillip with the intent of saving Aurora from her spell.
Maleficent’s wings are reattached. She then battles Stefan on a tower where he falls off to his death in the attempt to kill her. Soon after, Aurora was crowned queen of the human and fairy realms by Maleficent, forever unifying the two kingdoms, with Phillip by her side
