Maleficent
Maleficent was a malevolent and powerful sorceress. She wreaked havoc on a royal family for the simple reason that they did not invite her to the celebration of the birth of their daughter. Maleficent cursed the child and led their castle into ruin, until a brave hero defeated her using magical weapons.
Kingdom Hearts
Maleficent seemed to take control of the Heartless and conquered the world of Hallow Bastion (home of warriors like Cloud Strife, Squall Lionheart, Cid, the megalomanical Sephiroth and many more) and gathered together a group of other villains (Jafar, Hades, Ursula, Captain Hook, Oogey Boogey) from various worlds to conquer reality. She was defeated at Hollow Bastion by Sora, Donald Duck and Goofy, and it was later found out that she herself was a pawn of the evil Ansem.
