Maleficent is a major antagonist in the Kingdom Hearts series. She is an evil sorceress who made her first appearance in Disney's Sleeping Beauty. She was first seen in Kingdom Hearts in Hollow Bastion. Unlike the other Disney villains (with the exception of Pete), she plays a large part in the overall story rather than just in the world she came from."You poor, simple fools! You think you can defeat me?! ME, the mistress of all evil!?"
