Demona
One of the few survivors of the destruction of Castle Moray, Demona is an immortal gargoyle sorceress who desires to destroy humankind for their part in killing off her clan years ago, without ever realizing that it was her betrayal that caused their demise in the first place. Demona has currently teamed up with Master Xehanort in order to bring her human elimination quest into the entire universe. She personally commands the Gargoyle type heartless. During her battle with Sora, Demona was slain by Macbeth, who sacrificed himself in the process, as per the curse that bound them both to eternal life.
