Demona (KH III: Reconnect)

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 revealed that she wanted to quit her alliance with the Horned King and start working with Maleficent's forces. Indeed, Ursula's renmant gave her the dark trident and a copy of Triton's crown so that she could obtain more power. She was ultimately slain by Macbeth, who sacrificed himself in the process.
