Biography
As the Seeker of Darkness, Slade is the supreme leader of the Heartless and is the most powerful and intelligent of his kind. He has full control over the darkness and can use it to its full potential. This allows him to, among other things, create powerful bursts of dark energy, enhance his physical prowess, navigate the worlds via Corridors of Darkness, steal the hearts of other worlds and their inhabitants, and possess other beings if they submit themselves to his power. In addition, he wields a dual-bladed staff reminiscent of Kevin's Dark Biker.Due to him having intentionally separated his heart from his body and soul before he gave into the darkness, Slade retained his self-hood, intelligence, and his human appearance after his transformation into a Heartless. Because he could think out his plans and pass for a human, he was able to destroy nearly every world in the Kingdom Hearts universe without revealing his identity up until he confronts the Eds at the Final Keyhole in Hollow Bastion.
