Ghostfreak

Ghostfreak (a.k.a. Zs'skayr) (voiced by Steven Blum) is one of the many villains from Ben 10. Ghostfreak was once one of the many forms Ben could turn into to fight evil. But Ghostfreak really had a mind of his own inside the Omnitrix. He finally managed to break free and tear off his second skin to reveal his true form. He planned to possess Ben in order to become whole again and control the world and universe. But Ghostfreak was defeated by the light.
