The Destroyer

He has killed all gods. Even God himself can not kill him. He has the power to absorb the powers of others, and two loyal servants: Mr O (yes, that's how you spell it), and Omega. Mr O uses a powerful weapon that fires sonic waves. Omega uses a warhammer with the power to destroy any planet in a single strike. The Destroyer also had over a thousand different forms his arms can be, including his primary weapon: an extendable wrist blade. He also carries the GodSlayer, a qeapon so powerful it can kill gods. The Destroyer can only be hurt by mortal steel or what humans call iron.
