WM Wonder Man Most Powerful Avenger Colossus vs. Grey Gargoyle This guy used to beat the Avengers with Hulk on the team. Colossus however is living steel like Grey Gargoyle is living stone.
MET Metalmanx Illuminati Founder Well, since steel is far stronger than stone, I'm going with Colossus.And since we're talking organic unknown steel, then it's even stronger and easier to win with.
