Powerhouse of the Magnetic Men, I often mix him up for being another Sabretooth amalgamation. But, the concensus is Marvel's Unus and DC's Iron. Which, yeah, that makes sense to me. Unus was an early Brotherhood member while Sabretooth came around ages later. He also gets a little bit of Steel in his human form when he's a construction worker named John Henry Steele.

Upper torso, arms, upper legs, and head were all Hyperion. Lower torso was Wonder Man. Boots were Hercules. Full sanded down and resculpted the head. Sculpted the belt, knees, boots, and torso strap. Full repaint, and all done!
