Titanium Man

Titanium Man (Boris Bullski) is an agent working for A.I.M.

Biography
His suit (presumably based on the designs of the original Iron Man armor that were supplied to A.I.M. by Obadiah Stane) has a limited onboard battery charged by high intensity radiation. He is first seen at the nuclear power plant, working alongside mercenaries to obtain a power source for A.I.M., when Iron Man arrives and stops him. Later however, Titanium Man and A.I.M. soldiers later launch an attack on the Stark Industries compound to try to take Stark's Iron Man suit, but Iron Man defeats him and all of his A.I.M. forces.
