Iron Man Vol 1 #084

He’s back! The most furious of all foes—the fearsome Freak! A city trembles in fear, and not even Iron Man can save it—not on the night of the walking bomb!

Iron Man arrives at the hospital with his enervator machine and meets Dr. Ritter, the surgeon who is going to operate on Happy Hogan who appears to have sustained heavy internal injuries while impersonating Iron two issues back. The operation goes well, and Tony Stark even assures Pepper there is no risk for Happy to turn into the Freak this time, since he has modified his machine. Yet, when the nurses are wheeling him back to his room, he turns into the Freak and disappears somewhere in the hospital. Shellhead finally finds him in the cobalt storage room, the same radiation the enervator uses ! The Freak is stronger than ever and even has his own kind of repulsor ray, he throws Iron Man through the wall into the sewers of the hospital. Dr Ritter orders to open the valve of the tunnel, to drown the Freak before the radiations make him explode. Instead, both Iron Man and the Freak find themselves in the East River and continues to fight, but Iron Man’s armour is damaged, and the Freak does not seem to tire out. But Shellhead is eventually beaten, lying still on the road, and the Freak, first unsure of what to do now that his only objective, the destruction of Iron Man, has been achieved, hops on a train headed toward Manhattan.
