Milestone: Hires Happy Hogan
Anthony Stark is a millionaire scientist and sportsman who runs a plant, a racing team, and one very well-kept secret: Iron Man. When a wind tunnel test slips its leash and threatens to tear the lab apart, Iron Man meets the runaway machine head on and beats it at its own game, becoming a human fan and blowing the whole storm back down to scrap. He has barely cooled the turbines when the vault alarm sounds. The thief is Gregor Shapanka, his most trusted scientist, grabbing for the secret formulas he swears will buy him eternal life. Iron Man collars him, and then Stark, feeling generous, lets the man walk, a mercy that ages about as well as milk in the sun.
The armor is more than a weapon. Its chest unit is the battery keeping Stark's damaged heart beating, and when he forgets to recharge it mid-race, the Stark Special skids into an embankment and nearly finishes the job for him. A stranger named Happy Hogan hauls him out of the flames, asks for nothing, and lands himself a job for the trouble. Shapanka, meanwhile, has taken that earlier mercy as a dare. He builds a freezing suit, empties a bank, and slides across town as the media-crowned Jack Frost to put Stark on ice for good. When ice arms drag Iron Man into a slow freeze, the hero remembers the flashlight built into his own suit, and one small adjustment turns its beam into a heat ray that melts the self-styled Walking Deep Freeze into surrender. Stark ends the day with a new right hand in Happy Hogan and not the faintest idea how close he came to leaving it as a Stark-shaped icicle.
