As the older, confident, sober brother of
Tony Stark, Gregory Stark was asked to participate in the
Ultimates program, aiding the team by providing whatever hardware they may need. He responded by giving them War Machine, the Red Wasp and Nerd Hulk. Brutally honest and completely immoral, Gregory gets along famously with Ultimates commander,
Nick Fury. After their bout with the
Red Skull, Gregory revealed to Fury that he knew Fury was the one who lured the Red Skull out of retirement by tempting the maniac with the
Cosmic Cube. Fury told Gregory that he was going to get his old job back no matter what it takes.
