"What If Rick Jones Had Become the Hulk?"
Well, for starters; ol' Greenskin's propensity for purple slacks would take a back seat to battered blue jeans and Rick's music career as the next Bob Dylan would never get off the ground.
It all starts/diverges on a desert testing range when Rick Jones, not Bruce Banner experiences the full force of Gamma radiation rewriting his genetic codes.
Night falls and the youth succumbs to his first fear-fraught transformation into 1,000 pounds of misunderstood muscle. A passing army patrol witness the destructive power of the brute and dub him, "the Hulk".
Cool name! Still a teenager at heart, Rick adopts the sobriquet. Banner manages to calm the beast and contain him in a subterranean chamber. As Bruce works hard on an invention to cure Rick's rage, events in Asgard conspire to bring around the formation of the Avengers.
