From: http://www.comicvine.com/hulk/29-2267/ Dr. Robert Bruce Banner was born to Dr. Brian Banner and his wife Rebecca. Rebecca loved Bruce very much, but her drunken husband Brian was jealous of the attention she gave to their son. Brian also thought that Bruce wasn't human due to genetic modifications Brian had made to himself. One day Brian killed his wife and was placed in a mental institution. Bruce would grow up hiding all his pain and live with his aunt Mrs. Drake. Dr. Robert Bruce Banner grew up to be a brilliant scientist and started working for the U.S. Department of Defense, in charge of an experimental Gamma Bomb. A teenager named Rick Jones took a dare from some friends to drive inside of an off-limits Military-run atomic testing range seconds before a powerful Gamma-ray Bomb was due to be detonated. The scientist/physicist Bruce Banner had selflessly endangered himself to save the life of a boy whom had wandered onto the grounds of a secret military bomb testing range just moments before the detonation of the top secret Gamma Bomb. Banner told his colleague, Igor Starsky (real name Igor Drenkov) to hold the test, but Igor was a Soviet agent and did no such thing. Hoping for Banner's death, and the end of his project, Igor allowed the test to continue. Dr. Banner then dashed to the teenager and sped with him towards a nearby trench. Frantically, Dr. Banner hurled Rick Jones into the crevice where the teenager was shielded from the mysterious, menacing Gamma Rays. But, at that very second, standing in the open, exposed and un-sheltered, the heroic Bruce Banner absorbed the full impact of the gamma explosion, even though the center of the blast was a good five miles away. His ear-piercing screams filled the desert air, as the scientist lost all sense of time and space. As a strange, awesome change took place in the atomic structure of his body. A short time later, Dr. Banner regained consciousness at the base hospital, with Rick Jones standing by his side. Rick Jones swore never to leave Dr. Banner again. During the rescue, Banner's body was irradiated by the gamma blast which, when combined with his own unique genetics, led to the birth of the Incredible Hulk. As the sun set, the Geiger counter on a nearby table began to tick louder and louder until Bruce Banner had turned into the most dangerous living creature on earth. Version: Joe Fixit This is the "Gray" Hulk, the Joe Fixit version is the smallest and weakest (to begin with anyway) but he is smart, cunning, and capable incombat Joe is a unique persona, like the Savage Hulk. You could say he personifies Banner's selfishness. Joe Fixit is morally ambiguous, cantankerous, greedy, horny, lazy, hedonistic, and rough edged. He could be said to be Banner's wish fullfillment run amok. He's been shown on occasion to have a (tightly reigned in) conscience. He detests most of the other personailities. "This is not gonna be pretty." Joe Fixit is a weaker version of the hulk who compensates by being a superior fighter. Like the merged version, he has difficulty accessing the rage-induced strength. In addition he seems to have a much lower limit. A leg-breaker in Vegas. This version of the hulk is a great antagonist for lower powered heroes, he's capable of doing the right thing but he's just as capable of being an obstinate jerk who messes up anyone who gets in his way. Joe Fixit is a massive man with slate gray skin and black hair. He dresses in tailored suits when he can.

Fixit can only access his Adrenaline via strength of will or his sheer rage. If he's enraged he can access it at will, otherwise he requires an EGO roll each use.
