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: World-Breaker This is the Ultimate antagonist version of the Hulk. Banner's brain, driven by a seething rage and wreaking havoc. This version of the Hulk is angry at the world. Specifically the Super"Heroes" who have basically sought to eliminate him (at least he thinks so). He mourns the loss of his wife and people. He intends to take down the Illuminati, but he's still not a killer. "You wouldn't like me when I'm angry." this version of the Hulk fights like someone with a lot of experience and genius intellect to command his superhuman strength. This version has no problems hulking up. He's a cagy combatant and has a fondness for gladiator weapons. Run. This Hulk is angry. The World-Breaker is the hulk at his most massive, dressed in gladiator gear and with a really unpleasant look in his eye.

World-Breaker Hulk can access his rage with ease.
