Bruce Banner was born in the town Dayton, in the state of Ohio, USA.
Bruce Banner is a genius in nuclear physics, possessing a mind so brilliant that it cannot be measured by any known intelligence test.
He did 2 years of medicine school before dropping out as his interest in nuclear physics grew.
He is a graduate of Desert State University in Navapo, New Mexico.
His college roommate was Peter Corbeau.
He got his diploma in Nuclear Physics, California Institute of Technology (Caltech)
Bruce Banner is of French descent. He had an ancestor who fought for France in World War I.
Bruce Banner is a lapsed catholic.
The name of his mother was Rebecca. Her family name was never mentionned, but as she was married to Brian Banner, she was known as Rebecca Banner.
In most recents issues, Banner carries around what he calls the “Bannertech”: A mobile operating system that can hack into most complicated systems, a shield that can protect him or extend to cover several people from most physical harm or increase his own strength, a pocket teleporter device in his satchel that connect to his lab, a host of scanners and a spy bot and finally a survival kit.
The kit included a needle and thread, a pack of waterproof matches, and a debit card.
Banner also carries around a old-powered teaser gun. It’s so strong its effects are measured on the Richter Scale.
While anger is well known to fuel the Hulk’s power, he also grows stronger the more radiation and the more dark magic he catalyzes.
Despite his high resistance to physical harm, it is possible to cause the Hulk injury.
However, he is capable of regenerating damaged or destroyed areas of his body including limbs, all of it’s skin and muscular mass, internal organs, and even his head.
The Hulk does not age. It is implied that the Hulk’s body effectively lasts forever.
The Hulk’s healing factor also enables him to revert any physical transmutation.
The Hulk is capable to adapt to inhospitable environments whenever it is necessary; places like the ocean floor or space.
He is able to breathe underwater due to his body developing a gland which creates an oxygenated perfluorocarbon emulsion which fills his lungs and equalizes the pressure.
He is therefore able to breathe fluid and avoid decompression and nitrogen narcosis.
After the Hulk adapts to a hostile environment (like space) he no longer needs sustenance and does not need air, water, food, or sleep.
The Hulk has demonstrated great psychic resistance as side-effect of his rage and the multiple personalities inside his mind.
The Hulk is immune to all known Earth-based diseases and viruses, including AIDS.
The Hulk has the unique ability of being able to see “astral forms“—or ghosts.
The Hulk also has a seemingly mystical homing ability that enables him to locate the area in New Mexico where he first became the Hulk.
This applies even if the Hulk is in another dimension.
Not usually a power associated with the Hulk, but there is enough evidence that Hulk possesses at least a limited ability to manipulate forms of energy, particularly gamma radiation.
