Fictional character biography.
Brian regarded his father as a monster and believed that he had inherited a "monster gene" from him, and so promised himself that he would never have any children, for fear of bringing another Banner into the world.
As an adult, Brian married a woman named Rebecca, earned his PhD in physics and found a job in Los Alamos, New Mexico working for the United States government on a project developing a clean way to create nuclear energy. The stress of his job eventually lead Brian to become an alcoholic, and he frequently lashed out at those around him. While drunk at work one day, Brian accidentally overloaded some machinery, causing an explosion that cost him his job. Despite his vow never to have children, Brian impregnated Rebecca, who gave birth to their only child, Robert Bruce Banner. Brian believed Bruce had inherited both the "monster gene" and genetic defects due to the accident in Los Alamos, so he ignored him completely and attempted to keep Rebecca away from him. He frequently left Bruce in the care of the neglectful Nurse Meachum. When Bruce woke up one Christmas morning and opened a present from his mother, a complex model, he assembled it easily, despite his young age. This convinced Brian that his assumptions about Bruce were correct. He beat Bruce and, after she came to her son's aid, Rebecca as well. After enduring several years of abuse from Brian, Rebecca attempted to escape from him with Bruce. Brian discovered his wife and son packing the car just before their escape, and he smashed Rebecca's head against the pavement, killing her in front of their young son. Brian managed to stop Bruce from testifying against him at his trial for Rebecca's murder, saying that if he did so, he would go to Hell. Terrified, Bruce perjured himself, testifying that his father never abused him or Rebecca, and that his mother tried to run away for no reason. Brian escaped conviction due to lack of evidence, but is later arrested when he drunkenly boasted about beating the law by bullying his son. Brian is imprisoned and later placed in a mental institution. Bruce, meanwhile, is left in the care of his Aunt Susan, now known as Mrs. Drake.
After 15 years of confinement, Brian, who is believed fit for reintroduction into society, is released into a reluctant Bruce's care. Living with Bruce caused Brian's delusions to begin again and, on the anniversary of Rebecca's death, Brian and Bruce engaged in a verbal and later physical fight at Rebecca's grave on a stormy night. During the fight, Bruce accidentally killed Brian by knocking him headfirst into Rebecca's headstone. Bruce repressed the memories of Brian's stay with him and his subsequent death, making himself believe that, as the two of them fought at Rebecca's grave, Brian had simply beat him and left, later being killed by muggers.
Brian's ghost would continue to haunt Bruce's alter-ego the Hulk after his death, often appearing to taunt him, stating that Bruce was no better than he himself; villains such as Mentallo, the Red Skull, Devil Hulk, and Guilt Hulk would also use the image of Brian Banner against the Hulk in an attempt to weaken him. One prominent storyline saw the Red Skull use mind-manipulating technology to make the Hulk see the Juggernaut as his father and use the Hulk to attack other heroes, but this plan failed when the Juggernaut praised the Hulk's efforts, something that the true Brian had never done.
When Bruce Banner and the Hulk were fused back together after the events of "Heroes Return", Bruce found himself in Hell, where he met several former adversaries, including his father, Brian. Bruce was terrorized by Brian, Leader, and Maestro. He eventually stood up to his father, attacking and strangling him before being returned to Earth by an image of his wife, Betty Ross. Having faced his father, Bruce's haunting by him ceases.
When Bruce began to suffer from Lou Gehrig's disease, Mister Fantastic, in order to cure him (based on a cure created by the Leader), had Brian Banner's corpse exhumed, so as to collect some of his DNA. With the resulting samples, Mr. Fantastic managed to cure the Hulk, instructing Ant-Man in shrinking down to a point where he can insert Brian's gene samples into Banner's own DNA, with the energy surge released when the Hulk returned to human form infusing the healthy DNA with his own system. Bruce subsequently visited his father's grave and laments his confusion over his feelings for his father, noting the fact that he now owed his life to the man despite his old issues with him.
In "", the hero Trauma, who has the power to change into an opponent's worst fear, adopted the guise of Brian Banner to use against the Hulk during the "World War Hulk".
Recently, Bruce has implied that killing his father wasn't actually an accident, noting during a confrontation with Daken and Wolverine that he has managed to avoid causing any innocent deaths when he is rampaging as the Hulk—save for those occasions when he is under the control or influence of something else—and suggesting that it is unlikely that he would make such a 'mistake' in his more limited human form. In an indirect manner, Brian's memory also resulted in Bruce stopping his fight with his son Skaar after the Hulk was restored following the final battle with the Intelligencia, Bruce recognized that he couldn't continue the fight with Skaar- regardless of how much either side might 'deserve' to die- without becoming his father all over again.
During the "Chaos War" storyline, Brian Banner returned from the dead and ended up facing the Hulk again alongside the Abomination after what happened to the death realms. Brian transformed into a creature resembling a mix of the Guilt and Devil Hulks as he does. When Brian tried to kill Rebecca again, the Hulk ended up fighting him alongside Skaar. Brian fed on the Hulk's anger towards him, becoming stronger. It is only when the Hulk's lost love Jarella tells him to remember his love for her that the tide turns. The Hulk instead focused on the positive emotions inspired by the rest of his allies and finally defeated Brian Banner.
Brian Banner returned to the living as a ghost who possesses Sasquatch and puts him on a rampage. This rampage attracts Hulk. After figuring out that his dad is behind the possession and learning the reason why Riot Squad member Jailbait lost control of her powers, Hulk put an end to Brian's plot by draining the gamma energy out of Sasquatch enough to regress him back to Walter Langkowski. This was done at the cost of apparently trapping Brian Banner in the Hulk's body. It was revealed that Brian Banner's ghost was being instructed by a being called the One Below All when Absorbing Man in his Red Dog alias absorbed some of Hulk's gamma energy.
While in the Below-Place while studying the Green Door, Leader encounters Brian Banner who wants Leader to help him escape the Below-Place. Instead, Leader removes Brian Banner's skeleton for research.

Other versions.
In the alternate timeline of the 2005 "House of M" storyline, Brian D. Banner believes Bruce to be a mutant created through the radiation he experimented with and attempts to kill him. He murders Rebecca when she gets in his way. Before he can harm the young Bruce, Brian is shot to death by the police who arrive at the scene. This is very similar to the scenario involving in the Hulk film (see below).
