Hulk

David Banner is a genetics researcher who experiments on himself, trying to improve human DNA. Once his wife gives birth to their son Bruce, David realizes his mutant DNA has been passed on and attempts to find a cure for his son's condition. The government, represented by Thaddeus "Thunderbolt" Ross, shuts down his research after learning of his dangerous experiments. David, in a fit of rage, causes a massive explosion of the facilities' gamma reactor, and accidentally kills his wife. He is then put into a mental hospital, while 4-year-old Bruce is sent into foster care and adopted, taking on the last name of Krenzler, believing his biological parents are deceased. The events leave Bruce unable to conjure the memories into reality. Years later, Bruce is a brilliant researcher freshly graduated at the University of California, Berkeley. The military-industrial complex, represented by the unscrupulous Major Talbot, becomes interested in the research to build regenerating soldiers. David reappears and begins infiltrating Bruce's life, working as a janitor in the lab building. Ross, now an Army general, also begins to investigate. Ross, the estranged father of Bruce's ex-girlfriend and co-researcher Betty Ross, becomes concerned both for his daughter's safety around Bruce, but also because Bruce is working in the same field as the father he does not remember. Bruce succumbs to a scientific experiment accident. Afterwards, we see Bruce sitting in a hospital bed telling Betty that he's never felt better, which she can't fathom due to the fact that the nanomeds have killed everything else they've touched. The radiation has intertwined with Bruce's already-altered DNA. That night, his father confronts him, revealing their relationship and hinting at the mutation inside Bruce. Using Bruce's DNA, he begins experimentation on animals. Soon after, the building rage within him stemming from all of the stresses building up around him activates his gamma-radiated DNA, transforming Bruce into the Hulk. After the destruction at the lab, Bruce is found unconscious and at home by Betty. Bruce barely remembers his transformation, a sensation similar to birth. Ross arrives, suspicious, and places him under house arrest as well as taking over Bruce and Betty's lab. That night, David phones Bruce and tells him he has unleashed three mutant dogs to Betty's house. Enraged and attacked by Talbot, Bruce transforms again and, after seriously injuring Talbot and his henchmen, fights and kills all three dogs and saves Betty. The next morning, Bruce is tranquilized and taken to an enormous underground base in the desert. Betty tries to convince her father to allow her to attempt to help Bruce control his transformations, but Ross remains extremely skeptical, believing Bruce is "damned" to follow in his father's footsteps. In the meantime, David breaks into the lab and subjects himself to the nanomeds and the gammasphere, gaining the ability to meld with and absorb the properties of anything he can touch. Talbot, seeing an opportunity to profit from the Hulk's strength and regenerative capability, attacks and taunts Bruce, but fails. Talbot puts him in a sensory deprivation tank and induces a nightmare that triggers his repressed memories and transforms him into the Hulk, eventually leading to the death of Talbot. David confronts Betty and offers to turn himself in. In exchange, he asks to speak to Bruce "one last time." The Hulk escapes the base in the process. He battles the army in the desert, defeating four tanks and two Comanche Helicopters, and leaps all the way to San Francisco to find Betty again. Betty contacts her father and convinces him to take her to meet the Hulk, believing that he needs "a chance to calm down." Bruce's love for her comes through the Hulk, and he transforms back into his human form. David is allowed to visit the base and talk to Bruce. David, having descended into megalomania, fails to convince Bruce to give him his power. David transforms into a powerful electrical being after biting into a wire and absorbing the energy. Bruce then transforms into the Hulk and battles his father. Both are presumed dead after Ross orders a Gamma Charge Bomb to end the fight, leaving no trace of either men. A year later there have still been numerous sightings of the Hulk. Bruce finds exile in the Amazon Rainforest as a doctor in a medical camp.
