What if The Marvel Cinematic Universe was owned by Universal Pictures/HULK

Plot

During the 1960s, scientist David Banner has the idea to forge supersoldiers by introducing modified DNA sequences extracted from various animals to strengthen the human cellular response, but General Thaddeus Ross denies him permission to use human subjects. Banner subsequently conducts the experiments on himself. After the birth of his son Bruce, he finds that his son may have inherited the effects and seeks a cure, but he is stopped in the process by Ross, who had found out about the secret work. Following a traumatic event, Bruce remembers nothing of the incident, and has been raised by the Krenzlers.

Years later, Bruce is a geneticist working with colleague and girlfriend Betty Ross, within the Berkeley Biotechnology Institute on nanomed research to achieve instantaneous cell repair by using low-level gamma radiation exposure to turn on the nanomeds once they are introduced into a living organism, planning to use it to cure all from sicknesses such as cancer and Alzheimer's. They get harassed by Major Glenn Talbot who plans to use the research to forge supersoldiers. During routine maintenance of their appropriated gamma-ray spectrometer, a circuit shorts and triggers the experiment's program sequence. Unable to prevent the machine from firing, Bruce throws himself in front of a colleague named Harper to shield the man and is exposed to a massive amount of gamma radiation.

Betty visits Bruce in the hospital and remarks that he should be dead, but Bruce feels great. A new janitor at the lab claims that he is Bruce's biological father, whom Bruce forgot. Bruce presumes the janitor was lying until he finds it was truth when he checks his own genes. When under extreme stress, Bruce transforms into the Hulk, a huge, humanoid, green-skinned monstrous being who destroys the laboratory, though Bruce forgets soon after. General Ross suspects Bruce of collaborating with David Banner. While Betty meets with David, General Ross interrogates Bruce but deduces he has repressed memories after questioning and orders Bruce to be put under house arrest.

Through a phone call with his father, Bruce learns that the radiation unleashed something that was already in his DNA, and that David Banner plans to have Betty killed by his dogs, which now have similar powers to the Hulk thanks to David mutating them with gamma radiation. Bruce is then attacked by Talbot, who accuses him of going to General Ross behind his back to cut him from the nanomed research, leading to a second transformation into the Hulk. The Hulk seriously injures Talbot before going to save Betty. After being wounded in a lengthy struggle, he kills David's dogs and changes back into Bruce before being captured by the military the next morning.

Bruce is kept under observation at a secret desert base, while Talbot intends to weaponize the Hulk's powers. Talbot subdues Bruce and places him in an isolation tank to trigger a transformation. David tries to recreate Bruce's failed experiment, but instead of turning into another Hulk he finds himself able to absorb any material he touches or energy to which he is exposed. He hands himself over to the military after lying to Betty and telling that he had accidentally killed his wife, Edith, in front of the child Bruce due to fury caused by Ross' interference.

Bruce awakens from a nightmare about the event, realizing his father thought he was a monster and tried to kill him while his mother protected him, and then turning into the Hulk. While attempting to gain a sample of the Hulk, Talbot is killed by a grenade launcher he uses. The Hulk escapes Desert Base and rampages across the desert to San Francisco, battling Army forces sent after him until Betty calms the Hulk into his human form.

David tries to taunt his son into transforming into the Hulk again but fails. He then decides to "go first" and bites an electrical cable, absorbing all the electricity in San Francisco. The electricity hits Bruce, triggering his own transformation. A brutal fight ensues between David and the Hulk which are firstly transferred into the sky and later into Pear Lake. David begins to absorb Hulk’s energy, but when the Hulk forces David to absorb his full power, it is too much and overwhelms him. As he transforms into a gigantic sphere of water, he is killed by a missile from the army.

One year later, Bruce is presumed dead, while General Ross mentions apparent Hulk sightings and Betty admits her love for Bruce. In a South American jungle, Bruce has become a doctor and is approached by rebel militants who want to take medical supplies from the poor. Bruce faces the militants' leader, warning him that, "You wouldn't like me when I'm angry". His eyes turn green and the Hulk's roar is heard in the distance.
