MARVEL COMICS: Marvel Cinematic Universe bio Hulk

Marvel Cinematic Universe: Dr. Robert Bruce Banner is a renowned scientist in the fields of biochemistry, nuclear physics, and gamma radiation. However, after a Gamma Radiation experiment went awry, the mild-mannered scientist found himself plagued with a peculiar condition. When angered or provoked, he would transform into the rage fueled and nearly mindless, green-skinned monster known as the Hulk. Now, fearful of the damage that the Hulk could inflict, Dr. Banner chooses to live a discreet life in remote parts of the world, working to cure the sick and help the poor while trying to elude those who would take advantage of his ability to change into the enormous, green menace. When a mounting threat calls for Banner's specialized scientific expertise, S.H.I.E.L.D. Director Nick Fury recruits him, knowing full well that the incredible strength of Banner's alter ego, the Hulk, would be an additional asset to the Avengers. After the Avengers split up, he became good friends with Tony Stark and was also given the freedom to live in the world without being hunted down.

GAMMA ACCIDENT Bruce and Betty Ross are recruited by the US Army to work on a top-secret research project under the guise of researching radiation resistance called the Bio-Tech Force Enhancement Project. However, the project's true intention was to duplicate the results of Project Rebirth by making Super Soldiers using a combination of Bio-engineering and gamma radiation. The project was run under the watch of General Thaddeus Ross, who is the father of Bruce's then girlfriend, Betty.xxxEventually, Banner became so confident in his work that, in order to prove his work's worth, he decided to test it upon himself. However, the combination of what was really a replication of the Super Soldier Serum and high doses of Gamma Radiation (presumably an above lethal amount) caused Bruce to undergo a violent transformation. The affects of the procedure caused Bruce Banner to develop the alter ego, the Hulk, temporarily transforming him into a giant, green-skinned, muscle-bound titan with incredible strength, but who posed very little intelligence and was driven by fits of extreme rage, however, his transformations were temporary.xxxxAn enraged, nearly mindless Hulk destroys the lab, hospitalizing his lover Betty, and crushing General Ross' arm. Bruce tried to visit Betty while she was in the hospital, but her father made him leave and told him that when he leaves, the United States Armed Forces will come after him. Now a fugitive from the United States Army, and Betty's father, General Thaddeus Ross, Banner goes on the run.xxxxThree days after the accident, Ross meets Banner in a hospital, offering him to take him to a lab in Maryland. Banner refuses, though blames himself for all the people he hurt, including Betty Ross. Banner runs off, prompting Ross to order his troops to chase after him, only to find that Banner was gone.
