Marvel Cinematic Universe Hulk
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.

THE INCREDIBLE HULK movie
Robert Bruce Banner was born on Thursday, December 18, 1969. As he grew up, he started going by his middle name. Bruce met Betty Ross while in college where they both fell in love. They soon graduated and moved on to work together at Culver University as instructors. Bruce later meets Erik Selvig, another one of the university's instructors.
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.
Eventually, 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.
An 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.
Three 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.

The Incredible Hulk The Fury Files
While Bruce is on the run, he goes into a bar, not knowing he is being followed by Nick Fury, who was trying to find Bruce and learn what General Thaddeus Ross' "Super-Soldier Program" did to him. He tried to earn Bruce's trust by buying him a beer but he refused, saying he is "sort of a mean drunk."
Fury continues to try to earn his trust, until he eventually tries to test his abilities by making two S.H.I.E.L.D. agents, appear to be dating and one is cheating on the other with Bruce which makes Bruce confused about the situation. The other starts to fight Bruce, but Fury tries to act like he's going to help him, but Peterson punches him in the face.

Seeing no end to his run from Ross, Banner heads up to Greenland to shoot himself. He shoots himself in the mouth but transformed into the Hulk, who spat out the bullet.
The Incredible Hulk:[]
Banner eventually settles in Rio de Janeiro, Brazil, working in a soft drink bottling factory while attempting to find a cure for his condition with the help of an Internet friend, "Mr. Blue". He also studies martial arts and meditative breathing techniques with a Brazilian jiu-jitsu expert to help control his emotions and heart rate, and has not suffered a transformation for five months.
After Banner suffers a cut, his blood drips into a soda bottle where it is eventually drank by an ill-fated consumer in Milwaukee, Wisconsin. General Ross uses this incident to discovers Banner's location, and sends a team to capture him, led by Russian-born British special operations expert Emil Blonsky. Following a ferocious battle in the soft drink bottling plant where he transforms into the Hulk, Banner escapes Blonsky, and ends up in Guatemala.
Going Back Home
Banner travels to the United States, where he sees that a now-recovered Betty is working at Culver University again and is dating psychiatrist Leonard Samson. He also sees his old friend Stanley, a pizzeria owner, who gives him a job as a delivery boy. Banner uses this job to sneak past a security guard to continue his research. After Betty visits the pizzeria and sees Bruce, she later reunites with him and gives him the missing pieces of their research.
Battle at Culver University
Emil Blonsky reports to General Thaddeus Ross that Banner evaded them in Brazil due to the appearance of a large green monster. Ross explains that the monster is Banner, and that he was created accidentally during an experiment in radiation-resistance that was inspired by World War II era military bio-force enhancement research (or "Super-Soldiers", as Blonsky puts it). Blonsky, seeking both revenge and power, volunteers as a test subject in order to capture Banner. He receives a small dose of the mothballed original Super Soldier Serum, created by Dr. Reinstein for Weapon Plus. He leads an assault on Banner at Culver University, during which Betty Ross is knocked unconscious. Despite Blonsky's increased strength, speed and agility, Hulk crushes most of the bones in Blonsky's body. Hulk saves Betty from an explosion and escapes with her to the Smoky Mountain National Forest.
Meeting Mr. Blue
Banner and Betty Ross then travel to Grayburn College in New York City, where they meet "Mr. Blue", Samuel Sterns. Accompanying Sterns to his lab, Banner and Betty learn that Sterns has developed a possible antidote that may cure Banner's condition, or merely reverse each individual transformation, while an overdose could kill him. Despite the risks, Banner agrees to test Sterns' antidote and is restrained and transfused with the cure mid transformation, after being electrically induced into transforming, successfully returning him to normal. Exhilarated by the success of the antidote, Sterns reveals that he has synthesized Banner's blood sample into a large supply with the intention of using it to enhance the human condition to the next evolutionary level. Appalled by what Sterns had done and fearful of the Hulk's power falling into the wrong hands, Banner attempts to convince Sterns to immediately destroy the blood supply but is shot by a tranquilizer from one of General Thaddeus Ross' snipers.
Duel of Harlem
As both Banner and Betty Ross are taken into custody, a freshly healed Emil Blonsky, seeking the Hulk's power, demands Samuel Sterns subject him to a transfusion of Banner's synthetic blood. Sterns warns that the combination of the Super Soldier Serum and the Gamma Radiation in the blood would be an unpredictable combination that could turn him into an "Abomination". Blonsky is less than concerned about this, and Sterns promptly administers the transfusion. As Blonsky mutates into the monstrous Abomination, he knocks Sterns aside and an irradiated sample of Banner's blood-derivative drips into an open wound on Sterns's temple, causing his cranium to mutate and expand.
In an attempt to draw the Hulk out, the Abomination goes on a rampage through Harlem. Banner, realizing that he is the only one who can stop the Abomination, convinces General Thaddeus Ross to release him. He jumps from Ross' helicopter as it hovers over the city, hoping the fall will stimulate his adrenal glands into triggering a transformation. Banner's plan succeeds and after a brutal battle the Hulk manages to defeat the Abomination by strangling him with a huge chain, though he releases his grip after a plea from Betty. The Abomination collapses, and the Hulk flees the scene with the Army in hot pursuit.
RUNNING AGAIN
Gaining Control of the HulkThirty-one days after his fight with Abomination, Banner arrives at Betty Ross's cabin in Bella Coola, British Columbia. He leaves Betty a note along with a necklace that he reclaimed after she had to sell it. Now more focused on gaining control over his transformations into the Hulk, and the Hulk itself, Bruce enters a meditative stance. His eyes turn green as he pushes his heart rate higher and a grin appears on his face, showing that he had embraced his other half and gained at least some partial control over the Hulk.
