Hulk

"Dr. Banner, now it might be a really good time for you to get angry." "That's my secret, Cap.... I'm always angry."

- Captain America and Dr. Bruce Banner. The Hulk (alias Dr. Bruce Banner) is a superhero who is featured in both Marvel's 2012 live-action crossover film the Avengers and their 2013 film, Iron Man 3 (in his post-credit cameo). He is both portrayed by Mark Ruffalo and voiced by Lou Ferrigno in the films.

In the Avengers: Earth's Mightiest Heroes, the Hulk is a human being who was a scientist that was exposed to gamma radiation that allowed him to turn into a big green monster. He is one of the founders of the Avengers serves as the powerhouse of the team. He is also is a genius scientist on gamma radiation. His alter-ego Hulk is a result from a gamma radition accident.

Physical Description
The Bruce Banner persona has a rather weak build, while being chased by various people and little time taking care of himself. He has a scruffy beard, dark messy hair, and brown eyes.

When Bruce gets excited or angry, he grows into a large green man with large muscles. He also rips out of his clothes with only his ripped pants remaining. His eyes and hair turn green and his scruffy beard disappears.

Personality
Bruce is a genius as an expert in gamma radiation. He is overly sarcastic by guessing Hawkeye's joke. After having exposed to the gamma bomb he gained another personality that is monstrous, called the Hulk, that he can change into after his heart rate goes at a certain point by getting too excited or angry. He tries to maintain his heart rate by calming himself down,but it seems that he's able to bring out Hulk by will alone (it could be theorized that Bruce's heart rate is something he cannot always control, thus he can sometimes bring out the Hulk not by his will). Bruce cares for people especially ones that have been radiated with gamma rays, even trying to help Absorbing Man. Bruce distrusts S.H.I.E.L.D., as he thinks that they will use the gamma radiated mutants as weapons for themselves.

Bruce Banner is a really good and a very nice doctor who likes meeting new people especially Tony Stark and Steve Rogers. He is a brilliant scientist who Tony Stark likes and he makes great work which makes him a great scientist as well. Given that Bruce Banner also sometimes can feel a little upset or angry and depending on what he's feeling. When he transforms into The Hulk then that means he's angry and he's not happy at all. But Bruce Banner is a very nice guy and always helps out even when it's very difficult for him to fit in with other people. He is known to also be very smart and intelligent and he knows what he's doing when he's performing experiments in his lab or workplace.

As the Hulk, he is very aggressive especially when he changed into the Hulk when he was angry, after changing into the Hulk he causes destruction to his surroundings and beats anything in his path, however, he has a soft spot for animals. After some time, Hulk respected people and had the thought of help them instead of hurting them, such as when the Hulk rescued Hawkeye's men from a helicopter crash. Hulk can talk with Bruce as his dormant persona and decided to join the Avengers to help innocent people and show them that he can be good in exchange for staying as the Hulk. Hulk is very egotistical when it comes to his fighting prowess calling himself the strongest there is and laughing at Hawkeye when he said he could take him down. He can get along with people very well, but can be easily irritated by others if they think that Hulk is only a monster.

In some appearances, Hulk shows a trait to call people by nicknames that he comes up with, like calling Thor "Goldie Locks", Thing "Rock Man", Spider-Man "Bug-Man", Wolverine "Little Man" and Hawkeye "Cupid".

Powers and Abilities
Transformation: Due to the Gamma Radiation that has mutated his body, Bruce Banner is able to transform between his normal, unpowered human form and the form of one of the most powerful superhumans. Bruce can activate by force of will. In addition, this transformation has led to a dual consciousness, with one being Bruce Banner and the other the Hulk. As of now, the Hulk is in charge of their shared body. He has only transformed back into Banner a handful of times.

As Hulk
Superhuman Strength: As the Hulk, he has virtually unlimited superhuman strength at his disposal.

He is easily able to heft objects like tanks with one hand and use them akin to a baseball bat. This strength also allows him to leap incredible distances. The Hulk's strength increases when he is angry, and this is something that has led to the downfall of many villains.

Early life
At some point in his life, Bruce Banner was a brilliant scientist who was doused with gamma radiation during a freak accident, which enabled him to turn into The Incredible Hulk when under intense stress. The destructive behavior of his monstrous alter ego caused the U.S. Military, for whom he was working on the gamma bomb project, to start giving him chase. Because of this, Bruce has spent his days on the run, trying to keep a low profile in public places.

Hulk versus the World
He was last spotted in Las Vegas, NV. In a diner on the city's outskirts, he approached Carl Creel, a.k.a. Absorbing Man, and tried to talk the villain into helping him out, promising to heal his condition in return. Instead, Creel attacked him, as he knew that Bruce was the Hulk. This resulted in a full-scale brawl on the Nevada desert, which culminated with S.H.I.E.L.D. interfering. In spite of the Hulk's efforts to avoid any casualties (even going out of his way to save S.H.I.E.L.D. operative Barbara Morse), he was incapacitated and taken under S.H.I.E.L.D.'s custody.

The Breakout
In the Cube, Bruce is locked up in his cell. Samson visited him, to tell him about his condition and the curing of the other persona. Bruce was worried about the Cube prison and warned Samson that he is being used by S.H.I.E.L.D.

After a blackout happened, an explosion occurred freeing Bruce, but still captivated by the boulder that fell on top of him. He is soon freed by gamma radiated Samson. Zzzax approached them and knocked Samson out and zapped Bruce, making him angry and transformed into the Hulk. Hulk took care of Zzzax and carried Samson, he encounterd Abomination and Absorbing Man and fought them for a while and escaped the prison along with Samson.

Hulk went to the Vital diner and brought Samson to the waitress. He watched the news of the fight between Graviton and Thor and was interrupted by Banner in his own vision. He agreed with Banner to become a hero despite being known as a monster, in condition having control of the mind.

When Graviton attacked the city, he came to the rescue and took on the villain Graviton. With his strength and density could overcome the gravitational powers of the villains and along with Wasp, Ant Man, Iron Man and Thor crumbled Graviton to his knees. After they defeated Graviton, they were approached by the S.H.I.E.L.D. who were going to take Hulk and Graviton. The Hulk was defended by Iron Man and was considered to be a hero. The heroes together by Iron Man's suggestion formed as a team and by Wasp's name suggestion became the Avengers.

Avengers
After becoming the Avengers he was invited to see the Avengers mansion where he would stay with Thor. Hulk arrived in time for the tour complaining about the others late arrivals. At the tour around the mansion, he took on the training sessions and succeeded. He along with the others arrived at the assembly hall, he talked with Bruce inside his mind, putting suspiciousness to the other Avengers. The Hulk argued with Thor about his behaviour and left to his room. Bruce wanted to contact him but was sealed by the Enchantress. With Hulk becoming enraged, he decided to quit and after talking with Thor he left the mansion.

Hulk walked through the city scaring people around him, he was approached by Thor who wanted him to return to the mansion. Hulk pitted in a fight against the Asgardian. The other Avengers arrived and tried to calm Hulk down, but by Enchantress' spell, he was on a rampage. Before Hulk could finish the Wasp off, Bruce released himself from Enchantress spell and the Hulk went calm. He realized what he has done and left the scene. He discussed with Bruce who consoled the Hulk and made him return. The Hulk fought against the Enchantress and the Exeuctioner, with the latter trying to control him and Hulk freed from the spell. After the enemies fled, Thor tried to convince the Hulk to stay, but Hulk still decided to quit the scene and leaves. He went to the Artic to relieve his anger.

Gamma World
The Hulk arrived in a forest, where he was ambushed by the Hulkbusters. He fought them off until Hawkeye arrived and they stopped their attack. Hawkeye threatened the Hulk to let Bruce Banner out, but Hulk responded in laughter and transformed back into Bruce. Hawkeye explained about the Gamme dome and Bruce devised a plan where they would defeat the Leader and gave Hawkeye an antidote to the gamma radiation. Bruce transformed back into the Hulk and left towards the headquarters of Leader.

At the headquarters, Hulk was offered to work alongside Leader to rule the world with gamma mutants. Hulk rejected the offer and wanted to smash him. At the dissappointment of the Leader he ordered Abomination to ambush the Hulk. He fought off against Abomination with the equipped gamma radiation receiver and was nearly beaten by him, but was rescued from Hawkeye who used the antidote of the Gamma radiation. Abomination depowered and Hulk punched him to the vast reaches of the dessert. The Hulk stood against the Leader in his battlesuit, but were interrupted by Absorbing Man who landed on the armor, after Thor arrived Hulk destroyed the Atenne releasing the gamma dome.

Hulk along with the others went to the site of the Sentry-459, they attacked the robot, but was nearly indestructible. After Wasp took care of the robot from the inside, the mega bomb was set to detonate the whole planet, which Hulk arrogantly claimed that he could survive.

Hulk along with Hawkeye was about to be ready to leave, but was stopped by Captain America who convinced them to stay and accepted it alongside Hawkeye and Wasp and became the remaining Avengers.

Thunderbolt Ross
General Ross is the Hulk's archenemy. In leading the Hulkbusters, he was so obsessed in capturing or possibly destroy the Hulk over the years whatever means necessary. Hulk hates him more than Ross hates him.

Banner transforms unwillingly despite Romanoff's efforts to calm him down and ends up falling off the helicarrier after causing much destruction and even throwing down with Thor. He eventually transforms back to Banner to find himself having been watched falling by a man. The man gives Banner new pants.

As the two continued fighting, Hulk threw Spider-Man, who retaliated by webbing the front of his face. Hulk warned Spider-Man to "turn on the lights" or else he would get more destructive. Hulk got the webbing off of his face and was shot at by police officers. This would further to prove that Hulk was misunderstood and only seen as "terrible" and a "menace" by everyone because of how he looks.

Teaming up with Hulk, Spider-Man had helped defeating Zzzax and protected Hulk from S.H.I.E.L.D. arrest. Before Hulk left, he commented that humans are dumb except for "bug-man". As Mary Jane questioned the Hulk, he said "Hulk hate interviews." then left.
