"Sorry, kids. You don't get to see my little party trick after all."

- Dr. Bruce Banner referencing to The Hulk

The Incredible Hulk (real name Robert Bruce Banner) is a superhero who is featured in Marvel's 2008 film, The Incredible Hulk, and 2012 live-action film The Avengers, and their 2015 sequel Avengers: Age of Ultron. He also has starring roles in Disney animated series such as The Avengers: Earth's Mightiest Heroes, Avengers Assemble, Hulk and the Agents of S.M.A.S.H. and guest stars in Ultimate Spider-Man.

Hulk was created by Stan Lee and Jack Kirby.

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.

The Bruce persona is that of a kind doctor who likes meeting new people, such as Tony Stark and Steve Rogers, although he is not without a sarcastic side. He is a brilliant scientist whom Tony Stark likes and he makes great work which makes him a great scientist as well. Given that Bruce 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 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. He can get along with people very well, but can be easily irritated by others if they think that Hulk is only a monster.

Powers

 * Transformation: Due to the Gamma Radiation that has mutated his body, Bruce is able to transform between his normal, unpowered human form and the form of one of the most powerful superhumans. Bruce has trouble with this ability as it only activates by pure aggression and requires force of will to summon it. In addition, this transformation has led to a dual consciousness, with one being Bruce and 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.
 * Superhuman Strength: As the Hulk, Bruce has virtually unlimited superhuman strength at his disposal. He is strong enough to match his teammate Thor in combat, as well as break through the incredibly powerful gravitational influences of the villain Graviton. He is easily able to heft objects like tanks with one hand and use them akin to a baseball bat. Frankly he is capable of picking up any object he wants to. Bruce's strength increases when he is angry, and this is something that has led to the downfall of many villains. His strength is only rivalled by Thor and most likely Thanos. He likely can surpass them in strength if made angry enough; as shown in Avengers Assemble, his most powerful form, referred to as "Worldbreaker Hulk" is capable of destroying planets, but allowed him to keep New York from sinking into the sea.
 * Superhuman Durability: As the Hulk, Banner possesses near-invulnerability toward all types of harm. He has been struck with bullets, laser cannons, powerful magical and technological energy blasts, and falls from great heights with no injury. His durability is similar to that of Thor, Ronan the Accuser, and the Thing.
 * Environmental Adaptation: As the Hulk, Bruce can adapt to any environment, even airless space. Bruce can adapt to a wide diversity of hostile habitats. Bruce can harmonize his biological structure with the depths of the ocean. He can even speak in these inhospitable habitats. Bruce can eat, drink, breathe and function normally in any environment. He does not need to eat, drink, or breath, and his ability to adapt to his environment is an inherent property, which is also enhanced and amplified by his rage, excitement, stress, and necessity.
 * Weaponizing: As the Hulk, Bruce had to make something useful out from any object and used them as melee and ranged weapons like tanks, missile launchers, signboards, cars on foes.
 * Accelerated Healing Factor: Hulk can heal even serious wounds within seconds.
 * Superhuman Endurance: Bruce's body generates no fatigue toxins during physical activity, granting him nigh limitless endurance in all physical activities. His stamina and vitality are inexhaustible and limitless.
 * Superhuman Stamina: Bruce's stamina and vitality are inexhaustible and limitless.
 * Superhuman Speed: Bruce is capable of running faster than a human; Hulk could even surpass an aircraft while on land, he can swim at 100 knots, and keep up with Emil Blonsky. His reflexes have even been described as "lightning-fast reflexes", fast

Trivia

 * In Avengers Assemble, Hulk has a collection of glass animals that he is very fond of, referred to as "The Zoo" by Iron Man and Captain America. Made for him by Glorian, an inter-dimensional craftsman, each one represents a different adventure he has had over the years. Anyone who breaks one of his glass figurines earns his instant wrath, as Hawkeye discovered to his dismay in the episode "Mojo World". Most of the Avengers have learned to steer clear of "The Zoo".
