Bruce Banner grew up in an abusive household. Both of his parents ended up dead, and while Bruce had a brilliant mind, he was also left psychologically scarred by his upbringing. He became a scientist with an expertise in gamma radiation. During the testing of a gamma bomb for the military, Bruce entered the impact zone to save an unaware Rick Jones from harm, causing himself to be hit by the blast. It changed him, causing him to transform into a mindless, rampaging "hulk". He was initially gray-skinned but this soon changed to green. Bruce's lack of control as the Hulk can be attributed to a form of Dissociative Identity Disorder he developed, where he has multiple different personalities, some of which only emerge when he is transformed. These identities include Bruce himself, the Savage Hulk, Joe Fixit, the Professor, the World Breaker, and the Devil Hulk. Bruce is fairly tragic as Marvel characters go, a brilliant scientist who due to past trauma is rarely able to establish a stable life for any length of time before his demons catch up with him. He has tried to cure his condition multiple times but he has not succeeded.
Hulk's volatile nature leaves him often at odds with others in the superhero community. He has been a member of the Avengers, Defenders, and Fantastic Four, but his episodes of blind rage often have him fighting his allies as much as he helps them. In the 2000s, the aforementioned Illuminati took the drastic step of tricking Hulk into entering a space vessel that took him to another planet far across the galaxy. It was there that he became a gladiator and then led an uprising to become a king in the Planet Hulk storyline. After one of his supposed allies sabotaged the ship he came on, leading to his queen's death, Hulk blamed it on the Illuminati and returned to Earth to kick all their asses in World War Hulk. More recently, Al Ewing wrote the Immortal Hulk series, which is more of a horror story than a superhero one, and is one of my favorite comics ever. In it, the various gamma-powered characters discover the Green Door that separates life and death, and what happens when the door stays open.
Hulk has a long history in TV and movies. In the 70s there was a live action series with two different actors depicting Bruce (renamed David) and Hulk, which continued with a series of TV movies in the 80s. In the 00s Ang Lee released Hulk, one of the most idiosyncratic superhero movies ever, to mixed success. It's certainly interesting. In the MCU, The Incredible Hulk is more traditional but not much better, and there hasn't been a solo Hulk movie since, but Mark Ruffalo has appeared frequently as the character, giving him that Ruffalo charm and depicting a more fun take on the character. The Hulk is a character who is constantly changing, moving from a completely in-control and capable hero to an unstoppable and unpredictable force of nature at the drop of a hat. He can basically be whatever a creative team needs him to be at a given moment, which leads to flexibility but also a lack of consistent identity. He's definitely unique, and the Marvel universe is richer for his presence.
