Hulk

The Incredible Hulk, from 2008, stars Edward Norton. The origin flies by in the opening credits: a gamma radiation experiment, tied to a military super-soldier program, goes wrong, and Banner destroys the lab and injures his girlfriend, Betty Ross. Her father, General Thaddeus Ross, starts hunting him.

When the film begins, Banner lives in Rocinha, in Rio de Janeiro, works at a soda bottling plant, and practices breathing to control his heart rate. A drop of his blood falls into a bottle, and the trail leads Ross to him. On the run, Banner returns to the United States, reunites with Betty, and seeks out a scientist he's been messaging, Samuel Sterns.

Ross turns soldier Emil Blonsky into the Abomination, who tears up Harlem. Banner jumps out of a helicopter to turn into the Hulk on purpose and defeats the creature. At the end, he's isolated in Canada, trying to control the transformation. Starting with The Avengers, the role goes to Mark Ruffalo.

In The Avengers, Natasha Romanoff finds Banner working as a doctor in Kolkata. He agrees to help locate the Tesseract. Loki triggers the transformation aboard the S.H.I.E.L.D. helicarrier, and the Hulk nearly kills Natasha. In the Battle of New York, Banner shows up on his own, tells Cap the secret is that he's always angry, and turns into the Hulk on the spot. He's the one in the scene where Loki gets slammed into the floor like a rag doll.

In Avengers: Age of Ultron, Banner helps Tony Stark create Ultron, and carries that guilt. Natasha manages to calm the Hulk with a gesture they worked out, and the two start a romance. In Johannesburg, the Scarlet Witch messes with Banner's mind, and the Hulk wrecks part of the city until Tony stops him with the Hulkbuster armor.

After the battle in Sokovia, the Hulk refuses to change back, gets into a Quinjet, and disappears.

Thor: Ragnarok shows where the Quinjet went: Sakaar, a junk planet ruled by the Grandmaster. There, the Hulk becomes the arena champion and goes two years without letting Banner come back. He talks in short sentences, has his own room, and doesn't want to leave. He fights Thor in the arena, and only a recording of Natasha makes Banner reappear.

Banner is afraid that next time he won't come back. Even so, he turns into the Hulk again to help defend Asgard.

In Avengers: Infinity War, Thanos beats the Hulk in a fistfight on the Asgardian ship. Heimdall sends Banner to Earth, where he crashes into Doctor Strange's Sanctum and warns that Thanos is coming. After that, the Hulk refuses to come out. Banner fights in Wakanda inside the Hulkbuster armor and survives the snap.

In Avengers: Endgame, five years later, Banner shows up with the Hulk's body and his own mind. He explains he spent 18 months in a gamma lab until he merged the two halves. In the time heist, he goes to New York in 2012 and convinces the Ancient One to hand over the Time Stone.

Since he's the most resistant to gamma radiation, he's the one who puts on the gauntlet the team built and snaps his fingers to bring back everyone who vanished. His right arm is left burned.

In the post-credits scene of Shang-Chi and the Legend of the Ten Rings, Banner appears in human form with Wong and Carol Danvers, studying the ten rings and the signal they're giving off.

In She-Hulk: Attorney at Law, a car accident causes Banner's blood to contaminate his cousin, Jennifer Walters. In episodes 1 (“A Normal Amount of Rage”) and 2 (“Superhuman Law”), he tries to teach her the control it took him years to master and then leaves for Sakaar on a ship. He returns in episode 9 (“Whose Show Is This?”) with Skaar, the son he has on that planet.

Thaddeus Ross, the general who hunted Banner in 2008, becomes President of the United States in Captain America: Brave New World, now played by Harrison Ford. Manipulated for years by Samuel Sterns, he turns into the Red Hulk and fights Sam Wilson in Washington. In the end, he turns himself in. Banner doesn't appear in the film.

In Spider-Man: Brand New Day, Banner teaches at a university and wears an inhibitor that keeps the gamma radiation in check so he stays human. Peter Parker seeks him out because his own powers are changing, and uses the device as inspiration to build an inhibitor for himself.

The telepath Jean Grey takes over Banner's mind and removes his device. When she loses control, something inside him breaks and the savage Hulk returns, bigger and with none of Professor Hulk's calm. The fight with Spider-Man is brutal. The Hulk only calms down when Peter says his own name and tries to reach the Banner inside.

The Hulk debuted in The Incredible Hulk #1 in 1962, created by Stan Lee and Jack Kirby. In the first issue he was gray, and he turned green soon after. In the comics, Banner is caught in a gamma bomb blast while saving a young man named Rick Jones, and the Hulk's many personalities have been explored for decades.
