The Story of Bruce Banner/Hulk (Marvel Cinematic Universe)

Chitauri Invasion: Attack on the Helicarrier

Before Banner could inform the team of the Tesseract's whereabouts, the brainwashed Hawkeye led a team of mind-controlled soldiers into the ship and destroyed one of the engines, causing an explosion that resulted in Banner and Black Widow falling into the weapons cache room. The explosion prompted Bruce to begin transforming into Hulk. While Bruce had learned to retain control during intentional transformations, his attempt to repress a transformation and subsequently failing resulted in Hulk emerging without him retaining control. As Natasha looked on in horror, Hulk chased after the agent, attempting to kill her. Although she managed to evade him for a long time, Hulk was able to catch up to her and throw her against a wall.

Before he could kill Natasha, Hulk was intercepted by Thor. As Hulk's rage increased during his fight with Thor, he was able to survive direct hits from Mjølnir and throw the Asgardian across the room several times. He ripped the wing off a fighter jet and hurled it at Thor. During the fight, Hulk attempted to lift Mjønir, but even with his incredible strength, he was unable to move the hammer, which only increased his rage.

As the fight got more intense, Nick Fury and Maria Hill were left with no other choice than to send a fighter jet to shoot at Hulk, as they feared he would destroy the Helicarrier and kill everyone aboard. When the jet began firing at him, Hulk's enforced skin was able to deflect the bullets leaving him unharmed. Outraged by the attack, Hulk roared, left Thor and leaped at the jet. He was able to rip it apart in the sky causing it to spin out of control, the pilot attempted to eject, Hulk caught him and threw him across the skyline, fortunately, the pilot survived. As the jet exploded, Hulk fell from the sky, crash-landing into an empty warehouse.

Hulk eventually transformed back into Banner and woke up naked in the warehouse. A security guard at the warehouse informed Banner that he did not harm anyone during his crash-landing and that he believed that Hulk had controlled his fall to prevent casualties. The security guard then asked him if he was an alien, to which Banner assured him he was not. Giving Bruce clothes, the guard asked him if there was someplace he had to be. Deciding to help the Avengers, Bruce informs the man that he needs to go to New York, and the guard allows Bruce to use his motorcycle.
