Captain America: Civil War

Captain America returns in his third movie, "Captain America: Civil War," which tells the intense conflict among Marvel superheroes, split into two factions over government legislation.

The contentious regulation is the Superhuman Registration Act, instated after the superheroes' actions led to significant destruction in the city. This law limits the superheroes' autonomy in their operations.

Team Iron Man supports the regulation, aiming to minimize collateral damage to the city and its inhabitants. Conversely, Team Captain America opposes it, believing that their world-saving missions are unpredictable and entail various risks, making it impractical to be constrained by government oversight.

This disagreement escalates into a fierce battle between the two groups. Team Iron Man comprises Iron Man, Black Panther, Vision, Black Widow, War Machine, and Spider-Man. On the other side, Captain America's team includes Captain America himself, Bucky Barnes, Falcon, Scarlet Witch, Hawkeye, and Ant-Man.
