2. Hulk Sucker Punches Thor (The Avengers)
In one of the more epic single-shot fight sequence in the Avengers, Iron Man is seen taking out several Chitauri soldiers, before Hawkeye shoots one of their pilots in head, causing it to crash in to a giant space whale which both Hulk and Thor (who had previously battled each other) are on top of, taking on an army of the soldiers. When Hulk rams a large chunk of metal in to the giant creature's back, Thor strikes the metal with lightning, taking the creature down. The shot then switches to the creature crash-landing through the wall of a New York building and coming to a stop inside. Hulk and Thor step down from the wreckage, standing tall after their successful team-up and Hulk (who clearly remembers the fact that they had fought each other earlier) humorously gives Thor a strudy left jab, sending the Asgardian flying, before letting out a satisfied grunt.
