Iron Man
Even from the very first Iron Man movie, the Marvel films were never against the War on Terror - Tony Stark and Iron Man represented the kind of war that liberals wished they could fight, where the bad guys get blown up and the technology is so good that no civilians are harmed. Compare Iron Man's sleek, smart suit to Jebediah's knockoff at the end of the movie, which is much bigger, and it perfectly mirrors the liberal conception of a good war as being one fought with drones and special forces instead of a big military occupation.
