Roxxon Corp.
To truly appreciate easter eggs in the MCU, you’ll have to use more than the other movies in the universe as your references. The comic books go so much deeper than what you see on screen, and there’s never enough time to go through everything. We wouldn’t mind there being 50 Iron Man movies if they could go through every detail in the comics!

One example of how a comic book reference didn’t play a huge role in the movie was during the fight scene between Iron Man and Iron Monger. In the background, you can see the Roxxon Corporation building, which is a huge evil corporation in the Iron Man comics.
