Iron Man 3 isn't just the movie where Tony Stark blows up a few dozen suits for a romantic gesture — it's also our first glimpse of another Marvel character, Man-Thing!
SuperPunch pointed out a very interesting fact that we completely blanked on. The the female AIM agent (played by Stephanie Szostak) is named Ellen Brandt. And that's the name of Man-Thing's wife in the comics. She even has the same scar on her face.
Man-Thing was originally a scientist doing plant-based experiments, who is eventually betrayed by his wife (they fight, hence the scar) and she leaves to join AIM. This isn't terribly new news — Next Movie spotted this last year. But hey, it was new to us, so why not share? So we've met Man-Thing's wife, and glimpsed the aftermath to the movie version of his origin story.
Technically, Lionsgate owns the rights to Man-Thing, so it's probably not official that this was Man-Thing... but it totally was Man-Thing.
