You wouldn't think it was true now, but before his first movie came out, Iron Man was strictly a B-List hero. You would struggle to find anyone outside the comics fandom who could tell you much about him beyond the basics and the fact that he had a fairly average 90's cartoon series with a disproportionately awesome theme song.
Flashforward to today and, mostly thanks to a hell of a performance by Robert Downey, Jr, Iron Man is one of the most popular heroes on the planet and a cornerstone of the Marvel empire.
Tony Stark is much more than just a movie character though and he has a rich comic book history stretching back to the 1960's. Modern comics have portrayed him pretty closely to the version on the big screen, but Iron Man has gone through a lot of iterations over the years. This has lead to some interesting titbits and trivia that most people might not be aware of.
