Re: Iron Man needs to stop fighting evil Iron Men
Iron Man will be fighting alongside a super-solider, a gamma-spawned monster and a Norse God, among others, in The Avengers. The idea that the Mandarin et al are too outlandish for the tech-based Iron Man of the movies won't make much sense after that.
There is no Marvel/DC rivalry. Most of the great comic creators worked for both; Jack Kirby, Frank Miller, Grant Morrison, Walt Simonsen, Gil Kane, Steve Ditko, John Byrne, Steve Englehart, Mark Waid...even Stan Lee.
