First Appearance: Tales of Suspense #39 (March 1963)
Created by: Stan Lee, Don Heck, Larry Lieber, and Jack Kirby
To simply list all of Tony Stark's armor in one sitting is a post unto itself. Here's a rundown of what armors made it to the movies. First, his Mark I armor from Iron Man was done pretty well, although in the film he switches to his sleeker, modern-looking armor pretty quickly, in the comics he stayed that way for a while, looking like the precursor of Bender from Futurama. In fact, in the first Avengers comic, the only makeover he got was a gold color on his bucket-like armor.
The Mark III armor more accurately represents his classic comic appearance, with the red and gold color scheme. In Iron Man 2, Tony dons a silver and red suit that transforms into a briefcase. The color scheme pays homage to the comics' Silver Centurion armor. When he redesigns his armor to the Mark VI, he implements the triangular chest plate from the comics' Extremis armor, which was what Stark was rocking in the books around the time the film came out. In The Avengers, the new Mark VII suit returns to a circular chest plate inspired by Iron Man's classic look, and cool features like shoulder-mounted rocket launchers.
