First appearance: Iron Man #72 (2003)
In 2003, Tony Stark was appointed Secretary of Defense and decided to upgrade his armor to be able to do battle with the world's political climate. This is when his look really began to morph into the style that we see in the movies. Sleeker and more functional than ever, this armor was built more like a military jet than a traditional Iron Man suit.
One of the most interesting aspects of this suit is the fact that it was built of tiny plates that become magnetized in order to literally snap into place onto Stark’s body on their own. It was an impressive suit during a time when the character was finally clawing his way back up from the ‘90s abyss.
