3. The Bleeding Edge Armor
Matt Fraction and Salvador Larroca’s run on Invincible Iron Man was one of the best ever. In fact, I’ve written extensively about it, because it was just so great, you guys.
After he survived Norman Osborn’s takeover of S.H.I.E.L.D. in World’s Most Wanted, and Tony’s own return to sanity in Stark Disassembled, Iron Man needed a new armor. So we got the beautiful Model 37 Bleeding Edge armor. The suit was all nanotech, and it was stored inside Tony’s very bones – which, while creepy, was also cool.
During the Fear Itself event, it was ingrained with uru metal, which turned it into the Iron Destroyer armor. Interestingly enough, its power source was Stark’s RT node, which was implanted in his chest.
This armor lasted Stark through a great many events. It faced off with Magneto during Avengers vs. X-Men, opened up the Heroic Age, and survived Spider-Island and Ends of the Earth. An all-timer.
