Roger: To continue the conversation from Facebook about Iron Man Legacy, I was mistaken. The Mark IV armor only appears on the covers and not in the actual book, so I think we would all agree that does not count. However, I did find some armors in the first 5 issues of the mini that are not included in the handbooks. These are all from the first 5 issue arc of the series.
The first is a the Subterranean Armor that I had mentioned, the hands transform into drills, but the full page of that is huge, so I didn't want to post it. It appears to borrow its appearance from an action figure from the first movie:
The next is another big powerhouse type armor. As far as I can tell, this thing doesn't do anything special except be large, but it's there in the series..
The final one is the one that could really throw a monkey wrench into things. There's a one panel flashback to Tony building the armor in the cave.. And well.. I'll let the picture do the talking:
So according to Iron Man Legacy, Tony build the Mark I while captured. This is a change that I would actually be okay with. I really like the hodgepodge of parts on the Mark I that truly makes it feel like it was assembled in desperation. Then the idea would be that the Model II wouldn't have been simply a repainted version of the Model I, but a whole new armor entirely. I don't hate this concept, as it makes sense then that Stark would make upgrades to the armor when he got home.
As I mentioned on Facebook, my research was from 2012 onward, since Iron Man had received an updated profile in the 2012 Avengers Roll Call Handbook. The 2012 update was only a page, however, so due to space limitations, we didn't include information about anything other than the current armor he was wearing. Debate on Iron Man Legacy being canon aside, that's bad on my part, and I humbly apologize. (I blame Fraction, however, because he actually drove me away from Iron Man for awhile, and had I stayed a vigilant reader, I would have remembered all those details. Yeah, that's my story).
That said, hypothetically speaking, let's assume Legacy is in continuity. So, where would the two specialty suits noted above fall chronologically in Iron Man's history? And that, unfortunately, illustrates why a hard numbering system for Iron Man armors is a pain in the ol' keister. At any time, a writer can retcon in a special suit that, like a time travel ripple effect, completely messes with anything that comes after it.
As for the first suit, I call artistic license on that. The MCU version of Iron Man's armor is massively cooler looking.
