So far we've had in MU at least,
Classic,
Classic Finned,
Modern wave 1
and Extremis 2010 series 2

Extremis 2010 after recent comparings seems to be his armor from (Ironman V5 2009)dark reign right before he escaped in the classic armor. Is this his extremis, skin, or civil war armor?

Where's his modern armor fit in from wave 1? Issue of use? I haven't gone back enough, but it doesn't look like it in X-Men when they discovered icarus' body(civil war).

Ironman 2 hasn't shown anything noteworthy yet in way of modern ironman, just mk1, classic, and war machine so far out of stark's armors. But may need identifying on those later as well, or if anyone has questions about other figures like ML or Icons/masterworks whatever other lines.
