I'm gonna have to go with Extremis Iron Man too.

The looking up body is a nice touch, and his core body and arms can be used for tons of kitbashes or figures. Iron Patriot, Nova (new legs, new head, IM2020 like chest for full nova prime effect), Dark Hawk (new legs, tweaked head, and wraith gauntlets to add wings with), and more.

Otherwise I gotta go with ultimate cap, 2010 wave 3 colossus, or Thor. Thor's cape especially I thought was an awesome way to add it in.

It's hard to just pick one. Especially as each wave progressively gets better and closer to one upping my Motion Revive Kamen Riders in articulation. (Only double elbow joints different now it seems, besides the double shoulders that make it hard for limbs to stay on.)
