I don't think the Iron Man is a Legends figure, he's shorter than the Sentinel and that Sentinel is the same as this listing

Giant-Sized X-Men Marvel Heroclix - Sentinel Mark II Exclusive Version - Heroclix Marvel Heroclix

Which they claim is more than 5". Which means I was wrong on my estimate for FFF's height, he's closer to 12"-13" than 16". Hard to tell without exact measurements. I still think its a good stand in if you don't want to shell out the money for Legends FFF.

Edit: Archivist beat me to it.
