Astonishing Wolverine finally. You can tell by the boots for sure. And he looks like he has swivel hips, maybe balled ones. I wonder if it's the XMO mold with a new masked head?

The other two have me stumped.
90s US Agent is all that comes to mind for the shield. The no head fins, no boot straps, and no glove straps throws me off, especially since it has a skullcap still, but it's odd shaped, like Iceman's head almost. Or Ultimate Cap's head.

The bucket head one has no distinguishing marks either that I can tell, besides the helmet. Tight boots, and sorta big gloves. Maybe hair coming out the top.
Hercules is the only one I can think of that might fit that.

So I'm officially stumped by these two.
