Oh yeah, I forgot about the Naussican. I do have that one, along with the Klingon whose name is escaping me. I never got Silik. I wasn't a fan of the Suliban. The Naussican and Klingon can at least pass for classic aliens.
I never got the First Avenger version of Cap, so I can't compare it to that. This is one truly awesome figure. I do have a couple nits. The outfit restricts articulation a bit, and the belt has a terrible clasp in the back. Those don't really affect how it looks, though. My picture of the unmasked sculpt make it look awful, but it looks much better in real life. I was also surprised to see that the Chitauri gun is actually a hand. It plugs into a wrist ball instead of being held. I can't wait for the whole team. That's going to be one amazing display.
