[Trivial Psychic]

To answer your questions Kylactus, these are both straight up repaints, with nothing really new added in terms of mold or articulation. The Xeno is the NECA Big Chap figure, (the newest version) with a slight silver paint wash, along with a completely painted over dome, whereas the original Big Chap's was see through, to show off the skull underneath.

The Predator is simply a repaint of Renegade, and therefore is the same figure as the 25th Anniversary Predator, (or whichever one it was that debuted the new articulation in the legs...forgive me, takes a bit of energy to get up and check.) It wouldn't kill you to skip out on the set if you are looking to army build some Xenos, especially now that the two pack red and black Xenos are popping up at decent prices as well as the dog alien still being out there. (although army building Big Chap at this point might be expensive since he has been out for a while, and you know how the secondary market prices tend to be with retired NECA stuff.)
