Looks nice. In the description it says for the Ultimate Big Chap that its an all-new sculpt which is a blatant lie, FYI. The body is a complete reuse of the Blue Kenner Alien, just to clear things up. Furthermore, the only difference from the previous Big Chap will be the removal of the bicep swivel and the addition of new double jointed elbows and knees, and a swivel at the base of the tail. The paintjob will be new. The dome seems too translucent, again and this time if the prototype in the pictures is anything to go by, the dome doesn't sit well on the front of the skull. The minor problems are fixable, but will be annoying if present. The egg, hugger and burster are nice though. And we're not sure if he'll be getting the extra neck joint, the pictures certainly don't support it, but the final products tend to differ often with the paintjob and sometimes by having more articulation. We'll see.
Dog alien looks nice, will be getting him, those added knee joints will be of great use and the accessories are awesome.
P.S. I love how they literally mist the figures to give them more of a wet look during a photo shoot. But it's the dry heat...
