I've always wanted a full body predator costume, but being within reason I'm probably only going to put some predator action figures on my Christmas list for AvP stuff, specifically the NightStorm Predator and the Predator Hound.
The Stalker biomask (and all the other masks) would be nice to have, but honestly, I don't want it for Christmas if you can't put it on (and, sadly, you can't).
If someone got me the Aliens Omnibus, that'd be cool.
I always liked the Queen alien plush, also Zero, check ebay.com for a queen and king alien action figures, I actually have a queen I got off of there for $12 USD.
I want one for free not to pay for. I don't have that much money you know. I have been using it on PSN cards and lunch. I also just bought two alien comic books and I also got AVP onibus.
I hope I can get the Chinese toy in the toyswill.com, look so interesting and representative.
