With AvP2 coming out this year, I imagine a Predalien will be the hot-topic. I’ve created a profile page for the creature which covers its introductions in the comics to the games and now to the movies. It’s worth a read and hopefully gives people an indication as to what we can expect from Alien vs Predator 2.
I personally think one of the major problems with the Predalien is that everybody has a different opinion on what it should like. Let’s hope, ADI have done a decent job at creating the creature in AvP2 with a design that pleases the majority of people.
