Meh... in terms of purely looking like a Predator, Scar's head is closest.
That and the fact that I can't stand Wolf...
And think about it for a second, what if Predator 2 didn't come out until now? You guys would likely accuse the P2 of not looking like a true Predator. Don't deny it, you know it's true.
Wolf does suck loads!
My problem aint so much it does not look like original as I dont mind the others inc Scar and Berserker. Its just Wolf is a bad design choice.
