Because Predators are the ultimate hunters, a werewolf would nob be able to sneak up on one with ease. A Xenomorph was able to simply because the Predator was already preoccupied, inexperienced, and the Xenomorph new the area.You're missing the point. Imo the werewolf from vanhelsing or underworld for that fact has about the same speed as the xenonorph imo, but its no contest that they are even stronger than them, they're known for there brute strength, on top of the fact that there sight, smell, and hearing is all on super human levels, I don't see how a werewolf can't easily manuver itself behind a predator and end him with a bite that would easily rip him apart.
