Secondly, the Predators are very good hunters as their nickname implies . They don't need the infrared scanners to find people. It just helps. Even if Jason can't die the Predator should have no problem cutting him into so many pieces that he may as well be.
A wuss who beat the shit out of Freddy Krueger, survived in the vaccum of space, burned up in Earths atmosphere and regenerated, shot point-blank with an RPG and survived, and has the highest body count out of all horror villains, up to 200 people. Yeah, what a wuss.
Makes me wonder: would the predator sucessfully kill Jason and take is shull, maybe also his mask, as a trophy or would Jason destroy the living shit out of the predator if the bastard tries to physically attack him (i.e. stabbing, impaling)?
