I have noticed that as portrayed in the films, Predators seem to be immune to electricity. This is often shown alot in Predator, Predator 2 and of course perhaps Alien vs Predator. I believe that the Predators ARE immune to electricity and the scene in Predator 2-- where the Predator raises his combi-staff up into the sky, only to be struck by a bolt of lightning and not be harmed by it all, somewhat supports this.
I believe that electricity would do nothing against a Predator...
However, what is everyone's opinion on this?
