Even with invisibility the Predator isn't hiding from Sabretooth. If he has real good aim with the blade he could take off some Sabrelimbs. I still think Sabretooth finds the Predator and guts him, and since the Predator doesn't have any healing factor Sabretooth takes this.
So for the sake of the argument, Franklin will not have any premonitions about Zoom coming because that counts as prep time? But if it happens, Franklin would see it before it did. But he's not allowed to see it becasue that is prep time.
This is starting to become a time paradox here.
I think Zoom is pretty cool, just trying to come up with someone to beat him from Marvel Earth.
