In the comic that relationship took a large chunk of the comic to build up. Broken Tusk being saved by the colonists, and then BT saving the colonists from one of his rogue students. Plus the whole "hunt" going way out of control.
Even then, though, i'm not entirely sure what possessed the writers of the original AVP to turn the Predator's into anti-heroes. I mean, yeah, they're on this side of Jason Voorhees in terms of how well they can relate to us, but that doesn't mean they would stoop to siding with us. They blow themselves up when they lose.
With all that sad, I would not mind if they actually adapted the comic. I like the original comic a lot. As far as Alien and Predator comics go it's right near the top.
I wouldn't mind one based on "Chained to Life and Death" either. Greatly expanded, of course. The idea of an Elder Predator setting up an attempted suicide hunt would make for a great setup.
