Predators are pussys. They got killed by humans in hand to hand combat multiple times. If Danny Glover and Adrien Brody can kill Predators in hand to hand combat then a Xenomorph would definitely make short work out of a Predator.
The AvP movies are NOT canon to those idiotic Predator fanboys who think Predators are better.
AvP writers had to nerf the Aliens to make the fight fair for the Predators.
Neither of them are that hard to kill. Predators more so than Aliens because of their technology and armor. Aliens can die to bullets and have no natural protection, especially out in the open. They would obviously have an advantage in CQC scenarios, especially in narrow places, which all the "canon" Alien movies favor them in, and exactly for the reason I mentioned above: they'd get destroyed out in the open.
Humans can die. Aliens can die. Predators can die. Each can kill one another.
Clone Ripley literally ripped an Alien in half with her bare hands. Judge Dredd killed Aliens. So did Batman. So did Predators. Matter of fact, in this movie, I watched one Predator chalk up a massive body count against Aliens. I watched a Predator dominate a host of Aliens in fisticuffs melee macabre, BIG time. Canon? Hah. What Alien universe is really canon? And what universe that is canon do both species really live in together? They are separate creatures from different fictional IPs.
Besides, Humans own everything, really. We did, after all, CREATE all of it. Our minds own these fictional machinations. Just like we own E.T. and ALF; we own Aliens, Predators, and Prometheusii.
Most of the things you said weren't even canon. They were all from comics and expanded universes in which are fan fiction.
Clone Ripley never ripped an Alien in half. I don't remember a single scene in Alien Resurrection that showed that.
And yes, Aliens do have natural protection. They have exoskeletons. If you watch the film Aliens, Gorman was shooting an Alien in the vent with his pistol and you could see bullets bouncing off the Alien's head. Colonial marines were able to kill Aliens easily because they had to use high caliber armor piercing rounds to penetrate the Aliens' exoskeletons. Their pulse rifles were obviously rip a Predator to pieces in seconds since Predators got killed by humans in HAND TO HAND COMBAT multiple times as they were shown in Predator 2 and Predators.
