The Predators have highly advanced Super Weapons. The metal they use is nothing like the metal from Earth, Theyre not easily destroyed acidicly. Remember, they created the aliens. Of course they will have things to protect against them. The Fact that Predators dont go in fulley armed, is because they dont work like you an me. They have base intelligence, But they work completely different in that of a Human with Animal instincts. They are purely and solely a race BUILT off Hunting. You cant give them a video game, and teach them how to play it. They dotn work at all like that. The Honor of the hunt Code 1, Is never attack weak Prey. Hence, Unarmed Men, or Ill people or creatures. The Code 2 is never have the supreme Advantage, that isnt hunting. It really says alot about what the Deer Hunters of today call sport. Sitting in a car wearing camoflauge shooting animals, and saying that was sure hard. Notice how the predator didnt just kill everything unless it was in its way, or bothersome.
These were three Predators, trying to proove themselves worthy. The Earth is a cattle planet, lets send them down and see how well they do defending and stopping this menace of a planet we were once god of. Two of the Predators were easily dispatched, because of minor skill, and stupidity, they were destroyed EASILY by a basic black alien. The Third one didnt take that. He ovbiously was well equipped, educated a bit more, and more conscious about the world around him.
Predators are Built on skill Gaining. To the point where they will take off all armors and weapons, and use just a knife, if another species is facing them with a knife and nothing on, the Predator will get down in and do the same. To the Victor goes the Death, and Skill knowing you defeated an equal enemy, rather than vaporizing it with no skill involved.
As for that Alien Emerging from the Predator question mentioned earlier. THE PREDATORS Knew PRECISELY That a Alien was going to come out of the Predator, thats why they took HIS DEAD body in on a stretcher, and set it on there honor table.
One problem. It wasnt an Alien.
It was a Predalien.
For this reason alone, they didnt neutralize the already dead body to rid it of the body.
A Predalien is a cross of Alien and Predator. When an Alien lays eggs in a predator, duh!
The Predalien is 20X stronger than the Alien, and can use all the gadgets and hunting expertise as the Predator. Not only does it have Acid Blood, but it Also sees in a cross between Predator, And alien. Making its sight almost perfect. A Predalien has a elongated head, that looks like predator, but is more gray and the Mandiles are shaped more like sticking out. The Mouth killer piece inside the mouth of the Predalien looks like the Predator Mandibles too.
The Predalien is normally about 9 feet tall, and has a long gray spiney spiked tail. It has a alien type torso, but More of a thick middle like the Predator.
There is also a Praetorion. Its the Queen of the Predaliens.
Pick up Alien VS Predator 2, The PC game. It really expands on the movie big time.
