Your coming across as stubborn to your fanboy opinion that aliens are unstoppable and can rip anything apart.
I know preds arent unstoppable and insanely strong, so i give a reasonable statement or opinion when comparing, and i dont just automatically assume the pred would come out on top.
I know that a pred could take an alien down in hand to hand combat, no doubt about it, but im not saying there isnt a chance for the alien to win. I wont say the pred can take on numerous amounts of aliens and come out unscathed either.
And a predator is VERY much more durable than a human, and i agree so is an alien.
A predator, as seen in both movies, could take an amputated limb, multple(more than 5?) rifle(or shotgun) shots to the chest, and still leap incredible heights and land like it was nothing. Im thinking its mainly muscle that absorbed those hits, but still, that alot of damn muscle. If a human were to go under that type of damage he'd probably die of blood loss or go into shock or just die.
Also, a predator obviously has the strength to rib bone and tissue apart with his bare hands. How do you think he gets the skulls? Rips them straight out of the back, spine and all, with one hand on the skull and the other on the shoulder. Breaking a limb on an enemy would be nothing but a flick of the wrist for such a strong creature. but was we have ever seen hand to hand against a human was slaps, and punches, no real holding moves that could break bone.
The original idea though was a no brainer, as of course a chestburster is in a way stronger than a BABY Predator, as they probably havent even developed the type of body to put that much pressure on anything by 5 days old. It was one of those "whats stronger, Grenade or paper ball" type of questions.
But just because a chestburster is stronger than a baby predator means in no way that the fully grown alien is inarguably stronger than a full grown, or even teenage yautja. Given the facts above and throughout this whole topic.
