Predator: Predator is an alien species whose society revolves around a ritualistic hunting practice called being “blooded”. For a male predator to become “yautja”, or to be considered an adult and full participant in society they must kill a xenomorph, or the creature from the sci-fi horror classic Alien, Aliens, Alien 3 and then 3 unmentionable movies. They must get the kill using only blade weapons, shoulder fired plasma cannons are not permitted. Predators consider the Aliens “hard meat” because they are extremely hard to kill, and call humans “soft meat” because we are very easy for them (7 feet tall for males, females are larger. Skin that will stop most rounds below a .45, impossibly strong, advanced technology, and can move at somewhere between 40 and 50 mph. It is a close-combat culture, meaning they emphasize a mixed martial arts fighting style involving both projectile and bladed weaponry in addition to kicking, chopping, punching, blocking, grappling, etc.). Although humans are considered “softmeat” we are typically regarded as more dangerous than Alien drones because we are more intelligent and capable of innovation, deceit, amd tactical behavior. Predators regard Alien queens as the most dangerous. There has been one human who has earned the right to hunt with the predators. A Japanese woman by the name of Machiko Noguchi, she has appeared in numerous comics, the first being Alien vs. Predator, and three books, Aliens vs. Predator: Prey and its sequel, Aliens vs. Predator: Hunter’s Planet, and Aliens vs. Predator: War. Predator’s must wear masks on earth because the oxygen content is too high. In Predator II, starring Danny Glover, Gary Busey, and Bill Paxton, the Predator, after losing it’s mask, is seen using a rebreathing apparatus to combat the effects of hyperoxygenation.
I’ll have to do Boba Fett later, I don’t know the canon for Iron Man and Robocop, but they’re badasses too.
