The Yautja, more popularly known as the Predators, are an alien race and the main antagonists of the Predator film series. They also appear as anti-heroes in the Aliens vs. Predator franchise. The Yautja species consists of mostly male Predators - the Predator females are a rare occurrence, and there are only a few known ones. The Predators as a dangerous race are great hunters, with trophies from many species across the galaxy. They are attracted to war zones, as those hunted there would make for the more difficult trophies to acquire, as well as the ones with the most honor attached. Trophies can consist of skins or skulls with the spinal column still attached. They often wear masks, and their faces resemble large crustaceans. Their equipment includes invisibility technology, as well as an array of weapons, including powerful shoulder cannons. They also wear small but powerful bombs on their wrists in case of defeat. Despite the Predators' ruthless and aggressive behavior when they hunt their prey down, they all have a great sense of honor and fight with it. They never kill innocent, sick, pregnant, or unarmed people, and they show great respect towards those who have defeated their own kind.
