Celtic’s reference is the Yautja from the Predator fictional universe Predator is a science fiction action horror anthology media franchise centered on the film series depicting humankind's encounters with a race of extraterrestrial trophy-seeking military personnel known as the "Predator". The Yautja, known colloquially as the Predators or Hunters, are an extraterrestrial species characterized by their hunting of other dangerous species for sport and honor, including humans. The Yautja are a sentient, humanoid race that breathes an atmosphere similar to that of Earth's but possess a level of technological advancement far in excess of anything available to humans. Yautja culture centers on the ritualistic hunting of other dangerous lifeforms, and this practice appears to be the foundation of their very society. Predators will travel huge distances even across entire galaxies in order to face opponents they consider a worthy challenge, and may also kidnap and transport prey across similar distances to bring such victims to a hunting ground of their choice. The Yautja have a Code of Honor during the hunt that it expects all members of the species to adhere to in pain of not being seen as a "true Yautja" and therefore subject to being destroyed. Therefore, most Yautja are molded around that code, being ruthless but honorable, with the exception of Bad Bloods. Aggression and arrogance seem to be innate in Hunters, especially young males. According to some reports, Yautja motivations for hunting are not just for sport, but rather for honor, with the species having developed a whole tribal culture around their status at the top of the food chain, as the ultimate Predator. Their code of honor dictates what makes a worthy adversary, and thus will make a Predator or clan more respected.
