The Yautja Codex is an extensive and complete language and code of honor built for the fictional Yautja species within the Predator movie universe. Dan Trachtenberg, director of Prey, Predator: Killer of Killers and Predator: Badlands hired linguist Paul Frommer, the same guy responsible for developing the Na’vi language for James Cameron's Avatar films to create the new Predator language - the Yautja Codex. This article will contain information and translations for that language as new details become available.


The first instance of the Yautja Codex being referenced in a Predator film was with 2025's animated anthology film Predator: Killer of Killers.
This language and codex will be further expanded upon in Predator: Badlands, as Dan Trachtenberg explained in a recent interview:

We, insanely, decided to really treat that properly and worked with, we reached out to the guy who does the Na’vi language [in Avatar], who was very occupied, and recommended his mentee. We did it the way that, for The Lord of the Rings, you would do Elvish, for Game of Thrones, you do Dothraki. Except for those, there’s more precedent, for us, there’s very little. As we discovered, with him being a language expert, all the stuff, and frankly, actually working with [Predator special effects artist] Alec Gillis, all the stuff that you’ve seen in other Predator movies is complete garbage. There’s no sense of it. People from the Internet have tried to make sense of it, but none of it was made with intention.
So we decided to make it with intention and we completely developed the language, so everything they’re speaking has actual rules and structure and all that stuff. And written as well as verbal.
