Choku were a species of Reptavians that were indigenous to the Yavin 4 planet. These creatures walked on four legs and were notable for their vibrantly colored coats of fur. Males displayed brown and white fur, while females had black and white fur. Functioning as powerful carnivores and lethal predators, they lived and hunted collaboratively in packs.
The Choku made an appearance in Star Wars Galaxies, a video game from 2003 that was a massively multiplayer online roleplaying game. It was created by Sony and distributed by LucasArts before its shutdown on December 15, 2011.
