A Xenfex is a medium sized reptilian creature that is usually found on the planet Zarbon. They are vicious creatures that can become very territorial at times. They lay eggs to breed and are carnivores, mostly being the best predators on Zarbon. But there are other creatures that are a better predator then the Xenfex, making it not always the best hunter on the planet. So far, they have only appeared in Guardians of the Republic.
The Xenfex is strikingly similar to a Velociraptor, and that's because it is the official Lego raptor.The Xenfex was originally planned to appear later in the game, but it never did. It may, however, return in Potato's next game.
