A powerful, humanoid monster breed that first appears in Monster Farm DS. It seems that combinations with Xenon as the sub-breed release the goodness within the new sub-species, and thus they are usually snow-white incarnations. Though not much is known about them at this point, Xenons seem to be the antithesis of the evil Abyss species. They have a connection with the cosmos, while the Abyss have a connection to chaos.

The main villain of Monster Rancher 4 is a skeletal monster called Xevion which could be an early version of this species. He has several forms, one that involves battle armor. This adds to the idea that Xenons can transform into a more armored form, or mode.
