The Xenexians are the humanoid natives of the planet Xenex. If Capt. Mackenzie Calhoun is any indication, Xenexians mostly resemble humans, but with eyes with irises that are a startling purple. Also, many Xenexians are apparently able to regulate their body temperature to a certain degree. Also some Xenexians such as Xyon of Calhoun have demonstrated low level psionic abilities, however since no other Xenexians with these abilities are ever referred to, it is likely the ability is either unique or rare. Xenexian names often use gutturals that offworlders find difficult to pronounce.
