The Krex are a hardy reptilian species with a knack for survival. Despite their fearsome appearance, the Krex are most widely known as explorers, pioneers, and colonists of hazardous and far-flung worlds, where their natural regenerative properties and tough skin are of great benefit. Still, it's not uncommon to find hardened Krex putting their abilities to work in other dangerous professions.

Interestingly, the Krex homeworld of Rokirex does not appear to be their actual planet of origin; the ancient mythology of the Krex refers to their ancestors exclusively as "travelers", and no examples of similar species can be found anywhere in the Rokirex archaeological record. This has led some biologists to theorize that they are actually descendants of long-lost Chistori colonists who gradually developed into a distinct genetic line.
