crystalsapien

An alien species appearing in Ben 10, first appearing in Ben 10: Alien Force. Unlike other alien races, there is only one natural member of this species, Sugilite, who serves as the guardian of Petropia and its Petrosapien citizens. The Omnitrix's sample of a Crystalsapien, Chromastone, was created based on Sugilite's DNA and served as a back-up guardian after Sugilite was destroyed along with Petropia.
