Kro also possesses the power of physical malleability, which is atypical for a Deviant. At will he can cause most of the tissue of his body to become pliant, enabling him to shape it mentally like putty into different configurations. Once the tissue is set in an altered form, Kro has only to stop concentrating and his body will retain that shape until such time as he concentrates upon changing it again. This ability enables him to disguise himself and take the appearance of others (with cosmetic help for skin color, body hair, and so forth). One of Kro's favorite ploys is to pass himself off among ordinary humanity as a demon by fashioning horns on his head.
