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 colour, body hair, and so forth). One of Kro's favourite ploys is to pass himself off among ordinary humanity as a demon by fashioning horns on his head.

However, Kro's shape-changing powers are limited. He cannot alter the shape of his skeleton in more than minor ways. Moreover, he cannot eliminate any of his mass while transforming; he can only redistribute his 320 pounds of weight. Hence, he ususally only uses his shape-changing pwer to alter his facial features. He can mentally mold the shape of his skull somewhat.

Kro has about three times the physical endurance of an ordinary human athlete. His heart is not located in the same place as an ordinary human being's; its true location is unrevealed.
