Like many shapeshifters, a scorpion-man has strength and agility superior to that of a human being. Also, their eye color changes completely black with their pupils and irises not visible.
Like the kanima, the scorpion-man produces venom. Rows of venomous stingers will morph and protrude from their skin, along their limbs and down their spines. The stingers secrete a venom that inflicts an overwhelming, ever-lasting pain. This pain is non-lethal, and cannot be circumvented by narcotics. But the pain can be absorbed by a supernatural pain siphon.
