Like full blooded Rock Trolls, the various tissues of Roughouse's body have much greater density than those of ordinary humans (contributing somewhat to Roughouse's great strength and size). As a result, Roughouse's body is highly resistant to conventional injury. Roughouse's body can withstand temperature extremes, puncture wounds, impact trauma, and high caliber machine gun shells without being injured. Even though Roughouse can be injured, the force or weaponry required to do so would have to be considerably more powerful than most conventional materials.
