Known Superhuman Powers: The Thing possesses superhuman strength, endurance, and durability. The mutagenic, specific-frequency cosmic ray bombardment caused his musculature, bone structure, internal organ composition, soft tissue structure, and skin to greatly increase in toughness and density. The Thing can exert himself at high levels for about an hour before the build-up of fatigue poisons in his blood impairs his strength. His reflexes have remained at their above average human levels despite his greater mass. The Thing's lungs are of greater volume and efficiency than a normal man's, enabling him to hold his breath underwater for up to nine minutes, The Thing's five senses can withstand greater amounts of sensory stimuli than he could when he was a normal human being, with no reduced sensitivity.
