Korg has thick, rocky skin similar to the Thing's save it is more dense. The skin is very hard to crack and gives Korg super strength. As he can not be broken, Korg can be used as a battering ram.

Korg possesses various superhuman attributes common to all Kronans.

Superhuman Strength: Korg is superhumanly strong, though the full limits of his strength aren't known. However, Korg is at least as strong as the average member of his race, which means that he can lift at least 100 tons.

Superhuman Stamina: Korg's highly advanced musculature produces considerably less fatigue toxins during physical activity than the musculature of humans. While the full extent of his physical stamina isn't known, he can exert himself physically at peak capacity for at least 24 hours before the build up of fatigue toxins in his blood begins to impair him.

Superhuman Durability: Like other Kronans Korg possesses a dense rocky hide comparable to the Thing's that renders his body highly resistant to physical injury. Korg can withstand great impact forces, falls from great heights, exposure to temperature and pressure extremes, and powerful energy blasts without sustaining injury.
