Super Strength

Super Strength is the ability to perform massive feats of strength that appear to exceed or surpass the average levels of physical durability. It is a common ability among the alien species of Kryptonians when under the rays of a yellow sun.

Super Strength in Kryptonians
Unlike a great majority of Kryptonian powers and abilities that manifest because of unknown inner development, super strength appears to manifest early on, and much like their stamina, speed, invulnerability, and longevity, this ability seems to become immediately inherent after they get exposed to an environment under a yellow sun. Kryptonians are among the strongest beings in the universe. Direct sunlight exposure greatly aplifies and increases a Kryptonian's strength capability. Atmospheric density also carries great significance in the performance of incredibly enhanced strength.
