Kryptonian

Kryptonians are a fictional extraterrestrial race within the DC Comics universe that originated on the planet Krypton. The term originated from the stories of DC Comics superhero, Superman. The stories also use "Kryptonian" as an adjective to refer to anything created by or associated with the planet itself or the cultures that existed on it. Kryptonians are indistinguishable from humans in terms of their appearance, but in terms of their physiology and genetics they are vastly different.
