Kryptonians (Race) (DC Comics)

Résultat de recherche d'images pour "Kryptonians dc logo"
Kryptonians are a fictional Humanoid extraterrestrial race of the DC Comics universe who hail from 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 culture that existed on it.
Members of the dominant species of the planet Krypton are indistinguishable from Humans in terms of their physical appearance, mentality, and internal biology; though their genetics are much more complex. The cellular structure of Kryptonians allows for solar energy to be absorbed at extremely high levels. On the planet Krypton, whose sun was a red supergiant with a relatively low energy output, their natural abilities were essentially the same as Humans. When exposed to a yellow star like Earth's Sun, which is much smaller than their own sun and with a vastly higher energy output, their bodies are able to absorb and process so much energy that it eventually manifests as vast superhuman powers (such as flight, superhuman strength, x-ray vision, superhuman speed, invulnerability, heat vision, and superhuman hearing).
Nearly all Kryptonians were killed when the planet exploded shortly after the infant Kal-El was sent to Earth. In some continuities, he is the planet's only survivor.

Kryptonians are an alien humanoid race of being who originate on the planet Krypton. Kryptonians are basically humans in their structure and appearance. But their biology is far more advanced than that of Earth based humans where they are able to utilize energy in their body with far more direct and elaborate manners than Earth based humans do.
Various dimensional Kryptonians have developed superpowers in regards to Earth based humans that vary drastically in comparison to their various native dimensions. Super speed, heat vision, x-ray vision, and super breath are among many Kryptonian superpowers.


Kryptonians are a highly technologically advanced people. Their technology seems to be based on self-grown crystals which made up the vast majority of their planet's surface. Vast amounts of data and information could be stored on relatively small crystals. The Fortress of Solitude is a recreation of Krypton's surface, and also serves as a storehouse for all the knowledge obtained by the Kryptonian race from the 28 known galaxies.
Each Kryptonian family, or what is called a "House," is represented by a crest or symbol, often worn by the head of the house. The House of El, for example, is represented by an "S"-like shape. Coincidently, Superman wears this same symbol on his costume that serves for dual meanings: his Kryptonian heritage and the "S" for Superman.


When Krypton was destroyed, it was thought that the entire kryptonian race was destroyed. This was largely disproven by the survival of Kal-El, who was sent off Krypton to Earth by their father right before their source worlds were destroyed. Kal-El grew up on Earth aware of his Kryptonian heritage. 
Kal-El and was NOT the only survivor of his home world. His cousin Kara would also be sent from Krypton to Earth. Supergirl, cousin of Superman, also survived Krypton's destruction and made home on Earth. The capital of Krypton, Kandor, was also spared from destruction as it was shrunken by Brainiac.
