Kryptonian

Kryptonians are an endangered near-human species hailing from the now-destroyed planet Krypton. They were one of the most scientificly and culturaly advanced race in the 28 known inhabitd galixies, if not the most aIn ancient times, a large tribe of Kryptonian imagrants traveled to Daxam and interbred with the species of that world, resulting in the Daxamites. Every twenty years, the Kryptonians were at war with their neighboring species, the Dheronians of Dheron. After the destruction of Krypton, Kryptonians were rendered extinct save one, Kal-El (Superman).

Powers & Abilities
Their cells have the ability to absorb and motabolize energy indowing them with amazing superhuman powers, as such, once outside their star system, they develope power determined by the age and frequency of each new sun's light and internal radiation. White stars and dwarf stars, blue stars, pulsar, quasars, and most notably yellow suns all are all known to give them different superhuman properties.

So far, Kryptonians have only absorbed the energy of yellow, blue, and red stars and have displayed many abilities including superhuman strength, speed, senses, intelligence, stamina, durability, leaping, dexterity, endurance, and healing, dilated perception, genetic sub-conscience (derived from their red sun), invulnerability, flight, x-ray vision, heat vision, telescopic/microscopic vision, and "Superman vision" (blue sun).

It should be noted that these powers don't manifest instantly and must evolve and develope as the Kryptonian grows older, however they have enough strength to bend steel even from infancy.
