Kryptonian

Kryptonians are an endangered near-human species hailing from the now-destroyed planet Krypton. 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 acquire new abilities determined by the frequency of each new sun's light and internal radiation. White stars and dwarf stars, blue stars, and yellow suns all give them different properties. Pulsars and quasars give power beyond imagining. Kal-El has only been empowered by a yellow sun.

It should be noted that their 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. By age 20, they possess superhuman strength, speed, durability, memory, healing, and senses, x-ray vision, heat vision, telescopic/microscopic vision, and flight.
