Kryptonians are an endangered humanoid species that were native to the now-destroyed planet Krypton.


Kryptonians are outwardly indistinguishable from humans; however, due to their more complex genetics, they possess super-powers once exposed to radiation from a yellow sun. These powers range from superhuman strength to flight.[1]

Kryptonian DNA is difficult to fully synthesize, hence Cadmus created the clones Match and Superboy with gaps in their genomes, which in the latter's case were filled in with human DNA (Lex Luthor's).[2]
