Byrnians are a humanoid species hailing from an unknown planet.


Two Byrnians were charged and imprisoned in Fort Rozz, inside cages made of intertron. However, Fort Rozz eventually crashed on Earth, allowing them to escape.

Physical appearance

Despite hailing from another world, Byrnians are indistinguishable from humans. Apparently, all of them are redheads.

Powers and abilities


  • Solar energy absorption[1]
    • Shapeshifting: Byrnians usually maintain a humanoid appearance. However, once charged by the energy spectrum of a yellow sun, Byrnians involuntarily transform into a monstrous creature.
      • Super strength: In their monstrous form, Byrnians are capable of great feats of strength, and only grow stronger the more they fight.
      • Invulnerability: Byrnians are resistant to forms of various attacks or damage that would kill or severely injure a normal human.
