Originally a centaur named Biron that was accidentally transformed into a full horse by Circe. In an attempt to undo the spell of Circe; Biron was given powers of strength, flight, invulnerability, telepathy, and telekinesis by the gods. However, Circe angrily trapped Biron inside a comet and launched him into Space, where he was inadvertently freed by Supergirl. She named him Comet and kept him as her horse. He can turn into a human when a comet flies across the sky.
