Czarnians were a race of humanoids from the planet Czarnia.
History
Czarnians were a peaceful race who had established a crime-free utopia that rivaled Krypton. This was all destroyed by one of their own, Lobo, who unleashed a global genocide in the form of a bio-engineered flying scorpion-like creature with a lethal sting. He succeeded in terminating every member of his race on Czarnia, then abandoned his home world for a life as a bounty hunter.
