Czarnia was a peaceful world, which had become a crime-free utopia that rivaled Krypton.
They had many social institutions just like Earth, such as day care, music concerts and mental asylums. Then one day a boy was delivered, and turned out to be so evil the nurse responsible went mad. He was named Lobo, meaning "one who devours your entrails and thoroughly enjoys it." At the age of 17, Lobo decided to wipe out the others in his race through a swarm of lethal scorpion-like creatures.
The planet later became the site of an assassination attempt on Lobo, which is detailed in the mini-series "Lobo Infanticide". Hundreds of his children, results of his womanizing, form a battalion to ambush him. Lobo, thinking he is taking parts in war games, patrols through various Czarnian canyons, even encountering his old house, which is still somewhat standing.
