The Velorpians were a violent and greedy race, and whenever one was killed, they would generate a hundred duplicates.
This led to overpopulation and fighting over precious resources.
Fearing the Velorpians' violent nature could wreak havoc upon the universe, the Psions introduced a virus to render them all sterile. The population decreased over time, with Lobo being the only survivor. He somehow retained his regenerating powers.
Powers and Abilities
- Bio-Fission: originally, when a Velorpian died, this would generate 100 duplicates of himself. This ability was eliminated by the Psions.
- Photokinesis: Velorpians could generate non-blinding light with their hands.
- Superhuman Strength: Enough to spread the brain of a victim across the room with just a flick. 
- Superhuman Reflexes
- Enhanced Sense of Smell
- After the Crisis on Infinite Earths, the Velorpians were erased from existence and replaced by the Czarnian species. The Velorpians' bio-fission ability and violent nature became traits unique to Lobo alone; most Czarnians were peaceful and stayed dead when killed. Which they all were. By Lobo.
