Lobo was introduced as a regular character in Keith Giffen and Roger Slifer’s Green Lantern and Teen Titans spin-off Omega Men. At that time, he was a Velorpian whose entire race had been exterminated by Psions and was partnered with Bedlam, whom he later killed; his origin was later retconned.
After a well-received appearance in Justice League International, Lobo became a regular character in L.E.G.I.O.N. and its successor series R.E.B.E.L.S..
In 1990, he appeared in his four-issue own miniseries, Lobo: The Last Czarnian, plotted by Giffen, written by Alan Grant and with art by Simon Bisley, which changed his origin story: he became the last Czarnian after violently killing every other member of the species. That miniseries led to many subsequent miniseries and specials.
