Knodar is a citizen of the year 2447 AD in a possible future where crime is a thing of the past and all society's needs are met by machines. Knodar rebelled against this sterile system by becoming the 'Last Criminal', but was soon caught, and placed in a cell in a customized prison uniform. He escaped and time traveled back to 1947, where he embarked on a crime spree which was stopped by the Green Lantern before being returned home and to jail by a man from his own time named Dalmyr. He nonetheless escaped and tangled with the Green Lantern again at least twice more before the end of the 1940s, and later resurfaced during the Crisis on Infinite Earths, whereupon he was challenged by the Star Spangled Kid and private detective Jonni Thunder. He was later seen at Roulette's club for super villains.
