Jur-Ll

A Kandorian crime lord who battles the team of Nightwing and Flamebird and is in actuality a counterpart of Jor-El whose "Krypton" is believed to never have exploded. Jur-Ll was "his Krypton's" greatest scientist, and was considered by the authorities to be its greatest threat. In his hands, the simplest of materials became a master weapon, which he used to build a few simple men into criminal empire to rule "Krypton." He would indeed have ruled his planet had his chief lieutenant not betrayed him and turned him over to the authorities. As punishment for his crimes, he is condemned to permanent exile within his own version of the "Phantom Zone."

Jur-Ll would have remained there indefinitely had he not escaped through a dimensional rift that led him to the Kandor of the Earth-1 universe. However, he seemingly trades one prison for another, as he arrives in Kandor on the very day that Brainiac steals the city for his collection.

Jur-Ll does not let this deter him, as he sets about building a new criminal empire with the ultimate goal of escaping Kandor. Years later, he battles the team of Nightwing and Flamebird, but is defeated, and apparently killed, when Flamebird tosses him into the devices that he is attempting to use to destroy the bottled city and re-enlarge himself (SF No. 194/2, Mar/Apr 1979: "Showdown").

(Note: It might be conjectured that Jur-Ll's home universe is that of Earth-3, where the roles are reversed [for example, President John Wilkes Booth was assassinated by actor Abraham Lincoln]. However, since Jur-Ll died before being apprehended by Nightwing and Flamebird, this theory can neither be proven nor disproven.)
