Jur-Ll

A Kandorian crime lord who battled the team of Nightwing and Flamebird and was 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 could become a master weapon, which he used to build a few simple men into criminal empire to rule Krypton. He would indeed have ruled his Krypton had his chief lieutenant not betrayed him and turned him over to the authorities. As punishment for his crimes, he was 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 traded one prison for another, as he arrived in Kandor on the very day that Brainiac stole and shrank the city for his collection.

Jur-Ll did not let this deter him, as he set about building a new criminal empire with the ultimate goal of escaping Kandor. Years later, he battled the team of Nightwing and Flamebird, but was defeated, and apparently killed, when Flamebird tossed him into the devices that he was attempting to use to destroy the bottled city and re-enlarge himself.

(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 assasinated by actor Abraham Lincoln]. However, since Jur-Ll died before being apprehended by Nightwing and Flamebird, this theory can neither be proven nor disproven.)
