Xon-Ur was created on an alternate version of Krypton that was formed within the Phantom Zone and served as part of the machinations of Brainiac 13. Through a combination of B13 Technology and a Kryptonian Birthing Matrix, this alternate Krypton was formed and modelled after the descriptions in Jor-El's diary. This was not an accurate representation of Krypton before its destruction but rather modelled after a favourite golden age that occured thousands of years ago. The reason for its creation was it was to serve as part of a carefully modelled trap by Brainiac with the intention of entrapping Superman within it. By providing such a temptation of a living Krypton inside the Phantom, Brainiac wanted Superman to journey to this planet where he would isolate him within it forever. Once that was done, a catastrophic series of events would occur that would fulfill the artificial worlds programming and it would destroy itself thus killing Superman.

Within this world, a Kryptonian known as Xon-Ur arose and he became a devoted yet fanatical follower of the Sun God Rao. When this worlds alternate version of Jor-El created the Kryptonian Incubation Chambers, Xon-Ur formed an army of zealots called theHoly Order of Rao that was based at Mt. Mundru who opposed the technological blasphemy that inflicted their world and sought to purge it of such an influence. He later assaulted Jor-El's laboratory and stole the Incubation Chamber whereupon he cloned his followers to make a mighty legion to complete this task. Xon-Ur was also in possession of a mighty artifact called the Heart of Krypton which he felt was a vital link to Rao and the key to saving his world.

Powers and Abilities

As a Kryptonian, it's assumed Xon-Ur has the standard abilities (enhanced strength, speed heat vision, super-hearing, enhanced vision, x-ray vision, flight and etc) upon absorbing yellow solar energy. However, he never display them in his appearences for he is not exposed once to yellow sun rays.

Despite this, he is shown to be very strong physically, being able to keep up (and eventually overpower) Superman and Jor-El, in their weakened states under the Red Sun.

His weapons of choice are dual flame swords, that are also used by the members of his order. They radiate red solar energy that weakens even further yellow-energy battered Kryptonians.
