Background Information

In the parallel-universe of Earth-1A, shortly before the destruction of Krypton, a team of unnamed scientists (presumably Jax-Ur, etal) were sent to the Phantom Zone when they attempted to strand the Science Council in outer space. His crime led to a new law being developed that would make space travel illegal.[1]

In the parallel-universe of Earth-One, the mad-scientist Jax-Ur, was sentenced to the Phantom Zone fro destroying an inhabited Kryptonian Moon during an experiment.[2]


A council-member mentions how Jax-Ur and his group of scientists tried to exile the Science Council in outer space.[3]


  • Jax-Ur made his first appearance in Adventure Comics, #289 (October 1961).
  • He was created by Otto Binder and George Papp.
