Young Zarl Vorne was rocketed from Atlantis on Earth by his scientist father. He landed on an asteroid named Juno, and was frozen in suspended animation for 10,000 years before being revived by natives.

Gaining superpowers similar to Superboy, he became a crimefighter.

One day, Superboy arrived on the asteroid, but due to his proximity, caused Power-Boy to weaken, forcing him to leave.[1]

  • This character was one of many Superboy/Superman analogues the Kal-El from Earth-One encountered during his travels.
  • See also Power Boys and Hyper Men by John Wells.
  • This version of Zarl Vorne (Earth-One), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
