History of character has not yet been written.

  • This version of Zat-El (Earth-One), including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
  • Superboy presumes kinship with Zat-El based on his surname, but he was not mentioned in the annals of the El family, and lived long before its recorded history.
