History of character is unknown.
- This version of Zat-El (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.
- 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.
