Notes

Krypto originally appeared in Earth-One continuity in Adventure Comics #210 by Otto Binder and Curt Swan. He was introduced in Earth-149 continuity in Superman #149 by Jerry Siegel and Curt Swan.
This version of Krypto, 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 event and later restored following the rebirth of the infinite Multiverse during the Dark Crisis of 2022–2023. Even though other versions of the character may have appeared, this information does not apply to those versions.
