History of character has not yet been written.
- Super-Leaping: Frog Man is a atavist, an evolutionary throwback with traits that were present in humanity's ancestors but are gone now. He is a throwback to the common ancestor of mammals and amphibians (the early tetrapods), and therefore he has frog-like features. He has powerful legs, which he uses for kicking and jumping. It is unknown if his other frog traits (green spotted skin, rotund body, wide mouth, etc.) provide him with other powers.
- Frog Man is a pastiche of the Marvel Comics character Toad.
- This version of Frog Man, 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.
