- This version of Paul Kirk, 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.
- This Paul Kirk starred in a feature called "Paul Kirk, Manhunter," but that was just the name of the feature. He was not called "Manhunter" as a nickname, and he had no association with the Manhunter Cult.
- "Paul Kirk, Manhunter" was replaced in Adventure Comics by a superhero feature called "Manhunter", starring a different Paul Kirk who was secretly the superhero Manhunter.
