Manhunter is the name of several fictional characters appearing in comic books published by DC Comics and Quality Comics.
Paul Kirk, Rick Nelson, Paul Kirk
"Paul Kirk, Manhunter" was a crime series that ran in Adventure Comics #58–72 (Jan. 1941 – March 1942). In this original incarnation, Kirk was a non-costumed investigator who helped police solve crimes. The word "manhunter" in the title was merely an epithet describing Kirk's role and was not a name, nickname, or alias used by Kirk in the stories.
The final issue of Adventure Comics to feature a "Paul Kirk, Manhunter" story was #72. The following issue replaced it with a new Manhunter, by Joe Simon and Jack Kirby. This was Rick Nelson, a former big game hunter turned superhero. After a few issues, the name Rick Nelson was replaced by the name Paul Kirk, despite being a completely different character. The Simon/Kirby team left the feature after #80 (November 1942), though this Manhunter appeared in Adventure Comics until #92 in June 1944. This version was later brought back by Archie Goodwin in the 1970s.
