Rip Hunter is a DC Comics character who first appeared in Showcase #20 (May 1959). Following three more appearances in Showcase (#21, 25, 26), Rip Hunter was given his own series, which ran for 29 issues (1961-65). He later starred in the eight-issue Time Masters series (1990), written by Bob Wayne and Lewis Shiner. He was created by Jack Miller and Ruben Moreira.

The Challengers of the Unknown were a quartet of science fiction adventurers created by Jack Kirby. They debuted in 1957, and their commercial success spawned two other science fiction characters: Cave Carson and Rip Hunter. Hunter was the more successful of the two, with art in his early appearances by Joe Kubert, Mike Sekowsky, and Nick Cardy. Hunter was the leader of a gang of time travelers who were featured in brisk and historically accurate adventures in various eras. DC editor Jack Schiff reported that he and writer Jack Miller had "lots of fun" creating the comics.

Rip Hunter has had a number of revisions within the fictional DC Universe. Those changes are generally connected to larger events and story lines. The writing and editorial staff often use a narrative device within the comics known as a crisis event to explain dramatic changes to the appearance or personality of characters. Rip Hunter has undergone a number of different developments within this fictional universe.

In his original incarnation, Rip Hunter is portrayed as an ordinary man who uses his self-invented Time-Sphere to travel through time. Aided by his friend Jeff Smith, girlfriend Bonnie Baxter, and Bonnie's kid brother Corky, they have adventures in time. Those stories were told in the self-titled series Rip Hunter...Time Master which ran for 29 issues between 1961 - 1965.

Rip Hunter has not been a contender in any CBUB matches.
