Judomaster is the name given to three fictional superhero published by DC Comics. The first Judomaster debuted in Special War Series #4 (November 1965) published by Charlton Comics, and was created by Joe Gill and Frank McLaughlin.

Judomaster's secret identity was Hadley "Rip" Jagger, a sergeant in World War II in the United States Army. He rescued the daughter of a Pacific island chief and in return was taught the martial art of judo. He had a kid sidekick named Tiger. In the Nightshade backup series in Captain Atom, an adult Tiger was Nightshade's martial arts instructor.

Judomaster's title lasted from #89 to #98, from June, 1966 to December, 1967. (It was a retitling of Gunmaster, which was itself a retitling of Six-Gun Heroes).

Along with most Charlton super hero characters, the rights to Judomaster were sold to DC Comics. In post-Crisis continuity, Judomaster was said to be a member of the All-Star Squadron, DC's team of superheroes during World War II, although he has never appeared in an actual published story as a member of said team. His kid sidekick, Tiger, would later become the villain Avatar in the L.A.W. mini-series published by DC Comics, which re-teamed the Charlton characters that had been acquired by DC. In the same series it is shown Judomaster has lived for some time in the fictional city of Nanda Parbat. As time passes in a different manner there, Judomaster has retained a younger form. Since the mini-series, Judomaster has only appeared a few times.

Judomaster (Sonia Sato) has not been a contender in any CBUB matches.
