Judomaster's secret identity was Hadley "Rip" Jagger, a sergeant in the United States Army during World War II. He rescued the daughter of a Pacific island chief and in return was taught the martial art of Judo. Jagger used his judo mastery to become a commando superhero, frequently operating solo behind enemy lines in the Pacific theater. He eventually gained a kid sidekick named Tiger. He is said to have been a member of the All-Star Squadron during the war, although no specific adventures are known at this time.
Judomaster was killed when he took part in the giant Battle of Metropolis, during which the supervillain Bane broke his back. Judomaster's death left an impact on his son, Thomas Jagger, an agent of Checkmate, who would later come into conflict with his father's killer, but resisted his desire to avenge Judomaster for honor and instead defeated Bane in a fight.
