series – in March 1937. He debuted a year before Superman's first appearance, and two years before Batman would become the title's lead feature. The character's adventures continued as Batman was introduced in issue #27, continuing as a supporting feature until Detective Comics #152 (October 1949). According to Jess Nevins' Encyclopedia of Golden Age Superheroes, "He fights ordinary criminals, Yellow Perils, stage magicians, the Human Fly, creatures from the year Two Billion, the Man-Beast, and on at least one occasion space aliens." Slam was replaced in Detective #153 by Roy Raymond, TV Detective. Bradley would not make another significant appearance for over 32 years and his sidekick Shorty Morgan disappeared completely. The character was originally operating out of Cleveland, then later in New York City, Slam and his sidekick "Shorty" Morgan often had humorous, fight-filled adventures, often going undercover in various professions to catch their man. Though most stories had a mystery element, "Slam" was more likely to solve them with his fists than his brains. Revival The character reappeared in Detective Comics #500 (March 1981). In a story titled "The Too Many Cooks... Caper!", an aging Bradley joined other DC detectives, such as Jason Bard, Pow-Wow Smith, Roy Raymond, the Human Target, and Mysto, Magician Detective in solving the murder of a fellow retiring detective. The character returned again in Detective Comics #572 (the 50th anniversary issue), teaming up with detectives Batman, Robin, Elongated Man, and Sherlock Holmes. He appeared in the Superman titles in the 1990s, working for the Metropolis Police Department. However, this incarnation of the character was short-lived. When an older Slam Bradley later appeared in Detective Comics, it was explained that the Metropolis character was Slam Bradley, Jr. In 2001, writer Ed Brubaker and artist Darwyn Cooke revived the character in the four-part serial "Trail of the Catwoman" in Detective Comics #759-762. In this story, he investigates the death of Selina Kyle and in the process runs afoul of the Batman. This incarnation of the character is a former police officer in his late 50s who has always worked in Gotham City (contradicting the previous Cleveland, New York, and Metropolis settings). Bradley then became a supporting cast member in the Catwoman ongoing series. He reveals that he has a son, Sam Bradley Jr., on the Gotham City Police Department. Sam Jr. and Selina Kyle engaged in a romantic relationship that produced a child, Helena Kyle.
