Wrestler Brett Carson obtained super strength in the process of fighting the paralysis of polio (and refusing to accept the doctors' prognosis of permanent paralysis) and used it to fight crime. He was assisted by sidekicks Kid Muscles and Miss Muscles, who appeared in backup stories. With a superhero costume consisting of red-and-black wrestling tights with a yellow "M" insignia, Carson is one of few who did not wear a mask and whose identity is publicly known. An additional character, Steeplejack, starred in a backup feature in the second issue.
The comic book Mr. Muscles ran two issues numbered #22–23 (March and August 1956), the series having taken over the numbering of the comic Blue Beetle. The sole other known appearance of a character by this name was alongside other guests in writer-artist Steve Ditko's Creeper backup story, "Beware Mr. Wrinkles", in DC Comics' World's Finest Comics #254 (Jan. 1979).
