Not to be confused with Sturgis Butterfield of Hero Hotline, who has also used the name Mr. Muscles.

Mr. Muscles is a fictional comic book superhero created in 1956 by writer Jerry Siegel for Charlton Comics, and drawn by Bill Fraccio for the first of two issues of his namesake comic, and by the team of penciler Charles Nicholas and inker Vince Alascia for the second. A young Dick Giordano provided the premiere issue's cover.

Fictional character biography
Wrestler Brett Carson obtained super strength 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, the blond-haired hero 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 & Aug. 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).
