Captain Marvel Jr. (Freddy Freeman) is a fictional character, a superhero originally published by Fawcett Comics and currently in the DC Comics Universe. A member of the Marvel Family team of superheroes, he was created by Ed Herron and Mac Raboy, and first appeared in Whiz Comics #25 in December 1941.
Captain Marvel Jr.'s alter-ego is Freddy Freeman, a crippled newsboy saved by Captain Marvel from the villainous Captain Nazi. Junior derives his powers from Captain Marvel himself, while the other Marvels derive their powers from the wizard Shazam. By saying the name Captain Marvel, Freddy is transformed into the teenaged Captain Marvel Jr. Unlike Captain Marvel and the modern-era version of Mary Marvel, Junior remains a teenager in his transformed state.
In The Trials of Shazam! maxi-series published from 2006 to 2008, Freddy Freeman is made to undergo six trials to prove himself worthy of succeeding Captain Marvel, who takes over the wizard Shazam's post on the Rock of Eternity. Upon completion of the Trials, Freddy assumes the superhero name Shazam.
