Капитан Марвел
After Fawcett Comics' success with their first superhero character, Captain Marvel, the company decided to introduce a spin-off character. Although Captain Marvel had been given part-time sidekicks in the form of the look-alike Lieutenant Marvels in "Whiz Comics" #21 (Sept. 1941), Fawcett Comics editor Ed Herron wanted to introduce a distinctive spin-off character. Captain Marvel transformed from teenage boy to adult superhero with a magic word; Herron decided his new character would remain a teenager to differentiate him from Captain Marvel. Fawcett staff artist Mac Raboy designed the new character, named Captain Marvel Jr., using a more realistic style parting with C.C. Beck's more cartoony artwork for the Captain Marvel stories. Whereas Captain Marvel changed identities by saying "Shazam", Captain Marvel Jr. says "Captain Marvel" to transform; this was intended to serve as a frequent reminder to readers to buy the Captain Marvel Sr. books.
