limited DC's willingness to use the characters, and as a result most of them appeared very rarely once the Shazam! series ended in 1978. In 1987, DC Comics relaunched Captain Marvel in a miniseries, Shazam!: The New Beginning, and purchased the full rights to all of the Fawcett superhero characters by 1991. Captain Marvel has not proven to be a modern-day success for DC to the degree it had been for Fawcett, due in part to DC not being able to properly promote the character under the "Captain Marvel" name, which is a Marvel Comics trademark. As a result, when DC Comics rebooted its entire comic line under the New 52 initiative in 2011, Captain Marvel was renamed "Shazam" and was reintroduced to comics the following year under that name. National v. Fawcett is still an often-referenced case in the areas of copyright law and plagiarism because of its readily-accessible subject matter, and the popularity of its author, Judge Hand, among legal scholars. It was occasionally nicknamed Kent v. Batson, a reference to the two superheroes' respective secret identities: National's Clark Kent and Fawcett's Billy Batson. Superduperman vs. Captain Marbles In Mad #4, 1953, the story "Superduperman" was published. While it did not specifically reference the lawsuit, the story recounts the battle between Superduperman and "Captain Marbles", which ends in the defeat of Captain Marbles. See also Kimble v.
