Aquaman, published by DC Comics was created by Paul Norris and Mort Weisinger. The character debuted in More Fun Comics #73 (November 1941). Initially a backup feature in DC’s anthology titles, Aquaman later starred in several volumes of a solo title. During the late 1950s and 1960s superhero-revival period known as the Silver Age, he was a founding member of the Justice League of America. In the 1990s Modern Age, Aquaman’s character became more serious than in most previous interpretations, with storylines depicting the weight of his role as king of Atlantis.
Later accounts reconciled both facets of the character, casting Aquaman as serious and brooding, saddled with an ill reputation, and struggling to find a true role and purpose beyond his public side as a deposed king and a fallen hero. The character appeared in the 2016 film Batman v Superman: Dawn of Justice, portrayed by Jason Momoa, with a solo film following in 2018.
Showcase has been the title of several comic anthology series published by DC Comics. The general theme of these series has been to feature new and minor characters as a way to gauge reader interest in them, without the difficulty and risk of featuring “untested” characters in their own ongoing titles. The original series ran from March-April 1956 to September 1970 suspending publication with issue #93, and then was revived for eleven issues from August 1977 to September 1978.
