Twilight of the SuperheroesTwilight of the Superheroes.

Twilight of the Superheroes is the title of a proposed comic book crossover that writer Alan Moore submitted to DC Comics in 1987 before his split with the company. Although various elements suggested by Moore later occurred in various comics, Twilight was never produced. The proposal gained fame after surfacing on the internet in the 1990s where its status as a lost work by one of the superstars of the medium, as well as its dark treatment of superheroes, garnered much attention.
