Limited series (comics) in the context of "The Dark Knight Returns"

Batman is a superhero who appears in American comic books published by DC Comics. Batman was created by artist Bob Kane and writer Bill Finger, and debuted in the 27th issue of the comic book Detective Comics on March 30, 1939. In the DC Universe, Batman is the alias of Bruce Wayne, a wealthy American playboy, philanthropist, and industrialist who resides in the fictional Gotham City. His origin story features him swearing vengeance against criminals after witnessing the murder of his parents, Thomas and Martha, as a child, a vendetta tempered by the ideal of justice. He trains himself physically and intellectually, crafts a bat-inspired persona, and monitors the Gotham streets at night. Kane, Finger, and other creators accompanied Batman with supporting characters, including his sidekicks Robin and Batgirl; allies Alfred Pennyworth and James Gordon; love interest and occasional adversary Catwoman; as well as foes such as the Penguin, the Riddler, Two-Face, and his archenemy, the Joker.

Kane conceived Batman in early 1939 to capitalize on the popularity of Superman; although Kane frequently claimed sole creation credit, Finger substantially developed the concept from a generic superhero into something more bat-like. They drew inspiration from pulp fiction characters like the Shadow, Sherlock Holmes, and the Green Hornet. Batman received a spin-off publication, Batman, in 1940. Kane and Finger introduced Batman as a ruthless vigilante who frequently killed or maimed criminals, but he evolved into a just, tempered superhero with a stringent moral code that prohibits killing during the 1940s. Unlike most superheroes, Batman does not possess any superpowers, instead relying on his intellect, fighting skills, and wealth. The 1960s Batman television series used a camp aesthetic, which continued to be associated with Batman for years after it ended. Various creators worked to return Batman to his darker roots in the 1970s and 1980s, culminating with the 1986 miniseries The Dark Knight Returns by Frank Miller.

Watchmen is a comic book limited series by the British creative team of writer Alan Moore, artist Dave Gibbons, and colorist John Higgins. It was published monthly by DC Comics in 1986 and 1987 before being collected in a single-volume edition in 1987. Watchmen originated from a story proposal Moore submitted to DC featuring superhero characters that the company had acquired from Charlton Comics. As Moore's proposed story would have left many of the characters unusable for future stories, managing editor Dick Giordano convinced Moore to create original characters instead.

Moore used the story as a means of reflecting contemporary anxieties, deconstructing and satirizing the superhero concept, and making political commentary. Watchmen depicts an alternate history in which superheroes emerged in the 1940s and 1960s and their presence changed history so that the United States won the Vietnam War and the Watergate scandal was never exposed. In 1985, the country is edging toward World War III with the Soviet Union, freelance costumed vigilantes have been outlawed and most former superheroes are in retirement or working for the government. The story focuses on the protagonists' personal development and moral struggles as an investigation into the murder of a government-sponsored superhero pulls them out of retirement.

The Books of Magic is the title of a four-issue English-language comic book miniseries written by Neil Gaiman, published by DC Comics, and later an ongoing series under the imprint Vertigo. Since its original publication, the miniseries has also been published in a single-volume collection under the Vertigo imprint with an introduction by author Roger Zelazny. It tells the story of a young boy who has the potential to become the world's greatest magician.

The Man of Steel is a 1986 comic book limited series featuring the DC Comics character Superman. Written and drawn by John Byrne, the series was presented in six issues which were inked by Dick Giordano. The series told the story of Superman's modern origin, which had been rebooted following the 1985–1986 series Crisis on Infinite Earths.

DC editors wanted to make changes to the character of Superman, including making him the sole survivor of his home planet Krypton, and Byrne's story was written to show these changes and to present Superman's origin. The series includes the embryonic Kal-El rocketing away from the destruction of Krypton and his birth upon landing in Kansas when he emerged from the artificial womb, Clark Kent as a teenager in Smallville learning that he was found in a crashed space ship, him being hired at the Daily Planet in Metropolis, the creation of his secret identity of Superman, his first meeting with fellow hero Batman, and how he finally learned of his birth parents and from where he came. The series also included the reintroduction of a number of supporting characters, including fellow reporter and love interest Lois Lane and archenemy Lex Luthor, who was re-branded from a mad scientist to a powerful businessman and a white-collar criminal.

DC Vertigo, also known as Vertigo Comics or simply Vertigo, is an imprint of the American comic book publisher DC Comics. Vertigo publishes comics with adult content, such as nudity, drug use, profanity, and graphic violence, that do not fit the restrictions of DC's main line. Its comics include company-owned series set in the DC Universe, such as The Sandman, Swamp Thing, and Hellblazer, and creator-owned works, such as Preacher, Y: The Last Man, and Fables.

Vertigo originated from DC's 1980s adult comic line, which began after DC stopped submitting The Saga of the Swamp Thing for approval by the Comics Code Authority. Following the success of two adult-oriented 1986 limited series, Batman: The Dark Knight Returns and Watchmen, DC's output of adult comics, edited by Karen Berger, grew. By 1992, DC's mature readers' line was editorially separate from its main line and Berger received permission to manage them under a separate imprint. Vertigo was launched in January 1993 with a mix of existing DC ongoing series and new series.

DC Black Label (also referred to simply as Black Label) is an imprint of American comic book publisher DC Comics consisting of original miniseries and reprints of books previously published under other imprints. The imprint intends to present traditional DC Universe characters for a mature audience with stand-alone Prestige Format series. The first title of the imprint, Batman: Damned, was released on September 19, 2018.

"Flashpoint" is a 2011 comic book crossover story arc published by DC Comics. Consisting of an eponymous core limited series and a number of tie-in titles, the storyline premiered in May 2011. The core miniseries was written by Geoff Johns and pencilled by Andy Kubert. The series radically changes the status quo for the DC Universe, leading into the publisher's 2011 relaunch, The New 52.

Flashpoint details an altered DC Universe in which only Barry Allen seems to be aware of significant differences between the regular timeline and the altered one, including Cyborg's place as the world's quintessential hero, much like Superman is in the main timeline, with Superman himself being held captive as a lab-rat by the United States government within an underground facility in Metropolis. In addition, Thomas Wayne is Batman, and a war between Wonder Woman and Aquaman has decimated western Europe.

In comics, an ongoing series is a series that runs indefinitely. This is in contrast to limited series (a series intended to end after a certain number of issues thus limited), a one shot (a comic book which is not a part of an ongoing series), a graphic novel, or a trade paperback, but a series of graphic novels may be considered ongoing as well. The term may also informally refer to a current or incomplete limited series with a predetermined number of issues.
