Lobo: The Last Czarnian (1990)

Lobo was introduced as a regular character in Keith Giffen and Roger Slifer’s Green Lantern and Teen Titans spin-off Omega Men. At that time, he was a Velorpian whose entire race had been exterminated by Psions and was partnered with Bedlam, whom he later killed; his origin was later retconned.

After a well-received appearance in Justice League International, Lobo became a regular character in L.E.G.I.O.N. and its successor series R.E.B.E.L.S..

In 1990, he appeared in his four-issue own miniseries, Lobo: The Last Czarnian, plotted by Giffen, written by Alan Grant and with art by Simon Bisley, which changed his origin story: he became the last Czarnian after violently killing every other member of the species. That miniseries led to many subsequent miniseries and specials.

Crisis on Infinite Earths (1985)

Crisis on Infinite Earths was published by DC Comics from 1985 to 1986, consisting of an eponymous 12-issue, limited series comic book and a number of tie-in books. It was produced by DC Comics to simplify its then-50-year-old continuity. The series was written by Marv Wolfman and illustrated by George Pérez (pencils and layouts), Mike DeCarlo, Dick Giordano and Jerry Ordway (inking and embellishing). The series removed the multiverse concept from the fictional DC Universe, depicting the death of long-standing characters Supergirl and the Barry Allen incarnation of the Flash. Continuity in the DC Universe is divided into pre-Crisis and post-Crisis periods. The Flash was later reborn.

The series’ title was inspired by earlier multiverse crossover stories of parallel Earths, such as “Crisis on Earth-Two” and “Crisis on Earth-Three“, and involves almost every significant character in every parallel universe of DC Comics history. It inspired the titles of three DC crossover series: Zero Hour: Crisis in Time! (1994), Infinite Crisis (2005–2006), and Final Crisis(2008).

Swamp Thing (1970’s)

The Swamp Thing character first appeared in House of Secrets #92 (June–July 1971). After the success of the short story in the House of Secrets comic, the original creators were asked to write an ongoing series, depicting a more heroic, more contemporary creature. InSwamp Thing #1 (October–November 1972) Wein and Wrightson updated the time frame to the 1970s and featured a new version character: Alec Holland, a scientist working in the Louisiana swamps on a secret bio-restorative formula “that can make forests out of deserts”. Holland is killed by a bomb planted by agents of the mysterious Mr. E (Nathan Ellery), who wants the formula. Splashed with burning chemicals in the massive fire, Holland runs from the lab and falls into the muck-filled swamp, after which a creature resembling a humanoid plant appears. Roy Thomas and Gerry Conway, who co-created Man-Thing for Marvel Comics a year and a half earlier, thought that this origin was too similar to that of their character, and Wein himself had written a Man-Thing story that was published with a June 1972 cover date, but he refused to change the origin in spite of some cajoling by Conway, who was his roommate at the time. Marvel, however, never took the issue to court, realizing the similarity of both characters to The Heap.

Adventure Comics (Silver Age)

Adventure Comics was published by DC Comics from 1938 to 1983 and revived from 2009 to 2011. In its first era, the series ran for 503 issues (472 of those after the title changed from New Adventure Comics), making it the fifth-longest-running DC series, behind Detective Comics, Action Comics, Superman, and Batman. It was revived in 2009 by writer Geoff Johns with the Conner Kent incarnation of Superboy headlining the title’s main feature, and the Legion of Super-Heroes in the back-up story. It returned to its original numbering with #516 (September 2010). The series finally ended with #529 (October 2011), prior to DC’s The New 52 company reboot.

Action Comics (2020’s)

With Superman captured on Warworld and banished to the lower catacombs, he’ll need to team up with other enslaved gladiators to turn the hordes of Warworld against their masters.

Adventures of Superman (2000’s)

The Adventures of Superman was numbered from issue #424 (January 1987) to issue #649 (April 2006), for a total of 228 monthly issues including issue #0 (October 1994) published between issues #516 and #517 as a tie-in to the Zero Hour limited series and issue #1,000,000 (November 1998) as a tie-in to the DC One Million limited series and nine Annuals published between 1987 and 1997.

As of the start of 2002, the integration between the Superman titles became less frequent, and the remaining issues of The Adventures of Superman commonly carried self-contained stories. Issue #600 (March 2002) was a double-sized special featuring Superman combating Lex Luthor.The final issue (#649) was part of a three-part crossover with Superman and Action Comics, an homage to the Earth-2 Superman in the wake of events in the limited series Infinite Crisis.

For its last two years, The Adventures of Superman was written by Greg Rucka. His stories included the villain Ruin, the attempted assassination of Lois Lane and a number of Mister Mxyzptlk appearances.

Batman V3: Rebirth (2016)

In June 2016, the DC Rebirth event relaunched DC Comics’ entire line of comic book titles. Batman was rebooted as starting with a one-shot issue entitled Batman: Rebirth #1 (August 2016). The series then began shipping twice-monthly as a third volume, starting with Batman vol. 3, #1 (August 2016). The third volume of Batman was written by Tom King, and artwork was provided by David Finch and Mikel Janín. The Batman series introduced two vigilantes, Gotham and Gotham Girl.

DC Comics ended the Rebirth branding in December 2017, opting to include everything under a larger “DC Universe” banner and naming. The continuity established by Rebirth continues across DC’s comic book titles, including volume one of Detective Comics and the third volume of Batman.

Justice League (1987)

The 1986 company-wide crossover “Legends” concluded with the formation of a new Justice League. The new team was dubbed “Justice League” then “Justice League International” (JLI) and was given a mandate with less of an American focus. The new series, written by Keith Giffen and J. M. DeMatteis with art by Kevin Maguire (and later Adam Hughes), added quirky humor to the team’s stories. In this incarnation, the membership consisted partly of heroes from Earths that, prior to their merging in the Crisis on Infinite Earths, were separate. The Giffen/DeMatteis team worked on Justice League for five years and closed out their run with the “Breakdowns” storyline in 1991 and 1992. The series’ humorous tone and high level of characterization proved very popular.

Catwoman (1989)

The 1989 Catwoman limited series, written by Mindy Newell and with art by J.J. Birch, expanded upon Miller’s Year One origin. This storyline, known as “Her Sister’s Keeper”, explores Selina’s early life as a dominatrix and the start of her career as Catwoman. The story culminates with Selina’s former pimp, Stan, abducting and beating her sister Maggie, who, in contrast to Selina, is a nun. Selina kills Stan to save her sister, and gets away with it. Most of this is revealed in the former series, but is expanded upon in “Her Sister’s Keeper”.

Action Comics (1970’s)

Mort Weisinger retired from DC in 1970 and his final issue of Action Comics was issue #392 (September 1970). Murray Boltinoff became the title’s editor until issue #418. Metamorpho was the backup feature in issues #413-418 after which the character had a brief run as the backup in World’s Finest ComicsJulius Schwartz became the editor of the series with issue #419 (December 1972) which also introduced the Human Target by Len Wein and Carmine Infantino in the back-up feature. Green Arrow became a backup feature in #421 and ran through #458, initially rotating with the Human Target and the Atom. Between issues #423 (April 1973) and #424 (June 1973), the series jumped ahead by one month due to DC’s decision to change the cover dates of its publishing line.

A new version of the Toyman was created by Cary Bates and Curt Swan in issue #432 (February 1974). Martin Pasko wrote issue #500 (October 1979) which featured a history of the Superman canon as it existed at the time and was published in the Dollar Comics format.
