List of comics solicited but never published

Comic book stories, issues of comic book limited/ongoing series, or even entire comic book series were written or promoted and solicited for release but, for various reasons, were never published. Some were eventually reprinted elsewhere or published in different forms.

Acclaim Comics

 * Quantum and Woody #22–31 – This series was cancelled by Acclaim after #17 (June 1998), and "uncancelled" 15 months later; as a promotional gimmick, #32 (September 1999) was published to show how the story would have developed if the comic had never been cancelled. In October 1999, the series resumed numbering with #18 and was intended to publish the "missing" issues, but the title was cancelled with issue #21.
 * Unity 2000 #4–6 – Only three issues of this six-issue miniseries were published before its cancellation.

Alternative Comics

 * Detour #2 – Publisher Alternative Comics solicited Ed Brubaker's Detour #2 in 2000, but it never appeared (the first issue had been published in 1997). In 2000, Brubaker promised that "the stories that would have made up the next two issues are being worked on in my disappearing spare time, and hopefully the whole thing will be released as a book of about 100 or so pages in a year or two". Instead, Brubaker embarked in earnest on a mainstream comics writing career with Deadenders (Vertigo Comics), whose dystopic future backdrop was similar to Detour's.

Blackthorne Publishing

 * Battle Beasts #5–6 – Based on the action figure line by Hasbro, this title was to run through at least issue #6. The final issue of the series was #4 and ended on a cliffhanger.
 * Nightmare on Elm Street in 3-D – An ongoing series written by Andy Mangels set to begin in August 1989. The first five issues were to adapt the first five films in the franchise, while subsequent issues would have featured new stories. Mangels later wrote an Elm Street series for Innovation Publishing from 1991 to 1992.
 * Star Wars 3-D #4–7 – Four subsequent issues of this series were planned to be released in 1989 starting in January. The last published issue was #3, released in 1988.
 * Transformers 3-D #4–5 – A three-part storyline in which the Autobots and Decepticons face off against a group of beings known as the Destructons was to begin in 1988. Issue #3 contained the first part of the story, but that was the last issue of the series.

Charlton Comics

 * Charlton Bullseye Special #2–3 – Issue #2 was to be an all-humor book set for release in February 1987, but later pushed back to June. The issue was to contain an Atomic Mouse story by Jim O'Donnelly and Mike Todd, as well as Steve Hauk's "Emperor of da Universe" and Bill Witz's "Murth Man". Issue #3 was originally going to preview a revival of the Charlton Comics title Creepy Things, but the contents of the book changed as Creepy Things was to receive its own title in October 1987.
 * Doctor Morpheus – A six-issue miniseries written by Kent Orlando which was a combination of pulp adventure and science fiction.
 * The Return of the Vengeance Squad – At least four issues were planned for this revival of Charlton's Vengeance Squad series, to be written by T.C. Ford and drawn by Amanda Conner.

Comico

 * Max Headroom and Max Headroom 3-D – An ongoing series and one-shot 3-D comic, the latter written by William Messner-Loebs and illustrated by the Pander Brothers, were planned for the TV character. The cancellation of Max Headroom put the release of the ongoing on hold.

Comics Interview Publications

 * Battle Axe #2–6 – "Berzerker", written by Gary Carlson and pencilled by Angel Medina, was slated to run for the first four issues; "Thorrn: Cursed Warrior", written by Ed DeGeorge, Chris Ecker, and Carlson and pencilled by Stan Timmons, was to run through issue #6. The series never got past issue #1.

CrossGen Comics

 * CrossGen's bankruptcy led to a number of titles—including Sojourn, Negation War, and Brath—being cancelled before completion. Several trade paperback collections were cancelled due to the bankruptcy as well.

DC Comics

 * Action Comics Annual #3 by Chris Claremont and Michael Golden – The original story for this annual was meant to be published in 1990. According to Amazing Heroes Preview Special #10 (February 1990): "And the X-citing news is about the Action Comics Annual, due out this year. It's written by none other than Marvel Mutant Man Chris Claremont, and drawn by not-often-seen Michael Golden. Watch for it". An annual with this number was eventually released in 1991 as part of the Armageddon 2001 crossover event, but contained a different story and was written by Roger Stern.
 * All Star Batgirl – This series was announced at the Toronto Comic Book Expo in 2006. Geoff Johns and J. G. Jones were planning to work on the first six issues, which would present a connection between Barbara Gordon and Arkham Asylum. According to Johns, the series would feature "a mystery centering around Barbara Gordon's transformation into Batgirl", as in Batman: The Long Halloween. The title was described as not taking place in the continuity of All Star Batman and Robin the Boy Wonder.
 * All Star Comics: "The Will of William Wilson" – An unpublished Justice Society of America story from the 1940s by writer Gardner Fox. A good amount of artwork from this story survived and has been reprinted in various publications from TwoMorrows Publishing. In addition, there were three other unused Justice Society scripts penned by Fox - "The Men of Magnifica", "The Emperors of Japan", and "Peril of the Paper Death".
 * All Star Wonder Woman – This series was confirmed at the San Diego Comic Con 2006, with Adam Hughes announced as writer and artist. Hughes intended to retell the character's origin story, and described his approach to the series as an "iconic interpretation" of the character, but explained at the 2010 San Diego Comic-Con International that the project was "in the freezer" for the time being, due to the difficulty involved in both writing and illustrating it himself. As of October 2010, a page on his website indicated that after the current Catwoman series ended with issue #82, Hughes would cease his DC cover work and focus on producing the six-issue All Star Wonder Woman series.
 * Ambush Bug: Year None #6 – A six-issue miniseries, it skipped issue #6 and concluded with issue #7 instead. There was an 11-month gap between #5 (January 2009) and 7 (December 2009).
 * Aquaman II miniseries – A miniseries by writer Neal Pozner and artist Craig Hamilton was published in 1986. A follow-up miniseries was planned, but cancelled due to Hamilton's difficulties with meeting deadlines.
 * Batman: Dark Detective III – In 1977, writer Steve Englehart and artists Marshall Rogers and Terry Austin collaborated on a run of Batman stories in Detective Comics #469-476. A six-issue sequel miniseries titled Batman: Dark Detective was published in 2005. Englehart and Rogers planned a third series of stories, but Rogers' death on March 25, 2007, caused DC to cancel the project.
 * Batman: The Art of Neal Adams – A collection of Adams' best Batman stories, including a cover gallery, was set for October 1992. Comprehensive collections of Adams' Batman work would later be released by DC beginning in the 2000s.
 * Batman: The Brave and the Bold – Paul Kupperberg wrote two unused stories for this tie-in to the animated series of the same name featuring Plastic Man and Guy Gardner as co-stars.
 * Batman: The Widening Gyre #7–12 – In 2010 Kevin Smith wrote a six-issue Batman miniseries called The Widening Gyre, drawn by Walt Flanagan. The series was initially planned as 12 issues, with a long break planned between issues #6 and 7. After issue #6 was published, Smith and Flanagan's work on their reality show, Comic Book Men, extended this planned break further than expected. It was decided in the interim to release the remaining issues as a separate six-issue miniseries to be called Batman: Bellicosity and scheduled for 2014 but, as of now, it remains unpublished.
 * Batwoman miniseries – A miniseries created and written by Dennis O'Neil was planned around the time of Batman's 50th anniversary in 1989. It involved a new Batwoman character described as having more of a motivation to fight crime than the previous Batgirl (Barbara Gordon) and possibly even Batman himself.
 * Before Watchmen: Epilogue – Originally solicited in 2013 as the conclusion to the Watchmen prequels, this one-shot issue was cancelled for unknown reasons.
 * Black Canary miniseries – A miniseries by writer Greg Weisman and artist Mike Sekowsky was planned in 1984. The first issue of the series was pencilled, but the project was ultimately shelved due to the character being used in writer/artist Mike Grell's high-profile three-issue miniseries Green Arrow: The Longbow Hunters. Elements from the ill-fated project were used for Weisman's DC Showcase: Green Arrow short film.
 * Blue Beetle direct market series – Following the cancellation of Blue Beetle's general market series in the late 1980s, a direct market-only series was set to follow. Originally, the plan was to end the first series with issue #21, but the planned follow-up was cancelled as well, due to the belief that there was no audience for a "1960s-type" character like Blue Beetle; as a result, the series ended with issue #24.
 * Blue Devil #32–36 – Blue Devil #31 was to be the beginning of a six-part storyline intended to revive the title, but it became the final issue of the series instead, presumably containing elements of the unpublished story.
 * Captain Atom graphic novel – A Cary Bates/Pat Broderick graphic novel was listed as "upcoming" in Amazing Heroes Preview Special #10, but was described as being on "permanent hiatus" in the following issue.
 * Captain Atom miniseries – A six-issue Captain Atom miniseries was planned to begin in July 1992. Following the events of Armageddon 2001 and Armageddon: The Alien Agenda, Captain Atom was to fake his own death and give up being a superhero, but still had to face the problems associated with his former life. Jonathan Peterson was to write and Michael Netzer and Art Nichols were to be the artists.
 * Checkmate Annual #1 – A 64-page annual was planned for 1989 featuring information about the fictional agency and its members, with a backup story involving the character Judomaster.
 * Comics Cavalcade Weekly – Dave Gibbons provided the cover art for an unpublished comic featuring Superman and the newly acquired Charlton Comics heroes. The series, a weekly anthology, was to appear in 1985 and also tentatively titled Blockbuster, but was presumably shelved following the launch of ongoing series for two of the featured characters, Blue Beetle and Question.
 * Crisis on Captive Earth/Crisis of the Soul – Originally proposed as a 12-issue follow-up to Crisis on Infinite Earths, this story was developed by Paul Levitz, Len Wein, and Jerry Ordway, based on a pitch by Levitz. The main antagonists were the Corrupter, "a living catalyst for evil" who possesses a mysterious gem with ties to Gemworld, and the Manipulator, a rich and powerful man with "much potential for good and evil" who is secretly building a prison for super-villains. Plot points for the story would have included the creation of a new, U.S. government-sanctioned Justice League of America as the only official super-team, a new Freedom Fighters team made up of former Justice League, Titans, Legion of Super-Heroes, Outsiders and Infinity, Inc. members being formed, Star City being destroyed, Elongated Man being forced to kill to save his wife Sue Dibny, and Catwoman, Creeper and Red Tornado, among others, turning evil. Editorial issues led to the project's failure. While thought to have influenced Legends, according to then DC editor Robert Greenberger, no elements of Crisis of the Soul made their way into Legends.
 * DC Comics Classics Library: Shazam! and the Monster Society of Evil – A hardcover reprint of this Golden Age storyline was cancelled in 2009.
 * DC Comics Presents: "In Homage" – A Superman/Thriller story by Robert Loren Fleming and Keith Giffen that was to be produced in the late fall of 1985.
 * DC Comics Presents Annual by Marv Wolfman, George Pérez, and Romeo Tanghal – The Teen Titans were supposed to appear in a DC Comics Presents annual planned for 1984. That year saw the release of DC Comics Presents Annual #3, but it featured Captain Marvel as Superman's co-star. The Wolfman story may have been used for 1985's New Teen Titans Annual #1 as it guest-starred Superman, although the artists were Ed Hannigan and Mike DeCarlo.
 * DC Double Comics Starring Supergirl and Superboy – After Supergirl's cancellation with issue #23 and the planned cancellation of The New Adventures of Superboy after issue #55, both characters were slated to be published together in a 48-page follow-up series. Paul Kupperberg was to write both heroes, with art from Eduardo Barreto and Bob Oksner on the former and Carmine Infantino and Klaus Janson on the latter. The Superboy title was cancelled after issue #54 despite the next issue already being scripted, and the DC Double Comics series was halted due to the events of Crisis on Infinite Earths, which led to both characters being written out of continuity.
 * The "DC Implosion" – During the "DC Implosion", several DC Comics titles were abruptly cancelled, even though a number of the series had issues already completed and ready to be published. Eventually, DC Comics reprinted the stories in black and white to secure their copyright, under the title Cancelled Comic Cavalcade, though this was a limited print run and was not available for sale. A few of the stories were published in other DC comics titles, though some were re-edited prior to publication.
 * The Dead Lady of Clown Town – A Cordwainer Smith story optioned by DC for their line of classic science fiction adaptations. Elaine Lee and Michael Kaluta were the creative team slated to produce the story.
 * Firestorm: Corona – A graphic novel by Gerry Conway and Pat Broderick originally scheduled for Fall 1984 that was never published. According to Conway, the story for the graphic novel was completed, and a panel from the book appeared in Amazing Heroes Preview Special #1.
 * The Flash by Len Wein and Marv Wolfman – An entry in the Winter 1986 Amazing Heroes Preview Special describes a new Flash series by Len Wein and Marv Wolfman. The main character is S.T.A.R. Labs technician MacKenzie Ryan, who possesses energy manipulation powers instead of superspeed. The book was removed from DC's schedule. A Flash series would be released the following year written by Mike Baron, starring former Kid Flash Wally West.
 * The Flash (vol. 3) #13 – In response to a fan question on its blog "The Source" 's Flashpoint Friday feature, DC announced that May 2011's The Flash #12 would be the final issue of the series. At the time, no other details were provided.
 * Freaks by John Byrne – Freaks appeared in a lithography plate published within the History of the DC Universe Portfolio in 1986. Byrne had originally pitched the series to DC, but the series for some reason never surfaced. With some changes, Byrne's concept fit in with his 2112 work to become the John Byrne's Next Men series published by Dark Horse Comics.
 * Generations original plan – Generation Zero and Generation One were part of the original plans for DC's Generations event, which were changed after the departure of DC publisher Dan DiDio.
 * The Great Ten #10 – Although The Great Ten (by Tony Bedard and Scott McDaniel) was solicited and advertised as being a 10-issue miniseries, with each issue focusing on a different character, DC chose to end the series at #9 due to low sales.
 * Green Lantern: "Emerald Interlude" – A three-issue follow-up to the "Emerald Twilight" storyline by Paul Kupperberg, Peter Doherty, and Josef Rubinstein. It was planned to appear in Legends of the DC Universe before that title's cancellation.
 * Green Lantern: "Emerald Twilight" by Gerard Jones – The original storyline for "Emerald Twilight" (which was written by Gerard Jones and set to run in Green Lantern vol. 3 #48–50) involved a conflict between two separate groups of the Guardians of the Universe, and members of the Green Lantern Corps choosing sides. Though this story was advertised and even solicited, it was not considered interesting enough by editor Kevin Dooley, and was replaced with a different story (scripted by Ron Marz) that had Hal Jordan becoming Parallax and destroying the Corps. Jones' version of "Emerald Twilight" has not been published.
 * Green Lantern: "Eyes of the Beholders" – An inventory story by Paul Kupperberg with art by Rick Stasi and Bruce Patterson, which features various Justice League members recalling their earliest experiences with Green Lantern. Kupperberg published the script for this story in his book Son of the Unpublished Comic Book Scripts of Paul Kupperberg.
 * Green Lantern: "The Image" – During Len Wein and Dave Gibbons' run on Green Lantern in the 1980s, Wein planned to introduce a superhero called Image whom he wanted to include in a potential spin-off. Despite being promoted in Amazing Heroes and DC's own preview comic DC Sampler, the character never appeared during their run.
 * Green Lantern Saga – A miniseries about the origins and history of the Green Lantern Corps, the Guardians of the Universe, and the planet Oa was planned for 1990. Science fiction authors such as Larry Niven were scheduled to write the series. Niven later wrote the 1992 one-shot Green Lantern: Ganthet's Tale.
 * Hellbent/King Hell – A two-issue miniseries and crossover by Rick Veitch that was planned for Summer 1989 and was going to tie into DC's mature titles at the time such as Green Arrow, Hellblazer, The Question, Sandman, and Swamp Thing. The story was to involve the aftermath of Lucifer's stepping down as ruler of Hell, with one plot point involving the birth of the Swamp Thing's daughter Tefé Holland. A contract dispute with DC led Veitch to pull out of the crossover.
 * Holy Terror, Batman! – A proposed 122-page graphic novel by Frank Miller, announced in 2006, but no longer a project associated with the Batman character or DC Comics. In 2010 Miller said that he was no longer working on the project. He stated in June the same year that Holy Terror was in progress, but without Batman. The book was eventually released by Legendary Comics as Holy Terror.
 * Hybrid – An ongoing series was planned for the Teen Titans foes, the Hybrid, for 1993, with Len Wein as the writer and Art Nichols and George Pérez as the artists.
 * Infinity, Inc.: The Generations Saga Vol. 2 – A hardcover book containing issues #5–18 and Annual #1 was solicited for release for July 2012, but was cancelled.
 * JLA/Avengers – In 1983, Roy Thomas and Gerry Conway were to be the co-writers of a JLA/Avengers intercompany crossover drawn by George Pérez. Editorial disputes between DC and Marvel caused the project's cancellation. It was not until 2003 that a crossover between the two teams was published, albeit in a completely different story by Kurt Busiek and Pérez. All of the original story's existing penciled art was published in the hardcover collection of the 2003 JLA/Avengers crossover.
 * Justice League International – Following the three Justice League series being published at the time (Justice League America, Justice League Europe, and Justice League International Quarterly), a fourth series starring the Injustice League was in the planning stages for 1991, as well as a series featuring the Conglomerate, the superhero team which premiered in the first issue of the Quarterly title.
 * Justice League of America – A story about the last case of the original Justice League of America by William Messner-Loebs and Adam Kubert. Listed in 1989's Amazing Heroes #157, DC declared it a "dead" project.
 * Larry Harmon's Laurel and Hardy #2 – In 1972, DC published a single issue of a comic book series based on the Laurel and Hardy cartoon series produced by Larry Harmon. The cover for the unpublished second issue appears in The DC Vault.
 * The Legend of King Arthur and the Knights of the Round Table by Gerry Conway and Nestor Redondo – House advertisements in DC Comics cover-dated September 1975 promoted a four-part King Arthur miniseries to be published in the Treasury Edition format.

 * Marvel and DC Present The Uncanny X-Men and The New Teen Titans #2 – A sequel to the popular X-Men/New Teen Titans crossover was initially announced in the letters page of New Teen Titans #29 and scheduled for release around Christmas 1983. It was planned to feature Marv Wolfman as writer and George Pérez as artist, with the villains in the story being Brother Blood and the Hellfire Club. Plans for the book were eventually cancelled because of the problems that affected the JLA/Avengers crossover.
 * Metal Men miniseries – A 1984 miniseries by Robert Kanigher and Irv Novick would have involved the Metal Men starring in their own movie. DC never put the book on their schedule.
 * Metropolis by Steve Gerber and Frank Miller – The "line name" for a proposed revamp of Superman, Batman and Wonder Woman.
 * Mr. Monster/Swamp Thing – An intercompany crossover between DC and Eclipse Comics was anticipated for late fall of 1986, then later scheduled for 1988. The crossover was to be co-written by Michael T. Gilbert and Alan Moore with art by Gilbert, Stephen R. Bissette, and John Totleben.
 * New Teen Titans: Genesis – A reprint of the first appearances of the New Teen Titans by Marv Wolfman and George Pérez was planned to ship in September 1992.
 * Nightwing miniseries by Art Thibert – Nightwing's first miniseries was planned to be written and drawn by Art Thibert and dealt with Nightwing's personal struggles while tracking down the person responsible for putting his girlfriend Starfire in a coma. Instead, a different series by Dennis O'Neil and Greg Land was released in 1995.
 * The Outsiders new format series – The Outsiders #28 (a Millennium crossover) was the final issue of the book, but was going to be replaced with a "new format" series in 1988. A new Outsiders title would not come out until 1993.
 * Pandora Pann – Most of the preview story for this series by writer Len Wein and artist Ross Andru (scheduled to be printed in Saga of the Swamp Thing #5) was pencilled, but for unknown reasons the series never materialized.
 * Power Squad – An all-female super team named the "Power Squad" was proposed by Jack C. Harris and Trevor Von Eeden, but the idea was not approved for publication.
 * Robotech Defenders #3 – This series, based on the Revell line of plastic models, was originally scheduled as a three-part miniseries in 1985. It was reduced to the first normal-sized issue and a 32-page second issue with no advertisements.
 * Salvo – A series by writer Steven Grant and artists Pat Gabrielle and Mike DeCarlo, which was described by editor Michael Golden as "The Punisher as done by Lucy and Desi", was planned for early 1993.
 * Secret Origins (vol. 2) – Following the series' cancellation after issue #50, further annuals and specials were planned. In addition, stories were planned for Jericho in issue #6, Aquaman and the Ray in issue #30, a post-Crisis on Infinite Earths update of past Justice League/Justice Society team-ups in Annual #2, Geo-Force and Terra in issue #49, and Dial H for Hero, the Space Canine Patrol Agents, and Ultra the Multi-Alien in other issues. Also, the story of the Legion of Super-Heroes' clubhouse from issue #46 was originally a different tale drawn by Kurt Schaffenberger which was tied to Superman's Pre-Crisis history, and was replaced by the Curt Swan-drawn version which saw print.
 * Seventh Generation – A six-issue crossover series planned for 1989, it was canceled due to DC's plans for the release of Batman that year.
 * The Shadow #20–24 – Andy Helfer and Kyle Baker's run on The Shadow was planned to end with issue #24. The series was cancelled after issue #19.
 * Shazam! miniseries and ongoing series by Roy Thomas – A Roy Thomas/Don Newton Shazam! miniseries was planned for 1984 or 1985, in which Captain Marvel meets a black superhero from Earth-1 who also received his powers from the wizard Shazam. Thomas later co-wrote a Captain Marvel miniseries in 1987, Shazam! The New Beginning, although the art was by Tom Mandrake since Newton died in 1984. In addition, an Amazing Heroes Preview Special from 1989 contained a short blurb about a possible Shazam! series featuring Thomas' version of the character following his run in Action Comics Weekly. This series never appeared prior to Jerry Ordway's reboot in the 1994 graphic novel The Power of Shazam!.
 * Showcase #50: "Yankee Doodle Dandy" – Showcase #50 was to feature the debut of Yankee Doodle Dandy, a spy character created by editor Lawrence Nadle. Nadle's death caused the story to be shelved, but the character was resurrected in 1992 for Grant Morrison's Doom Patrol run.
 * The Silver Age by James Robinson – A four-issue follow-up to Robinson's The Golden Age, which was being developed but did not happen. According to Robinson, later books such as JLA: Year One and DC: The New Frontier have since made the series unnecessary.
 * Sonic Disruptors #8–12 – This 12-issue miniseries by writer Mike Baron and artist Barry Crain was cancelled after issue #7 due to poor sales. A Sonic Disruptors graphic novel to finish the storyline was also planned with art by Mike Mignola.
 * Soul Love – Part of a prospective line of black-and-white magazines geared toward adults, this 1971 Jack Kirby title was supposedly killed because of a possible backlash among Southern retailers.
 * Space Ranger miniseries – An eight-issue miniseries starring the science fiction character was to ship in October 1992, written by Michael Jan Friedman and pencilled by John Calimee.
 * Spectre by Steve Gerber – Gerber was to have been the writer of the 1980s relaunch of the Spectre series, but scheduling difficulties led DC to replace him with Doug Moench.
 * Spectre graphic novel – Roy Thomas was in discussions with Jerry Ordway to do a graphic novel about the Spectre after they completed the America vs. the Justice Society miniseries. Thomas wanted the story to explain the various inconsistencies in how the character was portrayed by different writers over the years.
 * Starfire #9 – Starfire #8, which turned out to be the last issue of the series, contained an announcement on the story's final page that the next issue would be released during the second week of September 1977.
 * Starman #46 – Solicited as the last issue of the first Starman series, the title was cancelled after issue #45 instead.
 * Sugar and Spike (vol. 2) – The series was published in the United States from 1956 through 1971 for 98 issues, when due to creator Sheldon Mayer's failing eyesight that limited his drawing ability, Sugar and Spike ceased to appear. Later, after cataract surgery restored his eyesight, Mayer returned to writing and drawing Sugar and Spike stories, continuing to do so until his death in 1991; these stories appeared in overseas markets and only a few have been reprinted in the United States. The American reprints appeared in the digest sized comics series The Best of DC #29, 41, 47, 58, 65 and 68. Sales on the "Sugar and Spike" issues of The Best of DC were strong enough that DC announced plans for a new ongoing series featuring the characters. The project was never launched for unknown reasons.
 * Superman #712 by Chris Roberson – Issue #712 was scheduled to feature a revival of the 1990s supporting character Sinbad. When the issue came out, a previously unreleased story by Kurt Busiek ("Lost Boy: A Tale of Krypto the Superdog", which was originally planned for Superman #659) was published in its place. It was believed that the change was due to Sinbad's Muslim heritage, but DC's explanation was the story didn't fit as part of the ongoing "Grounded" storyline.
 * Superman 3-D – According to DC's promotional giveaway brochure DC Releases #46 (March 1988), a Superman 3-D one-shot issue was planned for 1988. It was to be written and penciled by John Byrne and inked by Ty Templeton with 3-D effects by Ray Zone. A "major new Superman foe" named "Tantrum" was to have been introduced. Byrne and Zone would later collaborate on a Batman 3-D graphic novel. A Superman 3-D one-shot was published in December 1998 by a different creative team.
 * Superman: An Evening with Superman – A graphic novel by Barry Windsor-Smith entitled "An Evening with Superman" was originally announced by DC in 1998, but has not been published as of 2016. Superman: The Complete History – The Life and Times of the Man of Steel features an excerpt of this story.
 * Superman: "Supermite!" – An unpublished 12-page Superman story from 1944 written by Jerry Siegel.
 * Superman: "The K-Metal from Krypton" – An unpublished Superman story from 1940 that not only introduced an early version of kryptonite, but had Lois Lane learn that Superman is really Clark Kent. The original script and outline were rediscovered by Mark Waid in 1988 and there was an online effort to restore and publish the story.
 * Swamp Angel – A three-issue Prestige format miniseries by Mike Grell which would have told the story of a Southern family beginning with the American Civil War and spanning three generations.
 * Swamp Thing #25 - The existing scripts and artwork from this unpublished issue of the first Swamp Thing series were reprinted in the trade paperback Swamp Thing: The Bronze Age Volume 2.
 * Swamp Thing (vol. 2) by Rick Veitch – Veitch's original plans for the end of his run on Swamp Thing involved having the birth of Tefé Holland (the daughter of the Swamp Thing and Abby Holland) in issue #92, and then remaining on the title for a year afterward to set up her powers. Following a contract dispute with DC, Veitch instead decided not to stay on the book past issue #92. Then, Veitch's story for issue #88 (where the Swamp Thing meets Jesus Christ during a time travel story arc) was cancelled by DC Comics due to their fear of controversy from religious groups; this caused Veitch to quit the title altogether before finishing the storyline, which another writer (Doug Wheeler) had to take over.
 * Swamp Thing (vol. 2) by Neil Gaiman and Jamie Delano – Gaiman and Delano were set to take over writing the ongoing Swamp Thing series following Rick Veitch's run on the book, but bowed out after the controversy over Veitch's Swamp Thing #88. Gaiman's only work on the title appeared in Swamp Thing Annual #5, while Delano's was in Swamp Thing #77.
 * Swamp Thing: Deja Vu – A three-issue miniseries was scheduled for 1990 by Len Wein and artist Bernie Wrightson. It was partially drawn by Wrightson before he left the project and there was no attempt to complete the series with another artist.
 * Tales of the Legion of Super-Heroes #355–360 – DC's Legion reprint title was set to run through at least issue #360, according to the run-down of issues listed in Amazing Heroes Preview Special #5.
 * Teen Titans Spotlight – Stories planned for future issues of this Teen Titans anthology series included a Raven and Vigilante two-part story, as well as solo stories starring Cheshire, Doctor Light, Red Star, and Azrael.
 * Thriller Special – A Thriller story titled "Naked Steel" by Robert Loren Fleming and Keith Giffen was intended by Fleming to both revive the characters and bring them closer to his original vision. Announced as being released in the summer of 1985, it was later revealed that the announcement was premature and DC never got back to Fleming about the book.
 * Tomahawk miniseries – A five-issue miniseries written by William Messner-Loebs and illustrated by Thomas Yeates set in the early days of the American Revolution. Yeates later provided the artwork for the Vertigo Visions – Tomahawk one-shot in 1998, which was written by Rachel Pollack.
 * Twilight of the Superheroes – A company-wide crossover and attendant maxiseries proposed by Alan Moore in the late 1980s prior to his public split with DC. The series imagined a dark future where various superhero clans warred for global dominance. Moore's split with DC, as well as the very dark nature of the story, meant that the series never got beyond the proposal stage, although a number of story elements that Moore had suggested were later worked into ongoing series. Moore's proposal was leaked on the Internet in the early 1990s, and the complete text was published by DC in the hardcover DC Through the '80s: The End of Eras in 2020.
 * Valda – An aborted Roy Thomas/Todd McFarlane four-issue miniseries spun off from Thomas' Arak, Son of Thunder title.
 * Vigilante miniseries – Following Vigilante #50 in 1987, a miniseries was planned for the character, but Vigilante ended up killing himself in that issue and the miniseries never appeared.

The material was published in France by Arédit in 1979.
 * Ms. Marvel #24–25 – Ms. Marvel #24–25 were written and mostly drawn, but the series was cancelled with issue #23 (April 1979).

Destiny, Avalanche, and Pyro would instead debut in Uncanny X-Men #141 and Rogue would debut in Avengers Annual #10.
