List Of What If Issues

The Marvel Comics anthology series '' What If?'' tells alternate reality stories outside the mainstream Marvel Universe continuity, which the company sets on what it calls Earth-616. A number of these stories have been set on alternate Earths in the Marvel Comics Multiverse (i.e., multiple universes) for which Marvel has given official numerical designations.

*What if Aunt May had died instead of Uncle Ben?
*''Wha—Huh?'' (humor issue)

The series was later collected into a trade paperback entitled ''What If...?: Why Not''.

Volume 4 (early 2006)

The February 2006 one-shot issues took place in a single fictional universe, dubbed Earth-717, with four of the six stories more like DC's ''Elseworlds'' with various heroes in historical periods.

*What if Captain America had lived in the American Civil War?
*What if the Fantastic Four were Russian cosmonauts?
*What if the Sub-Mariner had grown up on land instead of Atlantis?
*What if Daredevil had lived in feudal Japan?
*What if Thor was a Herald of Galactus?
*What if Wolverine was Public Enemy Number One?

The series was later collected into a trade paperback entitled ''What If...?: Mirror Mirror''.

Volume 5 (late 2006)

The November 2006 one-shot issues were based on major storylines or crossovers:

*''What If: Avengers Disassembled'' - What if the Scarlet Witch had not acted alone?
*''What If: Spider-Man: The Other'' - What if Peter Parker had rejected his inner spider?
*''What If: Wolverine: Enemy of the State'' - What if Wolverine was never deprogrammed?
*''What If: Age of Apocalypse'' - What if both Xavier and Magneto were killed by Legion?
*''What If: X-Men: Deadly Genesis'' - What if Vulcan became the leader of the X-Men?

The series was later collected into a trade paperback entitled ''What If...?: Event Horizon'' featuring the cover from the Spider-Man one-shot.

Volume 6 (2007)

The sixth series of ''What If?'' continued the theme of the previous series of examining possible alternatives for major storylines.

*''What If: Planet Hulk''
** What if Caiera had survived the destruction on Sakaar instead of the Hulk?
** What if the Hulk had landed on the planet the Illuminati had intended for him?
** What if the Hulk had reverted to Bruce Banner when he crashed on Sakaar?
*''What If: Annihilation''
** What if the Annihilation Wave reached Earth?
*''What If: X-Men: Rise and Fall of the Shi'ar Empire''
** What if Vulcan absorbed the energies of the M'Kraan Crystal and became Phoenix Force?
*''What If: Civil War''
** What if Captain America led all the heroes against the Superhero Registration Act?
** What if Iron Man lost the Civil War?
*''What If: Spider-Man vs. Wolverine''
** What if Spider-Man had remained in 1980s Russia after an accidental death?

The series was also due to feature ''What If?: The New Fantastic Four'', which featured the "original" New Fantastic Four with Spider-Man, Wolverine, Ghost Rider, and Hulk teaming up, as seen in ''Fantastic Four'' #347-349 and #374. This story was halted due to the death of artist Mike Wieringo, and was released as a 48-Page Special as a tribute in June 2008. All the issues of this run, aside from the New Fantastic Four one, were later collected into a trade paperback simply entitled ''What If? Civil War''. The version of the "New" Fantastic Four is also erroneous, as the Ghost Rider of that time period had been Danny Ketch, not Johnny Blaze, who appears in the issue instead for unexplained reasons (in reality, Wieringo had drawn the wrong Ghost Rider in his initial pages by mistake and it was not noticed until after his death).

Volume 7 (2008)

This series continues the theme of alternatives for three recent Marvel events along with two around a classic event. The New Fantastic Four story was a sequel to the one-shot ''What If?'' released previously, seeing Iron Man replace Ghost Rider in an alternate take on the ''Infinity Gauntlet'' storyline. However, this series also features a storyline featuring the Runaways that runs through all five comics. This series was released between December 2008 and January 2009.

* ''What If: House of M'' - What if the Scarlet Witch had said 'No more powers' instead of 'No more mutants'?
* ''What If: Fallen Son: The Death of Captain America'' - What if Iron Man had been killed instead of Captain America?
* ''What If: The Infinity Gauntlet'' - What if the New Fantastic Four had battled Thanos?
* ''What If: Spider-Man: Back in Black'' - What if Mary Jane had been shot instead of Aunt May?
* ''What If: Secret Wars'' - What if Doctor Doom had kept the Beyonder's power?
* ''What If: Runaways'' - What if the Runaways had become the Young Avengers? (Runs through all five above issues)

The seventh series was later collected into a trade paperback entitled ''What If...?: Secret Wars'' featuring the cover from the ''Secret Wars'' one-shot.

Volume 8 (2009)

At Fan Expo Canada '09, it was revealed a new five-part ''What If'' series would be released, featuring five one-shot issues, each with two alternatives for the focused event, except for ''Daredevil vs. Elektra'', which had only one story. As a back-up feature in the other four one-shot issues, there is a humorous ''Say What?'' short story.

*''What If? Spider-Man: House of M''
** What if Emma Frost had not mindwiped Gwen Stacy?
** What if the Scarlet Witch had let Gwen Stacy and her son cross to the default reality and survive?
*''What If? Secret Invasion''
