Spider-Man: One More Day was a four-part miniseries published in 2007, created by J. Michael Straczynski and Joe Quesada along with input from Marvel's editorial department. Marvel's intention behind the miniseries was two-fold. One, they wanted to retcon Peter Parker's marriage to Mary Jane. Two, they wanted to retcon the world knowing Spider-Man's true identity after the events of the Civil War storyline.

For long-time Spider-Man readers, this was a particularly heartbreaking retcon. What is a retcon? Basically, it's a reimagining of fictional work in order to correct inconsistencies. What it meant for Spider-Man comic book readers was taking away all of Peter Parker's personal growth and getting rid of his past as if all the stories we've been through with Spidey never existed. Whether you're a new or an old fan of Spider-Man, here are 10 things you should know about Spider-Man's worst story.

10 Customer Ageism

For those who grew up with the pre-One More Day version of Peter Parker, you might still miss him like an old friend who died. Marvel took a thirty-year-old married Spider-Man and turned him back into a single man in his twenties. This outraged fans. Sure, it's just fiction. Why take it seriously? It's not the story choice by Marvel that really affected fans, it's what Marvel was saying with that choice that had real-world implications.

Marvel was basically saying their older readers are not viable customers anymore. Marvel broke up with their aging readers even though it was the older generations that brought comics to the forefront of mainstream entertainment. Marvel wanted the new hot young readers now that they're successful. One More Day was a financial decision to hook younger readers. Out with the old, in with the new.

9 Death Of A Romance

One of the longest-running romances in comic books was Peter Parker's marriage to Mary Jane. Editor-in-chief Joe Quesada decided there were limitations to storytelling with a married Peter Parker, therefore the marriage was to be no more. Now, taking love away from a protagonist is classic storytelling that creates juicy conflict.

It's the dramatic irony that fans have a problem with. To briefly explain "dramatic irony," it means when an audience knows something about the characters that the characters themselves are unaware of. At the end of One More Day, having made a deal with Mephisto, Peter wakes up having no recollection of ever being married to MJ, but the audiences knew and they were not happy about it.

8 Deal With The Devil

The biggest sin Marvel's One More Day editorial department committed was erasing Peter Parker's marriage to Mary Jane. Peter Parker having adult problems was no longer the agenda, but what was the best way to devolve Peter Parker into a younger version of himself? Magic of course. Peter Parker makes a deal with Marvel's devil Mephisto in order to save his Aunt May who was dying in a hospital of a gunshot wound. Without getting into the specifics of what led Peter Parker into making his bargain with Mephisto, Spider-Man and magic stories are hard to swallow. He's the friendly neighborhood Spider-Man, not the magical Spider-Man.

7 Civil War Walk Back

The events that led to One More Day started with the Civil War series. In the Civil War storyline Peter Parker sides, at first, with Tony Stark, agreeing to unmask himself in front of the world as a gesture to show his commitment to the Superhuman Registration Act. An amazing moment in comics history that was walked back a year later by One More Day. After Mephisto's spell goes into effect, Peter hides his identity from the world once again by asking Dr. Strange to cast a spell. Instead of exploring stories about a Spider-Man with no secret identity, Marvel decided it was easier to return Peter to the status-quo.

6 Aunt May Takes A Bullet

You can't talk about One More Day without talking about the inciting incident for One More Day. Aunt May takes a bullet meant for Peter Parker as a result of him sharing his identity with the world in Civil War. Upon discovering Spider-Man's true identity, Kingpin puts a hit out on Peter Parker. However, Aunt May gets caught in the crossfire.

Aunt May has been taking beatings because of Spider-Man for years. What made this one so different? This time, there was nothing to be done. One More Day wanted to teach Peter Parker the lesson that he should be grateful for his power but he shouldn't use his power to control change. Sometimes life is chaos and there's nothing to be done but accept it. Well, unless you know Mephisto.

5 Back In Black

In reaction to Aunt May being shot, Peter dons the black costume again to hunt down the sniper responsible for pulling the trigger. Spider-Man with his angry suit on vows to kill the person responsible for shooting his Aunt. He tracks down the sniper but the sniper is assassinated before Spidey can learn who hired him. Eventually, Spidey finds out Kingpin is responsible. So, Spidey beats him up but doesn't kill him. Instead, he offers Kingpin a veiled threat that if Aunt May dies, he will kill him. A bit anti-climatic since Aunt May's death is averted by the magic Mephisto deal that was about to unfold in One More Day.

4 Peter Parker vs. Tony Stark

Aunt May's hospital bills were piling up from her gunshot care and Peter needed money. Naturally, he turns to his former friend Tony Stark. Peter essentially holds Tony Stark responsible for Aunt May getting shot because it was Tony who convinced Peter to reveal his identity to the world during Civil War. Tony, however, was still a little miffed at Peter for turning against him and siding with Captain America at the end of Civil War. At first, Tony refuses to help Peter but later changes his mind by sending Jarvis to deliver a check to the hospital. Sometimes no amount of money is enough to save lives. Despite Aunt May's hospital stay being secured, there was little the doctors could do for her. Since money didn't solve the problem, Peter was left with only one recourse, ask his magic friends for help.

3 Mysterious Strangers

This is where One More Day becomes a bit of a magical rabbit hole. Peter has clunky dialogue encounters with mysterious strangers while he grapples with the idea that he may not be able to save Aunt May. With Dr. Strange being unable to help May with magic, Peter begins to have philosophical convos with these strangers.

Turns out the strangers were alternate reality versions of Peter Parker offering him advice and warnings of what his life could have been. The most notable stranger was the little red-haired-girl, whom Peter learns is his daughter that will never exist. All the strangers were just conjurings by Mephisto, ruler of hell.

2 The Child That Never Was

When Peter is on his way to the hospital to be by Aunt May's side at her death, he meets a little red-haired girl who claims to have the solution to Peter's problem. Later, at the end of One More Day, Mary Jane and Peter learn from Mephisto that little girl he conjured was their future daughter May "Mayday" Parker. Mephisto, being the bad guy and all, offers this last twist of the knife right before he takes Peter and MJ's love away, dissolving the reality of their marriage. Mephisto is definitely a child-killer but does it count when the child is hypothetical?

1 Brand New Day

After Peter awakes with no memory of being married to MJ or all the magic nonsense he just went through, it was time for a brand new retconned day. The aftermath of One More Day was met with a negative reaction from both media outlets and fans. The Spider-Man comic book universe as readers knew it was over and all publications were rebooted entirely with the storyline Brand New Day. Now Marvel could rest-assured every future Spider-Man fan would be thoroughly confused if they ever decided to read back issues of Spider-Man pre-2008. Hopefully, this clears up some of the confusion.
