Spider-Man's Most Famous Kids Just Met for the First Time

SPOILER WARNING: This article contains spoilers for Spider-Girls #1, by Jody Houser, Andrés Genolet, Triona Farrell and Joe Caramagna, on sale now.

For Spider-Man, saving the world is the family business. While everyone Peter Parker knows seems to get caught in his tangled web, Marvel's original web-slinger passed his superpower genes on to his children in several alternate futures.

In Spider-Girls #1, Peter Parker's two most famous kids, Mayday Parker and Annie Parker, meet each other for the first time and team up to take down the Vulture's gang. As if meeting the sister you never had wasn't awkward enough already, Mayday, the Spider-Girl of the 1990s, traveled to Annie's world as part of the universe-hopping crossover Spider-Geddon, where the revived Inheritors are hunting down the Spider-People of the multiverse.

While both Parkers are the super-powered children of Peter and Mary Jane, they've led drastically different lives in totally separate realities.

While Spider-Girl was Marvel's longest-running female-led comic for years, Mayday Parker wasn't originally supposed to... stick around. In the 1990s, Peter and Mary Jane had a daughter named May who was promptly abducted by Norman Osborn before being forgotten about by everyone involved.

In 1998's What If? #105, Tom DeFalco, Ron Frenz and Mark Bagley created an alternate reality where that child grew up to be Mayday Parker. After her spider-powers emerged during a basketball game, she saved her parents and began operating as Spider-Girl.

Thanks to an overwhelming response from fans, Spider-Girl got her own series as part of the MC2 line, which focused on the next generation of Marvel heroes. While the MC2 line only lasted a year, Spider-Girl survived, and her adventures continued on in some form through 2010. While she wasn't quite as strong as her dad, she was faster and used her skills to avoid fights and help reform her villains.

After her solo adventures mostly ended, Spider-Girl suffered one of her life's worst tragedies in the 2014 crossover Spider-Verse. During the Inheritors' first attempt to wipe out the Spider-People of the multiverse, her dad died protecting May and her brother Benji.

Spurred on by his sacrifice, May became Spider-Woman and began hanging out with various Spider-People from other worlds.

On the other hand, Annie Parker has led a fairly sheltered life. During the alternate-reality-spanning crossover Secret Wars, Annie debuted in Amazing Spider-Man: Renew Your Vows #1, by Dan Slott and Andy Kubert. While most of that world's heroes died fighting the villain Regent, Spider-Man survived and protected Mary Jane and their daughter Annie.

After Annie's powers emerged, all three Parkers teamed up to take down Regent as a family. Annie took the name Spiderling, Mary Jane became the tech-based Spinneret, and their adventures continued on until their series ended in September.

When Mayday and her partner Anya Corason, another Spider-Girl, landed in Annie's world, they were surprised to discover that the Inheritors hadn't been there during Spider-Verse. While the real reason is that this world simply hadn't been created yet, the issue hints at the possibility that it could have something to do with Annie's especially strong precognitive Spider-Sense abilities.

As soon as Annie saw Mayday, she sensed the sadness her "sister" felt at seeing another version of her dad in action again, even before they spoke. After the Spider-People's obligatory team-up, this unlikely Parker family reunion got awkward, and momentarily tragic -- Mary Jane realized that Mayday was the daughter she could've had, but died too soon.

While Mayday and Annie haven't gotten too much one-on-one time yet, they will soon, since Annie's parents just took off for the main fight in Spider-Geddon. In between their inevitable bonding time, Mayday and Annie might even discover the key to stopping Spider-Geddon and saving Annie's parents from an early demise.
