Warriors of the Great Web

Sometime within the eight months following the Incursions, Mayday joined Spider-Gwen, Spider-Man Noir, Spider-UK, Spider-Man India, Spider-Ham and Anya Corazon in protecting Earths without Spider-Men. After a romp on Earth-3015, Mayday confided to Gwen that she was still too concerned in leaving behind her mom and brother and told them to call her if they needed her. However, when an army of Electros attacked a nearby building in an attempt to steal silver, the two Spider-Women jumped into action, only for Gwen to get captured when Mayday attempted to rally the other Spiders.^[14] She then returned to Loomworld and informed Spider-Man (Paviitr Prabhakar), Spider-Ham (Peter Porker), and Karn of the situation regarding Gwen's kidnapping. She was later seen alongside the other members of the Warriors of the Great Web in order to investigate the scene of Gwen's kidnapping.^[15]

Spider-Geddon and Spider-Girls

In the 2018 comics event Spider-Geddon and the spin-off mini-series Spider-Girls, Mayday is once again recruited to help the Web Warriors combat The Inheritors, who had managed to escape their confinement and had set up residence on Earth 616. Mayday and Anya are sent to the world of Amazing Spider-Man: Renew Your Vows to recruit Annie May Parker, the second child Peter and MJ conceived after their version of Mayday died at birth.

With Annie's parents assisting the war effort against The Inheritors on Earth 616, Mayday and Anya try to help Annie unlock the mysteries of the Spider-Scrolls and find a means of stopping their enemies. Annie learns that she is the pattern weaver, the fourth Spider involved in the prophecy alongside Mayday's brother Benjy (The Scion), Silk (The Bride), and The Other. After battling two of the Inheritors on Annie's world, Mayday, Anya and Annie retreat to Loomworld where they find the web of destiny has been sabotaged. They then use the scrolls to return to Earth 616 and use Annie's web-weaving powers to help the web warriors defeat the Inheritors and their leader Solos. Afterwards, it is revealed that The Other has resurrected Mayday's father back on her own world^[21]

Return To Normalcy & End of The Spider-Verse

In the End of Spider-Verse event, Mayday at some unspecified point is attacked and infected by one of the many Spider-Wasps unleashed on the multiverse by the demonic Shathra, turning her against the other warriors of the web. ^[22], her father is one of Shathra's prisoners, The Other having transformed him into a savage Spider-Beast.^[23] The Other, with the aid of Spinnerett and other heroes, helps to free the Spiders from Shathra's control and he and Mayday are finally reunited. Ultimately, it is the 616 variant of Arana who helps restore Mayday's father to normal using her mystic totem powers.

Shortly after this ordeal, Mayday settles back into her regular life, allowing her hair to grow longer again and reverting back to her original Spider-Girl codename. No longer dating Wes, Mayday began to flirt with a new student called Jason, and aided both pairs of Lady Hawks thwart a nearby crime. With her parents reconnecting on date nights, Mayday would babysit her brother Benjy, now having grown into a tyke and able to speak^[24]

Main cast

• Peter Parker – Peter is May and Ben's father, who happens to be Spider-Man but has retired from superhero business. His last battle cost him one of his legs, and he is now working as a police scientist. He also despises May's former boyfriend Gene, because he is the son of his high school bully, Flash Thompson. He has returned to the role of Spider-Man on occasion, although his artificial leg limits his activities. During the Spider-Verse event he dies at the hand of Daemos while giving May and Ben a chance to escape.^[25] In the end of Spider-Geddon, The Other resurrects him.^[26]
• Mary Jane Watson-Parker – Mary Jane Watson-Parker is May and Ben's mother. Sharp-witted and responsible, Mary Jane knows her superhero husband and daughter inside out.
• Phil Urich – Phil is the former Green Goblin (the only hero to use that name in this universe) and a good friend of the Parker family. He has been a friend of the family for so long that May calls him "Uncle Phil." Phil works with Peter Parker at his job in the crime lab. Occasionally, he uses his Goblin powers to help May, at one point taking on the identity of the "Golden Goblin". Later, with the assistance of Norman Osborn, Phil was able to come out of retirement and take on the identity of the Green Goblin again.
• Benjamin Richard Parker – Benjamin is May's beloved little brother, who has shown signs of developing spider-powers despite his young age. Ben was exposed to the Carnage symbiote, which may have sparked the development of his abilities. Ben was briefly rendered deaf due to high-frequency sonics, but eventually recovered. He later gained full-blown spider powers: however, despite Peter's suspicions, no one saw him using his abilities. Ben is affectionately nicknamed "Benjy" by his sister and was named after Uncle Ben and his grandfather Richard Parker.
• April Parker – April is a clone of May Parker, but she is unique in that she is also a Symbiote Hybrid, giving her both the powers of Spider-Girl and Venom. Taking the name "Mayhem", April became a vigilante, and was not above killing criminals; at one point, she tried to end a gang war by killing Black Tarantula, a friend of May's, and she later succeeded in ending the war by killing Hobgoblin. April died saving May from an exploding building, but Peter assures to May that clones always come back, so she may have survived.^[27]

Supporting cast

• Darkdevil – Reilly Tyne is a mocking Puck-like superhero who constantly taunts Spider-Girl for her various weaknesses, but has also proven to be a valuable ally. Although May's cousin (although some could call him her genetic half-brother), people mistook him for the currently-deceased Daredevil.
• Gerry Drew – He's the son of Jessica Drew, the first Spider-Woman. He has spider-powers because of his mother and he has an illness because of her radiation exposure. He once impersonated Spider-Man, but later retires from this alter-ego.
• Courtney Duran – Courtney is May's friend in school. She is a level-headed and bespectacled "Miss Normal" who is in her Science Club, and volunteers in the community along with May.
• Ladyhawk (Rosetta Morgan and Regina Morgan) is the shared codename skilled martial artist sisters that use bird-themed shuriken and other weapons.
• Heather Noble – Heather is one of May's schoolmates. At first, she acted mean and stuck up towards May, but has since become her friend. She has been dating Jimmy Yama. Heather is later kidnapped by the Hobgoblin but fortunately Spider-Girl rescues her.
• Simone Desantos – Introduced in The Amazing Spider-Girl series, Simone seems to have taken Heather's former position as the stuck-up "mean girl" of May's school. Her father Rene turns out to be the head of the Goblin Cult, and this once led to Fury kidnapping Simone.
• Felicity Hardy – Felicity is the daughter of Felicia Hardy and Flash Thompson as well as the younger sister of Gene Thompson. She knows that May is Spider-Girl and adopted the costume of Scarlet Spider when May took a break from superhero business. However, she abandoned it quickly and helps May in her civilian identity.
• Sara Hingle – Sara is a mutant with either telekinetic or atomic powers. She had trouble accepting her gifts until May and Mary Jane talked to her. After seeing May nimbly dodge one of her energy blasts, Sara believes that she is a mutant too. She was recently attacked by the anti-mutant group Humanity First, only to be saved by a pair of anti-human mutants, Impact and Pirouette, who convince her to join their crusade. She later takes on the costumed identity of Nucleus, and battles Spider-Girl. When she discovers that Impact and Pirouette are led by Magneta, she flees the group in terror. Later, she attacks Humanity First's headquarters. Spider-Girl arrives, and manages to talk her down. Magneta then activates a device that sends Sarah's powers out of control, resulting in a huge explosion.
• Jack Jameson – Jack Jameson, also called "JJ", is the grandson of J. Jonah Jameson, and he is secretly the superhero called The Buzz.
• Kaine – Kaine is very protective of Spider-Girl (his niece, and ultimately the source of his redemption). He currently leads a government team of reformed supervillains.
• Davida Kirby – Davida is May's best friend in school and teammate on her basketball team.
• Nancy Lu – Nancy a schoolmate of May who is a mutant with telekinetic powers; she was outed by her classmates, and had to leave the high school. She is an X-Man in-training known as "Push".
• Maurice "Moose" Mansfield – Maurice is a burly footballer who constantly clashes with Jimmy Yama. On a field trip, he witnessed Spider-Girl running out of a toilet in which Courtney had been, and from then on, thought Courtney was Spider-Girl. He has recently moved away to live with his uncle while his father is in the hospital. When he was bonded with the Carnage symbiote, he attempted to use its power to cure his father's cancer. When Spider-Girl used Reverb's sonic weaponry to destroy the symbiote, Moose was enraged that his only chance to help his father was destroyed.
• Brad Miller – Brad is a good-looking, smart teenager and May's secret crush. She dropped him when she found out he had a hatred for mutants.
• Normie Osborn – Normie is the grandson of Norman Osborn and was this universe's Green Goblin until he ceded that role to Phil Urich. He is both a former enemy and former crush of May's. In recent issues, he had obtained the Venom-symbiote for his own use until it died in the final battle against Hobgoblin and the Scriers. After the final battle, he married Brenda Drago (Raptor). He still has feelings for May.
• Eugene "Flash" Thompson – Flash is the coach of the basketball team at May's school. He was once married to Felicia Hardy and had a daughter Felicity and a son Gene with her (see above and below), but is unaware that Felicity tried to be May's partner in the hero business. A noticeable difference between this Flash Thompson and his Earth-616 counterpart is that he never lost his legs, and as a result never became the host of the Venom symbiote.
• Eugene "Gene" Thompson – Gene is the son of Felicia Hardy and Flash Thompson, and the older brother of Felicity Hardy. He was dating May, but broke up with her in The Amazing Spider-Girl #13, citing her constant unreliability. Missing her almost immediately, Gene asked Mayday to return to him, with Mayday agreeing. However, his dominating personality and demands for full commitment have placed a strain on Mayday's personal and social life. After beating up Wes Westin, and revealing that he was the one tagging May's campaign posters, May breaks up with him.
• James "Jimmy" Yama – Jimmy is a nerdy Asian schoolmate of May who is in her Science Club. He has a crush on May, a fact that makes May—who likes Jimmy as a friend, but not more–embarrassed. He has since started dating Heather Noble. He has a cousin named Zane, who happens to be the superhero J2, the son of the Juggernaut.
• Wes Westin – Wes is a talented artist, who has collaborated with Jimmy Yama in producing a Spider-Girl comic. He began a short relationship with Davina Kirby, but Davina begins to suspect his true feelings are for Mayday and encourages him to tell her how he feels.

• Mad Dog Rassitano – Human bounty hunter who uses equipment taken from the super-powered villains he hunts. He has his own TV show.

Villains

• Black Tarantula – Fabian LaMuerto is the current Kingpin of Crime. An honorable villain, he is a recurring foe, occasional ally, and possible love-interest for May.

  • Chesbro – Chesbro is the assistant of the Black Tarantula. He comes to New York to represent his master. Chesbro originally served Fabian's father.
• Dragon King – Carlton T. Hackmutter is a janitor at Midtown High School who came across a Dragon Medallion that transformed him into the Dragon King.
• Hobgoblin – Roderick Kingsley, an old foe of Spider-Man's who now serves as May's archenemy. Fearing that Kingsley would prove too much for May, Peter risked his life and once again became Spider-Man despite his handicap to aid her against him. After losing, Kingsley then tried his hand at other crimes only leading to his death at the hands of Mayhem.
• Killerwatt – Originally a backstage hand during concerts, the man now known as Killerwatt, was often blamed by the performing band for malfunctioning electrical equipment, until he was electrocuted by a sound board. He gained electrical based powers and set out to become a costumed thief, defeating Spider-Girl during their first battle, only to be driven off by Darkdevil. Soon after, Spider-Girl was able to defeat him in later battles.
• Mr. Abnormal – The identity of Mr. Abnormal was unknown. When he had entered a toy company, a plastic vat exploded where he was exposed to its chemicals and ended up gaining elastic-based powers.
• Raptor – Brenda Drago is the daughter of the second Vulture. Spider-Girl later convinced her to give up crime. She is a member of Kaine's superteam of reformed supervillains and was recently married to Normie Osborn.
• Sabreclaw – The son of Wolverine and the half-brother of Wild Thing. He has powers like his father and Sabretooth. He has recently joined the A-Next as a hero.

Prime Earth (Earth-616)

May Parker also existed in the primary Earth-616 timeline in which most Marvel Comics are set.

Mary Jane became pregnant at the beginning of the Clone Saga. Impending fatherhood was one of the main reasons Peter retired as Spider-Man during that story-line, passing the mantle to Ben Reilly. However, at the end of the story, Mary Jane was poisoned by Alison Mongrain, an agent of the Green Goblin, and the baby was stillborn (or seemed to be, as Mongrain took the infant away with her).^[28] The stillbirth of his child, combined with the death of Ben Reilly at the hands of the Green Goblin that same night, prompts Peter to retake the Spider-Man identity.

There were hints during the "Identity Crisis" story-line, one of Tom DeFalco's last story-lines on the title, that Baby May would be returned.^[29] Instead, the subplot was dropped, and a few issues later DeFalco was replaced by Howard Mackie and John Byrne. Under that team, Aunt May was brought back instead.^[30] In a flashback in Spider-Girl #49, an alternative version of this story was presented, with the younger May returned instead of the elder.

However, baby May and her parents were never reunited in Marvel's main continuity. Editors repeatedly stated that the baby died, or at the very least would never be seen again; the child was considered a major factor in the aging of the characters. In Marvel Knights Spider-Man issue #9, Mac Gargan, while speaking of Norman Osborn, states "He kills your unborn child, you kill his son". To date, this is the most conclusive evidence of the infant's fate.

The action in The Amazing Spider-Man #439 (Defalco's last on the title) takes place 1,000 years in the future. Two archaeologists stumble across relics belonging to Spider-Man (such as his web-shooters). They speculate on his career, and discuss other heroes who were inspired by him, Spider-Girl and Spider-Man 2099.

In several interviews at Comic Book Resources following the publication of "One More Day," Joe Quesada mentioned that the Spider-Girl title would be the ideal place for disgruntled readers to follow the development of an aged, married Peter and M.J. as they raise a family.^[31] Quesada's comments were followed by a feature article on Spider-Girl with an interview with Tom Defalco, who acknowledged that Quesada was a fan of the character and the title.^[32] Moreover, during the 'One More Day/Brand New Day' story arc, Peter and Mary Jane have visions of a very young girl with red hair, who, after the deal is made with Mephisto, is revealed to be the daughter they would never have now that the deal is done. Despite this, Quesada has stated that he feels the MC2 universe is the natural progression of the characters.

During the "Sinister War" arc, it is revealed that Mephisto erased the Parkers' marriage to ensure that their daughter does not exist, as she would one day end his eventual reign over the Earth.^[33]

Earth X

There are two variant and alternate universe versions of Spider-Girl. One was raised by a Ben Reilly who survived after her father died during her childhood, as seen What If? vol. 2 #86, and later revealed in the Paradise X: Heralds miniseries. Another version of Spider-Girl is actually Venom, who is seen in the Earth X miniseries and its two sequels, Universe X and Paradise X.

The Venom version of May Parker is later recruited by Kang the Conqueror as part of a scheme against the Apocalypse Twins and the Avengers Unity Squad.^[34]

The world of MC2 is designated as "Earth-982". The world where Spider-Girl was raised by Ben Reilly is known as "Earth-1122" and the world featuring Venom as Spider-Girl along with the other heroes of the Earth X saga is known as "Earth-9997".

Spider-Man: Clone Saga

In 2009, Marvel published a miniseries based on the original plans for the Clone Saga. As in the original Clone Saga, Allison Mongraine kidnaps the infant May after she is born. However, the circumstances are a bit different. Mary Jane and Peter actually get to hold May before she is stolen, and Mongraine later hands the baby over to Kaine (who is working for the Green Goblin in this continuity). Holding the baby in his arms makes Kaine begin to doubt the Goblin's plans. His shadowy boss (later revealed to be Harry Osborn) notes to Kaine "You'll have to kill her if things go wrong."^[35] At the end of the series, Kaine returns May to Peter and Mary Jane.

Spectacular Spider-Girl

In a time-travel arc taking place in the UK-based publication The Spectacular Spider-Man, aimed at a much younger audience, Peter meets a Spider-Girl whilst trailing the Sandman in the future. With the aid of Spider-Girl and H.E.R.B.I.E., Peter defeats the Sandman and returns to his own time with H.E.R.B.I.E. At the conclusion of the strip, Spider-Girl returns home to her parents, revealed as Peter and Mary Jane Parker, and unmasks to reveal the features of Mayday Parker. Mayday tells her parents of her experience with a "new Spider-Man", before Peter assures her that the individual she met was a past version of himself. Peter also reveals in the conversation that, like his MC2 counterpart, he was forced to abandon his career as Spider-Man due to a leg injury. This continuity is separate from both MC2 and 616, making this the second continuity to adapt the MC2 version of how Peter relinquished the Spider-Man identity.

Mayday would again cross paths with her father's past self when Lady Octopus travels back in time to assassinate him. Mayday teams with her father but does not reveal her identity to him, despite desperately wanting to, for fear it may damage the timeline. The two defeat Lady Octopus and Mayday returns to the future.

Swiney-Girl

Tom Defalco briefly returned to his other Marvel creation Spider-Ham, an alternate version of Spider-Man that is a pig, in 2009 and 2010. Within those stories he introduced an alternate version of Spider-Girl known as Swiney-Girl. May "Mayday" Porker has similar background history with Spider-Girl, with her being the daughter of Peter Porker and Mary Crane Watsow, her father losing his leg after the final battle between Norman Osbird/Green Gobbler, and saving her father as Swiney-Girl from the grandson of the Green Gobbler, Norman Osbird Jr.^[36]

Amazing Spider-Man: Renew Your Vows

In this continuity, Peter and Mary Jane have a daughter named Annie May Parker, who eventually becomes the superhero Spiderling. While it was believed she was the world's version of Spider-Girl, it eventually was revealed that the Clone Saga from the 616 continuity still happened in this world, which makes Annie May's younger sister.^[37]

Spider-Man: Life Story

In this continuity, Peter and Mary Jane have twins named Claire and Benjy Parker. Despite having a different name, Claire bears a strong resemblance in both appearance and personality to Mayday. For the first ten years of their lives, the two were solely raised by Mary Jane in Portland, Oregon after she left Peter following a traumatic incident. In 1995, Peter lets Ben Reilly take over his life as Spider-Man and CEO of Parker Industries so he could return to his family. In the mid-2000s, Claire convinces Peter to return to New York and become Spider-Man once more shortly after Morlun kills Ben Reilly so he could stop Tony Stark from taking over Parker Industries and to lure Morlun away from his family. Despite his efforts, Morlun attacks the twins and Mary Jane in Oregon as Peter gets involved in the superhero Civil War. When Benjy discovers that Morlun is vulnerable when he is feeding off someone, he uses himself as bait to allow Claire the chance to impale him on a splintered log of wood. Benjy survives the assault, but is crippled for life. By 2019, Claire has become Spider-Woman (now wearing a costume similar to Ultimate Jessica Drew's), and is instructed by her father to stay behind to protect her brother and mother as he goes to space to end Doctor Doom's reign of terror on the planet with Miles Morales.^[38]
