Petra Parker better known as Spider-Girl is an alternate Universe counterpart of Spider-Man from the Gender-Flipped Universe.



When "Ultimate Spider-Man" arrives in her dimension, he is surprised to find a female version of J. Jonah Jameson named Joanna Jameson, who like Jonah, slanders superheroes. Spider-man encounters Spider-Girl, who is very surprised and rather angry that there is a male version of her hero identity, constantly telling Peter to stay out of her way, telling him "a boy can't be Spider-Girl". She also disbelieves his story of being her counterpart from another world and attacks him when he tries to insist.

However, Peter gets through to her by using a familiar quote that someone told him that "with great power comes great responsibility", something she heard too. Now believing him, she questions if everything else he said such as him really being her from a parallel world is true, as he confirms it by revealing his secret identity and she does the same. After moving past an awkward moment, where they are both put off by a similar appearance to the other. Peter then warns her of the Green Goblin, who is after her blood. Petra, having faced a "Goblin" before, says she knows where to find them.

As they arrive at Oscorp, Spider-Man is surprised to see a female version of Green Goblin, named Norma Osborn (voiced by Wendie Malick), who is based on the original incarnation, with a costume, bat-glider, and pumpkin bombs, while Spider-Girl is surprised to see a male Green Goblin (voiced by Steven Weber, based on the Ultimate incarnation, who is monstrous and mutated, yet still uses a glider and bombs. She frantically questions if "Goblin is a man or monster", to which Goblin replies "Why can't I be both?". As Spider-Girl fights Green Goblin, while Spider-Man fights She-Goblin. After finding an opening to steal a sample of Spider-Girl's blood, and after doing so, Norma asks Norman to give her what she asked for, which is a vial of the Goblin serum. After drinking it, Norma transforms into a monstrous version of herself, fully becoming She-Goblin. As they battle and defeat her, Spider-Girl runs out of web-fluid and falls off of the Georgia Washington Bridge, but Peter saves her. Having defeated Norma, Petra thanks Peter for helping her, saying "It's good to know there's another hero out there, even if he's a boy." Spider-Man bids Spider-Girl farewell, as he pursues his Goblin.

Spider-Girl returns in "Spider-Verse" Part 4, having been summoned by the "Ultimate" Spider-Man, alongside Spider-Man 2099, Spyder-Knight, Spider-Man Noir, Spider-Ham and Ultimate Spider-Man, forming the Web-Warriors, in order to combat Goblin, who has injected himself with a serum of their DNA, and has transformed into Spider-Goblin. After defeating Spider-Goblin, Electro, who Goblin had been using as a slave throughout the story, is freed from the Siege Perilous, and having been empowered by it, merges with the Helicarrier, transforming into a massive battle mecha. As they fight Electro, he sets the Helicarrier to self-destruct. After Spider-Man defeats Electro, Spider-Girl, with help from Spider-Ham, set the Helicarrier to fly out of reach, where it can detonate safely. With the battle won, Spider-Girl, along with all of the Spider-Men, returns to her dimension

Return to Spiderverse

Spider-Girl reappears in Return to the Spider-Verse: Part 4, where it is revealed that she encountered the evil spiderman Wolf Spider who had drained the life essence of her and her other counterparts.

She was saved by the Ultimate Spiderman and with the other spidermen thank him for getting them their drive back before returning to their respective dimensions.


Much like her male counterpart, Peter Parker, Petra is very confident in her abilities, and constantly delivers witty quips and jokes. She is very talkative, ranting on and on without letting Peter ask a question.

Although her overconfidence tends to get her into trouble, like when she underestimates Peter's version of the Goblin until seeing how dangerous he truly is. She is also very sexist, calling Peter a "boy" in a negative tone, although this may be a result of her native universe, which may be dominated by women.

After she finds out Peter was alternate version of her and had a life similar to hers, she was surprised by this but accepting of him as she had someone who understood her and became friendly with him even motivating him not give up in a fight with a villain. She also became amazed by the fact that there were other worlds, even if her counterparts were males. Petra even befriended the other spidermen from other worlds and worked with them to save the city.

Physical appearance

Petra Parker is a Caucasian teenage girl of average height with a lean frame, sporting muscular and well-defined build, due to the radioactive spider bite. She has brown hair and blue eyes.


Her costume is based on an arachnid, with the spider suit's primary colors being red and blue, with a silhouette of a spider on the chest area and a large red spider on the back. The red has a pattern that resembles that of a spider web, with the center of the web being on the topside of his nose. The red and webs only go to the shoulders on the costume. The eyes on the mask are white with a bold black outline.
