Peter Parker (Earth-237)

Becoming Spider-Man
Peter Parker, attempting to prove himself as something more than just a geek, began to learn to wrestle. While he was failing at first, he was bit by a radiated spider at a science fair. While he thought of it as nothing at first, he found his wrestling abilities begin to increase. Becoming a star, he was targeted by the criminal Dennis Carradine, who accidentally shot his uncle Ben in the act. Vowing to avenge his father, he would let his wrestling career fade, instead becoming the vigilante Spider-Man.

The Spider-Initiative
Spider-Man first crossed paths with the Black Cat whenever Doctor Octopus attempted to rob a museum. While he fought with both, they bonded over trying to stop Doctor Octopus (though in reality, Black Cat was only interested because he had the antique she was trying to get). However, whenever the Scorpion started terrorizing New York City, the two would team up to stop him.

At the same time, The Avengers were dealing with Ultron's outbreak. Spider-Woman was split off from the group and helped Spider-Man and Black Cat deal with the Scorpion. They regrouped with the Avengers and took down Ultron. While Spider-Woman initially planned to infiltrate Latveria alone, the two were requested to join her, and the three agreed to form the Spider-Initiative.

Whenever a battle on a space ship between Skrulls and Kree entered Earth's atmosphere, the trio were beamed up onto the ship and requested to help the Skrulls. While they succeeded in driving the Kree off, the ship had been badly damaged and crash landed in Los Angeles, where the Runaways would discover it. After fending off yet another outbreak from Ultron, Nico Minoru's assistance would find her an honorary place in the Spider-Initiative.

Secret Wars
The Spider-Initiative, joined by the Runaways, the Avengers, and the Fantastic Four, were all pulled to Battleworld by the Beyonder, joined by all the villains they had previously faced. There, Spider-Man gained the symbiote suit, and the villain Klaw was created by Dr. Doom and Ultron. After a battle that appeared to be in the favour of the villains, the Beyonder revealed himself and asked that they all help him get Galactus from his planet. The Fantastic Four, with Spider-Man's help, got rid of Galactus.

On their return to Earth, it turned out that Doctor Octopus, The Scorpion, Sandman, Vulture, Kraven, and Shocker had banded together as The Sinister Six and captured reporter Eddie Brock. The symbiote was removed from Peter by Reed Richards when they found out that it was attempting to take control of his body, and the Sinister Six got a hold of it, forcing it onto Eddie and creating Venom. With the consent of Doctor Doom, Klaw removed the Venom symbiote from Eddie using sound. There was one condition, however - the Black Cat would have to join Doom and live in Latveria. They freed her only a few weeks later.

Meeting Gwen Stacy
Gwen Stacy joined the Daily Bugle, Peter's day job, as a secretary.. While he began to form a relationship with her, his boss J. Jonah Jameson sent him out to take pictures. He managed to set up a date with her eventually, where he found out that Norman Osborn had fallen delirious, and learned that he had become the Green Goblin.

While he succeeded in defeating Green Goblin, Kingpin managed to take him down easily, and almost killed J. Jonah Jameson in the process. The Daily Bugle chief would launch a political campaign against Spider-Man in response, convincing Peter to give up the mantle of Spider-Man. However, the Spider-Initiative convinced him to stay a superhero.

After dealing with multiple threats, including the Vulture bonded with Venom, the Spider-Slayers, and the Sentinels, Peter finally had a chance to go on another date with Gwen. They went to see a magic show hosted by Mysterio and Spot, where volunteers from the audience, including Gwen, would be kidnapped. An impromptu battle led to him finding out that the Sinister Six had caused it.

He would face off against Venom once more, joined by a second host of the symbiote, Adamant, who would be recruited into the Spider-Initiative. There he met Venom's offspring, Carnage and Shriek, as well as the Demogoblin, Carrion, and the failed clone of Peter, Doppelganger. With the help of Venom, the Avengers, and the Fantastic Four, the Spider-Initiative successfully defeated these foes.

The Green Goblin, learning of Peter's secret identity, would capture Gwen Stacy and hold her hostage at Brooklyn Bridge. A fight over her life took place, and Peter won, saving her while the Green Goblin plummeted to his seeming demise. On the bridge, Peter revealed his identity to Gwen, and told her his story.
