I do not own any characters used by Marvel. This is a work of fiction, and should not be counted as canon. All character rights belong to Marvel Comics.
This story follows Peter Parker, set in the same universe as the MCU, with a few exceptions. The exceptions are that the Netflix series, and The First Two Fantastic Four movies all coincide with each other. In this Universe, Homecoming took place right after Age of Ultron. Peter Parker is 20 years old and works for Dr. Conner's. This Story takes place after the End of Avengers: Infinity War, this will follow Infinity War with a few exceptions. Please Enjoy.
Thanos looks up at Thor and smiles, "You should have aimed for the head". He raises his gauntlet and a loud metallic snap is heard. Thor looks at Thanos, "What did you do...WHAT DID YOU DO". Thanos disappears and the axe falls to the ground. Bucky walks towards Steve before collapsing into a pile of dust. The same goes for Falcon, Black Panther, and Groot. Meanwhile in New York, Reed Richards is helping contain the problems with the city the best as he can. He looks over at Ben and Luke Cage who are helping lift up rubble to get the trapped citizens out. He sees Ben hunch over and watches in horror as he crumbles, literally, and Luke strains to keep the rubble lifted. Daredevil falls to the ground and is blown away by the wind. Jonny falls out the sky and is nowhere to be found. Reed looks around as he sees countless citizens being turned into dust. Susan holds her hand up as it turns into dust. She reaches for Richard but she is blown away as well. Meanwhile on Titan, Peter clutches his side, his spider senses going off all around him. He looks up at Stark and closes his eyes tightly. Strange stands next to Peter and sees him starting to disappear. He mutters an incantation and a purplish portal appears. He shoves Peter through the portal and then shuts it as he fades to dust as well.
Peter opens his eyes as starts to fall through the portal, he can't scream all he can do is fall. He falls for what seems like forever, suddenly there is a blinding white light, Peter covers his eyes. He opens them to see a building below him, he raise his hands and uses his web shooter to shoot a strand of web at another building. He barely avoids hitting the building and safely swings over to another building. He takes a deep breath and looks around, he is in New York, but it's not his New York. Everything seems a bit off, He leans against the wall and takes a deep breath. He jumps when his Iron Spider suit beeps at him letting him know that the Nano-bots are at critical level. He hits the Spider emblem on his chest and the Nano-bots retreat back into a small box, revealing his spandex suit, which is torn and dirty. There is a large gash tearing through the shoulder part of his suit, and one of his boots is torn. He finds his mask and lets out a groan seeing that it is basically ripped in half, it would only cover his eyes and part of his nose when he tried it on. He ties it up in the back and sighs, "Well this will have to do for now". He swings down to the ground and sees an old gray jacket laying on the ground. He puts it on, and looks around some more. He finds a torn pair of jeans and he slips them over his torn spandex. He walks down an alley way and onto a main sidewalk, he looks around as people push past him. He watches as three police cars go flying past him down the street. He watches them turn the corner and then he sees it, someone using a web slinger. The other web slinger chases after the police cars and rounds the corner as well.
Peter runs back down the alley way and climbs up the wall quickly, he reaches the rooftop and chases after the police cars and the other web slinger. He sings through an alleyway and lands on a nearby rooftop. He watches as the web slinger lands on the ground and confronts the villains. Peter gets closer to the edge and sees that the guy is dressed in a green suit. He sneaks down and gets behind the bad guys in order to flank them. The guy in Green yells an insult, Peter sees his chance. He jumps up and shoots webbing at Green suit, pinning him to the ground. He then turns and kicks the other guy to the ground. The other web slinger seems to be startled, they look at Peter and then turn around quickly when the police appear. They shoot a web and swing away leaving Peter alone. Peter finishes off the last reaming guy when he hears a click behind his head. He slowly raises his hands and turns around.
