Well, you could write a fanfiction where Peter Parker has to team up with a villain from a different universe who is also trying to get back home. They form an unlikely alliance and during their journey, Peter learns more about the multiverse and his own powers. It would be full of action and character development.
First, think about the aspect of Peter Parker's character or the 'Homecoming' story that you want to focus on. It could be his friendship with Ned, his crush on Liz, or his struggles with being a new superhero. Then, just start with a simple scene, like Peter waking up in the morning and getting ready for school while thinking about his latest Spider - Man adventure.
It could be a new super - villain introduced in the fanfiction. Maybe a villain with powers that are specifically designed to counter Spider - Man's. For instance, a villain who can manipulate technology and uses it to disable Peter's suit and then delivers a fatal blow.
Perhaps in the fanfiction, there is a malfunction in Peter's suit technology. It could be that the suit's power source goes haywire and causes an explosion that kills Peter. This could be due to some sabotage by a new enemy who targets Peter specifically because of his growing reputation as Spider - Man in the Homecoming universe.
Their relationship could be developed differently by having MJ be the one with superpowers instead of Peter. This would completely change the dynamic as Peter would have to deal with being the 'normal' one in the relationship. He might feel a bit of envy at first but then learn to support MJ in her new role.
One plot idea could be Peter and MJ going on a secret date during the Homecoming events. They have to avoid being noticed by their classmates and also any villains that might be lurking around. Another idea is MJ discovers Peter's secret identity in a really unexpected way, like when she accidentally stumbles upon his Spider - Man gear while looking for a book in his room.
One interesting plot idea could be Peter trying to balance his high school life with new, more dangerous threats in Queens that are not related to the big - name villains. Maybe a group of tech - savvy thieves are using stolen Stark tech in creative ways, and Peter has to outwit them without revealing his identity to his classmates. Another idea is exploring Peter's relationship with his teachers in a more in - depth way. For example, a teacher suspects that Peter is up to something unusual and starts to investigate, putting Peter in a tricky situation.
Peter would probably be really stressed at first. He's always been careful about keeping his identity a secret, so having it revealed would be a huge shock. He might feel like he's let down his loved ones by putting them in danger.
I'm not sure specifically about 'peter parker 5 1 fanfiction'. But there are many great Peter Parker fanfictions out there. You can try websites like Archive of Our Own. They have a vast collection of fan - made stories about Peter Parker that are really engaging.
One possibility in fanfiction could be that Peter Parker uses his dancing skills to blend in at a high - society event while on a spying mission for the Avengers. His acrobatic abilities as Spider - Man would translate well into unique dance moves.
