A common plot in such fanfiction is Spiderman getting involved in a time - travel related harem. He might travel back in time and end up in a relationship with Peggy Carter while also maintaining his connection with the present - day Avengers.

Also, there could be a storyline where Spiderman is part of a harem with the female versions of some of the Avengers from an alternate universe. They come to his universe to seek his help, and along the way, romantic relationships develop.
Some stories focus on the character development within the harem. For instance, Spiderman could start a relationship with Captain Marvel. She is a powerful and independent character, and their relationship could be about mutual growth and respect. Then, as the story progresses, he might also get closer to Gamora. Gamora's complex past and her own set of values add depth to the harem dynamic.

Well, perhaps Spiderman is poisoned by a new type of toxin from a villain. The Avengers then scramble to find an antidote. Black Widow uses her espionage skills to track down the origin of the toxin, while Hulk, in his Banner form, tries to analyze it scientifically. Thor might also use his Asgardian knowledge to see if there are any magical cures. In the meantime, they keep Spiderman comfortable and safe from further attacks.
Perhaps a fanfiction could explore what would happen if Spiderman was the one to first discover a major flaw in Ultron's plan. Since he's a street - level hero with a different perspective from the more global - minded Avengers, he might see something that they miss. His attempts to convince the Avengers about this flaw could create a lot of drama and action in the story.
Perhaps there's a power - stealing device in the fanfiction. It's stolen by a villain and used on the Avengers, but Gwen is immune.

Or perhaps Captain America has to use his old - fashioned parenting skills to take care of the diaper - wearing Avenger. It's a really interesting concept that combines the superhero world with the chaos of baby - hood.
