The plot might involve Spiderman getting into some trouble and the three Avengers coming to his rescue. Then they realize there's a much bigger threat looming. They start training Spiderman to be even better at fighting and together they face the threat. It could be a story of growth for Spiderman as he learns from the more experienced Avengers.
Well, it could be about Spiderman teaming up with the three Avengers to fight a new super - villain. Maybe they have to stop a powerful alien from taking over the earth. Spiderman's agility and quick thinking combined with the Avengers' unique powers would make for an exciting story.
Well, one possible plot could be that during a big battle where the Avengers and Spiderman are fighting side by side against a powerful enemy like Thanos. Spiderman, being young and perhaps a bit over - eager, jumps into a dangerous situation without proper backup. He gets injured while trying to protect an Avenger, say Captain America. This could lead to a lot of guilt among the Avengers for not being able to protect him better and also Spiderman having to deal with his own physical and mental recovery.
The three Avengers could be Iron Man, Captain America and Thor. Iron Man could provide the high - tech gadgets and strategic thinking. Captain America would bring leadership and his combat skills. Thor with his godly powers like lightning and super strength would be a great addition. They would each have different interactions with Spiderman, for example, Iron Man might be like a mentor to him, while Thor could be more of a friendly rival in terms of strength.
Perhaps the Avengers are under some sort of mind - control spell. Spiderman, being immune to the spell for some reason, has to figure out how to break it. He might swing around, avoiding attacks from his brainwashed friends, and then find a way to disrupt the source of the mind - control. For example, he could web up a device that was emitting the mind - controlling waves.
A possible plot twist could be that Spiderman is actually from an alternate dimension where he has different powers. And these powers are the key to saving the Avengers. For example, he might be able to time - travel in this dimension and go back to prevent the event that put the Avengers in danger in the first place.
One interesting plot could be Spider - Man having to prove himself to the Avengers. Maybe he starts as an outsider, but through his unique skills like web - slinging and his spider - sense, he helps the Avengers in a mission that they initially thought was impossible. For example, infiltrating a high - security enemy base that is full of high - tech traps.
One plot idea could be that the Avengers discover Spiderman's identity during a mission when his mask gets damaged. Then they have to protect his secret from villains who are also after it.
Well, a cool plot could involve Spider - Man's identity being revealed to the public and the Avengers having to protect him from various villains who see this as an opportunity to take him out. Or perhaps a situation where an old enemy of the Avengers teams up with one of Spider - Man's foes, forcing the two groups to work together more closely than ever. Spider - Man could also introduce some new tech or fighting styles to the Avengers during their joint adventures.
One idea could be that Spiderman discovers a new threat in his neighborhood which turns out to be linked to a much larger plot involving the Avengers. So he has to convince the Avengers to take him seriously and work together to stop it.
It depends on the type of fanfiction. In some darker or more angst - filled fanfictions, it is quite common as it adds drama. However, in more positive or team - building - focused fanfictions, it's not as common. These types of stories usually focus on the Avengers and Spiderman working together and getting along. So, it varies from one type of fanfic to another.
