Well, one possible plot could be that Peter has some sort of special connection with each of the Avengers. Maybe he has a unique power that only activates when he's near them, and they gradually realize he's like a missing piece to their team. They start to protect him and he in turn helps them with his intelligence and quick thinking.
Perhaps the fanfiction could start with Peter being an ordinary kid who gets caught in an Avengers' battle. But instead of being scared, he shows great courage. This catches the Avengers' attention. As time passes, they discover that he's their soulmate in a way that he can understand their unspoken feelings and thoughts. He becomes a crucial part of their team, and they go on adventures, facing various villains and also having some heart - warming moments together.
One option is Pepper Potts. She is intelligent and has a strong will. In a fanfiction, she might see the potential in Peter and they could develop a relationship. Pepper could also help Peter deal with the business side of being a superhero, like Tony Stark did, and they could fall in love over time.
Another possibility is that Peter Parker's soulmate is Natasha Romanoff. She could act as a mentor to him in addition to being his soulmate. Natasha's combat skills and experience would complement Peter's abilities well. They might share a bond that goes beyond the typical superhero relationships, perhaps a connection based on their shared sense of loyalty and duty.
It could be Tony Stark. Since Peter is a brilliant kid and Tony is a genius, they might have a special bond. Tony could see a younger version of himself in Peter and take him under his wing. Their connection could be deeper than just mentorship, like they have a soul - to - soul understanding.
A simple plot could be Wade and Peter going on a solo adventure outside of the main Avengers activities. They stumble upon a hidden lair of a small - time villain who is planning something big. They use their combined skills to infiltrate the lair, with Peter using his web - slinging and agility and Wade using his weapons and combat skills. In the end, they stop the villain's plan and return to the Avengers as heroes.
Well, perhaps Peter is frustrated with the Avengers for not including him in a crucial mission. Maybe he feels overlooked and underestimated, so he yells at them to voice his anger and disappointment.
In this fanfiction, it might be that Peter has been framed for a crime he didn't commit. The Avengers, who are duty - bound to uphold justice, are misled by false evidence. They attack Peter, but as the story progresses, Peter tries to prove his innocence. He might find some allies within the superhero community who believe in him and help him face the Avengers and clear his name.
Perhaps Peter's sickness is a result of his overuse of his powers. The Avengers, especially Tony Stark, feel responsible. They start by quarantining Peter in the Avengers Tower. Then, they call in all their medical and scientific resources. They might discover that the only way to heal him is for Peter to temporarily give up his powers, which would be a huge struggle for him.
Well, without actually reading it, it could be about Peter (presumably Peter Parker, Spider - Man) and his adventures related to the Infinity Stones in an Avengers - centric fanfiction. Maybe he's trying to protect the Stones from villains or help the Avengers use them in some new way.
In this fanfiction, perhaps the rogue Avengers are hiding out when they hear baby Peter crying. They initially think it's a trap but then realize it's just an innocent baby. Some of the Avengers might want to take him with them because they see his potential, while others are more hesitant due to their own precarious situation.
Well, perhaps the plot could involve Peter Parker feeling disillusioned with the main Avengers group for some reason. Maybe he disagrees with their new leadership or a particular decision they made. So, he decides to join the rogue Avengers. They might be on a mission to expose some hidden secrets within the superhero community that the official Avengers are trying to keep under wraps. And Peter, with his unique abilities and sense of justice, could play a crucial role in their operations.
