There could be a deeper reason for the fight in the fanfiction. Maybe Flash has accidentally found out something about Peter's double life and is trying to blackmail him. This would lead to a more intense and emotional fight, with Peter having to protect his secret identity at all costs.
One possible scenario in such a fanfiction could be a school - related incident. Flash taunts Peter in front of everyone, and Peter, tired of it, decides to fight back in a more subtle way. Maybe he uses his super speed and reflexes to dodge Flash's attacks and make Flash look foolish without using full - on Spider - Man powers.
Well, if Peter Parker becomes Flash in fanfiction, he might use his new super - speed in really interesting ways. For example, he could swing between buildings as Spider - Man even faster. Maybe he'd combine his spider - sense with the Flash's ability to see things in slow motion, making him an even more formidable hero. He could also use the Flash's speed to create new web - slinging techniques, like using his speed to make the webs shoot out faster and farther.
In the fanfiction, they might be kidnapped by a supervillain who wants to use them as bait to lure Spider - Man. Maybe the kidnapper thinks Flash has some connection to Peter Parker (aka Spider - Man) and plans to expose his identity through Flash.
One possible reason could be envy. Flash might be jealous of Peter's intelligence or popularity at school. Maybe he feels overshadowed by Peter and his achievements, so in the fanfiction, his anger and frustration lead him to lash out physically.
He could be using his phone to track a villain's movements. Maybe he installed some special app on his phone that can detect unusual energy signatures. So while the teacher is droning on about history or math, Peter is secretly following the path of a super - villain who is on the loose in the city.
If Peter Parker joins the Avengers in fanfiction, it would change the team dynamics significantly. Peter is used to operating on his own in Queens, but with the Avengers, he'd have to learn to work as part of a much larger and more powerful team. He could introduce the Avengers to his street - level knowledge, which might be useful when dealing with villains who operate in the shadows. His relationship with Aunt May could also play a role, as the Avengers might need to protect her from any potential threats. Plus, his growth as a hero would be accelerated by being around such experienced and powerful teammates.
Perhaps Peter Parker gets invited to the White House for some sort of science fair or young innovators' event. There, he meets the president and they strike up an unlikely friendship. The president could then call on Peter for help in situations that require his unique skills, like dealing with a super - villain who has some connection to national security.
Well, Deadpool might crack a lot of jokes and make Peter Parker super confused. He could also try to team up with Peter to fight some villains, but his crazy methods would probably drive Peter nuts.
One scenario could be that the Avengers are facing a new threat that requires Peter's special skills. His ability to stick to walls and his enhanced strength could be crucial. Peter might also introduce a sense of youthful enthusiasm to the group. He could crack jokes during tense situations, which at first annoys some of the Avengers but later they come to appreciate it as a way to lighten the mood.
In a 'Peter Parker meets Loki' fanfiction, they might start as adversaries. Loki could see Peter as a new and interesting target to play his tricks on. Peter, on the other hand, would be initially cautious but also curious about this Asgardian. Maybe Loki would try to use Peter's naivete to his advantage, but Peter's Spider - Sense would keep him on guard. Eventually, they could end up teaming up against a common enemy, like some powerful interdimensional villain.
