In this fanfiction, it's possible that a symbiote - influenced villain could be the antagonist. Maybe someone who has bonded with a part of the symbiote and has a thirst for chaos. They might see Flash as an easy target to cause mayhem and draw out Spider - Man. Additionally, the Scorpion could be another antagonist. He might be hired by some shadowy figure to capture Flash in order to lure Spider - Man into a trap. There could also be a group of alien invaders who mistake Flash for someone important and Peter has to save him from their clutches.
Well, perhaps Flash gets into some sort of trouble like being kidnapped by a group of villains who want to use him as a bait to lure Spider - Man (Peter Parker). Peter, using his spidey - senses, tracks Flash down and has to fight off the bad guys to save him. It could also be that Flash accidentally stumbles upon a dangerous experiment and Peter has to save him from the resulting chaos.
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.
One possible story could be that in the fanfiction, Flash's bullying of Peter Parker is a way to show his own insecurities. Flash might bully Peter because Peter is intelligent and seems to get more attention from the teachers, making Flash jealous. For example, Flash could constantly make fun of Peter's nerdy appearance and his love for science, but little does he know that Peter is actually Spider - Man.
Matt Murdock was just going about his day in the city when he sensed something was wrong. His radar - sense led him to an alley where Peter Parker was in a tight spot. Peter had been caught off - guard by some thugs who had a new kind of weapon that could disrupt his spider - sense. Matt, being the fearless Daredevil, didn't hesitate. He charged in, his red - tinted glasses glinting in the dim light. He fought with a ferocity that surprised the thugs. Peter, seeing his chance, regained his composure and joined Matt. They worked as a team, with Matt's acrobatic fighting style complementing Peter's web - slinging abilities, and they defeated the thugs, Peter grateful for Matt's timely rescue.
Well, Mary Jane might be in it. She could be in danger at some point, which gives Peter an extra motivation to save the city. And of course, there could be some new characters created just for this fanfiction, like a young inventor who teams up with Peter to defeat the bad guys. There might also be some villains from the Spider - Man universe, like the Green Goblin or Doctor Octopus.
Well, maybe Peter has to face a new super - villain who has a strange power to control technology. So he swings around the city, using his spider - sense to figure out the villain's plan and then saves the day.
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.
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.
Since Peter is Spider - Man, he has to be careful not to use his powers and reveal his identity. So he might just try to defend himself in a non - superhuman way, like using his quick reflexes to dodge Flash's blows as much as possible while trying to calm Flash down verbally.
