In some fanfiction scenarios, Flash could be under the influence of an outside force. Maybe he has been bullied by someone else who is using him to target Peter. Or he could be affected by a strange power or substance that makes him act out of character and attack Peter.
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.
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.
Well, it could be about a scenario where Peter (presumably from some fictional universe) gets into a physical altercation with Flash. Maybe in this fanfiction, Peter has been pushed to his limits by Flash's actions or words, so he decides to beat him up. It could be a way for the author to explore the characters' relationships and emotions in a more extreme way.
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.
One reason could be for added mobility. Wings would allow Peter Parker to move in different ways compared to just swinging on webs. He could fly over obstacles more easily and reach places quicker. Another reason might be for a new look or aesthetic in the story. It gives the character a different visual appeal.
The danger that comes with being Spider - Man also makes Peter a loner in fanfiction. He doesn't want to put anyone he cares about in harm's way. So he keeps his distance from friends and potential love interests. He might not join group activities or go on dates to protect others, which makes him seem like a loner.
Obviously, Peter and Flash. It's possible that Peter is a hero - type character with a moral code that Flash has somehow violated. Flash could be a sidekick - turned - antagonist or just a regular character who has a conflict with Peter. Their personalities and the nature of their relationship in the original source material would be twisted in this fanfiction to lead to Peter beating up Flash.
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.
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, 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.
