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 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.
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.
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.
There could be Peter's best friend. Maybe his friend has been encouraging Peter to stand up to Flash all this time. When Peter finally does it, his friend is right there by his side, supporting him.
In this fanfiction, Peter might stand up to Flash by using his intelligence. For example, if Flash tries to humiliate Peter in class, Peter could outwit him with his knowledge, showing that he's not someone to be pushed around. He could also gain the respect of his classmates in the process, which would be a big blow to Flash's ego.
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, it could be a fanfiction where Peter snaps at Flash. Maybe Flash has been irritating Peter in some way, like constantly teasing him, and Peter finally reaches his limit and snaps. It might involve a situation at school or during some superhero - related events if it's set in a superhero universe.
The main characters are Peter and Flash. Peter is often depicted as the underdog, a smart but sometimes shy guy. He might be a bit of an outcast in school. Flash, on the other hand, is usually the popular jock. He's cocky and likes to show off, often picking on Peter. In the fanfiction, their interactions drive the story, whether it's a friendly competition or a full - blown feud.
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.
