It could be a way for the author to explore the characters' relationships and emotions in a more extreme way.
It's likely that in this fanfiction, there's a build - up of events that lead to Peter beating up Flash. For example, Flash might have made fun of Peter's abilities or his social status.

Obviously, Peter and Flash. It's possible that Peter is a hero - type character with a moral code that Flash has somehow violated.
