I'm not sure about a specific 'ron punched harry fanfic' off the top of my head. You could try searching on fanfic websites like Archive of Our Own. They have a large collection of Harry Potter fanfictions and you might be able to find one with that plot there.
It could also lead to a divide within their group of friends. Hermione, for instance, might be caught in the middle, not knowing who to side with. This could create a lot of tension and conflict among the characters, adding more drama to the fanfic. If the punch was public, it could also damage Ron's reputation among their peers, as punching a friend is not an acceptable behavior in most cases.
Another possibility is that in the fanfic's unique plot, there could be some sort of magical influence or dark magic at play. Perhaps a spell was cast on Ron that made him act out of character and punch Harry. It could also be part of a complex plot where Ron is being controlled by an outside force to create drama between him and Harry in the context of the Drarry relationship.
It could be a misunderstanding. For example, Ron might think Harry did something really bad to Hermione or their other friends. Without proper communication, his anger could lead him to punch Harry. Also, if there was some sort of magical influence or dark magic at play that affected Ron's judgment, that could be a reason too.
One popular 'Overprotective Ron of Harry Fanfic' could be 'Ron's Vigilant Watch'. In this fic, Ron is always on guard to protect Harry from various threats, whether it's from dark wizards or just the everyday bullies at Hogwarts. His overprotective nature is shown through his actions like always being by Harry's side during dangerous situations and constantly warning him about potential perils.
Well, 'Ron and Harry: A Different Perspective' is worth checking out. It presents their story from the point of view of a minor character in the Hogwarts world, which gives a fresh and unique take on their friendship and the events they go through.
Well, 'A Marauder's Plan' is an interesting fanfic. It involves the trio in a plot that has elements related to the Marauders. The author does a great job of writing the interactions between Harry, Hermione, and Ron. They feel very much in - character, and the story has some exciting twists and turns that keep you hooked.
I also like 'Ron and Harry: A Different Kind of Magic'. It shows how their relationship evolves over time, with a lot of focus on their mutual understanding and the little things they do for each other that strengthen their bond.
One great 'Harry Ron bromance fanfic' is 'The Bond Beyond Magic'. It really delves into their deep friendship, showing how they support each other through tough times at Hogwarts. It has some really heartwarming scenes where they share their secrets and fears.
He could become more isolated. After being punched, his friends might avoid him for a while. For example, if Harry punches him, Harry might need some time to cool off and not want to be around Ron. This would make Ron feel really lonely and regret his actions that led to the betrayal.
A cool plotline could be that they discover a time - traveling spell that was forgotten. They use it to go back in time to the founders' era of Hogwarts. There, they have to figure out how to blend in and also learn secrets about the four founders that could change the present - day Hogwarts.
