It might mean that in the world of fanfiction, there's a character named Harry who has been the subject of many stories where he experiences abuse. And the person making this statement feels that there's been an overabundance of such stories. This could be because the abuse aspect is being used too frequently for shock value or is just not in line with how they view the character. It could also be that the writer of the fanfiction is trying to explore a dark side of the character but has overdone it, leading to this sentiment.
It could mean that Harry, perhaps a character named Harry (like Harry Potter), has a sufficient amount of fan - created fictional works about him. There are so many fanfictions written about popular characters, and it might be a statement indicating that the quantity for this 'Harry' has reached a point where it's considered enough.
It could mean that Harry, perhaps a character named Harry, has reached a point where he has had an excessive amount of fan - created fictional works about him. Maybe he's tired of the various interpretations, plotlines, or simply the overabundance of fanfiction that exists regarding him.
It could mean that the Harry Potter franchise has been the subject of so much fan fiction that it's perhaps reached a saturation point. There are countless fan - made stories, and maybe it's felt that there's just too much out there now.
It could mean that someone has had enough of Harry Potter fan fiction. Maybe they've read so much of it that they're tired of it, or perhaps they've come across some aspects of the fanfic that they don't like, like poor writing, out - of - character portrayals, or overused plot lines.
In my opinion, 'naruto has had enough fanfiction' may mean that the Naruto series has been subject to an overabundance of fan - made fictional works. Fanfiction can be great, but when there are too many, it can start to feel like the original Naruto concept is being drowned out. There could also be a sense that the creativity in fanfiction has become repetitive or is going in directions that don't really fit with the core of Naruto.
Well, it could also be that the person making this statement is tired of seeing Hermione in fanfiction in general. Maybe they prefer to focus on the original source material and feel that the fan - made stories about her have detracted from the original essence of the character. They might think that the fanfiction world has exploited her character enough.
Perhaps it means that Naruto has reached a point where he's sick of the various fanfiction scenarios involving Team 7. Fanfiction can range from alternate universes to different relationship dynamics within the team. If there's an overabundance of a particular type of story, like ones that always make Naruto the underdog in a way he doesn't see himself, he might feel like he's had enough.
Maybe they are a fan of Harry (from whatever fandom he belongs to) and they are tired of seeing him being abused in fan - made stories. They might prefer more positive or different storylines for the character.
It could mean that Tony Stark, as a character, has been the subject of so much fanfiction that it's become overwhelming. Maybe the creators or the official side feel that there are too many unregulated or inaccurate portrayals in fan - made stories.
Maybe he's tired of seeing so many different and often inconsistent interpretations of his character in fanfiction.
