There's no way to know for sure without reading the fanfic. It could be about well - known characters from a popular series, or it could be entirely new characters that the author has dreamed up. If it's a fanfic of a specific work, it might feature the protagonists and antagonists from that work in a new and different scenario related to the 'break yourself against my stones' concept.
Since we don't have any information about the fanfic other than its title, we can't determine the main characters. However, if it's in a genre like fantasy or science - fiction, the characters could be a diverse range. Maybe it's a story about a young hero and a powerful, mysterious figure whose'stones' the hero has to break against. Or it could be a group of characters where one is the 'breaker' and the others are associated with the'stones' in some way.
I have no idea who the main characters are as I haven't read it. It could be original characters created by the fanfic author or characters from an existing franchise that the fanfic is based on.
I'm not sure specifically as it could be a very unique fanfic. It might be about a conflict or struggle where one character is pitted against another's'stones' which could be metaphorical for their strength or defenses.
It's hard to say without reading it, but it could be Harry, Hermione, and Ron. Since it's a Harry Potter fanfic, they are often the main characters in many fan - made stories. They might be the ones to discover the stones and their power.
Since I don't know the specific fanfic, I can't say for sure. But usually in a story about a coup against corruption, there could be a leader - type character who initiates the movement. There might also be a sidekick or a group of rebels who support this leader.
I'm not sure as I haven't read the specific 'Stones of Power' Harry Potter fanfic. But it could be Harry, Hermione, and Ron as they are the main characters in the original series and often play central roles in fanfics too. They might be on a quest to find or protect the Stones of Power.
Since it's a Naruto crossover, Naruto himself is likely to be one of the main characters. There might also be other well - known Naruto characters like Sasuke or Sakura. As for the crossover part, it depends on what it's crossed with. If it's a Bleach crossover, Ichigo might be a main character too.
Since I haven't read the fanfic, it's hard to say. But typically, in a nemesis - themed story, there would be two main characters who are in opposition to each other. They could be heroes and villains from an existing franchise that the fanfic is based on.
I don't know as I haven't read it, but they could be characters involved in a complex love story.
I'm not sure exactly, but there could be brave adventurers.
I don't know who the main characters are in the 'stones short story' as I haven't read it. But they could be a young adventurer who discovers the stones, or an old storyteller who knows the secrets of the stones.
I'm sorry, as I don't know the 'the stones short story', I can't say for sure who the main characters are. They could be ordinary people like a farmer or a shepherd who stumbles upon the stones, or perhaps some adventurers looking for something unique.
