Another character could be Kakashi. As Naruto's teacher, he might have some influence on how Naruto approaches the situation. He could either encourage Naruto to be more diplomatic or, if he also sees the council's wrongdoings, support Naruto in a more direct way. There could also be other ninja characters who are on the sidelines, observing this power struggle between Naruto and the council.
Well, in this kind of fanfiction, Naruto might snap at the council because he's tired of their unfair treatment. Maybe they keep underestimating him or trying to control his actions. For example, they could be restricting his ninja training or missions in a way that he finds unjust.
Obviously, Naruto himself is the central character as it's about him 'snapping'. Sasuke is also often involved. He might be a factor in what causes Naruto to snap, or he could be on the receiving end if Naruto's snapping is directed at his actions or decisions.
Obviously, Naruto would be the main character. But there could also be other characters like Shikamaru, who might be his advisor or right - hand man in dealing with the council matters. Sakura could also be involved, perhaps as a medical ninja representative in the new council structure that Naruto creates.
Obviously Naruto would be one of the main characters. He'd be the one to bridge the gap between the Naruto universe and the Jedi Council. Sasuke could also be a main character, his brooding nature might be an interesting contrast to the calm and collected Jedi. And from the Jedi side, characters like Yoda or Mace Windu could be central, as they are important members of the Jedi Council and would be the ones to interact the most with the Naruto characters.
Obviously Naruto is one of the main characters since the title mentions him. And the rookies are also main characters, though we don't know exactly which rookies without reading it. It could be the ones from his own generation like Sakura, Sasuke, etc., or it could be new rookies that Naruto is mentoring.
In some fanfictions, antagonists can also be important in relation to Naruto's mind snapping. For instance, Orochimaru might be interested in Naruto's new state. He could see it as an opportunity to either use Naruto for his own evil plans or study him to gain some new knowledge. So, the villains can have a significant role in the story of Naruto's mind snap.
The main character is Goku, no doubt. However, Bulma could also be a significant character. She is often involved in the group's adventures and might be the one who discovers what's wrong with Goku when he snaps. Additionally, Whis and Beerus could be important characters in this fanfiction. As deities, they might have insights into Goku's state or even be the ones to try and calm him down if his snapping causes chaos in the universe.
Obviously, Kokichi is one of the main characters since it's in his name. But there could be other characters as well. It might include his friends or rivals from the original source material. For example, if it's related to a game, characters like Shuichi or Kaito could be involved as they interact with Kokichi during his 'snapping' moment.
Summer can also be a main character in Morty Snaps fanfiction. She could be jealous of Morty's power, or she could be involved in the adventures that Morty's snaps create. Maybe she helps Morty figure out how to control his power better or uses his snaps for her own gain in some humorous way.
The main characters are clearly Izuku and Monoma. Izuku, also known as Deku, is the protagonist of the main 'My Hero Academia' series, a kind - hearted but often underestimated boy with a powerful quirk. Monoma, on the other hand, is from a different class in U.A. High School. He has a quirk that allows him to copy others' quirks for a short time. Their interactions, especially when Izuku snaps at Monoma, are the central focus of this fanfiction.
