Given the title, Peter is likely one of the main characters. But without reading it, it's hard to say for sure who else. It could potentially include characters from Peter's usual storylines like Mary Jane, Aunt May, or his friends. There might also be other Marvel characters involved, like the Avengers, depending on how the story is set up and what kind of world - building the author has done.
Peter is surely a main character in this fanfiction. Other potential main characters could be characters related to Peter's origin story. But it also might include characters like Thor if the story is about the gauntlet's power and how it interacts with different forms of power in the Marvel universe. There could be a whole host of characters from the X - Men universe if the author decides to do a crossover. And let's not forget characters like Nick Fury who could be involved in guiding or observing Peter as he deals with the power of the gauntlet.
Since I haven't read this fanfiction, it's hard to say exactly. However, if Peter snaps the gauntlet, it could potentially change the whole fabric of the fictional universe it's set in. Maybe it's a story that focuses on the aftermath of Peter's snap. The power of the gauntlet could transform him physically or mentally. He might gain new abilities or face new enemies who are attracted by the power he now wields. It could also explore the moral implications of his actions, like whether he uses the power for good or is tempted by the darker aspects of it.
Well, clearly Peter Parker and Tony Stark are the main characters. Peter is the one who 'snaps' in this scenario, which means he has a significant character shift from his normal self. Tony, on the other hand, serves as a sort of contrast or the catalyst for Peter's snapping. Even though Peter is the one with the new behavior, Tony's presence and actions are likely to be integral to the story as they are what cause Peter to 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.
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.
Obviously, Gohan would be one of the main characters since it's about him snapping. And likely, his family members like Goku and Chi - Chi could be important as they might be related to the events that lead to his snapping or be affected by it.
Obviously, Natsu and Erza are the main characters. Natsu is known for his hot - headed and impulsive nature, which could lead to him snapping. Erza, on the other hand, is often strong - willed and in a position of authority, which might be a contributing factor to Natsu's reaction towards her.
Obviously, Percy would be one of the main characters. He is the one who snaps at the gods, so the whole story likely revolves around him. Annabeth could also be a main character as she is Percy's close friend and would likely be involved in his plans or at least support him in some way. Grover might be there too, as he has always been by Percy's side in many adventures.
