I'm not sure of specific 'izuku snaps at aizawa fanfiction' titles off the top of my head. You could try searching on fanfiction platforms like Archive of Our Own. They usually have a wide variety of fanfics, and you can use those keywords in the search bar to find relevant stories.
One reason could be that Izuku has been pushed to his limit. Maybe Aizawa has been overly critical or strict in a way that Izuku can't take anymore. For example, if Aizawa constantly doubts Izuku's abilities despite his efforts, it could lead to Izuku snapping.
I really like the fanfic 'Izuku: The Quirkless Hero'. In this story, Izuku forms a special bond with some of the underdog characters. They work together to create a new style of heroics that doesn't rely on quirks. It also explores his relationship with All Might in a different light, as All Might becomes more of a mentor in non - quirk - related areas.
Another emotional moment is when Izuku is on the verge of giving up but is inspired by his friends or a memory of his hero, All Might. His internal struggle and the subsequent renewal of his determination is a powerful emotional arc. It shows his growth and the strength of his character, and it can really tug at the heartstrings of the readers.
One great aspect of Izuku and Jirou fanfiction is the exploration of their different quirks. Izuku's One For All and Jirou's Earphone Jack can lead to really interesting team - up scenarios. Writers often create unique storylines where they face challenges together, like a new villain in town that requires both their skills to defeat.
I really liked 'Gamer Izuku's Ascent'. In this fanfiction, Izuku starts with his gamer skills and slowly builds his reputation as a hero. It shows how he uses his unique skills to outwit villains and make friends along the way. There are some really cool action scenes and character developments.
One possible story could be Izuku proving himself in combat training without a quirk. He could use his intelligence and strategic thinking to outwit his classmates with quirks. For example, he might study their weaknesses in advance and set up elaborate traps during the training exercises.
In many fanfictions, Izuku and the Hero Killer have a complex relationship. Sometimes, Izuku might be portrayed as trying to understand the Hero Killer's motives, which are often misconstrued but rooted in a desire for 'true' heroism. This can lead to some really interesting character development for Izuku as he grapples with his own ideas of heroism in the face of such a radical view.
For Aizawa, it's important to capture his no - nonsense attitude. He's strict with students but also deeply cares about their growth. When writing him in a fanfiction, show his dry sense of humor and his dedication to his job. For Emi, emphasize her bubbly personality and her enthusiasm for teaching. She's always looking for ways to make learning fun for the students.
