One popular overpowered Izuku fanfiction is 'One for All: Unlimited'. In this, Izuku has an extreme version of One for All that gives him near - godlike powers right from the start. He's able to take on villains with ease that would normally be a huge threat in the canon story.
Some fanfictions make Izuku overpowered by enhancing the nature of One for All itself. Maybe it gives him unlimited stamina or the ability to share his power with others in a much more efficient way. This changes the power dynamic and makes him far more powerful than in the original story. He could then train a group of heroes to have similar levels of power, making him a key figure in a new kind of hero society.
In some overpowered fanfiction, a character could have the ability to instantly copy and enhance any quirk they come across. So if they see someone with a strength - based quirk, they can not only copy it but make it much stronger. This would lead to some epic battles and power - growth storylines.
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.
