One common theme is Izuku's growth. Fanfictions often show how he progresses from being a quirkless underdog to a highly respected hero, and other characters praise him for his tenacity and development. For instance, his classmates might admire how he overcomes challenges despite starting with no quirk.
Another place to look is FanFiction.net. They also have a lot of My Hero Academia fanfictions. However, the quality can vary a great deal. You might have to sift through some to find the ones where Izuku is praised in a way that you like. Some of these fanfictions may focus on his heroic deeds and how other characters in the MHA universe praise him for it.
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.
In the 'My Hero Academia Godlike Izuku Fanfiction', Izuku might be special because the author gives him extraordinary intelligence. He could use this intelligence to analyze his opponents' weaknesses much faster and more accurately than in the original story. Also, his leadership skills could be off the charts. He might be able to inspire his classmates and other heroes in a way that no one else can, leading them to victory in battles that would otherwise be lost. This combination of intelligence and leadership, along with his already powerful quirk, could be what makes him godlike.
