In the fanfiction world, 'Early One for All's Impact' is quite interesting. In this story, Izuku getting One for All early completely changes the power balance in the hero world. Since he has the power earlier, he starts training in different ways and with different mentors. This leads to some unique power developments and fight scenes. Additionally, 'Rapid Inheritance' is another fanfic where his early inheritance of One for All leads to a rift between him and Bakugo initially as Bakugo is jealous and confused about Izuku's sudden power boost.
Well, there's a fanfic called 'Early One for All'. It shows Izuku getting One for All in his early days at U.A. High. The story dives deep into how he has to hide this new power from some villains who are already targeting him because they sense the change in the power dynamics. It's really exciting as it adds a new layer of danger and secrecy to his character arc. There's also 'Swift Inheritance' where the early gain of One for All makes Izuku question his own worthiness more intensely as he feels he hasn't proven himself enough yet.
It changes the power progression. Izuku gets stronger faster, which can lead to different battles. For example, he might face tougher enemies earlier.
Well, one possible plotline could be Izuku's struggle to control the sudden influx of power from One For All at an earlier stage than in the original story. He might face challenges in keeping it a secret from his classmates and teachers, adding a layer of secrecy and tension.
One great 'All for One Izuku fanfic' could be the one where Izuku uses All for One's power in unique ways to fight against the traditional hero system. He might start by secretly training and developing his newfound abilities.
One interesting story could be about Izuku exploring new powers of One For All in a different dimension. He might face challenges that test his limits and how he uses the power in unique ways.
One interesting fanfiction could be where Izuku uses the combination of All for One and One for All in unique ways to defeat powerful villains.

Obviously, Izuku Midoriya is the main character as he is the one mastering One For All early. Katsuki Bakugo might also be prominently involved. Since he has a long - standing rivalry with Izuku, his reaction to Izuku getting such a powerful quirk early on could be a major part of the story. Maybe he feels jealous or challenged in a new way.
One consequence could be a faster growth in Izuku's power. With All Might's early guidance, Izuku may master his Quirk more quickly. Another is that his relationships with other characters might change. For example, Bakugo could become more jealous or, on the contrary, might be inspired to work harder.
In many BNHA fanfictions where Izuku meets All Might early, it often changes the entire trajectory of Izuku's development. For example, he might gain confidence much sooner. Early meetings can also lead to a more in - depth mentorship that might deviate from the original storyline. This could result in Izuku getting special training earlier and potentially unlocking his Quirk in a different way.
In some fanfictions, Katsuki gets One for All and it completely changes his relationship with Deku. Instead of rivalry, they start to train together more closely. There are also fanfictions where Katsuki uses One for All to save the day in a situation where no one else could. For example, when facing a powerful new villain that the other heroes can't handle. He might combine his natural combat skills with the power of One for All in a unique way.
