In the fanfic, iruka passed out after the mizuki incident so he doesn't graduate Naruto, due to this Naruto doesn't graduate the academy. After the mizuki incident, it turns out that Naruto accidentally copied the forbidden scroll when he used the shadow clone jutsu against mizuki, this gives Naruto the idea to become as strong as possible as a prank
I mean, why didn't he just use his quirk to remake his body with bones stronger than any other material and his muscles stronger than anyone else's? Theoretically he could turn himself into a literal god of strength and durability with his quirk. Even if you mention he needs the extra mass to do it, he clearly doesn't mind merging his body with other people's.
I don't remember a lot of the fanfic but I do remember that Naruto creates a set of seals including one that increases gravity the more you get close to him and another that allows Naruto to bring back anyone he kills within the area that the seal effects, I'm pretty sure he used it on neji during the third round of the chunin exams.
In this fanfic Naruto graduates a year early and is put on a team with two OC'S and Kakashi, also Naruto is much stronger than in the original universe, eventually they get a mission where they end up getting attacked by a group of rogue Shinobi's and the OC teammates are injured pretty badly. Then the council forces Kakashi to accept two new academy students (Sasuke and Sakura) as the replacement teammates. Also it's a naruhina fanfic
In this fanfic idea a young Naruto one day is trying to awaken his chakra, and he ends up finding it and unlocking his chakra, but strangely he thinks that it feels like a massive amount of wind. He ends up going to Hiruzen who easily recognizes what's going on, Naruto has a extremely powerful Wind affinity, stronger than even the Tobirama's water affinity. Seeing Naruto's potential, Hiruzen gives Naruto some books on chakra control, and affinity training. This leads Naruto down the path of becoming basically a God of wind, starting with him discovering that due to how high his wind affinity is, and how much chakra he has (around the amount of a kage) doing the affinity training is incredibly easy, he finishes the splitting a leaf in half in just a second on his first try, and the water fall exercise within 2 days. Though he decides to get his chakra control perfect before doing more. Luckily for him, his godlike wind affinity helps him with chakra control due to the fact that wind affinity training also increased his chakra control. By the end of the academy Naruto has completely mastered his wind affinity, and made multiple jutsu, and even moves using pure wind manipulation, including a armor of hundreds of thousands of wind blades that will cut anything to shreds that tries to touch him. He's also learned Fire affinity (even though it's nowhere near as powerful as his wind) and learned some fire jutsu so he can do combined attacks.
Also due to his massive amounts of chakra (due to his uzumaki heritage and the Nine-tails) he heals incredibly quickly, so he also does insane physical workouts.
What do you think about this idea? I know that it seems like I'm making a godlike Naruto, but he'll still have a weaknesse to Fire jutsu users because it's the opposite element of wind. Though he'll be around sanin or higher level of power. He'll still have some trouble with join level opponents that use lightning jutsu. Though this is a fanfic Idea where I wouldn't recommend nerfing Naruto's potential in anyway, because then you'll just be making canon with Naruto being slightly better at Elemental manipulation and nobody wants another fanfic like that
I don't remember much but what I do remember is that Two boys (Don't know if they are just strangers, Friends or siblings) Do a ritual where they cut their palms with a Old carpenter's(I believe) knife and shake hands, becoming blood Brothers. But they also gain powers, I believe one of the boys is bullied by other people and ends up becoming evil. The other boy has a hot girlfriend. also I remember that it's not a fully English series
