Perhaps in the fanfiction, All Might visits the Naruto universe. Naruto is intrigued by his power and starts to train under him. Together, they face a new threat that combines the dark forces of the Naruto world and some villains from My Hero Academia. The plot could revolve around how they use their combined skills and knowledge to defeat this new enemy.
Well, one possibility could be that Naruto inherits some of All Might's heroic qualities. Maybe he has an in - built sense of justice like All Might. He could use his ninja skills along with the moral compass he got from All Might to protect his village in new and unique ways. For example, he might be more fearless in the face of danger, and inspire others in the ninja world in a similar way All Might inspired in his own universe.
It could be about All Might gently reprimanding one of his students in U.A. High. Maybe a student made a mistake during training, like using their quirk in a dangerous or irresponsible way, and All Might has to correct them in his kind-hearted manner.
One possible reason could be a misunderstanding. Maybe Naruto heard some false rumors about All Might's actions in the hero world that made him form a negative opinion. For example, if there were rumors that All Might was too self - centered in his heroics, Naruto, who values teamwork and selfless acts in his own ninja world, might start to dislike him.
Well, one possibility could be that Naruto discovers he has a special connection to all the clans. Maybe he starts to learn unique jutsus from each clan and uses them to bring peace to the ninja world.
One possible plot could be Naruto suddenly awakening all bloodlines and using them to defeat a new, extremely powerful enemy that threatens the entire ninja world.
One possible plot could be that Naruto becomes an all - powerful ninja who uses his knowledge of all jutsus to bring peace to the ninja world. He could travel from village to village, teaching the jutsus to others and uniting the different ninja clans.
It could be that Mineta was being cowardly during a mock battle. All Might has always emphasized the importance of courage in heroism. Mineta, being his usual timid self in the face of danger, decides to hide or run away instead of facing the 'villain'. All Might, disappointed in his lack of courage, yells at him. He tells Mineta that heroes don't run from challenges and that he needs to find the inner strength to face his fears if he ever wants to be a real hero.
The plot could involve Naruto being haunted by Hashirama's spirit. Hashirama's spirit appears to Naruto during difficult times in his life, like when he's facing tough opponents or making important decisions. Hashirama gives Naruto advice based on his own experiences. As Naruto continues to interact with Hashirama's spirit, he becomes more and more of a 'fan' and starts to model his behavior and beliefs after Hashirama. This could lead to Naruto bringing about a new era of peace in the ninja world, inspired by Hashirama's vision.
One possible plot is that Naruto and Lobo are merged into one being. This new entity has the powers of both Naruto and Lobo. It then goes on a journey to find a way to separate them again while facing various challenges along the way. The story could involve battles against powerful foes who are interested in this new and unique power. There could also be a sub - plot about how Naruto's friends in his original world are trying to find a way to bring him back.
One possible plot could be that Naruto somehow gets transported to the world where Jellal is. He has to adapt to the new magic - based environment using his ninja skills. Maybe he is mistaken for Jellal at first and has to deal with the consequences of that identity mix - up.
