Well, in a fanfiction scenario where Naruto saves Sakumo, it could be that Naruto has mastered some new jutsu that allows him to enter into Sakumo's mind. Sakumo was in a very dark place after being shamed by the village. Naruto could use this jutsu to show Sakumo that there is still hope and that his worth is not defined by the village's opinion. Then he could bring Sakumo back to a positive state of mind and save him from self - destruction.
He might face powerful enemies. For example, if the enemies are from a secret organization with strong and unknown jutsu, Naruto would have to quickly figure out their weaknesses. This could be difficult as he has no prior knowledge of them.
One possible plotline could be that Sakumo is in a dangerous mission situation where he is outnumbered and on the verge of defeat. Naruto, with his powerful jutsu and never - give - up attitude, arrives just in time. He uses his Rasengan to take out the main threats and then uses his shadow clones to rescue Sakumo from the surrounding enemies.
One possible plot twist could be that Sakumo's training methods are very unorthodox compared to what Naruto is used to in the village. For example, he might focus more on stealth and assassination skills which Naruto initially struggles with as he is more used to head - on combat. Another twist could be that Sakumo has a hidden agenda for training Naruto, like he is preparing Naruto for a specific threat that he foresees but hasn't shared with the village yet.
The story in 'naruto trained by sakumo hatake fanfic' could be full of surprises. Sakumo could introduce Naruto to some of his old comrades or tell him stories about the early days of Konoha. This would give Naruto a deeper understanding of the village's history. And with Sakumo's training, Naruto might become even more powerful than in the original series. He could develop new strategies for fighting enemies like Akatsuki, and his relationship with other characters in Konoha might also change as a result of this new training.
His training would likely incorporate more swordplay. Since Sakumo was a master swordsman, Naruto would probably start training with swords at an earlier stage. He might also be taught some of Sakumo's signature moves, which could be very different from the regular ninjutsu he's used to.
Naruto's fighting style would likely become more refined. With Sakumo's training, he might start using more precise jutsu instead of his usual brute - force attacks. He could also incorporate more strategic movements, like better use of the terrain and stealth.
One possible scenario could be that Naruto, with his powerful jutsu and quick thinking, arrives in the world of Rias just in time to save her from a powerful enemy. Maybe it's a demon or a dark magic user. His speed and strength would be a great asset in this situation.
In this fanfic, Naruto might save Hiashi in a battle situation. Maybe Hiashi is facing a powerful enemy that he can't handle alone, and Naruto steps in with his strong ninja skills. For example, if Hiashi is being attacked by a group of rogue ninjas, Naruto could use his Rasengan to fend them off.
