One possible plotline could be that Naruto inherits Sakumo's calm and strategic mindset. Since Sakumo was known for his intelligence in battle, Naruto might grow up to be a more cerebral ninja. He could also learn Sakumo's unique jutsu and techniques, which would set him apart from his canon self. Another aspect could be how Naruto's presence affects Sakumo's fate. Maybe Naruto's positive attitude and will to change things could prevent Sakumo from succumbing to the despair that led to his downfall in the original story.
Naruto's combat style would be more refined. Sakumo was a highly skilled ninja, and he would teach Naruto better swordsmanship skills perhaps. Naruto's taijutsu could also be more precise and calculated. Also, Naruto might develop better chakra control earlier, as Sakumo could instill in him the importance of efficient chakra usage from a young age.
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.
Maybe Naruto saves Sakumo by bringing back his honor. He could prove to the village that Sakumo's actions were actually for the greater good. Naruto, being a hero in the village, has the influence to change people's perception. So he might start a campaign to rehabilitate Sakumo's name, which in turn could save Sakumo from his despair.
Sakumo's presence could make Naruto more confident in his own abilities. Since Sakumo was a great ninja, his guidance could give Naruto new perspectives on his training. Naruto might also become more strategic in his battles, learning from Sakumo's combat experience.
Well, it's hard to name just a few as there are so many talented writers out there. But some authors who have a good reputation for writing in this area might be those who really understand the Naruto universe and the character of Sakumo Hatake. They are the ones who can write about his relationship with other characters in a believable way.
It could be a rogue ninja who is after Sakumo's hidden techniques. Since Naruto meets Sakumo, this rogue ninja sees Naruto as an obstacle and tries to eliminate him. This antagonist might have a grudge against the Hatake clan and wants to use Sakumo's secrets for his own evil purposes.
One interesting fanfiction could be about Sakumo Hatake's early days as a ninja, his training methods, and how they might have influenced Naruto later. For example, a story could explore how Sakumo's values of loyalty and self - sacrifice were passed down in the village and how Naruto might have learned from his legacy.
One possible plot could be that Naruto accidentally time - travels and meets Sakumo Hatake. Sakumo, being an experienced ninja, could start training Naruto, sharing his unique jutsu and combat wisdom. This encounter might change Naruto's understanding of ninja values and help him grow even stronger in his own time.
In a fanfiction where Naruto is trained by Sakumo Hatake, Naruto might learn some unique jutsu. Sakumo was known for his skills, so Naruto could inherit some of his sword - based techniques. Maybe Naruto would develop a new style of combat that combines his own Uzumaki chakra powers with Sakumo's teachings.
