In a fanfiction where Naruto's mother is alive, she could play a crucial role in Naruto's relationships. For example, she might have been able to prevent some of the villagers' hostility towards Naruto. Since she was from the Uzumaki clan, which was highly respected for its sealing abilities, her presence could have made the villagers think twice about mistreating her son. Also, Naruto would have had a family figure to rely on, which would have changed his character development significantly.
If Naruto's mother was alive in fanfiction, one major change could be in Naruto's upbringing. He might not have been as lonely as in the original story. His mother could have taught him about his Uzumaki heritage and the special powers that come with it, like strong life force and powerful sealing jutsu. This could have made Naruto a more confident and well - rounded shinobi from the start.
The story would be very different. Naruto's parents being alive would mean he has a support system from the start. His father could pass on his jutsu and wisdom more directly. Naruto might not have the same drive to become Hokage in the same way, as he wouldn't be seeking that family - like recognition from the village. His mother's presence would also add an element of warmth and stability to his life. And perhaps he would be more of a prodigy with both his parents' guidance, changing the power dynamics in the ninja world.
If Kushina were alive in Naruto fanfiction, it could change the story in many ways. For one, Naruto would grow up with a mother figure. He might not have faced so much loneliness and discrimination in the village as Kushina could have protected him. Also, Kushina was a powerful kunoichi. She could have trained Naruto herself, perhaps passing on unique Uzumaki techniques earlier. This could have made Naruto even stronger, more quickly.
If Kushina was alive in a fanfiction, Naruto's relationship with his father, Minato, would be different. They could all be a proper family, and Naruto would grow up with both his parents. His relationship with his friends might also change as he would have a more stable home life. For example, he might be more confident around Sakura and Sasuke, and his bond with them could be less about seeking acceptance due to his lack of family.
The plot would change a great deal. For example, Naruto might not have that initial drive to become Hokage just to be recognized. His goals could be more centered around family and protecting the village in the name of his mother. Also, his relationships with other characters like Sasuke would be different. He might not be as competitive with Sasuke since he'd have a more stable upbringing.
His friends might be initially shocked. But Naruto being Naruto, they would soon accept it. Sasuke might see Naruto's alien heritage as a new way to gain power and become more interested in working with him again. Sakura would be worried about the potential dangers it could bring to Naruto, and be more protective. Shikamaru might find it all too troublesome at first, but then start to strategize on how to use Naruto's newfound abilities for the village's benefit.
The 'Naruto Kyuubi Mother' concept can change Naruto's story by adding a new source of guidance. Instead of just relying on Jiraiya or Kakashi, he now has this mysterious connection to the Kyuubi's mother which can lead him in different directions.
The story could have some interesting twists. Maybe Naruto starts spending more time reading fanfiction instead of training, which would surely annoy his mentors. His friends might be confused at first about his newfound love for these fictionalized versions of their lives.
With Sasuke, Naruto's parents being alive could lead to a more positive influence on Sasuke. Naruto might be more stable and happy, and this could rub off on Sasuke. They could become closer friends earlier, and Naruto could help Sasuke deal with his family issues in a different way. Maybe Naruto's family could even offer some support to Sasuke after the Uchiha massacre didn't happen.
Well, if Tsunade were Naruto's mother in fanfiction, it would likely change the story a great deal. For one, Naruto might have had a more stable upbringing in the village. Tsunade could have protected him from some of the early hardships he faced, like being ostracized for having the Nine - Tails. Also, Naruto might have learned medical ninjutsu much earlier from Tsunade, which could have added a new dimension to his fighting style. And perhaps he would have had a more confident personality from the start, since Tsunade is a strong - willed and confident character herself.
A fanfiction storyline could be that Naruto's mother is alive and she reveals to Naruto secrets about his father, Minato, that no one else knew. This could lead to Naruto having a different perspective on his father and his own role in the village. Also, Kushina could be part of a secret organization within the village that is dedicated to protecting ancient shinobi secrets, and she brings Naruto into this world of mystery.
