Maybe Sasuke teaches him the Chidori in a moment of camaraderie. And for the Rasengan, it could be an older and wiser Naruto from the future who travels back in time to teach his younger self.
The life expectancy of the Ashura race was 7000 years, which was equivalent to 700 years in the human world. The Asura King Huashan was one of the four great Asura Kings, and he commanded millions of Asura. The karma of the Ashura tribe was determined by their actions and karma in their past lives. There was no relevant information regarding the Karmic Retribution of the Ashura Race.
In many fanfictions, Naruto might master the Rasengan through intense and unique training methods. Maybe he gets some special guidance from an unexpected source, like a hidden shinobi in the village who has a different perspective on chakra control. This person could show Naruto some new ways to focus his chakra, which finally enables him to form the Rasengan successfully.
In some fanfictions, Kakashi could also play a role. He is very knowledgeable and has seen the Rasengan in action. He might offer some tips on chakra control, which is crucial for Naruto to master the Rasengan.
Well, Tsunade could be a great helper. She has extensive knowledge of chakra control and medical ninjutsu. She could teach Naruto how to use his chakra more precisely when creating the Rasengan, perhaps by showing him some medical - ninjutsu - based chakra control techniques that can be applied. Minato, Naruto's father, could also play a role. He was the one who originally created the Rasengan. He could appear in Naruto's dreams or in some sort of time - travel scenario and show Naruto some hidden aspects of the Rasengan creation that he didn't know before. And then there's Sakura. She's become very strong over time. She could use her strength and knowledge to assist Naruto, maybe by creating some sort of training regimen for him to improve his Rasengan creation skills.
Definitely. In the world of fanfiction, the possibilities are endless. If Naruto has Ashura's memories, it could affect his relationships with other characters. He might have a different understanding of Sasuke, for instance, since Sasuke is related to Indra. This could lead to new ways of them interacting and perhaps a different path towards achieving peace in the ninja world. It could also open up storylines about Naruto exploring the past through Ashura's memories and uncovering long - lost secrets.
The top stories on Ashura might include accounts of processions. In many places, there are large - scale processions during Ashura where people come together to remember certain historical events. Also, there could be stories about the distribution of food and charity work that is often associated with this time. Moreover, there might be stories about the sermons and religious teachings that are given during Ashura to educate the community about its significance.
Well, in some fanfics, Naruto might add elements to the Rasengan through intense training and experimentation. He could study different chakra natures and find ways to combine them with the Rasengan's basic form. For example, he might infuse lightning chakra into it to make it more piercing and fast - like a lightning - enhanced Rasengan.
Sakura. It would be really unexpected as she is mainly known for her medical ninjutsu and physical strength. But if she were to learn the Fire Rasengan, it could show a whole new side of her character. Maybe she'd incorporate her medical knowledge into the technique, like using it in a more precise and less destructive way.
