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.
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.
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.
Mostly, yes. Fanfiction writers love to play with the idea of Naruto's Rasengan. They might give it new forms, like a lightning - infused Rasengan or a Rasengan that can split into multiple smaller ones. Since the Rasengan is so central to Naruto's character in the original story, it often makes an appearance in fanfiction, but of course, there are always exceptions depending on the unique ideas of each writer.
I really liked 'Naruto's Rasengan Adventure'. In this fanfiction, Naruto has a really hard time with the Rasengan at first. But his unwavering spirit keeps him going. It shows his training in a very detailed way, like how he messes up over and over but still doesn't give up. It's inspiring.
One great fanfiction about Naruto learning Rasengan might focus on his intense training sessions. It could show his struggle to master the chakra control required. He might start with basic exercises, like spinning a small ball of chakra in his palm, and gradually build up to the full Rasengan. This type of fanfiction often adds more emotional depth to Naruto's journey, showing his determination and the pressure he feels to succeed.
In some fanfictions, Naruto might learn Rasengan through the guidance of an alternative mentor. Maybe a powerful shinobi from another village takes him under their wing and shows him different techniques to master the Rasengan. This could add a whole new dynamic to the story and his character development.
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.
One possible new form could be an earth - enhanced Rasengan. It might be heavier and more solid, able to break through tough defenses like rock walls. Another could be a wind - enhanced Rasengan that has even more cutting power than the regular one. Maybe it can slice through thick metal with ease.
The key element is Naruto's determination. In any 'naruto creates the rasengan fanfic', his unwavering will to master the Rasengan is central. It drives the plot forward.
