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.
Another plot device could be a mind - link or a shared vision. Maybe Naruto has a moment where he links minds with a past Hokage who was an expert in Rasengan. Through this connection, he gains instant knowledge on how to form and use it. It's a more supernatural way of learning compared to the traditional training.
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.
I'm not entirely sure specifically as 'annabeth' is often from the Percy Jackson series and 'rasengan' is from Naruto. It could be a fan - created story that combines elements of both universes in some way, perhaps with Annabeth somehow getting involved with the power or concept of the 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.
Boruto can learn to trust his instincts. Just as Naruto has always relied on his gut feelings, he can teach Boruto that sometimes, listening to that inner voice can relieve the confusion and self - doubt. For example, when Boruto is unsure about a decision regarding his ninja training, Naruto can tell him to trust what he feels is right deep down.
No, Boruto is alive in the manga. The plot hasn't led to his death. However, the manga is ongoing, and anything could happen in the later developments.
Common themes in 'Annabeth Rasengan fanfic' often revolve around identity. Annabeth is a demigod with her own identity, and when she gets involved with the Rasengan, it can create a conflict or an evolution of her identity. Also, there might be a theme of discovery. She discovers the power of the Rasengan and how it can change her approach to fighting and problem - solving. Friendship and teamwork can also be themes, especially if other characters are involved in the story and they have to work together with Annabeth and her new - found Rasengan ability.
