pain uses chibaku tensei

He could develop a sense of self - doubt. Maybe the process of using Chibaku Tensei makes him question if he's becoming too powerful and if he's still the same Naruto. He might worry that his friends will start to see him differently, as someone who wields such a terrifying ability. This could lead to some internal struggles within his character as he tries to balance his new power with his old self.

It could be a rogue ninja who has mastered the Chibaku Tensei technique and wants to use it to reshape the ninja world according to his own dark vision. He might see the current system as corrupt and decides to use extreme measures to create a new order.

One possible plot could be that Naruto uses Chibaku Tensei to stop an extremely powerful enemy. Maybe he has to make a great sacrifice to master this powerful jutsu first. He might have to isolate himself to train in a special place and learn about the nature of the Chibaku Tensei from ancient scrolls or a hermit. Then, when the enemy arrives, Naruto uses the Chibaku Tensei, creating a huge gravitational pull that traps the enemy. However, this also takes a toll on his body as it's not a jutsu he's used to using.

One idea could be a story where Naruto has to reverse the Chibaku Tensei technique used by an unexpected enemy. Maybe a new villain has found a way to corrupt the original jutsu and Naruto has to figure out how to stop the destruction it's causing.

One common theme is redemption. Naruto often uses rinne tensei to bring back characters who have made mistakes in the past and gives them a chance at redemption. Another theme is sacrifice, as using rinne tensei usually comes at a great cost in these fanfics.

He could revive Minato. Minato was a very powerful ninja, and his return could help Naruto in terms of combat skills and strategic thinking. Also, Minato could pass on some unique jutsus or knowledge that he didn't have a chance to before.

There's a fanfic called 'Naruto's Rinne Tensei Adventure'. Here, Naruto uses rinne tensei to save the village in a time of great peril. The story is full of action and also delves into the moral implications of using such a powerful jutsu. It's a great read if you like Naruto fanfics with a bit of depth.

In the fanfic, Naruto might use Edo Tensei to resurrect Orochimaru in a controlled way. Since Orochimaru has extensive knowledge of jutsus and the ninja world, Naruto could use him to gain insights into some ancient and powerful techniques. This would create an interesting dynamic as Naruto has to keep Orochimaru in check while also using his knowledge for the greater good.

The story could start with Harry discovering the knowledge of Edo Tensei. Maybe he stumbles upon an ancient text during one of his adventures in the restricted section of the Hogwarts library. Then, he might initially be hesitant to use it but as the threat in the wizarding world grows, he decides to give it a try.

There would be chaos. The Edo Tensei brings back the dead, and in Fairy Tail, it would disrupt the natural order. Maybe the revived characters would cause trouble or be used as powerful weapons.
