Who could be a potential Naruto Aizen Successor in fanfiction?

The plot could involve this successor being an outcast at first. Since their powers are so different from the regular chakra - based abilities in Naruto. But as they grow in power, they attract the attention of both villains and heroes. Villains might want to use them, while heroes try to stop them from causing chaos. For example, they could create clones that are indistinguishable from the real people, causing all sorts of mayhem in the villages.

One possible successor could be Haku. In some fanfictions, Haku's skills and his close relationship with Zabuza might lead to him taking on Zabuza's legacy. He has the potential to carry forward Zabuza's unique fighting style and perhaps even his ideals in a new generation within the Naruto universe created by fanfic writers.

It could also be a completely new character introduced into the fanfiction. A foreign ninja who was inspired by some of Danzo's ideas (not the bad ones) and comes to Konoha to take on the role of successor, bringing in new perspectives and ways of doing things.

Hinata could be a great choice. In the original series, she has always had feelings for Naruto. In a fanfiction, they could finally get together more easily. Maybe after the war, Naruto realizes how much Hinata means to him and they start a relationship.

There could be an entirely new character created as a necromancer in Naruto fanfiction. This character could be from a hidden clan that has long been rumored to have necromantic abilities. They could enter the Naruto world and disrupt the balance between life and death, causing all sorts of chaos and new storylines to unfold.

One possibility is that Naruto's reincarnation as Aizen would lead to a whole new set of battles. He might face off against some of the powerful Hollows or even the more powerful Soul Reapers who see him as a threat. His Naruto - based powers could be a huge advantage in combat. He could use his chakra control to enhance his sword skills or his ability to sense spiritual pressure. And his journey through the Bleach world as Aizen could be about finding a way to bring peace, just like he always aimed for in the Naruto world.

Well, in a fanfiction scenario, Naruto might kill Aizen if he manages to use his shadow clones to outwit Aizen's illusions. Naruto could also use his Sage Mode to sense Aizen's reiatsu and counter his attacks. Maybe he combines his Rasengan with some new jutsu he's developed specifically to deal with Aizen's powers.

Another aspect could be that the successor discovers some long - hidden secrets left by Danzo. These secrets could be related to powerful jutsu or ancient ninja lore. And as they uncover these secrets, they have to decide whether to use them for the good of the village or keep them buried to avoid causing chaos.

Perhaps a foreign ninja who comes to the Hidden Leaf Village. They bring with them the scythe - using techniques from their own land. This ninja could be on a mission to learn more about the chakra system in the Naruto world and in exchange, teach their scythe skills. Their different cultural background would add an interesting dynamic to the story as they interact with the local ninjas.

Naruto himself could be a potential character, perhaps in a mentoring role to the 6th Hokage. Sasuke could also be there, maybe as an ally or a rival in some aspects of the story.
