One possible interesting plot could be Madara, in his Edo Tensei form, somehow regaining his full power and challenging Naruto not in a fight to the death but in a battle of wits. Naruto, on the other hand, tries to find a way to either seal Madara permanently or make him see the error of his ways. For example, Naruto could use his talk - no - jutsu to try and convince Madara that his quest for power has only led to destruction.
A plot where the Edo Tensei of Madara has some unforeseen side effects. Instead of being the powerful and ruthless fighter he was, he has moments of his former self, the one before he was consumed by hatred. Naruto, sensing this, tries to bring out more of that old Madara. He shows Madara the new ninja world that has been created, with peace treaties and cooperation among the villages. This makes Madara question his past actions and his view of the ninja world.
Perhaps a plot where Naruto and Edo Tensei Madara have to team up against a greater threat. This new enemy could be a powerful being from another dimension that has the power to destroy the ninja world. Madara, despite his initial reluctance, realizes that he needs to work with Naruto to save the world he once wanted to rule. They combine their unique skills, like Naruto's Rasengan and Madara's Susanoo, to fight this new foe.
Many fanfictions also touch on the theme of the afterlife. Since Edo Tensei is a form of resurrection, questions about what it means for Madara to be brought back, and how it relates to the afterlife in the Naruto universe are often explored. There could be stories that delve into his relationship with the person who resurrected him and what their end goals are in relation to his Edo Tensei state.
Naruto might initially be on guard and hostile towards Edo Tensei Madara. But as Naruto is, he would also try to understand Madara's motives. He could start by trying to talk to Madara, asking him why he still clings to his old ways even in his undead state.
There's also a possibility that it could be an unknown villain. A new character created by the fanfiction author who has a vendetta against Konoha or the ninja world in general and believes that resurrecting Naruto through Edo Tensei would be a way to start some sort of revolution or destruction.
One possible plot could be that through the Edo Tensei jutsu, Mito Uzumaki is brought back to life. She teams up with Naruto. They could face off against an ancient enemy that once threatened the Uzumaki clan. Mito shares her old - world knowledge and skills with Naruto, and together they strive to protect the Hidden Leaf Village from this new threat.
Well, one possibility could be that Naruto is brought back by Edo Tensei to face a new, even greater threat that only he can handle. Maybe the Hidden Villages are being attacked by an ancient evil that they have no knowledge of how to defeat. Naruto's return gives hope to the shinobi world and he uses his unique skills and charisma to rally everyone together.
The plot might also involve a situation where the Edo Tensei Hokages have to interact with their past selves in some way. Maybe a time - warp or some sort of magic makes it possible. They could then pass on wisdom or correct past mistakes.
A great plot in 'naruto edo tensei fanfiction' might be an alternate universe where the edo tensei is not a jutsu used for combat but for a more peaceful purpose like resurrecting historical shinobi to teach the new generation. This could lead to all kinds of cultural exchanges and unique training sessions for characters like Naruto and his friends. Also, a plot where edo tensei characters rebel against their summoners due to having their own wills and agendas would be exciting.
One great Naruto Edo Tensei Madara fanfic is 'The Resurrected Conquest'. It really delves into what Madara could have done if he had more time during his Edo Tensei state. The story has some amazing fight scenes and really captures Madara's character well.
The popularity of Naruto Edo Tensei Madara fanfic lies in the character of Madara himself. He's such a complex and powerful character in the Naruto universe. When brought back by Edo Tensei, it adds another layer of intrigue. Writers can explore different scenarios with him, like how he would interact with the modern - day ninja world.
One idea could be the clones having unique abilities different from the original edo tensei summons. For example, they might be able to combine jutsus in unexpected ways.
