In fanfiction, when Naruto is reanimated by Edo Tensei, his character can change in multiple ways. His memories might be clouded, making him less empathetic. He could be more of a puppet following the commands of the reanimator. Also, his sense of justice might be warped. For instance, if the reanimator wants to target the Leaf Village, Naruto might not be able to oppose it as strongly as he would when alive due to the control of the Edo Tensei. His carefree attitude could be replaced with a more solemn and menacing demeanor.
He might become more aggressive. The process of Edo Tensei could taint his positive nature. Instead of his usual friendly self, he could be more focused on the task given by the caster of the jutsu, which may be to cause destruction.
If Naruto is reanimated by Edo Tensei in fanfiction, it could lead to a very different story arc. Naruto's abilities like his Rasengan and Sage Mode could be enhanced or distorted in this reanimated state. The story could explore how the village he loves so much reacts to his reanimation. His relationships with other characters would also change drastically. For example, Sasuke might be conflicted about fighting a reanimated Naruto. Also, the one who performs the Edo Tensei would have a difficult time controlling Naruto if his willpower remains as strong as it was when he was alive.
In certain fanfic concepts, Naruto could learn Edo Tensei from Kabuto. Kabuto, having mastered the jutsu, might decide to teach Naruto for some reason. It could be because he sees Naruto's potential to use it in a more positive way compared to how he misused it. Naruto, with his strong sense of justice, would then try to modify the jutsu to be less evil - like not using it to bring back people against their will.
They could change the storyline by providing Naruto with a stronger support system. Since they are his clan members, they might have knowledge and skills that can help him in his battles and his journey to become Hokage. For instance, they could teach him some powerful Uzumaki sealing techniques that no one else in the village knows.
If Naruto was revived by Edo Tensei in fanfiction, the story's dynamics would shift significantly. For one, his revived self could bring back forgotten techniques or knowledge. This could help in battles against stronger opponents. Also, his return would likely cause emotional turmoil among his friends. Some might be overjoyed, while others could be conflicted about his undead state. And his actions could set off a chain of events that would rewrite the entire plot of the fanfiction.
In a Fairy Tail fanfiction involving Naruto's Edo Tensei, it could work by a mage in the Fairy Tail world somehow getting access to the same jutsu principles. Maybe they discover ancient scrolls that detail similar resurrection magic. The Edo Tensei in Naruto brings back the dead with a sacrifice and control over the resurrected. In the Fairy Tail fanfic, it might be tweaked to fit the magic system there, like using magical energy instead of chakra for the sacrifice and control part.
In fanfiction, the Edo Tensei release can create a whole new set of alliances and rivalries. When characters are released, they might not be as beholden to the original caster's wishes. For example, if the Sound Four were released, they could form an alliance with some of the Konoha ninjas against a common enemy. This would add new layers of complexity to the story. Also, the release can lead to a change in the power balance. If a powerful Edo Tensei - controlled character like Kisame is released, he could either become a great asset or a huge threat depending on his motives.
Well, Naruto's Edo Tensei can add an element of the undead and powerful combatants to Teen Titans fanfiction. The Edo Tensei ninjas can bring in their unique jutsu and fighting styles. For instance, the ability to use shadow clones or fire - style jutsu in the Teen Titans' city would be a really cool addition. It could also create a new dynamic where the Titans have to deal with these powerful, resurrected foes or allies.
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.
He would be surprised. Naruto is always ready for a fight, but seeing the Edo Tensei army would still catch him off guard. Then he'd be determined to protect his village and friends from this new threat.
Her character could also grow in the fanfiction by interacting with other characters from Naruto's generation. She might be surprised at how far the ninja world has come and could offer her unique perspective on things, which in turn shapes her character further.
