The Edo Tensei Hokages would likely interact with a great deal of respect for each other. They come from different generations but share the common bond of leading the Hidden Leaf. They might exchange stories of their leadership challenges.
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.
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 great Naruto fanfiction with Edo Tensei Jiraiya could be about him coming back during a crucial battle. He could use his vast knowledge and powerful jutsus to turn the tide. For example, he might face off against an old enemy who has now become even more powerful. His return could also have a big impact on Naruto, as he could pass on some final teachings or advice.
Well, in a 'naruto knows edo tensei fanfiction', it could be about Naruto having some special knowledge or encounter related to the Edo Tensei jutsu. Maybe he discovers a new way to counter it or uses it in a unique situation.
Well, I remember a fanfic called 'Kushina in the Edo Tensei World'. It's a bit different. Instead of just focusing on her relationship with Naruto, it delves into how Kushina adjusts to being brought back by Edo Tensei. She has to come to terms with the new world she's in, all while trying to protect Naruto from threats that she discovers are still lurking in the shadows. It's really interesting as it gives a new perspective on the whole Edo Tensei concept in relation to Kushina.
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.
If Naruto is resurrected by Edo Tensei in the fanfiction, he could have a different perspective on life and death. Since he's come back from the dead, he might be more determined to achieve certain goals that he didn't fully accomplish when he was alive. He could also interact with characters who have passed away in a very different way. For instance, he could meet his father again and have some deep conversations about the future of the ninja world. This would add a lot of emotional depth to the story.
A possible fanfiction idea is that Edo Tensei Jiraiya teams up with Naruto and Sasuke. Since Jiraiya knew both of them in different ways, his presence could help resolve the remaining tensions between the two. They could go on a mission to stop a new threat that is using an ancient and powerful jutsu. Jiraiya's experience with different types of jutsus could be crucial in figuring out how to counter this new enemy.
Yes, in fanfiction, the author has the creative freedom to make Naruto use Edo Tensei in the Fairy Tail universe. It's a cool crossover concept that can lead to some interesting storylines.
