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.
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.
One idea could be exploring the backstories of the Edo Tensei - summoned ninjas in more depth. For example, you could focus on the relationships they had before their deaths and how those relationships are affected when they are resurrected. Another idea is to have a character somehow break free from the control of the Edo Tensei jutsu and try to stop the summoner. This could lead to some really intense battles and moral dilemmas.
Itachi is often a very popular character in edo tensei Naruto fanfiction. His complex backstory and his relationship with Sasuke make him a prime candidate for interesting fan - created stories in the edo tensei setting.
In some edo tensei Naruto fanfictions, the rules of the edo tensei jutsu are altered. This could lead to some really creative plotlines. For instance, the resurrected characters might be able to retain their memories more clearly or have different abilities compared to what was shown in the original series. This allows for new and exciting battles and interactions within the Naruto universe.
Definitely Itachi Uchiha. His character is complex and his skills are amazing. Having him in an Edo Tensei fanfic can add a lot of depth and mystery. Another popular choice is Minato Namikaze. Fans love his cool - headedness and his powerful jutsu. His presence in an Edo Tensei - related story can bring in a lot of action and strategic elements.
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.
A lot of these fanfictions explore the concept of power differences. The Edo Tensei ninjas are often very powerful, and when they meet the Teen Titans, there can be a lot of misunderstandings at first. But as the story progresses, they learn to work together. Some fanfictions also focus on how the different moral codes of the two universes interact, like the ninjas' code of loyalty and the Titans' sense of justice.
Perhaps an old enemy from Naruto's past that was thought to be defeated but has somehow returned stronger. Maybe Orochimaru, if he has found a new way to gain power and wants to test himself against Naruto once again. He might be jealous of Naruto's popularity and the fact that he was always seen as a hero, so he uses Edo Tensei to bring Naruto back just to defeat him and prove that he is the stronger one.
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.
