Naruto himself is likely to be very popular. His reanimated version could have all sorts of new storylines. Sasuke is also a popular character that would be interesting to see reanimated. His complex personality and powerful abilities would make for great fanfic material.
It could be Orochimaru. He has always been interested in the power of the dead and bringing back the strong. He might have found a way to reanimate Naruto for his own evil purposes, like using Naruto's power to take over the ninja world.
One interesting plotline could be Naruto coming back reanimated and having to face new enemies that his old friends can't handle alone. His reanimated state might give him unique powers or abilities that change the course of battles.
One common theme is the exploration of family bonds. Naruto has always longed for a family, and when he reanimates them, it delves deep into how those relationships can be rebuilt and strengthened. Another theme is the idea of second chances. His family gets a chance to be part of Naruto's life again, and Naruto gets a chance to experience a family upbringing he missed. It also often includes themes of sacrifice, as Naruto may have to sacrifice something in order to reanimate his family, whether it's his own energy or something else.
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.
Well, I'm not sure of the exact title, but there are some fanfictions where Naruto reanimates his family in order to gain closure. He might be haunted by the loss of his parents especially. So, he uses his skills and some unexpected help to bring them back. It then becomes a story of redemption and love as he tries to make up for the time they lost and protect them from the threats that still exist in the ninja world.
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.
One interesting plot idea could be Minato's reaction to seeing how Naruto has grown. He could be both proud and a bit sad for missing out on so much of his son's life. Another idea is that Minato could use his reanimated state to teach Naruto some new jutsu that he didn't have time to pass on before. Maybe he could also interact with the other characters in Konoha and share his insights from his time as Hokage.
