One possible plot twist is that Naruto's death was part of a prophecy all along. His 'death' is the first step in a larger plan to save the ninja world. It could also be that a long - lost relative of Naruto's appears, claiming that they can bring him back to life but at a great cost. This relative could be either a help or a hindrance. Another twist might be that Naruto's death causes a rift between different ninja clans, and it's up to the remaining characters to figure out that Naruto is alive and stop the clans from fighting.
Maybe Naruto isn't actually dead. He could be in a hidden dimension or under some powerful genjutsu that makes others think he's dead.

Or perhaps Naruto's 'death' triggers a hidden power within him that resurrects him in a new and more powerful form.
A plot twist could be that Naruto was abducted by a group of unknown ninjas who made it seem like he was dead. They are using him for some dark purpose, like trying to extract the power of the nine - tailed fox. As the story progresses, his friends start to suspect something is wrong and begin to search for him. Also, it could be that Naruto's death is a test set by the Sage of Six Paths to see if the ninja world can survive without him. If they pass the test, Naruto will be returned, but if not, there will be more dire consequences for the world of ninjas.
Well, one possible plot twist could be that Naruto's coffee - drinking habit reveals a hidden power within him. Maybe the caffeine in the coffee interacts with his chakra in an unexpected way, causing his jutsu to become super - charged.
In some fanfics, the plot twist could involve Harry's so - called death being a misinterpretation. He might have been using a very advanced form of magic that made his life - force seem extinguished. He then uses this false perception to his advantage. He might be able to spy on the Death Eaters or other dark forces without them suspecting. He could also be training in secret during this time to become even more powerful and finally emerge to defeat the real threats to the wizarding world.
Another plot twist could be that Obito is secretly training Naruto to fight against an even greater enemy that no one else is aware of yet. This enemy could be an ancient force that is about to awaken, and Obito believes Naruto is the only one who can stop it. So, he's training Naruto in unique and unorthodox ways that seem strange to others at first.
One possible plot twist could be that Naruto discovers one of the villagers was being controlled by a hidden enemy. This enemy could be using the villager's fear and hatred of Naruto to try and get rid of him.

Maybe the seventh swordsman has a secret power that is unleashed when Naruto is in a dire situation. This power could be something that was thought to be lost or forgotten in the Naruto world, and its appearance changes the entire dynamic of the story.

One possible plot twist could be that Naruto discovers Godzilla is being controlled by an evil force. So instead of just fighting Godzilla, he has to find a way to break the control.

A plot twist could be that Naruto discovers a long - lost connection between the Nine - Tails and some ancient power in Kumo. This could change the whole dynamic of his capture situation. Instead of being a victim, he might become an important figure in Kumo's internal power struggle. And this new - found connection could also lead to a new alliance between Konoha and Kumo in the end. Another twist could be that Naruto's capture was a ruse by Konoha's higher - ups to gain some secret knowledge in Kumo. Naruto was sent there on purpose, but things start to go wrong when Kumo figures out the plan.
One possible plot twist could be that Naruto's closest friend turns out to be secretly working for the enemy.
