One idea could be that Naruto discovers a secret jutsu that has been lost for a thousand years which gives him the power to reverse death briefly. This could lead to him bringing back some important characters from the past for a short time to gain crucial knowledge.
One idea could be that Lady Death appears in the Naruto universe during a major battle. Maybe she's there to claim the souls of the fallen, but Naruto, with his unwavering belief in life and his friends, tries to convince her to spare them. This could lead to an interesting dynamic where Naruto has to prove the value of life to a being who has seen so much death.
One idea could be that the death goddess has the power to bring back characters from the dead in the Naruto universe, but at a great cost. Maybe she offers Naruto this chance to revive his parents, but in return, he has to sacrifice some of his own chakra forever.
In naruto death battle fanfiction, a great plot idea could be a battle royale - style death battle involving Naruto and all of his major opponents throughout the series. Picture Naruto in the middle of a large arena, surrounded by Orochimaru, Pain, Madara, and others, all with their own motives and powers. It would be a chaotic and action - packed fight. Another idea could be a death battle where Naruto has lost his powers and has to rely solely on his ninja skills and strategic thinking. This would show a different side of him. Additionally, a plot where Naruto's death battle is against a powerful, mythical creature from the Naruto universe's lore would be very interesting.
One idea could be Naruto being sent to the world of Death Note. He could use his ninja skills to try and outwit Light Yagami. Maybe he would initially be confused by the Death Note's power but then use his determination to stop Light from his killing spree. Another plot could involve Naruto meeting the Shinigami. He might learn about the balance between life and death in this new context and try to find a way to bring some of his ninja world's values to this strange new world.
Well, a plot could involve Naruto faking his death as part of a training exercise that was actually set up by the older generation of ninja. They want to see how the new generation will react and grow without Naruto's presence. So Naruto goes along with it, but things get complicated when some of his friends start to suspect it's not real and go on a quest to find out the truth. Also, he could fake his death to test Hinata's loyalty or something like that, but that's a bit more of a soap - opera - like plot.
One plot idea could be Lady Death becoming an ally to Naruto during a particularly dark and dangerous mission. Maybe she has some unique powers that can help him defeat a powerful enemy. Another could be a story where Lady Death is sent to the Naruto universe to collect a soul, but she ends up getting involved in the complex politics of the ninja world. A third idea is that Lady Death takes on a human form in the Naruto world and becomes a ninja herself, with her own set of moral and ethical dilemmas as she tries to fit in while still having her otherworldly nature.
One plot idea could be that Naruto loses an eye in a fierce battle against a new, powerful enemy. He then has to adapt his fighting style, perhaps learning new jutsus that rely more on his other senses. Another idea is that he discovers a hidden power within his one eye, like a unique form of the Sharingan that was dormant until the loss of his other eye. Or maybe he gets an artificial eye with special abilities given to him by a mysterious ally.
Well, a great plot idea could be centered around a thousand - year - old prophecy that is just now coming to fruition. The characters in the fanfiction could be on a quest to either fulfill or prevent this prophecy. Or perhaps it could be about a secret society that has been operating for a thousand years and how it affects the current state of the wizarding world in the Harry Potter universe.
One idea could be that the character with the Mystic Eyes of Death Perception is an outsider in the Naruto world. They can see the 'lines of death' on the powerful bijuu, which causes a stir among the ninja villages as they fear this new power. Another plot could involve using these eyes to find a hidden curse in the chakra system that is slowly killing a well - known ninja, and the journey to find a cure.
One plot idea could be a character who was born with only one Sharingan eye and has to struggle to master its powers in a world where most Uchiha have two. They might face discrimination from their clan for being different. Another idea is that a character loses one of their eyes in a battle and then has to adapt to having just one Sharingan, with different abilities emerging as a result of this change. For example, the single Sharingan could have enhanced perception abilities to make up for the lack of a second eye.
