In this fanfiction, the plot could be that Naruto's kid is kidnapped by an old enemy of Naruto's who wants to train the kid to be against the village. The kid has to use his wits and the little ninja training he has received so far to escape. Meanwhile, Naruto is on a desperate search for his child. This would create a lot of tension and also show how much Naruto has grown as a father compared to his own orphaned past.
One unique plotline is when Naruto as a little kid discovers a hidden jutsu that no one else in the village knows about. He has to keep it a secret while also trying to figure out how to master it on his own, which is really exciting.
Another plotline might be exploring Naruto's past more deeply. Maybe there are secrets about his parents that were never fully revealed in the original. In the fanfiction, he could discover something new about his father's time as Hokage or his mother's Uzumaki heritage that changes his perspective on his own powers and responsibilities.
One possible plotline could be Naruto and Hinata using their newfound god - like powers to protect the Hidden Leaf from a powerful, otherworldly threat. They could travel to different dimensions to gather allies or resources. Another could be them having to deal with the moral implications of being gods, like how much they should interfere in the lives of mortals.
A possible plotline is Naruto using his unorthodox methods to solve ANBU - related problems. His creativity and ability to think outside the box could lead to new strategies for the ANBU. He might come up with a new way to gather intelligence or take on a powerful enemy that the traditional ANBU methods couldn't handle.
One interesting plotline could be Naruto using his unique experiences as a former student to develop new and unorthodox teaching methods. For example, he might incorporate his own journey of learning difficult jutsus into his lessons, making it more relatable for his students.
One interesting plotline could be Kaguya's return and her attempt to make amends for her past actions. Naruto, being the protagonist, could be the one to help her in this journey of redemption. This would show a different side of both characters and how they grow together in this new situation.
Another plotline could be Tsunade's role in rebuilding the village after a major battle. It could show her leadership skills, her decision - making process, and how she works with other characters to bring the village back to its former glory. This would involve aspects like rebuilding infrastructure, training new ninjas, and restoring the village's economy.
Perhaps Naruto discovers a new medical jutsu that combines his chakra control with traditional medical knowledge. This could revolutionize the medical field in the Naruto universe. He might use it to heal previously incurable diseases or injuries, and in the process, gain the respect of the medical community. This could also lead to some interesting interactions with other medical ninja, like Shizune or Tsunade.
One interesting plotline could be Naruto dealing with the complex political landscape of the Hidden Leaf as an adult. He might have to make tough decisions regarding alliances and the future of the village.
