A more complex plot could be Indra Otsutsuki crossing over into a post - apocalyptic world. He has to use his skills not only to survive but also to protect the remaining survivors from various threats. This could include mutated creatures or other powerful entities. As he tries to find a way back to his own world, he also discovers secrets about this new world that could change everything.
Another plot could involve Indra crossing over into a different anime universe, like the Bleach universe. He might encounter the Soul Reapers and Hollows. His unique powers from the Naruto world would create interesting interactions. For example, his Sharingan could potentially be used to see through some of the illusions in the Bleach world. And he could form alliances or rivalries with the characters there.
One idea could be Indra Otsutsuki crossing over into a modern-day world. He could struggle to adapt to the new technology and social norms while still having his powerful ninja abilities. Maybe he meets a group of people who initially fear him but then come to understand his situation and help him navigate this strange new world.
One idea could be to cross Hagoromo Otsutsuki with a character from a different anime universe, like Goku from Dragon Ball. They could have a power - level comparison and then team up against a common enemy. Another plot could involve Hagoromo in a modern - day world crossover, where he has to adapt to new technology while still using his ancient powers.
One idea could be an otsutsuki crossover with the Naruto universe. Imagine an otsutsuki character interacting with Naruto and his friends, perhaps teaching them some of their unique jutsu or having a power struggle. Another idea is an otsutsuki crossover with a different anime like One Piece. The otsutsuki's otherworldly powers could create chaos in the Grand Line.
Well, a plot could be that Sakura is a healer in a war - torn land and Indra is a powerful warrior. Indra gets seriously injured and Sakura has to use her skills to heal him. During his recovery, they start to have deep conversations about life, power, and the purpose of war. This could lead to a change in Indra's perspective on things and a budding relationship between them. It could also create conflict as some in Indra's clan might not approve of his new - found friendship with Sakura.
One idea could be an Otsutsuki OC who comes to Earth not for conquest but to study the unique life forms here. They could befriend some of the local ninjas and learn about the concept of friendship, which is alien to the Otsutsuki. This would lead to a series of adventures where they have to protect their new friends from other more hostile Otsutsuki members.
One interesting plot could be exploring what would happen if Ashura and Indra were reincarnated in the modern era of the Naruto world. How would they adapt to the new technology and social changes while still having their ancient feud?
Well, perhaps a plot where Asura and Indra are given a chance to rewrite their history. They start to understand each other's viewpoints better and try to create a new future for the ninja world. They could also meet their descendants, like Naruto and Sasuke, in a different dimension and exchange knowledge and power.
Well, a plot could involve Naruto's connection to Indra leading him to unlock ancient jutsu. Since Indra was a powerful figure, Naruto might have to learn to control the immense power within him. He could also be involved in a prophecy related to his father's legacy, which would set him on a path to save the ninja world in a new and unexpected way.
One idea could be a story where a young ninja discovers they have a hidden Otsutsuki bloodline power that gives them the ability to control gravity. This power sets them apart from their peers and makes them a target for both those who want to use their power and those who fear it.
One idea could be a crossover where Naruto's Otsutsuki powers somehow connect with the supernatural elements in DxD. For example, his ability to absorb and use chakra could be related to the magic in DxD. Maybe he could use his Otsutsuki powers to enhance the abilities of the devils or angels he meets in the DxD world.
One idea could be a story where an Otsutsuki member infiltrates the Akatsuki. They could have their own secret motives that conflict with the Akatsuki's goals, like using the Akatsuki as a tool to gather more chakra for their own clan's needs. Another plot could be about a young Naruto being mentored by an Otsutsuki in secret, and how this affects his relationship with the Akatsuki later on. Maybe he tries to persuade them to change their ways using the knowledge he got from the Otsutsuki.
