One possibility is that Naruto enters an AU where chakra doesn't exist. Instead, there are other forms of power. He would have to learn how to use this new power from scratch. Also, the relationships between different ninja clans could be very different. Naruto might end up making new alliances and enemies based on this new dynamic. This could be a great opportunity for character development as he faces challenges that are completely different from what he's used to in his original world.
He could meet an AU version of Hinata who is more assertive and outgoing. Maybe she's a powerful ninja in her own right and not as shy as in the original story.
Well, in a fanfiction where Naruto travels to the past, he could meet his parents when they were young. He could also learn new jutsu from the past ninjas that were lost over time. Maybe he'd even be able to influence the early development of the Hidden Leaf Village in ways that would make it stronger in his own time.
Well, one possibility is that the 'new' Naruto, who is actually the original Naruto in a different role, could change the course of events in the Hidden Leaf Village. Maybe he would approach missions and training in a completely new way, leading to different power-ups and relationships with his comrades.
Well, one possibility is that Naruto might be really confused at first. He'd see this different version of himself as a female and might not immediately understand the situation. He could try to figure out how this time - travel happened and what it means for his world. Maybe he'd start to learn about the differences in how female Naruto is treated in this new world compared to his own experience as a male.
The plot could involve Emil and Richter exploring different magical or historical places. Maybe they are on a quest to find a lost relic that has the power to save their world. Along the way, they could encounter various mythical creatures and face challenges that test their friendship and skills.
One possibility is that Naruto and Naruko are on a mission to save the multiverse in this fanfiction. They travel through dimensions to collect some special artifacts or powers that are scattered across different realities. Along the way, they might face challenges from the rulers of those dimensions who don't want them to take those things. This could involve epic battles and the forging of new alliances as they strive to complete their mission.
In this fanfiction scenario, Naruto could bring his ninja skills to the Def universe. He'd probably have to adapt to the new environment. For example, if the Def universe has different laws of physics, his usual jutsu might not work the same way. He might also learn new techniques from the Def universe and combine them with his own.
One possibility is that their kids would have a very special relationship with the other ninja families in the village. Since Naruto is so well - known and Shikamaru is highly respected for his smarts, the kids might be expected to live up to great expectations. They could also be the center of some new friendships and rivalries among the younger generation of ninjas. And perhaps they'd be involved in some new adventures that are related to the peace - building efforts in the village, just like their parents were in different ways.
Well, in this fanfiction, they could be on a quest for a special artifact in Au. Along the way, they would have to overcome various obstacles like dangerous terrains and traps. They might also meet some friendly locals who could help them in their journey.
They could encounter wise old sages. These sages might offer them advice on their journey or give them clues about their destination. Another type of character they could meet is the bandit. Bandits would try to rob them, forcing Emil and Richter to either fight or use their wits to escape.
