One interesting plot could be Naruto arriving in a universe where the Akatsuki are the heroes. He'd be so confused as he's always seen them as villains. Another could be a universe where ninjas don't exist, but he still has his powers. He'd have to figure out how to hide or use them in a completely different world. Maybe in a third plot, he travels to a universe where all his friends are his enemies, which would be a huge emotional and physical struggle for him.
If Naruto travels to an alternate universe, his relationships would change drastically. For example, if he meets his friends' alternate versions, they might have different personalities. His relationship with Sasuke could be very different. Maybe in this new universe, Sasuke is a laid - back person instead of brooding. His bond with Sakura could also change. If she's a more confident and powerful ninja in the alternate universe, Naruto might see her in a new light.
First, come up with a unique concept for your alternate universe. It could be something like a world where ninjas use modern technology. Then, think about how the characters will be different. For Naruto, maybe he's not an orphan or he has different abilities. Next, plan out the plot. You can start with a small change in the Naruto universe and build on it. For instance, if the Uchiha clan was never massacred, how would that change the relationships and the overall story?
