Naruto is often paired with Madara in some fanfictions. Their interactions can be really intense, as Naruto tries to either convince Madara to change his ways or fight against his reborn form.
One common theme is the clash of cultures. Since it's a crossover, Madara from his original world has to deal with different cultural aspects in the new crossovers. Another theme is power struggle. Madara is often a very powerful character, and when he is reborn into new settings, there's often a struggle for power between him and the existing power structures in those worlds.
Well, it depends on different fanfictions. Some might have Madara being reborn with all his former power and knowledge, leading to epic battles against new foes or old rivals reimagined in new scenarios.
Well, a major theme is the exploration of the past and present. Since Naruto is reborn as Madara, he has access to Madara's memories, so there's a lot of looking back at the history of the ninja world. Also, the theme of friendship is present but in a new light. His old friends now see him as Madara, and he has to figure out how to maintain those relationships. And power dynamics are a theme too, as his new power level changes how others interact with him.
