One common theme is redemption. After the war, Sasuke is often seen trying to atone for his past actions in these crossovers. For example, in a crossover with a post - apocalyptic world, he uses his skills to protect the survivors, which is his way of making up for the harm he caused in his own world.
One great post - war Sasuke crossover fanfiction is 'Sasuke in the World of Harry Potter'. It's really interesting to see Sasuke's ninja skills and his complex personality in the magical world. He forms unique relationships with the Hogwarts students and even has some epic battles against dark wizards, all while trying to find his place in this new world.
One way to develop their relationship could be through shared trauma from the war. The OC could have also been involved in the war efforts, and they start to bond over their experiences. They might initially be hesitant, especially Sasuke with his guarded nature. But as they work together to rebuild their world post - war, they gradually open up to each other.
One common theme is adaptation. Naruto and other characters have to adapt to the new world they are in during the crossover. For example, if it's a crossover with a modern - day world, they have to understand new technology and social norms.
Survival is a big theme too. In a post - war situation, Ichigo has to survive in a world that he's not familiar with. In a crossover with the Hunger Games world, he has to use his skills to stay alive in the deadly arena, all while trying to find a way to get back to his own world.
Another great one is 'Ichigo and the Avengers Post - War Crossover'. This fic brings Ichigo into the Marvel universe after his own war. He teams up with the Avengers and they all learn from each other. Ichigo's swordsmanship and spiritual powers are quite different from the superpowers of the Avengers, so there are a lot of cool fight scenes and interactions between the characters.
They could embark on a journey to restore the balance of chakra in the world. Since the war might have disrupted the natural flow of chakra, the OC, with their unique skills perhaps in chakra sensing or manipulation, and Sasuke with his powerful abilities, could team up. They would face various challenges like dark chakra entities that emerged due to the war's chaos.
One popular post - war Naruto crossover fanfiction is 'Naruto and the Avengers: A New Alliance'. It combines the post - war Naruto universe with the Avengers. In this fic, Naruto and his friends team up with the Avengers to face a new threat that endangers both their worlds. It's full of exciting battles and interesting character interactions.

One great 'Naruto Sasuke Crossover Fanfiction' is 'The Bond Beyond Worlds'. It delves into an alternate universe where Naruto and Sasuke are transported to a different realm.
