The plot could involve a common enemy that both Naruto and Beelzebub have to face. For example, a powerful demon that threatens both the ninja world and the world of Beelzebub. Naruto's determination and Beelzebub's unique abilities would combine to take on this threat. They might start off as rivals, not trusting each other at first, but as they face challenges together, they form an alliance. Naruto could show Beelzebub the value of friendship and loyalty, which are important themes in his own world.
Imagine if there was a tournament that brought the best fighters from both universes together. Naruto, Sasuke, and the others from the Naruto world, and Kai, Jay, and the rest from Ninjago. They start off competing against each other but then realize there is a greater threat lurking. A group of shadowy figures wants to steal the powers of both ninjas and warriors. So, they must put aside their differences and combine their skills to fight this new enemy.
The plot could involve a threat that requires the combined efforts of both universes. Maybe an ancient evil that can only be defeated by the unique powers of Naruto characters and the technology and superpowers of Marvel heroes. For instance, a villain who can absorb all forms of energy is threatening both the ninja world and the Marvel universe. Naruto and his friends team up with the Avengers to stop this threat. Along the way, they have to learn to work together, which could lead to some interesting character interactions, like Naruto trying to understand Stark's high - tech gadgets or Thor explaining his Asgardian magic to the ninja.
The plot could involve Naruto characters in a Disney - like world. For example, Naruto might find himself in the world of 'Frozen' and team up with Elsa to stop an evil jutsu - using snow monster. He could use his Rasengan against the icy threats while Elsa uses her ice powers to assist him. This would be a cool mix of the ninja - like action from Naruto and the magical, fairy - tale setting of Disney.
One possible plot could be that Naruto is somehow transported to the world of Beelzebub. There, he meets Oga Tatsumi and they initially have a misunderstanding and fight. But then they realize they have common goals, like protecting their respective friends and families. Naruto could use his ninja skills, like shadow clones, to help Oga in his battles against other delinquents or supernatural threats in the Beelzebub world.
Well, it could be really interesting. Maybe Naruto and his friends somehow end up in the world of Dog Days. Naruto might be confused by the different rules and the animal - like characters. He could use his ninja skills in unique ways there. For example, his shadow clone jutsu could be used to create distractions during battles in Dog Days' world. And his determination to protect his new friends in this strange land could drive the story forward.
Their interaction could also be full of challenges. Since they come from different worlds with different power systems, they might accidentally clash. For instance, Naruto's use of chakra could be misinterpreted by Beelzebub's side as some kind of threat. But once they communicate better, they could find ways to use their combined powers. Naruto could use his shadow clone jutsu to create distractions while Beelzebub attacks with his full force. They would gradually learn to work together and even become friends, with Naruto's friendly nature breaking down any initial barriers between them.
The plot could involve Naruto characters in the Assassin's Creed world. Maybe Naruto himself could be an assassin with his ninja skills. He'd be sneaking around ancient cities, using his shadow clones to distract guards just like assassins use decoys. It would be really cool to see him climb buildings and assassinate targets in a more historical and different setting than the ninja villages.
A Gintama and Naruto crossover fanfiction could be really interesting. It might start with Naruto characters somehow ending up in the Gintama world. Maybe Naruto and his friends are on a strange mission and get sucked through a portal into Edo. They would be shocked by the wacky and modern - yet still somewhat feudal - nature of the Gintama world. Gintoki could mistake them for some new weirdoes in town. And then there could be all kinds of chaos as Naruto tries to use his jutsu, which might have unexpected effects in the Gintama universe due to its different rules of physics and such.
In this crossover fanfiction, the art styles could also blend in an interesting way. The distinct anime - like look of Naruto characters against the more urban and gritty style of the Boondocks. Story - wise, perhaps there's a common enemy that both Naruto and the Boondocks characters have to face together. It could be someone who wants to disrupt both the ninja world and the Boondocks' community, forcing them to team up and use their combined skills and knowledge to defeat it.
It could be really exciting. Maybe Naruto and his friends find themselves in the Pokemon world. Naruto might try to catch Pokemon using his ninja skills. He could use his shadow clone jutsu to surround a wild Pokemon and then throw a Pokeball. And the Pokemon in this crossover could learn some ninja - like moves. For example, Pikachu could learn how to move as fast as Naruto does.
