Well, a possible plot might involve Naruto and Meliodas growing up together in a world that is a mix of the Naruto and Seven Deadly Sins universes. They could face discrimination because of their unique powers and brotherly bond. Or perhaps they are separated at a young age and have to find each other again while uncovering secrets about their family and the two worlds. It could also be that they have to protect their family's legacy which is tied to both the ninja and demon - related aspects of their respective worlds.
A possible plot could start with Naruto being transported to the world of the Seven Deadly Sins. There, he discovers his connection to Meliodas. They initially have some misunderstandings due to their different upbringings. But as they get to know each other, they realize they are brothers. Together, they embark on a journey to find their long - lost family and along the way, face various challenges from the demons and other antagonists in the Seven Deadly Sins world, all while Naruto tries to adapt to this new and strange world.
Yes, there are likely fanfictions out there with such a concept. Fanfiction writers often come up with creative and unexpected crossovers like this. You can search on popular fanfiction websites such as Archive of Our Own or FanFiction.net to find stories based on this idea.
A more complex plot idea could be that there is a prophecy about Naruto and Raven. As Naruto is the little brother, he is initially seen as the weaker one, but as the story progresses, he shows that he has unique qualities that are essential to fulfilling the prophecy. Along the way, they face many enemies who want to stop them from achieving the prophecy's goal. Their relationship evolves from a simple brother - sister bond to a powerful partnership that can change their world.
Well, I'm not sure about a specific 'Naruto brother of Meliodas' fanfiction that stands out above all others. It really depends on what you're looking for in a fanfic. If you like action - packed stories, you might find some that incorporate Naruto's ninja skills and Meliodas' demon powers in interesting ways. But you'll have to dig through the available fanfics to find the ones that suit your taste.
One possible plot could be that Naruto somehow gets the powers of Meliodas. He might start using Meliodas' sword techniques along with his own ninja skills. For example, he could combine the Rasengan with Meliodas' Full Counter move. And he may also inherit Meliodas' personality traits like his laid - back yet determined nature, which could lead to some interesting interactions with his friends in the Naruto universe.
Perhaps the Akatsuki members are using baccarat as a means to gather funds for their evil plans. Naruto and his team discover this and try to stop them by interfering with the baccarat games. They might have to learn the rules of the game quickly to be able to do so. The story could involve a lot of strategic battles within the context of the baccarat games, like using jutsus to affect the outcome of the card draws.
One possible plot could be that Naruto and Meliodas are brought to a strange new world together. They start off as rivals, each thinking their own way of fighting and protecting is superior. Naruto with his ninjutsu and Meliodas with his demon powers. But as they face common enemies in this new world, like some powerful dark magic - using villains, they gradually learn from each other. Naruto might teach Meliodas about the importance of friendship and teamwork in the way he values his comrades in Konoha. And Meliodas could show Naruto some unique combat techniques using his sword skills and demon forms. Eventually, they become friends and combine their powers to defeat the big bad and save the new world.
Well, a plot could involve the baby being a key to peace in their world. Meliodas and Elizabeth have to protect the baby from various threats. Maybe the baby has a special connection to an ancient prophecy. So they travel around, meeting different characters who either want to help or harm them because of the baby. It could also show their daily life as new parents, like dealing with sleepless nights and the baby's first steps.
A good plot could involve a misunderstanding between them. Maybe Diane overhears something that makes her think Meliodas doesn't care about her as much as she thought. This leads to her distancing herself from him, and Meliodas has to figure out what went wrong and win her back. It could show their different personalities and how they handle relationship issues.
One common theme could be the power struggle. Given that both Naruto and Meliodas are powerful in their own right, as brothers, they might face challenges related to controlling or using their powers together. Another theme could be loyalty, showing how they support each other through difficult times.
