In a fanfiction where Naruto is Rias' brother (brocon), what new powers could Naruto gain?

In a fanfiction where Naruto is Rias' brother, the Naruto storyline would be altered significantly. Naruto's nature as a person might change due to the influence of the devil society. He may become more sly or strategic in the way devils are. His fighting style could incorporate more magic - like elements from the DxD world. His backstory would now involve being part of a devil family. His relationships with his friends in the Naruto world would be less prominent as he'd be more involved with the devils. For example, instead of going on missions in the ninja world, he'd be involved in devil - related tasks to protect his sister and their family's status.

A simple idea for the fanfiction could be that the brother, due to his weak body, is always in the shadow of Rias. His 'brocon' nature makes him extremely possessive of her. Naruto, being the outsider, initially doesn't understand this dynamic. But as he gets to know them, he tries to make the brother see that he can have his own identity and purpose, even with his physical limitations. He could encourage the brother to find his own strengths, like intelligence or strategy, rather than just relying on his relationship with Rias.

In this fanfiction, the brother's 'brocon' nature towards Rias could be a complex aspect. He might be overprotective because of his weak body, feeling that he has to be the one to look after his strong sister in some way. Naruto could come into the picture and show him that strength isn't just about physical power. For example, Naruto's willpower and determination are things the brother could learn from. He could start seeing that his sister values strength in different forms too, and this realization could help him grow out of his overly 'brocon' behavior and focus on his own self - improvement.

He might gain a more powerful form of Rasengan, like a Rasengan that can change its shape and properties according to the situation. Maybe he has better control over his Nine - Tails chakra and can use it in more creative ways without losing control.

One possible plotline could be that Rias' brother has a brocon (brother complex) and is overly protective of her. In the Naruto world, perhaps they get involved in a mission together where Naruto also has to work with them. Rias' brother might constantly be trying to keep Naruto at a distance from his sister because he's so possessive. This could lead to some comical misunderstandings as Naruto is just being friendly.

Yes, there might be some fanfiction exploring such a unique crossover concept. In the world of fanfiction, writers often come up with creative and unexpected relationships between characters from different series. They might do this to create new storylines, explore different character dynamics, and engage readers who are fans of both 'Naruto' and the series where Rias is from (presumably 'High School DxD').

Another ability Naruto could gain is a deeper understanding of genjutsu. Shisui was very proficient in genjutsu, especially with his Sharingan. Naruto, being his brother, could have a natural aptitude for genjutsu. He could learn to break through stronger genjutsu more easily and also use more advanced genjutsu himself. This would be a significant change as Naruto was not originally known for his genjutsu skills, but with this new connection, he could become a more well - rounded ninja.

At first, Rias' brother would see Naruto as a threat to his relationship with his sister. But as time goes on, if Naruto shows that he has no romantic intentions towards Rias and is just a friend, the brother might start to warm up to him. Rias would appreciate Naruto for being able to handle her brother's brocon behavior better than others. And Naruto would just be his usual friendly self, gradually becoming part of their little group.

Naruto could potentially gain the power of mind - reading magic. This would be a huge advantage in both the wizarding war and in his interactions within Konoha. He could also gain the ability to transform into magical creatures, which would give him new forms of attack and defense. Another possibility is that he gains the power to nullify magic, which would make him a key player in the fight against wizards who use dark magic.

Naruto would gain some really cool (pun intended) new abilities. The ice - making ability would be the most prominent. He could form ice clones, similar to his shadow clones but with the added advantage of being made of ice and potentially having more durability. His sensory abilities might also be enhanced, as Esdeath has a good sense of her surroundings when using her powers. He could detect enemies hidden in the ice or snow. And, like I said before, the time - freezing power. This would allow him to analyze his opponents' moves during the frozen time and come up with the perfect counter - attack. It would add a whole new dimension to his combat skills.
