Naruto's understanding of different forms of power would expand. The Kamehameha is based on ki energy, which is different from chakra. This would make him more open - minded about other types of energy and power sources. He might start to explore if there are ways to combine chakra and ki, which could lead to him developing entirely new jutsus. This exploration could also make him more respected among the ninja community as a pioneer of new power - combining techniques.
Naruto could become more confident. Since Horus is a powerful and respected figure in Egyptian mythology, being his son would give Naruto a sense of self - worth. He might start to act more like a leader, inspiring others with his new - found identity. His fighting style could also change. Instead of relying solely on his regular ninja techniques, he would incorporate his Horus - given powers, like enhanced speed or the ability to see far distances.
Naruto's character would grow in terms of his power understanding. The Kamehameha is a very different type of attack from what he's used to in the ninja world. So, he'd have to study it, understand its mechanics, and this would make him more of a strategic thinker. He might also start to explore other non - ninja techniques, which could change his whole approach to combat and protecting his village. He could become more open - minded about different forms of power, not just relying on chakra - based jutsu.
Naruto's character could develop in terms of his leadership skills. In the DxD universe, there are complex power structures and political situations. By being involved in the events there, Naruto could learn different leadership styles and apply them to his own way of leading. He could also develop his understanding of friendship and loyalty in a new context. For example, when facing enemies with the Rider or Caster, he might have to make tough decisions about who to trust and how far he's willing to go to protect his new allies, which would all contribute to his character growth.
One way could be through a powerful curse. Maybe a dark ninja places a curse on Naruto that slowly corrupts his mind. Another way might be extreme betrayal. If the village he loves turns on him for no good reason, he could snap and turn evil.
She could gain new powers or abilities. In the Naruto universe, there are many different forms of power. Maybe she could learn some basic ninjutsu or even develop a new form of her Maiden powers by combining it with chakra. This would not only change her combat capabilities but also her character as she becomes more powerful and has to handle this newfound strength in a different way compared to RWBY.
Perhaps a powerful villain has the ability to combine different powers from different universes. This villain targets Naruto and in the process of fighting against this threat, Naruto somehow absorbs the knowledge of the Kamehameha. He then has to figure out how to use it in his own ninja - style way.
The son could be developed as a very determined character. Since he grows up with a banished father, he might have a strong desire to change the situation. He could be skilled in both physical and mental aspects, like being an excellent fighter and also having great strategic thinking, just like Naruto.
The half - brother could be developed as a character with a troubled past. He might have been ostracized in his own community because of his relation to Naruto or his own unique abilities. This could make him initially cold and distant but as he interacts with Naruto, he could gradually open up and become more warm - hearted.
In Naruto peace fanfiction, his character could be developed by exploring his role as a teacher. He could train a new generation of ninjas, instilling in them the values of peace and cooperation. He would have to adapt his teaching methods to different learning styles, which would also show his growth as a person and a leader.
Naruto could develop by learning to control the new powers of Shazam. He might start off clumsy but gradually master them. For instance, at first, he might accidentally break things with his newfound strength, but then he'd learn to be more precise.
