He would likely be adapted as a very powerful and mysterious character. His skills in the Naruto universe would translate into some sort of special magical abilities in the Harry Potter world. For example, his Sharingan could be like a super - powerful magical eye that gives him unique insights.
Itachi would probably be very calm and composed. He might see Sarada as a symbol of the new generation of ninjas in the village. He could be gentle with her, perhaps sensing her potential and her desire to grow as a ninja.
He could also develop through facing new threats in the RWBY world. The Grimm are different from his usual opponents in Naruto. Dealing with them might force him to adapt his combat style and in turn, grow as a character. For instance, he might have to rely more on others' skills in a team - based RWBY battle scenario.
His possessiveness could be seen in his actions towards Sakura. He may be overly protective, like not allowing her to go on dangerous missions alone. He would always want to be the one to accompany her, ensuring her safety at all times. This shows that he doesn't want to share her with any potential threats that could come her way during a mission.
Their relationship would likely become more trusting. In marriage, they would have to rely on each other more. For example, Itachi might open up more about his missions and the secrets he has been keeping.
Their relationship would deepen. Itachi becoming Hokage would mean that Naruto has someone he truly admires in the highest position. Naruto would be more eager to prove himself worthy in Itachi's eyes. Itachi, on the other hand, would see Naruto as a symbol of hope and the future of the village. They would likely have private conversations about the future of Konoha, with Itachi sharing his long - term plans and Naruto providing his unique perspective based on his own experiences. This would create a bond that is not just based on respect but also on a shared vision for the village.
To create a compelling female Itachi from Kumo, first give her unique physical traits. Maybe she has long white hair with a blue tint, which is different from the original Itachi's but still gives an air of mystery. Then, give her a strong sense of honor like Itachi. For example, she always keeps her word, even if it's difficult. Also, give her a special ability, like the ability to control ice - based ninjutsu in a way that no one else can.
The meeting could start with a sense of mystery. Itachi might appear out of nowhere in Korra's world. Korra, sensing his strange energy, would be on guard. Itachi would be sizing her up, taking in her appearance and the power he can sense within her. They might exchange a few words, with Itachi's soft - spoken nature contrasting with Korra's more direct way of speaking. As they start to interact more, they would begin to learn about each other's abilities and the worlds they come from.
Their relationship could be developed through a series of flashbacks. For instance, Itachi could recall moments from Naruto's childhood that he observed while in the ANBU. These memories could make him see Naruto in a new light. Meanwhile, Naruto could learn about Itachi's past and the sacrifices he made. This exchange of knowledge could build a bond between them based on empathy and respect. In addition, they could train together in secret, with Itachi teaching Naruto some of his ANBU skills, which would also strengthen their relationship.
His character could be developed by showing his adjustment to the Fairy Tail world. He could start off as a loner, but gradually open up to the members. His backstory as a ninja could be explored further in relation to the new environment, like how his past actions affect his new relationships.
