Naruto's understanding of the ninja world would deepen. With the new doujutsu, he could see things that were hidden from him before. This would make him more aware of the politics and power struggles in the ninja villages. He might start to question some of the long - held beliefs and traditions. He could also use his new insights to try and bring about positive change in the ninja world, like finding ways to end the cycle of hatred between different clans.

They might obtain new doujutsu powers through genetic experiments. In some fanfictions, evil scientists or rogue ninja might try to combine different bloodlines to create a new and powerful doujutsu. Another way is through a divine encounter. For example, a character could be blessed by a god - like entity in the Naruto universe and be given a new doujutsu power.

Naruto might become more serious. Deadshot is a very serious and focused character. So Naruto could lose some of his goofy and carefree nature and become more calculating in his actions.

His relationship with the older generations like Kakashi and Tsunade could shift. They would see Naruto as a more mature and capable ninja. Naruto could use the insights from his doujutsu to contribute more to the decision - making in the village, and they would respect his opinions more.
