One way to develop their relationship is through a series of difficult conversations. Given their different backgrounds and the history between the Uzumaki and Uchiha clans, there are bound to be misunderstandings. By having honest conversations about things like the Uchiha massacre, Naruto's status as an orphan, and Fugaku's role in the Uchiha clan, they can start to break down barriers. Additionally, if there are situations where Naruto has to protect Fugaku's family members or Fugaku has to support Naruto in a village - wide crisis, it will show their loyalty to each other and further develop their relationship.
One possible plot could be Naruto growing up within the Uchiha clan. He might face unique challenges as the son of Fugaku, like dealing with the clan's expectations and the shadow of the Sharingan. He could also have a different relationship with Sasuke, perhaps as a brother figure, which would greatly change the dynamics of their interactions in the original story.
Yes, there are quite a few. You can check out some popular fanfiction websites like FanFiction.net or Archive of Our Own. Some of these fanfictions might offer unique takes on Naruto being the son of Mikoto and Fugaku, exploring different character relationships and plot developments.
One popular 'fugaku adopts naruto' fanfiction might be the one where Fugaku discovers Naruto's potential early on. In this story, Fugaku takes Naruto under his wing, training him in the ways of the Uchiha. This changes Naruto's life completely as he now has the support and training of one of the most powerful clans in Konoha.
Naruto would likely be more reserved in this fanfiction. Growing up in the Uchiha clan, he would be influenced by their more stoic nature. He might not be as loud and boisterous as in the original story. Also, he would have an in - depth knowledge of Uchiha traditions and values from an early age.
One common theme is the clash of different worlds. Since the reader is often from a different perspective or even a different 'world' in a sense, and Fugaku is from the Naruto universe with its own set of rules and values, there's often a lot of exploration of how they bridge that gap.
One possible plot could be Naruto growing up with a different set of family dynamics. Since Fugaku is from the Uchiha clan and Kushina from Uzumaki, Naruto might have a unique combination of powers from both clans. He could face different challenges in the ninja world, such as dealing with the Uchiha's legacy of the Sharingan and the Uzumaki's sealing techniques. Also, his relationships with other characters like Sasuke would be different as they would be more like family in this scenario.
It could also be Madara Uchiha, especially if the fanfiction involves time - travel or alternate timelines. Madara has his own plans for the Uchiha clan and the world, and he might not want Naruto interfering with his grand scheme while also being wary of Fugaku's actions.
It's appealing because it gives Naruto a different family dynamic. Instead of being alone, he has the support of the Uchiha clan through Fugaku. This changes his growth and development in an interesting way.
He'd be more confident. Growing up with Fugaku and Kushina, he'd have a strong family support system. He wouldn't have the same insecurities as in the original story. He might also be more of a natural leader, inheriting Fugaku's leadership skills from the Uchiha clan and Kushina's strong spirit.
