In Naruto and Hiashi fanfiction, Naruto and Hiashi are the central figures. Naruto is often depicted as the catalyst for change or a source of new ideas in these stories. Hiashi represents the traditional values and power of the Hyuga clan. Sometimes, other characters from the Naruto universe might also be involved, like Hinata, who is Hiashi's daughter and has her own connection to Naruto. But overall, Naruto and Hiashi are the main focus, with their interactions driving the plot forward, whether it's about mending clan relations, fighting a common enemy, or exploring new ninja techniques.
One possible motive could be a misunderstanding. Maybe Hiashi mistakes Naruto for an enemy who has infiltrated the village in disguise. Another reason could be related to clan politics. If Naruto somehow gets involved in a situation that threatens Hiashi's clan interests, Hiashi might take extreme measures.
Hiashi could be initially skeptical. Naruto has a reputation for being a bit of a troublemaker at times. But if Naruto presents a good case, Hiashi might warm up to the idea. For instance, if Naruto shows how his actions would bring honor and prosperity to the Hyuga clan.
One interesting Naruto and Hiashi fanfiction could be about Hiashi training Naruto in some secret Hyuga techniques. Maybe Naruto has to prove himself to Hiashi first, and through a series of trials, they form an unlikely bond.
Well, it could be about Naruto growing up in the Hyuga clan. Maybe he discovers his true parentage early on and has to deal with the expectations and politics of the clan. He might learn the Gentle Fist technique in a different way than Neji or Hinata.
One possible plot could be that Naruto gains a whole new family structure. Hiashi might train Naruto in the ways of the Hyuga clan, which could make Naruto an even more formidable ninja. He would also be exposed to the Hyuga's strict traditions and might have a different view on the ninja world. Maybe he'd form a closer bond with Hinata earlier as they'd be siblings in this scenario.
Perhaps in this fanfiction, Naruto meets Hiashi during a time of crisis in the Hidden Leaf Village. Hiashi, being an elder and a respected figure, is involved in the village's defense plans. Naruto, eager to help, wants to be part of the action. Hiashi initially doubts Naruto's abilities but is soon proven wrong. They then work side by side, with Naruto's Uzumaki chakra and Hiashi's Hyuga skills combining to create a powerful defense against the enemy.
Maybe Hiashi adopts Naruto because he realizes that Naruto is a key to uniting the village. As Naruto becomes part of the Hyuga family, he starts to influence the clan's view on outsiders. He might introduce some new training methods that he learned from Jiraiya. Naruto could also have a role in protecting the Hyuga's secrets, like the Byakugan. He would grow in a different environment, and this would change his relationships with characters like Sasuke and Sakura in new and unexpected ways.
In this fanfic, Naruto might save Hiashi in a battle situation. Maybe Hiashi is facing a powerful enemy that he can't handle alone, and Naruto steps in with his strong ninja skills. For example, if Hiashi is being attacked by a group of rogue ninjas, Naruto could use his Rasengan to fend them off.
One interesting plot could be that Hiashi discovers Naruto has some hidden connection to the Hyuga clan. This would make Hiashi take a special interest in Naruto, and he might start training Naruto in Hyuga - related skills.
In some fanfictions, Naruto might use his newfound jutsu skills. He could quickly dash in between Hiashi and Hinata, using his speed and agility to block any attacks Hiashi might be launching towards Hinata. His Rasengan in his hand, ready to defend if Hiashi doesn't back down. This shows Naruto's determination to protect Hinata from any harm, even from her own father in this fictional scenario.
