Naruto could prank the Hyuuga by changing the signs on their training areas. So instead of the correct instructions for their Gentle Fist training, there are completely wrong and silly ones. This would disrupt their training sessions and lead to some really funny moments as the Hyuuga try to figure out what went wrong.
In a Naruto pranks Hyuuga fanfiction, Naruto could use his knowledge of the Hyuuga's strict diet to play a prank. He could replace their healthy and traditional Hyuuga food with really spicy or overly sweet treats. The Hyuuga, who are used to a very specific diet, would be in for a shock when they take a bite. This would be a simple yet effective prank that would bring out some interesting reactions from the proud Hyuuga clan.
In a Naruto pranks Hyuuga fanfiction, Naruto might use his typical mischievous tactics. For example, he could use his shadow clone jutsu to create chaos around the Hyuuga compound.

It would be a really funny scenario as the serious Hyuuga clan tries to deal with Naruto's antics.
Well, Naruto could use his shadow clone jutsu to create chaos. Maybe he makes clones that keep changing Ibiki's paperwork into funny pictures. That would surely annoy Ibiki a great deal.
In this fanfiction, Naruto might use his shadow clones to create chaos at the Anbu headquarters. He could make it seem like there are intruders everywhere, causing the Anbu to go on high alert and run around in confusion. Maybe he'll also replace some important documents with funny pictures or put whoopee cushions on their chairs.
Well, in such a fanfiction, Naruto might learn different skills. Maybe he'd be trained in the Hyuuga's Gentle Fist style. This could make him a more versatile fighter, combining his own Uzumaki tenacity with the precision of the Hyuuga techniques.
If Naruto was adopted by the Hyuuga in fanfiction, it would be a game - changer. Firstly, he would be under the protection of a powerful clan. The Hyuuga could provide him with better living conditions and more resources for his growth. Naruto could learn from the Hyuuga elders, who have a wealth of knowledge. In terms of his relationships, he would become a part of the Hyuuga family tree. This could lead to some interesting storylines, like potential arranged marriages or new rivalries within the clan. His ninja training would also take a new turn as he incorporates Hyuuga techniques into his fighting style.
In this kind of fanfiction, Naruto might gain access to the Hyuuga's unique fighting techniques. For example, he could start learning the Gentle Fist style. This would make him an even more formidable ninja. He might also be exposed to the Hyuuga's clan politics and traditions, which could be a whole new world for him compared to his life as an orphan in the original story.
In such a fanfiction, they might be on a team to solve a mystery. The Hyuuga's ability to see chakra could help in detecting any hidden or magical entities that are causing problems. Harry, with his knowledge of the wizarding world, could contribute spells to deal with magical barriers or curses. They would need to overcome their cultural differences first. Harry is used to the rules and etiquettes of the wizarding society, while the Hyuuga has its own set of ninja traditions.
Naruto could enlist the help of his friends like Shikamaru. Shikamaru could come up with a really elaborate plan. For example, they could set up a fake mission where Ibiki thinks he's in charge, but it's all just a setup for a series of pranks. They could have actors pretending to be enemy ninjas who act really silly instead of being threatening. And Naruto could keep popping up in unexpected places during this 'mission' to further annoy Ibiki.
Well, Danny could use his ghostly powers to play all sorts of tricks on the Justice League members. Maybe he turns Superman invisible for a while just to see his confusion. Or he makes Batman's utility belt float away when he's in the middle of a fight.
One of the funniest pranks could be that the Kyuubi makes Naruto's clones start singing cheesy pop songs instead of following his commands. Naruto often uses his clones in battles and for various tasks. So when he sends them to attack an enemy, they all start singing and dancing instead. This would not only be a shock to Naruto but also to his opponents. Another great prank would be the Kyuubi making Naruto's body move in the opposite direction of what he wants. So when he tries to jump forward, he jumps backward instead, leading to all sorts of comical situations.
