In a Naruto controls glass fanfiction, his relationship with Sasuke could be affected in an interesting way. Sasuke might see Naruto's new power as a threat at first, or maybe as something he wants to surpass. This could create some tension between them. But as they face common enemies, Naruto could use his glass powers to save Sasuke's life. This would lead to a new level of understanding and respect between them. And his relationship with other villagers would also change. They would view him as even more of a hero and protector, which would make them more loyal to him.
It could strengthen his relationship with his friends. For example, they might be in awe of his new power and support him in mastering it. His friends could also help him find new ways to use the glass - controlling ability in battles.
His relationship with his sensei, like Kakashi, would also change. Kakashi would probably be more cautious and try to guide Naruto in using this power responsibly. Naruto's new power could also attract the attention of new characters, either those who want to use him for their own gain or those who want to help him master it. This would bring new dynamics to his relationships.
His relationship with Sasuke would become really complex. Sasuke, as an Uchiha, might feel a mix of jealousy and concern. Jealousy because Naruto now has a part of what makes the Uchiha special, and concern because he knows the dangers of the Sharingan. They might have more intense battles or training sessions as Sasuke tries to understand how Naruto got the Sharingan and how it's affecting him.
If Naruto got a new bloodline in the fanfiction, it could strengthen his relationship with Sasuke. Sasuke, always interested in power, might be intrigued by Naruto's new abilities and see him in a new light. They could start training together again to understand and master the bloodline, which would bring them closer as friends and rivals.
It would likely strain his relationship with Sasuke. Sasuke has his own complex history with Orochimaru, and if Naruto becomes a fan, Sasuke would be very confused and probably angry. He might see Naruto as betraying their shared values. As for his friends in Konoha, they would also be worried and try to talk Naruto out of it, which could lead to some arguments and a rift in their friendships.
For his friends in Team 7, Sakura would be initially shocked but then try to find medical ways to help Naruto if the tail causes any discomfort or problems. Naruto's new state might also attract the attention of Hinata, who would be even more shy around him but also very supportive. And with the villagers, those who once feared or hated him might start to see him in a new light as this unique development could be seen as a sign of his growing power and importance.
His power can make his relationships more complex. For example, if he uses time control to be with a friend more often, that friend might start to feel like Percy is being overbearing. On the other hand, it could strengthen his relationships. He could save a loved one from a dangerous situation in the past, which would deepen their bond.
In a Naruto finds ancient technology fanfiction, his relationship with his sensei, like Kakashi, could be affected in an interesting way. Kakashi would be both proud of Naruto for the discovery but also cautious. He would guide Naruto in understanding the technology. This would create a new dynamic in their relationship, with Naruto relying more on Kakashi's wisdom and Kakashi having more faith in Naruto's judgment as he deals with this new and powerful discovery.

It might also make Sasuke more protective of Naruto in a strange way, since the Sharingan is precious to the Uchiha.
His relationship with Sasuke would be greatly affected. Sasuke might initially be confused or even a bit jealous of Naruto's new form and powers. But as they face challenges together, they would learn to work with Naruto's Pokemon - like abilities. For example, if Naruto could fly as a certain Pokemon, he could help Sasuke in battles in new ways.
His friends might be a bit wary at first. But if Naruto uses his powers for good, like saving them from danger, they would accept him more. His relationship with Sasuke could change too. Sasuke might see Naruto's new powers as a threat or as something to strive for in terms of power.
