The Naruto's merman bloodline can greatly impact his relationships. If we consider his relationship with the village elders, they might see him as a potential threat or an asset depending on how they view his new abilities. They could try to use him for their own purposes, like sending him on dangerous underwater missions. With his peers, some might envy his unique powers, while others could be inspired by him. And when it comes to his family - like relationship with Iruka - Iruka might worry about Naruto being in a world that doesn't fully accept his merman side and try to protect him while also encouraging him to embrace his new identity.
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.
The Uzumaki bloodline can also affect his relationships with characters from other villages. In fanfiction, ninja from other villages who know about the Uzumaki's power might either fear or respect Naruto more. This could lead to different diplomatic situations. For example, a village might be more willing to negotiate with the Hidden Leaf because of Naruto's Uzumaki bloodline. On the personal level, he might meet other Uzumaki descendants in other villages, and they could form a strong bond based on their shared bloodline.
In Naruto fanfiction with the Kaiju bloodline, it can have a huge impact on relationships. If a character has this bloodline, those who are power - hungry might try to use them or manipulate them for their own gain. This can lead to a lot of mistrust. However, among true friends, it could be a source of admiration. They might see the unique abilities as something that can protect the village and be proud of the character. Also, in romantic relationships, the Kaiju bloodline could be both a draw and a concern. A partner might be attracted to the power but also worried about the danger it brings.
With his friends like Sakura and Kakashi, they would be very curious. Sakura might try to study Naruto's Pokemon bloodline to understand how it works. Kakashi, on the other hand, would be more focused on how to train Naruto to control these new powers. It could bring them closer as they all try to figure out the implications of this new development in Naruto's abilities.
On the other hand, a unique bloodline ability could also bring characters closer. Say a character has a bloodline that allows them to communicate with animals. Another character who loves animals might be drawn to them and they could form a strong bond. They could then team up and use the bloodline ability in creative ways during missions.
If Naruto gets a new bloodline, his relationship with Sasuke could become even more complex. Sasuke might be jealous of Naruto's new power, or it could be a reason for them to team up again to explore the origin of the bloodline. With Sakura, she might see Naruto in a new light, either being more attracted to his new strength or being worried about the potential risks of the bloodline.
In Naruto fanfiction, the mind control bloodline can have a huge impact on character relationships. If a ninja uses the power to make another ninja do their bidding, it can lead to mistrust among their comrades. They might start to question who they can really trust. Moreover, if a character is mind - controlled into betraying their clan, they will face a lot of difficulty in being accepted back. Their family and friends will have to grapple with the fact that the betrayal wasn't entirely their fault, but still, there will be a sense of unease and a need to rebuild the relationship.
His malnourishment could make his friends worry more about him. For example, Sakura might start to be more motherly towards Naruto, constantly trying to get him to eat proper meals. His relationship with Sasuke could also change as Sasuke might initially look down on Naruto for being weak because of the malnourishment, but then as he sees Naruto's determination to overcome it, he gains a new respect for him.
One popular trope is the merman Naruto having enhanced underwater combat abilities. Since he has the merman bloodline, he can swim at incredible speeds and use water as a weapon more effectively. For example, he might be able to create powerful water currents or whirlpools with just a flick of his tail. Another trope could be the isolation aspect. Naruto, as a merman, might be shunned by some in the ninja world who don't understand his kind. This could lead to a story of him trying to prove his worth and find acceptance among his peers.
Well, in fanfiction, the Hiraishin bloodline could greatly enhance Naruto's speed. He could potentially use it to instantly appear in various places during battles, catching his enemies off - guard. It might also allow him to combine it with his existing jutsu, like the Rasengan, creating new and more powerful attacks.
