When writing their interactions, consider the power dynamics. Naruto has his own strong abilities, but Nagato's Rinnegan gives her great power too. They could have sparring sessions that turn into deep conversations. Maybe Naruto gets the upper hand in a fight, and instead of being angry, Nagato is impressed by his growth and they start to bond over their mutual respect for each other's strength. Also, don't forget to include small details like their facial expressions and body language during their interactions. For instance, Naruto might grin widely when trying to cheer up Nagato, while Nagato might initially look away, but then slowly start to engage.
He could be more light - hearted. Instead of being burdened by his past immediately, he might start off with a more positive outlook. For instance, he could be curious about the new world around him and approach things with a sense of wonder.
You can also write about their emotional interactions. Maybe Luffy has a moment of self - doubt during their journey, and Marco, being the older and more experienced one, offers words of encouragement. He could share some of his own past experiences of facing difficulties. In return, Luffy's positive energy and unwavering belief in her goals could inspire Marco to look at things from a different perspective. This kind of mutual influence can be a great part of their character interactions.
In some fanfictions, Naruto and Nagato might be related through their shared experiences with the ninja world. They both faced great tragedies. Naruto could be seen as a successor to Nagato's ideals in a way. Nagato once wanted peace through force, but Naruto shows that peace can be achieved through understanding and forgiveness.
To write their character interactions well, first understand their personalities. Naruto is known for his optimism and determination. The Mizukage, depending on which one, is often a strong - willed and powerful leader. Start with a situation that forces them to interact, like a joint mission. Let Naruto's enthusiasm clash a bit with the Mizukage's more reserved nature at first. Then, as they face challenges together, show how they start to respect each other. For example, Naruto could be amazed by the Mizukage's strategic thinking, and the Mizukage could be impressed by Naruto's never - give - up attitude.
When writing their character interactions, show Hinata's shyness yet determination. For example, when she first approaches Demon Naruto, she might stutter a bit but still firmly state her intention to help or be by his side. Naruto, in his demon form, could initially be more brash and protective. He might growl at her at first, thinking he's a danger to her, but then slowly warm up as he realizes her sincerity.
Naruto's character could become more conflicted. He has always been about hope and friendship, but being related to Nagato might make him question his own beliefs. He might start to see the world in a more nuanced way, understanding that there are reasons behind Nagato's actions that he previously didn't fully consider.
Naruto might be more brooding. Since Nagato had a rather tragic past, Naruto could inherit some of that darkness. He may not be as openly optimistic as in the original story.
Nagato, in fanfiction, can be depicted in various ways. Some may show him as a more conflicted character. He has his own beliefs which were shaped by his experiences, like the death of his friends and the destruction he witnessed. He may be more hesitant to change compared to Naruto, but also has the potential for redemption which makes his character interesting.
In these fanfics, Nagato may help Naruto on an ideological level. Nagato once believed in a very different way of achieving peace. By sharing his journey and how he came to realize the flaws in his thinking, he can guide Naruto in his pursuit of true peace. Nagato could also use his influence over the Akatsuki remnants to prevent them from causing more chaos, which in turn helps Naruto in his mission to protect the ninja world.
One possibility is that there was some sort of spiritual or chakra - based connection between Naruto and Nagato. Nagato, being the possessor of the Rinnegan, recognized Naruto's strong will and the fact that he was on a path to change the ninja world for the better. Through this connection, Nagato was able to transfer the power of the Rinnegan to Naruto. It could also be related to the nature of the Sage of Six Paths' power that was somehow involved in this transfer, as both Naruto and Nagato were related to the Sage in different ways.
