Their relationship could be shown as a source of strength. In the face of the new and dangerous situations in the Power Rangers' world, Naruto and Hinata would rely on each other. Naruto would be more protective of Hinata, and Hinata would be Naruto's calm and supportive partner. For example, when facing a powerful enemy, Naruto would charge forward while Hinata would use her Byakugan to analyze the situation and give Naruto advice.
The relationship could be portrayed as a more harmonious unity. Instead of two separate individuals with different dynamics, the fusion could represent a perfect blend of their relationship. They could be shown as having a single, unified goal in the story, which is a departure from their individual goals in the original Naruto series. This could be something like protecting the entire ninja world in a more inclusive and efficient way, using their combined strengths and insights.
The parents' relationship could also set an example for Naruto and Hinata. If Kushina and Hinata's mother had a strong, loving relationship, Hinata might be more inspired to be as loving and supportive in her relationship with Naruto. Similarly, Naruto could learn from his father's respect for Hinata's family and carry that forward in his relationship with Hinata.
Their relationship would likely deepen. They would have more private time together, sharing their dreams and fears at night. Naruto would become more protective of Hinata in their shared home.
The relationship would likely become more intimate. They'd have more time to just be with each other, sharing their thoughts and feelings without any rush. For example, they could have long conversations at night before going to sleep.
In such a fanfiction, the relationship between Naruto and Kushina would be one of mother - son love and mutual respect. Kushina would be protective of Naruto and proud of the man he has become. Naruto would look up to Kushina and value her wisdom. With Hinata, Naruto's relationship would be that of a loving couple. Hinata would support Naruto in all his endeavors. When it comes to Kushina and Hinata, Kushina would likely see Hinata as a worthy partner for Naruto and Hinata would respect Kushina for being Naruto's mother and a strong kunoichi.
Often, it's portrayed as very loving. Naruto is shown as being extremely protective of Hinata and their family. He values Hinata's opinions and often asks for her advice on village matters.
Hinata might be shocked at first. She has always adored Naruto, and this sudden act of aggression from him would leave her stunned and unable to process it immediately.
Their relationship would likely deepen as they face the responsibilities of being Uzukage together. They'd support each other through tough decisions. For example, Naruto might rely on Hinata's intuition when dealing with village politics. Hinata, in turn, would be more confident with Naruto by her side. They'd also have more time to understand each other on a deeper level, away from the chaos of their earlier adventures.
In the beginning, Naruto might be just focused on his job of protecting Hinata. However, Hinata's determination and courage in the face of danger, which she might show from time to time, would start to earn Naruto's respect. As they face various challenges together, Naruto and Hinata would start to bond. They might have late - night conversations about their dreams and fears. Hinata would learn to be more assertive from Naruto, and Naruto would learn to be more in touch with his emotions from Hinata. This mutual growth would lead to a very special and deep relationship between them.
Sakura's jealousy of Hinata can be portrayed in a more subtle way too. In some fanfictions, she might distance herself from Naruto when she sees Hinata getting closer to him. Instead of showing her jealousy outwardly, she'll withdraw and become more focused on her training or other friendships. But it's clear to the readers that she's jealous because of the way she'll steal glances at Naruto and Hinata when they're together, and the sad look in her eyes when she does so.
