In the fanfic, their relationship could progress in a rather unconventional way. Given Naruto's godlike status, he might not fully understand the nuances of Amanda's world at first. But as he tries to fit in and learn more about her, they start to bond. They could go through various challenges together, like facing a powerful enemy in Amanda's world. During these challenges, they learn to trust each other completely. Naruto might use his powers in creative ways to protect Amanda, and she might use her knowledge to help him adapt. This mutual reliance and the experiences they share would cause their relationship to grow into a romantic one.
Naruto would probably be very enthusiastic and curious about Amanda Holliday. He'd be constantly asking her questions about her world and all the cool gadgets she has. Amanda, on the other hand, would be intrigued by Naruto's ninja abilities. She might ask him to show off some jutsus. They'd likely bond over their shared sense of adventure and their determination to face any challenges that come their way.
One possibility could be that Naruto, with his godlike powers, arrives in Amanda Holliday's world. They first meet when Naruto is exploring the new environment and is drawn to Amanda's unique skills in her field. Their relationship could start with mutual curiosity, as Naruto's extraordinary abilities fascinate Amanda, and her tenacity and knowledge intrigue him.
It could start with Naruto being in a new realm of power, and Deathstroke somehow getting involved in his training. Maybe Naruto is seeking new challenges and Deathstroke offers his expertise. Then, they would start with basic combat training, with Deathstroke pushing Naruto to his limits. As the story progresses, they might face common enemies that require both of their skills to defeat. And Naruto would gradually incorporate Deathstroke's teachings into his own fighting style.
Well, a plot could involve Amanda Holliday being curious about Naruto's world. So Naruto takes her to the Hidden Leaf Village. There, she gets to experience the ninja way of life, like training at the ninja academy and seeing how the village is run. In return, Naruto goes to Amanda's place and learns about advanced technology. They then combine their knowledge and skills to protect both of their worlds from a threat that wants to destroy all forms of unique cultures and powers.
His godlike status could have a big impact. On one hand, it could make Ayame feel protected. Naruto can use his powers to keep her safe from any danger. However, it might also attract unwanted attention to Ayame. People might target her to get to Naruto. But Naruto would do everything in his power to keep her safe, which would strengthen their bond in the face of adversity.
Their relationship could develop through mutual respect. Naruto, with his godlike status, would respect Yugito's strength and independence. Yugito, in turn, would admire Naruto's power and his kind heart. They would support each other in their ninja duties and grow closer as they face challenges together.
Their relationship could develop into a strong partnership. Since they both have godlike powers, they understand each other's struggles and responsibilities better. They might start training together more often, sharing new techniques and strategies. This would lead to a deep respect for each other's abilities and a closer bond.
It would depend on the writer's intention. If the focus is on Naruto's growth, he could start exploring new jutsu or forms of chakra control. Since he was revived by Madara, there might be some dark elements associated with his revival that he has to overcome. Maybe he has to fight off some sort of curse that came with the revival process. And he would have to do this while still trying to protect the people he cares about.
Naruto's character would likely become more serious and focused. As an ANBU captain, he has a lot of responsibility. His godlike powers might make him a bit more reserved as he realizes how much more powerful he is than others. He would also become more strategic in his thinking, using his powers in creative ways to achieve his goals.
Naruto might become more brooding. The dark training from Darkseid could make him less of the cheerful, optimistic Naruto we know. He may be more secretive about his new powers and training.
