In some fanfictions, their relationship might develop due to a prophecy. There could be an ancient prophecy that foretells the union of Naruto and Tiamat as the key to saving multiple universes. At first, they might be reluctant to believe it, but as events unfold and they see the signs, they start to consider the possibility. This leads them to explore their relationship further, and eventually fall in love as they fulfill the prophecy's requirements.
In Naruto maries Tiamat fanfiction, perhaps there could be a focus on the political implications. If Naruto, who is a hero in his own world, marries Tiamat, it could change the power dynamics between different villages. Allies might become more eager to strengthen their bonds with Naruto's village, fearing the new power that the union brings. Enemies, on the other hand, might form new alliances to counter this potential threat.
Naruto might be initially in awe of Tiamat's powers. Given his curious nature, he would likely try to understand how they work. He could attempt to adapt some of her power - using techniques into his own ninja fighting style.
Yes, there are quite a few. You can check out some fanfiction platforms like FanFiction.net or Archive of Our Own. Just search for 'Naruto and Tiamat' and you'll find a variety of stories with different plotlines and interpretations.
One common theme could be power struggles. Since Naruto has his own set of powers and Tiamat is often depicted as a very powerful being, there could be a lot of tension regarding who is more powerful and how they interact in terms of power. Another theme might be the clash of different cultures or mythologies, as Naruto is from a ninja - based world and Tiamat has her own origin in different mythologies.
One idea could be that Naruto somehow gets transported to the world where Tiamat exists. He has to use his ninja skills to survive in a completely different and magical realm. Maybe he teams up with local heroes to face a threat that Tiamat also has an interest in.
The guild's acceptance of Tiamat would likely be a mixed bag. Some of the more adventurous and powerful members like Gildarts might be more open to having Tiamat around. They would see the potential benefits of having such a powerful ally. However, the younger or more timid members could be very hesitant. They might be worried about Tiamat's true intentions or its power getting out of control.
Tiamat is significant in fanfiction as she represents a primeval and powerful force. Her presence can add a sense of mystery and danger. In many stories, she serves as an antagonist, driving the plot forward as the heroes must find a way to either defeat or appease her.
Tiamat could be developed further by exploring her relationships with other characters. For instance, if she starts to mentor a young character, it would show a different side of her. She could teach them about her powers and the history of her kind.
First, you need to understand the characteristics of each universe. For Highschool DxD, know the different devil clans, their powers and hierarchies. In Naruto, study the ninja villages, jutsus and the chakra system. For Tiamat, research her origin and abilities. Then, create a plot that can bring these elements together. It could be a quest to save a world, or a tournament where characters from all three universes participate.
