Perhaps it's the love for both franchises. Someone who is a big fan of both 'Harry Potter' and 'Kingdom Hearts' might have wanted to see how the characters and concepts from the two could interact. Maybe they saw some similarities in the magical or fantastical elements and thought it would be interesting to create a crossover.
The inspiration could come from a desire to explore new and unique storylines. 'Harry Potter' has a lot of complex characters and a rich magical world, and 'Kingdom Hearts' has its own set of interesting characters like xemnas. By combining them, the author of the fanfiction might be trying to create a story that has the best of both worlds. They could be thinking about how Harry Potter's journey could be different if it was set in the context of Kingdom Hearts' universe or how xemnas would interact with the characters from Harry Potter. It could also be a way to add a new twist to the well - known 'Harry Potter' story.
It could be that the fan was looking for a way to break the boundaries between different fictional universes. 'Harry Potter' and 'Kingdom Hearts' are both very different in terms of their settings, but they do share some common elements like magic and battles against dark forces. The idea of Harry Potter being part of a Kingdom Hearts - like fanfiction with xemnas might have come from a need to see how the rules and characters from both would mesh. For example, how would Harry's magic work in the Kingdom Hearts world? And how would xemnas view Harry as a character? This kind of crossover can open up a whole new world of possibilities for storytelling and character development.
I'm not sure if it's a very popular concept. 'Harry Potter' and 'Kingdom Hearts' are two very different franchises, and creating a fanfiction that combines them in such a way might be quite niche. It could be something that only a small group of fans who are really into both universes might explore.
Well, Sora and his friends would most likely start a rescue mission. They would search through different worlds looking for any clues as to where Xemnas has taken Kari. Donald and Goofy would be right by Sora's side, with their unique abilities to help. They might encounter some of Xemnas' minions along the way and have to fight them to get closer to Kari.
In a fanfiction, perhaps Kari is a friend of Sora and the others. Xemnas kidnaps her to use as bait to lure Sora into a trap. He knows that Sora will come to save Kari. Xemnas could be thinking that by capturing Sora as well, he can finally achieve his goal of obtaining Kingdom Hearts. So, Kari becomes an important piece in his evil plan.
You can start by looking on fanfiction platforms like Archive of Our Own (AO3) or FanFiction.net. Just search for 'Kingdom Hearts Xemnas Saix' on their search bars, and you'll likely find a variety of fanfictions involving these characters.
Sora would be furious. He'd immediately set out to find Xemnas and rescue Kairi without hesitation.
Well, it could be just pure creativity. Maybe a fan wanted to see what would happen if the magic of Harry Potter was combined with the unique bond between a human and a dragon like Toothless. It might also be inspired by a love for both franchises and a desire to create something completely new and unexpected.
The inspiration might be the desire to blend two popular fictional characters. Both Harry Potter and Loki are quite popular. Fans might be interested in seeing how the magic of Harry Potter's world would interact with Loki's mischievous and powerful nature.
Perhaps the creator of such fanfiction was interested in exploring the contrast between good (as represented in Harry Potter) and evil (as Belphegor is often seen in some interpretations). They might want to see how the characters and world of Harry Potter would react if there was an intrusion of a figure like Belphegor. It could also be just a wild creative idea from a fan who loves both Harry Potter and stories related to Belphegor and just wanted to mash them together to see what would happen.
One great 'Kingdom Hearts Xemnas x Reader' fanfiction is 'A Dark Bond'. It delves deep into the relationship between the reader and Xemnas. The story is filled with emotional moments as the reader tries to understand Xemnas's complex nature. Another one is 'Xemnas's Redemption'. Here, the story takes an interesting turn where Xemnas starts to question his actions because of the reader's influence.
In a fanfiction scenario where Xemnas kidnaps Kairi, it could lead to a great adventure for Sora and his friends to rescue her. Sora would likely be filled with determination and rage, fueling his journey to face Xemnas once again. The story could explore the dark realm where Kairi is held captive, perhaps with new and dangerous Heartless created by Xemnas.
