What could be the plot of a 'Harry Potter plays Kingdom Hearts' fanfiction?

One possible plot could be that the Heartless somehow find their way into the wizarding world of Harry Potter. Harry and his friends initially mistake them for some new dark magic creatures. As they investigate, they discover that the Heartless are connected to a strange new threat that is draining the magic essence from the wizarding world, similar to how they seek hearts in Kingdom Hearts. Harry then has to use his knowledge of magic and work with some characters who might have knowledge of the Heartless from the Kingdom Hearts universe to stop this new evil.

No. Harry Potter is a distinct and original wizarding world created by J.K. Rowling, with its own unique characters, storylines, and magic system. It has no relation to the Axel Kingdom Hearts fanfiction.

Definitely Harry himself. His ability to adapt to new situations and his powerful magic would be really interesting in the Kingdom Hearts setting. Also, Sora. The clash or cooperation between Harry's magic and Sora's Keyblade skills would be cool to see. And Hermione, she could bring her intelligence and knowledge to analyze the new world they are in.

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.

A plot could involve Harry forming a band with his Hogwarts friends. They play guitar - based magic music that can break through dark magic barriers. As they perform around the wizarding world, they become famous not just for their music but also for their ability to use music as a form of magic. It would be a story full of adventure and friendship.

Well, the plot could be that Harry inherits an ocarina from an old wizard. As he starts to play it, he realizes it has the power to open hidden passages in Hogwarts. He then embarks on a journey to discover what these passages lead to, all while trying to keep his newfound ability a secret from the teachers and Malfoy and his gang.

One possible plot could be that Harry discovers airsoft during a visit to the Muggle world. He becomes fascinated by it and decides to introduce it to his wizard friends at Hogwarts. They then start having friendly airsoft battles in the Forbidden Forest, using magic to enhance the game in a safe way, like creating magical shields for protection.

In a more complex plot, Harry could be part of a prophecy that involves him using the power of music from the piano to defeat Voldemort. He has to learn special musical spells and collaborate with other musical - inclined wizards and witches. Along the way, he also has to face challenges from those who think music has no place in the wizarding world and wants to stop him from using the piano as a weapon against the dark forces.

The plot could be that Harry discovers an old cello in the Room of Requirement and starts to play it. His music attracts the attention of a long - lost magical being who then helps him in his fight against Voldemort.

Perhaps Voldemort discovers the power of the Heartless and tries to use them to his advantage. The protagonists from Kingdom Hearts then have to work with the Order of the Phoenix to stop Voldemort and the Heartless. The Hogwarts students could be fascinated by the Keyblades and the different worlds the Keyblade wielders have been to, and there could be a lot of cultural exchange between the two groups.
