What are some interesting crossovers in 'Harry Potter' and 'Final Fantasy XV' fanfiction?

A possible fanfic could explore the concept of the crystal in Final Fantasy XV and the Fayth in Final Fantasy X. Maybe the crystal's power has some sort of connection to the Fayth, and characters from both games have to figure out how to use this connection to restore balance. This could involve a journey across both worlds, with characters learning about each other's cultures and histories along the way.

One interesting crossover could be the use of magic systems. In Harry Potter, magic is more about spells and incantations, while in Final Fantasy 12 there are various magicks like black, white, and green magick. A fanfiction could explore a character from Harry Potter learning the magick system of Final Fantasy 12, perhaps Hermione trying to study the more scientific approach to magic in Final Fantasy 12.

One interesting crossover could be the use of magic spells from Harry Potter in the world of Final Fantasy 7. For example, a character might use 'Expelliarmus' to disarm a Shinra soldier. Another could be the appearance of Final Fantasy 7 creatures in Hogwarts. Imagine a Chocobo running around the Quidditch pitch! Or perhaps a character from Final Fantasy 7 attending Hogwarts and having to learn about magic while also using their own unique abilities.

A possible crossover aspect is the world - building. The post - apocalyptic world of 'owari no seraph' and the more fantastical world of 'Final Fantasy XV' could merge. Maybe the characters from 'Final Fantasy XV' end up in the world of 'owari no seraph' and have to deal with the vampire - human conflict. They could bring their own technology and magic, which would change the balance of power in the 'owari no seraph' world.

One interesting crossover could be the use of magic systems. In Harry Potter, magic is mainly done through wands and spells, while in Final Fantasy X, magic is more about summoning and using different elements. A fanfiction might combine these, like having a wizard in the Harry Potter world learn to summon aeons from Final Fantasy X.

Well, in some fanfictions, the characters' personalities might be combined. Cloud from Final Fantasy VII could be a student at Hogwarts with his brooding personality. He might be in Slytherin, using his skills with a sword (which could be magically enhanced) to protect the school. And Hermione could find herself interested in the technology of the Final Fantasy VII world, trying to figure out how the materia works and if it could be used in the wizarding world to enhance magic.

One idea could be exploring the backstories of the main characters in more depth. For example, Noctis' training as a prince and his relationship with his father before the events of the game. Another could be a fanfiction set in an alternate universe where the Astrals have different roles or relationships with the humans. Maybe a story where Noctis and his friends have to face a new, unexpected threat that wasn't in the original game.

One interesting concept could be a crossover of the magic systems. In Final Fantasy XV, there's the use of elemental magic and powerful spells. In Naruto, there's ninjutsu. A fanfiction might explore how a character from one universe adapts to the other's magic. For example, a Naruto character learning to use the warp - strike ability from Final Fantasy XV in a battle. Another concept could be the interaction of the different races. The elves in Final Fantasy XV and the various clans in Naruto could have some really unique interactions, like how the Uchiha clan's sharingan might react to the magic - using races in Final Fantasy XV.

Well, in 'Harry Potter', magic is mainly about spells and potions. Harry can cast spells like Expelliarmus. In 'Final Fantasy XV', Noctis has the power of the Crystal and can use his sword skills along with magic attacks. In fanfiction, sometimes they might make Harry's magic more combat - oriented like in 'Final Fantasy XV', or give Noctis some spells similar to those in 'Harry Potter'.

A cool crossover might involve the jutsu in Naruto being combined with the spells in Final Fantasy 14. Picture Sasuke using a spell like Blizzard III from Final Fantasy 14, but with his own Uchiha - style twist. Also, the ninja villages in Naruto could be compared to the city - states in Final Fantasy 14. The fanfiction could explore how the politics and power dynamics of both worlds interact when characters from each are forced to cooperate. Maybe the Hidden Leaf Village and Limsa Lominsa form an alliance to fight a common enemy that threatens both their existences.
