Who could be the main characters in a Kingdom Hearts and MLP crossover fanfiction?

The Keyblade wielders like Sora, Riku, and Kairi would bring a sense of adventure and a different kind of magic to Equestria. The ponies, on the other hand, could teach them about the power of friendship in a more direct way. Donald and Goofy might be a bit startled by the ponies at first but would soon get used to them. Donald's magic could be compared to the magic of some of the unicorn ponies, and they could exchange magical knowledge.

Aqua would be a really interesting crossover character with Roxas. Aqua has her own strong powers and a complex backstory. When she meets Roxas, she could see something in him that reminds her of Ventus. This could lead to a relationship where she tries to help him while also learning more about herself. Also, Riku would be a good fit. Riku has had his own journey of redemption and self - discovery. His experience could be useful for Roxas in a crossover situation, and they could have some intense battles together against the forces of darkness.

It could also be a new character created specifically for the fanfiction. This character could be from the world of the crossover and have some special ability or knowledge that helps in the fight against the Heartless. Maybe they have a deep understanding of the magic or technology in their world that can be used to counter the Heartless threat.

Sora would definitely be a main character. He's the protagonist in the Kingdom Hearts series, so it makes sense for him to be involved. The dalmatians themselves, especially Pongo and Perdita, could also be main characters. They could lead Sora through their world and help him understand their unique situation.

A new character could be introduced as the main character. This character could be a native of the kung fu - inspired world in the crossover. They could be the one to teach Sora and his friends about kung fu, and then join them on their journey to fight against the darkness that threatens both worlds.

One interesting plot could be that the ponies from MLP accidentally find themselves in the Kingdom Hearts universe. They might mistake the Heartless for some kind of dark magic creatures from their own world and try to fight them using their magic. For example, Twilight Sparkle could use her powerful spells to combat the Heartless while trying to figure out how to get back to Equestria.

One idea could be that Sora and his friends end up in Equestria. They could team up with the ponies to fight a new threat that is affecting both their worlds. Maybe the Heartless are somehow being drawn to Equestria's magic and they need to find a way to stop it together.

Godzilla himself would obviously be a main character. His actions and reactions would drive much of the story. Another possible main character could be Pinkie Pie. Her unique view of the world and her ability to make friends with anyone could play a role in how the ponies deal with Godzilla. Maybe she throws a party for Godzilla to make him feel welcome.

Link and Twilight Sparkle would be obvious main characters. Link with his skills in combat and exploration, and Twilight Sparkle with her powerful magic and intelligence. They could form an unlikely duo to face challenges.

For a main character from the human side, it's Michael Rosen. And from MLP, I think Rarity could be a main character. Rarity would be fascinated by Michael Rosen's different style of dress (compared to ponies) and might try to create pony - versions of his outfits. And Applejack could also be a main character, showing Michael Rosen how to work on the farm and sharing her values of hard work and honesty with him.
