Who could be the potential characters in a Kingdom Hearts harem fanfiction?

A character from a world of music could be a great addition. They could use musical notes as attacks or defenses. For instance, they could play a melody that heals allies or a discordant tune that stuns enemies. And a character who is a time - traveler from a world where time is in chaos. They could have the ability to freeze or speed up time in certain areas, which would add a whole new dimension to the battles and adventures in the fanfiction.

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.

There could be some original Arrancar characters created specifically for the fanfiction. For example, a young and curious Arrancar who is new to the ways of her kind. She meets Naruto and is immediately fascinated by his different appearance and abilities. And then there's a more experienced Arrancar who has seen many battles. She initially sees Naruto as a threat but then realizes his good intentions and slowly falls for him, becoming part of the harem.

Riku could also play a major role. His more complex and sometimes brooding personality could add an interesting dynamic. He might start off as a bit of an outsider in Equestria but eventually come to understand and care for the ponies, especially if there are some ponies who remind him of his friends from his own world.

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.

Rukia could be one of the characters. Since she has a deep connection with Ichigo already in the original series, it would be easy to develop a more romantic aspect in the harem setting. Orihime is also a likely candidate, as she has strong feelings for Ichigo. And from other animes, a character like Saber from 'Fate/stay night' could be interesting. Her noble and powerful nature would contrast with Ichigo's more rough - around - the - edges personality.

Well, obviously Oliver Queen from the Arrowverse could be the central male character. For the female characters, Felicity Smoak could be one from his own universe. Then from other multiverse versions, there could be a more ruthless version of Black Canary or a super - powered version of Laurel Lance. They could all interact with Oliver in different ways due to their different personalities and abilities from their respective universes.

Well, obviously Lucy from Fairy Tail would be a likely candidate. She already has a strong connection with Natsu in the original series. Then from the world of Bleach, Rukia could be an interesting addition. Her cool and collected nature would contrast with Natsu's hot - headedness, and her Soul Reaper powers would add an interesting dynamic to the harem. Also, from Attack on Titan, Mikasa could be in the harem. Her strong combat skills and protective nature towards Eren could translate into a similar protectiveness towards Natsu in the fanfiction.

Gwen could be one of the characters in the harem. She already has a close relationship with Ben in the original series. Another could be Kai Green. She's shown interest in Ben before and could easily be part of a harem in a fanfiction. Also, female aliens like Rook's sister (if she exists in the fanfic's version) could be part of it.

In a crossover with Sailor Moon, Sailor Venus could be part of the harem. She is a strong fighter like Goku in her own way, and their different powers and personalities could create interesting dynamics.
