Perhaps a new character introduced in the Alola fanfiction could be Ash's love interest. This character could be a strong Pokémon trainer from a different part of Alola, with unique Pokémon and a different battling style. Ash would be drawn to her determination and skills, and as they train together and face challenges, love could develop.
It could be Lillie. She is kind - hearted and has a deep connection with Pokémon. She and Ash have had many adventures together in Alola already. Her gentle nature and her growth throughout the series could make her a great love interest for Ash.
Well, in some fanfictions, Ash might fall in love with a fellow Pokémon coordinator in Alola. They could start off as rivals, constantly trying to outdo each other in Pokémon showcases. But as they see the dedication and kindness in each other, their relationship changes. They might start training together, sharing tips on how to make their Pokémon look more beautiful and perform better. This mutual respect and admiration could easily turn into love. Or perhaps Ash meets a mysterious girl who has a special bond with a rare Pokémon. Ash is intrigued by this bond and wants to learn more about it. As he delves deeper, he falls for her.
One possibility could be a young girl who accidentally stumbles into his realm. She might be different from others, with a kind heart that catches Slender Man's attention. Maybe she's not afraid of him at first sight, which intrigues him.
One potential love interest could be a half - elf. They would bring a unique blend of both elven and human qualities, which might intrigue Thranduil. Or it could be a nature spirit. Since Thranduil has a strong connection to the forest, a nature spirit who embodies the essence of the forest could be a fascinating match for him. Also, a powerful sorceress from a far - off land might be his love interest, with her magic and mystery attracting him.
His love interest could be Wendy's sister. In some fanfictions, a sister of Wendy who was always a bit more curious about Neverland than Wendy herself could be the one Peter Pan falls for. She might be more daring and willing to fully embrace the wildness of Neverland, which attracts Peter.
A strong female Autobot would be a great love interest. They already share the same values and goals, and the bond of being on the same side in the fight against the Decepticons could easily turn into a deeper emotional connection.
A strong possibility could be Misty. They've been traveling companions for a long time. Misty has shown care and concern for Ash over the years, and there have been moments that could be seen as the start of a deeper connection.
A mortal could also be a good love interest. Imagine Nico, who has been so involved in the world of gods and demigods, falling for a normal human. This mortal could be an artist or a scientist, someone who sees the world in a completely different way than Nico. Their relationship could be about Nico learning about the mortal world through this person's eyes and falling in love with both the person and the new perspective.
Another possibility is Kyosuke. In the original story, Madoka had some feelings for him. In this fanfiction, they could explore a deeper romantic connection, perhaps with some twists and turns that are different from the original plot.
There's also a possibility that it's a healer in his village. She might have been the one to patch him up after battles. Over time, she gets to know the real Deidara behind the tough ninja exterior. Her gentle nature could contrast with his more brash and explosive personality, and this contrast could be what draws them together in a love story.
It could be a kind - hearted Who girl. She might be the one who is always helping others and she sees the good in the Grinch even when no one else does.
