I think Lincoln would be the most interesting. He's used to handling a big family and all kinds of chaos at home. In the Kingdom Hearts universe, he could use his adaptability and problem - solving skills. He'd be curious about the new worlds and the magic there, and his journey of discovery would be really engaging to read about as he teams up with Kingdom Hearts characters.
Luna from the Loud House could be a very interesting character to focus on. In a crossover, her love for music could have a unique connection to the magic in the Kingdom Hearts world. Maybe her music could have the power to calm the Heartless or even unlock certain hidden powers within the different worlds. Her rocker - girl attitude would also bring a different flavor to the usually more heroic and magical Kingdom Hearts cast.
Sora would be really interesting. His naivete and pure heart could be a great contrast to the dark and gritty world of Blade. He would probably approach the vampire - fighting situation with his usual optimism and might even try to find a way to redeem some of the vampires, thinking they are like the lost souls he has saved in the Kingdom Hearts worlds.
Naruto would be very interesting. His boisterous personality and his strong sense of justice would make for great interactions in the Kingdom Hearts universe. He could be constantly amazed by the different worlds and the magic in the Kingdom Hearts setting, and his growth as a character could be explored further as he faces new challenges outside of his own world.
I think Luna from the Loud House would be really interesting. She has that rocker vibe which could mesh well with the spooky and unique nature of the ghouls. And then there's Spectra Vondergeist from Ghoul School. She could use her ghostly abilities to have some cool interactions with the Loud kids. Maybe she could play pranks on them that are more friendly than scary as they get to know each other.
One cool plot idea could be the Loud family getting transported into the Kingdom Hearts universe. Lincoln could team up with Sora to fight the Heartless. Maybe the sisters would each have a unique role, like Luna using her music skills to soothe some of the more aggressive enemies. Another idea is that the Keyblade could choose one of the Loud siblings as its new wielder, leading to a whole adventure of them learning to use it and save both their world and the Kingdom Hearts worlds.
Well, it could be about the Loud family getting sucked into the Kingdom Hearts universe. Maybe Lincoln could be the main character who teams up with Sora. They'd go on adventures across different Disney - inspired worlds within the Kingdom Hearts setting, while also trying to find a way back home. Along the way, they might meet some of the Loud sisters who also got trapped and they all use their unique skills to fight off Heartless.
Sora would be a great choice. He's already a central character in the Kingdom Hearts series. In a Keyblade Wars fanfiction, seeing how he adapts to the chaos of the war, his moral compass in the face of such a large - scale conflict, and how his relationships with other Keyblade wielders change would be really interesting.
I think Lincoln Loud would be really interesting. He's used to dealing with a big family and all kinds of situations at home. In the Spyro world, he could use his problem - solving skills to help Spyro on his quests. His curiosity would also make him eager to explore the new world of Spyro.
I think Lincoln would be really interesting. He's used to dealing with a big family in The Loud House, so in Sword Art Online, he could use his leadership skills to form a guild with the other characters. His ability to adapt to different situations at home would come in handy in the dangerous world of SAO.
Sora and Elsa would be really interesting. Sora, with his positive and adventurous spirit, could help Elsa come out of her shell more. Elsa, with her powerful ice magic, could offer Sora a different kind of magic to understand and work with.
