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.
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.
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.
In this crossover fanfiction, the Hulk's strength could be used to help the Loud family in a big way. For example, there could be a natural disaster about to hit Royal Woods, like a huge flood or an earthquake. The Hulk, with his superhuman strength, could hold back the floodwaters or stop the shaking ground. Meanwhile, the Loud kids could be helping the townspeople evacuate. It would be a story of how two different universes come together to save a town.
One idea could be that the Loud family somehow gets transported to Gotham City. Lincoln could befriend Robin and they team up to solve a mystery that involves both Gotham and Royal Woods' villains. Maybe the Joker has a plan that involves stealing a special item from Royal Woods, and the Louds have to work with Batman to stop him.
The plot could involve the Hulk being shrunk down to the size of the Loud House family. He would then have to live with them and adapt to their chaotic household. The Loud kids would be fascinated by his strength and the Hulk would learn about family values from the Louds. There could be comical scenes where the Hulk tries to fit in, like sitting on the tiny furniture or trying to eat normal - sized food.
To write a great Loud House x Batman crossover fanfiction, focus on the interactions. Let the differences between the two groups create interesting dialogue and situations. The Louds' humorous and family - centered dynamic can contrast with Batman's solitary and serious nature. Also, don't be afraid to introduce new elements or twists. Maybe there's a secret connection between one of the Louds and a character from Batman's universe that gets revealed during the story. And always proofread and edit your work to make sure it flows well.
One great 'Kingdom Hearts Crossover Fanfiction' is 'Kingdom Hearts and Final Fantasy: The Convergence'. It combines the elements of Kingdom Hearts and Final Fantasy in a really interesting way.

Sora and Cloud are quite popular. Sora's cheerful and determined personality combined with Cloud's brooding and powerful presence make for interesting interactions. They can be portrayed as allies, learning from each other's fighting styles, or even as rivals in some fanfictions.
