A crossover with 'My Hero Academia' would be exciting. The kids could enter the world of heroes and villains. They might learn about quirks and how to use them to their advantage in their fight for survival. Maybe some of them would develop quirks themselves. Also, a crossover with 'Death Note' could be interesting. What if the smart kids from The Promised Neverland got hold of the Death Note? How would they use it to outwit the demons and escape their fate?
Imagine a crossover with 'Sword Art Online'. The virtual reality world of SAO has its own set of rules and dangers. The children would have to adapt quickly. They could use their strategic thinking to clear levels and find a way out. Or a crossover with 'Naruto'. The ninja skills and chakra system could be something the kids could learn and use to fight against the threats in their own world. For example, they could use ninjutsu to create illusions to deceive the demons.
One idea could be a crossover with 'Attack on Titan'. The children from The Promised Neverland could find themselves in the world of Titans. They'd use their intelligence and survival skills to figure out how to deal with the Titans, perhaps even finding a way to communicate with the abnormal Titans. Another plot could be a crossover with 'Fullmetal Alchemist'. The alchemical knowledge in that world might offer new solutions to the problems in The Promised Neverland, like finding a way to create a safe haven using alchemy.
One idea could be exploring what would happen if the kids found a secret passage in the orphanage that led to a different world, one not controlled by demons. Another could be a story where Emma and Ray make an alliance with a friendly demon who helps them rescue all the children at once. Maybe a fanfiction where they discover a way to reverse the demon's need for human flesh through some ancient magic.
One idea could be a pet that has special abilities which help the kids in their escape plans. For example, a pet bird that can scout areas without being noticed and report back to the children.
You could write a fanfiction where the children, after escaping, decide to go back to the orphanage to rescue the younger kids who are still there. This would involve them facing new challenges and enemies. They might also have to deal with their own traumas from the first escape while trying to save the others.
One interesting 'the promised neverland crossover fanfiction' could be a crossover with 'Attack on Titan'. It might explore how the kids from 'the promised neverland' would handle the Titans and the post - apocalyptic world of 'Attack on Titan'. They could use their intelligence and survival skills in a whole new and extremely dangerous environment.
Well, you could write a fanfic about the kids getting lost in a different part of the demon world during their escape. They would have to face new and strange types of demons and find their way back to the path of escape. Or, you could do a time - skip fanfic where the kids have grown up and are now trying to protect other children from the same fate they escaped from.
The theme of family or found family also persists. In a crossover with 'Fairy Tail', the guild in 'Fairy Tail' is like a big family. The kids from 'the promised neverland' could be integrated into this family - like environment. They would experience the warmth and support of a proper family while still having to deal with the threats from their original world or new threats in the 'Fairy Tail' world. This theme of family gives an emotional depth to the crossovers.
In a crossover with 'One Piece', Luffy would be an interesting addition. His carefree yet determined nature could inspire the kids from The Promised Neverland. He could also use his rubber powers to help them in their escape or fight against the demons. Another great character would be Light Yagami from 'Death Note' if we consider a different kind of crossover. His intelligence and strategic thinking could be a huge asset to the kids, though his morally ambiguous actions would also add an interesting dynamic.
