What are some interesting ideas for naruto and trollhunters fanfiction?

You could also create an OC human who discovers a hidden talent for communicating with trolls through music. In the fanfiction, this character could use their musical ability to bridge the gap between the two worlds, maybe even creating a new form of harmony between trolls and humans that was previously unthinkable.

How about a crossover with the Percy Jackson series? The Trollhunter could meet Percy and his friends at Camp Half - Blood. Since both deal with mythical creatures, they could exchange knowledge about different mythologies and fight side by side against monsters that are drawn to the power of trolls and the demigods.

Jim could be hurt by a new type of dark magic that the trolls are using. This would force his friends to research and learn about this magic to find a cure. It could also introduce new characters who are experts in this kind of magic.

For 3 below trollhunters fanfiction, you could write a story where the characters get stranded on an unknown planet during one of their space travels. They have to use their skills and knowledge from both their home world and what they've learned on Earth to survive. Another plot could be that a new alien race arrives on Earth, and the 3 below characters have to decide whether to trust them or not, while also dealing with the trollhunters' reactions. And, a story about the characters trying to find a way to reverse the damage they've accidentally caused to the environment on Earth would also be great.

Another idea is a crossover with 'Avatar: The Last Airbender'. The Trollhunters could meet Aang and his friends. They could combine their powers to defeat a common enemy that has the ability to disrupt both the balance of the four elements and the Troll world's magic. For example, they could fight a dark spirit that is draining the magic from the Troll world and using it to spread chaos in the Avatar world.

One idea could be that the characters from Trollhunters and 3Below have to team up to fight a common enemy that is threatening both their worlds. Maybe an ancient evil that has the power to destroy Arcadia and Akaridion - 5. Another could be a story where the technology of 3Below is combined with the magic of Trollhunters to solve a mystery that has been plaguing both species for centuries. For example, a mystery about a long - lost artifact that has the power to reshape their universes.

Maybe the technology from '3 Below' gets mixed up with the magic in the Trollhunter universe. For example, Aja and Krel's advanced tech could malfunction in the Troll world and create some unexpected chaos. The Trollhunters would then have to help them fix it while also dealing with their own troll - related problems.

One interesting 'trollhunters fanfiction' story could be about an alternate universe where the trollhunters are from different time periods and have to team up.

There are also those that explore romantic relationships between the characters in a new and unique way.

One idea could be that the characters from 3 Below end up in Arcadia Oaks where the Trollhunters are. They could team up to fight a common enemy that threatens both their worlds. Maybe the Gumm - Gumm trolls somehow form an alliance with the bad guys from 3 Below's planet, and the combined forces of the heroes have to stop them.

One interesting storyline could be Merlin using his magic to help the Trollhunters in a battle against an ancient and powerful troll enemy. Maybe he could use his knowledge of spells to create a magical barrier that protects the trolls and humans working together. Another could be a time - travel plot where a Trollhunter is sent back in time and meets Merlin, and they have to work together to change something in the past to save the future of both the troll and human worlds.
