Some dedicated fan communities or forums might also be a good source. For example, there could be a sub - reddit specifically for fans of the Trollhunters franchise. Here, fans might share their own fanfictions or recommend ones they've read. You just need to be an active part of the community to discover these hidden gems.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms have a large collection of fanfictions related to various shows, including 3 Below Trollhunters of Arcadia. Just use the search bar and type in relevant keywords like '3 Below Trollhunters of Arcadia' to narrow down the results.
One great theme is friendship. The characters in the show have strong bonds, and fanfictions often explore how these friendships develop further or face challenges. For example, a fanfic might focus on how the main characters support each other during a difficult mission.
The ones living beneath the fictional town of Arcadia in Trollhunters are mainly a diverse group of trolls. They have their unique habitats and way of life, which adds to the intrigue of the story.
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.
In a Jim x Morgana fanfiction, it could start with Morgana being trapped in a magical prison created by the Trollhunters long ago. Jim, out of his sense of justice and curiosity, decides to visit her. As he gets closer, he realizes that Morgana has a complex past and motives that are not entirely evil. Their interactions could then develop into a strange friendship that the other Trollhunters might not understand.
If you're looking for a place to engage with Trollhunters fanfiction, Fanfiction.net could also be an option. It has been around for a long time and has a decent amount of Trollhunters - related stories. Just be aware that the interface might not be as modern as AO3, but it still has a lot to offer in terms of content.

You can search for 'top Trollhunters fanfiction on YouTube' and look at the videos with the most views and positive ratings.
You can try Archive of Our Own (AO3). It has a large collection of fanfictions, including those for Trollhunters. The tagging system there makes it easy to find exactly what you're interested in.
One possible fanfiction could be where Jim gets seriously hurt during a battle with a powerful troll. His friends then have to find a way to heal him, perhaps by seeking out a rare magical herb that is said to have great restorative powers. This could lead to a journey filled with various challenges and character development for his friends as they race against time to save Jim.
One great Steve x Eli fanfiction is 'The Unlikely Bond'. It beautifully explores their friendship evolving into something more. The author does a wonderful job of staying true to the characters' personalities from the show. Another one is 'Shared Secrets' which delves deep into their shared experiences and how it brings them closer. It has some really heart - warming scenes.
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.
