For Douxie, being an immortal wizard had a lot of perks, but also a lot of downsides. One being that he forever looked 16. One day he gets caught by the police and sent to live with a foster family, the Lakes, and gets far more attached to them than he'd planned. But apparently living with the Lakes came with it's own downsides, and his life gets turned into chaos. But it's all worth it for family, right? Basically Douxie gets sent to live with Jim and Barbara, but of course since Jim is the Trollhunter shit just keeps happening and Douxie wants nothing more than to keep his new family safe. In this Jim has been the Trollhunter for a couple months and of course it's very canondivergent because Douxie is now part of the equation. Canon ships only cos It's one of the only shows where the canon ships are actualy really good and cute. Also I know I used the cover art for another one of my fics but I literally cannot find any other art or anything with Jim and Douxie in it so sorry but this is my go to. Sorta inspired by this fic on AO3 called Pros and Cons of Eternal Youth by claycastles, but not a bunch. Enjoy!
