Where Can I Find Fanfiction Adventure Time With Original Character Quests?

My method is pretty simple: I stick to Archive of Our Own and use the ‘Filter’ function religiously. Go to the 'Adventure Time' fandom tag, exclude the major relationship tags you’re not interested in, and include ‘Original Character(s)’ plus ‘Adventure’ in the additional tags field. It cuts out most of the ship-focused stuff. You won’t get a ton, but what’s left is usually pretty solid. I found a great one last month about a human who falls into Ooo and has to bargain with Prismo; it had that classic quest structure. The search is half the battle, but AO3’s system is your best friend for it.

If you’re after original character quests in the 'Adventure Time' universe, I’d argue the real bread and butter isn’t on the major fanfiction hubs. Sites like AO3 and FanFiction.net have them, sure, but they tend to be swamped with ship fics and canon rehashes. The more dedicated OC quest narratives, the kind that really build out Ooo as a living world for a new hero, often migrate to forum-based roleplay communities or specific Discord servers. I stumbled on a whole ‘Land of Ooo Quest’ thread on SpaceBattles once, where the OP basically ran a collaborative story where readers voted on the OC’s actions – it was messy but wonderfully creative. The format lent itself to that exploration vibe way more than a static story chapter.

You might have better luck searching with tags like ‘OC-Centric’, ‘Quest’, or ‘Adventure’ on AO3, but honestly, the tagging system there can be hit or miss for this niche. Sometimes writers just don’t tag properly for OCs. I’ve had more success just searching the ‘Adventure Time’ fandom and then manually sifting through summaries, looking for keywords like ‘new hero’, ‘wandering’, or ‘exploration’. It’s a bit of a grind, but you occasionally find a writer who’s genuinely building their own corner of the world. I remember one fic where an OC was a former Candy Kingdom scientist trying to map the unseen parts of the Grasslands; it was all about discovery, not romance. That’s the stuff I live for.

Don’t completely discount Wattpad either, even if the quality varies wildly. The algorithm there can sometimes surface really obscure, passion-project OC adventures that haven’t gained traction elsewhere. Just brace yourself for a lot of self-inserts and rougher prose. At the end of the day, finding good OC quest fic feels less like browsing a library and more like treasure hunting in a weird, wonderful digital flea market.
