This first-ever Adventure Time Halloween Special brings Finn and Jake into a creepy new dungeon adventure packed with tricks, treats, monsters, and the kind of weird, funny danger only the Land of Ooo can deliver.
Written by Jeremy Melloul, with art by Adam Seats, colors by Rebecca Nalty, and letters by Shawn Lee, this 48-page special looks like a perfect seasonal pickup for longtime Adventure Time fans, younger readers, collectors, and anyone looking for a fun Halloween comic that mixes spooky energy with big cartoon adventure.

Finn and Jake Enter a Monster-Sized Halloween Quest
Adventure Time: Halloween Special #1 begins with a classic Finn and Jake problem: they sign up for a quest from the Adventurer’s Guild without reading the fine print.
That is already a dangerous move in the Land of Ooo.
Before long, the duo finds themselves trapped inside a mysterious dungeon where things get very weird very quickly. This is not just a regular dungeon crawl. Finn and Jake begin turning into some of the monstrous inhabitants inside the dungeon, forcing them to deal with danger from the outside and the inside.
That setup is perfect for Adventure Time.
The series has always worked best when silly ideas become surprisingly strange, emotional, or dangerous. A Halloween dungeon where Finn and Jake start becoming monsters gives this special plenty of room for comedy, creature designs, spooky visuals, and character-driven chaos.
Those Who Fight Monsters
The special carries the subtitle Those Who Fight Monsters, and that phrase fits the story perfectly.
Finn and Jake are used to battling bizarre creatures, strange magic, and weird threats across the Land of Ooo. But this time, the monster problem is personal. When the heroes start turning into the creatures they are supposed to fight, the adventure becomes more than a normal Halloween battle.
That gives the one-shot a fun hook for new readers.
You do not need to know every corner of Adventure Time lore to enjoy this. The premise is easy to understand: Finn and Jake enter a dungeon, things go wrong, monsters appear, and the heroes may be turning into monsters themselves.
That is a strong Halloween comic setup.
Jeremy Melloul and Adam Seats Bring the Tricks and Treats
Writer Jeremy Melloul gives the special a story that sounds perfectly built for the franchise: funny, spooky, weird, and full of danger that probably comes with a lesson hiding somewhere underneath the chaos.
Artist Adam Seats brings the visual energy needed for a monster-heavy Adventure Time story. The covers already show exactly why this special should stand out on shelves. The monster designs feel playful instead of too scary, while Finn and Jake keep the book grounded in that familiar Adventure Time charm.
This is the kind of comic that can work for readers who want Halloween atmosphere without losing the fun, colorful spirit of the show.
A 48-Page Halloween One-Shot
At 48 pages, Adventure Time: Halloween Special #1 is a bigger release than a standard single issue.
That extra page count matters because Halloween specials should feel like events. This gives the creative team more room for dungeon exploration, monster transformations, weird jokes, and big spooky set pieces.
It also makes the issue feel like a strong seasonal pickup for comic shops. Fans looking for something Halloween-themed, kid-friendly, and collectible should have this one on their radar.
With a $7.99 price point and multiple covers, this looks positioned as a fun fall release for readers and collectors.
