What if Fern got what he wanted that day? He successfully killed Finn the Human and was now attempting to live his life as he always should have… but, now what? All the while, a certain uncle takes matters into his own hands and creates something… interesting.

Had this on AO3 and might as well put it here. Something something Marceline prank, something something gone wrong. News flash Finn became a vampire and is now going on a carnage spree. Will he regain his sanity before it’s too late? Or will he be a rabid animal until he dies? Idk I’m writing this as I go so let’s find out.

In a world where humans were considered the worst of monsters, a child who just so happened to be one strives to become a kind of monster that protects the people who can’t protect themselves.

Olvidaste tus Flotadores pero encallaste en una isla.

Finn Martin has been trying to find his brother since he went missing. His search lands him in trouble with the law, where he’s given a choice. Become a test subject for a secret government agency, or go to jail. This one choice leads to a whole new world, and a whole new life for the young man. Superhero AU.

This story takes place in an alternate timeline where Martin leaves his son behind as he escapes the Isles. Rather than going on fantastic adventures every day with his magical dog, Finn is raised to be a Helper within human society. Finn becomes a Campbell. This story is darker than the main series of events. Be prepared for a slow burn as Finn descends into madness.

Finn and Fern have grown up in a world full of magic and fantasy, and both of them aspire to be heroes that help others. The both of them are still kids though, and all they really do is adventure to find some fun with their friend Jake, but with a place like Ooo, many things can happen. Can they take it on? Or will they be blown away like dust off the wall?
