To make this short, this request forum is like my Sonic request forum.

Marceline no tenía idea de todo lo que su presencia desataría en el castillo, pero solía creer en un cambio y por fin estaba sucediendo.

(To be filled in later)

After the attack of GLOB, there has been a royal meeting with all the royals in the land of OOO. A figure with a white cloak tells them something that would change everyone's future. Finn get involved in this situation, and discovers something... different. Rated T for Language. don't own AT, nor the image shown. COMPLETED. I'll try later on a better version of this story.

Co-op story with me and TME. After the events of Fir and Ice, Finn decides to relearn magic and among other things. If you wish to find out more, then read along. Harem like always.

Finn is assigned to escort a human by the name of Nicholas Blackwater around the land of Ooo where he meets Princesses, a Vampire, and more on this strange but oddly exciting adventure.

When Princess Bubblegum heard of Jake's interactions with Prismo, she went to make her own wish. The aftermath was much more terrible than she had predicted.

(I have not written any of these!) In summary, these are random stories that people have either written on 4chan Adventure Time threads or somehow have sent to me to be shared anonymously. Since there is no common theme, I'll just be adjusting the tags to be what is in all the stories and have the chapter title explain what is in the chapter itself. There will be both NSFW and SF

A Co-Op Rewrite to my original story "Finn the Red" by TME and I.

This is a what if story of how the Silent King episode ended differently if Finn stayed King. Co-Op story by me and TME and is a actual B-Day gift. Features some of our go to OCs. No flames please.

After the death of Jake, life isn't the same for Finn Mertens, he feels empty and aimless. But a new journey awaits, and a Legend is needed.

Prismo has pulled Finn and Jake into his home (which is very different from last time they were there) for a strange quest. As they move on through this journey, they begin to question this quest.

"Oh, I'm evil alright." He got closer until she could feel his warm breath on the back of her neck from where he stood a foot taller than her. "I know all of these guys down here. Evil is in my core, and only beings like that can survive down there. Hero or not, you are still just a delicious human jumping off of a cliff into the belly of the beast." Set after "Tastes"

prismo discovered an alternative ooo where Finn and Phoebe lives are swap

His brother just didn't seem the type for markings - for painful flourishes rendered with ink and needles on naked skin – and it's bewildering how he managed to overlook something so obvious and extensive. AU.

After his break up with Flame Princess, Finn falls in love with Water Princess. But when evil threatens the Land of Ooo, fates will change, and Finn is caught between the two people he loves.

1000 years have past and the land of Ooo had not looked the same. Marceline then finds some clues that will help her go back to the past and stop any certain events. However she'll meet someone that reminds her of a certain human. Will have some slight Assassin's Creed moments, some yuri moments and a harem. Early birthday present from my friend TME (Twilight Master Emerald)

What if Bubblegum decided to make a study on many creatures of Ooo and hires many people to help her with the studies and many of them happen to not only go into details of said creatures lives... but their mating habits as well... look inside to find out more on BCS. (Lemon filled from start to finish.) (Ash Death in first chapter) (Male OC's will be used with female humanoids.)

In hindsight, living with someone you hate isn't so bad. Everyone says it will get better over time, so something good has to come out of this...right? Bubbline. College AU. T for language, drug and alcohol mentions. Rating may change.

Now that Golb was gone, it was time to rebuild. Rebuild not just all that got destroyed, but relationships too. Without a place to live after the treehouse got trashed, Finn and Jake will have to find a new place to live, and face new challenges that come along the way. Emotional challenges. Oh boy.

come on grab your friends, we'll protect this very distant land, with the princess of gum, and the soldier of grass, its adventure time. (first fanfic)

A brief look at a world where Martin Mertins ended up in the Citadel earlier than expected, and Finn returns to Ooo with a father that loves him dearly. (One-Shot unless people want more)

A bored and cynical teenager gets run over by a car, only to be reborn as a [Gamer] in the land of Ooo. Sounds easy right? Well, it should be except he attracts [monsters] from every direction in a way he can't control, simply because he's alive and monsters HATE people from other universes. Jared Fields is...the Gamer of Ooo. (SI/OC x Harem. Rated T for cursing.)

What if it wasn't Joshua or Margret who had found Finn that night? What if it was someone who sacrificed all she had to save the species before her? (One-shot)

[Oneshot fluff] Con Bonnie ya no había noches solitarias y un vacío en su vida; aún duelen las heridas del pasado pero Marceline ahora sabe que no tiene porqué luchar sola.
