- Comments: Besides The Citadel Of Truth mentioned below, his fan fictions centers around the Flinn (Finn/Flame Princess) pairing each with different genres and set in different universe.
General Fics
Stories focused on the family and the friendly relationships of the cast. Plot-focused stories or light day-in-the-life stories. Pretty much anything that isn't focused on romance.
- Recommended by CMR Rosa
- Status: Complete
- Synopsis: Flame Prince sets out to burn Fionna's treehouse to the ground after being rejected. What happens when she finds him caught in the rain and takes him back to her treehouse?
- Pairing: Flame Prince and Fionna
Add ReviewMy Brothers by Sailor Water Dragon

- Synopsis: Fionna finally decides to have her boyfriend meet Gumball and Marshall. Unfortunately they already know each other, and still holding grudges.

The Stasis Project by Cyrus Campbell
- Recommended by hisaishi
- Status: Dead Fic
- Synopsis: "Finn has always wondered about his existence. When the past reveals his identity, he must make a choice. Stay with the ones he loves or the ones he wants to love. All the while, one man's imagination tugs at the strings, creating clouds of discord."
- Pairing: None so far.
- Comments: The story is yet to be fully realized but its first chapters have gained well written reviews. The humor sounds like the actual show and doesn't try to force anything on the reader. One user, Ruby Sword (writer of the above The Last Human), points out a Homestuck-style of humor. In addition, there are decent references, including Regular Show and The Elder Scrolls IV: Oblivion. While one user says it's a crossover due to Mordecai and Rigby's appearance, the author has made known that it is mainly Adventure Time and thus, an Adventure Time fanfic. The only complaint is update time. Months could go by before another chapter resurfaces. In addition, the plot has yet to be fully realized. Overall, the style is nice and the plot shows promise.
Through The Wreckage by Hephestus
- Recommended By bigflatwhat
- Status: Dead Fic
- Synopsis: "A revelation regarding the fate of one of her closest friends drives Marceline to delve into her own past. Revisiting old scars and uncovering truths about her friends, her family, her world, and most importantly herself."
- Pairing: None
- Comments: Those of you familiar with the MLP/Doctor Who crossovers Time Lords and Terror and Mines of Dragon Mountain will be pleased to know that Hephestus is once again writing, albeit not for the same fandom. The story takes place directly after the episode 'I Remember You' and utilizes Marceline telling Finn and Jake about her history with the Ice King as a framing device for the main narrative. The main narrative so far has focused on Marceline as a child during the mushroom war and effectively portrays how awful such a scenario must have been. Although quite new, the writing is rich and effective and the characterizations are great. This is definitely a fic to keep an eye on.

- Status: Complete
- Synopsis: Basically how The Lich thinks and feels. Makes him somewhat more understandable (yet alien), and depending on who you ask even outright bitter, but his reasoning is still quite chilling and inhumane, as he should be.
Marceline's Adventures in a Wasteland by gveret
- Recommended by rapraccoon
- Status: Complete
- Synopsis: After the Mushroom War, the world was mostly magic. But it wasn't all sweet and shiny just yet.
- Comments: Somewhat older and somewhat Jossed three-shot about a young Marceline surviving and adventuring in a post-apocalyptic, pre-Ooo world. Sometimes sad, sometimes sweet and frequently charming.
Not Going Anywhere by kokadee
- Recommended by Tetronix
- Status: Complete
- Synopsis: Marshall Lee decides to pay a visit on Finn.
- Pairing: Finn and Marshall Lee
- Comments: This one-shot is both heartbreakingly sad and adorable at the same time. I personally don't like the Finn/Marshall pairing, but the author manages to pull it off.
- Recommended by dwarfstar
- Status: Complete
- Synopsis: Princess Bubblegum makes some discoveries about her relationship with her vampire bud on one of their midnight excursions.
- Pairing: Princess Bubblegum and Marceline
- Comments: A heartwarming exploration of Marceline and PB's attraction towards each other, complete with cute science references that are oh so typical for PB. The writing style is also elegant, wordly and detailed, but very far from Purple Prose.
- Recommended by priopraxis
- Status: Complete
- Synopsis Finn and Jake stumble upon a thousand year old side-quest.
- Comments Short, atmospheric, well written and quite melancholy.

- Recommended by rapraccoon

Crimson Temptation by PretendPlay
- Recommended by: Sean Devine
- Status: Complete
- Synopsis "Finn? What happened to you? Are you okay?" Jake looked scared and he had every reason to be. Finn knew he was pretty torn up, but he hesitated on telling his best friend how he got so injured. He just didn't want Jake to get the wrong idea. Marceline… Marceline hadn't meant it. It was an accident.
- Comments Don't let the title fool you, this is not a shipping fic. This fic deals with the potential dangers that come with being a vampires friend.
- Recommended by: Sean Devine
- Status: Complete
- Synopsis "I swear Finn, you're never gonna grow up." Jake would laugh, and then dog-pile Finn to give him a wet-willie. And as Finn catches Jake in a headlock, he replies the same way he always does. "Growin' up is for suckers!"
- Comments: In which we see Finn's life from beginning to end, at both times sad and heartwarming.

Her Loyal Friend by BlueNinja0324
- Recommended by: Loekman 3
- Status: Oneshot
- Sypnosis: When Flame Princess comes to Finn for help, the human must put aside all his feelings in order to help her reclaim her throne.
- Comments: A Fix Fic of "The Red Throne" that rerails Finn from a love-maniac who would flirt with her ex at every opportunity to annoying levels into a hero who would do anything to help his girl, even if he must put aside his feelings for her. While the ending is quite predictable, if you disliked Finn's behaviour in "The Red Throne" and prefer him to act like the true hero he is, then this fan fiction is just for you.

- Synopsis: A young Martin washes up on the Land of Ooo about sixteen years in the future. He becomes overwhelmed with all the mutations he sees, but even then, nothing is more shocking than the news that his son is on the island. It turns out, there's a lot of explaining to do.

Shipping Fics
Stories focused on the romantic relationships between the cast.
Finn and Marceline by Planet Cool
- Recommended by Carth
- Status: Dead Fic
- Synopsis: Jake experiences jealousy and loneliness after Finn starts spending more time with Marceline.
- Pairing: Finn and Marceline friendship. So far, anyway.
- Comments: That synopsis is woefully inadequate, but an attempt to explain what this story's about and where it goes would result in my copying the fic word-for-word. If this isn't the best AT fic out there, it's at least the best gen fic. Has the zany feel, snappy dialogue, and subtle bawdiness of the best Adventure Time episodes, not to mention brilliant characterization and action packed action sequences of action. The perfect cure for the end of the season.
The Last Human By: Incognito Joe
- Recommended by Deep C, Xalts, Lord Ed
- Status: Complete
- Synopsis: "Following Princess Bubblegum's unexpected marriage to a stranger, a seventeen year old Finn decides to move on from his heartbreak by trying to discover the truth about his heritage, and if he is, in fact, the last of his kind. Finn's POV".
- Pairing: Finn and Marceline.
- Comments: This fanfic is quite well written. The dialogue sounds just like it was taken from the series, the new characters are quite interesting and are not too OP. Finn's first person perspective is handled quite well, along with the love triangle between Finn, Princess Bubblegum, and Marceline. At this rate, this fanfiction deserves its own Tropes Article. - Deep C
- Seconded. The Adventure Time section of FF.net can be a painful trawl but finding gems like this makes it all worth it. Absolutely brilliant - Xalts
- Also seconded. It's a superb story, the characters are spot-on and the fic itself is extremely well written. I enjoyed the drama and the dialogue was great. If I hadn't known better, I would think I was reading the long-lost script to a scrapped AT finale. Simply beautiful. - Lord Ed
Fast As You Can By: Incognito Joe
- Recommended by: Sean Devine
- Status: Complete
- Synopsis: Still battling her evil nature, Marceline runs away from her life with Finn, and has to decide what it is she really wants. Oneshot follow-up story to The Last Human.

The Elder God of Chaos by Neverthrive
- Recommended by Deep C
- Status: Complete
- Synopsis: "A character from Marceline's past is coming to destroy the land of Ooo and Finn must stop it, no matter the cost. Marceline X Finn. For the Tree Stumps contest".
- Pairing: Finn and Marceline.
- Comments: This is actually a pretty good fanfic. While there are some spelling errors, the flow of this story is well done. The OC known as the Elder God of Chaos is pulled off quite nicely and is anything but a bland powerhouse. The part with Billy telling Finn that there is no other way to save Ooo but to sacrifice himself is fairly heart-breaking. I would recommend this fanfic for certain. Plus, the ending with Finn becoming a vampire actually caught me by surprise.
Second Chances by Neverthrive
- Recommended by Deep C
- Status: Complete
- Synopsis: "Finn has adjusted to his new un-life with Marceline, but now a mysterious new group prepares to resurrect an old foe, threatening to devastate Ooo once more".
- Pairing: Finn and Marceline.
- Comments: Direct sequel to "The Elder God of Chaos". Once again, this is a pretty well done fanfic and everyone manages to stay in character. The action scenes and the dialogue between Finn and Marceline are fairly amusing.
The Human Condition by Finnthe Manly Human

- Synopsis: As Finn comes to terms with being single again, a chance event leads him face-first into Fionna, and his life in Ooo is forever changed. (AU Finn/FP breakup)

Dark Fiction

Be My Escape by The Master Hama
- Recommended by Jinxed Minx
- Status: Complete
- Synopsis: "It was like it needed to rip her apart to get out and then tear him to shreds, too. If you could feel that kind of yearning, you would've taken the chance already."
- Pairing: Finn and Marceline.
- Comments: In this fic, The Master Hama shows the dire consequences of being the last human in Ooo. Very well written, and Marceline's and Finn's slightly twisted relationship is both Heartbreaking and Heartwarming. Definitely worth a read.
Be My Escape: What Was by Dark Wrath 20
- Recommended by: Sean Devine
- Status: Complete
- Synopsis: This is not an alternative story. Its more of a add-on to The Masterhama's story.
Addiction by Low Candela
- Recommended by: Sean Devine
- Status: Complete
- Synopsis: Slumped in a steep depression, Finn finds a coping mechanism in a close friend of his; even if he isn't fully aware of the situation... Fair warning, rated M for a significant reason.
- Pairing: Finn and Marceline.
- Recommended by: BNSF 1995
- Status: Dormant
- Synopsis: Disillusioned and confused about his place in the world. Finn is offered the chance to start over in a new place with those who were long thought to be all but extinct. Will this new home be permanent for him and can he really forget about OOO.
- Pairing: Finn/Flame Princess
- Comments: Wow. Just...wow. This is one of the greatest AT fanfics I have ever read. Not only that, it's one of the best fanfics overall I have ever read. The character development is well-done and believable, the story has heart, humor, and richness, and the Big Bad Lucian reminds me greatly of Lelouch. The The Dragon and Starscream Connor is also a delightfully deranged character who definitely crosses the Moral Event Horizon when...you'll have to read for yourself.
Alternate Universe Fics
Stories where one fundamental aspect of the series is completely overhauled from its point of origin.
Tales of the Alternate Universe by 00SparkAchu00
- Recommended by: Sean Devine

- Synopsis Finn Mertens lives for the sake of his family. He always tries his best to be a good boy and help his father bring some bread home. However, his life won't be as easy as it seems.

Pray For The Preacher's Daughter by Arca Feretory
- Recommended by: powerespect
- Status: Complete
- Synopsis: "I can be a saint if you want me to, but I will make a sinner out of you. I'm innocent outside, but I'm about to blow your mind. I'm a little good, a little bad, the best and worst you've ever had. You can see my halo or my horns, so be warned." - AU, high school. Also, a warning: This is quite possibly the slowest burning story you will ever read.
- Pairing: Marceline/Bubblegum
- Comments: High school AU where Bonnibel moves to a small church town and begins tutoring the preacher's daughter, Marceline. The fic moves VERY slow, but the buildup is well worth the wait.
A Life to Serve by Low Candela
- Recommended by: Sean Devine
- Status: Complete
- Synopsis: An AU work. Marceline buys Finn as a slave at a young age, not completely sure of her motivation. How will Finn's twisted psyche develop as Marceline molds him into her perfect servant? Rated M for suggestive themes (possible lemon later), and likely violence.
- Pairing: Finn and Marceline.
- Recommended by: Mc 123
- Status: Ongoing
- Synopsis: Simon gets the power of the crown, but he doesn't lose his sanity or Betty. The war happens and Simon and Betty find Marceline and raise her as their own. The new family face many difficult challenges. There will be love, laughs, and tears. A story in which a hero will rise and help defeat a great evil in the distant future. A different Ooo will rise and take shape.
- Pairing: Simon/Betty
- Comments:
- The story's fine. However, this troper found the numerous writing errors to get in the way of his enjoyment. If you can overlook some grammar and spelling mistakes you'll enjoy it though. - Sean Devine
Phlogiston Theory by Jen Kollic
- Recommended by The Aussie Blue
- Status: Dead Fic
- Synopsis: "Find some way to contain her power, or I will." Famous last words for Princess Bubblegum. She should have known that Flame King would just take that as an open invitation to foist his responsibilities off onto her shoulders.
- Comments
- A change on the typical "X raised by Y" plot line, a well written, charming, and all together lovey story. Chapters can be short, and it's been a long time since an update.
Adventure Time by katkat-tan
- Recommended by Griffonmender
- status: Dormant
- Synopsis: This fancomic is a fun slice-of-life story set in modern day times featuring Fionna as the MC, with Pen and Finn as her older and younger brothers respectively. Has a manga-like art style and features anthropomorphic designs of many character. There's also a number of fun extras, like the ask pages.
- Comments: The best AT comic on Deviantart I've found. The art is amazing.
- Oh, but do be sure to read the description on the first page so you know the characters relative ages, as they differ from canon. Also note that Pen was the name of the boy character in the original Adventure Time short, so that you don't end up wondering who he is. Be patient, though: updates are slow.
The Fifth Element by ConnerWithARailgun''
- Recommended by Hurricane Fighter
- status: On Hiatus
- Synopsis: For centuries, four kingdoms have been locked in eternal war. The Kingdoms of Fire, Ice, Slime and Candy are all positioned to attack, no side able to break the stalemate. However, when the Ice Kingdom finds a frozen human in the ice, the Candy Kingdom prepares to counterattack... The Amnesiac Finn and the Ice King now must join forces and tip the balance of world power, or die.
- Comments: A very in-depth story, with a fun change of pace for almost all the characters involved. All of the characters are different, but not in a way that is completely unbelievable.
