A strange but intelligent titan lives deep within the forests of Wall Maria, right under the military's nose. What happens when the mysterious titan comes across two small children and the Scouts? Titan!Eren AU
Humanity's Strongest Woman
In every Kingdom, there is an epic era that defies the boundaries of time and immortalized itself in the history books. For mankind, an epic era they will never forget has finally emerged. The war between humanity and Titans has finally come to a head. Love cease to exist in a time like this, but they found it, and promised that it'll be worth it. Every stubborn inch of it.
Levi declares a one-man war on the sorry state of the military's pants (because whoever decided white was a good color for them was clearly an imbecile). Erwin is worried.
The hunter is a monster, a titan, not a boy. This is a fact he has known for as long as he has lived in the forest, for as long he can remember. The forest is quiet but for the crooning of birds, the rush of misty water into the hidden valleys and the deep lumbering steps of his kin. That is until the day that changes everything. The day the humans came. The day he saw his human.
Children Are Problematic
Things get complicated with Rivaille's [Levi's] squad once Eren magically turns into a child.
Can Titans Laugh?
by Song of the Black Wolf
Yet another meeting of sorts. Members of the royal council come to see a demonstration of Eren's titan abilities. Eren and Levi get bored, and the whole debacle inevitably ends in complete disaster.
Tower of Babel
After her previous college roommates moved out, Sasha managed to find the three replacements to keep her flat: Ymir, her alcohol connoisseur co-worker, Annie, a secret underground fighter, and Krista, the bastard of a rich man who pays her to keep her identity a secret. Three's all she needed, but when Sasha meets a homeless, pregnant teen by the name of Mikasa, she can't turn her away.
City Comma State
Inside the walls of his carefully maintained house, Levi has lived in peace, succeeding in leading the private life he's always wanted. This all changes when Hange moves next door and unknowingly infiltrates his life. That day he received a grim reminder...that he was capable of making friends.
It was supposed to be stupid fluff about a teddy bear. It turned into heartbreaking homeless 11-year-olds huddling for warmth.
Laugh All You Want
by ruined pride
Dying and being reborn was unlikely. Reincarnating into an anime? Highly impossible. But what took the cake was the fact that a human body wasn't always guaranteed in another life. Whatever entity that did this must be laughing its butt off now.
The Liquid Engineers
TF-1505 is one of the largest Titans ever captured by the Trost Testing Facility. Armin just happens to be the fifteenth researcher assigned to observe him.
Texts From the Survey Corps
Hanji decides to upgrade the Survey Corps by giving them cellphones and allowing them to text each other for better communication. Great idea, right? Maybe not, Hanji...
The Broken Doll
by Arcadian Nights
When Mikasa Ackerman is kiddnapped, she is not saved by Eren Jaeger. Instead, a thug from Wall Sina named Levi takes her under his wing. AU.
Speak Not of the Blackbirds
One mission gone wrong leads to an ancient forest, a mysterious town, and a race to safely return to the Walls called home with the odds against them.
All bets are off: they work together, or die.
This Feeling I'll Forget
Levi suffers from short term memory loss, and while that makes it hard for him to find love, he finds Erwin.
Miscommunication Is Key
Everyone seems to think Mikasa and Annie are dating. Mikasa is pretty sure they don't even talk, but hey. What does she know?
Single Daddies and Their Ugly Titan Children
Levi is a single father of two rowdy children. His neighbor, Erwin Smith is the widowed father of one. Due to their unique circumstances, the two families start spending time together and relying on each other in a sort of odd happy family.
Jean and Eren aren't exactly criminals, although there's a handful of IT and Business Affairs detectives scattered around the Upper Midwest who might take issue with the statement. They've just got...certain skills, that lend themselves well to certain tasks. Like finding out just HOW good that new security system your bank paid 50 grand for is. Making that pesky little indiscretion immortalized on the hard drive of a security camera just...not be there anymore. Taking payment in cash and not asking too many questions.
And then there's the new guy.
Marco's got a lot of skills, and some of them are pretty hard to nail down. But there's no denying he's a damn good actor...
My Beating Heart
In which Marco is a friendless college freshman with a penchant for creeping on the guy with the two-toned hair in his Astronomy class. Considering the fact that this is a jeanmarco fic, they'll probably end up becoming friends and, I dunno, maybe fall in love with each other.
Sarcasm aside, this is a lame, unoriginal college AU complete with fun, fluff, and angst. Expect cruel canon references and half-jokes aplenty.
The story of how Marco Bodt offered up his beating heart to Jean Kirschtein.
Kings Upon The Main
There are three kinds of people in the world: ordinary, extraordinary, and statistically improbable. Marco Bodt is one of the unlucky average joes, doomed to a long life of normalcy and predictability. At least, until a wild thing hurricanes into his life, someone who's easily a member of the third category in every way.
Marco's life won't ever be the same, certainly not after Eren leaves it standing on its head.
All The Stars In Texas
Marco Bodt has always wanted to make the history books and has come to the conclusion that infamy looks far better on him than fame. Jean Kirschtein has always wanted to get out of Depression-ridden West Dallas and chase his dreams. A chance meeting throws the spark that sets Texas on fire, and what started as something simple becomes a dangerous game of love, lust, and the birth of living legends.
To put it simply, an A/U in which Erwin and Levi are grown roommates who are essentially terrible at everything, including admitting they have feelings for one another.
Attack on High-School Athletics
"Sina High School was not known for its stellar sports program. It was, however, known for its ability to take everyone else down with it."
Sina High School goes through about a dozen different sports attempting to find a single one in which they can score a win against their arch-rivals, the Titans. Will they stop being abject failures before their school's funding gets butchered?
Beyond Normal Proportions
Levi is a failing artist who publishes a monthly shoujo-yaoi manga called Love Like Caramel. Erwin is his number one fan.
