Twinkie Pie. Appledash. Rareshy. You know these pairings and may have favorites of your own. But what if every member of the Mane Six were paired with every other member in the same fanfic?! That's what the Combinatorics Project is--an epic treasury of fifteen ships spread across five parallel universes increasingly full of plot and whimsy. Can you guess which couple is which?
* The angster and her secret admirer
* The burlesque showmares
* The celebrity marriage
* The commune farmers
* The curse victim and caretaker
* The dessert caterers
* The hopeless homebodies
* The industrial mavens
* The mad scientists
* The masquerade hosts
* The model train overlords
* The multiversal adventurers
* The orchard grafters
* The rivals in love
* The weather aficionados
Plus: Twilight blows up like a balloon and goes out to 'have a spicy time'! Applejack and Rainbow Dash are competitive about everything! Rarity dresses like a butterfly--and later in five outfits at once! Pinkiezilla crushes a miniature town and argues with Octavia about her instrument! Fluttershy dances with an angel and keeps a weather diary! Derpy tells a six-word joke! Not everypony ends up happy, but most do! A little suspense is a good thing. Bitter sorrow! Transcendent joy! Probability cupcakes are cupcakes that cupcakes!
Note: This story was written during Season Two, so a few small things are out of date.

Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

TV Tropes

Most cutie mark stories are happy, exciting tales of finding one's special talent. But not Mac's story. And after Apple Bloom gets into a fight at school, Big Macintosh decides it's time he told her his own cutie mark tale.

Caution: Feels inside.

Applejack, Twilight, and Rainbow Dash really enjoy each other's company. So much so that some ponies are beginning to wonder about them. Twilight and Applejack are a couple after all, so its a bit unusual that Rainbow always seems to be invited along. But sometimes, a couple is more than two.

Instead of landing in the Badlands after the failed changeling coup in Canterlot, Chrysalis awakes in the Everfree, under the care of a certain zebra. She's in no shape to fly or use magic, so she'll have to tolerate her annoying caretaker... for now. But sooner or later, she'll have to leave to regroup with her subjects, and she can't afford to leave any witnesses breathing.

If you ask Applejack, she’ll tell you Pinkie Pie can be a few apples short of a bushel even on the best of days. They’ve always been good friends, but nothing more than that. After all, what could a hard-working apple farmer and a sugar-crazed party pony possibly have in common?

As it turns out, the answer to that question may not be a pleasant one, but something good may yet come of it.

Twilight wakes up with a serious head-ache caused by her horn spontaneously growing due to a sudden increase in her magical power. Nopony seems to have an answer for it, but it has attracted the attention of an unusually powerful militant foreign nation intent on her capture and execution. When a string of events lands Twilight before Celestia's father himself he tasks her and her newfound magic with tying up some loose ends he'd left behind long ago, ultimately connecting with this foreign nation's goals. With their powerful enemy baring down on Equestria, intent on taking it in a stranglehold, Twilight and her friends have little other choice than to travel the world and hunt for the rest of Celestia's family and end several thousands of years worth of feuding to prevent the war coming to Equestria before they themselves are caught.

Gus, an engineering student, suffers a life-changing accident. While trying to recover, he finds himself waking up, being prodded by some sort of black and white animal. The next thing he knows, he's in a hospital with more animals around him and one human... and Ponyville is about to find out just what a scientific education means back where Lero's from.

At least Twilight will be thrilled.

Bellerophon is found on the verge of death at the outskirts of the Everfree Forest. But instead of Fluttershy, Lero is found by Granny Smith Apple along the borders of Sweet Apple Acres. How will this change things for him, and what about everyone else?

In the final days of her life, an exceptionally faithful student muses on the subject of her perfect and immortal mentor Applejack.
