EDIT: First and probably only ever, added Author's Notes to address the frequent "Were means man" issue. Please read them before commenting.

"Fluttershy gets bitten by a werewolf from the Everfree Forest, but when a side effect of the changes limits her inhibitions, she starts to wonder if the cure is such a good idea. Even if she does start to behave a little 'differently' otherwise..."

A one-shot story in the spirit and style of an episode of the show itself.

(With one small edit to fit details of the story)

Life in Ponyville, outside of the usual events like a parasprite invasion or a revenge-seeking, all powerful megalomaniac kicking out the town librarian, tends to be laid back and typical. Which Applejack doesn't mind. However, after the CMC cause more problems due to influence from a newcomer in town, Applejack gathers the girls to go fix what the CMC did.

But then a mysterious creature ends up attacking Applejack, and while she survives and seems fine, it isn't long before she starts acting strangely. It's up to the usual group of ponies to figure out what's going on before it's too late.

Twilight Sparkle had been looking forward to a quiet, relaxing day with a friend, and at first it seemed that Fluttershy could provide just that. But when Twilight makes a rather unsettling discovery about the pegasus – and her unusually sanguine appetite – the knowledge proves to be anything but relaxing...

A letter from Celestia interrupts one of Pinkie's parties with disturbing news. Now friendships will be pushed to the limit as Twilight struggles to uncover which of her friends is not who, or even what, she appears to be.

(While not a romance, this does contain a shipped pair)

in Russian

Twilight decides to go out for a friendly night of drinking with her two friends, Pinkie Pie and Fluttershy, to relieve the stress of planning her brother's wedding and defending Canterlot against the changeling invasion, but not all is as it seems.

A letter arrives in the middle of the night, informing the unicorn that one of her two friends has been replaced by a changeling.

What are the chances your favorite pony was secretly a changeling all along?

Yeah, probably about one in one.

Twilight Sparkle regains consciousness thanks to Discord only to find she and all of Equestria have been transformed into changelings by Chrysalis, with Canterlot as her new grand-hive. A weakened Discord gives her the help she needs to locate her friends and attempt to snap them out of their brainwashing, while Luna leads the remaining ponies in a struggling but stubborn resistance against the love-feeders. How long does Twilight have before she succumbs to the changeling's hunger again?

Sweetie Belle is a normal filly, at least she thinks so. But even among her fellow Cutie Mark Crusaders, she had always been different. Maybe it was some slight bouts of immature behavior or taking after her older sister. But lately she has felt some strong feelings looming over her, she knows why but won't tell a soul. She won't even be honest with her self. So what does she do? The choice is obvious: She hides. She hides from friends, she hides from families and teachers. She hides her feelings where they can never pop out and ruin what life she has. But is hiding enough?

Warning: This story deals with things of a slightly mature and definitely 'taboo' nature. I would say exactly what it's about but it is a mystery, just don't be surprised if a few chapters in your brain explodes.

Note: Sorry if your brain explodes.

A pegasus woke in the woods. He was lost, injured, and had only the vaguest of dreams for memories; nightmares of a Canterlot engulfed in shadow and flame, of an invading swarm lead by one great and terrible dark figure. As he begins a new life, the dreams continue to taunt him. Will he ever find out who he was? And if he does, can he -- and his newfound friends -- accept what he finds?
