Twilight Sparkle finds something while searching her old bedroom closet.

When Twilight casts a new spell to detect extraterrestrial intelligence, she doesn't get quite what she was hoping for. Now Twilight is being controlled by the combined efforts of thousands of aliens, and it is up to her friends to help her.

Inspired by the Twitch Plays Pokemon channel that, as of this writing, has been going on for 3d 23h, and has obtained 3 gym badges and is about to reach Erika in Celadon City.

This is a parody of avatar the last airbender, using ponies! Read as the avatar, Twilight Sparkle, travels on a journey to stop the water nation's war against the world. Constantly pursued by Nightmare Moon's daughter as well as the general of Water Nation will she be able to take and complete her first step towards becoming the avatar?

Rainbow Dash is the most epically winning pony there is. She wins so much, she had three epic wins before she even woke up. And with her best friend le Pinkie Pie, how could she ever possibly stop winning...epically?

Twilight thinks she knows how, and the answer isn't a good one. Will she be able to help Rainbow Dash before her epic wins become an epic... fail?

Part of (le) Winningverse (because I said so).

When a freak reading accident causes Twilight to be admitted to the Ponyville hospital, Rainbow Dash is right by her side. Compelled by a sense of duty and repayment, she takes it upon herself to cheer up her friend.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

Rainy weather and a looming deadline drive Twilight Sparkle up the walls and Spike out of the tree. Only Pinkie Pie can save the day, by introducing the reluctant librarian to an unexpected new hobby. Astoundingly, sex does not ensue.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

When Rainbow Dash called for help on her dying breath, she never imagined she would be rescued twice at once. Now she is neither dead or alive, and she definitely doesn't remember wearing all six Elements ...

Rainbow Dash is divided, and she doesn't have much time. To save herself and her friends she may have to convince them to give up the Magic of Friendship, or she can fight ... but how does one fight destiny?
