Celestia and Luna are both suddenly reverted to their younger years. Centuries of wisdom and intelligence are muddled by confusing hormones and urges, and are forced off the throne thanks to a rule setting an age limit.

Can Celestia and Luna cope with being fifteen again?!

(Yes they can.)

What are their plans to reclaim the throne?!

(Hint: it's party like they don't care.)

Big Mac was vaguely aware of Applebloom holding his head during his seizure, of her trying to talk to him, but his head was filled with another conversation.

After a magical accident, Big Mac ends up in an alternate dimension. A world where humans are the dominate species, and horses are put to work. This is the story of a common horse, told through the eyes of an uncommon pony.

You'll never understand a pony until you walk a mile in their horseshoes. Or more appropriately, until a magical goddess forces you to switch bodies with the other in an effort to force the lesson upon you. That's right, its a body swap fiction! Starring everyone's favorite musical ponies, Vinyl and Octavia! (Partially narrated by Princess Luna)

And they'll need all the help they can get.

I've marked this story as cancelled to reflect the unlikelihood of it continuing. If I do come back to it I'll revert that.

A mysterious brown Earth pony with an hour glass Cutie Mark sneaks into Canterlot Castle, only to be caught by Princess Celestia herself. Curiously, Celestia is intrigued by the seemingly endless stream of nonsense this pony is wont to speak. Luna soon joins them, and the group heads into the very depths of the castle, where something has been lurking for far too long...

Author's Note: The story begins with Season 1 Luna, weakened and with very little magical power, as well as having 'flat' hair.

Doctor Whooves is also an Earth pony in this fanfic, as he has appeared as both a Pegasus and Earth pony in show.

Co-Authors: Bramble Rose, MudBug, Diomedes

The Eleventh Doctor (aka Matt Smith) is bumbling about in his Tardis when a crazy timey-wimey happening finds him in Equestria, a land from a children's cartoon. Despite the idea that being in the world of TV ought to be impossible, he's found himself turned into a bowtie-wearing pony in a pleasant little town known as Ponyville. What's more, the people there won't stop calling him Doctor Whooves! In order to get bet back into his own Time Lord form and out of the impossible world of My Little Pony, he may or may not have to make some new friends, fight some villains and pull out his "savior of the universe act." Geronimo!

This is a different take on Doctor Whooves, and also a sleep-deprived Doctor Who/MLP crossover idea I got in the very early hours of the morning so it could easily be rubbish. It's not meant to be terribly serious, but it's also my first fic so go easy on me. More characters could come and the rating could possibly change.

Title says it all. Time travelling shenanigans ensue.

It's been ten years since Rainbow Dash's father disappeared in a wild, fierce thunderstorm. When the same strange storm hits Ponyville, Rainbow Dash does as much as she can to try and stop it from happening again.

But magic has a strange habit of making things reappear, opening old wounds that could change Rainbow Dash's life forever.
