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.

Twilight and her friends fall victim to yet another one of her spells, sending them to a dimension in which they must trust a strange pony who only goes by 'The Doctor' in order to get back.
And a drunk pony wants scotch.

A perfect day in Equestria. Applejack and Rainbow Dash are racing. Rarity is making a new dress line. Twilight Sparkle and Fluttershy are busy making new magical foods for Fluttershy's pets and all of the friends are planning to end the day with a nice picnic in Sweet Apple Acres. All of which may change when the hear that unmistakable sound of the legendary Tardis which lands right in the middle of Sweet Apple Acres. What will follow the Doctor is unknown but what is known is that Equestria will face a foe like no other.

When Twilight comes back from her week long visit to her brother's house, she finds out that everything has changed. Canterlot High is babbling about some magic girl from another world, but Twilight knows better. There's no such thing as magic, or portals into other worlds.

Right?

EDIT: Wow. Never expected the feature. And by the way, thank you for anyone who commented with a consructive criticism. I'll be reading as many as I can and keeping them all in mind for the future chapters as well as going back to edit the past ones periodically. Enjoy the story!

EDIT 2: Went into the first chapter and tried to fix up the 'Twilight did X' issue that many people commented on. (Thank you to those who did.) Hopefully it is a bit more readable now.

EDIT 3: After fan feedback on a massive error I made where Princess Cadence was an out of control lunatic, I rewrote the Twilight meets Twilight scene so that it flows better and actually stays in character. Thank you for anyone who made a comment about this, I am listening to your feedback and writing my future chapters accordingly. (If there are any more of these, I'm going to keep these in a changelog in a blog post.)

We all know that Twilight Sparkle went back to her own world after she defeated Sunset Shimmer. They know it too. So why is it that on their senior trip they see a girl that looks exactly like her?!

After losing a good friend who will no longer remember him, an incident in the TARDIS causes the Doctor to get stranded in a parallel universe. Instead of just another parallel earth however, he finds himself in the world of Equestria where ponies rule. While the Doctor tries to get his head around the concept of magic, and Twilight sparkle tries to understand the TARDIS, a disaster occurs when the Doctor inadvertently reveals a terrible secret, and an old foe from the Doctor's past will try to take over Equestria. The Doctor and his knew found allies our the only ones who can save the day.

Kingdoms come and go, civilizations wither and die, and time delivers us all to the same end. History has shown this is often the case, but there are always those who seek to prevent this by any means possible.

Equestria has existed for more than a thousand years having faced civil wars, secret invasions, alien threats and the wrath of gods. After several recent attacks on the country, faith in the monarchy has fallen to an all-time low. On top of that, an ancient enemy threatens to not only destroy Equestria, but the entire planet as well. It would normally be up to the elements of Harmony to prevent certain destruction. But what if the threat was something that threatened to undermine the monarchy if its existence was known, even by the elements?

There is only one option, a new team must be formed, a league if you will.

The powerful, the odd and the downright bizarre are called together to prevent a catastrophe that doesn't just threaten Equestria, but the entire world. At the same time, they must prevent a thousand year old lie from being uncovered that threatens to destroy Equestria from it's very core. Can a group of such volatile individuals coexist? Or will their inability to trust each other lead to the downfall of all?

The Doctor has had a good, long run through time and space with Ditzy Doo. But it is that time again for him to regenerate bodies. But this time, it seems... different...
What would happen if The Doctor regenerated... as a mare?

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.
