Two thousand years after the return of Princess Luna, Equestria's technology and magic has advanced far enough that the once far off dream of faster than light travel is now a reality.

And that reality is the ES Harmony, the pride of its designer, Princess Twilight Sparkle, and Equestria's first FTL capable starship. It is due to make its maiden voyage to travel further than anypony before it.

And yet when they receive a distress call from origins unknown, this ship's maiden voyage will become one the crew will never forget.

(Not a strict crossover with Star Trek, but here Equestria Girls takes place in the Star Trek Universe)

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

Pinkie Pie and Fluttershy thought they were going to help banish Discord for a third time with their friends and the two princesses. That was precisely what was happening until they both found themselves suddenly transported to a strange new world under a flashing pink sky.

A man named Doug "TheSlorg" Collins finds two young women who are naked, confused, and smell of fudge in the Australian Outback. He then reluctantly agrees to help them return home. But when "home" turns out to be Ponyville, things become a bit more complicated than he bargained for.
