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.

I always wanted to go to Equestria. When I got the chance, I took the deal without reading the fine print. To my surprise, I didn't arrive there as a pony, or even as a human. It seems I get to view this world from a different perspective than what I've imagined.

My name is Echo. I am a Diamond Dog.

A young man named Zach is a U.S. paratrooper during WWII. After a painful turn of events, he finds himself in a very strange land. HiE
This is my first fan fiction so reviews are desperately needed.

Princess Luna, Mistress of the Moon, co-ruler of Equestria, is utterly bored, and tired of dealing with the bureaucracy. When she happens upon an uncompleted spell that promises access to other worlds, she finds a project that engages her as seldom before. Yet, some worlds are not so pleasant and safe as Equestria, and Luna is about to find out how denizens of one of the more dangerous realms entertain themselves as she is thrust into a bloodsport like no other.

The Tournament awaits.

A crossover with Unreal Tournament, specifically UT2k4, which I've come to regard as my personal favorite of the series.
There is some gore, but nothing worse than your usual FPS game made in the last 10 years or so. Rated Teen for that, and some foul language. (Because it wouldn't be UT without the smacktalk.)

Consider this as the soundtrack. Because that's exactly what it is.for Deck 17. So, freakin' EPIC.

When Gilda is thrust into a dark, violent world, she must ally with unlikely characters, learn the importance of teamwork and compassion, and fight the unspeakable horrors of the darkspawn if she ever hopes to survive, for in this world life is not given freely, but is wrested from the wicked.

During a secret mission to the Diamond, an orbiting spy station, Yuri is injured by an unknown force.

He awakes to find himself in a strange world, separated from the rest of his crew, where small brightly coloured ponies talk in a strange language.

How will Yuri survive in a world where only he speaks Russian?

Not all assumptions are malicious, but even the most innocent rumours can be unpleasant, if they actually effect ponies' lives. Rainbow Dash knows this all too well as she tries to confront the stallion of her dreams. A bitter-sweet kind of hilarity ensues when she meets another pony with similar problems.

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

Gerald McCormack, a 22 year old college student that is living by himself with his trusty butler, Gordon. When he stumbles upon a strange majestic-like woman in his own obstacle course--with a pair of Double D's I might add--he takes the woman in, and realizes she strongly resembles Princess Celestia! Will she be able to handle the human world that is so different from Equestria's? Or will she go into a paranoia freak out and Gerald would be forced to kick her out since she seems to be a crazed drug-addict hippy!?

LET'S FIND OUT!
