An undead Emperor in need of a new body. A Spartan lost in space. A ragtag team on a suicide mission. What do they all have in common? They all wind up on the magical world of Equestria, where war has been forgotten. That, however, is soon about to change.
When each of them is about to be retrieved, ancient evils arise to unleash hell upon the unsuspecting world. When the forces of three galaxies clash around them, can our favorite ponies hold out against the onslaught?
This is a crossover involving Warhammer 40k, Halo, Mass Effect and MLP, and is also my first fanfic. Comments and reviews are welcome.

Now with Equestria teetering on the edge of a three way war Ethan is called upon to save Equestria, or at the very least to keep Twilight alive. But dark things are awakening in the background and all is not as it seems, can Ethan save Equestria? Can Twilight keep her friends on her side? Will these questions never stop? The answer to at least one of these is yes but can you find out which?

Now has a Tumblr

Darkness and corruption plagues Equestria. Gangs have sprung up overnight, violence has become the solution to petty disputes. The authorities are powerless to stop the spread of evil. But a hero will rise...

Equestria needs a hero. A hero that is strong, brave, charismatic, and able to penetrate the inner workings of the twisted.

Equestria needs a saint...

Instead it got a drunken madman.

Authors Note: A humans in Equestria story and crossover. My first story so feedback/criticism is highly encouraged. Don't go easy, if I'm going to continue this I need to know how to make it worth your time and my own.

Now with pre-reader DemonRykuKyuubi! Typos should be less frequent.

Having failed to reach Davy Jones' Locker with the rest of his crew, Captain Hector Barbossa finds himself stranded within a hell many times more terrifying; a land infested with magical talking horses and little baby dragons. Despite the odds being stacked against him and the inhabitants of Ponyville at his back every step of the way, he vows to return to his own world and finish the quest he started.

If only fate did not have a new adventure in store for him. An adventure that could very well change the fate of Equestria and the Caribbean seas forever...

After her face and body are permanently scarred, Rarity seals herself off in her room with the lights off and drapes drawn, too disgusted by her own appearance to be seen. The only comfort she has comes in the form of daily visits from Spike, though she keeps the room dark to hide her deformities from the baby dragon. Can he convince her that she has nothing to fear; that her beauty is not limited to what she looks like?

Let's just say your luck with the mares isn't all that great, two months in Ponyville and you've had your heart stomped on more times than you can count. That coupled with the fact you've lost your job, your house, and have barely enough bits to feed yourself means your life isn't exactly going so great. And after another botched attempt at a relationship you're ready to swear off of the whole dating game for good.
But after a night of drunken debauchery you awaken to find yourself in the service of Ponyville's premiere fashionista, you're willing to forget your previous pledge to the single life after she proves herself to be the kindest and most generous pony you've ever met, but only time will tell if she'll be your future lover or the next in line of a long list of mare's who you'd rather forget.

Spartans never die, they're just missing in action. This has never been more true for Jorge-052 as, after activating the slipspace drive that was supposed to kill him, he is instead flung into a strange world where war is but a distant memory. Will the aging soldier be able to adapt to this new peaceful planet? Or will his only salvation be found in finding a way back to his own chaotic universe?

(It's my first time, so be gentle)

Humanity has had the urge to learn and understand since the dawn of their species as Homo Sapiens. From the first telescopes and the study of the stars by sailors, to the colonization of new worlds, Human beings have pursued the unquenchable thirst for knowledge in all of its forms, no matter what the cost.

Now, in the year 4025, long after Humanity began expanding their reach into the deep expanse of space, a new world is found that defies all laws of physics and reality...
