ALL MLP characters Humanized. Equestria and the rest of the world have achieved certain inventions. Cars, Planes, Phones and stuff like that.
Sorry for the terrible description.

((The idea from this story was taken from chapter 12 of Gravitys Rainboom fantastic story: MIA. I've talked with the author, and he allowed me to write this story, since I feel as though it will be somewhat similar.))

This story has been cancelled! You can discover the ending (last story on the page) HERE

They say that Spartans never die; that they're only missing in action. But can that really be true if you don't feel alive? If the very purpose of your existence is suddenly taken from you?

Noble Six detonated the rigged slip-space drive on the Covenant corvette as Jorge-052 simply floated back down to Reach, gripping her dogtags tightly.

To Reach, Jorge, and the UNSC, Spartan-B312 is gone; whether it be KIA or MIA.

But to Equestria, Noble Six is anything but dead...

Medicant Bias, the once rampant Forerunner AI that joined the flood to destroy his former masters, is now trying to show that he is, once again, serving his masters, even though he knows that his sins were too great to be absovled too easily, he is going to try to help in any way he can... even if they are technicolor ponies.
What will happen when he gets somehow teleported to a foregin world full of magical creatures? Will he be able to redeem his past sins and help these ponies?

During a playful conversation two friends accidentally open a portal to a different world and are forced through. They find themselves in Equestria and as ponies which in and of itself isn't terrible, but it turns much worse when they realize that they are children as well. Now they have to figure out a way to outsmart Equestria's Social Services, get along at school, earn a living, and keep up their cover as an independent set of brothers; all while trying to figure out how to get back to Earth or at least make themselves their proper ages again. Puberty sucked enough the first time around.

6/6/2014 Just hit the first time this story has been in the featured box. Thanks everyone for reading and supporting.

When a strange being crash land onto Equestria and claim to be Rainbow Dash. The Mane six was skeptical, was this the same Rainbow Dash they knew? Or was this some Changeling's pathetic attempt to infiltrate into their lives?

To gain the Mane six's trust, Rainbow Dash talk about her tales of traveling through out the cosmos, jumping into hell, making new comrades, cracking some butt-ugly alien skulls, getting shot, losing friends on the battlefield, and then back again.

One of these days though, you wish you’re really dead. But hey, it’s like what they say… Only Death Stops Them.

Thanks to all the proofreaders Man Of War, Katherine Kerensky, plainoasis and Identity for helping me out with the story.

My first story. So criticize if you will (which is good) but please, don't stir up a flame war down there.

More tags will be added as the story progresses.

Disclaimer: I do not own either the franchises Halo nor My Little Pony. They belong to their respective owners and this is just a work of fiction.

When the Elements of Harmony defeated Discord, they did their job too well, and completely undid all of the things Discord directly did...

... Like send a subcontinent from earth into a pocket dimension so he could focus properly on his toys. And now Equestria has appeared on Earth.

Yet, neither side was completely ignorant of the other. On Earth, there was the show "My Little Pony: Friendship is Magic" and in Equestria there was the ever popular movie serial "The Dark World: Technology is Courage" which was a favorite of colts everywhere as well as the "Pumans".

And now both sides learn through an event that the other is real. Come join us as we watch as both sides learn to work and live together. And as they find out that events on their respective fiction was not as nice as it seemed as we widen the lenses of the view points...

A Round Robin created on SpaceBattles of which I am a participant and am posting with all their permission.

Death. All that remains on this planet are the martyrs who gave their lives to ensure the others could escape. Humanity’s greatest has fallen. 23 Billion humans died in the war, and only more would follow. The few strays on Reach were quickly found and slaughtered. The last soldier died fighting, a fitting tribute to the planet humanity fought so hard to protect. Still, the story is not over for mankind, just as the story is not over for this lone soldier. This, is the story of Noble Six.

Coin Slot, a slaver in the Equestrian Wasteland, is making just a regular sale when something a few miles away explodes violently. Deciding to check it out, she discovers a strange weapon of unknown origin that seems to mesmerize its targets. There are... drawbacks to this weapon, however, and its discovery soon leads Coin down a chain of events that will change her morals, lifestyle, and even her very soul... provided that she manages to survive. Will the friends she makes be enough to convince her that her slaving ways are immoral? Or will they just reinforce the belief that that is one of the best ways to survive After the End?

A side story of Kkat's Fallout Equestria. Which is excellent.

The Pillar of Autumn wasn't the only ship that left Reach when the UNSC withdrew from the planet. The UNSC was desperate to find a planet to settle on where they can effectively hide from the covenant and recover from the near fatal blow they suffered on Reach. When the Hall of Heroes, a ship similar to the Pillar of Autumn only smaller, finds an unexplored planet away from the covenant empire, they
immediately launch a recon mission to confirm if the planet is habitable, Mikel Dakre and his ODST team find more than they bargained for.

(SPOILERS IN STORY AND DESCRIPTION)
Wheatley is trying to get Chell to jump into the pit of nothingness, and she doesn't listen until Wheatley says a pony farm is down in the pit, so Chell jumps down and is teleported onto Applejack's farm. Not too long after, Wheatley begins to question himself what happened to Chell and POTaTOS. He ends up sending a turret named Annabelle (my character) into the pit to see what in the name of science is going on down there, when things take an unexpected twist...

Made Teen for swearing.
