Animals all across Equestria are being possessed by the spirits of humans.

complete and utter anarchy ensues.

It is the year 2552 and the Pillar Of Autumn has just entered Slip space to escape the Covenant fleet at Reach. A malfunction occurs with the Slip space drive and sends the Autumn and her crew into unknown space. The first planet that comes into range is very Earth like, and is giving off intelligent life signatures. What they don't know is that their only way back home is on this planet. The Autumn dispatches a scout party and what they report back is unbelievable. A world completely inhabited by ponies, millions of them..... Welcome to Halo: Equestria.

I'll add in more character tags as they are introduced in the story.

Spartan A-042 finds himself on a mission gone wrong when he winds up in a land of talking ponies and other magical creatures as he struggles to comprehend how he got there, why he is there and above all, how can he leave.

It has been several months since the disappearance of Twilight Sparkle..

One night, after watching her sister raise the Moon and set the heavens alight, Princess Celestia begins to bed down for the night, only to be interrupted by portal forming in her room. From out of the portal comes none other than Twilight Sparkle, garbed in strange armor.

Princess Celestia, along with Luna, Cadence, and Shining Armor, are overjoyed by the Element of Magic's return, but are justifiably curious as to where she had been and what she had been doing. And so, Twilight begins her tale. A tale of survival against impossible odds. A tale of a people fighting for the most basic right of all sentient beings. The right to exist.

Years drifting in space aboard a frigates wreck with nothing to do but wait and think can really wear an AI thin, and when that AI is already past its expected rampancy date, all that thinking time is dangerous. Very dangerous. Fortunately for Cortana, the frigate is pulled into an unknown planets atmosphere, allowing her to take her mind off of rampancy for a while. After being rudely awoken from cryo sleep, the Master Chief, along with Cortana, manages to escape the burning vessel. They have very serious problems though...

They have no idea where they are, or how they'll get back to Earth.

They can only hope someone finds their distress beacon, and fast. The Chief doesn't have many supplies, and with a rapidly decaying AI in his head, he has a lot on his hands. Luckily for them, the planet is life supporting. Unfortunately though, the inhabitants of the strange planet aren't the most welcoming of a seven foot tall alien, especially when that alien is as aggressive and lethal as Spartan-117. The Chief has only one objective, find a way off of the planet. The inhabitants will soon learn, however, that the Spartan is extremely aggressive, and will stray slightly from his objective to harm them if he must. Chief also learns that these beings are no pushovers, and will defend their home and kingdom with their lives.

The first few chapters are mostly to establish a plot, there will be much more action after them. This is also my first fic, so constructive criticism is appreciated. I will be reading the comments quite thoroughly for the first while, so you may see some of your ideas in future chapters. I am only 15 years old, so basically, I have school, homework, and sports that will quite often get in the way of this story, but I will work on it as much as I can when I can. I won't give up or quit in the middle of the story despite what the ratings may be, and last but not least, I won't be turning this into some huge cliche war where Equestria ends up fighting the UNSC and whatnot. Because Equestria would get screwed. Badly. Then the story would be ruined, so, I hope anyone who reads this enjoys!

I do not own the Halo franchise, My Little Pony: Friendship is Magic, or Forward Unto Dawn.

Story added on October 25th. Edited by myself, and inspired by Halo: Ponies and Clouded Pasts by Blazer and The Mercy, Regret, and Truth by Master 4871.

PS: This made it into the featured box the second day it was uploaded, and remained there for a couple weeks. I'm pretty damn proud of that since this was my first fanfic ever, and the first thing I ever posted anywhere. The only other people to read my creative writing creations were my English teachers and occasionally my grandparents and father. So seeing the first thing I submit get such great feedback and a huge amount of views (huge to me), is just amazing to me.

Thanks, bros.

The year is 2557 AD. Four years, seven months and ten days have passed since the activation of Installation 04B and the annihilation of the Flood. While humanity and the Covenant have struck a truce for the time being, and started to rebuild their civilizations, Master Chief Petty Officer Spartan John-117 has been in cryo-sleep, adrift, while his ancillary AI, Cortana, has been trapped in her own thoughts. She had been looking for a reason -- any reason -- to wake the SPARTAN up. Now she had one.

They were crashing.

{Description Edited 4/25/2014: Clarified Installation 04B}
{Edit 05/02/2014: Trimmed character list pending future change}

What's it been? 1000 years?
That's funny. It feels like much longer than that.

Let me tell you, being trapped in stone that long can do crazy things to a guy.
And when you were a little off your rocker in the first place...
But now I'm free. The leaders of this disgusting place trapped me here, and now they're going to pay.
I'm going to show them the real definition of insanity.

Dusk the Riolu was once an ordinary wild Riolu living with his mother, until a great accident made him loose his mother and sent him to a world of ponies. Will Dusk learn to live in this new and strange world, and will he be able to reunite with his mother once again?

Rated Teen for Light Gore and more Adult themes.

Spartan Adam-D014 was a lone wolf assigned to the UNSC Lightning. What was supposed to be a routine mission ended up with the frigate being ejected from slipspace unexpectedly, and with Adam landing on a strange planet inhabited by colorful, friendly equines. But something's not quite right... Adam's turning up in Equestria was more than mere coincidence, and Adam is determined to find out just what is going on.

Enjoy!

Twilight's hiccups were bad enough when they were interfering with her work... Then she made an attempt to cure them, only for another, poorly timed hiccup to botch the spell.
Now her hiccups randomly summon creatures—primarily humans—from other universes... Creatures with absolutely no connection to one another.
Including, but not limited to...
A boy with a silly pink hat...
A super-powered little girl in a blue dress...
A boy with an alien, watch-like device on his wrist...
and a peppy cheerleader carrying a brightly-decorated, blood-stained chainsaw.

Now Twilight needs to cure her augmented hiccups and return these visitors to their respective homes, before the library is flooded with these guests... or the more "raucous" among them decide to stir up trouble, for both Twilight and Ponyville as a whole.
