That's right, the Joker, otherwise known as the Clown Prince of Crime, the Harlequin of Hate, and the White Duke of Death, is now in Equestria. Will this unpredictable, murderous psychopath learn the true magic of friendship and abandon his old malicious ways? Or will his arrival kick off an unstoppable crime spree to shape Equestria into his own image? Like I said, the Joker is unpredictable.

Special thanks to my awesome prereaders X19, LDSocrates and The Alpha, who are the best of the best! Read their stuff or just thank them for reading my unedited monstrosity before I release it to you guys!

Now on TV Tropes because of the greatness that is Shadow Sora94. Give him some thanks!

When a mysterious magical mist transports Equestria into the Human World at the beginning of the 20th Century, everything is turned upside down. Alliances shift, governments are toppled, new technological discoveries revolutionize daily life and the same mysterious force that brought Equestria to Earth is not done with it yet. On top of that can Equestria's ponies learn the long forgotten art of war? Can Equestria survive the most violent century in human history? Or will it be torn apart from both without and within? As the old Chinese curse goes. "We live in interesting times." (Currently cancelled. With no plans to restart it later.)

There is a flood on the horizon. Equestria's enemies have united, and the coming tide will not only change the course of history on one world, but two, and bring about a monumental meeting that will bring brothers and sisters from those two worlds together.

At long last, the downtrodden will rise.

The battle begins.

A Ghost. A weapon. A tool. That's all he's ever known himself to be.

One day he's sent on a mission, a mission to assassinate a high priority target. When he fails that mission, and gets abruptly sent to a certain planet, how will he cope with being taken from the battlefield, and put into a world full of colorful horses that talk?
...
And will he have access to a Tactical Nuke?

Only time will tell in this tale of adventure and comedy!

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.

Two months have passed since House faked his death to avoid prison and spend time with his best friend, Wilson. Together they have traveled the United States doing whatever it is Wilson wishes to do before he dies from terminal cancer.

The most recent decision was to go to Trentville, a small town with little to offer the pair, apart from an unbeatable drinking challenge.

After successfully completing the challenge House and Wilson pass out in an an alleyway behind the pub, only to wake up in rather different land.

How will House cope in a land that is filled with ideas he believes to be moronic, where kindness and friendship roam free. More importantly, how will Equestria cope with House's cold, hard, cynical logic? Also how will Wilson cope living in a land filled with ideals he has tried to convince House of his whole life?

They came to Earth in peace, all but looking for salvation. The world greeted them with open arms. The... Ponies... Were all nice and cheerful. Until... They wanted to take over the world, saying it is unfit for humanity. They attacked. They killed. They... Made humans into ponies. Humans fought back, but crumbled soon after. Except one. He fought with Queen Solar and Heaven King; Celestia and Luna's Mother and Father. He lost and was sealed in ice for two thousand years. Now he's back, and his trigger-finger is itchy for war.

DARPA, the Pentagon's team of mad scientists, have cooked up something interesting. A portal to another dimension? Why? Better question- why not? Somehow sensing a military application from this, generals from around the world cobble together a task force to go investigate this new land and mark sites for later exploitation. Backed up by the fury of the world's modern military forces, they launch their operation into this strange realm. When they discover a bright, happy universe full of talking ponies, they realize the folly of what their mission is. How will Equestria react to people whose confessed profession is being expert fighters? Matter of fact, how will Equestria react to PEOPLE?

A crossover of Red Vs Blue - the Halo Machinima series - and My Little Pony: Friendship is Magic, primarily starring Epsilon, who is recaptured within the Epsilon Unit and finds himself in the land of Equestria. Will the resident ponies and him become best friends, or will the situation degrade into a flurry of insults?
Hedge your bets, folks.

Having lost the Overlord some time ago, the long-lived advisor imp, Gnarl, and the all of the other minions toil over their loss. This Overlord, was perhaps the best of all compared to the past ones. During this time though, they have found a spell in a tome that may re-unite them with their master. But smally printed in the dusty and aged book, a message states that the spell comes with mixed results. Will they bring back their master? Will they fail? Or, will they re-unite in a mysterious new land ripe for plundering?

This is a satirical comedy of regular stories of heroes against villains. This story, instead of regular ones, features the villain as the protagonist and the heroes as antagonists. If you enjoy a story in which the Mane 6 are finally shown as vunerable instead of invunerable whenever dangers appear, feel free to take a gander yonder.
