Canterlot... For centuries, Canterlot was the shining gem of Equestria, the pinnacle of pony society. Now, it’s a reminder, a bleak and monolithic warning to the world. 

Changed by the chemical and technological poisons that plague the mountain, an abomination of nature, I wander the greatest disaster Equestria has ever seen. 

... I will escape eventually, and when I do, I hope my friends still see me as Twilight Sparkle, and not the monster that hides among the ruins. 

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 an unknown accident Twilight Sparkle and Rainbow Dash awake to find themselves sharing the same body! Now they must struggle to hold themselves together as their world is turned upside down. How long can two ponies exist in a single mind? It’s a race against time as they search for answers before it’s too late. When all is said and done, you’ll never look at Twilight Dash the same way again.

Ponyville faced an ordinary day, but then night came, and with it a massive gateway into another world. It closes before any action can be taken, but now the Mane Six and Canterlot nobility are tasked with finding out what they can about the gateway. Who created it? Where did it lead to?

And most importantly, did anything come through?

Takes place after Season 2

When the severely damaged Galactica makes an emergency blind jump away from the Cylon Colony, it encounters a strange new world of magic and talking ponies. The Colonials, desperate to settle down on a new world, are eager for the chance to put their troubles behind them and start anew on Equestria, but humanity's violent past makes many on Equestria nervous. Despite the fears of the planet's native inhabitants, the Colonial military cannot simply lay down their weapons only one jump away from the Cylons' former home base. Because the desperate, dying remains of the Cylons are still out there, and even a dying beast has sharp claws...

Note: I'm not even going to try to explain all the ridiculous plot twists of neo-BSG. I'll try to make things understandable to everybody, but those who haven't seen the show will likely miss out on a fair amount.

Okay, so I pretty much did this on impulse. I've never really been a part of the MLP fanfiction community beyond reading stuff, and I know my writing probably leaves a lot to be desired. If anyone is interested in helping me with editing/pre-reading, please contact me.

Also, this story contains references to AdmiralTigerclaw's story "Higher Flyer", which you should really read anyway because it is awesome.

When a supposedly-Forerunner artifact activates on-board the UNSC Guam, turning everyone on board into ponies, It sets in motion a clash of forces, ideals, and dimensions that could save humanity in its darkest hour, or doom the peaceful land of Equestria to burn in a war never meant for them.

This story starts some time before the season 2 finale, but after the other episodes of season two. Season 3 stuff will only be used if I find a reason for it/don't think it's OP (I'm looking at you Twilicorn and Mirror Pool.)
This story also takes place before Halo: Reach, so don't expect things to stick very close to the games.

Minimalistic cover art was made by me in Microsoft Paint, because I have buck-all else to work with.

Character tags will be added as they become major players.

Marcus Fenix has known almost nothing but war his entire life. It has consumed every aspect of his existence, and it has torn his world apart. After years of fighting and sacrifice, the tides have finally started to turn in favor of humanity. But after their most recent mission goes horribly wrong, Marcus and Delta squad find themselves in a bright world so very unlike their own. Surrounded by a myriad of talking ponies, can the hardened soldiers come to grips with the innocent nature of the realm they now find themselves in? And what will they do when they discover that all is not well in this naive new world?

(A/N: This story takes place before the events of Gear of War 3, and between seasons 2 and 3 of MLP: Friendship is Magic. I've never read most of the supplemental material for Gears, so forgive me if I get some of the background stuff wrong. I'll do my best to research it/correct myself.)

SG-1 is sent through the Stargate as a forward scouting team for an extended scientific mission to P3X-597. Arriving in a long abandoned castle, the team heads out for the nearest village. As they approach, it becomes clear that the locals aren't exactly human. Their contact with the pony-like aliens goes well, conveniently timed alongside a celebration of the sun, until an over-the-top, hammy, evil pony appears to ruin the festivities.

A Stargate SG-1 crossover.

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.

(Post-Mass Effect 3)(FemShep)
When the Reapers were defeated, the galaxy believed that Shepard and Anderson were both lost in the final battle. However, the two long-time friends were also known for not letting death stand in their way.

Waking up, in the middle of a desert, on an uncharted planet they both embark on their strangest mission yet. Attempting to find their way back to the Human Alliance, a place called Canterlot may hold the answers they seek. But first, they had to get there while trying not to draw too much attention to themselves.

Too bad for Anderson since massive explosions and collateral damage followed Shepard wherever she went, without fail.

Crossover of My Little Pony and Mass Effect.
