Based on a true story. Kinda. Not really.
A man named Jason previously led a rather melancholy life before he died violently. No surprise there. But as he wakes up in Equestria and is thrown into a foreign body, he is forced to survive with the guise of a changeling. Taking place shortly after the failed changeling invasion of Canterlot, how can he keep from being revealed by new security measures, and blend into this new world, while making use of the most unlikely of allies? But of course, avoiding ponies only turns out to be the easy part when trouble has a habit of reading its ugly head. Really though, what could go wrong?

Props to the ever epic Zubafa for his cover art.

When Legion uploaded the Reaper code to the rest of the Geth, where did his "soul" go? Geth never had an afterlife, but when Tali confirmed Legion indeed have a soul an unexpected turn of events leads to Legion's life. It must integrate twenty-second century science with the science of old human ages, while finding its true self once more.

Mass Effect belongs to Bioware and EA.
My Little Pony: Friendship is Magic, belongs to Hasbro and Lauren Faust.

Basically, the Doctor has been a pony for quite some time now, and he's even got an assistant-Twilight Sparkle! But, things change when he meets a pony he's never seen before, and quickly falls head over heels. My first fic, so be nice.

Marcus 657 has always been different from his other Spartan brother and sisters. Most are broken at the core; no longer fully human in a sense. But is there still redemption for this Spartan? Can Marcus regain his humanity through old 'gifts' and new friends? And perhaps love in one of the oddest places?

This is my first story, so be nice. If you favorite it, don't forget to press the like button. Thanks for reading!

When ED-E's circuits burned in the fires of the Divide, there was one small part that held on until the end. It was the fragment that held the Old World memories and the words of his creator in his last moments. At lest that would've happen if a weird man didn't pluck ED-E out of Earth and drop him in the middle of a strange place for some bizarre reason.

Rated Everyone (yes a Fallout crossover that's rated everyone). This is just a silly little idea in my head. Hopefully y'all will enjoy it. Also thanks for HeavyMetalCommunist for proofreading.

Edward and Alphonse Elric are tossed into a world of chaos after they attempt to regain their bodies using a faulty Philosopher's Stone. Can the famous Alchemist and his brother make it back to Amestris? Or are they stuck in Equestria forever? Read to find out!

I'm rewriting this. It was pretty bad before. Hooray for second chances! Right? Right??

Jak and Daxter have found a new Rift Gate. It leads to a land full of... ponies?

One thousand years ago, shortly before the advent of Nightmare Moon, Princess Celestia and Princess Luna bore witness to twin vessels descending from the stars. Fearing their power and mystery, they were quickly sealed away where they lay. Now, in the present day, a freak accident caused by three unknowing fillies has broken the first seal in the Everfree Forest. Were the Princess' fears warranted? Or were these behemoths indeed "More than meets the eye"?

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.
