What would you do if you knew everything, about everyone, just by looking in their eyes? Every dirty secret, every happy moment, their very soul laid bare for you to see. Could you keep your sanity? I don’t have much of a choice, if I go crazy, I don’t know that I can do anything to stop it. But, maybe someone else can. You see, there’s this filly, and she drives me up the walls, but I followed her through a door that doesn’t want to close. Thing is, I’m not sure if I want it to.

What would you risk for the chance to have a friend? How many doors would you cross? I'm about to find out.

Note this story was previously canceled and has now been revived.

A Metroid crossover.

After destroying the X, the Galactic Federation charges Samus with treason and hunts her down. While running from the Federation, Samus manages to escape but ends up crashing in Equestria, far from any explored sector in the universe and with no way of returning home. Can the most feared bounty hunter in the galaxy adapt to a land full of talking, magical ponies who think friendship is magic?

Some notes:

1. This takes place after Metroid Fusion, which is the last game in the Metroid chronology/timeline so far. It also takes place after season 2 of My Little Pony: Friendship is Magic.

2. Samus crash lands on Equestria and meets the mane 6. I'll try to not make it too cliche. Also, no ponified Samus (at least, not planning to).

3. In this story, Samus is a Federation runaway. They are hunting her because she destroyed the X parasites in Fusion and they wanted to research on them (I recommend checking the Metroid Wikia for reference).

4. I'll take the 'Tragic' as not so tragic. Don't expect deep depression from this story.

5. I'm open to ideas! Any review/comment is greatly appreciated. Feeding my ego will increase the chances for updates!

6. Any story inspired or ripped off from this story WILL catch my attention. Please tell me if you are going to write one, so I can read it!

Without further ado, enjoy!

Part 1: Lyra's Pyro Predicament
Part 2: Twilight's Demoman Devastation
Part 3: King Sombra's Robotic Retaliation

King Sombra was soundly defeated by Princess Cadance and Shining Armor almost a year ago, and the Crystal Empire was free. Now, after a teleportation mishap, a lone Engineer from Gray Mann's massive robotic army has found itself in the mountains just on the border of the Empire with one task in mind: complete the experimental Lvl. 4 Teleporter and bring the robotic forces to Equestria...but what other dark forces might be laying dormant in those caves?

Part 1: Lyra's Pyro Predicament
Part 2: Twilight's Demoman Devastation
Part 3: King Sombra's Robotic Retaliation

After receiving a strange book from Pinkie known as "The Bombinomicon", Twilight wakes up one morning to find that the mystical tome has been stolen, by...Twilight?

Things quickly unravel as RED Team's Tavish DeGroot (Demoman) and Spy find themselves not only trying to get back home, but also fighting for their lives as villains from the Team Fortress 2 universe combine forces with some of the most dangerous foes Equestria's ever seen!

Part 1: Lyra's Pyro Predicament
Part 2: Twilight's Demoman Devastation
Part 3: King Sombra's Robotic Retaliation

When a mishap causes two para-dimensional weapons to colide with one another, RED Team's Pyro is sent flying from the Team Fortress 2 universe into the alternate universe of My Little Pony, where he is almost instantly discovered by Lyra, who shelters him in her home.

Having him hidden in her small townhouse isn't easy; keeping him from setting things on fire, teaching him that not every cart that passes by is cause for alarm, and that blue ponies are not something to be suspicious of.

However, with Nightmare Night soon approaching, Princess Luna feels that there may be something more sinister riding on the coat tails of Pyro's grand entrance; the first human to ever set foot in Equestria some thousand years ago...

This story is a sequel to Better Living Through Science and Ponies

THIS STORY IS CURRENTLY BEING REWRITTEN. PLEASE READ:
I've decided to rewrite this entire story. Considering that I began this project with almost no creative writing experience, I was bound to make some pretty bad mistakes. The story flow is not well organized, and there is an unhealthy amount of redundancy and poor pacing, as well as some pretty important things that I should have included. I intend to address these issues to the best of my ability, but it will be a long and arduous task. This story means a lot to me, so I want it to be more than the mere amateur mediocrity that it resembles. So, give it a read if you want, but keep in mind that it will change. I recommend that you put this on your read later list in the meantime.

This is a Portal 2 crossover. If you haven't played Portal 2, please do that first. Then read the prequel if you haven't done that either.

After Chell finally escaped the confines of Aperture Science, a freak portal mishap down below transported her, along with the entire Enrichment Center, to the land of Equestria. Upon entering this world, she was transformed into a pony. In a strange body and in a strange land, Chell was fortunate enough to be accepted by the ponies of Ponyville, and she lived out a new life contently among the ponies.

But that peace was not to last, for GLaDOS took a particular interest in the ponies of Equestria, and after two weeks of preparation, she launched a surprise attack and kidnapped 300 ponies to serve as test subjects, including Chell's friends and the princesses themselves. Once GLaDOS had them, she subjected them psychological torture. To save her friends, Chell made her way into the one place she hoped never to see again. In doing so, she freed the ponies, defeated GLaDOS in battle, and helped bring about the destruction of the facility. Although this made Chell a hero, she paid a terrible price in that brutal fight.

Beaten, battered, and traumatized, Chell spent months recovering from her wounds. After returning home from the hospital, all she wants is to once again live a normal life in Ponyville, but to do that, she must first heal from her wounds, both physical and psychological.

At the same time, GLaDOS herself has survived Aperture's destruction. With nothing left but herself, she vows to get back to testing. Though she faces an uphill climb, she is determined to see her facility rebuilt and the testing resume, and will stop at nothing to achieve this.

Has a TV Tropes page (will need to be updated after rewrite)

The works that this fanfiction is based on are properties of Hasbro and Valve. I would like to thank Pen Stroke for writing the original story and Flyer for his assistance and advice.

Please note, this is an unofficial sequel. I have received permission from Pen Stroke, but it is not canon to the original. I hope you enjoy it, but keep in mind that this is a fan work (of a fan work), and Pen Stroke holds the rights to the original story.

Commander Shepard remembers firing the crucible. She remembers she had to make an important choice. She remembers good friends, a lover, and plenty of loyal crewmen.

She just can't remember what her choice was. What the threat she was striving so hard to end was. Or what the faces of the most important people in her life look like.

She also has no idea how she wound up in the monster filled forest she's come to call home for the past eight months. Or how she picked up a snarky A.I. making its home in her omni-tool.

While he has returned from being absorbed into Unit-01, Shinji finds himself in an odd situation. Now, in a body that looks nothing like a human's and with a snarky roommate in his head, he has to deal with new powers and abilities while those around him shift.

And he thought that fighting Angels was weird...

This story is a sequel to The God Empress of Ponykind

One thousand years ago, Luna, Warmistress of Equestria and sister of Empress Celestia, fell to the powers of Chaos and plunged Equestria into a brutal civil war. The Traitors were defeated, but not before Luna made the ultimate sacrifice and was sealed away in the Immaterium with only the soul of a slain Primarch to keep her company. For a millennium she has been locked away, waiting for a chance to return to her home and her sister.

Now, she has been freed from the Immaterium, and as she takes her first steps in a new Equestria, one ruled by the powers of Harmony, only one question remains:

Does Equestria still need the services of a Warmistress?

Comments may contain spoilers. YOU HAVE BEEN WARNED!

Also Tropes. Please contribute.

Jason has been in Equestria for quite some time and has lived countless lives. Some have been short, others have been rather long. No matter the length, they all share one thing in common. They all end in fire and flames.

He has spent centuries wandering the countryside, gravitating towards events. When whispered words of Nightmare Moon's return reach his ears, his feet take him to Canterlot, where what he encounters leaves himself and many others more than intrigued.

An idea that sparked a story. Immortality is an often used plot device with a Human In Equestria story, and I wanted something different, something new, something... fresh. Thus, the concept of mimicking the phoenix came to life, and from it, this story.
