So here I'm stuck in Equestria, in the form of Mewtwo from Pokemon, FUN!
What's not so 'fun' is that my appearance is frightening to most ponies. It doesn't help that I can only communicate by projecting my thoughts into the minds of others. Now I need to find some way to convince the Princesses that I don't want to harm anypony, and that there's something bigger is happening.

Twilight Sparkle wakes up one morning to a harsh dose of unreality. She is stranded, without her friends, on an island which matches no known locale on Equestria. Surrounded and harried on all sides by the alien and the dangerous, she will find her mettle sorely tested, and find perhaps that the best friends you will ever have in your life are the ones you make when your back is to the wall...

Thanks to CedricBale and noobie56xx for tracking down the name of the artist so I could give them credit.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

Princess Luna still feels alone, nineteen years after her return to Equestria . But when she finds a friend in an online game, everything seems better. She can be herself without worrying about what others think, and she can finally talk to another pony, even if he never knows who she really is.

Celestia is worried about her sister, especially right now. Upcoming peace talks with a powerful new nation mean that all the Princesses need to be completely ready. With her Luna so absorbed in a fantasy world, she wonders how she'll make it through the harrowing weeks to come.

Button Mash feels like a failure. He's still living at home, he still can't find work that can use his degree from the university, and he still feels alone. His friends are getting married, starting families, and thriving in their careers. On the plus side, he plays games regularly, and his best friend is a mare, even if she doesn't know his name. He hopes that his upcoming vacation to Canterlot might help his mindset.

But, unbeknownst to all of them, a sinister web within a dark plot threatens to ensnare Equestria... And Luna may be the only one able to stop it.

She may face it alone, or maybe she'll have some help from her knight in faded armor...

Follows canon up to about season 4 or so. I'm not sure when everything went off the rails, but it was originally as true as possible when initially written.

David Carrian can't help but be attached to his amazing, very expensive computer. As such, when a virus sneaks onto his system without his knowing, he puts all of his focus and knowledge into removing the threat that is screwing with his memory and CPU.

But he hears something coming from his headphones. A quiet, almost unnoticeable voice cries out from behind the computer screen. On one hand, knowing that the virus is playing such sickening sound effects drives him harder to fix the problem. On the other however, he stops to think after he finally makes out the words said to him...

This tale follows heavily on the Slice-of-Life and drama side of things, but sways towards adventure halfway through the story. As of Chapter 13 (treehouse.exe V1.31), we have not reached that point yet.

Episodes beyond season three episode two are ignored.

Fantastic, I finally get to visit my favorite cast of awesome talking ponies to have one small thing keeping me from enjoying it to its fullest. I CAN"T FREAKING INTERACT WITH ANYTHING. I guess being a ghost in Equestria isn't the worst thing that could have happened, at least I can shadow my favorite ponies and see what going on in their lives. Heh, I guess I've become the ultimate stalker, I do miss having someone to talk to that wasn't me, myself or I though.

*^*^*
Set before the events of season three.

Rated teen for now for safety, rating may change later on based on where the story goes. Characters will be added later if they get added to the story.

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.

For the longest time, Epona has served as the loyal mount of Link, hero of Hyrule. But one day, she finds out that she's actually from a world inhabited by intelligent, colorful equines. And not only that: Her daughter is one of the six main heroes from that world. But that is only the beginning.

When the worlds of Equestria and Hyrule get into contact after a millennium, lots of hidden conspiracies are revealed. Evil fiends from a time long forgotten emerge and some ponies begin to understand their powers as sages. But the one important question will be: What will Epona choose? Her friends from Hyrule? Or her family from Equestria?

It's late. So late, in fact, that it's early. The clock in the room reads well past one in the morning. There's also a storm hammering against this girl's home, trying to lull her to sleep. Stubbornly, she remains awake, drawing, surfing the internet, and basically procrastinating another night away.

So, what is it that makes this night any different from another one that she has lived through? What strange occurrence occurs that makes it stand out? That changes her life forever? That changes the course of- Oh you get the idea.

Have a look through "A Twilight Landing" and find out. Follow Twilight through her journey on Earth, her quest to return home, and the people that help her along the way.
