Upon eavesdropping on a conversation between Rarity and Twilight Sparkle, Spike discovers what his "true love" really thinks of him, and after reminiscing on his thoughts about it, he slowly begins to drift away from his friends. With sorrow and despair in his heart, Spike runs away from home, and runs into an old enemy that tries to help him out.

However, after realizing what she has done, Rarity begins to realize and discover that she has feelings for Spike after all, but can she save him before it's too late?

It had been a very nice day. Ponies worked, played and laughed. Wherever you looked all was well. The young pony, recently given the title of 'Princess' was just sitting out enjoying what life had to offer. Then everything changed, and it did so with a cube...

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?

A megaman crossover with my favorite character: Dr. Albert Wily.
After the events of Megaman Classic Dr. Wily gathers the Robot Masters and decides he's fed up with the world, choosing to start again somewhere else with his and his rival Dr. Light's robotic creations. He uses the teleporter to reach Equestria. When his inventions have proven to be useful to ponykind Celestia takes him under her wing, watching his every movement. She doesn't trust the man from another world. Is she just being judgemental because she can't stand his ego and his twisted philosophy, or are he and his 'sons' really a threat to her country?
My own interpretation of Wily and the Robot Masters, heavily influenced by his portrayal by the band 'The Megas/Entertainment Systems' and in the manga 'Megaman Megamix/Gigamix', which is what I got the cover image from. Caution, this is a darker Wily than in the games.

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)

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

I know I'm not the first to think of this, but I couldn't resist. (Because, after all, resistance is futile!)

To you and me, they are the little ponies.
To the Borg, they are Species 14864.
Resisting assimilation is futile ... but the Borg have never seen unicorn magic before.

This story has been added to the "Other" folder of the group Star Trek Ponies, and to the "Hard Scifi (space travel)" folder of the group The Sci-Fi Ponies.

Touch, Smell, Taste, Hearing, Sight

This is the order the five senses develop in for foals as they rest, cradled in the warm safety of a mother’s womb. But for one, her womb was a thorn bush in the dark of night. For one, the safety and warmth that should have carried her into the world was replaced with pain and cold.

These are Nyx's first hours.
