Set in the TwistedSpectrum's Five Score, Divided by Four setting. If you haven't read it yet I'd recommend giving it a look. Very interesting concept. Though the whole time I was reading it I kept wondering where the Princesses were. He said he didn't plan on using them so I decided I'd have a go at a side-story in his cool universe. XD

Curious about Five Score? Come check out the story that inspired dozens of side fics and been enjoyed by bronies for years!

Original Synopsis Even though MLP:FiM ended a few years ago, my friends and I still loved the show. Stories, merch, fan art, I loved it all. Things started to get a weird though when I found myself with a cutie mark appearing on my leg. Humans aren't supposed to get cutie marks, so where the heck did this come from? And what's going on with my hair?

More Detailed Synopsis: Five Score is an action/adventure story of the human-to-pony transformation genre. It’s unique from most transformation stories because the transformation itself is not really the point of the story. It’s the inciting incident that raises countless challenges that must be resolved. They are on earth, as a pony, and need to fix this before things get worse. Think about yourself in their hooves for a moment. How are you supposed to change back or even figure out what caused it in the first place? How are you supposed to get food or do anything on Earth without being spotted by humans? If you are spotted or captured, how would you escape? How does one even open a door with hooves!? Did anyone else on Earth get changed as well? How could you get the word out to the other ponies who are themselves hiding? Is it worth risking travel across the country to reach the others? Which of your friends would you trust to help you deal with this? And why did you turn into this particular pony? Surely it wasn’t random chance, right?

These challenges are the tip of the iceberg in this full length adventure novel There’s a lot of humor, many tense scenes, and hell maybe even a war.

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.

==Originally written spring 2011== Equestria Daily Post==
GLaDOS is free of Chell, free to continue testing, when she discovers a portal gun Wheatley tried to repair with duct tape. When the portal gun catastrophically fails, the enrichment center, GLaDOS, and Chell are literally dropped in the middle of Equestria. The mute test subject soon finds the world of ponies far more welcoming than the human world. But GLaDOS sees possibilities. Let the testing begin... for science.

After GLaDOS is uploaded into a potato battery, Wheatley humiliates the AI even further by uploading her into a project that was abandoned by Aperture a long time ago. In the blink of an eye, she finds herself in a deformed body of flesh and bone that resembles an equine, and is just as powerless as one too. It comes with all of its needs and bodily functions as well. To make matters worse, she's trapped in a land full of insufferable creatures that just want to make 'friends.' Will GLaDOS' cold, sadistic sense of humor and morals get the better of the ponies? Or will they peel away the once artificial being's metallic shell and find that there's a softer side? Probably not, but it's worth a try.

This story is a sequel to A [Fe]Male Perspective of Equestria

Six months. A lot can change in such a short time. Like going from a human guy on Earth to a female alicorn in Equestria. I may be mostly used to my new body, but I still haven't found my place here. Being an alicorn has only made things worse... everyone expects great things from me, and too many ponies look up to me for no other reason than because of what I am. Hopefully I can figure this out sooner rather than later...

Looking to explore the concept of how a blank-flank alicorn would fit into Equestria... without the stupid silly charisma, insane magical ability, or supersonic flight capacity. I know alicorn OCs have some stigma to them that instantly labels them as a Mary/Gary Stu, but I plan to avoid all of that silliness.

A sequel to A [Fe]Male Perspective of Equestria (can't link directly due to NSFW content), now with much less insanity, but with the same amount of comedy. Reading this is not required, although it is recommended. If sex is not your thing, all three chapters marked with (***) are skippable without losing any story content. The writing is crude/humorous/unedited, please be aware of that.

NOTE - Tags. While the protagonist was human in the previous story, I am leaving the [Human] tag off. This is not a Human-In-Equestria story, please do not add it to any Human-related groups.

Explicit sexual scenes are being left out of this story submission. When I get to them, there will be a note saying to go to its prior story, as I will be posting the scenes on there.

Princess Celestia's daughter Scootaloo was foal napped, driven mad Celestia wiped her memory of Scootaloo, but when she meets her again Scootaloo remembers Celestia immediately. With the help of Scootaloo's aunt Princess Luna will they ever be able to live in harmony together again.

Princess Celestia has called Twilight Sparkle and her friend Rainbow Dash to meet her in at the castle. Unsure of why they are the only ones called to there they make haste for Canterlot. What must she tell them that the rest of their friends don't get to hear? How might this change their outlook on their ways of life? And how will they react when they hear the knews? Only one way to find out.

Please read and comment. I do not own My little Pony characters, that credit belongs to Lauren Faust and her crew.
Rated Teen to be safe.
