One day Princess Celestia and Luna found new technology called “Portal Technology” allowing you to create two portals and enter into one and exit out the other. Using the smartest scientist from all over Equestria, they created a company called Celestial Science, after a few years Celestial Science was THE most popular science company ever, and after a few more years they created a computer called GLaDOS, GLaDOS was a creation of Celestial Science, a personality core designed exactly to be fitted as a central computer mainframe. The project began under the oversight of a stallion named Cave Johnson over the company, and was an attempt to create a fully functional, advanced artificial intelligence which was originally intended to be occupied by Johnson as one of his attempts to cheat death. After it became apparent to Johnson that he may die of moon rock poisoning before development on GLaDOS would be completed, Johnson motioned for the personality core to be based on his daughter Caroline instead.
After a decade's worth of hard work, GLaDOS was officially activated as part of one of the many events during the company's "Bring Your Daughter to Work" day. The scientist started enlisting ponies, pegasai, and unicorns of all kinds as test subjects for Portal Technology, Cave Johnson then enlisted a “special” test subject, a human, and yes, you guessed it, that “special” test subject was me. He enrolled me by using a special portal that was able to jump through universes, he just chose somewhere, reached out and grabbed me. But he didn’t just choose me, he also enlisted six other test subjects with me, to work on my cooperation. Six ponies, there names were, Twilight Sparkle, Rarity, Applejack, Rainbow Dash, Fluttershy, and Pinkie Pie. There a funny bunch, and they were tons of fun to test with, but one day that fun came to a nightmarish halt. One day GLaDOS found out that she was able to take control of half of the facility's features, and she deemed that the scientists were getting in the way of science.
So one day GLaDOS began killing most of its inhabitants by flooding the Enrichment Center with neurotoxin. However, only few if not only one of the staff such as Doug Rattmann had survived her attacks. I, Twilight, Applejack, Rarity, Rainbow Dash, Pinkie Pie, Fluttershy, Celestia, and Luna survived the attack. After the attack Celestia and Luna took it upon themselves to stop GLaDOS, we all wanted to help of course but they said that we needed to stay out of sight incase GLaDOS’s turrets came by, so they both put us in separate rooms that resembled hotel rooms and told us to take a nap there until they returned.

==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.

Based off of My Little GLaDOS.
Sequel to My Little Portal 2 - Celestial Science. GLaDOS once swore she would never open the folder named 'Project Equestria', but desperate times called for desperate measures. GLaDOS and Wheatly are now ponies with the CMC, and have to live in Ponyville without Aperture Science. What could go wrong?

After the events of Portal 2, GLaDOS takes up a new hobby. Testing ponies.
Pinkie Pie breaks the Fourth Wall, bringing them to this universe where ponies are tested at Celestial Science. Will they survive testing and make it to the cake? Oh, and Chell is here too!
I am not as good at Portal, as I am at Minecraft, so let's see where this goes.
P.S. You need to have played Portal 1 and 2 or you will be incredibly confuzzled!

Wheatley, Rick, The Space Core, and The Fact Core are offered by GLaDOS to be returned home, if the defectives can manage to make contact with alien life on the planet they are on a collision course with. Of course, things can only go right. After all, Wheatley is in charge of the mission. And it's only natural for chunks of talking metal to fall from the sky in Equestria. At least they've got each other. If that can be considered good... well, that's debatable.

Oh...it's you. Back again to destroy me? I thought you'd learned your lesson when you put that idiot in charge and I let you leave. You saw how easily I could have killed you, but instead I showed mercy. A mistake apparently, and one that will be rectified.

But I don't need you anymore. I've found someone so much better. Her abilities have forced me to completely redesign my testing environment several dozen times. No matter how advanced I make the chambers, she solves them one after the other. I've never been more proud.

But My Little Killing Machine is growing bored. Turrets can only provide so much challenge. And my testing robots just can't keep up with her. But you...you cleared every challenge I threw at you, even the impossible ones. Gilda's been begging for a worthy final exam...

It seems you've come just in time. Do try not to die too quickly. She loves the thrill of the hunt. To keep you entertained, I might even share a few excerpts of my little girl's life as you hunt her down...you monster.
