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.

A man who has been blind his entire life has somehow ended up in Equestria. Though, something is. . . off about him. The ponies seem slightly less afraid of him due to his handicap, but looks can be deceiving.

(I'm not the best writer out there, no not even close. Also this is just an experiment, lets see where it goes. Criticism is welcome, inspiration and encouragement is welcome also.)

It's a rainy day in Ponyville, and Button Mash is spending it like he spends any other day - gaming. But Babs Seed needs a place to crash while she waits out the rainstorm, and his basement is as warm as anywhere. In the process of making herself at home, Babs gets cozy - much to Button's discomfort.

It was only natural that introspection would come in the wake of something as monumental as a royal wedding. With the festivities of Shining Armor's betrothal long since past, Twilight has come to realize that there exists a tremendous gap in her studies of friendship, that being that she doesn't really have any stallion friends. That's likely because pursuing platonic relations with the opposite gender is rather difficult when there's a growing desire in her heart for something deeper than her friends can provide.

After an afternoon of disturbed study time and unexpected dental catastrophe, the last thing Twilight would have expected was for opportunity to come knocking in the form of a quiet stallion reading in her library. Enraptured by the chance to expand her education, Twilight bumbles into the newcomer's life without the faintest notion of the depth of the pony's loss. Though her faith in friendship is strong, it will take more than her magic to undo the scars of his past, and keep a heart once filled with wonder from succumbing to the power of doubt.

Set after the events of the season three pilot and before Twilight is crowned princess.

After they set off to meet with Zecora for a spot of tea and a catch up, Fluttershy and her friends find themselves attacked by a large pack of Timberwolves causing Fluttershy to become separated from the group. After becoming wounded and lost deep within an unfamiliar part of the forest and with the wolves on her tail, she is rescued from certain death by the most unusual creature.

When Twilight is attacked and nearly killed by a madpony claiming to be her brother, she, the Princesses, and the rest of the Elements of Harmony find themselves saddled with a shellshocked soldier who would like nothing less than to end her life. While they help him adjust to normal life, he makes his story known - and what he claims causes them no end of worry.

A Spartan of the UNSC falls into Equestria and has various shenanigans in the land. First chapters revolve around how he meets the royalty, the mane six, and the new world in general.

The Lone Wanderer has been known as the man who shouldered the nightmares of every man, woman and child in the wasteland, so that they may live. But when the Wanderer was once again abducted by aliens, he found himself falling, quite literally, into a whole new wonderous world, untouched by the horrors of nuclear devastation.

He has been facing other people's nightmares constantly for almost a decade, it was high time he was allowed to wake up.

Meanwhile, the ponies of Equestria are baffled by a strange object that fell from the sky.

Fallout/FIM crossover. HiE. T for violence and some language.

What sort of ruler will she become? And will she manage to protect her own little ponies?
