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.

When a Necromancer is hurled into the place between places then escapes to another world at the cost of his life it is not the end. Being a Necromancer he returns to life with ease, but is skirting the edges of consciousness, and unable to truly wake as a mysterious figure uses magic to put him on the back of a horse to carry him away into the night.

To make matters worse the phylactery he used to save his own life recreated him as a member of the dominant race with... some errors. His injuries are still present and he's now in a much smaller body with his magic drained to nothingness.

So now he's horribly injured, held captive by an unknown force, in an unfamiliar body, in an unfamiliar world and completely exhausted. He's had worse days. He just can't think of any off the top of his head. So familiar territory then, nothing to worry about.

(Thank you again Tulip for the amazing piece of artwork.)

On Hiatus due to Life. Sorry.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

A young man lost in the hilly embrace of a mountain sleeps the night away under a knot of tree roots. When he wakes he will find himself thrust into a strange new environment, the Everfree Forest. With only his pack and his experience as a Boy Scout to aid him, he must survive, make sense of his surroundings and with some luck, ultimately find his way home. What does one do after wandering beyond the edge of the map? And better yet...

What if you are not alone?

I have been reading fan fiction here for a while and wanted to give something back.
My first fiction ever so constructive criticism is welcome. Fair warning, it takes a while for me to write a chapter so expect gaps between updates.

[Hiatus notice: As of 10/1/2022 this fiction is on hiatus so I may focus on other projects and items, will resume at a later date.]

Rated teen for strong language

Awesome cover art by Carnelian. Seriously, the guy has major skills with how fast he drew this up.

and of course ALL CHARACTERS / REFERENCES BELONG TO THEIR RESPECTIVE OWNERS. “MY LITTLE PONY FRIENDSHIP IS MAGIC” IS OWNED BY HASBRO

NO PROFIT WAS MADE IN THE CREATION / DISTRIBUTION PLEASE DONT SUE ME OR ANY PARTY THAT DISTRIBUTES THIS WORK (unless they try to sell it, then by all means go nuts)

While moving to her new home, Zecora find the strangest creature - a large, nigh-hairless talking monkey-thing. Seeing how it lacks basic knowledge on surviving in the wild (and that it's quite tall and probably good at manual labour) she decides to adopt it as her assistant. Hopefully, she won't come to regret her decision.

Have you ever woken up somewhere you don't recognize? I have, once before. This time was not all that different. Headache? Check. Dry mouth? Check. Upset stomach? Check. Hooves? Uhm, that one is new.

Hi, I'm Bruce and I'm 32. Currently, I'm in a light blue Earth Pony foal's body no one has ever seen before. The rest of Equestria thinks I'm 9 and something really traumatic happened to me. It doesn't help I swear like a sailor and I could really go for a smoke right about now. I just hope that the Everfree Forest, rampaging monstrosities, evil dark abominations against God and the Cutie Mark Crusaders don't kill me before I have just one last drag.

Oh, and ponies are hella creepy when you really think about it. Geez.

A little comedy side project. EDIT: HAHA Main project. More characters to be added if I get that far. Categories might be refined as I write. Entire thing is unplanned except vaguely. Don't Expect excessive cursing to be written out, just hinted at. Oh, and as the character is a 30-ish year old in the body of a 9 year old, sexual jokes might exists but sex itself will not occur.

Special thanks to user Momomojito for the awesome-tastic picture! First fanart, I'm so HAPPY. I've gotten more since then! I should collect it all here. Collected!

This story is a sequel to An Affliction of the Heart: Volume Two

Swarm is the first ever changeling/pony hybrid, child of Warden the pegasus, and Kuno the changeling.

What does life have in store for this unlikely trio?

Twists, for a start!

Young Nictis had one dream: to serve his hive by becoming an Infiltrator, the most vital and vaunted role a changeling could aspire to. To hide in plain sight among the other species, blending in, while gathering the vital emotional energies that fueled his people. Few were deemed worthy of the dangerous job. He was one of the few nymphs selected for training, in the hopes that one of them would develop the skills needed to be entrusted with such a treacherous task.

But when a training expedition ends in tragedy, Nictis finds himself thrust into the role not to serve his hive and people, but to preserve his own life. Separated from the hive, alone, he must put what little training he has to the test. He must blend in with the hive's greatest source of food, and its most dangerous enemy: the ponies of Equestria.

(This story takes place in the same continuity as Fragments, but stands on its own. Reading that story isn't necessary for this one.)

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

Other tags: historical, mind control, Clarke's 3rd Law, excessive use of high energy physics, before they were famous.

A Soot-Covered World, book 1.

Diablo Crossover.

The Archangel of Justice destroyed the Worldstone to spare Humanity the corruption Baal infected it with. The force of its death knell shatters Mount Arreat and sends Tyrael hurtling across the endless planes of reality. He falls upon a world untouched by Angel or Demon, far from the sight of the High Heavens. So far, in fact, that he fears he will not be reborn from the Crystal Arch.

Wounded and near death, hope appears in the form of two strange creatures bearing the power of night and day.

Tyrael now faces a time of recovery as his power slowly heals within a body fashioned for him by his saviours. Justice Incarnate tastes for the first time the life of a mortal, and it is a strange, confusing experience .He has been left in the care of one Twilight Sparkle to learn of this world.

After all, where better to find peace and harmony than Ponyville?
