And there came a day unlike any other-
When champions found themselves in Equestria united against a common threat.
On that day, they became heroes.
The invincible viking, Dovahkiin.
"What's a viking?" asked the dragonborn, turning to look at the the other champions.
Soma Cruz, Prince of Darkness.
"Hey, no- Just his incarnation/split soul/potential something or other," said Soma, arms thrown out to the side in a shrug. Even he was not sure what to call his situation.
The Dan, angriest hero there is.
"I have a last name you know- And who is talking anyway?" Dan had each of hands resting over both hips to look around.
Nathan Drake, fortune hunter and historian extraordinaire.
"I still don't know who Daring Do is supposed to be," Nate questioned with a raised eyebrow.
And Phoenix Wright, the first Avenger.
"That's copyright infringement! But we do need a team name..." Phoenix rubbed his chin in thought.
Humans, Assemble!
"You are not helping Pinkie Pie!"

(Interlude II is a mini guide if you want info and pics on the humans appearing in this story... So far.)

Part 1: Lyra's Pyro Predicament
Part 2: Twilight's Demoman Devastation
Part 3: King Sombra's Robotic Retaliation

King Sombra was soundly defeated by Princess Cadance and Shining Armor almost a year ago, and the Crystal Empire was free. Now, after a teleportation mishap, a lone Engineer from Gray Mann's massive robotic army has found itself in the mountains just on the border of the Empire with one task in mind: complete the experimental Lvl. 4 Teleporter and bring the robotic forces to Equestria...but what other dark forces might be laying dormant in those caves?

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.

"Hello there, and welcome to the world of Pokémon!" A voice echoed in the endless darkness. "My name is Twilight Sparkle, or as everypony seems to call me, the Pokémon Professor! This world, mainly Equestria apparently, is inhabited by interesting creatures called Pokémon!"

"Twilight?" Scootaloo whispered. "What are you doing in my dream?"

"Right, so you're name is Scootaloo! I knew that!" Twilight's voice echoed. "Your very own Pokémon adventure is about to unfold! All you need to do is wake up... Wake up... WAKE UP!"

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.

Thanks to BronyGamer for editing.
Terrible art by your's truly.

"The servers are the seven chaos. Chaos is power, power enriched by the heart. The controller exists to unify the chaos." -Tikal, Sonic Adventure

Chaos is regarded differently wherever you go, some places it is praised and in others it is hated. Some associate it with miracles, others associate it with destruction. When 7 emeralds, that contain this energy known as chaos, are accidentally warped into Equestria by a certain purple unicorn; conflict over the emeralds between Mobians and Equestrians ensues. But will they both be able to keep the emeralds out of the possession of the entities that hunger for this power known as chaos?

Harry Potter was a lonely boy who one day wished for a friend. Luna, trapped on the moon, wished for the same. And so their wishes are granted. How will the two deal with each other? And what about Nightmare Moon? Needless to say, their lives are going to change in both expected and unexpected ways...

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.

For the longest time, Epona has served as the loyal mount of Link, hero of Hyrule. But one day, she finds out that she's actually from a world inhabited by intelligent, colorful equines. And not only that: Her daughter is one of the six main heroes from that world. But that is only the beginning.

When the worlds of Equestria and Hyrule get into contact after a millennium, lots of hidden conspiracies are revealed. Evil fiends from a time long forgotten emerge and some ponies begin to understand their powers as sages. But the one important question will be: What will Epona choose? Her friends from Hyrule? Or her family from Equestria?

==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.
