"We work in the dark to serve the light. We are Assassins."

These words mark the very existence of the Brotherhood and their mission to preserve the freedom of man from the Templar Order.

The Mane Six, having arrived in France after a mishap with the Element of Magic, are rescued by a member of the Assassin Order. Who are the Assassins and Templars? And why do they have such interest in the Element?

After successfully completing another mercenary mission, Deadpool feels that he is living an unfulfilled life. As he flips through his television, he discovers a show called My Little Pony: Friendship is Magic. Deadpool becomes instantly obsessed, and not long after, he starts comparing and contrasting the world he lives in today to the world of Equestria. He suddenly concludes to himself that Equestria would be a better place to live in...

After tiring of Twilight's hostile attitude, Discord decides to "help" the Elements of Harmony by bringing in an alternate version of each of them. These duplicates from various worlds aren't told anything about each other, which is good. The last thing Equestria needs is these monsters working together.

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)

Two worlds that were never meant to meet. Two ancient and powerful artifacts, separated by dimensions. Two princesses who need to defend their kingdom from an ancient evil thought to be sealed away.

One man, thrown in between it all by the cruel hand of fate.

Vader was soon the scourge of the Jedi, continuing the Great Jedi Purge by slaughtering all remaining Jedi.

With his connections to the Galactic Empire severed, Vader must find a way out the land known as Equestria, inhabited by the strange creatures known as ponies. That, or he could take it over.
