He had done it. The giant demon that had masterminded the invasion of Earth was dead, and Hell was in shambles. All that was left was to backtrack through Hell and go home to help rebuild the ruined planet...
But of course, it's never that easy. Just one wrong turn, and he arrives from Hell itself into a land filled with pastel-colored ponies. How will the man who had just destroyed Hell adjust to the sudden peacefulness after all he had been through? And is Hell really destroyed for good?

Inspiration is Rarity's Element, and Sweetie Belle her greatest achievement. But the filly has questions, ones that Rarity might not be able to answer on her own. What makes a pony? How can somepony know if they really are alive? Are they alive if they laugh and cry? Are they alive if they think, if they make mistakes and have ideas?

If Sweetie Belle is nothing more than a collection of wires, is she truly alive?

This story is a sequel to Mission: Improbable

A few weeks after the Spy returned from his extended stay in Equestria, the Medic found that he needed to have a few of those so-called "ponies" to... study. But with robots still attacking Mann Co., how can he find the time to acquire such a specimen?

By sending a scout ahead, of course.

It had been about a month since the changeling incident in Canterlot. Everypony is on edge, because stray changelings keep popping up here and there, trying to blend in with the population. Everyone worries that one of their closest friends, or even their family, could not be who they appear to be. But what happens when a pony isn't really that pony...

...but they're not a changeling, either?

Something sinister lies inside the Everfree Forest; something that even Nightmare Moon herself was terrified of while she walked the same earth.

And now, that entity is calling out, calling out to those with wishes seemingly too large to fulfill.

But none of them ever return.

A simple click of a button lands the famed Swedish gamer PewDiePie in the land of the ponies, and now he must face daunting challenges and horrid foes in order to save himself and the rest of Equestria. Will he do it? Can he?

Cover art was the best I could find. Sorry for the inaccuracies implied.

MY APOLOGIES FOR MY POOR SWEDISH. Yes, I used Google Translate, and yes I know it's not very good.

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.
