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

After receiving a strange book from Pinkie known as "The Bombinomicon", Twilight wakes up one morning to find that the mystical tome has been stolen, by...Twilight?

Things quickly unravel as RED Team's Tavish DeGroot (Demoman) and Spy find themselves not only trying to get back home, but also fighting for their lives as villains from the Team Fortress 2 universe combine forces with some of the most dangerous foes Equestria's ever seen!

Spike loses a bet to Snips and Snails. The consequence? Ask Scootaloo out on a date. But what starts off as a frivolous punishment for the baby dragon ends up becoming much more rewarding than he ever expected.

Ponies have done some crazy things for love, but Twilight Sparkle and Rainbow Dash have come up with the hair-brained scheme to top them all. Based on the success Applejack had with her ex-automaton husband, they decide to wake up the robots Nil and Null. They don't see the harm in having the machines masquerade as their special someponies for the day. Surely, it won't have any lasting consequences.

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.

When Sweetie Belle got zapped during the Zap Apple Harvest, no one thought much of the filly's light electrocution. However, the zapping has given her a most unusual ability... the ability to change the color of objects, temporarily, into the colors of the rainbow. This is surprising to the little filly, as she has yet to achieve mastery of most magical arts beyond a novice.

Naturally, her adventurous streak gives her an idea. Sweetie Belle will become a superhero. She is the vibrant guardian, the watcher of the palette. She is...

Zapfilly.

Silence. The golden rule is silence. Silence, and obediance.

For years, you have trained as a royal guard. Now, thanks to the fortuitous return of Shining Armour, your old-time friend and Captain, you are promoted to guarding Celestia personally. What follows, though, is the discovery of a personal side to the Sun Princess that you could never have imagined, not even in your most vivid dreams.

I have always been alone in this forest. I have always feasted in this forest. I call this forest home and those ponies that travel through it are my prey. I devour all those who fear me, all who come to face me. They fear me for I am Fear incarnate. But now...I have met one who does not fear...and I am unsure of what do with her...

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?

(This is a bit of an experiment based on the worldbuilding concepts presented in AnonAuthor's Xenophilia [[NSFW] - caveat lector!], which intrigued me enough to want to take a closer look. It's likely you'll be very confused by this unless you read at least some of Xenophilia. Updates will appear as and when an idea pops into my head for a thing to add. And fair warning, some of this might come across very dry and dusty. Thank you academia! And thank you AnonAuthor for letting me have a go, and both AnonAuthor and AnonponyDASHIE for all the collab work they're doing. I'll make up for the dust by tossing in the odd piece of art now and then.)
