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

When a mishap causes two para-dimensional weapons to colide with one another, RED Team's Pyro is sent flying from the Team Fortress 2 universe into the alternate universe of My Little Pony, where he is almost instantly discovered by Lyra, who shelters him in her home.

Having him hidden in her small townhouse isn't easy; keeping him from setting things on fire, teaching him that not every cart that passes by is cause for alarm, and that blue ponies are not something to be suspicious of.

However, with Nightmare Night soon approaching, Princess Luna feels that there may be something more sinister riding on the coat tails of Pyro's grand entrance; the first human to ever set foot in Equestria some thousand years ago...

The wedding was a disaster, but the changelings were defeated. The only real price paid was a mare's trust in her friends and family. Now she will seek out a new path in life, teaming up with an exile and a music loving DJ, the group will forge a new destiny in life.

I know I'm not the first to think of this, but I couldn't resist. (Because, after all, resistance is futile!)

To you and me, they are the little ponies.
To the Borg, they are Species 14864.
Resisting assimilation is futile ... but the Borg have never seen unicorn magic before.

Sometimes, stories have a way of coming to live in the strangest of ways. One night, Discord got a little bored and decided to stop by Pinkie's to rid himself of it. Unfortunately, a series of events is inadvertently set in motion. Something that even he couldn't have seen coming.

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.
Also has a TvTropes page: Split Second Tropes.

Young Dinky Hooves has been taking magic lessons from Princess Twilight, and is now at the stage of learning teleportation. To help, Twilight gives her a stone that will help with performing the spell. However, the stone has some strange properties, as Derpy figures out. What horrors await her with unicorn magic in her command?

You all know what I'm referencing with this.

After years of shame and ridicule, archaeologist and explorer Lyra Heartstrings stumbles across a discovery that validates all her theories and ideas in one fell swoop. Along with her best friend, Bon Bon, and her old classmate Cadance, they find themselves faced with a mystery and marvel that may change everything.

Following the next greatest lead found in the database of an ancient race, another international team is formed. Led by Doctors Carter and Jackson, they strike out to explore another network of Stargates discovered in a galaxy on the edge of the local cluster. In the process, their findings will cause them to question much of what they thought they knew.

The adventures continue and unlikely allies will face dangers new and old as the Legacy of the Ancients continue to unravel in the latest chapter of the universe.

Now with a Russian reading by SviMik

When a portable teleportation device is created. Twilight soon discovers that she's doomed her friends to death in three days! Now it's up to each of the Mane 6 to make their peace, and for Rarity to help Rainbow Dash seduce one very pretty dentist.

Yeah, this follows the TF2 thing pretty closely for the Rarity/Dash parts. It's such a good structure that I couldn't help but maintain it. This is the cheesiest thing I have ever written, and I am so very sorry.

(Based on Expiration Date)

Twilight asks Sunset to help her out with an experiment of hers.

Twilight Sparkle has spent months researching chaos magic, developing a new spell to unlock magic nopony has ever experienced before. But when something goes wrong with casting, Twilight finds herself turned into a Draconequus and unable to control her new chaos magic. If she ever wants to be a pony again, there is only one who can help her learn to control her new magic.

Of course, learning from Discord was never going to be simple. And after a while, being a draconequus doesn't seem so bad anyway....
