But she will have to put her blind trust in the hooves of one!
RD will also find that something is definitely off about this alien creature from another realm! What is it? Read to find out!

Update: The story line progresses somewhere after the Crystal Empire adventure adventure during season 3.

The human artist named Alice arrives in Equestria through somewhat odd means. Upon arrival she finds that she can't speak or read Equestrian. Because of this the girl has to find some other way to communicate, and if not through words then through emotion instead.

The Lone Wanderer has been known as the man who shouldered the nightmares of every man, woman and child in the wasteland, so that they may live. But when the Wanderer was once again abducted by aliens, he found himself falling, quite literally, into a whole new wonderous world, untouched by the horrors of nuclear devastation.

He has been facing other people's nightmares constantly for almost a decade, it was high time he was allowed to wake up.

Meanwhile, the ponies of Equestria are baffled by a strange object that fell from the sky.

Fallout/FIM crossover. HiE. T for violence and some language.

Now with a TVTropes page!

A fan of FiM wakes up in Equestria with only his boxers, a comforter, and a pillow. Is it a lucid dream or something more? He soon finds that things aren't as simple as expected and is thrown into a fight with his own sanity.

((The story is undergoing an overhaul. Please excuse the mess as I fail spectacularly at writing a story no one remembers to make myself feel better.))

Spartans never die, they're just missing in action. This has never been more true for Jorge-052 as, after activating the slipspace drive that was supposed to kill him, he is instead flung into a strange world where war is but a distant memory. Will the aging soldier be able to adapt to this new peaceful planet? Or will his only salvation be found in finding a way back to his own chaotic universe?

(It's my first time, so be gentle)

Twilight Sparkle wakes up one morning to a harsh dose of unreality. She is stranded, without her friends, on an island which matches no known locale on Equestria. Surrounded and harried on all sides by the alien and the dangerous, she will find her mettle sorely tested, and find perhaps that the best friends you will ever have in your life are the ones you make when your back is to the wall...

Thanks to CedricBale and noobie56xx for tracking down the name of the artist so I could give them credit.

A single changeling is cut off from the swarm during the attack on Canterlot. She's discovered by Vinyl Scratch and adopted as a pet. How will Wubsy the changeling, Vinyl, and Octavia cope when the town develops Changeling-phobia? Will Wubsy ever be able to prove her good intentions and stay with the mare she's grown so attached to? Rated Teen for off-page lesbian pony make-out session.

My bid to make "Wubsy" a more official part of the fannon. Check the source of the fic image to see the comic that started it all.

A gracious thank you to GarlicParsnip, Comma-Kazie, Chengar Qordath, JJ GingerHooves and Steel Resolve who proofread and co-authored the piece.

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

After the Pandorica falls into the exploding TARDIS, it throws The Doctor through the very last crack in time, a crack through which he can cross universes.No TARDIS, no screwdriver, a whole new pony body and a certain unhappy plasmavore that fell through with him, The Doctor begins to think that perhaps his plan was not as fool proof as it could have been.

How will The Doctor protect the highly confusing, sentient ponies from the plasmavore that seems to be harbouring an unholy grudge against all things Timelord? How will he adjust to his new body? And most importantly, why does he have a sudden craving for...pears.

Well, at least he still has his bow tie.
