In the magical land of Equestria, two alicorn sisters raise the Sun and the Moon every day to give the world a night and day cycle, basic for the survival of life. There are also two alicorns who rule over two very core aspects of life and harmony itself. Those are Love and Friendship. While not as ancient as the two sisters, all princesses are essential to the world's balance.
This balance is also sustained by the hard-working ponies, who make the seasons change and manage the weather to fit their needs, so everypony has enough food and water, and every animal is also attended to assure that any of them are caught in the changes of seasons.

But what about the planet itself? What about Mother Nature?
This is the question that Gaia asks when she arrives to this foreign world. After so much work her son persuaded her to take a long vacation in Equestria, saying that she needed one and assuring her that he would be in charge now, and she must take a break. But what can a several billion-year old alicorn possibly do to pass her time in this land?

Have you ever woken up somewhere you don't recognize? I have, once before. This time was not all that different. Headache? Check. Dry mouth? Check. Upset stomach? Check. Hooves? Uhm, that one is new.

Hi, I'm Bruce and I'm 32. Currently, I'm in a light blue Earth Pony foal's body no one has ever seen before. The rest of Equestria thinks I'm 9 and something really traumatic happened to me. It doesn't help I swear like a sailor and I could really go for a smoke right about now. I just hope that the Everfree Forest, rampaging monstrosities, evil dark abominations against God and the Cutie Mark Crusaders don't kill me before I have just one last drag.

Oh, and ponies are hella creepy when you really think about it. Geez.

A little comedy side project. EDIT: HAHA Main project. More characters to be added if I get that far. Categories might be refined as I write. Entire thing is unplanned except vaguely. Don't Expect excessive cursing to be written out, just hinted at. Oh, and as the character is a 30-ish year old in the body of a 9 year old, sexual jokes might exists but sex itself will not occur.

Special thanks to user Momomojito for the awesome-tastic picture! First fanart, I'm so HAPPY. I've gotten more since then! I should collect it all here. Collected!

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.

A freak lightning storm, strange lights, and an unassuming, yet mysterious stone obelisk. What do these things have to do with an average college student from North Tonawanda? At first, nothing. But when nineteen year-old Connor lets his curiosity get the better of him and lands in the center of a cosmic coincidence, he probably should have left well enough alone.

Now he finds himself stranded in an impossible world where magic is real, and "normal" takes on a whole new meaning. A world populated by sentient creatures calling themselves "ponies." A stranger in a strange land, Connor's yearning for answers and a way back to Earth will try both his patience and his sanity in the days following his arrival, even with the support of his new equine friends. But as he witnesses his life slowly spiral out of control, he will call into question his definition of home, humanity, destiny, and what it means to truly belong.

Rated Teen just in case for occasional swearing. This story takes place shortly after the end of Season 2, and the main character is from an Earth where MLP never existed (in order to preserve proper characterization). Or just assume he's never heard of it, that works too.

The title is not an Evangelion reference, I was just inspired by the wording scheme.

Not so long ago, Equestria barely defeated two almost unstoppable creatures known as humans, which they called the Second and the First. Almost five years later, another one has shown up. The military takes up arms, the princesses are stricken with fear, and the Elements of Harmony assemble, ready for battle. But 'the Third' has no idea what's going on, and only wants to know how he came to be here, and how to get back home. Good questions indeed...But will he ever get his answers? Or will his predecessors' legacy catch up to him first?

“Side story/prequel to Human by DannyJ, but can be read on its own. Contains spoilers.”

King Sombra’s dark influence was obliterated by the Crystal Heart, and the villain is well and truly dead. But when he attempts to steal the afterlife of an innocent victim, a human spirit is left hurtling towards Equestria, where this unfortunate soul is revived into the only vessel available: the reconstituted body of King Sombra himself.

Thus, a cheerfully oblivious alien is crammed into the form of the most evil and malicious being Equestria has ever known. Not that Shining Armor and Cadence know this, of course. As far as they are concerned, the King is back and he’s lost his fricking mind.

Spiders and Magic: Rise of Spider-Mane

While he has returned from being absorbed into Unit-01, Shinji finds himself in an odd situation. Now, in a body that looks nothing like a human's and with a snarky roommate in his head, he has to deal with new powers and abilities while those around him shift.

And he thought that fighting Angels was weird...

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?
