Commander James Bond was one of MI6's top operatives. Having succeeded in countless missions and bringing down international terrorists such as Le Chiffre and Dominic Greene, Bond is sent to Istanbul to retrieve a hard drive containing the names of every agent involved in undercover affairs. The hard drive in question has fallen into enemy hands, and it's his job to get it back.

After disastrous events in Istanbul during the mission, James finds himself in an unfamiliar land, and soon becomes entangled in a tale of international espionage.

Only one man can protect Equestria and its princesses in this new time of crisis, and his name's Bond.

James Bond.

A sequel has been published: An Equestrian Princess in London.

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...

Years ago, in Equestria, there was a combat racing league known as the WipEout Anti-Gravity Racing League. After some issues with corruption in the sport's officials, though, Princess Celestia was forced to shut down the entire league. However, at Luna's urging, she's bringing it back - just in time for Twilight and her friends to get involved.

This story takes place approximately 15-20 years in the future from the current FiM universe, and borrows canon and concepts from WipEout 2048 and WipEout HD/Fury. Yes I'm aware that those two games are, in the WipEout universe, on the opposite ends of the in-universe chronology. I apologize in advance to die-hard WipEout fans if I muck up some canon, as the only games I've played are Pure, Pulse, HD/Fury, and 2048, and my only other knowledge of the in-universe canon is a "WipEout canon in 10 minutes" video from YouTube.

One night, an amazing display lit up the sky over Ponyville. A comet, brighter than any in living memory, was making its way through the sea of stars. The residents of the town gathered en masse to witness the spectacle. As was the tradition for such an occasion, many ponies made a wish on the celestial body, hoping that maybe, just maybe, some of them might come true...

When the Elements of Harmony defeated Discord, they did their job too well, and completely undid all of the things Discord directly did...

... Like send a subcontinent from earth into a pocket dimension so he could focus properly on his toys. And now Equestria has appeared on Earth.

Yet, neither side was completely ignorant of the other. On Earth, there was the show "My Little Pony: Friendship is Magic" and in Equestria there was the ever popular movie serial "The Dark World: Technology is Courage" which was a favorite of colts everywhere as well as the "Pumans".

And now both sides learn through an event that the other is real. Come join us as we watch as both sides learn to work and live together. And as they find out that events on their respective fiction was not as nice as it seemed as we widen the lenses of the view points...

Johnny is a typical Southern boy from a small town in Tennessee who just happens to enjoy My Little Pony, but hates a certain orange workhorse for her stereotypical behavior. Soon, he finds himself hiding out in an abandoned barn waiting out a storm only to wake up in Sweet Apple Acres and in front of Applejack. Johnny doesn't see eye to eye with her, but when Applebloom and her friends are stolen away from the farm during the middle of the night, he finds out there is more to this pony than meets the eye. Can the two form a fast friendship in their effort to locate the CMC, or will they have to dig a few graves for three little fillies?
