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.

A long forgotten and believed dead enemy, now more powerful than ever, is returning to Earth. Lead by the circumstances, its protector sends him to a distant land. Weak and with an unfamiliar body, the proud warrior will search for a way to retrieve his old life back, but not without meeting some unique characters on the way.

Twilight Sparkle is summoned to settle a legal matter involving The Great and Powerful Trixie... What in Equestria did she do now?

Rainbow Dash finally did it! A sonic rainboom on command! Except she also managed to break every window in Applejack's farmhouse in the process. Now she has to pay for each one, and with her wages from managing the weather not nearly enough to cover the damage, she has to work on Applejack's farm for two whole weeks!
Talk about cruel and unusual punishment. Still, maybe it wouldn't be all bad. At least she would get to hang out with her friend AJ right? Wrong.

Sequel: http://www.fimfiction.net/story/4620/Breaking-Barriers

Instead of being killed in the cold Antarctic by Dr. Manhattan, Rorschach finds himself rematerialized in a strange new, pony filled world. He finds himself drawn into the lives of the ponies of Ponyville but some ponies fear that this sociopath will bring danger and darkness to an otherwise peaceful existence. Will the mane 6 help Walter Kovac find peace within himself or will he bring them all down with him in his cold views of reality and existence?

The legends told of their return.

For over a decade Equestria has been beset by the dragons. Every year more villages vanish in flames, and the lonely cities stand as our last redoubt. Winter has gripped the world, and our hope is fading.

But the legends tell of another, a light in the darkness. The Dragonborn, a mythic warrior reborn with the power of the Voice, the only one who can stand against the dragons.

But when she appeared, she was not what we were expecting...

Sly Clop is a laid back slacker who runs one of Ponyville's only porn shops on Soresaddle Street. He is a regular customer of Hard Cider's "gentlecolt's club", the Knife and Apple, where he regularly shoots the breeze with Rainbow Dash, who's seen better days.

One day, his only employee quits, and he's forced to hire a new one, starting a new awkward relationship with Lyra, who needs cash. What follows is a lighthearted fic with dark undertones that I hope you'll enjoy.

And if I haven't convinced you enough by this point, no, this not a clopfic.
