Once upon a time, on the not-so-magical planet Earth, there was a US Marine who signed up to defend his country. He was assigned to a fire team, the fire team assigned to a squad and the squad assigned to a platoon. Together they defended the area surrounding a Forward Operating Base in Afghanistan from insurgents. If only it were that simple.

When lone Marine is transported to Equestria he finds a post-apocalyptic wasteland. With no orders, no resupply and seemingly no hope of return, he sets out to find what brought him here, and why.

Strong Language Warning: He swears like a Marine.

They take… really long bubble baths.

An indirect sequel to “My Little Staring Contest: Alicorns can stare for a very long time.”

Rainy weather and a looming deadline drive Twilight Sparkle up the walls and Spike out of the tree. Only Pinkie Pie can save the day, by introducing the reluctant librarian to an unexpected new hobby. Astoundingly, sex does not ensue.

This story is a sequel to Miller

In the underworld of Equestria, where lowlifes lurk and crime runs rampant, one pony is whispered about with fear and hate. Not many know where he came from or why he (accidentally) left a trail of destruction through the criminal ranks. In fact, Vinyl and Octavia were his only confidants. Now the mysterious visitor is back, and he's, well... not a he anymore.

An ancient enemy has escaped their bonds and threatens to destroy the entire world in a black night of chaos and uncreation. What Equestria needs is Twilight Sparkle and the Elements of Harmony.

Unfortunately, what Equestria is getting is Princess Luna's rather dangerous-sounding 'Doom Patrol'.

Luna! Derpy! Princess Erroria! A weird-looking cyclops! They and the rest of the animation error ponies must race to save Equestria from the doom that awaits. But it's a task they can't possibly hope to achieve.

Because their enemy is... Nobody?

[NOTE: This story is very loosely inspired by Grant Morrison's 'Doom Patrol' comics from the 80s; absolutely no knowledge of it is needed to enjoy this, so don't get scared off!]

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there. She does not know the language, the geography or any of the rules of this new time. She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.

War threatens the nations, a Nightmare stalks the shadows, and Rainbow Dash's arrival has turned her into a wild card in a deadly game that pits the law on both sides of a broken Equestria against a mysterious criminal figure, Max Cash. Yet the stakes are higher than anyone knows, for in her research Twilight Sparkle discovered a dark secret about the Elements, something that will shake the foundations of the world.

Trixie appears once more in Ponyville, but something is...off...about her. She isn't speaking in third person. She is convinced that she is supposed to be the Element of Magic, that Celestia is supposed to be the Tyrant Sun, that Luna is supposed to rule as Equestria's monarch - and that Twilight is supposed to be a wanted criminal. Has she gone insane? Or is something bigger beginning - with consequences that Trixie, Twilight, and two entire worlds, can only guess at?

The long-awaited Crisis on Two Equestrias begins at last!

Little does Luna know that another force is in Ponyville, looking for revenge. And it might just settle for vengeance by proximity...
