This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

After the events of Project: Sunflower, Erin Olsen has returned to Ponyville, happy to pursue her studies in magic. After everything that happened the year before, she's looking forward to spending her days studying and having fun with her friends.

Meanwhile, on the newly discovered world of Harmony, humans and ponies work together to study this strange new world. However, their arrival causes something ancient to begin stirring. Something that may end up changing everything.

The year is 2806, and Humanity has long left the loving embrace of their planet. After defeating the fanatical Enlightened, a warmongering alien race who had come to destroy them, many thought that an era of peace and prosperity was to come.

But that was not the case. Earth was lost in the war, and Humanity was divided.

A galactic civil war is raging in the galaxy, and three notorious pirates seeking to leave that life depart on a voyage to find the long-lost homeworld of Humanity: Earth. But complications arise as their destination is far more colourful, and far more occupied than originally expected…

Follow the tale of the Cerberus Pirates, and their struggles on a foreign world with nothing but the technology on their persons and the wreck of their ship to work with. Striving to get back to Mother Earth, and doing whatever it takes to achieve that goal.

You know these stories where somebody suddenly wakes up with a creepy, unknown voice in their head? Well that's what's happening to me, except I'm that strange voice, and I'm not stuck in somebody, I'm stuck in somePONY.
How did I get here? And how will I ever find a way to go back without so much as a body to call my own?

Now with 100% more cover art thanks to the splendiferously awesome Exelzior! Go read his stuff instead of mine! Do it!

Rated teen for foul-mouthed protagonist. Expect bad words.

This story is a sequel to For Queen and Country

Twilight Sparkle always had a feeling that ponies were not alone in the universe. When he arrived in Equestria, she was proven right.

After he uncovered and subsequently overthrew a plot to kill the two princesses, they sent him back to his world. However, the curiosity of Princess Celestia was still unsatisfied. She had a glimpse of this other world through the mind of this one man, this agent of a service known as 'MI6', but wanted to know more. To this end, she resolved to send her former student there, in an effort to understand more of the human race and, perhaps, meet their mutual friend once again.

Who was this friend, you ask?

Bond. James Bond.

This story will involve some drama. Swearing, a little violence and action, but not much, at least not until i decide to change the story or adjust it.
The characters are anthro so please keep that in mind, and also note that the image used is from STTheo of Deviantart who i asked with expressed permission about his Helldiver units and their designs, which i altered for my OCs, so keep that in mind. And we might see some other things come around as the story progresses. So i'm not sure how it will go.

The Legions of Hell are on the run, and Doomguy has finally found the portal that might lead him home. Emphasis on Might. For all he know's the portal could throw him right back into Hell.

Deciding to give it a go, Doomguy steps through the gate and finds himself in a place far more terrifying than Hell had ever been...Ponyville, Equestria. Worse off, the technicolor ponies who live there won't leave him alone!

Will Doomguy survive to kick-ass another day?
