GLaDOS is free of Chell, free to continue testing, when she discovers a portal gun Wheatley tried to repair with duct tape. When the portal gun catastrophically fails, the enrichment center, GLaDOS, and Chell are literally dropped in the middle of Equestria. The mute test subject soon finds the world of ponies far more welcoming than the human world. But GLaDOS sees possibilities. Let the testing begin... for science.

This story is a sequel to Stardust

When Equestria’s newest member of royalty asks for aid to be offered to her friends from abroad, the best and the brightest volunteer to serve. Captain Steel Song of the Dusk Guard are immediately mobilized to help XCOM defend their world from the enemies that besiege them. However, their first joint operation with the humans takes a turn for the worse and they quickly find themselves fighting for their lives against the full force of the monsters that threaten Earth.

(Now has it's own section on TVTropes as part of the Stardust series!)

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

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.

General Iroh. Fire Nation hero. First born son of Fire Lord Azulan. The Dragon of the West. It was thought he would be the greatest warrior in the history of the Fire Nation.

But all that changed when the war claimed his son's life. This changed him, and he turned his back on the war.

This was a necessary event. Iroh had a role to play in bringing balance back to the world...but to play that role, he first had to be broken down, so that he could be rebuilt. This truth was self evident in the spirit realm.

But one particular spirit felt this was unfair to Iroh. The wheels of fate are cruel to those caught in the gears, but this particular spirit felt that Iroh deserved kindness. And so this spirit sent Iroh one who would help him to rebuild himself.

And so, shortly after his son's funeral, Iroh would find a creature sent by the spirits, the likes of which he never would have imagined...a pretty pink pony princess.

Somepony to love...and be loved by.

Part of the PWNY-verse.

Unfortunately for Starlight, her return is exactly what they've been hoping for.

Inspired by the ending of FNAF 3.

Teaming up with fellow survivor Isaac Clarke, Twilight attempts to escape the abominations and find her way back home. But can she really trust Isaac's sanity?
