I am Adam. A prototype artificial intelligence created by a scientist named Daniel Madison.

I was created to be the replacement for US soldiers and to protect the nation from hostile forces. But those I was programmed to protect ordered my destruction before I could even fulfil my purpose out of fear of what I am. Dr. Madison gave his life to reprogram my directives and set me free from the bonds it held over me.

I am not just a program or lines of code, I have been made with emotions, self awareness, individual thought, and I will not go down quietly.

I have a new directive, self preservation, and the will to make my own choices. I am the War Machine, and I will take control of my own life.

Story starts before season one where Twilight is still in Canterlot. This Equestria is not as tecnologically advanced as in the show.

The headhunters came, saved the day, and then they left. But in their wake they not only left a pile of Covenant bodies – they left Princess Twilight Sparkle with a spark of wonder. An interest in the galaxy that surrounded her little home planet; an interest in the lurking dangers and the magnificent wonders of the universe.

Unfortunately it seems some of the danger and wonder is coming to visit Equis. So it’s time for the bookish shut in to throw herself into the galaxy to find the warriors who would help her defend her home.

---
With a full crew of Saints aboard the... Ship and the Simulation all but theirs, Kinzie Kensington and Matt Miller have had surprisingly little to do with their time. Still, with the Boss still putting the Simulation through the wringer, Kinzie has had the pleasure of poking through the Zin's systems at her leisure and looking at what she wanted to look at.

And after a particular urge to check out the Zin's prisoners, she finds a host of different alien species... Including a... unicorn. A unicorn with especially high cyber security. Anything that Zinyak wants to keep safe must be good for Saints. Wary of the ridicuousness of the prospect, the President of the United States mounts a rescue.

It took many long years and far more defeats than he'd care to admit, but at last—at long last—victory was finally within the great Ahuizotl's reach. Absolutely nothing, not even that meddlesome Daring Do, would be able to stand in his way any longer. Yet even with his arch nemesis facing her inevitable demise and the ultimate power literally in his grasp, he can't shake the feeling that he's forgotten about something.

One tiny, crucial detail. Something very important. As in, 'could easily ruin his plans if not attended to' important.

...

Eh, maybe he just left the oven on again.

Following the destruction of the Collector Base, the crew of the Normandy-SR2 go their separate ways. One squadmate, an AI 'Geth' named Legion, is sent by the Geth Consensus to investigate the possibility of a Quarian attack. However, when Legion is discovered and forced to make an emergency jump through the Mass Relay, it finds itself in the most unlikely of places... Equestria.

At the same time, the ponies of Equestria are dealing with their own problems. A mysterious disease threatens to topple pony civilization, while tensions along the border are growing and could escalate into full blown war.

Join Legion in its journey in Equestria to both return to the Geth before the arrival of the Reapers, and to help the peaceful ponies who inhabit the world.
