Earning a reputation for crazy piloting skill and tactical genius, traits that pilots rarely have both of, he enters the Normandy crew as a secondary pilot to stop Saren and his Geth. (Tali/OC) (M for violence, sexual themes, profainity, dark themes) My first fanfic, please critique as required! Some plot alteration

In 1958, NATO and the Warsaw Pact come into contact with a hostile UFO. It seemed to defy the laws of physics with the way it moved and the way it's mass seemed to almost...fluctuate. In a joint effort, the two powers defeated the aliens, but only just. Now, the aliens have returned, and only one organization has any hope of stopping them: the Xenonauts.

A single spark can ignite a flame that will consume the lives of many. From a battle over a lonely relay, to a treaty signed on a space station that has acted as the crypt for a thousand civilizations, this is the first contact war

Spans the Mass Effect Trilogy.

The Citadel council learns about the multiverse and just how scary or friendly the new species they’re about to meet can get. (Rated M to be safe due to games such as Halo, Cyberpunk, Dead Space, Dune, and really just anything related like that)

Betrayed by the Galaxy she saved. Her life taken from her. Her only thoughts reform it. Even if she must destroy the very Galaxy she saved. She will save it from themselves yet again I do not own anything Mass Effect. Simply the story line. And Ideas from Call Of Duty Ghosts. Did some simple editing mostly time scale after the war and before current events. Will do more editing

Before the final charge to the Citadel Shepard is locked away captain's cabin thinking over. Everything that will happen has already happened. Going to change this story a little bit in some ways. I thought of adding something called the Rise of Humanity and fall of the Asari, Turians, and Salarians/ will be revamping. I am going to be added Andromeda chapters soon

After too much killing, after too many hard choices in service of the alliance, Cyra, the eldest of Shepard's Asari daugthers, starts her life anew on a frontier world in the Terminus Systems.

Jane has to wrestle with the circumstances of her creation and forge a new identity beyond the shadow of the galaxy's biggest hero.

I think we can all agree waking up as a guy in a woman's body would be jarring to say the least. Waking up as an asari? Horrifying. But waking up as what I had the incredible misfortune to be... Let's just say I wouldn't bet on me surviving long enough to see the Reapers make their grand debut. Asari SI, starts just before ME1.

An alienated, brought back from the dead war hero is thrust back into a galaxy unknowingly on the brink of annihilation. With the sole goal of ensuring a galactic future still exists, Commander Shepard's mission depends on the crew he assembles, on the choices he makes, and on the loyalties he gains.

What happens when humanity enters the galactic stage not as the race that got attacked by the turians for breaking a law they weren't aware of, but as the race that saved a turian platoon from certain death? M for wartime violence, pre ME1 - ME3, no OP humanity.

Coming to terms with being reborn? Doable. Finding out you're in the Mass Effect universe? Slightly more difficult. I know I'm no soldier material but I want to do what I can to help save the galaxy. To that goal I will become one of the worst beings in human society. A businessman and politician. A SI/OC-story of a different kind.

Do we grow, or do we wither? This story takes place in the 10 years after the Reaper War. This is a character driven story, with some larger plot elements at play. Updated every 1-2 weeks.

OK, so as I played through the Mass Effect series, I got this idea that hey what if I combined some of the race's DNA with Human DNA and I got the hybrids (They do not look like movie monster hybrids). I do not own anything to Mass effect save for my OCs. Canon Divergence Reaper AU. What if a single woman changed the course of fate and Saren never discovered Sovereign?

The Reaper War exposed humans to the galactic community at the pinnacle assault on earth. In the aftermath of the Crucible's success, survivors on Earth and stranded galactic races need to work together to survive and thrive. #Alternate First Contact #Slight Canon Manipulation #Post Reapers #Rated M for weight of subjects and occasional mention of smut

The defeat of Sovereign brought reprieve, not victory, and an all too short one as new threats emerge. Amongst their victims is the Normandy, heroine of the hunt for Saren, and with the ship's destruction comes the loss of not just friends but also family. For Shepard, the mission is now one for vengeance, at any cost. Sequel to A Call to Duty.

The world turns, even after a hero falls. Lines are drawn, blood is spilled, and in the shadows, an ancient power stirs. The galaxy needs a hero to rise to the occasion, and live up to her father's legacy...
