A triumphant Sephiroth arrives in a new galaxy looking for life to conquer and a place to build his Promised Land. Commander Shepard, now in control of the Reaper fleet, will defend her galaxy at any cost. (Reapers vs Sephiroth, no pairings, rampant eldritch sci-fi nonsense. Rated T for violence.)

Sephiroth became one with the Lifestream and sailed the cosmos. The Crucible didn't fire, Shepard couldn't defeat the Reapers, and the war raged on. The two collide.

The Crucible dumps Shepard on Gaia. The first human Spectre becomes the first female SOLDIER, and their first Sniper. Her uncanny ability to bring reason to unreasonable situations will alter the fate of the entire planet, but especially that of her three First Class friends. FF7 / ME3

In a black forest, Shepard finally sat down. Takes place at the tail end of N7SOLDIER, companion fic.

Shepard is a commander in the merfolk's surface guard, patrolling the shipping lanes and holding back the reach of the human empire. Sephiroth is a deep sea merman who has spent his entire life in a tank, unaware of what he truly is. Mermaid AU. Rated T for violence.

The crucible dropped Shepard on the remote planet Gaia, Shinra brought her into the science department, where she found Sephiroth, still a child and a prisoner of the Science Department. That was unacceptable. Adoption AU, no pairings, rated for violence and human experimentation.

Two soldiers who outlived their wars find peace together. Happy-ending where everyone gets to process their PTSD. Slight pairing, mostly gen.

Soulmates have a mental connection, even when they're a galaxy apart.

A dangerous enemy has traveled from one world to another, and only the combined forces of two teams can stop him. ME2/FFVII Crossover

With the universe at stake, the clandestine group known as Cerberus has recruited a powerful and solitary warrior. With the help of a team consisting of people from many different worlds, he will try and defeat an enemy as mysterious as he is powerful.
