A taste of the Pacific Rim/Mass Effect AU
For Avery Shepard things went to hell in the short period of ten minutes.
They both woke up - her in the bottom bunker and him on the upper one under strict military rules - got dressed with some haste and in under three minutes they were in their Jaeger, Normandy, and dropped on Earth to face another Reaper, codename Knifehead. Then everything had gone to hell when the Reaper had attacked them one-on-one and literally tore Kaidan away from the right side of the Neural Link, forcing Avery to fight alone, unable to move her side of the metal body and into killing the damned Reaper with the wrong cognitive responses.
It did leave a pretty neat scar afterwards.
It also left her stranded on Earth somewhere in the southern hemisphere while the GAAR scrambled to pin-point her location to retrieve their Jaeger.
