Equestria is at war. The Crystal Empire is winning a war of attrition and a new phase of the war is about to begin, waged with living weapons that Equestria's armies can't hope to defeat on their own.
Hope comes in many forms. Today it comes in the form of a blank-flanked scientist and a crew of dishonorably discharged soldiers, criminals, and worse. They'll do what they have to do to achieve their goals, and Equestria might even get saved in the process.
A pastiche incorporating some elements from Getter Robo, Evangelion, and Devilman.
