Following the death of her wingmate, Operator 5431N4 accepts experimental new enhancements in order to compensate for her decreased utility to the state. Having only ever trained as part of a paired unit, she finds herself not knowing how to exist outside of it. It is fortunate that her new exo-suit seems perfectly able to compensate for her deficiencies, able to cover her weaknesses, enhance her mobility, and complete her in a way that she believed no longer possible. Even so, despite her stellar performance, it seems that interfacing with the suit has unexpected feedback and consequences ... Attack Dog is a short, brutal story in the realm of queer body horror, inspired by the works of various transfem creators.
