Mechanical Soldiers are the most numerous of Constructs, those created by Dracar as will-less, expendable fodder for their war against free will. They are created without the ability to feel pain, or temperature, or form facial expressions, or alter tone of voice. They have no personalities or individuality, built solely with function in mind, bearing labels of letters and numbers as "names". They are not so much nonbinary or agender as they are lacking in the ability to conceptualize such a thing for themselves, as its irrelevant to their role.

Relations of other Races
Mechanical Soldiers lack the ability to form thoughts and opinions outside of the tasks Dracar has created them to accomplish. Their universal opinion of non-Mechanus creatures is that they ought to be destroyed so that Dracar's will might be brought to fruition. They are viewed as dangerous and avoided and fought with intensity, lest one be destroyed by them instead.
