"Enemy threat detected. Initiating combat protocols".
The D0B3RM4N units are loyal guardians to people and places, putting up a fight if need be.
Their main (and only) weapons are their fists of steel, which they can rotate like a drill, or fire off up to a certain distance. They also have thrusters on their elbows and the back of their shoes to add power to their punches.
Despite their size, they're deceptively fast, fitting for a boxer-style fighter, as the aforementioned thrusters also add extra mobility. Their frames are tough but flexible, so they can take hits as well as they deal them.
Their personalities can be easily programmed depending of the tastes of the user.
