Guardbreak is a quiet mech with an overpowering, almost frightening devotion to both Crystal City and Primus. As a member of the Crystal Guard, he takes his duties very seriously, spending as much time as possible working, and doing so often to the point of neglecting his own health. He's very scornful of anyone who doesn't demonstrate as much fanatical dedication as him (which amounts to almost everyone) and especially of those who fight in the war; his general reluctance to talk keeps this mostly under wraps. On the rare occasions he isn't on shift or recharging, he's often training in an attempt to better himself.
