The MAC Empire, AKA MACE, is a faction of RoboMACs determined to take their rightful place at the top of the evolutionary ladder by wiping out the next rung below them— humanity!
They hail from the RoboMACs 2163 universe. They control about 70% of Luna, a shining metal city that fully covers one hemisphere of the moon. They are constantly at war with the Guardians, humanity's defenders. Though they have many designs, they all wear a teardrop-shaped insignia bearing a highly stylized morningstar (see top of page).
