The Mercurius was designed with defensive strategy in mind, and was armed with a small beam gun and a large shield, called a "Crash Shield," which had a powerful beam saber integrated into it. It was also equipped with a set of ten planet defensors, which were small disc-shaped objects which projected an energy shield to protect the Mercurius or another mobile suit from virtually any attack. The shield is powerful enough that it could even block a shot from XXXG-00W0 Wing Gundam Zero buster rifles, but a subsequent shot would prove too much for it. They were stored in a rack on the back of the Mercurius, where they were charged by the suit's reactor. The Mercurius was designed to operate together with its brother, OZ-13MSX1 Vayeate, with one covering the other when in battle. Both suits have a head cover that defends the sensors but limits the vision. A second Mercurius controlled by Mobile Doll AI System was later built by White Fang. The planet defensors were later used in OZ's mass production mobile doll, the OZ-02MD Virgo, and subsequently by the White Fang on their captured Virgo troops which included the upgraded WF-02MD Virgo II.
