Technology & Combat Characteristics

A customized Gunpla which uses the MSF-007 Gundam Mk-III as its base kit. It has a basic custom build style that focuses on enhancing its armor and mobility, and it is capable of producing power surpassing its specifications due to the fighting techniques of its Diver, Sid. Its armaments include Beam Rifles and Beam Sabers, which are basic weapons, but the extreme toughness of the Tertium has hidden expandability that enables it to wield massive non-standard equipment, such as the Hyper Burst Lance. The Gundam Tertium later became the MSF-007SS Gundam Seltsam, and the latter's armament composition succeeded in fully drawing out the potential of the Tertium.
