(((The design of the RX-178 Gundam Mk-II A direct descendant of the RX-78-2 Gundam developed by the Titans, the Gundam Mk-II is the first mobile suit to utilize the new movable frame concept. In this new concept, rather than merely serving as a structural framework, the movable frame incorporates all the mobile suit's vital mechanisms, including the actuators and control systems required for movement, and excludes the mobile suit's weapons, armor, and propellant tanks. This approach dramatically improves the mobile suit's responsiveness, reliability, and energy efficiency, as well as making it far more agile than traditional designs.
