From highway hauler to heavy-duty HQ—MDU (Mobile Defense Unit) rolls in with muscle and mission control in one! The MDU (Mobile Defense Unit) is the MASK team's ultimate mobile command center—disguised as an unassuming semi-truck until it reveals its true strength. With a quick conversion, the rig becomes a fully equipped Mobile Defense Headquarters ready for action. The Loyal Subjects' M.A.S.K. MDU brings the battle to the road with upgraded sculpting, rubber tires, and authentic decals. Dual-action switches activate a spring-loaded enemy ejector seat and front-mounted battering ram, while an internal missile launcher and Recon Rover deliver backup firepower and mobility. Includes Matt Trakker in his ULTRA FLASH mask—MASK's fearless leader—and Bruce Sato in his LIFTER mask, the team's trusted mechanical engineer and vehicle specialist.
