Shuttlebase is the Earth Defense Force's primary mobile command center and carrier mecha. Resembling a massive space shuttle, this flying fortress houses and deploys the three machines that form Change Robo.

Jet Changer 1 is a high-speed tactical fighter piloted by Hiryuu Tsurugi, Change Dragon. It serves as the primary aerial component and forms the head and torso of Change Robo.

Helichanger 2 is a military helicopter piloted by Shou Hayate, Change Griffon, and Sayaka Nagisa, Change Mermaid. During the Earth Conversion sequence, it forms Change Robo's arms and chest armor.

Landchanger 3 is a heavy-duty armored ground vehicle piloted by Yuuma Oozora, Change Pegasus, and Mai Tsubasa, Change Phoenix. It forms the legs and stable lower body of Change Robo.

Change Robo is the Changemen's giant robot, formed through the "Earth Conversion!" command when Jet Changer 1, Helichanger 2, and Landchanger 3 combine.

Its primary weapon is the Blitzkrieg Sword, which can perform the Super Thunderbolt, Swallow Reversal, and Wind Wheel Cut finishers. Change Robo is also armed with Change Robo Missiles, Change Vulcans, and a durable Change Shield for defense.
