The Mega Reversal Machine structure initially appeared as the nervous system of Badan's underground base, the Badan City, with the heart of the machine being a cell to contain Shuu and draw his power, and a mouthpiece for the Generalissimo of Badan at the bottom of the tower. The Mega Reversal Machine then appeared to emerge on the surface as the Great Leader revealed himself following the battle between the Heisei Riders and Showa Riders leaving Gaim as the last Kamen Rider. At that moment, Badan's general, Ambassador Darkness, revealed himself as Ryo Murasame (Kamen Rider ZX), crippling the structure with his Cross Shuriken.
