Father Roberto Shijima
He is a figure within the cult known as the Order of Silence and Darkness. Shijima can become the Dummy Dopant who can assume any form he wishes. Among these forms is the Death Dopant, using his powers to mimic the real Death Dopant's ability to bring people back from the grave. Using the Death Dopant's form, Father Shijima targets upper class people by assuming the forms of their recently deceased relatives to frighten them and push them to an early grave. He uses this power on Asami Mutsuki by assuming the identity of her sister Erika, while assuming Soukichi Narumi's form to discourage Shotaro's interference. Once exposed, the Dummy Dopant evades Double as he finds himself in the middle of Decade's fight with Super Shocker, where he takes control of the Mammoth Mecha. However, the Dummy Dopant meets his end when he is assimilated by the Neo Organism as it becomes the inhuman Ultimate D. In materials to promote the film, the Dummy Dopant was referred to as the "mysterious Dopant".
