The main user of the Commander Memory was Hiroshi Sagami (相模 広志 Sagami Hiroshi), a corrupt police officer within the ranks of the Futo police force. Three years prior, Sagami lost his wife when she was gunned down by a criminal he arrested prior. Furious with the conclusion that law itself can never reform criminals, Sagami obtained the Commander Memory and became judge, jury, and executioner as the Commander Dopant, executing any criminals he comes across regardless of the severity of their crimes. Known as the One Dopant Army (ワン・ドーパント・アーミー Wan Dōpanto Āmī), the Commander Dopant can create Masked Soldiers to fight for him with his gauntlet that materializes and destroys matter. After obtaining the Gaia Memory Enhancing Adapter from Aoi Katsuragi, the daughter of a petty thief he murdered in cold blood, the Commander Dopant acquires an upgraded form with the ability to fire a barrage of missiles. Seeing Ryu Terui as a kindred spirit, Sagami kidnapped Akiko to force Ryu to open his heart back to brutal vengeance, making himself the villain and intending to have Ryu succeed his work. However, refusing to go down that path again, Ryu managed to get the Gaia Memory Enhancing Adapter and used it to save his wife and defeat the Commander Dopant. Afterwards, Sagami was taken into custody.
