first alluded in the episode 15 and is the one behind the events of the entire series, having created Vincent and then sent him back to Romdeau to start his plan. Near the end of the series, Proxy One is revealed to be the one who fired the thermonuclear missile Rapture, destroyed Amnesia to hide Vincent's memories and killed Donov Mayer. He is killed by a combination of Vincent's attacks and sunlight.


As far as Proxies go, Proxy One is considered to be the strongest fighter of all 300 Proxies that were created by the Proxy Project. Capable of stopping the flames and radiation of two thermonuclear bombs, and suppressing their effect to the point that damages appeared to have happened long ago, merely by "hand waving" the flames away.


By manipulating Raul Creed 's emotions, Proxy One caused at least one missile launch, decimating several Dome Cities. In his view, humanity had destroyed the planet and then fled, leaving Proxies to resurrect the world and subsequently die off when the clouds parted. Enraged at this injustice, Proxy One sought to wipe out humanity by instigating warfare and nuclear missile launches, and while he was ultimately unsuccessful, it is possible that only Re-l Mayer and Vincent Law remain (the proverbial Adam and Eve). Though Proxy One was defeated by Vincent Law (Ergo Proxy) and his plans to wipe out humanity failed, Proxy One found some solace in the fact that Vincent would somehow survive the coming of sunlight with his Amrita Cells intact: in short, despite the coming of the sun, Vincent Law remains Ergo Proxy, the Agent of Death.
