Viz Edition Release Date: November 5, 2002
Paradigm City is the city of amnesia--40 years ago, something happened that wiped out the memories of the residents, forcing them to recreate their culture from scattered fragments.
In this world, just four decades old, Roger Smith is a "negotiator"--a go-between for police, citizens and criminals in high-risk diplomatic situations. But something else survives from the forgotten past. They are the MegaDeus, giant robots of apocalyptic power. When crime and madness strike, Roger Smith brings the guilty to justice with a MegaDeus called the Big O.
More than a straight adaptation of the hit Cartoon Network series, the manga includes the prequel to events in the Big O anime, plus many completely new stories.
