The Big O(1999)

The Big O

The official comic adaptation of Bandai's Cartoon Network hit, a stylish "manga meets film noir" story which goes BEYOND the plot of the TV series! 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 only 40 years 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 MegaDeuses--giant robots created by the city's former inhabitants, or perhaps by the forgetful citizens themselves. When crime and madness strike, Roger Smith brings the guilty to justice with the giant robot called THE BIG O.
