Roger Smith is the main protagonist and narrator of the anime series The Big O. His chosen profession is as a negotiator, whose job entails finding a resolution for the troubles of Paradigm City, the "City of Amnesia", and is said to be the absolute best at what he does. When memories betray the people and force them to reawaken monstrosities of the city's past, Roger's only option is to fight back with a monstrosity of his own, the black Megadeus Big O.
He is voiced by Mitsuru Miyamoto in the Japanese version and Steve Blum in the English version.
