Roger Smith

He is the Negotiator. His job entails finding a resolution for the troubles of Paradigm City, the "City of Amnesia". He'd negotiate anything for anyone, but he is a professional and expects the parties to behave professionally. 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.
