With a negotiator, it would be 'made sure the negotiations never work out. However, the creators thought this to be too ordinary, and turned him into a Negotiator. Inspired by detective shows like Oretachi wa Tenshi da! ( We Are Angels!) and Tantei Monogatari ( Detective Story), Roger was to be a private eye. Sato's original concept was a giant city-smashing robot piloted by a man in black, Roger Smith. Looking to create something distinguishable from the Gundam franchise, they used as a basis old super robot series and American TV shows. In 1996, Keichii Sato and Kazuyoshi Katayama began work on what would become The Big O. Roger is voiced by Mitsuru Miyamoto (Japanese) and Steven Blum (English). The character, originally envisioned as a private eye, shows influences from Batman, James Bond and Giant Robo's Daisaku Kusama. 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. Despite this, he displays a certain aversion to the Paradigm Corporation, and takes the jobs he gets from them only if they happen to involve a threat to the city itself or are of personal interest to him. He'd negotiate anything for anyone, but he is a professional and expects the parties to behave professionally. His job entails finding a resolution for the troubles of Paradigm City, the 'City of Amnesia'. He is the Negotiator (ネゴシエイター, Negoshieitā?). Roger Smith (ロジャー・スミス, Rojā Sumisu?) is the series protagonist.
