Roger Smith is the main character of the series Big O. He's a wealthy man, with a large mansion, a butler, and an android companion named R. Dorothy Wayneright. His chosen profession is as a negotiator.
In Act: 14 Roger confessed that "his life was nothing but boring" and that he was adopted by an affluent foster family. In Act: 4, Roger has a vision in which we see a woman. Roger refers to the woman as "mom" before Dorothy interrupts the vision. It is unclear if this is his foster mom, or his biological mother. There are also some photos of a young Roger with paternal and maternal figures in Act: 1, again it is unclear if these are his biological parents or his foster parents. He was given an education at a private academy/school from an unknown sponsor.
Roger eventually joined the Military Police. It was during this time that he developed a rapport with Dastun. He eventually rose to the rank of lieutenant. After some "arbitrary" reason he decided to resign from the Military Police. It is implied in the series that he resigned since he believed the Paradigm Corporation was not concerned with public safety.
Roger later claimed, in Act: 14, that he discovered a "run-down bank" and decided to make it his home. While inside he found Norman who had been waiting for his master to arrive. Roger immediately denied being a "master" but after a while conceded. It was around this time that he was told of Big O by Norman. How he decided to become a negotiator is never revealed. He negotiates for anyone under the expectation that both parties behave professionally. He displays a distrust for the Paradigm Corporation. He only takes a negotiation for them if it is necessary.
In the series finale, Roger indicated that he believed he had retained his memories of the past, but at some point voluntarily removed them for unknown reasons. Various flashbacks throughout the series indicate that this removal may not have been complete.
