Character Arc

Roger Smith is the central figure of The Big O, a composed and well-mannered Negotiator who resolves disputes throughout Paradigm City. He lives by a personal code, favors dark suits, and keeps a measured, gentlemanly demeanor even in dangerous situations. A former member of the city's police force, he now works independently, taking on sensitive cases that others cannot handle.

When negotiation alone cannot settle a conflict, Roger calls upon the Big O, a towering black mecha he treats as a last resort. His partnership with the android R. Dorothy Wayneright and his butler Norman grounds the series, and his interactions with Dorothy in particular add warmth and gentle humor to an otherwise moody world.

As the series progresses, Roger is increasingly entangled in the mystery of Paradigm City's lost memories. Questions about his own origins, his connection to the Big O, and the truth behind the city's amnesia push his arc from episodic cases toward the show's larger, more philosophical themes.
