===Plot===
{{Main|List of The Big O characters}}

After failing to negotiate with terrorists at the cost of his client's life, Roger Smith is obligated to care for Dorothy Wayneright, a young female android. Over the course of the series, Roger Smith continues to accept negotiation work from the residents of Paradigm City, he often leads to uncovering the nature and mystery of Paradigm City and encountering megadeus or other giant enemies that require Big O. Supporting characters are Angel, a mysterious woman in search of memories; Dan Dastun, chief of the military police of Paradigm city and old friend of Roger Smith; and Norman Burg, the butler of Roger Smith and mechanic of Big O.

The main antagonist is [[Alex Rosewater]], chairman of Paradigm City whose goal is to revive the megadeus "Big Fau" in attempts to become the god of Paradigm City. Other recurring antagonists are Jason Beck, criminal and con-artist attempting to humiliate Roger Smith; Schwarzwald, an ex-reporter obsessed with finding the truth of Paradigm City and also pilot of the megadeus "Big Duo"; Vera Ronstadt, leader of a group of foreigners known as the Union searching for memories and revenge against Paradigm City; and Alan Gabriel, a cyborg assassin working for Alex Rosewater and the Union.

The series ends with the awakening of a new megadeus, and the revelation that the world is a [[simulated reality]]. A climactic battle ensues between Big O and Big Fau, after which reality is systematically erased by the new megadeus, an incarnation of Angel, recognized as "Big Venus" by Dorothy. Roger implores Angel to "let go of the past" regardless of its existential reality, and focus only on the present and the future. In an isolated control room, the real Angel observes Roger and her past encounters with him on a series of television monitors. On the control panel lies ''Metropolis'', a book featured prominently since the thirteenth episode; the cover features an illustration of angel wings and gives the author's name as "Angel Rosewater". Big Venus and Big O physically merge, causing the virtual reality to reset. The final scene shows Roger Smith driving down a restored Paradigm city with Dorothy and Angel observing him from the side of the road.
