- First Episode: The Big O (Dub) EP 1 Full DVD
Paradigm City, a city of amnesia and a place of belonging. It remains populated by forgotten pasts and the ruins of their labors due to a calamity 40 years ago. Shrouded in a fog-like mystery, it is up to people like Roger Smith to shine a light through the mist. Acting as a professional negotiator and suave agent, Roger is a self-tailored ladies man whose only love is for funeral black. However, as he gets deeply involved with his clients, what often starts as a simple negotiation evolves into Roger saving Paradigm from crime and peril.
In the process, Roger stumbles even deeper into the untold folds of the city. As a rule, things are hardly ever as they appear. Serving as gray knight in a gray world, Roger is not without allies. By his side are Norman, a loyal and widely skilled butler, and Dorothy, a human-like android with deadpan snark. Together with the relic Big O, a jet-black mecha of gargantuan size and weight, they help Roger serve iron justice to Paradigm’s lurking villains as he discovers the truth about 40 years ago.
