Big O is a show centered around Paradigm City, a place in which all inhabitants had lost their memory 40 years prior. The main character is a very skilled private investigator/negotiator named Roger Smith. He and his android companion R. Dorothy Wayneright solve the mysteries of the city, supposedly the last place civilization exists in this post-apocalyptic world. The show is named after the titular Megadeus, Big O, a mecha which is owned and under the command of Roger Smith himself. While Roger and Dorothy, aided by Military Police commander Dan Dastun, delve deeper into the city's mysteries and uncover more of the truth, they come closer to confrontation with the mysterious Union, supposedly another surviving society, and the secrets hidden underneath the city itself, unbeknownst to all, including the powerful Alex Rosewater.
