Megadeus

"Megadeus" (メガデウス, Megadeusu?) is the name given to the giant robots of The Big O anime series. Forty years prior to the events of the series, the world was turned into a vast desert wasteland and the survivors were left without memories. The megadeuses are portrayed as remnants of the previous civilization, a lost technology few citizens of Paradigm know how to control. The word is a blend of the Greek Megas, meaning "Great", and the Latin deus, meaning "god". The pilot of a Megadeus is a dominus (ドミュナス, domyunasu?), taken from Latin.
