Ζ Mazinger (Ζマジンガー, Zēta Majingā; sometimes romanized as Zeta Mazinger) is a retelling of the Mazinger Z story by Go Nagai, mixing it with ancient Greek mythology. Here, Greek myths are the human testimony of the epic battles between robots piloted by extraterrestrials. The appearance of the robot remains similar to the original Mazinger, but with a more modern look.
