Z Mazinger

Ζ 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.
Set in contemporary times, the battle of the Gods continues. Hades has returned to attack the Earth and exterminate the human race, and to protect it Zeus sends a robot born from him, Zeta Mazinger.
The robot is given by chance to a student called Koji Kabuto and together with Aphrodite and other classic Mazinger characters such as Tetsuya he defends the planet. Many other gods are involved, and their relationships of love and envy are part of the plot.
Some elements of Zeta Mazinger appear in Mazinger Z: The Impact!, the most prominent being the apparition of Zeus in his Zeta Mazinger form.
