Shin Mazinger-1

A modern reboot of the classic 70's Go Nagai anime that blends in Devilman and Mao Dante with the Greek-inspired mythos from the original Mazinger manga. Kouji Kabuto lives with his brother Shiro and his genius grandfather Juuzo, and attends high school in his hometown of Atami. When Juuzo's old colleague, the mad scientist and renowned biologist Doctor Hell (a real winner there, right?) returns to take control of the world with his army of mechanical monsters (Kikaiju), Kouji is forced to accept the mantle of Japan's protector - in the 20-ton, rocket-fisting, laser-shooting, Breast Firing "Fortress of Iron," Mazinger Z!
