Synopsis

After taking down Dr. Hell, Kouji finally gets to relax—until a mysterious prophet shows up with a dire warning. Strange new mechanical beasts start popping up worldwide, causing destruction everywhere. Kouji and Mazinger Z jump back into action, but they're quickly overwhelmed. The odds are stacked against them. This movie bridges the gap between the original Mazinger Z series and Great Mazinger. It's basically the introduction to Great Mazinger and its main villains, the Mikene Empire.
