Synopsis

The Mycenae Empire strikes without warning, plunging the world into chaos. Led by the Great General of Darkness, they're determined to conquer Earth—and they're actually winning. Mazinger Z's forces are getting wiped out by seven powerful generals, each commanding their own army of Warrior Beasts. To make things worse, Archduke Gorgon is hunting Koji Kabuto, trying to kill him before he can access Mazinkaiser. But then a mysterious red light appears over Mt. Fuji. It's a sign that the greatest battle the world has ever seen is about to begin.
