Baron Ashura's falls in the Pacific Ocean!!

Synopsis

Locked away in the dungeon beneath Hell Castle, Baron Ashura can no longer even get the Iron Cross Corps to follow his orders. With his pride wounded, he breaks out and, aboard Grand Duke Gorgon's Mechanical Beast Elephance γ3, attacks the Photon Power Laboratory. Meanwhile, Mazinger Z, lured out by a missile strike, is locked in a decisive battle with the Fortress Vouud. Vouud is sent to the bottom by a self-destructive ramming attack, but Mazinger Z's systems are also wrecked, leaving him stranded and unable to move on the sea floor.
