Once again, Dr. Hell has pitted himself against Mazinger Z - but this time, he actually succeeds! Armed with an electromagnetic ray and net, Dr. Hell manages to capture his arch nemesis and put him out of commission; and with Mazinger Z no longer a threat, Dr. Hell then attacks the Photoatomic Research Institute as the last obstacle in his quest for world domination. Boss and Aphrodite are doing their best to defend it, but can they really defeat the man who beat Mazinger Z? Will Dr. Hell finally achieve world domination, or will our hero find a way to break free and fight once more?
