This is also known as “Mazinkaiser Vs. The Dark General”. It is a sort of remake of the 70’s Mazinger Z movie, “Mazinger Z Vs. The Dark General”. This is the last OVA (Original Video Animation) ever produced from the Mazinkaiser series up to date and it is totally independent, story-wise, from the other 7 OVA’s. The original Mazinger Z movie was loosely based on the 92nd episode of the Mazinger Z original series. On that episode GreatMazinger is introduced when the Dark General exacts revenge for the death of Dr. Hell, Mazinger Z’s former enemy. The plot of this Mazinkaiser OVA is quite different from the original, although the basic premise is the same. The Dark General wants to avenge the death of Dr. Hell that occured on the last episode of the previous OVA 7-part series. But, besides the premise, everything else is a fresh new story. There is even mention of Mazinkaiser able to operate and defend the earth from outer space, but there has been no more OVA’s from this series. The previous 7-part OVA series of Mazinkaiser was dubbed in english and distributed by ADV Films as two separate DVD volumes, but this stand alone OVA has yet to be distributed in dubbed version. I have only seen it in Japanese with English subtitles.
