These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Even still, "Fire Wars" must be mentioned for being quite possibly the most Hot-Blooded song the group has ever churned out.
Let's not forget the awesome Majin Kenzan!! insert song in the movie, accompanying Mazinkaiser's triumphant return to Earth, and the ensuing Curb-Stomp Battle it inflicts thereafter (see Dynamic Entry on the main page).
"Theme of Mazinkaiser" by JAM Project founder (and singer of the original Mazinger Z theme) Ichiro Mizuki
The ED, "Tornado", is also by JAM Project, and is also awesome.
God-Mode Sue: The titular machine, because nothing can destroy it, not even drowning it in molten lava. One of the few Humongous Mecha to never gets its paintjob scratched, too.
Although its Super Mode takes a while to control and Kouji Kabuto does have lots of trouble with it at first, nearly destroying the Photonic Research Institute and the Great Mazinger and seriously injuring Tetsuya Tsurugi during its rampage.
Superlative Dubbing: while there are a few pronunciation-emphasis problems in the dub, (Sa-YA-ka, Ka-BU-to, Ma-ZIN-ger, etc), the acting overall is excellent; in particular, Robert Newell and John Paul Shepard are nearly perfect in their respective roles of Koji and Dr. Hell.
