"Fight! Iczer-One" is one of the first OAV, being produced in 1985 by AIC. It's half science-fiction and half horror with some gore scenes, really nasty monsters and a beautiful android, a Girl-Warrior named Iczer-1.
The story is much more complex than what it may seems at first
glance and everything has an explanation even if it isn't obvious the
first time you watch the anime : As I already said it in my introduction,
many events are explained in brief flash-backs in Act III. It isn't a
funny or "light mood" anime. It's even totally the reverse, and they
didn't feared to kill important characters but it's filled with
emotions and has a true ending. As Toshihiro Hirano said it in an
interview : "...As far as I'm concerned, the story ends at the end of the video
...Even if we drew the designs and art seriously,
there's no way there could be a legitimate sequel in the world of Iczer.
(Speaking of the Iczer-3 radio drama)."
The music composed by Michiaki Watanabe fit perfectly the mood of the anime, ranging from military march, when the human army attempt their puny attack, to the gothic theme of the alien Cthuwulf and their bio-engineered monsters.
