Roujin Z

The story revolves around a new team of "Toei robot girls" named "Team Z" that is made up of three girls based on Toei's Mazinger Z franchise: Mazinger Z, Great Mazinger, and UFO Robot Grendizer. Usually they perform in activities around Nerima ward in Tokyo to raise the awareness of the promising future energy source "Photon Power" (koushiryoku). However, there are times when "Mechanical Beast" team of girls emerge from the "Subterranean Empire" and attempt to steal the energy. Thus "Team Z" has to battle them to prevent this, though sometimes they just go and beat up the "bad girls" to relieve stress.

From the island of Bardos in the Aegean Sea comes a new threat to humanity in the form of Doctor Hell and his army of mechanical beasts. However, a new hero stands in his way: Mazinger Z, a giant robot built out of the indestructible metal chogokin and equipped with an arsenal of advanced weaponry. Piloting Mazinger Z is hotheaded teenager Kouji Kabuto, who strives to avenge the death of his grandfather and protect Japan from Doctor Hell's forces.

A young man named Akitsu Masato is `captured` by a secret govt. project known as "Last Guardian". He is told that his life as a normal student was all a lie, and that his real destiny is to be the pilot of a great robot called "Zeorymer of the Heavens". The truth of this is hammered in when Masato sees his `parents` accept payment for raising him. The Last Guardian is preparing for the resurrection of "Hau Dragon", an organization bent on world conquest. 15 years ago, Hau Dragon built 8 great robots. Each of the mecha represents a force of nature. However, before any of the robots could be used, their creater Kihara Masaki destroyed the robots except for the leader: Zeorymer. He took Zeorymer and an embryo to the government. The embryo became the boy Masato. Now, Hau Dragon has rebuilt the other 7 mecha and wants the 8th. It will be up to Masato and Himuro to pilot Zeorymer and fight against the Hau Dragon, but neither Masato or Himuro are all that they seem.

In the year 2050 A.D, approximately 1/10th of Japan is now under water due to the global warming effect. The city of Tokyo was no exception. The economy of Japan is crippled from this disaster and the government is willing for anything to help revive the country. As a result, the Japanese government forms "JESAS", a military foundation that has evil intentions of controlling Japan's future. JESAS handles the dumping of nuclear wastes into outer space. To insure their protection from other countries, JESAS has developed "R.B." Robotic Weaponry, which is controlled by pilots with "A.I. (Accurate Intuition)". On the opposite side of the law is the "Green Frontier", a united protection agency that was formed by countries sharing the same beliefs, to save the Earth. Featuring JESAS pilots Kanna and Kazuto and Green Frontier's Doota Kang and Mira Yu, these four youngsters will decide the fate of the Earth through love, friendship and the passion for their duty.
