Steel Jeeg

The story tells about Hiroshi Shiba, a car racer who is mortally wounded on a laboratory accident, but restored to life by his father, Professor Shiba, a talented scientist/archeologist, who is incidentally investigating the relics of the ancient Yamatai Kingdom. The professor discovers a tiny bronze bell with sorcerous powers, and shortly afterwards he is murdered by the henchmen of Queen Himika, the ruler of the Yamatai (sometimes translated as Jamatai) Kingdom, who wants to seize the ancient bell and its power.

Go Nagai returns to one of his most famous creations: Jeeg, the robot created with Tatsuya Yasuda. This time flanked by Shinobu Kaze, grappling with a new version of the famous steel warrior, who, once again, will save the future of humanity. The opera is captured with a decidedly hard boiled imprint, between political intrigues and martial arts, almost evoking Hong Kong action cinema.

The ultimate cross over manga featuring Mazinger Z, Great Mazinger, Grendizer, Getter Robo, Getter Robo G and Jeeg! These all-stars band together in order to defend Earth from cosmic evil. This manga is in the same vein as all those old Toei cross over movies, and the self-parody gets pretty strong later on.

Mazinger Otome depicts the mechas of the Mazinger franchise and Steel Jeeg series as androids where they fit into regular life. It follows the android girls that make up the cast as they deal with life in high school and from the school delinquents the Mechanical Beast Army. The main protagonist is Seto Magami, an android based on the Mazinger Z who is treated as the granddaughter of Juzo Magami. Later with the introduction of the New Mazinger Army, there are heated arguments and fights between them and the originals.
