is a Japanese anime OVA produced by Brain's Base and Dynamic Productions, based on the Mazinkaiser design that debuted in Super Robot Wars games and the original Mazinger Z manga by Go Nagai. The OVA follows Kouji Kabuto, Tetsuya Tsurugi and the rest of the "Mazinger Team" as they fight against Dr. Hell's Mechanical Beasts while Kouji stumbles upon a forgotten laboratory where he finds Mazinkaiser, the most powerful robot ever built. The series chronicles Kouji's experience with the machine as he copes with Kaiser's power while defeating Dr. Hell's forces. The OVA series was directed by Masahiko Murata (Jinki:Extend, Corpse Princess) and written by Satoru Nishizono and Shinzo Fujita. It was first released on Japan through Home Video from September 25, 2001 to September 25, 2002 with a total of 7 episodes. An epilogue movie titled "Mazinkaiser vs. The Great General of Darkness" was released in theaters on July 25, 2003. Mazinkaiser emulates Go Nagai's character designs, and its operatic plot is supported by a "tongue-in-cheek" cynicism in regard to the gratuitous sex and violence. Some of the Episodes draw their plot elements from the manga itself rather than the TV series. ADV Films once licensed the series in English territories until the company's closure in 2009.

Great is seriously damaged during the initial battle in the series. It became worse when the captured Mazinger Z attacks the Photon Power Labs even though Tetsuya does his best to defend the lab against Mazinger Z. Lastly, the rampaging Mazinkaiser leaves him badly injured while Great Mazinger is a complete wreck. Consequently, he leaves together with Jun to get treated for his injuries. Near the end of the OVA, Tetsuya returns with a new and much more powerful Great, which is discovered in Doctor Juzo Kabuto's laboratory. This is said to be the real Great Mazinger (or "Shin Great Mazinger"). The "true" Great is structurally the same as the earlier version, but the color scheme for the forearms and legs is blue, as in the original 70's version. It is explained that the Great Mazinger made by Doctor Kenzo Kabuto (Kouji's father) is the prototype version seen in the early episodes, whereas Doctor
