Overview
Shinzo, known as in Japan, is an anime television series produced by TV Asahi, Toei Advertising, and Toei Animation. It was directed by Tetsuo Imazawa, with Mayori Sekijima handling series scripts, Sachiko Kamimura designing the characters and Katsumi Horii composing the music. In the series, genetically-altered creatures known as Enterrans take over Earth and rename it in their own image called Enterra. Now three Enterrans have to protect the last human in order to find the hidden sanctuary called Shinzo and restore the human race. The anime focuses primarily on the adventures they undergo while working to accomplish this task, though battle action becomes the main focus in the middle of the series. Due in part to the popularity of Hunter × Hunter in some areas in the competing timeslot, the series struggled with an average viewership of 3.5%, and was cancelled. In the United States, the anime was licensed and dubbed by Saban Entertainment & Buena Vista Television.
Plot
In the distant past, the Guardian of the Milky Way galaxy named Lanancuras began to harbor a desire for more power. Because of his connection to the galaxy, he was able to absorb parts of planets and add them to his strength. As a result, he began invading the worlds he was assigned to protect. In the wake of his destruction, a following of creatures from across the galaxy pledged allegiance to Lanancuras and became known as the Kadrians. Taking notice of his ever-growing power and followers, the other Celestial Guardians confronted him; however, he had become too powerful, and they were defeated. Unable to subdue Lanancuras, the Celestial Guardians each gave up a part of their power and combined it into a single new Guardian, Mushra. In a final desperate attempt, they used Mushra's core by transforming it into a powerful card with which to seal Lanancuras in a prison. The prison was created from the remains of planets that had suffered under Lanancuras' tyranny. Because planets are themselves large beings, their combined strength (along with the power of the card) was able to restrain him. Thus Lanancuras was successfully sealed in a large meteorite.
The meteorite was sent off into the galaxy to be sealed forever. Meanwhile, the way Lanancuras had increased his strength had consequences on the planets of the Milky Way On Earth, around the 22nd century, it was in the shape of a virus that merged with human DNA and destroyed the humans that way.
