Japanese anime television series
 is a mecha anime series produced by
Crystal Art Studio (later renamed as Studio Nue) and Tohokushinsha and animated by Soeisha (later renamed as Nippon Sunrise).
It consists of 66 episodes and was originally broadcast on Fuji TV. The first 39 episodes tells the attempted invasion of the earth by Armanoid aliens, while the remaining 27 episodes, with the series retitled "Zero Tester: Save the Earth!" ("Chikyu o Mamotte!"), are about an attack by Gallos aliens.
According to Jonathan Clements and Helen McCarthy's "The Anime Encyclopedia", it was "an early gathering of many of anime's future greats, particularly for the "Gundam" series".
Production.
The first directorial work by Ryosuke Takahashi. In response to the failure of Hazedon in the previous year, the second work of Soeisha changed the project content from marine adventure to science fiction.
"Thunderbird was a Japanese copyright's" Tohokushinsha planning as a concept of "Japanese-made Thunderbird" is, was produced as the No. 2 work of creation Utsusha a subsidiary. In contrast to "Hazedon," which failed in terms of audience rating, this work succeeded in terms of audience rating.
Initially, the Zero Tester was also in a scenario that eventually led to battle in the incident investigation and rescue mission, but the battle color was strengthened by repeated route changes.
At the end of the next announcement, the line "Let's charge this channel again next week" was always included.
The credit for the mechanical design "John Dedowa", is actually a fictitious person. In reality Studio Nue, which was known as Crystal Art Studio at the time, was behind the designs.
