Invincible Super Man Zambot 3 (無敵超人ザンボット3, Muteki Chōjin Zanbotto Surī) is a super robot anime series created by Yoshiyuki Tomino and Yoshitake Suzuki, featuring character design by Yoshikazu Yasuhiko.
The series focuses on the survivors of planet Beal, which was wiped out by a mysterious entity known as Gaizok.
The few remaining survivors escaped to Earth and split into three families, named Jin, Kamie, and Kamikita.
While attempting to start a new life, the Jin family prepared for a Gaizok invasion of Earth by building three vehicles which when combined form the super robot Zambot 3.
[1] While defending against Gaizok attacks, the Jin family also face harsh criticisms from the people they protect, who blame them for causing the invasion.
