Invincible Superman Zambot 3 (無敵超人ザンボット3, Muteki Choujin Zambot 3) is a mecha anime series developed by Yoshiyuki Tomino and animated by Nippon Sunrise. It aired on Fall 1977 and lasted 23 episodes before concluding on March 25, 1978. It was the first anime to air on Nagoya TV's Saturday 5PM timeslot, which would then succeed to air more of Sunrise's mecha anime shows. The Gaizok arrive on earth, with the sole intent of the total destruction of the planet, but encounter fierce resistance from the "Jin Family", a group of aliens that fled to Earth following the destruction of their home planet by the Gaizok. The Jin family use the power of the combining mecha "Zambot 3" and the "King Beal" spacecraft to combat the Gaizok and the mecha boosts they utilize in their plans for domination.
