Dino Mech Gaiking contains episodes 1-44 of the anime directed by Tomoharu Katsumata in standard definition on a Blu-ray disc.

Thousands of years ago, the people of the planet Zela uplifted the cultures of Earth with advanced alien science and technology. Now, with Zela itself in danger of being dragged into a black hole, the supercomputer Emperor Darius wants to find salvation for his people... by taking our planet for himself! The only ones who can stop Darius’ total conquest are the carrier superweapon Daiku Maryu and its intrepid but eclectic crew: an American navy pilot, a sumo wrestler, a kickboxing champion, and a host of other psychic misfits. The newest addition to the team is a brash baseball player named Sanshiro Tsuwabuki, whose arm was damaged in a Zelan attack, and now seeks revenge at the helm of the giant super robot Gaiking! With a rooting in contemporary science and pop theories about aliens influencing ancient civilizations, Gaiking is a show that will appeal both to robot fanatics and fans of classic science fiction. This complete collection includes all 44 episodes in standard definition. With the original Japanese language, and English subtitles!
