The company describes the anime:
As their first step toward the conquest of the Crescent Galaxy, the robotic armies of Mardoul have centered their malevolent mechanical designs on the invasion of the seemingly medieval colony world of Earst. Their expected easy victory against mere knights in shining armor, however, is shattered when Prince Joldy Volder confronts them in a secret weapon that has lain in Earst's hidden underground bunkers for millennia: the legendary giant robot Galient! Myth and motorized mayhem collide as the acclaimed creator of Armored Trooper Votoms, Ryousuke Takahashi, orchestrates the wildest heavy metal mecha fantasy ever with PANZER WORLD GALIENT!
Panzer World Galient aired for 25 episodes in 1984 to 1985. A separate three-episode Panzer World Galient OAV released in 1986.
Ryousuke Takahashi directed the series at Nippon Sunrise. Sōji Yoshikawa oversaw the series scripts, Norio Shioyama was the character designer and chief animation director, and Tōru Fuyuki composed the music.
Sentai Filmworks will also release Outbreak Company, The Dreaming Boy Is a Realist, The Most Heretical Last Boss Queen: From Villainess to Savior, Ninja Scroll, and Level 1 Demon Lord and One Room Hero anime on home video in October.
