In 1999, a massive colony ship carrying roughly two million Iderians — a race that lost its homeworld and wandered space for over ten thousand years — enters the solar system. Running low on energy and knowing Earth is already inhabited, they launch an invasion anyway. Earth Defense Force is initially forced to retreat against the technological gap, until Colonel Yōichi Takashiro, who alone predicted the attack, arms three pilots with his prototype Variable Machines to form the Special Armored Battalion Dorvack.

— LEGACY —
Historical Position
Ashi Productions' first entry into the real robot genre, produced as a replacement for the studio's cancelled project "Mad Machine"
Genre Innovation
Grounded its robots and enemy mecha in realistic, contemporary military vehicle design rather than fantastical super robot aesthetics, a choice contemporary reviewers highlighted as a defining strength of the series
Relationship to Previous Mecha
Part of the same crowded 1983 wave of real robot anime as Dunbine, VOTOMS, and Sasuraiger, distinguishing itself through its military-grounded, vehicle-based transformation designs
Industry Impact
Launched the mecha design career of Nobuyoshi Habara, who went on to direct Fafner in the Azure and Space Battleship Yamato 2202
International Recognition
Primarily remembered within Japan; later reissued on Blu-ray as part of the "Memorial Anime Library" classic anime preservation series, and received a MODEROID plastic model kit from Good Smile Company decades after broadcast
