This is a recap film of a show most people have never heard of, made in 1982 when giant robot anime were still finding their voice. It compresses seventeen years of lore into one feature, which means either you're already invested or you're lost in five minutes. If you're watching this now, you're doing it for the historical record of mecha design, not narrative flow.
In 1982, a catastrophic planetary alignment shakes Earth to its core. A mysterious light crashes into the Myojinsho reef, and four more bursts of luminescence scatter across the globe. Seventeen years later, humanity has colonized the solar system and launched an ambitious space exploration program. The elite military unit Crasher stands ready to handle any crisis that emerges from humanity's cosmic expansion. Takeru, a decorated member of Crasher, carries no memory of his origins before the reef incident. What he doesn't know is that he's actually Mars, an alien being sent from the planet Gishin to prevent human advancement into space. As his true identity awakens, Takeru receives a haunting directive: sabotage human civilization and trigger Earth's destruction. Caught between his human identity and his alien nature, Takeru must confront the competing loyalties tearing him apart. The fate of two worlds now rests on which side of himself ultimately wins out. This film compiles the epic struggle between duty and self, duty and conscience, in a race against time.
