Sometime after the events of Catastrophe, the Invid finally appear on Earth and conquer the planet despite meager resistance by the surviving Southern Cross forces. Over a decade later, the Robotech Expeditionary Force's (REF) Mars Division is sent to Earth to try attacking Reflex Point, the Invid's main hive, in North America, but the entire fleet is annihilated by Invid forces. The debacle's only survivor, Scott Bernard, crashes somewhere in South America and begins a long journey to Reflex Point in his Cyclone motorcycle. A survivalist named Rand joins him after he is saved by Scott from Invid Shocktroopers while scavenging a crashed Mars Division Horizon-class shuttle.
