Genesis Climber Mospeada

The Earth has been invaded by the mysterious Inbit, and it's up to a handful of survivors from Mars Colony to liberate the planet. After an unsuccessful first attempt to retake the Earth, the inhabitants of Mars Base are ready to try again. Unfortunately, it's been many years since they have been to Earth and they miscalculate both the strength of the enemy and the strength of the Earth forces, with disastrous results. When the Second Liberation force is all but wiped out entering the Earth's atmosphere, the fate of the planet winds up in the hands of a single survivor, Stick Bernard. Joined by a bare handful of resistance fighters born on Earth, Stick must journey to the Inbit's headquarters at Reflex point in an attempt to discover the secrets of the Inbit and find a way to defeat them. Seven young warriors and their transforming planes and motorcycles are all that stand between the Inbit and Earth's freedom in one of the outstanding series that comprised the multi-generational favorite ROBOTECH.
