The Intergalactic Defense Force on the water planet of Aquatica is attacked by a giant mechanical Sea Dragon. It swiftly demolishes a fleet of Robot planes from Ursa Minor, as well as the Tigers from Andromeda before G-Force is even assembled to blast off from Earth. When even the fiery Phoenix proves no match for the Sea Dragon, G-Force has to retreat, but returns with a repaired Phoenix and a new freeze weapon developed by 7-Zark-7.
