Super Atragon - Part II (1996)

The Invaders struck first.. Now it's Earth's turn to hit back!

Prepare yourself for the ultimate showdown as the Avatar's subterranean armada strikes hard in their brutal bid to destroy every human on the surface of the Earth! Between Avatar's giant gravitonic rings, each of which carries the crushing force of a captive black hole, and her monstrous microwave emitting battle cylinders, the combined forces of the world's nations don't stand a chance... but Avatar is mistaken in her belief that her forces are unbeatable. Standing against them is a single amazing ship, the Ra, a Yamato-class battle sub secretly rebuilt after its supposed destruction in World War II by a handful of dedicated warriors who now claim allegiance to no country. Joining them are the mysterious Annette, descendant of a lost civilization, and Go Arisaka, the sole survivor of a vanquished UN Peacekeeping Force who must find a way to work with his estranged father, once missing and presumed dead and now the captain of the Ra.
