Season 1
When mankind faces an alien force with technology light years ahead of its own, will they be tough enough to save the Earth from destruction? The fate of humanity rests in the hands of the mysterious billionaire Sandman and a young band of orphaned misfits. Sandman's money can build the Gravion, a robotic deity forged of circuits of steel. But can his erstwhile pilots stop fighting amongst themselves long enough to fight the Zeravire? Or will the Earth be lost before the fight has even begun?

Hold onto your seats! With plenty of bouncing breasts, enough merry maids to staff a small hotel, lots of deep, dark secrets and non-stop battles, Gravion has all the fan service, intrigue and outright action that you've been looking for!

Season 2
Hold on to your feather duster! With a legion of perky maids and more fan service than you can shake a stick at, Gravion Zwei has all the action, comedy and madcap adventure you've been looking for!

There's a new player in the game of Earth Defense. Enter the elite G-Soldier Squadron, the first of the government's attempt to mass-produce Gravion technology. Led by ace pilot Faye, will the G-Soldiers push the Earthgertz gang out of a job? While facing a series of stepped up Zeravire attacks, Sandman decides his team needs some time off...at a hot springs resort. What better way to form a cohesive fighting unit than to see everyone in their skivvies? Towels fly and karaoke maids abound as the Gravion team battles a hidden danger deep within a nearby volcano.
