NOVA Mecha
The first NOVA defence vehicles were modified transport and construction vessels. The Lunajumper was basically a space shuttle with a mounted beam cannon and demolition grenades.
NOVA's first headquarters was a moonbase named Camerotta. Lunajumpers were launched from separate domes. When Camerotta is destroyed rather early in the series, NOVA is relocated to the much larger and better defended King Camerotta Base, a futuristic castle-like structure with an actual ramp that folds down like a bridge over a moat! From this ramp are launched the Skatestingers, of which there are three, and the heavier VoltaVokka. The Skatestingers can attach to the VottaVokka in extreme situations and create a walking mecha known as MegaVolta.
There is also a large burrowing mecha called Luna Garuba and a humongous transport vessel (that can carry everything) named GranEnteros.
NOVA was initially designed for lunar and orbital missions only, but the need to operate on Earth became more apparent. Each of the vehicles and mecha have an Atmosphere mode, so that they can be used on Earth.
