Battle Of The Planets G-Force ( Attack Of The Space Terrapin ) Full Cartoon 1978

The opening episode in the series introduces us to G-Force - 5 orphans enlisted to defend the Earth against enemies from the hostile world of Spectra. The first attack comes in the form of the space terrapin - a giant, turtle-like machine heavily armed and able to crush Earth's air & sea defences. G-Force is called in to deal with it, as the sinister Zoltar & the terrapin's C.O., Commander Gorak, attack Earth's shipping lanes and try to steal a substance known as VitaLumen. When G-Force members steal aboard the Terrapin, they find themselves in trouble when they are cornered by Spectran soldiers.
