Plot
On the planet Zarcadia, discovered by 7-Zark-7, a series of mysterious plane accidents are occurring. There is no mention of turbulence - only 'something white', according to Chief Anderson. When G-Force reaches Zarcadia Mark encounters a titanic mummy - apparently powered by a highly radioactive element called 'Plutonium X', manufactured only by Spectra. The only antidote, something called Anti-Pluton, is in the hands of its creator, a Dr. Sweet, who resides on the planet. His nephew, Buddy, is the son of one of the missing pilots. When his dad apparently returns, he is caught searching Dr. Sweet's safe. The man is none other than Zoltar, and later that night the mummy attacks the airport. G-Force must find a way to eliminate the mummy before it can destroy Zarcadia - and them.
