Defenders of the Earth - Season 1 - Eps 16: The Men of Frost
For Ming's plan to blanket the earth with a veneer of frost to be successful, the satellite requires the strength of a Starblue Crystal, of which only three exist. During a ceremony in which Mandrake donates his Starblue Crystal to the Central City Museum, the Defenders fight off an invasion by Ming's forces and capture two of his Men of Frost, Elgar and Zikry. Rick makes good use of a new invention which re-humanizes Men of Frost and Elgar tells the Defenders of Ming's plan to conquer earth. Zikry however, remains loyal to Ming and sabotages Dynak X before our heroes discover his true "evil" side. When Ming locates the last remaining Starblue Crystal he launches the satellite. It appears that it may be too late to stop Ming, but the Defenders fly out in their battle ships, engage Ming's roboships in an outer-space dog-fight, and explode the satellite with seconds to spare.
