Godzilla vs Monster Zero divx eng (1965)

The plot involves the discovery of the mysterious Planet X in our solar system, leading to a joint U.S./Japanese space exploratory mission. The explorers bump into some aliens with no fashion sense whatsoever (even for 1965), who claim their planet has been under constant attack from the powerful Monster Zero -- also known to Godzilla fans as Ghidrah, the three-headed monster from the previous year. The aliens suggest a deal with the Earthlings: if they can "borrow" Godzilla and Rodan to help rid their planet of Ghidrah, they will cure all of humankind's diseases in return. Of course, this is actually an elaborate ruse to rid the Earth of its monstrous defenders, leaving it vulnerable to invasion.
