Fifty years after he first attacked Tokyo, Godzilla is back on the rampage — and this time he's brought reinforcements — in this monster opus from Toho Studios. After numerous rounds of combat with Japan's most furious monsters, the robotic beast Mechagodzilla is in for some much needed repairs when a handful of sprites appear before the scientists putting the machine back in fighting shape. The enchanted ones warn the scientists that their actions could have grave consequences, but it isn't long before a strange series of natural disasters brings the most fearsome of all monsters, Godzilla, back to life. What's more, Godzilla is joined by Mothra for a reign of terror that threatens to devastate the island. With few alternatives, Japan's leaders pit the repaired Mechagodzilla against Godzilla and Mothra, but it quickly becomes unclear if the robot will obey its human creators or join forces with the flesh-and-blood monsters. — Mark Deming
