"A plan to rid our world of King Ghidorah backfires and the Earth faces certain calamity! A small piece of technology from another world may be the only hope of salvation."
SPOILER WARNING: This section may contain major plot and/or ending details. Proceed at your own discretion.
Godzilla and King Ghidorah are battling in Washington D.C. While their conflict rages, Dr. Talbert, Ridley, Yamada and Weinstein are observing from a laboratory. As Yamada and Weinstein discuss the ethics behind the portal Yamada's company constructed, Ridley informs Talbert of a new plan to combat the monsters. Back in D.C., Godzilla gains the upper hand against King Ghidorah and seemingly defeats the beast with a blast of his atomic breath. As Godzilla walks away, King Ghidorah rises back to his feet and kicks Godzilla in the back. King Ghidorah then takes flight and grabs Godzilla with his feet, flying out over the open ocean. Seeing an opportunity, Weinstein contacts an aircraft carrier and recommends a nuclear strike against the monsters while they are over the open ocean. Talbert expresses his doubt that the plan will work and tells Ridley to prepare to activate her backup plan. The president approves the strike and two fighter jets armed with nuclear missiles are launched from the carrier. The jets approach Godzilla and King Ghidorah and unleash their payload of missiles, causing both monsters to vanish in a nuclear explosion. As the smoke clears, the water stirs and Godzilla surfaces once again, completely unharmed, while King Ghidorah is nowhere to be seen. As Godzilla wades back to shore, a helicopter is deployed to lure him away. Godzilla fires his atomic breath at the chopper and misses, then simply destroys it with a swipe of his hand. As Talbert and Weinstein panic to decide what measures to take next, Ridley dons a suit with motion controllers attached to it and informs them about her backup plan. Ridely states that she recovered metal from the robot Godzilla found in the other dimension and replicated it to build and army of "MechaGodzillas," as she dubs them. Weinstein protests the operation, but Talbert states there is no other option and tells Ridley to unleash the robots. As the MechaGodzillas fly out of a hangar, Talbert and Yamada watch on a computer screen and both state they hope this works.
