King Ghidorah
Anguirus reports back to Monster Island, and Godzilla follows him back to Japan to save the Earth from Gigan and King Ghidorah. The aliens attempt to kill Godzilla with a lethal laser cannon hidden inside Godzilla Tower, but Gengo and his companions use the aliens' over-reliance on technology against them, forcing the invaders to unwittingly destroy themselves. After a lengthy fight, Godzilla and Anguirus force Gigan and King Ghidorah back into space and then Godzilla and Anguirus swim back to Monster Island, but not before Godzilla turns around and gives a roar of triumph, in thanks to his human friends.
