Godzilla vs. Gigan
The Nebula M aliens, a race of cockroach-like aliens from a doomed planet, decided to colonize Earth and sent Gigan and King Ghidorah to wipe out mankind. Gigan and King Ghidorah targetted Japan and ravaged the city, destroying everything in sight. The military was sent in but proved useless against the two monsters. Fortunately, Godzilla suspected something was wrong and sent Anguirus to see what was happening. The military, not knowing Aguirus' intentions, drove him off. Anguirus told Godzilla and the two swam to Japan. They saw what Gigan and King Ghidorah were doing to the city and challenged them. Gigan and Ghidorah proved tough foes, with Gigan even causing Godzilla to bleed. This was further complicated by the Nebulans using a cannon to fire at Godzilla and Anguirus. However, the humans fought back and destroyed the tower and Godzilla and Anguirus prevailed, sending Gigana and King Ghidorah into a retreat.
