Ebirah, Horror of the Deep aka Godzilla Vs. the Sea Monster

Taking a break from the city destruction and world saving Godzilla takes a south seas vacation in a film originally written for King Kong. We also have a new director Jun Fukuda, Sadamasa Arikawa taking a more active role in effects, and Masaru Sato does the score.

Invasion of the Astro Monster aka Godzilla Vs Monster Zero

With the sixth entry into the franchise it was decided to mix the sci-fi space invasion theme with daikaiju. The result is a great movie that surprisingly has very little daikaiju screen time, in fact this film has the least amount of Godzilla in the 50's and 60's golden age. But the short screen time is made up for by being some of the best in franchise history.

Ghidorah, The Three Headed Monster

To borrow a term from wrestling, the fifth entry changes Godzilla from the villain, to a tweener. He and Rodan work out their differences across the Japanese countryside. Then Mothra convince them to team up and face the powerful space monster Ghidorah.

Mothra Vs Godzilla aka Godzilla Vs the Thing

The fourth entry into the Godzilla franchise is his last appearance as a pure villain in the original Showa era of films. After hitting box office gold with King Kong Vs Godzilla, Toho decided to pit Godzilla against Mothra who just had her own successful film a few years earlier.
