Controller of Planet X (Godzilla vs. Monster Zero)

The Showa iteration of the Controller is a character in the 1965 godzilla film Invasion of the Astro-Monster.

Overview
The Controller is the mysterious leader of Planet X. He lures an astronaut from earth into his office in order to "seek his assistance" in "neutralizing" Monster Zero, but in reality he simply wants earth's prime defense force of Godzilla and Rodan out of the picture so that he can send Ghidorah, who is really in his control, to earth in order to overtake it for unknown reasons. He proposes to have a miracle drug to cure all earth diseases, but this was likely a ruse.
