Ro-Man, a robot monster dressed in gorilla suit and diving helmet.
Came to earth with help from “The Great One”.
From his headquarters in a Bronson Canyon cave, he communicates with “The Great One” via World War II surplus radio gear and a Lawrence Welk-style bubble machine. Though its cosmic death ray Ro-Man caused untold destruction and has destroyed all of humanity with the exception of a small band of survivors.
Initial reviews were so bad that the director Phil Tucker attempted suicide.
