Henry G. Saperstein was impressed with the giant octopus scene and requested a giant octopus to appear in "Frankenstein Conquers the World" and "The War of the Gargantuas". The giant octopus appeared in an alternate ending for "Frankenstein Conquers the World" that was intended for overseas markets, but went unused. As a result, the octopus instead appeared in the opening of "The War of the Gargantuas". The film's Godzilla suit was reused for certain scenes in "Mothra vs. Godzilla" The film's Godzilla design also formed the basis for some early merchandise in the U.S. in the 1960s, such as a model kit by Aurora Plastics Corporation, and a board game by Ideal Toys. This game was released alongside a King Kong game in 1963 to coincide with the U.S. theatrical release of the film. The film's King Kong suit was recycled and altered for the second episode of "Ultra Q" and the water scenes for "King Kong Escapes". Scenes of the film's giant octopus attack were recycled for the 23rd episode of "Ultra Q".
