The Godzilla Power Hour was a Japanese animated television series/Saturday morning cartoon, originally aired in 1978 on the NBC television network. In Japan, it was released in 1977. Produced by Hanna-Barbera Productions, the series was an animated adaption of the Japanese Godzilla films produced by Toho. Airing alongside Jana of the Jungle, hence the “power hour” aspect of the title, the series continued to air until 1981, for a time airing solo as The Godzilla Show, until its cancellation. In Japan, it was simply called Godzilla. Toho helped with the series production, they even did the animation for it and the monster concepts.
Godzilla vs. Destoroyah (ゴジラvsデストãƒã‚¤ã‚¢, Gojira tai Desutoroia), is a film where Godzilla fights Destoroyah, a creature that was created by the Oxygen Destroyer weapon that killed Godzilla back in 1954. It was released in Japan on December 9, 1995. It was originally intended to be the last Godzilla film until 2004, but due to the worldwide fan-disappointment of the 1998 American Godzilla film, Toho decided to release a film in 1999.
