Godzilla vs. Hedorah

By this time Godzilla, now the defender of the Earth, has become a national phenomenon just like the Loch Ness Monster in Scotland and, especially with children, ingrained into the Japanese consciousness. However, the Japanese still do not realize that destroying Earth will summon the millennia-old protector. A young boy finds a dangerous alien monster feeding on pollution that he names Hedorah, a pun on "hedoro", the Japanese word for pollution. In his dreams, he wishes for Godzilla to destroy Hedorah and, hopefully, persuade people to stop polluting Earth. Godzilla, coincidentally, fights the monster because of the destruction of the environment.
