The term kaiju means "strange beast" and is most commonly used to refer to Japanese media revolving around giant monsters of unimaginable power. When people think "Kaiju" most think of Godzilla, King Kong, and Ultraman, all of which have an element of goofiness to their franchises. However, there is a distinct element of horror to the concept of these unstoppable forces of nature being able to destroy cities with no possible way of stopping them.
