Before the upcoming Godzilla x Kong movie, it’s time to finally answer the question: what type of fiction are kaiju? Are they soft sci-fi of a fairy tale tier, or can we expect them in serious hard science fiction as well - and maybe even behind our windows?
So, to answer that, I have made up a basic classification of kaiju morphology, and compared them with known megafauna, such as elephants, blue whales and sauropods like Argentinosaurus, as well as delved a bit into giant ecology. Join me in this exploration, it's gonna be curious!
