I guess Hegel’s probably used because he is associated with the term “zeitgeist”? Basically Godzilla is a big cultural phenomenon because the films reflect wider contemporary social intellectual contexts/“spirit of the times”, and not just because of “innate” qualities. The comic doesn’t appear to engage any further with Hegelian philosophy, but I can see some connection with Hegel, and thinking about zeitgeist seems like a decent entry point to further dialectical investigation about pop culture.
