MemberMothra LarvaeMay 11, 20141967 Views6 RepliesOver the many years of Godzilla's film "career," we've seen many kaiju come and go, win and lose, each with their own unique and memerable designs, however, there is one thing that I have noticed that many of them have in common;
The majority of Godzilla's foes have been insectoid/crustecean/arachnoid (multi-limbed and/or exoskeleton) in appearance (in one form/way or another)-
Kumonga
Kamacuras
Megalon
Mothra
Battra
Ebirah
Destoroyah
Megaguirus
Meganulon
Flying M.U.T.O. (Hokmuto)
8-Legged M.U.T.O. (Femuto)
Yes, they are just movies and could be coincidence, but this could say something about Godzilla's natural diet. Yes, Godzilla was supposed to original appear with a cow in his mouth, and in one movie he was meant to be shown eating another kaiju (Godzilla Jr. had eaten whales in GvD), however, these are after his mutation(s); perhaps he had once been an insectivore?
I'd like to hear what you guys think about this.
