What does Godzilla eat?
A. Before being mutated by nuclear testing, the dinosaur that would become Godzilla was apparently a carnivore. Probably eating such game as was available on the remote South Pacific islands and surrounding seas. Once mutated into Godzilla, the creature’s body adapted to metabolize energy from radioactive materials. It has been implied that he sometimes actually eats radioactive materials, but we’ve never really seen him do this in the films. Mere exposure to high radiation nourishes him, and his attacks on nuclear installations may just be to release radiation for him to absorb. The Baby Godzilla seen in the Heisei films ate plants as a hatchling. This does not necessarily mean that he was a herbivore. Dogs and cats sometimes munch plant matter despite being carnivores. Eating was apparently a vestigial instinct for this creature anyway, as his later growth and development was attributed to absorbing radiation. The American “Godzilla” ate fish.
