Personality
Godzilla is a very intelligent creature and more smarter than other creatures. Godzilla greatly hates humans. During his conversation with Mothra, which was translated by the Shobijin, Godzilla explains the reason he hates humans because they're always attacking him. However, Godzilla would put his hatred of humanity aside and join forces to defeat a common enemy.

Origin
Godzilla and the rest of his kind are members of a species of dinosaur called Godzillasaurus, that survived the extinction of the dinosaurs at the end of the Cretaceous Period. At some point after WWII, a Godzillasaurus living on Lagos Island, was mutated by nuclear fallout from the H-Bomb.
