Dave Meets Godzilla Scene - Dave The Diver Godzilla DLC (4K 60FPS) 

I’d chum the waters on the spot

Except he's contractually forbidden to eat people.

He was seen sleeping when Dave arrived, and he did look a tad bit more sleepy when he awoke…

Heisei ranges from 80-100 meters

it's BioGoji from "Godzilla vs Biollante", who was 80 meters tall.

The smallest Godzilla's are 1954 Godzilla and Godzilla minus 1 both 50 meters and zilla is bigger than both by a couple of inches.

As far as I checked, Godzilla's height is according to the tallest building, according to the era (if a skyscraper is taller than the King, Toho increase its size). Since there's no tall buildings and you can compare Dave with Godzilla's head ("slightly" bigger than him), my idea is that the King of Monsters isn't so big as its other movies, so my head Canon is that it should be at least 50 m, with a maximum of 60 m.

It's final wars so 04
