Petite remarque : avec une taille pareille, Godzilla ne devrait pas avoir le temps de détruire des villes et des armées. Il devrait passer TOUT son temps à bouffer !

Godzilla a intérêt à avoir des muscles en nanofibres de carbone et des os en acier pour ne s'effondrer sous sa propre masse et arriver à se déplacer

So why is Godzilla obtaining ever larger sizes with time? Skyscrapers. Skyscraper height has increased dramatically over the last century. For Godzilla to continue to plow through buildings in major metropolises, a more formidable size is needed. Of course this size change can only be evolutionarily adaptive if it changes the fitness of Godzilla, i.e. in the simplest case the number of offspring passed to the next generation. If Godzilla is able to topple buildings this might allow for greater acquisition of resources in this case food in the form of people. This would increase the lifespan of Godzilla allow for more reproduction or allow for greater amount of energy to be passed to the offspring increasing their rate of survival Or perhaps toppling buildings is a sexual display that sexual partners cue on. Sexual selection!

Of course the real problem of a 55,000 ton Godzilla is the urine production. Using the handy Kaiju post, we can quickly calculate that, 151,436,928 gallons per day. That is about 1.8 of the largest production oil tankers.
