How many Godzilla's could Earth have supported at one time?

i dont really think the mutos exsisted during godzilla's time, i am still spectacul about them being from outer space, however for the support of the world holding many godzilla's....ummm i would say at least maybe a few hundred exsisted during this periodic time, and that they all lived and ruled the world for millions of years. i really dont know just a theory of mine i guess.

Well in my G-series Doujinshi manga storyboard, The Kaiju's are classified by breeds meaning they are they're own species not just one of each.

The Godzilla breed is named Gojirasaur here and they've got plenty, although only 20 are from the "royal family"(king of monsters) (they're the alpha's) and only those 20 have left the Monster Islands, so they we're classified by the order in which they appeared. 14 Gojira's and 6 Godzilla's. The main Gojirasaur is Godzilla III, the 1970's Gojirasaur is Gojira VII and the new one from 2014 is Gojira XIV, one of the oldest of the species (exlaining his massive size)

bout 3 or 4

Got any pics, @Xengi?

The Godzillas have to be a freak mutation. Even if they only survived off of the earths radiation they're so territorial they would annhilate the planet, plus scientists would find their bones and everyone would be in awe that something that big existed. I'm guessing only a handful existed. Also keep in mind that the nuke "changed him". It's vague but Godzilla could have been much smaller.

I totally agree with you NPinkham19. Godzilla's initial size, compared to the Muto, is WAY off. Godzilla could easily squash that muto with his foot, so just how could they be natural enemies from millions of years ago? I'm pretty sure their species was at some point smaller, so it would make sense that they would be natural enemies of the Muto. I think maybe all that radiation testing, or the attack by the navy on Godzilla probably mutated him, so instead of killing him, they just made him worse.  This is all pure speculation, but it's most likely that it'll follow something like this. Besides, the whole Muto theory from outer-space seems kind of too far out for this kind of movie. They've already established that this is going to delve deeper into how humanity should be punished for messing with the earth, adding aliens to this would just make it weird and out of place. I could be mistaken though.

I'd say the Godzilla species diminished in overall population as they grew larger and more heavily mutated with each generation, with these changes being beneficial to each individual creature, but not the species at large. Territorial disputes over radiation sources would grow between respective giant species, and the Mutos likely were the parasite that made things even worse, thus sparking a mass species rivalry compounded by the KT-event, which made things scarce and killed off several of these giant creatures, but also allowed the strongest of all other respective post-evolutionary mega-fauna to become even stronger to the point of the modern-day.

Well, that's my two-cents anyways.
