Time For Some Fan Explanations!

I read this theory the other day and I thought it was appropriate. It gives a logical explanation of Kaiju.

I hope this counts.

I believe Godzilla could survive the square-cube law if his bones and skin were stong enough. I'm not sure if that's correct though since science isn't a strong field of mine.

Godzilla does need to eat but he feeds off of radiation. And you know how many nukes are being stored in the world right now.

If Godzilla had an extra heart, it's possible he could circulate blood fast enough through his body.

The atomic breath is created through multiple glands near the neck, one gland creates the laser while another provides the blue flame found emitting from his laser in the movie.

A kaiju could be possible if they are a Silicon-based lifeform.  The kaiju in Pacific Rim are Silicon-based and they can get huge without weighing very much.  Look at Slattern the Cat. 5, it stands at 596 ft. tall and only weighs 6,750 tons (Estimated).  Now Godzilla could exsist if he is a mix of both Carbon and Silicone based lifeforms.  His bones and muscles could be silicone-based, while his skin and everything else is carbon-based.  It's a theroy, not sure if its god, but oh well.
