Ultraman's Evolution Chart
The original Ultraman was nothing more than a small animal that crawled around making a high-pitched cry of "Deyaa! Deyaaa!!" (Though from the perspective of us humans, he was still huge...)
Of course, he couldn't use advanced techniques like the Specium Ray. Instead, he shot a gel-like Specium gland fluid from a scent gland near his anus, and repelled predators with its pungent smell.
It took a full 80 quadrillion years for Ultraman to take on the form we know today...he was a galactic myth.
