how would you make the Hokmuto

According to the toy boxes, the mutos are prehistoric rivals of the Godzilla creatures.

I'm not a fan of the 'crazy scientist man' idea. It's a little too...hokey for me.

But how would you make them

well, when a daddy hokmuto and a mommy hokmuto love each other very much...

LOL^ YESS

I thought that Rodan delivered baby kaiju since the stork is too small.

what about the labratory ? 

Sugar, spice and everything nice! These were the ingredients chosen to make the perfict little hokmuto's! But professor untonim accidentally added an extra ingredient, CHEMICAL X

Well, according to me:

The Hokmuto, a creature that evolved in a similar fashion as the creature known as "Gojira", by means of a nuclear environment causing mutations and adaptations to said mutations to compensate, eventually resulting in immense size and durability not possible by normal evolution, exotic abilities only constituted by a nuclear internal body plan, and effectively unlimited longevity, thus making it, its species, and other species that evolved in such an era, living gods. All creatures with such an origin are colloquially known as Post-Evolutionary Ultra-Fauna, or PEUFs. There is a scale for such creatures, with four main levels:

Immortal Class - the creature is relatively small, at around 10-40 meters in height, and posses little to no exotic abilities, and is only slightly more durable than other normally evolved creatures of similar size, but often show up in enormous quantities

Deity Class - the creature is moderately sized, at around 40-80 meters in height, possessing high durability, an average set of exotic abilities,  and is the most commonly described class of PEUF

God Class - the creature is very large, at around 90-160 meters in height, possesses extreme durability, and a greatly variable set of exotic abilities, offset by their lower appearance rate

Kaiju Class - the creature is unimaginably large, beyond 170 meters in height, is virtually indestructible, can bend the very laws of physics around it, and have only been recorded in a few case instances
