Encyclopedia Entry:
Godzillas are a race of bold,ferocious and extremely powerful kaiju that originated from the Gihirios region,and live in the oceans,and mountains.

Godzillas are a force of nature,and help balance life and death. Though they cause destruction,they don't do it for a malicious intent,they do it to protect people,usually humans or other monsters,as most kaiju are extremely aggressive and have been known to kill people.

Godzillas are tanks of power,And though they are weaker than cosmic entities,their variant species,Garthzill can rival them in power. They have the ability to shoot blasts of plasma and radiation from their mouths. They have another Bailey in which they heat up their body and blast hellfire hat can burn almost everything and anything.

They have been titled "Queen of monsters" from their god-like powers.
They were so powerful that demon lord couldn't permanently change their height,so she gave them the ability to change their height instead.

Their habitat are the ocean,and mountainous areas because,whoever can swim the farthest,or climb the biggest mountain,are usually the ideal person who mate with. They do this because they hope to have stronger offspring,because in a region where a lot of things are hostile,it would make sense for them to try to have the strongest offspring as possible to ensure the survival of the next generation.

When they find a man that either climbed a giant mountain,or dove into the deepest waters,they will grab them (via mouth or arms or tail) go to an area that is safe,and rapes them there.
After the whole "thing" they wrap their grabs or tail around their partners so they are immobile and trapped,so their new husbands can't escape.

Even though they are extremely powerful,they aren't really that prideful. But they are dominant,and will force their husbands to be submissive,but not in a aggressive way,more of a playful way.
The cause of this is most likely hormones of aggression. But in a playful manner so that their husbands cannot be harmed.
Despite them being giant monsters,they are oddly warm and affectionate towards their partners.

Addendum:
The plates on their backs and tails are the source to their great power. They also use their plates for three another functions,cooling off,food,and battling.
They can use their plates to reflect the sun's heat,absorb radiation from the sun and convert it into chemical energy that,through cellular respiration can fuel their metabolic activities. [So they are plants,but more advanced,and powerful]
They can also use their plates as a defense mechanism for the other kaiju that can possibly pose a threat to them.

Their plates often glow when they are using their powers,when they are signaling something,or intimidation.
