Talk:Master Ceadeus 27 Rathian and Rathalos Subs Theory/@comment-4212769-20140626100123/@comment-4212769-20140703111224

You can be as stubborn as you want, that doesn't change that the hormone change is caused by a mutation of any sort, so a mutation is all the ways' reason.

For age, I have to say, there has to be something that causes the color change like mating season (like in one of my theories) or losing fertility (in my theory as well). There's no reason to turn into a more beautiful and conspicuous version of himself (changing habitat would be a mutation). Mating season is the most senseful idea for Azure/Pink, but there's one problem (I bypassed with a little something) that normal Rathians and Rathalos are seen together.

In the end there are two ways: My theory (as arrogant as this may sound) and mutation.
