I might as well also bring up this, why does Berukyurosu change into Doragyurosu and why does it need the Dragon Element as Doragyurosu?

For the Dragon Element, since the Stygian Zinogre uses Dragon to both keep it warm and cool in some areas, I'm guessing Doragyurosu uses it for a similar reason.
