The good thing in the battle scene of twinrova OoT is you absorb their elemental powers using the Mirror Shield. but after that battle the Shield cant absorb any other attacks from different enemies like ganondorf's lightning.
Volvagia is hard headed, it requires a megaton hammer to knock him/she down. I doubt volvagia had parents "he/she not listening to them" that's why the head of this dragon is hard headed :D
