Cantios looks just like an average Flying Wyvern, with (at first look) no special features. But as soon as he starts fighting you, e reveals his true power. The Cantios found in the Belurius Region look different than those found in any other regions, because they are sort of a subspecies of the regular Cantios. Because of this, those special Cantios have found new ways to use the Undrea, performing new, strong attacks.
