Drago (original version: Nova Dragon) is Dan Kuso's Guardian Bakugan and the Bakugan main protagonist of the Bakugan Battle Brawlers anime series. He serves as both a battle partner, a guardian, and source of wisdom. Although he is impatient and is a pacifist, he wants to help Dan protect Earth and Vestroia. He is the direct descendant of the original Dragonoid, one of the two first Bakugan ever created. He is one of the most powerful species living in Vestroia, able to infinitely evolve on his own. In battle, his power is to radiate intense heat from his body, dissolving everything around him.
