He is a gigantic dragon-like Bakugan from "Pyrus": a space attributed to fire. 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 heat from his body, dissolving everything around him and negating card abilities. He is the leader of the Bakugan; a true knight with strong convictions and deep friendship with Dan. During Shuji's Bakugan rematch against Dan in episode 1, Drago emerged from the playing field and joined Dan. Unlike other bakugan creatures, it is capable of breaking the effect of cards. He evolves into Delta Dragonoid in episode 22, with metal plated armor, a trident-shaped tail and enormous wings. Drago evolves again in episode 37 where he becomes Ultima Dragonoid.

Preyas has the ability to change his molecular structure, due to his peculiar nucleus, to take on the characteristics of all the attributes: Pyrus, Subterra, Haos, Darkus, Aquos and Ventus. In contrast to his appearance, he has a very quirky sense of humour. He's completely dedicated to Marucho. He joined Marucho 6 months after it had appeared on Earth and eventually entered Marucho's new home in Episode 7. He can't evolve but he lays a egg in episode 30 that hatches into Angel/Diablo Preyas.

Gorem has an enormous shield that it uses to defend and weaken attacking bakugan. Like Drago, Subterra Gorem can also evolve. Gorem appeared in Julie's bedroom in episode 10 after she had tried to find her talking Bakugan in Bakugan Valley and failed. Gorem evolves into Hammer Gorem during episode 29.

Darkus Hydranoid (ダークオン・ヒュドラ)/Darkon Hydra: Hydranoid is Masquerade's loyal Bakugan, a dragon creature with a very strong armour, revolting face and a sharp flail for a tail.

Though his mobility in battle is slow, he's mercilessly cruel and unforgiving. He later in episode 26 evolved into Delta Hydranoid, now bipedal with improved armor and a second head.
