"Drago (Pyrus Dragonoid)"

Voiced by: Keiji Fujiwara^[1] (Japanese); Jason Deline, Brian Sommer (Defenders of the Core)^[2] (English)

The main protagonist (alongside Dan) and also Dan's partner who resembles a dragon. Drago is the leader of the Bakugan with strong convictions and morals, and is arguably the most powerful of all the bakugan. Together with Dan, they set out to defeat the Doom Beings, and rebuild the Perfect Core of Vestroia. He has the ability to radiate intense heat in battle dissolving everything around him. He is equipped with high intelligence. He is limited in battle mobility, but compensates for it through powerful strikes. He is able to infinitely evolve on his own and with every evolution it makes him stronger and it brings him one step closer to the Perfect Core.

• Delta Dragonoid

Drago's first evolution during Dan, Runo, and Marucho's battle against Julio, Klaus, and Chan Lee in Drago's On Fire. He fought against Dual Hydranoid, and lost, sending him to the Doom Dimension. In the Doom Dimension he battled Apollonir, after defeating him, he had to defeat Shun, Julie, Runo, and Marucho. He has three sleek horns and a hard plated armor in ball mode with chrome rings. He has an extra set of wings and a pitchfork tail.

• Ultimate Dragonoid

Drago's second evolution when he defeated Storm Skyress. He has markings on his wings, which are now split, and he also has two horns that are merged. He was also used to defeat Alpha Hydranoid.

• Infinity Dragonoid

Drago's third evolution (as an ultimate Bakugan) when he absorbed the Infinity Core from Wavern. He used it to absorb the Silent Core from Naga, becoming the Perfect Dragonoid completely, and later transforming himself into Vestroia's core.

• Neo Dragonoid

Drago's regeneration in New Vestroia, after the Ancient Soldiers separated him from the Perfect Core in Invasion of the Vestals. Although he is weaker than his previous form, he still is one of the strongest bakugan. He still has a connection to the Core, and can gain new abilities from it during emergencies. When Dan lost his battle to Spectra and Helios, he also lost Drago and because of his forced defection, his color change from a pure red to mixture of red and black (turning him into a dark and corrupted Hex Dragonoid). Drago has now also lost all his free will in this form and his pupils have been erased. Drago gained the ability to change into any chosen attribute at the cost of his physical health. NOTE: As Drago has a portion from Vestroia's Core, he can evolve more of four times than in the first season.

• Cross Dragonoid

Drago's next evolution when he inherits the Pyrus attribute energy from Apollonir in Six Degrees of Destruction, sadly Apollonir died. He lost the Pyrus energy when he, Helios, and Wilda lost a battle against Farbros and Dryoid.

• Helix Dragonoid

Drago's next evolution when he absorbed the 6 Attribute energies from the BT System in Exodus. This evolution also marks the first anthropomorphic design of Drago. He can now combine with Battle Gear (JetKor), and his Dragon Hummer abilities gives him super speed. His Battle Gear is JetKor, a dual cannon blaster which can shoot an energy blast and defeat opponents. A lock on beam from the green lens freezes the opponent before the blaster attacks. It combines the two blaster beams into one enormous blast. It was used by Dan to combine with Drago in Fusion Confusion. The finished version was shown in episode 46. Unlike Helios' Battle Gear, it was made using Drago's own DNA so that it'd be more organic in nature, due to Drago's hatred of mechanical Bakugan and not wanting to become a cyborg like Helios. Because of this, JetKor acts like a part of Drago's own body when he uses it.

• Lumino Dragonoid

Drago's next evolution in Gundalian Invaders. He evolved in, when Neo Ziperator gave him the Element in The Element. He has four wings and a tail with a giant X shape on it. Curiously his body looks like an amalgamation between his previous forms Cross and Helix. This marks the quickest time Drago has evolved in any of the series. His second Battle Gear is Explosix Gear (Cross Buster), similar to the JetKor with the only differences being the appearance of the cannons and its expansion to cover Drago's new wings. From this on, he also started to use two Mobile Assault Vehicles: Raytheus, a large motorcycle like hover vehicle with a laser mounted in front, and Jakalier, a resemblance to the ocelot's glider with the only difference being Dan being able to ride inside of it.

• Blitz Dragonoid

Drago's next evolution when Dragonoid Colossus evolves him as a reward for defeating him in Genesis. He now has armor covering his front body and has a set of wings again, but bigger than his previous version's wing, Lumino Dragonoid. He is also able to combine with Dragonoid Colossus respectively. His third Battle is Axator Gear, given from Dragonoid Collossus. In this form, he represents the original Dragonoid who banished the Nonets to the Doom Dimension.

• Titanium Dragonoid

Drago's next evolution, when Code Eve rewarded him for defeating Barodius and Dharak in Destiny Revealed. His Mechtogan is Zenthon and his Mechtogan Titan is Zenthon Titan. His BakuNano is Sonicannon, while his Mobile Assault Vehicles are the motorbike Zoompha and surfboard-like Rapilator. He gave some of Code Eve's power to the other Brawlers to summon their Mechtogan.

• Fusion Dragonoid

After connect the power of the Gate and Key, Drago evolved again to a "Baku Sky Raider" of himself. His razor sharp wings and infamous horn give him tenacious attack when he leaps into battle. Only the bravest opponents can measure up to the combined ruthlesness and courage of Fusion Dragonoid. Fused with Reptak, he becomes Aeroblitz. His Battle Suit is Defendtrix.

• Maxus Dragonoid / Maxus Cross Dragonoid

Neo Dragonoid's / Cross Dragonoid's transformation when combined with the six mechanical Bakugan Traps Brachium, Grafias, Dark Hound, Grakas Hound, Spitarm, and Spyderfencer.

Preyas is a chameleon-like Bakugan with strong loyalty to Marucho. His greatest strength is that Preyas can change his molecular structure allowing him to turn to Darkus or Subterra.

It is completely controlled by Masquerade and obeys all of Masquerade's commands. This one-headed Hydra-like Bakugan has very strong armor, a dragon-like face, spines all over its body, and a sharp flail for a tail. Its mobility is extremely slow, but can battle all species with its extremely powerful and forceful strikes. Hydranoid is a mercilessly cruel and unforgiving monster, not to mention extremely violent and arrogant that feeds off the power of Bakugan sent to the Doom Dimension by Masqerade. Like his old nemesis (now close friend) Drago, Hydranoid can evolve into a more powerful monster.

• Dual Hydranoid

Hydranoid's first evolution with two heads. Hydranoid now also has two tails. He seems to be partially mechanical even though his evolution was completely natural, unlike Helios who was evolved by Vestal Technology. His arrogant, merciless personality is unchanged.

• Alpha Hydranoid

Hydranoid's second evolution with three heads. Even more of his body looks mechanical, and he now has three pairs of wings. The armor on the front of his body can rotate like a huge grinder after he ensnares his opponent with metal cords that erupt from chinks in his wings (this is probably a strange biological feature). He now battles as Alice's Bakugan guardian (because the Silent Core's negative energy finally leaving him and Alice, leaving Alice as just herself, without Masquerade), caring for her as much as she cares for him.

Spectra's Guardian Bakugan. Helios is an evil dragon that obeys every command from the heinous Spectra. Its mammoth wings allow it to move swiftly and avoid quick attacks. Helios has poisonous tipped thorns covering its body. From its mouth, it can shoot cannonball fire blasts with rapid speed. The key point of the original Helios is that 1 he uses his abilities general quasar which is usually unused for the rest of the bakugan series. Another key point being that in this form with help from the forbidden cards he manages to defeat Drago. but for some reason Spectra doesn't use the forbidden cards ever again.

• Cyborg Helios

Helios suggested that he be turned into a cyborg, since it would not have any of the weaknesses of a completely mechanical Bakugan. A computer voice can be heard when he uses his new ability FARBAS to repair himself and increase his power to match his opponents. In this form, Helios can use more cybernetical attacks like Ragnorok Cannon which soon begins to evolve into the realistic gun-like weaponry in the Bakugan series.

• Helios MK2

The power of the forbidden cards forced him to evolve artificially. Even more of his body is mechanical.
