Dual Hydranoid to Drago, Show Down

Dual Hydranoid (Japanese Version: Dual Hydra (デュアルヒュドラ, De~yuaru Hyudora?)) is the evolution of Hydranoid and Masquerade's evolved Guardian Bakugan, and later Alice Gehabich's when he evolved as Alpha Hydranoid in Bakugan Battle Brawlers.


Dual Hydranoid now has two heads. The start of a saw on Hydranoid's chest has now become a fully developed metal saw that is now movable. In addition to his two heads, Dual Hydranoid also has two tails. The number of spines Hydranoid has increases and become sharper and longer. With this new evolution, he is now bipedal (stands on two legs). He can now grow a new head if one has been cut off.[1]

Bakugan New Vestroia Handbook

  • Appearance: A two-headed dragon with sharp spikes on his back and wicked claws. Dual Hydranoid has two tails. The blades of a circular saw protrude form his chest.
  • Battle Style: Fierce. Every time Dual Hydranoid defeats an opponent, he gains energy.
  • Where You've Seen Him: Masquerade used Hydranoid to take on the Battle Brawlers of Earth. After he defeated his minions, Chan, Julio, Klaus, Komba, and Billy, Hydranoid gained enough power to evolve into Dual Hydranoid.[2]

Bakugan Ultimate Handbook

This Bakugan is extremely strong, and it steals energy from Bakugan sent to the Doom Dimension to become stronger. Only a cruel and heartless creature could do that! In battle, Hydranoid is hard to defeat, thanks to its tough outer skin and double heads. It lashes out at opponents with its long tail. Hydranoid may not be able to move fast, but it makes up for its lack of speed with the sheer force of its attacks.[3]

Dual Hydranoid's Bakugan form

Masquerade's Darkus Hydranoid evolved when Masquerade battled his comrade's Bakugan. It's evolution was caused by the power from the Bakugan that were sent to the Doom Dimension. It evolved during the battle with Klaus and Sirenoid. He starts off using Gazer Exedra on Klaus's Griffon sending it to the Doom Dimension. In round 3, he battles Sirenoid but the battle stops due to Klaus using peacemaker ending the round in a draw. In round 5 he comes back and gets trapped by Klaus's Mine Ghost card. He uses grand down which nullifies Klaus's gate card. Hydranoid uses his energy blast to sent Sirenoid to the Doom Dimension thus winning the battle. [4]

He appeared during Dan Kuso and Masquerade's third battle and battled Delta Dragonoid telling him two heads are better than one. Dan opens his gate card and the two Dragons battled in a head to head clash. Hydranoid uses his tails to attack causing Drago to punch him in the head. Hydranoid bites Drago's face causing him to punch Hydra again. He then used duel Gazer to send Saurus to the Doom Dimension. Drago then uses wall burst causing his own attack to hit one of his heads. Hydra head comes back due to Masquerade throwing a card in the air ending the round in a draw. In round 5 him and Drago battle again. Dan opens his character card giving Drago more power. He then uses gazer extra giving him more power. Drago then uses D-Strike Attack giving him more power for the rest of the battle. He uses Destruction Impact which Nullifies dan's gate card and causes Drago's fire attack to be useless. He then finishes Drago off with a tone of energy blasts causing Drago to be sent to the Doom Dimension and winning him the battle. [5]

He is later shown in Masquerade's hideout telling his master he feels more stronger than ever and wants to battle. Masquerade says he will grant hydra his wish as they challenge Shun Kazami to battle. He then battled Skyress, Tigrerra Gorem and Preyas beating them off-screen, though all of them lost on purpose in order to save Dan and Drago.[6]

In You're Going Down Clown Hydranoid appeared in a flashback during Drago's battle with Apollonir when Dan notes how being trapped in the Doom Dimension has made them battle to help Drago evolve.

He battled Wavern and lost.[7]

Dual Hydranoid evolved into Alpha Hydranoid at the end after defeating Exedra with Darkus Gazer Dual.[8]

  • It is one of the first Special Attack Bakugan originally packaged in Booster Packs.
  • On the Bakugan official website, Dual Hydranoid's provided picture is wrong, because it says Hydranoid (Dual-Headed) with an Aquos Toy Dual Hydranoid and a Normal Darkus Hydranoid.
  • Dual Hydranoid is based on the Lernean Hydra, a monster in Greek Mythology, that started with a single head. Its head would regrow and multiply if decapitated.
    • Even so, Dual Hydranoid's ability to regrow its heads is not entirely an accurate reference. The original Lernean Hydra would, upon decapitation, regrow two in place of the original, allowing it to further "evolve" into a more deadly creature. Dual Hydranoid did not ever demonstrate this, so it can be assumed that the only way for any Hydranoid to gain any additional heads is through evolution.
  • In the Bakugan Official Handbook, Dual Hydranoid and Hydranoid's descriptions are merged into one, with an image of the toy form of Dual Hydranoid, due to a toy form of unevolved Hydranoid not existing at that point in time.
  • He may also possess the Ultimate Warrior Gene as in Show Down, he managed to defeat Drago (or send him to the Doom Dimension).
