Alpha Hydranoid (アルファードヒュドラ Arufādo Hyudora, Japanese version Alphard Hydra) is a Bakugan, the evolution of Dual Hydranoid and the final evolution of Hydranoid. He was originally the Guardian Bakugan of Masquerade, an alternate personality of Alice Gehabich, but he was given to Alice after Masquerade's personality was destroyed.



The three-headed Alpha Hydranoid is a dragon-like Bakugan, featuring a dark skin tone that makes him difficult to see at night. His hard, metallic armor can sustain multiple blows from attackers, and his dark blasts can destroy all elements.

Alpha hydranoid

Alpha Hydranoid is the second evolution of Hydranoid - coming after Dual Hydranoid. It evolved after Masquerade's brawl with Exedra. In Behind the Mask of Masquerade, he battled against Drago and lost.

When Masquerade left Alice's body, Alpha Hydranoid became Alice's Guardian Bakugan. With Alice, he has been far less destructive and aggressive towards his opponents, especially Drago, whom was once his greatest foe. This is the only Bakugan that has had two former masters without being taken by force.

When Alpha Hydranoid fought alongside Alice against Rabeeder, Rabeeder crystallized him and almost transformed him into a statue, yet since his heads were still free, Alice realized that Hydranoid could still perform his signature move—Death Trident—to take down Rabeeder. Alpha Hydranoid's three heads each have their own distinctive voice, however they all share the personality. He has shown unconditional affection for Alice, spending much of his time on Earth to accompany his master.

Bakugan: New Vestroia

In a way, Alpha Hydranoid gave birth to the Battle Brawlers Resistance as Mira heard him talk when he was being tortured by Professor Clay and his assistants, making her realize the Bakugan were intelligent (sentient level) creatures and formed the Resistance to set them free. A mechanical mimic of Alpha Hydranoid named Hades was used by Shadow Prove in his battles against Shun Kazami, Dan Kuso, and Baron Leltoy and later in a rematch against both Shun and Marucho Marukura (Shadow had brawled Marucho in his battle prior to his first use of Hades against Shun). The mimic was created by Professor Clay possibly from the data the Vexos got from torturing him. In the episode preview Shun calls him Hydra. He is friends with Ingram.

Alpha Hydranoid is then freed by Mira, Shun, and Marucho as well as the other Bakugan that Prince Hydron had turned to bronze statues. When Dan, Marucho, Shun, and the other brawlers' Guardian Bakugan return to earth, Alpha Hydranoid returns to Alice. Based on Drago's statement about the Six Fighting Bakugan who were captured Alpha Hydranoid was the fourth with Preyas, Hammer Gorem, and Storm Skyress being the first three respectively and Blade Tigrerra being the last.

Alice and Chan Lee team up against Shadow Prove in Shadow Attack. Hydranoid destroyed Hades but was beaten by MAC Spider.

Sometime between the repair of Bakugan Interspace and Mechtavius Destroyer's revival, Hydranoid returned to New Vestroia.

Bakugan: Mechtanium Surge

In Blast from the Past, he was seen with an army of Bakugan trying to protect New Vestroia. He was later destroyed by Mechtavius Destroyer.

Because the Brawlers used the Current of Time to go back and destroy Mechtavius Destroyer before he killed him, he is now either living peacefully on New Vestroia or reunited with Alice at some point.

A non-metal translucent version was released as part of the Masquerade Brawler's Evolution starter set, which also included Hydranoid and Dual Hydranoid.

Alpha Hydranoid was re-released for Mechtanium Surge, along with Dharak and Cyborg Helios, as part of the BakuEvolutions "Evil" set. Available in Darkus only, it received a new color scheme to match the other Mechtanium Surge Bakugan and a DNA Code for online play. This is currently the strongest version available at 800 Gs.

Alpha Hydranoid isn't available in the Bakugan Battle Brawlers Video Game, though he is available in Bakugan Battle Brawlers: Battle Trainer.

  • In New Vestroia, Alpha Hydranoid's power level actually decreased to 500 Gs. His G-Power was originally 550.
  • Including the fact that Alpha Hydranoid is used by a Russian character, it's possible that he is based on Zmey Gorynych, a three-headed dragon from the Russian Folklore.
  • He may be a reference to the Godzilla kaiju King Ghidorah as both are three-headed dragons, both is/were villains at one point, both were used in world-threatening events, (King Ghidorah's masters were going to invade the world and remake it in their own image similar to Masquerade) and both's owners were main antagonists during the time, (with Alpha Hydranoid's being Masquerade and King Ghidorah's being the Xilliens).
  • Alpha Hydranoid is based on the Hydra, a monster in Greek mythology that had nine heads, and had two heads to replace every single head that was destroyed.
  • In the original series, when Masquerade threw Alpha Hydranoid into battle, he would perform a series of spins and swerves before standing. This also occurred when Hades, disguised as Alpha Hydranoid, was sent into battle. After he started being used by Alice, he ceased doing these stunts.
  • Hydranoid and Dual Hydranoid were the only Bakugan owned by a major antagonist to evolve by battle experience.
  • On Bakugan Dimensions, he has a very substantial amount of strength and agility for a Darkus Bakugan.
  • He appears to be very physically strong, as he is able to fly while carrying Preyas, Blade Tigrerra, and Hammer Gorem with ease.
  • He is also one of the three Bakugan evolutions that Leonidas could've battled, but has not battled the video game, the other two being Silent Naga and Ultimate Dragonoid.
