You are a pale imitation, who is about to feel the wrath of a true hydra!
Alpha Hydranoid talking to Hades, Shadow Attack

Alpha Hydranoid (Japanese version: Alphard Hydra (アルファードヒュドラ, Arufādo Hyudora?)) 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 faded away.


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.

Bakugan New Vestroia Handbook

  • Appearance: A three-headed winged dragon with metal armor plates protecting his body.
  • Battle Style: Alpha Hydranoid's fire blasts melt even the strongest elements.
  • Where You've Seen Him: Alpha Hydranoid is the third step in the evolution of Hydranoid, a one-headed Dragonoid-like Bakugan. Alpha Hydranoid evolved when he battles with Dan and Drago to help save Vestroia from destruction. Later, he became the Guardian Bakugan of Masquerade.

Bakugan Ultimate Handbook

This evolved form of Hydranoid comes equipped with metal armor that can take blow after blow. He can launch fireballs from each of his mouths that are capable of melting just about anything. Alpha Hydranoid prefers fighting at night so he can blend into the darkness and catch enemies by surprise.


Bakugan Battle Brawlers

Alpha Hydranoid is the second evolution of Hydranoid, coming after Dual Hydranoid. It evolved after Masquerade's brawl with Exedra.

He battled against Ultimate Dragonoid and while he did tie with him for most of the battle lost in the final round.[1] Later Masquerade used Hydranoid for the last time to help Ultimate Dragonoid beat Nagas Gate keepers Centorrior and Druman. While Hydranoid fell in Lava he was reveled to have wings and used his Darkus long range attack for finish off Centorrior while Drago beat Druman.

When Masquerade left Alice's body, Alpha Hydranoid officially became Alice's Guardian Bakugan. With Alice, he has been far less destructive and aggressive towards his opponents, especially Drago, who 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 Juggernoid and Sirenoid. 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 same personality. He has shown unconditional affection for Alice, spending much of his time on Earth to accompany his partner.

He then joins the heroes to beat his former boss Naga once and for all. He gives Drago his strength which he uses to kill Naga and get rid of Hal-G. When the battle was over, Hydranoid says goodbye to Alice and returned to New Vestroia.

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.

Hydranoid and Fourtress team up against Shadow Prove. Hydranoid managed to destroyed Hades but, due to being exhausted from the battle, was beaten easily by MAC Spider.[2]

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

Bakugan: Mechtanium Surge

He was seen with an army of Bakugan trying to protect New Vestroia. He was later destroyed by Mechtavius Destroyer.[3]

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 has reunited with Alice.

Evidence of other possible Attributes for Alpha Hydranoid

Alpha Hydranoid was available in Bakugan Dimensions. It was only available in Darkus, although other attributed DNA Fragments were seen.


  • 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 dragon-like aliens, 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 of their 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.
    • Its Japanese name is a reference to Alphard, the brightest star in the constellation, Hydra.
    • When using one of his ability cards, Destroy Vanish, his main three heads with the addition of his six miniature heads from the ability adds up to 9 heads in total, just like the monster Hydra.
  • 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 did not battled in the video game, the other two being Silent Naga and Ultimate Dragonoid.
  • His ball form in the game is different from the anime ball form. The arms in the game's ball form are actually his second and third heads in the anime.
  • Since he evolved, Alpha Hydranoid has not won a 1-on-1 battle. He has won group battles against Naga's underlings and beat Hades and the Bakugan Trap Fortress when helped by Pyrus Fortress, but lost against both Drago and MAC Spider .
  • The Hydranoid evolutionary line from Pokémon Black & White might have inspired Deino --> Zweilous --> Hydreigon. Both represent dark and dragon qualities, both gain heads through evolutionary line, both seen to be strong through their first generations seen, both decrease in power with future generations to come.
