|~ Hydranoid to his mechanical counterpart Hades|
Hydranoid is a villain-turned-hero from Bakugan. He later redeems himself to help Dan and Drago and decides to join the Brawlers and also helped Drago to defeat Naga.
Hydranoid was originally Masquerade's Guardian Bakugan, but now he is Alice Gehabich's Guardian Bakugan because Alice receives him from Masquerade who renounces his villainous ways, in a way, Hydranoid has three heads who had the same personality and the same voices, he is voiced by Izo Oikawa in the japanese version and by Craig Marshall in the english version and currently by Rob Tinkler.
Hydranoid started as an adversary to Dan and Drago by sending the fallen Bakugans to the Doom Dimension, but after he finds out that Hal-G has bigger plans than him, he becomes loyal and friendly towards Drago and his friends and manages to take down the Doom Beings and join the Battle Brawlers.
Despite being an adversary, Hydranoid is a nice guy who trusts Alice Gehabich after Masquerade leaves her body. Hydranoid is a dragon who is able to defeat the Doom Beings and Naga's minions who attempt to take over the Earth and Vestroia for no reason. Hydranoid manages to defend Drago from Naga who is not happy to see Hydranoid as an traitor. Helped by Drago, Hydranoid encourages him to kill Naga for treachery and other villainous deeds that this latter did earlier on Earth.
In the season 2, Hydranoid has a robotic look-alike named Hades who was created by Clay Fermin who has used his DNA to create a robot copy of him. Hydranoid helped by Fourtress and Chan Lee manage to destroy his robotic look-alike by showing his true powers by proving he is the real one, Hydranoid was later defeated by MAC Spider.
In the season 4, he tried to defend New Vestroia by trying to kill Mechtavius Destroyer, but was destroyed, but after the Battle Brawlers use the Current of Time, Hydranoid and the Bakugans are revived.
