In Hydranoid's unevolved form he walks on four legs, has three purple teeth jutting out from his upper jaw, and a long neck and tail. It also has pink spines running from the middle of its neck to about the end of its tail, which somewhat resembles the tail of a stegosaurus. In addition to this, he has a large pink horn on its nose and red eyes. It also has the starting of the blade in the center of its chest although it cannot move yet. As he evolves, he gains one more head.
Its entire body is composed of a highly intelligent, independent cell structure. His tail can be a very dangerous weapon along with his bite and power blasts.
Masquerade has complete power over Hydranoid; its ultimate evil master. As his partner, it is cruel and merciless in battle, and feeds off of the energy gained from defeating an opponent. Masquerade uses Hydranoid to become the ultimate Bakugan so that Hydranoid can hold and bring the Infinity Core to Naga. It is later revealed that Masquerade wants to become the greatest Bakugan Brawler in a battle with Alice and Exedra in the Doom Dimension. Based on the words he uses, his motive for fighting for Naga, is for the glory of being great in battle.
As Alpha Hydranoid, he briefly teams up with Drago to help him and Dan defeat Druman and Centorrior, the two Pyrus/Darkus hybrid gatekeepers. Shortly afterwards, it becomes Alice's Guardian Bakugan, due to Masquerade fading away (along with the negative energy that corrupted them), and its demeanor becomes much less aggressive. He played an important role in the Brawler's quest to defeat Naga and unite Vestroia.
