Hydorous (ハイドロス, Haidorosu?) is a lion-like Bakugan that appears in Bakugan Battle Planet. He is the Guardian Bakugan of Shun Kazami. Hydorous is a noble and fierce Bakugan compared to his partner, who is timid and shy in front of cameras. A Darkus Hydorous also appears in Outer Demons, controlled by Shun's Doppelganger.
Fast, agile and ruthless in battle, the overtly-aggressive Hydorous is the prince of the seas. Though his style is a complete 180 from Shun's thoughtful manner, the two compliment one another in battle and life.

Shun Kazami presumably met Hydorous at an unknown time before Shun left Japan to join The Awesome Ones. Hydorous is seen with Shun as he discovers the Awesome Ones' videos.
He first appears during a battle between a mysterious individual and Aay. Later that day, his partner Shun asks the AO if he could become the next member of their time. Magnus also wants to join; this causes Dan to start a competition to see which brawler will be added to the team.
In one event of the competition, the Brawler and their partner must race to the top of a mountain, Shun rides on Hydorous but is attacked by Magnus' Webam during the race. Hydorous battles against Webam but is also attacked by Magnus' Fangzor. Lia and Wynton send out their Bakugan to assist Hydorous but the two lose the fight, Webam then takes Hydorous down as Magnus proclaims his power that "proves he should be member of the Awesome Ones". Despite losing the battle, Hydorous and Shun become members of the Awesome Ones due to them caring for each other and being good teammates, Magnus did not get the chance because he focused on himself and his power rather than his partner Bakugan.
Hydorous is among the rescue party that rescues Bear from Strata the Hunter.
