{{Nihongo|'''Hydorous'''|ハイドロス|Haidorosu}} is a lion-like [[Bakugan]] that appears from the reboot series, debuting in ''[[Bakugan Battle Planet]]''. He is the current [[Partner Bakugan]] of [[Shun Kazami (Reboot)|Shun Kazami]], with the exception of being replaced by [[Sharktar]] in ''[[Bakugan: Geogan Rising|Geogan Rising]]'' until the latter became the guardian of both the Aquos Crystal and Aquos Artifact before Hydorous awakened from hibernation and returned to Shun in ''[[Bakugan: Evolutions|Evolutions]]''.

[[Hydorous (Shun Kazami)|An Aquos variant]] appears in the anime as [[Shun Kazami (Generation 2)|Shun Kazami's]] [[Partner Bakugan]] for most of the series, with the exception of ''[[Geogan Rising]]'', where he is temporarily replaced by [[Sharktar]]. A [[Darkus#Reboot|Darkus]] variant 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.<refname="bakulog">[https://web.archive.org/web/20220127211045/https://bakugan.com/en/bakulogBakugan.com Bakulog]</ref>
