Akwimos (ホッパー Hoppā, Japanese version Hopper) is a merman-like Bakugan. He was formerly Marucho's Guardian Bakugan (after Preyas, Angelo/Diablo and Elfin) in Bakugan: Gundalian Invaders and is succeeded by Infinity Trister.
Akwimos can create attacks using water energy balls. When his claws are tucked under both of his hands, he can nullify the powers of the Gate Card. He has little water jets on his waist. His friends may say he is very comical and funny, but if it comes to an underwater battle no one can beat him. His Battle Gear is Gigarth.
His digital clone appeared in True Colours to fight Linehalt and won after a long battle using Gigarth. After it beat Ren, Ren shows the brawlers what his Gundalian body looked like and established that they were not friends anymore.
In Hostile Takeover, Marucho programmed the digital Akwimos to speak. He programmed it with a laid back personality. The computer came up with the random phrase "Cool is the Rule, Dude" and he followed Drago around repeatedly saying that phrase, making Drago annoyed and the Brawlers puzzled. Later Fabia gave the brawlers the original bakugan that the digital clones were based on. Akwimos got along quickly with Marucho. He found the digital Akwimos's phrase nice, and it has since become his catchphrase. He fought Rubanoid and Buz Hornix alongside the real Coredem and won by using Gigarth.
He appeared again in Decoy Unit along with Coredem and battled Strikeflier and Avior. After failing to beat Strikeflier, Marucho had Akwimos use "Elemental Blue" to create a wall of ice so he could freeze the opponents in their place so Marucho and Jake could get the chance to leave.
In The Secret of the Orb, Akwimos battled with Aranaut against both Linehalt and Sabator. However, before they finished their battle, the Sacred Orb sent out a dimensional twister and ended the battle.
In Infiltrated, Akwimos attacked Gundalia Castle alongside Dragonoid Colossus, Hawktor; and Blitz Dragonoid. After they entered the castle, Akwimos, Marucho, Hawktor and Shun were separated from Dan and Drago, who had been trapped somewhere in the castle. They escaped and battled Strikeflier and Krakix. They knocked out Strikeflier but were unable to defeat Krakix.
In Jake's Last Stand, he battled Coredem, who had used Rock Hammer. He also used Gigarth and ended the battle in a draw.
In Dream Escape, he continued his battle with Strikeflier, but retreated with Marucho due to seeing Dan and Jake.
In Gundalian Showdown, he battled Lumagrowl, Lythirus, Krakix and Strikeflier alongside Blitz Dragonoid, Dragonoid Colossus, Hawktor, Aranaut, Linehalt and Coredem.
