Akwimos (Japanese version Hopper (ホッパー, Hoppā?)) 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. His Battle Gear is Gigarth.
Akwimos partners with Marucho of the Bakugan Battle Brawlers. He has powers that can't be beaten when it comes to underwater battles. Akwimos can create devastating attacks using water energy balls. With his claws tucked under both hands, he can break and nullify the powers of the Gate Card. Friends think he's very comical and funny.
His digital clone fought 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.
Marucho programmed the digital Akwimos to speak, and 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 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.
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.
He battled Coredem, who had used Rock Hammer. He also used Gigarth and ended the battle in a draw.
He continued his battle with Strikeflier but retreated with Marucho due to seeing Dan and Jake.
He battled against Lumagrowl, Lythirus, Krakix, and Strikeflier alongside Blitz Dragonoid, Dragonoid Colossus, Hawktor, Aranaut, Linehalt, and Coredem.
