Krakix is a samurai-like Bakugan. He is the Guardian Bakugan of Gill in Bakugan: Gundalian Invaders. His Battle Gear is Vicer. Until He, Gill, Airzel and Strikeflier were killed by Barodius and Phantom Dharak.
Krakix first appears briefly in Final Fury, embedded in the footage Professor Clay received from an unknown source.
In A New Beginning, Krakix makes a second appearance in the background of Dan's vision.
In The Secret Package, he makes his physical debut with Strikeflier and Lumagrowl, during their combined effort to destroy the Neathians' first security shield.
In The Element, after Rubanoid assumes his Bakugan form to attack Barodius in retaliation to his insults, Krakix ambushes him from behind, knocking Rubanoid unconscious.
In The Sacred Orb, he and the other Twelve Orders Bakugan attempt to take down the second shield. He and Gill end up facing Captain Elright and his Haos Raptorix, in a neck-to-neck fight until The Sacred Orb intervenes and returns the Gundalians to their home.
In Partners Til' The End, Krakix and Gill lead an effort in gaining data about the Neathians' remaining defenses. Following Contestir's failure to defend him from airborne attacks by Hawktor, Krakix is forced to abandon the shield and join in the battle. Krakix quickly manages to immobilize Hawktor with Vicer, only to be waylaid by Lumino Dragonoid, who frees his ally and turns the tables against Krakix and Contestir. After losing the battle, Krakix leads Contestir outside of Gill's ship and attacks him in an almost successful attempt to kill his fellow Gundalian.
In Colossus Dharak, he briefly battles Coredem, and their battle continues into the following episode.
In Dragonoid Colossus, Krakix's conflict with Coredem is resolved when he uses Vicer to finish him.
In Into the Storm, Krakix successfully scans the third shield only to discover its DNA encryption, which prevents any Gundalian from passing through.
In Infiltrated, he battles Hawktor and Akwimos with minor assistance from Airzel and Strikeflier. Krakix manages to defeat both opponents with a Level 2 Battle Gear ability after Strikeflier is blindsided.
In Final Strike, Krakix and Gill successfully locate the Brawlers again and attempt to kill them before they can send out any Bakugan. Linehalt intervenes and initiates a battle between the two, which the Gundalian turncoat later flees.
In Gundalian Showdown, Krakix joins Lythirus, Strikeflier, and Lumagrowl as they make one last effort in impeding the Brawlers' escape to Neathia. Despite being badly outnumbered, the four Gundalian Bakugan hold their own until Blitz Dragonoid defeats them one at a time, excluding Lumagrowl.
In Code Eve, he attempts to prevent Sabator, Aranaut and Avior from escaping Gundalia. Avior knocks him down, allowing for the others to elude Krakix's attacks and flee to Neathia. He and Gill follow and join the battle shortly thereafter, with both eventually falling victim to a deliberate fatal blow from Phantom Dharak.
And he is voiced by Keith David in the English and will be voiced by Nobuyuki Hiyama in the Japanese dub.
