Changes

Macubass debuted in ''[[Saved By the Siren]]'', where Mylene used it in an ill-fated attempt to acquire [[Knight Percival]]'s Darkus Attribute Energy. After Macubass lost in a brief first round, Mylene used its '''ABSIDS''' ability and won the second round. Quickly employing exactly the same strategy, Macubass nearly won the brawl, only to be interrupted by the appearance of [[Klaus von Hertzon|Klaus]] and [[Sirenoid]], who backed up Percival. Though holding its own for a while longer, Macubass was trounced by a powerful attack from Percival.

In ''[[Earth Invaders]]'', Macubass was used a second time, this time whilst tagging with [[Aluze]] against [[Magma Wilda]] and [[Blade Tigrerra]]. Despite minimal back-up from Aluze, Macubass battled alone for the majority of the brawl and more than held its own before setting up its opponents to a precision strike from an airborne Aluze. After Aluze was quickly eliminated in the second round, Macubass took command of the brawl by overwhelming its opponents with a plethora of attacks that nearly drowned the both of them. After Tigrerra was eliminated while in attempting to save Wilda, Macubass unleashed its '''ABSIDS''' again to take his Subterra Attribute Energy.

In ''[[Ambush]]'', Macubass tagged tags with [[Boriates]] while aiming to take the Ventus Attribute Energy in a battle with [[Master Ingram]] and [[Saint Nemus]]. Due to the usage of the Vexos Trap Field, which continuously restores the G-Power of all Mechanical Bakugan, the brawl is brief and both opponents are defeated, resulting in the Vexos's acquisition of the Ventus Attribute Energy.

In ''[[Mylene's Meltdown]]'', Spectra and Mira trapped trap Mylene and Shadow inside [[Bakugan Interspace]] and initiated initiate a brawl, resulting in a second bout between Macubass and Magma Wilda. Despite a distinct environmental advantage from the '''Aquos Reactor''' Gate Card, Macubass and Wilda are evenly matched before Wilda uses his most powerful abilities to utterly burn and crush Macubass, leaving only its legs intact from a finishing blow.
