Brawl was created 149,450 years ago in order to drive the Vrai out of the Matoran Universe as part of a group called the Elite Makuta, which also included Blackout, Barricade, Starscream and Bonecrusher. After this was accomplished, Barricade, Brawl and Bonecrusher were placed in stasis pods.
When Blackout created Darkmount and flew into space, he took the pods with him, and later ordered Malygos to retrieve a crystal, hidden by the Great Beings on a distant planet, which would reawaken the Makuta. Then, Ynot, the Makuta Anima and The Fallen attacked, beginning the Battle of Darkmount. Brawl fought Sasuken and Asumaru, and managed to melt some of the former's armour.
Later, he fought Ynot and Kakamu alongside Blackout.
Much later, during a fight, he snuck up on and impaled a clone of Tahar'ok.
When Blackout travelled to the Shattered Mirror Universe, Brawl was in charge of shooting at the SMU Mata Nui robot's Core Processor.
After Blackout broke into the Real World, invaded BZPower, he went on a rampage capturing random people, including Treveya. Klak tried to free her, but came face-to-face with a troop of Exo-Toa led by Brawl. Brawl captured Klak and stuck him in a prototype prison chamber.
During another space battle with the Wigwam, Le Chiffre ordered Brawl to "BLOW UP STUFF!!!!!". He then started mashing buttons on one of Darkmount's consoles, causing it to fire lots of nasty things into a hole in the Wigwam's shields.
Brawl then accompanied Le Chiffre and his Rahkshi to the surface of a planet. There, Le Chiffre had his Rahkshi to take out Brawl as part of his bid for the Chamber of Secrets. However, he survived.
