Razer outlasted Vercingetorix, Spawn of Scutter, Behemoth and Attila the Drum to set up a final against Onslaught. An attack by Razer's arm on one of Onslaught's rear wheels saw its adversary shed a tyre, lose grip, and drive into an area patrolled by Matilda. The house robot flipped Onslaught onto its side, rendering it immobile. Assured of victory, Razer proceeded to attack Matilda, causing horrific damage to Matilda's bodywork and rear shell, and then pushed her over a flame pit to set her on fire. It next took part in the All-Stars tournament of Robot Wars Extreme, beating Gemini, Behemoth and Firestorm 3 to establish a grand final against Tornado. In their first competitive encounter, Razer repeatedly pierced Tornado's low, flat body, eventually breaking their drive chain. Tornado was immobilised, and Razer won a second consecutive trophy. Its only other battle in Extreme was a grudge match with Pussycat, in response to the accusation that the Pussycat team had broken an agreement with the Razer team during their series four heat. Razer punctured Pussycat's body and lifted it with the arm but Pussycat fell and escaped. In doing so, Pussycat impacted the steel guard around Razer's front right wheel and jammed the metal into the wheel itself, rendering Razer completely unable to move and it was subsequently counted out. Ian Lewis of Team Razer competed in a seven-way melee featuring antweight robots—miniature machines that weighed less than and fitted into a four-inch () cube. Lewis's robot for this battle was Razzler, a modified Razer toy. Razer's next tournament was the Second World Championship. Its title defence began with qualification from a melee against Diotoir, Flensburger Power and The Revolutionist. It then beat fellow English representative Tornado in the semi-final before facing walking robot DrillZilla in the final. Being classed as a walking robot, DrillZilla could ignore the normal weight limit and thus had thick armour; knowing that they would be unable to pierce this, Razer concentrated on inflicting cosmetic damage to its opponent's rubber feet. This proved enough to secure victory on a judges' decision, enabling Razer to retain its World Champion title. On a 12-battle victory streak, Razer fought in the eleventh heat of the fifth series of Robot Wars. Therein, it defeated Big Nipper, Widow's Revenge—a machine reportedly constructed by the Razer team's wives—and Rick to reach its first series semi-final. Their next opponent was Spawn Again,
