of the main UK championship, Razer won the concurrent Pinball Warrior Tournament side event and retained the Best Design award. Immediately after filming series three, Razer participated in the International Championship. Following forfeiture by Prometheus, its scheduled first opponent, Razer beat the Dutch representative Techno-Lease and Irish entrant Diotoir to win the tournament. Razer also fought in the direct-to-video First World Championship, representing England. Dominant victories over the Scottish robot All Torque and fellow English entrants Chaos 2 and 101 put Razer into the Final against compatriots Behemoth. In a very closely fought contest that was not without moments of controversy, Razer won the fight on a split judges decision, the tournament and its associated title. In the first round of its series four heat, Razer progressed alongside Robochicken from a three-way battle in which Velocirippa was eliminated. In its next battle against Milly-Ann Bug, Razer methodically removed all of its opponent's wheels, rendering Milly-Ann Bug unable to move. In a post-battle interview with host Craig Charles, Blood likened this attack to "pulling the legs off a spider". Early on in its heat final against Pussycat, Razer malfunctioned. Stuck in forward drive, it careered into the arena side wall with the rear wheels spinning but unable to steer. Pussycat severely damaged the back end and wheels of Razer, until Dead Metal of the house robots pitted the machine. Although Scott and Blood were gracious in defeat, Lewis turned his back on the fight, left the control booth immediately afterwards, and refused to be interviewed by Craig Charles. Lewis accused the Pussycat team of breaking a gentlemen's agreement that both teams would not seriously damage the other's machine. However, seeing that Razer's wheels were still spinning, Team Pussycat were unaware that Razer was in fact immobilised. Razer also took part in the Pinball Warrior and Sumo Basho side tournaments of series four; its performances were underwhelming in both events, scoring 95 points in the former having abandoned the run partway through to attack Sir Killalot, and lasting less than five seconds in the latter. Southern Annihilator – Series 5 Razer's next appearance came in a Robot Wars Christmas special called the Southern Annihilator. Six robots fought at the same time until one was eliminated, either through immobilisation or judges' decision. The remaining five robots then fought again, eliminating another, and so on until one robot remained and was declared the winner.
