The robot which lasted the least time on a raised podium with Shunt would be eliminated. Roadblock outmanoeuvred Shunt and pushed it off the podium, but not without driving off itself. Although Roadblock itself had fallen to the floor, it qualified for a one-on-one heat semi-final against fur-covered robot Nemesis. Therein, Roadblock used its circular saw to shred the fur before pushing Nemesis to the side of the arena. Nemesis' speed controller failed, and the battle ended with the house robots attacking Nemesis — including Sergeant Bash setting its fur on fire. In the heat final, Roadblock faced the axe-wielding robot Killertron, which landed an early attack on Roadblock's armour. However, in a subsequent charge it drove up Roadblock's wedge and was grounded. Roadblock took advantage and flipped its opponent upside-down, rendering them immobile. Victory in its heat meant Roadblock qualified for the series grand final. This six-way battle immediately followed the final heat of the series, and pitted the winners of each respective heat—Roadblock, Recyclopse, Robot the Bruce, Cunning Plan, Bodyhammer and TRACIE—against one another. TRACIE and Cunning Plan were immobilised simultaneously as TRACIE drove up Cunning Plan's wedge and became beached due to its low ground clearance. Recyclopse was next to be eliminated with a broken drive chain, before Robot the Bruce mounted and drove too far up Roadblock's wedge and was tipped onto its side. Roadblock and Bodyhammer were still mobile when time ran out, and the judges declared Roadblock the series winner. Returning as reigning champion, Roadblock took part in the seventh heat of "Robot Wars" series 2. Its armour for this series was upgraded from steel to aluminium, reducing its overall weight to 80.9 kilograms. In the Gauntlet, Roadblock was the first ever contestant robot to tackle the Sentinel obstacle: a swinging robotic arm formed from a modified backhoe digger. Although briefly pinned against the arena wall, Roadblock was able to pass the Sentinel and reach the end zone to qualify for the Trial. This second phase of the heat saw Roadblock knock down 34 barrels in a robotic version of skittles - just sufficient to reach the one-on-one battles. Herein, it pushed an immobile Killerhurtz into the midst of the house robots before victory in the heat final over Onslaught, which failed to move.
