War Machine's first bout was against One Tin Soldier. Both robots drove out and One Tin Soldier hit War Machine with its spikes, doing no damage. War Machine then utterly dominated One Tin Soldier, slamming it into the wall, pushing it into the killsaws and the pulverizer, and just driving One Tin Soldier around. Eventually, One Tin Soldier lost drive power in one wheel, and then time ran out. War Machine won an unanimous 45-0 judge's decision to advance to the second round against Snake.
In this battle, War Machine waited until Snake inched toward the center, then rammed Snake in its midsection against the wall. It kept ramming Snake as Snake tried to attack, and smoke started coming out of Snake. Eventually, Snake gave up and attempted to attack the pulverizer as it was counted out.
War Machine then advanced to the quarterfinals against DooAll War Machine was the clear dominator in this match, slamming DooAll around the arena. Both robots did some pushing, however, and the match lasted the whole three minutes where a 38-7 judge's decision advanced War Machine to the semifinals against Diesector.
In this battle, after both robots attempted to get under each other and took a shot from the killsaws, Diesector wedged underneath War Machine and lifted it onto its back against the wall. Unable to move, War Machine was counted out.
War Machine wasn't finished, however, as it was one of nine robots to enter the superheavyweight royal rumble and it performed well. It was one of only two competitors still alive at the end, but lost the judges' decision to Toro.
