Eraser was unable to do anything to Little Drummer Boy as it took hit after hit from its drum. Eventually the robot stopped moving altogether and was knocked out at 1:36. The lifting spike mechanism was irreparable due to the damage caused by Little Drummer Boy. This loss meant that Eraser was eliminated from the tournament.

Eraser was repaired in time for the middleweight royal rumble, where it was eventually hung up on the spikestrip after fighting aggressively. In the end, T-Minus was declared the winner of the middleweight royal rumble and Eraser lost overall.

Eraser started hitting Psychotron with its spinning drum again, which it managed to raised Psychotron's lifting arm for a brief moment, and Psychotron pushed Eraser toward the screws. At the end of the fight, Eraser threw a drive chain, which immobilized half of its drive. Even with this handicap, Eraser was very aggressive but Psychotron won on a 27-18 judge's decision.

Eraser was repaired in time for the middleweight consolation rumble, fighting aggressively but eventually getting a drive chain severed by Sunshine Lollibot.
