Roidmude 061 was sent alongside Roidmude 014 and Roidmude 020 to accompany Mashin Chaser in a mission to take out Ultimate Lupin, who had gained the use of the Heavy Acceleration power possessed by the Roidmudes. 061 and the other two Low-Class Roidmudes attempted to attack Lupin, but were caught in the Lupin Gunner and had their data shattered and absorbed by the phantom thief.
Later on, 061 and the others had their data recreated as blank Lost Number Roidmudes and sent to fight Drive during Lupin's second match with the Rider. While 020 held Kiriko captive, 061 and 014 attacked Drive. However, Chaser suddenly showed up and held off and destroyed the two Lost Numbers while Drive rescued Kiriko.
