Noisy Boy was a fighting robot from Japan. In the past, it had apparently fought for the WRB belt and got very close to winning it before losing to Unicron. Years later, it is sent to America after being brought by Charlie Kenton. He took Noisy Boy to an underground bot boxing match. He was matched up against Midas. Noisy Boy fought valiantly against Midas, but Charlie who was controlling Noisy Boy messed up the controls causing Noisy Boy to take heavy beatings from Midas. Eventually, Midas smashes off Noisy Boy's head causing it to hurtle off into the distance.
