The Bits first appeared to greet Professor Von Schlemmer after he returned from the science center with Silver the Hedgehog, and then demonstrated to Silver how the Bigger-Maker Machine worked after he became curious of the professor's inventions. Later, when Onyx City Council tried to despose of Silver and Von Schlemmer by launching them into a Genesis Portal, Von Schlemmer revealed he had the Bits with him and activated them to help the pair escape from the portal. However, a powerful creature called the Second Devourer follow them and began to terrorize Onyx City. Gold the Tenrec used her telepathy to link her mind, Silver's mind and the minds of the Bits to Von Schlemmer so he can quickly modify his Bigger-Maker Machine to enlarge Silver big enough to combat the Second Devourer.
