Factory Workers were worker robots in the Mechanoid Factory on Kalidon. Their job was to help build the Mechanoids that the factory churned out. They were yellow with a single red eye, and had the ability to shrink to microscopic size when threatened.
- Although they did not attack Ratchet directly, if he got to close the Factory Worker, it would shrink down and attack Ratchet while in a microscopic size. While this was proven to be a bug, it counts has the Factory Worker's only attack.
