The Badge-O-Matic is a toy produced by Acme Novelty Company, used to make fake, but convincing, badges. Although its intended use is as a toy for children, Miranda uses it to make fake IDs to facilitate her investigative reporting. One of these badges is given to Ben, which he then gives to Emmet in order to pass through the police roadblock at the Rest Stop following the murder of Malcolm Corley.
The Badge-O-Matic is only mentioned within the guide, in an advertisement from True Reporter Comics.
