His origin is unknown. People started to talk about him when he stole Plan X from the Pentagon Building. Many police tried to capture him, but Paper Doll Man shot them all with the Solar Ray Gun. Before anyone else can capture him, he usually disguises as an envelope or escapes by slipping through the crack of a door. It is strange how he is still on the loose, despite being made entirely out of paper. He also stole one of Heinz Doofenshmirtz's blueprints of his inators, such as the Ballgown-inator, Combine-inator, Dull-and-Boring-inator, Look-Away-inator, Amnesia-inator, Babe-inator, Stinkelkrampen-inator, Teleport-inator, Unretrograde-inator, and the Repulse-inator.
