During events in Portal, he worked behind the scenes to scribble messages and warnings to Chell on the walls, leading her out of the testing chambers and towards GLaDOS. The Lab Rat comic reveals that, despite his madness, Ratman identified Chell as a rejected test subject due to her high tenacity, and moved her to the top of the queue for testing. Already sceptical of the computer, the man fled from the gas and kept himself hidden from GLaDOS' view, slowly becoming more insane over an unknown stretch of time. In Prior to GLaDOS' rampancy and the neurotoxin release, Ratman was Aperture scientist Doug Rattmann.

Ratman’s full appearance is only seen in the Portal 2: Lab Rat webcomic released by Valve prior to Portal 2 's release to tie the story of the two games together. In the two games there are various hidden rooms, so-called "Ratman dens", where Ratman has left scribblings and paintings on the walls. He was a former scientist working at Aperture and one of the few who survived when GLaDOS flooded the facility with neurotoxin. The Ratman is a character in both Portal and Portal 2.
