C-105, a variant of A-105, is an multimonster entity (multimonster entities having multiple faces rather than one) that resides within the ? Section of the Rooms. It used to reside within the A Section, and sightings of it have been rare as of late. It is cyan, and announces itself by tinting people’s vision cyan rather than A-105 being green (and tinting others’ vision green). It acts very similarly, checking grey lockers.
