|Portrayed By:||Kevin Bernhardt|
Pistonhead is the name of the cenobite who was created from J. P. Monroe.
Monroe purchased the Pillar of Souls to be the centerpiece of the artwork that adorned his private room in his nightclub The Boiler Room. From that pillar came Pinhead who then converted Monroe into a cenobite.
Pistonhead is aptly named for the piston that constantly pumps in his head.
