Pinhead is a fictional character from the Hellraiser series, first appearing as an unnamed figure in the Clive Barker novella The Hellbound Heart. The name "Pinhead" is derived from a sobriquet given to him by the crew of the first Hellraiser film; he is first credited as such in Hellbound: Hellraiser II. Nearly thirty years after The Hellbound Heart was published, the character was given the designations the Hell Priest and the Cold Man in the sequels that followed, The Scarlet Gospels and Hellraiser: The Toll. Pinhead is one of the leaders of the Cenobites, formerly humans but transformed into creatures which reside in an extradimensional realm, who travel to Earth through a puzzle box called the Lament Configuration in order to harvest human souls.

According to Clive Barker, as the writing of the Hellraiser script took place during the height of the A Nightmare on Elm Street, Friday the 13th and Halloween film series, his intended portrayal of Pinhead as an articulate and intelligent character was initially not well received by the producers: some suggested that Pinhead should act more like Freddy Krueger and crack jokes, while others suggested that he be a silent character like Jason Voorhees and Michael Myers. Barker insisted that Pinhead's personality be more evocative of Christopher Lee's portrayal of Count Dracula: "Part of the chill of Dracula surely lies in the fact that he is very clearly and articulately aware of what he is doing - you feel that this is a penetrating intelligence - and I don't find dumb things terribly scary - I find intelligence scary, particularly twisted intelligence; it's one of the reasons why Hannibal Lecter is scary, isn't it? It's because you always feel that he's going to be three jumps ahead of you."  Though described by Pinhead's human half in Hellraiser III: Hell on Earth as being "very persuasive and very inventive", Pinhead prefers using coercive methods in order to obtain his goals, a fact which brings him into conflict with his ally, the demon Princess Angelique.  Pinhead can be reasoned and bargained with. In both Hellraiser and Hellraiser: Hellseeker, Kirsty Cotton bargains with Pinhead to offer him more "souls" in exchange for her own (in particular, her human adversaries), thus resulting in her life being spared. In Hellraiser: Revelations, Pinhead is prepared to take Emma to the cenobite realm for having opened the box before other characters explain that she was forced to open it at gunpoint by her boyfriend; Pinhead agrees to let Emma go and take Nico instead.  In his demonic incarnations, Pinhead is irreverent toward Christianity: in the third film, club owner J.P. Monroe exclaims "Jesus Christ," to which Pinhead mockingly replies, "Not quite.", and later on mockingly imitates the stigmata in a church, and states in the fourth "Do I look like someone who cares what God thinks?" In Clive Barker's Hellraiser comics published by BOOM! in 2011, Pinhead has reached a crisis point in his existence and now yearns for spiritual salvation and the opportunity to reach Heaven, and puts into motion a plan to destroy his fellow cenobites as a means of atonement.  Paul T. Taylor, who portrays Pinhead in Hellraiser: Judgment, described the character as "twisted and intelligent". Finding Pinhead's mannerisms and demeanor to be unique among horror icons, Taylor tried to capture that in his performance: "It's about the stillness. He's already so terrifying that when he makes a move, it means something. He's very economical and when he speaks, he's so eloquent." Taylor also incorporated the uncomfortable make-up and costume into his presentation of the sadomasochist, stating "Pinhead's always in agony so he likes it. I feel like I was in character the whole time, and I don't mean that in some sort of artistic, lofty way. I mean I maintained the demeanor the whole time because I had to."

Did he have more than one personality?
