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.
Described by Doug Bradley as stronger than Jason Voorhees and Michael Myers, Pinhead is an extremely powerful being, and as such, has several supernatural abilities. His preferred method of attack is by summoning hooks and chains to mutilate victims, often pulling said victims in several directions to tear them apart. These chains are subject to his total mental control and he may direct them at will. The chains may even change shape after having attached to a victim. Pinhead is highly resistant to damage and direct assault, being able to resist both gunshots and futuristic energy weapons. His magic is also used for creating objects out of thin air, teleporting, creating explosions at distances and deceiving opponents with illusions. He is capable of creating other cenobites from both living and dead victims. In order to act in the physical world, Pinhead needs to have been purposely summoned through the Lament Configuration, though this in itself is not usually enough for Pinhead to target the puzzle-solver: in Hellbound: Hellraiser II, Pinhead stops the Cenobites from torturing an emotionally traumatised girl who was manipulated as a proxy into opening the Configuration, remarking "...it is not hands that call us, it is desire." In Hell on Earth, he temporarily eliminates these restraints when he is separated from the part of him that is Elliot Spencer, wreaking havoc indiscriminately upon every human subject he encounters until he is finally defeated when Spencer willingly merges with Pinhead once again, the combination binding Pinhead as Spencer keeps his extremes in check. During this incident his powers were apparently expanded beyond their normal limits allowing him to physically warp reality to his will. Pinhead at first has no memory of his human past, though is reminded of it in Hellbound: Hellraiser II, which results in what screenwriter Peter Atkins described as him being "spiritually weakened" and subsequently killed by the Chanard Cenobite.

What was Pinhead's weaknesses?

Answer the question at the end by quoting:

Caesar was the youngest of three sons born to Jewish immigrants living in Yonkers, New York. His father was Max Ziser (1874-1946) and his mother was Ida (nee Raphael) (1887-1975). They likely were from Dabrowa Tarnowska, Poland. Reports state that the surname "Caesar" was given to Max, as a child, by an immigration official at Ellis Island.
After graduating from Yonkers High School in 1939, Caesar left home, intent on a musical career. He arrived in Manhattan and worked as an usher and then a doorman at the Capitol Theater there. He was ineligible to join the musicians' union in New York City until he established residency, but he found work as a saxophonist at the Vacationland Hotel, a resort located in the Catskill Mountains of Sullivan County, New York. Mentored by Don Appel, the resort's social director, Caesar played in the dance band and learned to perform comedy, doing three shows a week. He audited classes in clarinet and saxophone at the Juilliard School of Music. In 1939, he enlisted in the United States Coast Guard, and was stationed in Brooklyn, New York, where he played in military revues and shows. Vernon Duke, the composer of Autumn in New York, April in Paris, and Taking a Chance on Love, was at the same base and collaborated with Caesar on musical revues. During the summer of 1942, Caesar met his future wife, Florence Levy, at the Avon Lodge in the Catskills village of Woodridge, New York. They were married on July 17, 1943, and had three children: Michele, Rick and Karen. After joining the musicians' union, he briefly played with Shep Fields, Claude Thornhill, Charlie Spivak, Art Mooney and Benny Goodman. Later in his career, he performed "Sing, Sing, Sing" with Goodman for a TV performance. Still in the service, Caesar was ordered to Palm Beach, Florida, where Vernon Duke and Howard Dietz were putting together a service revue called Tars and Spars. There he met the civilian director of the show, Max Liebman. When Caesar's comedy got bigger applause than the musical numbers, Liebman asked him to do stand-up bits between the songs. Tars and Spars toured nationally, and became Caesar's first major gig as a comedian. Liebman later produced Caesar's first television series. After the war, the Caesars moved to Hollywood. In 1946, Columbia Pictures produced a film version of Tars and Spars in which Caesar reprised his role. The next year, he acted in The Guilt of Janet Ames. He turned down the lead of The Jolson Story as he did not want to be known as an impersonator, and turned down several other offers to play sidekick roles. He soon returned to New York, where he became the opening act for Joe E. Lewis at the Copacabana nightclub. He reunited with Liebman, who guided his stage material and presentation. That job led to a contract with the William Morris Agency and a nationwide tour. Caesar also performed in a Broadway revue, Make Mine Manhattan, which featured The Five Dollar Date--one of his first original pieces, in which he sang, acted, double-talked, pantomimed, and wrote the music. He won a 1948 Donaldson Award for his contributions to the musical.
