Jack Skellington is the lead character in the Disney film Tim Burton's The Nightmare Before Christmas. Jack is the "Pumpkin King" of Halloween and lives in a fictional world based solely on the holiday called Halloween Town. His usual appearance is a skeleton dressed in a black pin-striped suit and a bow tie resembling a bat, but there are some points in which he dresses as a scarecrow with a pumpkin for a head. His name is a pun on skeleton. He has a pet ghost dog named Zero, who has a small glowing nose that looks like a Jack-o'-lantern. His love interest is Sally, a rag doll created by Dr. Finklestein. Jack is voiced by Chris Sarandon, and his singing voice is provided by Danny Elfman.
The character is a popular design on bags, hats, clothing, umbrellas, belt buckles, pet collars and other items. According to Ultimate Disney.com's Top 25 Heroes, Jack is #25.
It appears that Jack, being undead, may be immortal; and may or may not feel physical pain. At the climax of "This Is Halloween", he sets himself on fire without serious injury. He also has the ability to remove bones from his body. Jack can take off his head (to apparently "recite Shakespeare quotations") and remove ribs to play fetch with his dog Zero. Despite this inability to feel pain, Jack reacts negatively when Sally accidentally pricks his thumb with a needle.
After being shot by the U.S. military, everyone in Halloween Town believes Jack was "blown to smithereens" and he does appear dead until Zero places his jaw in the right place. He also mentions in the subsequent song that remaining in a cave for million years would turn him to dust, hinting that he may not be immortal and will one day wither away.
