Jack Skellington, wearing his 'Sandy Claws' suit

Jack Skellington is the "Pumpkin King" and the ipso facto leader of the Holiday World known as Halloween Town. He is responsible for coming up with new and exciting ideas for each year's Halloween festivities, as well as being Caelan's father figure and commander. He first appeared in Tim Burton's beloved classic, The Nightmare Before Christmas. Jack is shown to be incredibly eccentric, always alive and active. He is somewhat of an optimist; when he puts his mind to something, he will not stop until he achieves it. He tends to be slightly oblivious and never thinks things through, which usually leads to disaster which he never intends. However, he is a generally cheerful character who is greatly respected by all, with the exception of Oogie, who despises him with literally every fiber in his body. Being bored with his usual Halloween shtick, Jack goes for a walk in the woods and uncovers the Holiday World nirvana known as Christmas Town. Amazed by its magic, he decides to take over Christmas with...less than expected results, but he eventually saves his ragdoll girlfriend, Sally. Jack is an extremely thin and equally tall being, his legs being over twice as long as his torso. He is a skeleton, and so his head lacks hair and sports empty eye sockets and nostrils. Strangely, his neck is solid, not showing vertebrae segmentation. His skull is similar, showing no distinction between his upper and lower jaws. His mouth is thin and wide, marked by a number of small "seams", similar to a Glascow smile. Jack is missing several teeth in a number of different places. Unlike his head and neck, Jack's hands do show joints. Jack's usual attire is a macabre black suit with white pinstripes. The top has a single white button, and a white shirt is visible underneath. His black dress shoes are bizarrely small in comparison to the rest of his body. The coat tails of Jack's coat reach to about knee-length, and he wears a large, black bow-tie shaped like a bat with several white veins in its wings and white eyes. When masquerading as Santa Claus (as depicted above), Jack dons an obviously fake white beard (the part of the beard that should attach to his chin dangles a few inches from it) that reaches to the top of his thighs. His faded red pants have a vertical seam on the front, and his black, knee-high boots have fur lining at the top. Jack's tails in this outfit are about the same length as his normal ones, and he wears a maroon belt around his waist. His long sleeves are also fur lined at the cuffs. Finally, his faded red Santa hat also has white fur lining around the rim and a white fur ball at the tip. Because of Jack's extreme height, he doesn't need to run to keep up with Caelan. Instead, he is seen speed-walking throughout the stories.
I do not own Jack Skellington. Disney/Touchstone does.
