Jack discovers Christmas Town and decides that this new experience is what his life was missing. He makes plan for his own Christmas celebration in Halloween Town and wants to impersonate Santa Claus in the real world. While his intentions are not malicious, Jack does not understand the true spirit of Christmas. Halloween Town plans to give the holidays a macabre make-over. Sally reveals to Jack a bad premonition, but Jack’s basic nature is impulsiveness. He does not seem to register contradictory information. By the end of the film, he notices Sally and her determination to help him. He proves that love can be a part of his nature by calling Sally his “Dearest Friend”, telling Sally that they were meant to be together, embracing his future with her and embracing her.
Jack follows the formula of a tragic hero, because he begins the story at a lofty position. In spite of all his fame and talent, he yearns for another side of life. While a desire for completeness is not a flaw, his impulsiveness proves to be. He tends to be enthusiastic and inclusive, and his charisma is enough to sway every member of Halloween Town except Sally. His selfish decisions lead to the near destruction of Christmas and himself. The strength of Jack’s character is demonstrated by his will to correct his own mistakes.
