Zero is Jack's ghost-dog and the tritagonist of Tim Burton's The Nightmare Before Christmas. Zero has a glowing pumpkin nose, an obvious Halloween pun of Rudolph the Red-Nosed Reindeer. Zero helps guide his master Jack Skellington through the fog on Christmas Eve. Zero has a doghouse gravestone seen before Jack enters the highlands.
In the movie, Jack finds the door to Christmas Town while he is taking Zero for a walk. Later, when Jack wants to take off to deliver presents, Zero has to light the way because of the thick fog, similar to Santa and Rudolph. At the end of the movie, Jack and Sally kiss each other as Zero looks at them and flies into the air, transforming into a star.
- Interesting enough, it is implied in the movie that Zero still needs to breathe, as when you see him asleep in his basket in Jacks tower, part of his sheet-like body around his chest moves up and down.
- When Zero is happy, he can wag his "tail", or flip in circles happily.
- The most memorable quote in the entire movie is when he says "E".
