SkellingDort

SkellingDort is the slash ship between Jack Skellington and Victor Van Dort from the The Nightmare Before Christmas and Corpse Bride fandom.

Canon
Since they are from different movies, Jack and Victor never meet in canon. However, their respective films agree that both were created by Tim Burton, so they have a similar spooky aesthetic. Their designs are aesthetically similar in themselves, having the same black and white color palette, very white skin and a black suit.

The plot of their respective films occurred when they were in a forest, where Victor he met Emily and Jack ended up in Christmas Town. The two also agree that they are accompanied by an undead dog, Zero and Scraps respectively.

However, in terms of personality, Victor and Jack do not have much in common, not to mention that they are very opposites. Jack has a lively, happy personality, he is very sure of himself and loves to scare, contrasting with the shy and scared personality of Victor.

Fanon
Along with the crossover between The Nightmare Before Christmas and Corspe Bride in general, people started drawing Jack and Victor together as soon as Corspe Bride was released. Although many couples have been created for this crossover, this is considered one of the main ones, along with Jack/Emily and Sally/Emily. The idea of shipping them romantically comes from fans of Jack who wanted a slash ship for him but find difficult to ship him with any character from their movie on behalf of Sally, and they saw Victor as a profitable option.

It helps that the two have such different personalities, making people think they would have a fun dynamic. People like to imagine how they met, thinking that Jack maybe it would tease Victor with their scares. A common setting for the ship is Corpse Bride AUs in which Jack takes the role of Emily. Other settings mix the plot of both films a bit, making Jack fall and become excited about the human world instead of the Christmas Town, and meets Victor. However, since they both have love interests, some people prefer them to be just friendly.

There is also a very famous theory that the two of them are the same person. This theory usually includes Victor Frankenstein of Frankenweenie, as he looks very similar and directly shares a name with one of them and also has an undead dog. According to this, Victor travelled through time and was trapped in the 19th century with his dog, being adopted by the Van Dorts. After the events of Corpse Bride, Victor began to get excited about Halloween after discovering the world of the dead and began to visit them often. When he died, he lost his memory, changed his name and his dog's name and became the Pumpkin King. For this reason, some people consider that the three films are telling the entire life of a single character.

Another less common headcanon is that they are brothers, with Jack being Victor's dead older brother. Eventually, people who ship them romantically prefer to ignore these theories.
