Sally

Sally is Jack Skellington's girlfriend (technically speaking). She is a character in all Kingdom Hearts games. She was created by Dr. Finkelstein. Her limbs are sewn on, and they fall off sometimes. She usually has to sew her limbs back on. She is always the voice of reason to Jack, even though he doesn't listen to it sometimes. She is intuitive, and can tell when things that Jack is planning are going to turn out wrong. Sally is one of the main characters in The Nightmare Before Christmas.

Trivia

 * Sally is compared to Kairi by Goofy because they have similar personalities.


 * While it is repeatedly implied that Sally loves Jack, it is unknown if the affection is also from Jack to Sally. From his actions in the Kingdom Hearts series, it might seem that Jack only sees Sally as a friend. However, their relationship develops drastically in Kingdom Hearts II as in this game, they are seen dancing together at the end of the story, which reminds Sora of Kairi. Jack did however say to Sally that she didn't even have to ask for them to be together, meaning he returns the feeling she has for him.
