Jack

Jack Skellington (known as Uncle Jack by Junior and Minnie) is the Pumpkin King of Halloween Town.

Appearance
Jack Skellington is a very tall and lanky skeleton. As always, he appears in a black pinstripe suit, black shoes, and a bowtie resembling a bat.

Personality
As it is in his movie The Nightmare Before Christmas, Jack Skellington is slow to anger and a gentleman at heart. Although he still gets a kick out of scaring people, he's a kind uncle who welcomes Grim's family to his home with open arms.

Jack Skellington demonstrates his selfless nature when he stays to fend off the monster that threatens Halloween Town while Sally evacuates the residents. However, this noble deed is contradicted shortly after when he "regroups" (retreats) with Grim, much to Mandy's frustration.

Sally Skellington
Sally Skellington is Jack's beloved wife and closest friend out of all the Halloween Town residents. They started out as friends and nothing more, but a certain incident involving a Halloween-Christmas time mash-up led them to realize the feelings they had for each other and embrace them.

The Grim Reaper
The Grim Reaper is Jack Skellington's older brother. They appear to be on good terms throughout the story.

Mandy
Mandy is Jack Skellington's sister in-law.

Grim Junior
Grim Junior is Jack Skellington's nephew.

Minimandy
Minimandy is Jack Skellington's niece.
