Technically, it's dudes, buddies and one homie.
This is the guy counterpart to my Girls Girls Girls drawing of Nightmare Before Christmas fancharacters.
Jack, Lock and Barrel are obviously of Tim Burton's creation.
As for the rest
Edgar H. Skellington: (the skeleton with hair in the red suit) Jack's oldest son
Gregor M. Skellington: (The poor he- reanimated ragdoll Edgar is noogieing) Jack's youngest son
Trivette: (the "gangsta skeleton"
Some neighborhood thug that always wants to tag along
Halberd: (the lumpling with the hockey mask laughing at Gregor) Barrel and Hester's son
Caliber: (the young warlock on the bubble) Shock and Hatchet's son
Hatchet: (the warlock in the gray robes) Lock and Edgar's worst enemy. Well, not their worst enemy, but they don't get along too well
Wrath: (The half gargoyle half vampire hybrid) Dusk Kitsune's (owned by Katdakat88) wife. Edgar's nextdoor neighbor and sworn bodyguard.
Chuck Claus (the blond human): Sandy Claws' son
Paul Frost (the blizzard elf): Jack Frost's son
Jason Yulelog: (the toy elf) The least jolly elf in all of Christmas town
