Mr. Stiks is one of the monsters of Halloween.

Stiks is a poorly-built marionette that was granted life by the Moon Twin. Stiks believed that he was shunned because he had no hands or feet, and asked Basphomy for help. She convinced him to murder his maker and steal his extremities. Because of his evil, Stiks' body was cursed to constantly waste away, forcing him to find new replacement parts[1]. Stiks proved instrumental in Bun-bun's attack on Thanksgiving, stealing the head and wings of a turkey to smuggle Bun-bun into the castle[2].

Recently, Mr Stiks was said to have released Basphomy from the Obsidian Cage[3].
