The Pumpkinheaded King of Halloween became the patron of Halloween after Basphomy. The Pumpkinheaded King, a parody of Jack Skellington, is somewhat light-hearted in his terrorizing, as opposed to the cruel and more sinister Basphomy. The land of Halloween is separated from the rest of the world by the Obsidian Gate. As his name implies, the King's head is a constantly changing carved pumpkin, rendering him immune to weapons that slice and puncture (like switchblades and glocks, Bun-bun's weapons of choice), but leaves him prone to bludgeoning weapons, like Basphomy's mallet. He was the first intentional victim of Bun-bun's war against the holidays, but was restored to life when Bun-bun used the last Deus Ex Ovum. At the start of the war, the Pumpkinheaded King of Halloween cared for Kiki for a few months, and proved himself to be the worst bedtime storyteller ever.
Right before his death, he offered her the right to claim the holiday of Easter from Bun-Bun, who in turn implicitly offered her Halloween in the future but she regretfully chose to stun him with her spook ability while Bun-Bun smashed his pumpkin head with her mallet.
During the war, Bun-Bun had said that if Santa used the last Deus Ex Ovum, Basphomy would be returned to her previous status "under" the Pumpkinheaded King rather than Basphomy herself being restored to patron status. All that was completely confirmed about him was that, at the end of the war, when the third egg was used, the Pumpkinheaded King was returned to life, with Father Time's narration, "SOME HOLIDAY ICONS WERE RETURNED FROM THAT ETERNAL SLUMBER," alongside the Easter Bunny and General Gohblair.
