The Pirate King, a formidable and charismatic antagonist, plays a pivotal role in both the original episode and the Plaza New. Through his character, the writers cleverly subvert traditional notions of piracy and villainy, presenting a multidimensional figure driven by a desire for freedom and self-expression. The Pirate King's interactions with Finn and Jake serve as a catalyst for their development, as they navigate the complexities of heroism, morality, and friendship.

“Creepy,” Finn said, pulling out his demon blood sword. “I love it.”

What makes Pirates of the Enchiridion successful is its respect for the source material. It does not try to be a blockbuster RPG. Instead, it feels like a lost season of the show, complete with bizarre side quests, philosophical villains (a pirate king who just wants to be left alone with his books), and a resolution that hinges on forgiveness rather than violence. The final act, which brings the party face-to-face with the source of the flood, reveals that even the game’s antagonist was acting out of loneliness and confusion—a quintessentially Adventure Time conclusion.
