On Christmas Eve, the Guardians and J-Team must fight to save Saint Nicholas from Cedric and Wong before they can unleash Krampus.
- Adaptational Badass: Nicholas is significantly more powerful and skilled than Santa was in JCA canon. The villains need Hak Foo just to restrain him, and even without his magic, he still joins the fight against Krampus, matching the demon with pure muscle.
- Arbitrary Skepticism: Hay Lin calls out the others for not believing in Santa despite all the other magic in their lives.
- Badass Santa: As noted above, Saint Nicholas is so strong the villains need Hak Foo just to give them an edge against him. And even when stripped of his magic by Wong, he can fight Krampus with sheer physical might.
- Brought Down to Badass: When Saint Nicholas has his magic stolen by Wong, he's still powerful enough to fight Krampus purely with muscle-power.
- Chain Pain: Krampus can control chains, which he uses to restrain children.
- Christmas Episode: The chapter's plot is about J-WITCH and the J-Team having to save Saint Nicholas from Wong and Cedric, who are planning to free Krampus.
- Crazy-Prepared: Cornelia brought seeds with her, since plants don't really grow much in the Arctic.
- The Krampus: In this story, Krampus is a demon who once fed on the souls and flesh of children who were corrupted by negative emotions, until Saint Nicholas and his elf allies sealed him away in an Arctic tomb.
- Noodle Incident: Uncle and Yan Lin crossed paths with Saint Nicholas and his elves at some point during Yan Lin's tenure as a Guardian.
- Sealed Evil in a Can: Krampus was long ago sealed in an Arctic tomb by Saint Nicholas and his elf allies, who built their monastery over him to maintain the seal. Wong and Cedric attack the monastery to free him and unleash him on the Guardians, but he's ultimately defeated and re-sealed.
