In 2015, with Todd Casey, Zach Shields and Marc Andeyko, Dougherty co-wrote and created a comic book tie in to Trick 'r Treat, titled Trick 'r Treat: Days of the Dead. It featured four new short stories, spanning centuries, depicting a variety of characters and cultures, going back to the holiday's roots in ancient Ireland. Later that year, with Casey, Zach and Laura Shields, Dougherty published a tie-in to Krampus, titled Krampus: Shadows of Saint Nicholas. It features three stories which expand the mythology of the Krampus.
