Prepare for an epic crossover event, with a not-so-jolly St. Nick descending upon Gotham City! His cheerful demeanor has been replaced by a grim determination to investigate a brutal crime that has shaken the city in the days leading up to Christmas. With the help of his former student, the iconic Batman, Santa will unite with the heroes of the DC Universe, including the legendary Justice League, to right this wrong—or the world will wake up to coal in their stockings! And when Krampus arrives, releasing monsters to destroy the holiday, Santa Claus and the Justice League stand as the only beacon of hope. This is not your typical holiday tale but a brutal, two-fisted narrative of hope, wonder, and monster hunting that will keep you on the edge of your seat—it's Claus in canon! Collects issues #1-4
