By making Damian the central character, Merry Little Batman Flixtor effectively addresses any grievances and relegates the Caped Crusader to a supporting role. Throughout the movie, the spirited Bat-kid constantly tests Alfred's patience and embarks on adventures with Selina the cat. Despite the absence of any playmates, such as Robin, Damian's determination remains unshaken. As the Joker returns to Gotham with a gang of villains, determined to ruin the city's Christmas, Damian's dreams of becoming Gotham's sole protector come true, resulting in an exhilarating holiday adventure.
