Specials
In the 1990s, writer Jeph Loeb and artist Tim Sale collaborated on three Halloween specials collected as Batman: Haunted Knight that led them to create Batman: The Long Halloween as stated in the Introduction to the book by Jeph Loeb. The three specials are titled Choices (1993), Madness (1994) and Ghosts (1995). In the last, based on A Christmas Carol, Bruce is visited by three spirits on Halloween, that of Poison Ivy (the spirit of Halloween Past), The Joker (the spirit of Halloween Present), and a cloaked, skeletal version of Batman (the spirit of Halloween Yet To Come). Having been immersed so much in stopping crime for nearly two years (the time being Year Two in which the story takes place), Bruce undergoes a change, much like Ebenezer Scrooge, in which he is reminded what it is to be human.
