Calendar Man
Now, now – before you assail me with questions about why Calendar Man (of all people) deserves his own Most Wanted mission, allow me to encourage you to read Batman: The Long Halloween. In its pages, we are introduced to a far more creepy and sinister Calendar Man, heavily inspired by Hannibal Lecter. This incarnation was carried into the games up until Arkham City. Here, he is a hulking muscle-bound, but highly intelligent and psychopathic, behemoth with an indiscriminate taste for blood. However, the extent of your interactions with him is limited to Easter Eggs and references, or interacting with him behind panes of reinforced glass regaling tales of holiday-centric serial killings.
By the end of Arkham City, the Calendar Man was revealed to have escaped from his prison cell underneath the courtroom. Considering how Rocksteady Studios has consistently shown an attention to detail in wrapping up mysteries set in motion long before it is only fair that Calendar Man has his moment to shine. Arkham Knight already provides the perfect set-up as it takes place on Halloween night. The Calendar Man would use this opportunity to create his magnum opus of crime to top even the Scarecrow – perhaps he engages in a murder spree all across the city leaving behind calling cards or trophies alluding to classic Halloween myths and traditions. True to his maxim in The Long Halloween, the Calendar Man refuses to be forgotten.
