Batman: Arkham - 10 Secrets & Events You Definitely Missed
7. Calendar Man's Monologues - Batman: Arkham City
Calendar Man is a less-than-pivotal villain across the Batman: Arkham series, but one who crops up repeatedly with a number of cool Easter eggs for players. For starters, his cell can be found in Arkham Asylum with a series of torn calendars around the room.
In Batman: Arkham City, visiting Calendar Man in his cell beneath the courthouse in Park Row on certain holidays will see the villain give Batman unique dialogues related to the day. What's more, there's even the Storyteller achievement in place for those players who are able to visit Calendar Man across the 12 separate holidays written in by Rocksteady.
There's also an extra interaction reserved for the company's founding on December 13th, 2004. If players visit the villain on this day, he will remark that he 'was there for the beginning' and 'will be there at your end'. True enough, if players complete Arkham Knight 100%, Calendar Man will briefly be visible when Wayne's manor explodes.
Calendar Man's best moment in Batman: Arkham City is saved for last. If the Dark Knight comes back to Calendar Man's cell after visiting him during the 12 holidays, he will have broken out - leaving a dead Two-Face thug in his place.
