3. The Riddler: Secrets in the Dark
Taking place almost immediately after Batman: Unburied in the same universe, a masked vigilante is going around killing many of Gotham's most famous career criminals. While this isn't exactly shocking, given how Gotham is going to Gotham, the thing that sticks out here is that the victims are high-profile criminals.
Riddler (voiced by Hasan Minaj), back in Arkham Asylum, has been following this case for a while now, baffled and confused by the concept of Batman deciding to take lives when the mystery comes really close to home when he receives a letter from his friend Julian Day, also known as The Calendar Man. It arrives at almost the exact same time that The Calendar Man is murdered by this masked murderer.
Being warned that he's one of the killer's next targets, The Riddler knows he has to escape. Now, on the lamb and pursued by a cop who absolutely wants him dead, The Riddler has to team up with another detective trying to get to the bottom of who this killer is, The Batman himself.
This story features incredible dialogue, exceptional mystery elements, a moving van worth of suspense, and, quite possibly, one of my favorite renditions of Killer Croc outside of Gotham Academy. This character is a love letter to some of Batman's lesser-explored rogues turning even characters like King Tut into fully three-dimensional human characters that you may not like but you definitely care about.
