Timeline

This is a timeline of all the various media that make up the Arkham universe. It includes the games: Arkham Asylum, Arkham City, Arkham Origins, Arkham Knight, Arkham Origins Blackgate and the comics: Arkham City, the Arkham City Digital Comic, Road to Arkham Asylum and Arkham Knight. The timeline also functions as a "recommended reading order", and as such does not take flashbacks into account, instead placing issues according to their "present day" sections. Please note that this is a work in progress, and may be incorrect in places.

Note that issues 33-39 (or 11 & 12) of Arkham Knight digital-first comic book series are non-canonical, as the events of the comics don't match information in the game. Bane, for example, has an entirely different fate in the comics than is told in the game.

The third issue of the Arkham Knight: Genesis comic miniseries also depicts a different scenario of how Jason Todd was actually captured by Joker, thus contradicting the Gotham City Story The Fall as shown in the game.
