The Batman: Arkham Knight comic book is a weekly comic that tied-in and acted as a prequel to the Batman: Arkham Knight video game.
It takes place in the intervening months between the end of Batman: Arkham City and the beginning of Batman: Arkham Knight. It follows a varied cast of heroes and villains, including those from previous games and some characters that hadn't yet made an appearance in the Arkhamverse but may well be familiar to fans of the wider DC franchise, such as Metamorpho. It also introduces brand new characters to the Arkhamverse such as Zimmer, the builder of the various Batmobiles; Kid Shark, son of the deceased Suicide Squad member King Shark; and Tweedledie, a genetically engineered cousin of Tweedledum and Tweedledee. It also kills off several characters not set to appear in the finished Arkham Knight Game or its DLC.
The main plots revolve around Bruce Wayne's Gotham Reborn project - an attempt to rebuild Arkham City and reintegrate it with the rest of Gotham; James Gordon's mayoral campaign; and the Arkham Knight's long laid-out plans beginning to come to fruition.
Though the comic is served as a prequel some elements are considered Non-Canon as they contradict events that happen in the Batman: Arkham Knight video game.
After its publication later in the year, this comic series ran concurrently with the Batman: Arkham Knight - Genesis miniseries.
The first issue was released on March 11 2015.
