Although Batman: Arkham Asylum (2009), Batman: Arkham City (2011) and Arkham Knight refer to themselves many times throughout the games as a trilogy, Rocksteady considers the events of Batman: Arkham Origins (2013) canon. Inside the GCPD you can find items belonging to the villains from Arkham Origins, including The Electrocutioner's Shock Gloves, equipment also used by Batman. In addition, Deathstroke and Firefly, who only appeared in Arkham Origins, show up in Arkham Knight and reference a specific moment from Arkham Origins, including their defeat at Batman's hands.

The game's ending references Frank Miller's "The Dark Knight Returns," specifically the destruction of Wayne Manor and the supposed death of Batman/Bruce Wayne. Unfortunately, at the end of the game audiences were left without any closure regarding Batman/Bruce Wayne.

If you listen closely to the background noise when the Joker appears, you can faintly hear echoes of his signature maniacal laugh.

Garfield Lynns/Firefly appears for the second time in an Arkhamverse game. Although Rocksteady does not consider Batman: Arkham Origins (2013) (developed by WB Montreal) part of the Arkham Trilogy, Firefly's continuity is accepted and referenced, with a nod to the bridge where the relevant boss fight takes place in Origins.

Bruce Wayne/Batman, Captain/Commissioner James Gordon, Barbara Gordon, The Joker, Harley Quinn, Killer Croc, Jack Ryder and The Riddler are the only characters who appear in all four Batman: Arkhamverse games. The next group consists of Alfred Pennyworth, The Penguin, Vicki Vale, Quincy Sharp, Black Mask, Bane, Aaron Cash, Victor Zsasz, Poison Ivy and Mr. Freeze, who appear in three of the four games. Alfred, Black Mask, Vicki, Penguin and Mr. Freeze did not appear in Batman: Arkham Asylum (2009). Cash, Zsasz and Ivy do not appear in Batman: Arkham Origins (2013), Bane does not appear in Batman: Arkham Knight, and Sharp does not appear due to his suicide between this game and Batman: Arkham City (2011). It should be noted that Jack Ryder is only heard over the radio in Batman: Arkham Asylum, that Barbara Gordon is only heard talking to Batman in Batman: Arkham Asylum and Batman: Arkham City, that Alfred is likewise only heard in Batman: Arkham City, that the Joker appears in Batman: Arkham Knight only through hallucinations, that Mr. Freeze appears as DLC missions in Batman: Arkham Origins and Batman: Arkham Knight, and that Killer Croc appears in DLC and, in some cases, in hallucinations, while Zsasz briefly appears as an easter egg.

When the Arkham Knight appears with the drill machine, he says that the line "I did ask if it came in black, but then I thought: nah you'd just get all jealous" is a reference to the Dark Knight Trilogy, in which Bruce Wayne frequently asks whether tools and vehicles "come in black?"

Various wanted posters in the GCPD Headquarters give clues to the game's developers. One example is Alick Goldenberg. Each poster contains a crime description that also describes their traits, along with humorous explanations.

Regarding Henry Adams' disappearance: * On top of the refrigerator in Pauli's Diner there is a notice stating that a local man named Henry Adams has gone missing. Of course, it is later revealed that he was abducted by Batman himself; as the only blood transfusion recipient with a natural immunity to the Joker's blood, he was instrumental in Batman and Robin's attempts to synthesize a cure. * Among all the Jokerized citizens, Henry is the one whose physical appearance most resembles the real Joker; so much so that, without the skin or hair color, he almost looks like he could be an older relative. It turns out there is a hint that he is the most Joker-like of them and ultimately was not exempt from the condition. * When Batman asks him for help hacking a security camera, a hint emerges that Henry (and the person hacking the security system) was not initially as immune as believed. He does not neglect to tell Batman that he really knows nothing about computers before starting to do what Batman asked much faster than someone who is truly not computer literate could be expected to. He notes that the interface is much simpler than a normal computer layout, but in hindsight this seems like a kind of mockery. Similarly, billboards for the cocktail singer Johnny Charisma's live Halloween show are seen all over the city. Although some fans' initial comments about a hidden message note seemed strange, it later turned out to be correct to some degree; Johnny, another infected blood recipient, gradually comes to resemble the Joker, complete with a similar hairstyle and an equally flamboyant lizard costume. Batman later even hallucinates variations of the billboard in which the host of the show is the Joker.
