The Joker is a character in the Batman: Arkham series of video games. He is based on the DC Comics supervillain of the same name, created by Bill Finger, Bob Kane, and Jerry Robinson, and was adapted for a continuity developed principally by Rocksteady Studios. The character debuted in Batman: Arkham Asylum (2009), in which he is voiced by Mark Hamill. Hamill portrays the older version of the character in Rocksteady's main trilogy and Batman: Arkham VR, while Troy Baker voices a younger Joker in the prequels Batman: Arkham Origins, Batman: Arkham Origins Blackgate, and Batman: Arkham Shadow. J. P. Karliak also voices a version of the Joker from an alternate universe in the spinoff game Suicide Squad: Kill the Justice League (2024).
The continuity established by the Batman: Arkham games is often referred to as the "Arkhamverse". The Arkhamverse incarnation is depicted as Batman's archenemy with an increasingly intimate psychological counterpart to him. In Arkham Asylum, the Joker seizes control of the titular institution in a plan to create an army of mutant monsters and attack Gotham City. Batman: Arkham City (2011) centers part of its story on his terminal illness and subsequent death, while Batman: Arkham Knight (2015) reintroduces him as a chemically-induced hallucination representing Batman's fear that the Joker's personality will overtake him. The 2013 prequel to Arkham Asylum, Arkham Origins, instead depicts their first encounter and the beginning of the Joker's fixation on Batman.
Both the Arkhamverse iteration of the character and Hamill's performance received widespread praise. Hamill won the D.I.C.E. Award for Outstanding Achievement in Character Performance for Arkham Asylum and the British Academy Games Award for Performer for Arkham City, while the Joker was named Character of the Year at the 2011 Spike Video Game Awards. The incarnation has also received scholarly and cultural analysis for the way he functions as an antagonist and guide, his relationship with Batman, and his continued narrative presence after death.
Development and portrayal The Joker was created for DC Comics by Bill Finger, Bob Kane, and Jerry Robinson, although the extent of each creator's contribution remains disputed. Robinson said that he conceived a visually distinctive and enduring archvillain for Batman after sketching a joker playing card, while Finger connected the design to Conrad Veidt's portrayal of the disfigured Gwynplaine in the 1928 film The Man Who Laughs, whose fixed grin influenced the character's appearance. The character debuted in Batman #1 in 1940 before being adapted across film, television, animation, and video games.
Batman: Arkham Asylum was conceived as an original Batman story rather than an adaptation of a particular film, comic book, or television production. This gives its developers latitude to combine elements from different versions of the franchise. DC Comics approached writer Paul Dini, who had previously written the Joker for the DC Animated Universe, to devise an original story suited to a video game. Dini developed the narrative collaboratively with Rocksteady's story and design staff, including lead narrative designer Paul Crocker. He described game writing as an iterative process in which story scenes and dialogue had to be repeatedly revised around gameplay and technology. Crocker said the team drew from memorable Batman stories while attempting to reconcile dedicated fans' expectations with broader popular understandings of the characters.
Because of the asylum setting, the Joker was established early as a major part of the first game's story. The developers avoided basing him on a contemporary film portrayal. The character model for this iteration of the Joker as thinner, lankier, and more indebted to the comics than the iteration played by Heath Ledger in The Dark Knight. Dini said that seeing the character models encouraged him to take the Joker into darker territory than in his animated work. Discussing the game's balance of cutscenes, the Joker's announcements over the public-address system, and environmental recordings, director Sefton Hill said Rocksteady used cutscenes primarily to develop relationships and alter the player's understanding of the story rather than to show action unavailable during gameplay. He said each scene was intended to change either the circumstances of play or the perceived importance of the player's actions.
Hamill had voiced the Joker in Batman: The Animated Series and related productions before being cast in Arkham Asylum. The game reunited him with Dini and Batman actor Kevin Conroy, but its intended older audience allowed the creative team to make the character more violent than the television incarnation. Hamill later called the result a "whole new Joker", attributing the difference to the games' darker tone and freedom from children's television standards. Dini similarly said the games pursued a more intense tone than the animated series while retaining characters familiar to Batman audiences.
For the prequel Arkham Origins, developed by WB Games Montréal, Baker replaced Hamill as a younger Joker. The casting prompted comparisons with Hamill because Baker adopted many of the established performance's vocal characteristics. During a 2013 promotional event for Arkham Origins, Baker performed a monologue from Alan Moore and Brian Bolland's Batman: The Killing Joke, a comic closely associated with the character. Baker later reprised the younger incarnation in Arkham Origins Blackgate, the animated film Batman: Assault on Arkham, and Arkham Shadow.
Rocksteady planned the Joker's death in Arkham City relatively early in development. Hill recalled that DC Comics, Warner Bros., and Rocksteady accepted the decision provided it was clear that Batman did not deliberately kill him. The developers instead made the Joker responsible for his own death when his attempt to attack Batman caused the cure to be destroyed; Hill described this as a "poetic" conclusion arising from the Joker's inability to resist betraying Batman. He considered killing such a central character a striking and almost taboo ending. While promoting Arkham Knight, Hill said the death had "huge consequences" for the sequel and reflected Rocksteady's preference for events that permanently changed its continuity rather than returning the story to an unchanged equilibrium.
Appearances The Joker first appears in Batman: Arkham Asylum, in which he permits Batman to return him to Arkham Asylum as part of a plan to seize the institution. After releasing its inmates, he communicates with Batman through the asylum's public-address system and directs him toward a succession of traps and encounters. The Joker seeks to create an army of enhanced followers using Titan, a derivative of the drug used by Bane, and injects himself with it after Batman foils the plan. Batman defeats him after the mutation. The Joker was also made playable in challenge maps in the PlayStation 3 version of the game and the Return to Arkham remastered versions of the first two games.
In Batman: Arkham City, the Joker has been confined within the eponymous mega-prison and is dying as a consequence of his Titan exposure, while fighting for territory and supplies with Two-Face and the Penguin. He infects Batman with his blood and distributes it to Gotham hospitals in order to force him to obtain a cure. He also uses the shapeshifter Clayface as a healthy-looking double. After Batman recovers the cure, the Joker attacks him and inadvertently destroys the remaining dose. Batman tells him that he would nevertheless have saved him, after which the Joker dies laughing. The character's death supplies the premise for the downloadable story Harley Quinn's Revenge, in which Harley Quinn attempts to avenge him.
Batman: Arkham Origins, set earlier in the continuity, presents the Joker as the true organizer of a bounty placed on Batman while he impersonates Black Mask. During their second encounter, Batman saves the Joker from falling to his death. The act fascinates the Joker, who becomes preoccupied with understanding Batman and comes to regard him as a necessary counterpart. A playable sequence set within the Joker's mind depicts his emerging interpretation of their relationship while he is interviewed by Blackgate Penitentiary psychiatrist Harleen Quinzel. The Joker creates a riot at Blackgate and takes over it with Bane's help, before being defeated by Batman again. The same younger incarnation appears as a playable character in Origins' multiplayer mode, and in Arkham Origins Blackgate and Assault on Arkham. Baker briefly reprises the character in Arkham Shadow, set several months after Origins, where the Joker is still imprisoned at Blackgate.
Although physically dead, the Joker repeatedly appears as a hallucination to Batman in Arkham Knight after he is exposed to a combination of the Joker's infected blood and Scarecrow's fear toxin. The apparition torments and manipulates Batman, who fears that the Joker's personality will replace his own. During the final confrontation, Batman overcomes that fear and confines the Joker to a locked corner of his mind.
The character appears again as a psychological projection in Batman: Arkham VR.
Reception and legacy Critical reception Critical response frequently singled out Hamill's performances as the Joker. Kohler wrote that Hamill "runs the show" in Arkham Asylum, observing that the actor had greater freedom to portray the Joker as deranged than in the animated television series. Reviewing Arkham City for Game Informer, Reiner stated that Hamill's performance "couldn't be better". Alessandro Fillari of GamesRadar+ opined that Hamill's work on the Batman: Arkham series is arguably his best as the character.
Hamill's work in Arkham Asylum won Outstanding Achievement in Character Performance at the 13th Annual Interactive Achievement Awards, later renamed the D.I.C.E. Awards. His performance in Arkham City won the British Academy Games Award for Performer, and his return in Arkham Knight was nominated in the same category. The Joker's Arkham City appearance was separately named Character of the Year at the 2011 Spike Video Game Awards.
Reiner described Baker's voice work for Arkham Origins as a remarkably successful recreation of Hamill's voice, while also praising the prequel's exploration of the Joker's developing psychology. He wrote that Arkham Origins became the Joker's game once the character appeared and considered its psychological material the most compelling part of the story. Philip Kollar of Polygon similarly wrote that, although the Joker had served as the principal antagonist of the preceding games, Origins cast new light on him by depicting his first meeting with Batman and exploring his distorted psychology.
Critical response to the character contrasted praise for his voice performance and narrative prominence with criticism of his physical transformation in the climax of Arkham Asylum. Tom Hoggins of The Daily Telegraph and Edge singled out the final confrontation with the Titan-enhanced Joker for what they considered insubstantial gameplay. More broadly, reviewers criticized the game's boss encounters for relying on repetitive and conventional action-game patterns and for failing to match their narrative build-up. Andy Kelly of PSM3 considered the encounters anticlimactic, while Dan Whitehead of Eurogamer criticized the repetition of mechanics already used against lesser Titan-enhanced enemies. Kohler nevertheless positively identified the Joker as the central character of the game, albeit its final hours are weaker than its earlier portions.
