Arkham Asylum

Arkham Asylum, better known as the Elizabeth Arkham Asylum for the Criminally Insane, is a fictional psychiatric hospital north of Gotham City. It has featured prominently in the various continuities of the DC Universe, as well as in the films Batman Forever, Batman & Robin, and Batman Begins. Depicted as a remote, labyrinthine stone facility, Arkham has housed many of Batman's most notorious foes, including the Joker, Two-Face, Scarecrow, and Killer Croc. Jeremiah Arkham is the asylum's current director.

Etymology and concept
Within the Batman mythos, Arkham Asylum was named for the mother of Amadeus Arkham, a Gotham psychiatrist who founded the institution after his mother's mental illness led to her untimely death&mdash;in reality, Amadeus had euthanized her, although he repressed that memory. According to Batman Unauthorized: Vigilantes, Jokers, and Heroes in Gotham City, a compilation of contemporary analyses edited by Dennis O'Neil, the asylum was named for a somewhat similar facility known as "Arkham Sanitarium" mentioned in the horror fiction of Howard Phillips Lovecraft. As a result, DC's Arkham was supposed to mirror Lovecraft's dark and brooding literary characteristics while providing an essential intertextual supplement to the background atmosphere of equally dismal Gotham City.

Arkham Asylum first appeared in October 1974 in Batman #258, written by Dennis O'Neil and pencilled by Irv Novick. At this point it was simply described as "Arkham Hospital" and implied to be somewhere upstate, in a rural setting. Nevertheless, in Batman #326 writer Len Wein described the asylum as being "deep in the suburbs of Gotham City". Arkham's fictional history was not established until 1985, during an issue of "Who's Who in the DC Universe", also penned by Wein. For several years thereafter it existed as little more than a storytelling device used by writers as a temporary confinement for Batman's deranged Rogues Gallery, making only brief cameo appearances when supervillains were incarcerated or re-incarcerated there. Occasional breakouts from Arkham were often referenced by supporting characters such as James Gordon, whose exasperation at the asylum's obvious security maw finally led him to criticize it as a "revolving door" for its denizens.

Arkham's rather simplistic portrayal was first challenged by Arkham Asylum: A Serious House on Serious Earth, in which Grant Morrison introduced the concept of using the Arkham setting to explore the psychology behind Batman and members of the Rogues Gallery. Arkham Asylum: A Serious House on Serious Earth has since been followed by a number of similar storylines which focused exclusively on the facility and its fictional dynamics, including Arkham Asylum: Living Hell and Arkham Asylum: Madness.

Fictional History
According to Arkham Asylum: A Serious House on Serious Earth, the crumbling Victorian mansion at the heart of the original Arkham Asylum was a single-family home, occupied at the beginning of the twentieth century by the Arkham family. Arkham Asylum: Living Hell elaborates on this information, disclosing that the actual structure was built long before the early 1900s as the "Gotham House of Madness and Ill Humors". The grounds were owned by an occult expert named Jason Blood, who carried out exorcisms on the mentally ill. His patients hailed predominantly from Gotham's poor and superstitious townships, where psychiatric disorders were regarded as synonymous with demonic possession. Blood kept his charges starved and confined to suspended cages, even murdering some in an attempt to obliterate their evil spirits. Blood later sealed up the basement to keep the spirits imprisoned. The House of Madness and Ill Humors was closed down, and the land itself sold to the Arkhams.

After the death of Elizabeth Arkham's unnamed husband, she was cared for by their son, Amadeus. Elizabeth was plagued by dementia and perpetually bedridden; at some point Amadeus told others that Elizabeth had slashed her own throat, but in reality he'd done so when she became too much for him to handle on his own, then repressed memories of the murder. Following Elizabeth's apparent suicide in 1920, Amadeus, now an aspiring psychiatrist, inherited the house&mdash;which he dedicated to accommodating those suffering from serious mental illnesses, as had Elizabeth. Of particular interest to Amadeus was his onetime patient Martin "Mad Dog" Hawkins, a serial killer who raped and sexually mutilated his victims. Arkham felt compassion for Hawkins, whom he perceived as being trapped in the penal system with no hope for proper psychiatric treatment. Construction on the new Elizabeth Arkham Asylum for the Criminally Insane began the following year with the stated goal of providing such an alternative for mentally ill offenders. As the necessary renovations to the Arkham home began in earnest, Amadeus moved his wife Constance and daughter Harriet to neighboring Metropolis, where he temporarily treated Hawkins and his other patients at the state psychiatric hospital. He returned to Gotham on multiple occasions to oversee work on the new asylum, though on one such occasion "Mad Dog" Hawkins escaped. Arkham was consulted during the manhunt by the Metropolis police and prison authorities, but the felon was not successfully recaptured.

As work on the asylum neared completion, Arkham moved his family back to Gotham, unaware that he was being stalked by Hawkins. He arrived home in April 1921 to discover Hawkins had raped and murdered both Constance and Harriet, even leaving his nickname carved on Harriet's fresh corpse. Although seemingly detached from their deaths Amadeus was in fact permanently unhinged by the incident, which further ushered his descent into madness. Hawkins was tracked down by the Gotham City Police Department (GCPD), and when Arkham Asylum opened its doors in November 1921 he was committed as its first inmate. Arkham personally treated "Mad Dog" for several months without incident, but on the anniversary of his family's murder he suffered a psychotic break and executed Hawkins during a faux electroshock therapy session. The GCPD ruled it an accident. Arkham's mental state continued to deteriorate until 1929, when he was convicted of killing his stockbroker, and became a ward of his own hospital.

Since the 1920s, Arkham Asylum has been destroyed, usually violently, on multiple occasions and rebuilt or expanded; for those patients with unique security or health considerations, customized facilities have been installed at considerable expense, such as a refrigerated cell for Mr. Freeze. The asylum has continued to grow larger and more modern in appearance, although as the lion's share of the budget is devoted to security treatment options have inevitably suffered. Despite the installation of advanced technological security measures in the era of metahuman criminals, the inmates have still been able to escape or take control of the facilities from time to time. Director Roger Huntoon was the last known administrative head prior to Jeremiah Arkham; during his tenure Arkham was rocked by ruinous scandals, including one daring escape by the Joker during the events of Batman: The Killing Joke that involved his replacement with a body double, and another in which Abattoir infiltrated a cleaning company Huntoon had contracted to launder the linens. Huntoon made a number of changes to his security policies, including the installation of an anti-riot system that flooded the cell block corridors with gas in the event of a mass disturbance, and permitting guards to carry handguns, to little avail. Despite these shortcomings, his regime developed an excellent working relationship with Batman; on several occasions the Dark Knight contacted Huntoon directly to arrange interviews with various patients. (Detective Comics #628)

Shortly before the aforementioned affair with Abattoir came to light, Roger Huntoon confirmed his retirement and named a member of the Arkham family as his likely successor. This proved to be Jeremiah, nephew of Amadeus Arkham and a psychiatrist of some questionable scruples himself. Jeremiah's first act as new director was ordering the entire facility demolished and completely rebuilt. During the demolition process, he had the old files, including his uncle's diary, disposed of in a symbolic bonfire. The new Arkham Asylum adopted a similar facade to the former Arkham ancestral home, but there the resemblance ended: the inmates were now held in a sprawling, circular, complex which imitated a classical labyrinth. Jeremiah also introduced a new fixture in the form of glass observation walls for the cells, which robbed the patients of some former privacy but allowed convenient round the clock observation. For his own safety and the safety of the staff, interviews were no longer conducted in the same room with violent inmates, except through the glass barriers or in rooms fitted with specialized isolation boxes. (Batman: Shadow of the Bat #3) Batman was forced to infiltrate the new institution as an inmate to learn how another prisoner, Victor Zsasz, was escaping his cell by night and committing crimes in Gotham. Jeremiah would later pit the other inmates against Batman as part of an intense psychiatric study. Mere months later, this incarnation of Arkham Asylum was destroyed by Bane, who unleashed the inmates to weaken Batman. Recapturing the escapees took Batman weeks and left him physically and psychologically drained. Municipal authorities were forced to house former Arkham patients at Blackgate Penitentiary until the damage from Bane's attack could be repaired. Arkham Asylum's second location was discovered inadvertently by the Joker, who stumbled upon the old Mercey Mansion, situated on Mercey Island off Gotham's northern shoreline. This reclusive, multi-storey gothic manor was constructed by Eric Mercey, a Gotham socialite who'd made his millions in the cement business, and had been abandoned for about ten years when the Joker arrived. It housed Mercey's own personal theater and a series of formerly luxurious gardens. When Batman tracked down and defeated the Joker once more, Jeremiah Arkham arrived on the scene with police to take custody of his patient. He was thoroughly enamored of the Mercey Mansion and believed that with its remote location, it would make an excellent site for yet another reconstructed Arkham Asylum. (Batman: Shadow of the Bat #38)

A few years following its second reopening, Arkham Asylum endured another crisis when the federal government cut off support to Gotham City, which largely descended into gang violence. Cells were opened by the deserting staff, their inmates freed, and the institution closed for a year. Jeremiah Arkham was persuaded to disable the security controls and permit the patients to leave the island in exchange for his life, although the Joker stayed behind to set the facility ablaze. In the novelization to Batman: No Man's Land, he and Harley Quinn briefly continued residing there of their own free will. Around this time it is disclosed that Batman had established one of several temporary Batcaves on Mercey Island, known as the "Northwest Batcave".

Super-powered heroine Black Orchid was persuaded to visit Arkham upon her rebirth and quest to discover her identity, seeking information from Poison Ivy. She was disgusted by what she perceived as a desperate place where the patients dwelt in terror, condemning the asylum as "tottering" and "obscene". The staff are less than helpful, forcing her to seek assistance from Two-Face and the Joker, who are restrained in a common room but otherwise unsupervised. Lower risk patients such as the Mad Hatter wander the corridors freely; it is Hatter who finally guides a disoriented Orchid to Ivy's cell.

During Batman's disappearance in the Final Crisis, a new Black Mask liberates Arkham Asylum's inmates and declares himself their new leader before destroying the asylum with a controlled explosion.

In Batman: Battle for the Cowl, Jeremiah Arkham wanders among the remains of the asylum as he contemplates his life. He reveals that he has discovered blueprints created by Amadeus for a new Arkham Asylum. He also contemplates the fates of his own nonviolent, "special" patients: an artist with almost no facial features who must paint facial expressions onto his almost blank face to express himself; a man obsessed with his own reflection in a series of mirrors in his room; and a woman supposedly so ugly, one glance at her face would drive anyone insane. Upon discovering his "special" patients (unharmed from the destruction thanks to their secluded cells), Arkham resolves to rebuild the facility according to his ancestor's vision, but to serve as a literal asylum for mentally ill patients in order to shelter them from the outside world. However, when told to be happy with the new development, the artist secretly paints his face white with a hideous grin, reminiscent of the Joker; it is implied that the "special" inmates, as well as Arkham himself, have given in to madness.

In the Arkham Reborn mini-series, Arkham Asylum is rebuilt and financed by Dr. Arkham, according to his uncle's specifications. However, he is soon exposed by Batman as the new Black Mask and committed on the orders of the new director, Alyce Sinner. It was also revealed that the "special" patients were figments of Arkham's imagination. Sinner's regime proves far more corrupt than Jeremiah's; she is revealed to have actively worked with both Black Mask's organization and the sinister Church of Crime.

Less than a year later, Arkham Asylum was severely damaged as part of a supervillain assault on Batman, and collapsed following an explosion triggered by the Spectre. (Batman Eternal #29) Simultaneously, Wayne Enterprises loses most of its assets due to a conspiracy by Hush and Bruce Wayne is forced to file for bankruptcy. Wayne Manor is seized by the state and selected as the site for Arkham's latest incarnation, and Batman accepts the situation on the pretext that he can now keep a closer eye on his Rogues Gallery due to his intimate knowledge of the building. (Arkham Manor #6)

Other versions
A somewhat apocryphal account is given for Arkham Asylum's founding in Batman Confidential #9, which claims that the facility was known as Arkham House and designed by a relatively unknown psychiatrist, Jonathan Crane, for housing what he describes to Batman as "a new breed of villain". Crane's plans to renovate and reopen Arkham House reach fruition when a crime spree by the Joker provides the impetuous needed for the city council to approve them.

The Dark Knight Returns, written by Frank Miller, takes place about 10 years after Batman "retires." It depicts an "Arkham Home for the Emotionally Troubled", presumably a renaming of the asylum which occurs as a result of changing attitudes towards mental health. The Joker is housed there, catatonic since Batman's disappearance, but awakens when the vigilante resumes action. Under the employ of the home is Bartholemew Wolper, a condescending psychologist who treats the Joker humanely, even going so far to arrange for him to appear on a late night talk show, while arguing that Batman himself is responsible for the crimes his enemies commit by encouraging their existence; Wolper is killed when the Joker uses his lethal gas on the talk show audience.

In Miller's sequel The Dark Knight Strikes Again, it is revealed that the patients have taken over the secluded institution and have resorted to cannibalism. Plastic Man is one of the more notable patients in this version of Arkham Asylum.

During the non-canon JLA: The Nail, the Joker, using Kryptonian gauntlets provided by a genetically augmented Jimmy Olsen, breaks into Arkham, erecting a forcefield around it that prevents anyone but Batman, Batgirl and Robin from entering, while forcing the rest of the patients to fight each other for an opportunity to serve him. Catwoman wins the resulting conflict shortly before Batman breaks into the asylum, but the Joker's gauntlets allow him to capture Batman, forcing him to watch as the Joker brutally tears Batgirl and Robin apart in front of him. Although Catwoman manages to distract the Joker long enough for Batman to escape and damage his gauntlets, the grief-maddened Batman subsequently beats the Joker to death on the asylum roof before the entire building collapses, apparently killing most of its remaining inmates.

In Batman: Crimson Mist, the third part of the trilogy that began with Batman & Dracula: Red Rain, a vampiric Batman, corrupted by his thirst for blood, murders all of Arkham's prisoners - including Amygdala, Victor Zsasz and the Mad Hatter - drinking their blood and decapitating to prevent them coming back as vampires.

Characterization
A number of other states and cities have transferred dangerously insane supervillains to Arkham Asylum despite its rather discouraging reputation, either because they lack facilities of their own to hold them, or find it easier to dump their criminal problem on Gotham City. Patients transferred from outside Gotham have included the Psycho-Pirate, Doctor Destiny, Jason Woodrue, Doc Willard, the Dummy, Dancer, the Crumbler, and Mister Thornton. Nearly every member of Batman's Rogues Gallery has been incarcerated at Arkham under various circumstances. Stockbroker Warren White, better known as the Great White Shark, was initially sent to Arkham after evading a white-collar fraud conviction in the Gotham courts by pleading insanity. His time inside the asylum drives him truly insane, and White comes to manipulate the system from within as a ruthless underworld racketeer.

Arkham in its various incarnations has proved to be extremely porous; escapes, even from maximum security wards, are bizarrely frequent; administrative releases are often handled in a negligent manner (on at least one occasion, an obsessive-compulsive multiple murderer was signed out of Arkham into the care of an incontinent, alcoholic vagrant, on the grounds that he "looked like a responsible citizen"), and consequently suffer from high recidivism. Arkham escapees and legitimate releases alike nearly always go on to commit subsequent crimes that land them back in the asylum to safely plot their next caper rather than the city jails or Blackgate Penitentiary. The administration is usually portrayed as ineffectual and corrupt, with inmates sometimes managing to seize control of the facility and embarking on an orgy of murder, destruction, and mayhem unopposed. With few recurring exceptions, such as Aaron Cash, the security force is troubled by exaggerated levels of apathy and, according to Arkham Asylum: Madness, a crippling turnover rate. The asylum's medical staffing has proved even more questionable, given how unstable several resident psychiatrists have become, including Jeremiah Arkham, Harleen Quinzel (Harley Quinn), and, in some incarnations, Jonathan Crane and Hugo Strange. Although the asylum is rebuilt in larger and larger iterations, an inevitable trend towards overcrowding has led to a breakdown in patient segregation&mdash;for instance, housing nonviolent and relatively harmless offenders on the same block or even in the same cell with serial killers, as in Arkham Asylum: Living Hell&mdash;and compels the staff to simply focus on warehousing the inmates rather than rehabilitating them. The practice of employees trading contraband, and even release forms, to prisoners in exchange for sexual favors is rampant. (Black Orchid #2)

Patient neglect is pervasive, which undoubtedly plays a major role in the countless number of escape attempts; for instance, in Neil Gaiman's The Sandman #1-5, inmates are not even provided with clothing, and Doctor Destiny is left naked in an unheated cell. Although the policy has fluctuated, Jeremiah Arkham initially never issued uniforms to supervillains admitted to his care in costume, preferring they remain so clothed so as to better shed light on their various disorders. This minimal supervision has allowed prisoners to smuggle in contraband, such as the Scarecrow did with a vial of fear toxin. (Batman: The Dark Knight #15) Arkham seems to favor prolonged solitary confinement as the preferred discipline for problem inmates; in Black Orchid Poison Ivy reports being held in solitary for three weeks on end, while Scarecrow is sentenced to three months in solitary at the conclusion of Arkham Asylum: Living Hell.

As Arkham does not seem to effectively treat its charges, a sentiment echoed often by police commissioner James Gordon, and it likewise cannot keep them detained, it remains under constant surveillance by an ever-vigilant Dark Knight and the GCPD.

Physical
"Arkham Asylum is generally portrayed, on the exterior, as a caricature of an insane asylum: a gigantic, gated Victorian home on a dark and stormy night. The image of the run-down, dreary building contrasts nicely with the individuals caged within, making Arkham a memorable location in nearly every comic in which it is featured. Arkham Asylum sometimes contains modern or futuristic technology, but every version includes some level of decay and entropy, resulting in a place constantly on the edge of disaster."

- Arkham being described in the critically acclaimed Icons of the American Comic Book, Volume One.

Arkham Asylum was associated with a rather unique visual motif for nearly a decade after its introduction, usually appearing as a sprawling Victorian campus with old stone walls and a number of dilapidated wings. Like the Arkham Sanitarium of Lovecratian fiction, it was based on Danvers State Hospital and several other nineteenth century lunatic asylums which adopted a similar architectural style. When Jeremiah Arkham's tenure as director commenced, work crews dismantled the old Victorian-era stonework, replacing it with a series of concentric labyrinthine corridors. The disorienting and mazelike atmosphere to Arkham's interior is intentional, engineered to confuse the inmates so even if they escaped their cells, they would find it difficult maintaining a sense of direction and escaping. CCTV cameras were now installed in every room and at periodic intervals in every corridor. Exterior windows were now fitted with heat and motion detectors, while magnetic foil insulation in the walls helped jam suspicious signal reception in the cell blocks.

Arkham Asylum reverted to its roots as an imposing manor when Jeremiah relocated operations to Mercey Island following the asylum's destruction by Bane. The Mercey Mansion was portrayed as possessing a particularly dark and gothic exterior which included pointed arches, octagonal towers, flying buttresses, vaulted ceilings, and decorative spires. It was an extremely tall, multi-storey structure, sweeping upwards to emphasize its loftiness and grandeur.

Treatment
Arkham Asylum has reportedly employed both psychiatrists and clinical psychologists; the latter are responsible for conducting most patient interviews and prescribing medication. As the most immediate concern for Arkham's administration is reducing the aggressiveness of high risk patients, prescriptions are often doled out for dopamine inhibitors such as Thorazine. Other common medications used by Arkham staff include Haloperidol (Haldol) and Fluoxetine (Prozac). (Robin, Volume Four #23) As most incarcerated supervillains such as the Joker rarely display the common side effects of these drugs, it has been theorized that the asylum's orderlies are failing to make certain they are properly administered, or pilfering the real medication and substituting cheaper, alternative pharmaceuticals which are less sedating, have lower rates of relapse, and result in subtler side effects.

Interviews are held periodically by Arkham's therapists for evaluation purposes; in the event of dealing with high-profile cases, sometimes an entire team of doctors may be present. (Detective Comics Volume Two #17) Patients are encouraged to discuss their lives, thoughts, and desires. The psychiatrists do not adhere to any set therapeutic model, so the results of the interviews may vary; for example, in Arkham Asylum: A Serious House on Serious Earth Dr. Ruth Adams favors word association&mdash;asking the interviewee to respond with the first word that comes to mind when offered an item from a word list. These sessions usually occur in specialized evaluation rooms overseen by unarmed orderlies prepared to physically restrain the patient as needed. If additional force is called for, each room is also fitted with a "panic button" that summons a crash team of armed security officers held on perpetual standby. A member of the team carries a video camera to document the incident from the guards' perspective and guarantee no excessive force is exerted off the record. (All-Star Western Volume Three #22)

Jeremiah Arkham's regime is a known proponent of electroconvulsive therapy. It is probable that the employment of shock treatment as punishment may be used in an unethical manner to deter antisocial conduct among the inmate population. Jeremiah once forced a "difficult case" to undergo ECT after he was observed smuggling contraband to the Joker, without providing a medical pretext or taking the patient's specific diagnosis into consideration. (Batman Villains Secret Files and Origins #1)

Inmates
Originally, Arkham Asylum was used only to house genuinely insane characters - the Joker and Two-Face were patients from its very first appearance - but over the course of the 1980s a trend was established of having the majority of Batman's supervillain opponents end up at Arkham, whether or not they were actually insane. This is likely because of some of the facility's high-tech features that make it more efficient to hold a villain such as Clayface there than in a prison. Nearly all of Batman's enemies have spent some time in Arkham.

Other DC Universe publications that feature Arkham Asylum and its patients include Alan Moore's Swamp Thing (wherein Jason Woodrue—The Floronic Man—is detained) and The Sandman by Neil Gaiman, wherein John Dee (Doctor Destiny) escapes to wreak havoc on both the 'real' and 'dream' worlds.

Arkham has also been featured in varying capacities in a number of high profile DC miniseries events, such as Identity Crisis, Day of Vengeance, Countdown, and Crisis on Infinite Earths among others.

In other media
Arkham has appeared beyond the pages of the comics in numerous guises and designs. Its appearances include:

Batman Forever
Arkham was seen at the end of the film, and designed as a tall, spiraling castle-like structure, with narrow hallways lined with brightly-lit glass bricks. The Riddler was incarcerated in a large padded cell. The psychologist seen was named Dr. Burton, a reference to Tim Burton, who directed 1989's Batman film and Batman Returns. There was a more in-depth sequence involving Two-Face escaping from Arkham at the beginning of the film, but it was cut.

Batman Forever (video game): The video game adaptation of the film features Arkham as its first stage. While the film shows Arkham as being in a remote forested area, the backgrounds in the game seem to place it on the waterfront, directly across the bay from Gotham.

Batman & Robin
Arkham appeared a number of times in this film. It first appeared when Mr. Freeze was taken there midway through the film, after getting defeated by Batman. Poison Ivy helps him escape by kissing his guards, killing them, and Bane helped by bringing Freeze's suit so he could live outside of the cold wing. They escape Arkham when Mr Freeze put some ice in a sink that leads to a water pipe on the wall, it created so much pressure the wall exploded, and to escape from the guards cutting into the steel doors, Mr Freeze, Poison Ivy, and Bane jump off into the ravine below, landing in a river. It also appears at the end of the movie when both Mr Freeze and Poison Ivy were shown as cellmates.

Batman Begins
Arkham played a much larger role than a simple jail in this film, with Jonathan Crane (also known as the Scarecrow) being either the administrator or at least a high ranking doctor at the Asylum, and using it to conduct cruel experiments with his fear gas, using his own patients as guinea pigs. He also used the pipes under the Asylum to empty his toxin into the Gotham water supply. One notable change in this version of Arkham from the comics was the location; while still on an island separate from the rest of the city (by 9 large drawbridges), in Batman Begins, it is located in the slum region known as The Narrows, as opposed to the remote forests that surround it in the comics. By the end of the film, it is implied that the Narrows has been rendered uninhabitable.

Batman: The Animated Series
Arkham has appeared frequently in the series. It is depicted as generally dark and gloomy, and the cells are similar to those in the comics, being primarily closed via glass doors. Much of the rest of the asylum resembles a prison more than a mental hospital, however; in one episode, it is explained that all criminals apprehended by the Batman are sent to Arkham rather than jail (although it is shown that The Penguin goes to Stonegate, a regular jail). In the series, neither Jeremiah or Amadeus Arkham are shown or mentioned, but the episode "Dreams In Darkness" features a character who is obviously modeled on Jeremiah, but toned down to have a more compassionate persona.

Justice League
Justice League featured Arkham in a brief cameo during A Better World: Part 2 in an alternate dimension where a Fascist League has taken over the world and dispatches villains via execution or lobotomy. The asylum is run by a lobotomized version of The Joker and is protected by robotic copies of Superman. The entire patient population is lobotomized by the alternate Superman's heat vision. (If you watch closely, you can see that the Ventriloquist has not been lobotomized by Superman's heat vision, but his doll Scarface has.) It is noted that Joker, Two-Face and Poison Ivy are used in both Batman: The Animated Series and Justice League as the key patients of the Asylum.

Batman Beyond: Return of the Joker
This direct-to-video animated film had the final battle between the original Batman and The Joker taking place at an abandoned Arkham. It is also the same spot where Robin (as a brainwashed, junior version of The Joker) killed Joker. A deleted scene (featured on both versions of the DVD as a special feature) has Bruce Wayne touring the abandoned Arkham, where Terry McGinnis, Wayne's successor as The Dark Knight, follows and sees Joker's corpse hanging (it was implied that the new Joker placed it up there fairly recently to intimidate Bruce Wayne, or anyone investigating it, since it was bound by ropes, which the Joker's recent corpse wasn't, and more importantly, his corpse now bears the words "I know" on it.).

The Batman
See: Arkham Asylum (The Batman) Like the original Arkham, several major villains end up in this institution, such as The Joker, The Penguin, The Riddler, Mr. Freeze, Ventriloquist, Hugo Strange and Clayface. Firefly goes to a regular prison. The staff is far more heavily armored than in its previous incarnation, wearing heavy trenchcoats and gloves, which is, in spite of itself, no deterrent for the patients to easily escape. Much like in the Batman Forever tie-in game and Batman Begins, it's presented as being inside Gotham, though here it's presented as occupying a small island on a river, with a bridge connecting it to the city.

Batman: The Brave and the Bold
In the episode "Mayhem of the Music Meister" Arkham Asylum is featured. The prisoners are Joker, Mr. Freeze, Mad Hatter, Top, Psyco Pirate, Tweedledee, Tweedledum, Two-Face, Scarecrow, Crazy Quilt, Doctor Polaris, Calendar Man, and King Tut. Batman also mentions in later episodes that other villains such as Black Mask and Hellgrammite are also prisoners there. In the episode "Joker the Vile and the Villainess" Joker is seen being transported to Arkham.

Batman: Gotham Knight
Expanding on Jim Gordon's line "The Narrows is lost" from Batman Begins, the Crossfire segment of Batman: Gotham Knight reveals that the inhabitants of The Narrows were repurposed, and the entire island (renamed Arkham Island) became asylum grounds. The asylum itself was transformed into a high-security fortress, with checkpoints and sniper towers augmenting the natural barrier of the island. This depiction was later utilized for Batman: Arkham Asylum.

Batman Forever
Arkham Asylum appears as the first level in the game after Two-Face's escape.

Lego Batman: The Videogame
There was an Arkham Asylum Lego set featuring the Scarecrow, Nightwing, Poison Ivy, and the Riddler available at Toys "R" Us during late summer 2006.

The videogame features Arkham Asylum as the villains' hub. It includes an experiment room, and docking bay for vehicles owned by The Joker, The Penguin, and Two-Face.

Batman: Arkham Asylum
Main article: Arkham Asylum (Batman: Arkham Asylum)

Arkham Asylum is the primary focus of the 2009 video game Batman: Arkham Asylum, which takes place during a riot orchestrated by the Joker. The facility is depicted a sprawling, multi-faceted campus with both new and old structures, including the iconic Victorian mansion of the comics, a factory re-purposed as an intensive care unit, and a vast subterranean network. This version of Arkham has also made cameo appearances in Batman: Arkham City, Batman: Arkham Origins, Batman: Arkham Knight, and Injustice: Gods Among Us.
