"If there’s one thing I learned by watching you - VIOLENCE SOLVES A LOT OF PROBLEMS!"
―Joker as a vigilante[src]
"I’m the villain of your dreams; the shadow within your shadow, the tumor lurking in your soul."
―Joker as a villain[src]

The Joker was a supporting character turned main antagonist in Telltale Games' Batman series. A mysterious patient at Arkham Asylum known as "John Doe", Joker became an ally to Bruce Wayne while he was incarcerated at the asylum. After he was discharged from the asylum, Joker went on to associate with a group of criminals called The Pact, whom he wished Bruce to get involved with. After the group disbanded, the actions of Bruce/Batman affected the Joker, and turned him into either a vigilante with a perverted sense of justice or one of the greatest threats Gotham City ever saw.

Biography

Nobody truly had an identity for the Joker, with the name "John Doe" that was given to him by the asylum staff. It seemed that John was also unaware of his past and didn't remember his life prior to Arkham, how he got there or even his own name. It seemed that no one even remembered the day that John arrived and there was no record of him ever being committed. Other inmates were scared of John, particularly Victor Zsasz, who found him unpredictable. However, to staff members, particularly doctors Joan Leland and Harleen Quinzel, John seemed to recover and was one of the more cooperative of the inmates.

While at Arkham, John became obsessed with Bruce Wayne and his activities in the public's eyes. He also began to admire Batman and his war against crime, particular criminals like Carmine Falcone. John kept a scrapbook of information and became determined to learn everything about Bruce. It's possible that John deduced that Bruce and Batman were one in the same, but it was left uncertain at that moment.

Season One

Guardian of Gotham

When John met Bruce in person, he found him being attacked by two inmates who claimed to be victims of his father, Thomas Wayne. After he came to Bruce's defense, John brutally assaulted them and offered help to Bruce. After Dr. Leland arrived, John tried to vouch that he had helped Bruce and that he had attacked the other inmates in defense. Bruce either went along with or denied the claims. After he was formerly introduced, John, Bruce, and Leland left the cell and showed him the way to the Lobby.

As they walked through the Asylum, John conversed with Leland, though he kept his eye on Bruce, and saved him from a cannibal who complained about "not being able to taste." John also banged violently on another inmate's door after he tried to use the phone, something that Leland noticed. After they arrived in the Lobby, John bullied "Sane Lewis" out of his seat and left to get the remote from Leland. Before he left, John gave Bruce a key and asked him to use it.

When he returned, John turned over the TV to the Gotham City News Channel, where he witnessed Harvey Dent announcing his imprisonment of Bruce to Arkham and laughed at the Mayor's ramblings about his war with Lady Arkham. When a report about Vicki Vale's disappearance appeared, John also revealed his knowledge that she was Lady Arkham's civilian identity, a piece of information that he suspected Bruce also knew. When Bruce confirmed his mutual knowledge, John offered to help set him free, noticed a "darker side" to him as he had attacked Oswald Cobblepot, and possibly realized who he was.

After he knew that Bruce would go after Vicki if he was released from the Asylum, John revealed Vale's identity as the current generation of the Arkham Family: Victoria Arkham. John also revealed her past, including her family's murder and the motivation for her crusade against Bruce. John offered to set Bruce free, but required a favor if he did so. Regardless of whether Bruce agreed to it, John went through with his plan to get Bruce released.

After he walked up to Zsasz, who played chess with another inmate, John asked him what would happen if a tally mark was made before a kill. With Zsasz unable to respond, John cut the serial killer's face with a knife, which caused him to lash out into his old ways. After John offered him a knife, John hoped that Zsasz's psychotic attack might distract the orderlies long enough for Bruce to get the phone and call to be released. Depending on what Bruce chose to do, the following possibilities happened:

If Bruce puts himself in front of Victor and tries to stop the fighting, John is surprised by his decision and watches as Bruce tries to subdue him. Following this, he is returned to his cell, where he catches Bruce leaving with with his butler. As he passes him, John calls out to "ask the Vales" as he is taken away.

If Bruce chooses to use the riot as a distraction to use the phone and continue with John's plan, John watches the fight unfold. After Bruce calls either Lt. Gordon or his lawyers to release him, John tells to "ask the Vales". As Bruce is taken away by Leland and an orderly, he tells Bruce that the two will see each other soon. John later sees Bruce as he leaves the asylum with his butler, Alfred. As he walks by, John reminds him of their deal.

City of Light

John was among the inmates who were set free during the Children of Arkham's attempted break out. However, unlike the other inmates, John simply watched the chaos unfold and seemed to enjoy every second of it. After he witnessed Batman defeat Zsasz, John clapped maniacally and told him how he "admired [his] work," which John possibly pretended that they had only just met. When the GCPD stormed the Lunchroom, John remained calm as an officer came in and arrested him.

In the following week, the staff at Arkham deemed John sane, decided to discharge him, and believed that he could return to society. It was possible that John had organized the attack in the event that announced James Gordon's promotion to Commissioner, though it remained unconfirmed. Regardless of his guilt, John watched the event at the Stacked Deck, during which, he witnessed either Bruce or Batman subdue the assassin. Entertained by the events, John either promised to see Bruce again or to top the attack, which depended on whether Bruce or Batman was present.

Season Two: The Enemy Within

The Enigma

During his year of freedom, John claimed to have found it hard to readjust to society. However, he also became acquainted with some of the world's most dangerous criminals and formed a group known as the Pact. Due to those connections, John became one of the most wanted people in the world for The Agency and its Director, Amanda Waller. After an attack on Wayne Enterprises, which was orchestrated by the Pact's leader, the Riddler, John decided to invoke the favor that he asked from Bruce, though the reasons remained unknown.

After he arrived at the funeral for Lucius Fox, a friend of Bruce who died from Riddler's attack, John talked with Lucius' daughter, Tiffany Fox and made a number of inappropriate comments and jokes until Bruce pulled him aside. John then gave Bruce a card that he bought and the two took their places in the pews as the sermon began. During that, John asked Bruce to meet the Pact for him and join the group as the favor that he asked for back at Arkham. When John mentioned Riddler, Bruce began to ask information about him, which lead to John giving him information about his operations in the East End of Gotham. As the funeral finished, John decided to leave and hoped to see Bruce again. Bruce had the opportunity to attach a tracking device to John, which John seemingly did not notice.

Later, John managed to learn about Riddler's safehouse in the East End and sent Bruce information about it. John also recommended talking to Rumi Mori, who was on Riddler's Kill List after Mori refused to sell one of his biotech companies. After he sent Bruce the information, John cut off the conversation to take care of other matters. It was unknown whether John was involved with one of the Pact's attacks on Gotham, though it's possible he may have assisted either Mr. Freeze or Harley Quinn.

The Pact

The following morning, John was either followed or contacted by Bruce, who decided to take up his offer to join the Pact. After Bruce found John at the Stacked Deck in the middle of therapy with another patron, Willy Deever, John finished the session before he went to talk with Bruce, during which John ordered him a drink. If Bruce placed the tracking device on him, John revealed his knowledge of it and expressed his annoyance, but seemingly forgave him for placing it on him.

When Bruce asked John about his involvement in the Riddler's death, John denied it and talked about Bruce joining him as a member of the Pact. John also admitted to having lied about Riddler's involvement with the group and promised not to have any more secrets between him and Bruce. John also offered a Pinky Swear, which Bruce had the opportunity to accept. While John contacted Harley to let her know, Willy tried to attack Bruce. If Bruce chose to subdue Willy, John recorded the incident. Regardless, John left and took Bruce to meet the others.

After he received a text from Harley that let him know that she was interested, John told Bruce about what was decided and told him about his feelings for her. John also decided to hot-wire a car, during which he asked for Bruce's assistance. After Harley arrived, John introduced the two and, at Harley's request, collected a slushy for her from a vendor. After he returned, they left in the car as the owner returned. When Harley flirted with Bruce, John showed signs of being uncomfortable and even snatched the slushy when she offered Bruce a drink. After they arrived outside Wayne Enterprises, John and Harley initially stayed behind in the car but followed Bruce into the building shortly afterward.

John and Harley followed Bruce to his office, knocked a security guard unconscious, and confronted Chairwoman Regina Zellerbach in the process. John also showed some signs of discomfort when Harley flirted with Bruce, and John suggested that they stayed focused on finding the Phalanx Key. When they arrived at the vault, John was disappointed to find no craters there and mistook the explosion to have taken there rather than in Lucius' Office. Whie Bruce recreated Lucius' thumbprint to access the vault, John looked around the lab and took notice of an EMP Generator. When Bruce finally got into the vault, John stayed behind with Harley, but later followed when he wondered what went on. Depending on whether Bruce lied to Tiffany at the funeral, the following happened:

If Bruce told Tiffany the truth about his involvement with Lucius' death, he will discover the two in conversation, with Bruce trying to get Tiffany to hand over the Phalanx Key. Bruce asks him to keep quiet, something he agrees to do but comments on hating to lie to Harley. Depending on whether he is successful or not, he will either take the key to Harley after Bruce is able to get Tiffany to hand it over or is stunned with a electric gun as she tries to escape. If the latter plays out, he will find the key on the floor and hand it over to Harley. As they leave, Harley asks him to bring the EMP generator with them, having decided to use it for their next attack.

If Bruce lied to Tiffany, John will be stunned with a taser as he enters the vault. He is also present whilst Harley threatens Tiffany and forces Bruce to pledge allegiance to the Pact for her safety. After Bruce either accepts or denies, he finds the Phalanx Key on the floor and gives it to Harley. As they leave, Harley asks him to bring the EMP generator, having decided to use it for their next attack.

After he and Harley returned, they and the rest of the Pact prepared to retrieve Riddler's body from the Agency. After they decided to bring him into the group, John contacted Bruce and told him to meet with the group. After Bruce was brought to Old Five Points, John watched as Bane and Harley argued whether to bring Bruce into the group. After he believed that Bane would kill Bruce, John activated the EMP Generator "accidentally" so he could prove his worth to the group.

When Harley tasked Bruce with getting the approval of Bane and Freeze, Bruce talked to John to get advice. Though he had no idea how to get Freeze's approval, John gave Bruce a bottle of beer so he could at least talk to Bane. When the group voted on whether to grant Bruce membership, John voted for him, regardless of his actions. If Bruce was unable to convince Bane and Freeze, that lead to a tie, which then lead to him to join the group.

During the attack on the Agency, John remained within the escape vehicles as Bruce and the other members engaged the agents in combat. John helped load the package and watched as the chaos ensued. Depending on who Bruce chose to stop, the following happened:

If Bruce chooses to stop Harley, she will escape with the rest of the Pact whilst Bane is left to fight the Agency. Despite Freeze's worries that Bane will seek revenge, John and Harley seem unconcerned about this. He is also present when Bruce opens the Riddler's casket.

If Bruce chooses to stop Bane, John will watch in horror as Harley is left to battle the Agency. Despite his pleas to go back and rescue her from the Agency, Bane and Freeze refuse, believing it to be worthless to go back for her. Furious, he storms back to his Ha-Hacienda to mourn.

Fractured Mask

Depending on who Bruce chose to stop in the previous episode, the following happened to John:

If Bruce chose to stop Harley, John helps Harley retrieve the payment for Catwoman from her safe and gives it to her. He stands by as Bane and his men return from battling the Agency and the GCPD and as Harley takes control of the Pact.

If Bruce chose to stop Bane, John stays in his Ha-Hacienda to mourn Harley's "death" and doesn't come out to interact with Catwoman. When she returns, he appears to greet her and stands by as she takes control of the Pact.

When Harley gave Bruce the task of investigating Riddler's hideout to find information about an Agency black site, she suggested John to help him. After he changed into something more suitable, John, Bruce, and Catwoman left to investigate the Riddler's lair.

After their arrival, John and Catwoman left to investigate the outside for GCPD Officers while Bruce checked the back. After they returned, John attempted to break down the fence with a crowbar, only for Bruce to intervene and take over the task, in to avoid attracting attention. Whie Bruce investigated the scene, John and Catwoman remained outside and only entered when Bruce was confronted by Harvey Bullock on the scene. When John retrieved the crowbar to knock Bullock out, Bruce either allowed him to do so or dealt with Bullock himself. Regardless, the three entered Riddler's lair and began their investigation.

While Catwoman investigated the balcony, John and Bruce searched the lower area of the hideout and uncovered a trap that was left behind by Riddler. Bruce also interacted with John, during which John told him about his distrust for Catwoman and about some of his history. When Bruce was able to solve Riddler's trap, he and Catwoman insisted that John stay behind while they investigated the uncovered elevator. When Catwoman tried to escape with the Decrypter, John only watched as Bruce attempted to stop her and took photographs with his phone. After the battle, John heard Catwoman mention her intention to steal a laptop in Harley's possession and decided to confront Bruce about it, but somewhere else other than Riddler's lair.

After he took Bruce to Café Triste, John ordered them drinks, which included a frappe for himself, and confronted Bruce on telling Harley about the laptop. John pondered telling her to improve her opinion of him but ultimately decided against it. After he witnessed some flirting between Bruce and Catwoman, John asked Bruce for some advice to help Harley notice him. Depending on the advice that Bruce gave, the following happened:

If Bruce advices John act like himself whilst trying to seduce Harley, he mentions that he feels unsure about doing so, as he hasn't found his "true self" yet. After taking some advice from Bruce, John asks that they role play some scenarios between him and Harley to improve his confidence. Afterwards, when Bruce decides to leave to "attend to business", John agrees to help him retrieve Harley's laptop and pays for the drinks. As he pays for the drinks, he seemingly fails to notice Bruce leave.

If Bruce advices John tries to manipulate her, he seems a bit unsure about doing so and asks for advice from Bruce. After learning some basic methods of finding out what can be done to get her to notice him, John decides to learn more about Bruce. Using napkins and some of Bruce's coffee, he creates Rorschach tests and asks him to answer. When Bruce decides to leave to "attend to business", John allows him to leave and offers to pay for the drinks. Depending on how Bruce answered, he will either says he'll think about helping him steal the laptop or decided not to go through with it. As he pays for the drinks, he seemingly fails to notice Bruce leave.

After the "disappearing act," John, noticed the Batsignal shining and realized that Bruce was Batman or finally had proof that they were the same person. After he decided to help him, John followed Batman to the rooftop of GCPD Headquarters and got Batman's attention by making shadow puppets with the Batsignal. After he introduced himself for what seemed to be the first time, John offered to help Batman arrest the Pact and retrieve Harley's laptop. However, John promised only to do so if she was left alone. John and Batman arranged to meet up behind the Stacked Deck if he was successful, which John agreed to do. After that, John took a selfie with his phone and showed it to Batman, with Batman either allowing him to keep it or destroying the phone. If the latter was chosen, John was shocked at that action and expressed his disappointment for losing it.

When Bruce returned to Old Five Points, John talked to him and advised that they used the opportunity to steal the laptop. When Harley came over to check on them, John tried to offer to help her search for the Pact's mole, only to be turned down and dismissed. While Harley and Bruce talked, John slipped into her office in order to retrieve the laptop for Batman. Depending on whether Batman told Catwoman about Gordon's ambush, John either didn't find it (if Catwoman was informed) or was able to steal it (if she wasn't told).

If the latter played out, John met with Batman and gave him the laptop. While John commented about feeling conflicted about stealing from Harley, he was pleased for having helped Batman and asked for a lesson in throwing a Batarang. If Batman agreed to do so, John received a demonstration on how to do it and was given the opportunity to throw one, unsuccessfully. After practice concluded, John asked to keep the Batarang that he practiced with, something which Batman agreed to. As Batman left, John promised him to stay out of trouble and help him, whenever he needed it.

When Harley discovered that the laptop was missing, John assisted her in investigating for the culprits. During the final preparations, John was given Riddler's position as "tech guy." If Harley did not found out about Tiffany or Project LOTUS, John also told her about those. After John learned that Harley had narrowed it down to Bruce and Catwoman, he begged her to let him interrogate Bruce and received some advice on what to do with her. When John finally interrogated Bruce, he worried about what they were going to do and suggested that they pin the blame on Catwoman. When Harley returned, John, who claimed to have finished, told Bruce to tell her who the mole was:

If Bruce blames Catwoman, John is pleased that he followed his advice and receives praise and affection from Harley for getting the information out of him. He also witnesses the rest of the Pact's attempt to kill her with one of Freeze's devices, but is otherwise not involved. After placing her in one of Riddler's death traps as a temporary cell, he, Bruce and the rest of the gang leave to raid the black-site.

If Bruce outs himself as the traitor, John is shocked at his decision, though also receives praise and affection from Harley for getting the information out of him. As he watches the others attempt to kill Bruce with one of Freeze's cryogenic chambers, he asks for them to spare him, only to be turn away. After they activate the chamber, he is forced to leave Bruce whilst he and the rest of the Pact raid the black-site.

What Ails You

Depending on who was given up as the mole, the following happened:

If Bruce chose to follow John's advice and blame Catwoman for the theft, he mostly stands by to observe whilst Bruce and the others battle employees of both the Bohdi Spa and SANCTUS. During the raid, he also takes a picture of the group on his phone to mark the occasion. John also catch Bruce communicating with Amanda Waller, but seems to remain oblivious to it, dismissing the action as him talking to himself. Knowing the Pact have come together to get their hands on the virus, John shares with Bruce his belief that they will disband once they get their hands on it.

When asked to install one of Riddler's drives, John supposed misunderstanding causes his position to be given to Bruce. He was amazed at Bruce's actions during the battle, including drawing a turret's fire to allow Harley to destroy it. When Bruce gets separated, John and the rest of the Pact are forced to disable another turret and, as he tries to destroy Project LOTUS, watches as Bane tries to stop him from doing so. When Bane comes close to killing Bruce, John interferes and attacking him, allowing the billionaire to subdue him. When Harley betrays the group, John is shocked by her leaving them behind and flees the scene as the Agency arrives.

If Bruce chose to blow his cover, it is unknown how involved he was in the raid on the lab. After making it into the lab, John's impatience leads to him continually pestering Freeze to hurry up with the extraction, which is looked down upon by Bane. When Batman arrives on the scene with Catwoman, John initially suggests a peaceful method, but does not get involved as they battle the rest of the Pact. However, whilst Bane has Batman trapped, John prevents Freeze from attempting to kill the vigilante, telling him to fight his own hero. When Harley betrays the Pact and escapes with the virus, John is shocked at this betrayal, but manages to escape as the Agency arrives.

After the raid, John fled back to Old Five Points in order to hide from the Agency, only to find their operatives already there. After he hid in a place that they could not find him, John watched as they stole Riddler's blood, from both his corpse and the samples that were collected by Freeze. Eventually, John was discovered by Harley, who returned to retrieve the samples and synthesize a usable version of LOTUS. After he told her what he'd seen, Harley rejected John and gave him a black eye before she fled. With his feelings truly broken, John broke into Harley's Office and drank himself into unconsciousness.

Eventually, John was discovered by Bruce and Special Agent Iman Avesta, who returned in search of Quinn. After he was woken up, John drunkenly introduced himself to Avesta and ranted about his perceived one-sided friendship with Bruce. John blamed Bruce for the advice that he had given him to win over Harley and showed his frustrations about how the Pact had been disbanded. As Bruce tried to get more answers from him, John drew a gun on him and Avesta and was talked into dropping it.

As John attempted to leave, Avesta blocked his entrance while Bruce talked him into telling them about what had happened. Though reluctant to help them find Harley, John was talked into doing so but insisted on doing so alone. Regardless of whether Bruce chose to let John go alone or join him, John left to find Harley by himself. If Bruce insisted that he joined John, John held him and Avesta at gunpoint before he fled and ensured that they did not follow him.

John eventually tracked Harley down to the defunct Bonus Brothers Carnival, where she had stored one of the GCPD's armored vehicles after the attack on the Agency convoy. After he informed Bruce, John investigated the Funhouse where he and Harley had set up a lair and discovered multiple agents there. John murdered the agents, though he claimed it was only in self-defense. Eventually, John was discovered talking to the agent's corpses by Bruce, who came after he was given the lead to follow.

After he was discovered, John claimed that he was attacked by the Agency and, succumbing to something dark building up inside him, had bludgeoned them to death with the nearest object that he could grab. However, Bruce found multiple holes in the story, including a gunshot wound to an agent's back. Depending on dialogue chosen, John and Bruce's "friendship" either improved or decreased. During the conversation, John revealed that he knew that Bruce was actually Batman and deduced it some time ago. If Bruce didn't acknowledge that to be true, John gave him evidence to support his claim, along with actions that he had taken throughout his time in the Pact. After he revealed that Harley had fled to the Gotham Bridge, John asked Bruce to help capture her before she did anything too drastic. John also asked Bruce whether he believed his story and promised to help if he did. Depending on whether Bruce believed John, the following possibilities happened:

If Bruce chooses to believe John, he joins Bruce to capture Harley on the Gotham Bridge. Worried that the Agency may kill Harley, he asks Bruce to get involved and stop them from doing so. When Waller shows surprise on his appearance, he simply waves at her as Bruce talks to her. With Waller running out of options, she allows them to try and talk her out of destroying the bridge. As he watches as Bruce struggles to get Harley to stand down, John goes up and tries to talk to her himself. If Bruce lets him take over negotiations, he promises to get her to stand down. As John communicates with her. the two seem to make flirty gestures towards each other, leading Waller to suspect that he will not be successful and orders her teams to go in. Depending on the choices made, the follow will happen.

If Bruce puts faith in John and is able to prevent Waller from interfering, John is able to subdue her and hands her over to the Agency. As Harley asks him why he had betrayed her, he comments that he has been shown how to be good. When Waller asks him to hand over the virus, John refuses to, believing that it should be destroyed. When she tries to kill him, John realizes she is as bad as the Pact and calls her corrupt. He then steals a smoke grenade from an agent, which he sets off, makes an attempt on Waller's life and detonates Harley's bombs. Climbing on the bridge's railing, John promises to bring the Agency to justice before jumping off the side.

If Bruce chooses not to let John negotiate or begins to suspect he's up to something, he takes the trigger from Harley's hand and demands that they stand down. Chastising Bruce for not trusting him, he calls the billionaire dangerous and berates him for trusting Waller. As he sees Harley being dragged away, John blames Bruce for what has happened and detonates the bombs. Standing on the side of the bridge, he embraces his madness and is praised by Harley for what he has done. He then kisses her and jumps off the bridge, the two disappearing into the night.

If Bruce chooses not to believe him, John admits his disappointment and, believing he should be at Harley's side, tries to escape. As Bruce chases after him, he blocks his path with some mannequins and escapes. John then flees to another location, where he collects one of the stolen vehicles, and drives to the bridge to save Harley.

Arriving in the midst of a failed negotiation between Batman and Quinn, John drives his truck into the bridge, indirectly releases Harley's bombs onto the entire bridge and causes Batman to miss an attempt to steal either the virus or the detonator. He then makes his presence known to everyone and admits his loyalty to Harley. Taking the detonator from her, he berates Batman for not helping him and calls what he stands for "a joke". Venting his frustrations, John takes control and sets off the bombs to destroy the bridge. As he watches the carnage ensure, John tells Batman that he could have prevented this destruction and how he has created him. As Harley praises him, John kisses her and jumps off the bridge, disappearing into the night.

Same Stitch

After the events on the bridge, John decided to discard the name that he was given at Arkham and adopted a new identity: Joker. The Agency also began manhunts to find Joker and capture either Harley or Batman. Depending on the choices made in the previous episode, the Joker became either a vigilante or a villain. Depending on what happened, the following possibilities will happened:

If Bruce believed that he killed the agents in self defense and trusted him enough to help capture Harley Quinn, Joker becomes obsessed with helping Batman bring criminals to justice and begins assembling his own crew to help him. With Stacked Deck patrons Willy Deever, Frank Dumfree and Lauren deciding to help him, he begins creating his own gadgets and weapons to help him and creates a new costume based around clowns and happiness. Together, the group set up base in the disused Ace Chemical Processing Plant. After several weeks, Joker sends his followers to Riddler's old hideout to attract the Agency's attention.

When Batman arrives on the scene, the Joker attacks the agents as they subdue Batman with their stun pistols. Working together, they defeat the group, despite being severely out numbered. As Joker introduces Batman to his helpers, one of the agents, Roger Harrison, calls the Agency to send an asset in to capture them. As the Agency drops of the package, revealed to be an enhanced Bane, Joker tells his followers to escape whilst he and Batman deal with the criminal.

With Bane's venom injections now lasting longer and using a tubing system as opposed to the injections, Joker and Batman find it hard to defeat the bohemeth. Joker is also shocked as Willy dies trying to stop Harrison, if Batman doesn't react in time or decides to save the Agency operative instead. At Batman's suggestion, Joker either rams Bane in his Jokermobile or drops a smokestack chimney on him. As he confronts Bane, he learns that Waller has incorrectly implicated him for Riddler's death, causing him to lash out in anger. After being called off by Batman, the two leave as more agents arrive.

Making their way to an alleyway, they are met by Alfred, who has come to help Bruce look after his injuries. Delighted to finally meet Bruce's guardian in person, John offers to help Bruce look after his injury, only to be declined. Whilst Bruce takes care of his injury using a medical kit, John converses with Alfred. After Bruce finishes, he listens to Amanda Waller's demands for both him and the LOTUS virus. Though he contemplates killing her with the virus, Joker ultimately is convinced to hand it over to Bruce to destroy it. Afterwards, he accompanies Bruce as he meets up with Iman Avesta to get blackmail on Waller. Whilst Batman meets the agent, Joker is told to stay hidden whilst he meets with her.

After watching Batman negotiate with Waller for her to leave and possibly hand him over for an additional demand, Joker, furious at his actions, intervenes and makes his presence known. Believing that he isn't willing to do what is necessary to protect Gotham, he attacks Waller and his former compatriots in the Pact, who have now become assets to the Agency. Fighting both his former friends and agents, Joker and Batman are quickly overwhelmed and surrounded. Believing there are no other options, Joker throws two bombs towards both the Agency and the Pact, hoping that they will force them back or kill them.

To his surprise, Batman chases after them, successfully throwing one of them to safety whilst he is injured trying to stop the other. Following this, Joker fights his way through the survivors and captures Waller, taking her hostage and fleeing. Though chased through Gotham, he manages to lose his pursuers and takes her to his hideout. Joker and his crew set up plans to force confessions out of Waller about the Agency's involvement in illegal or unethical activities, destroying both her and the organization's credit, and then execute her. With that, he plans to target other organizations, though it is currently not known which ones specifically.

During the midst of filming, Batman arrives to save her. Joyed that the vigilante has survived, Joker pleads with him to stand by and let Waller die or help him bring down the other criminals in Gotham, using his new and somewhat twisted brand of justice. Batman refuses, causing him to question his friendship and whether Bruce is actually using the Batman identity as a façade. As he attempts to execute Waller, Batman stops him. Sending his gang to fight him, Joker takes Waller to the higher levels of the facility, hoping to get her to confess to Riddler's murder.

When Batman arrives, having defeated his allies, Joker tries to get Waller to confess to Riddler's murder, believing that she had framed him in order to cover her own tracks. With her refusing, Joker threatens to drop her into one of the vats, only for Tiffany Fox to appear and confess to the murder. Though he initially disbelieves her, the evidence she presents causes him to realize she is telling the truth and he tries to kill her. When Batman steps in the way, Joker decides to attack him, only for him to be tackled over the railing by Waller. Before he falls into one of the vats, Batman catches him with his grappling gun, but Joker uses his own to reach one of the other walkways.

As he tries to escape, Waller's agents arrive to stop him. Losing faith in Batman and his war on crime, Joker attacks the agents, killing them, and embraces his new identity. With Batman standing in his way, Joker engages the vigilante in an fight, the two evenly matched with their skills and equipment. Managing to gain the upper hand, Joker moves back to try to kill Waller and Tiffany, only for Batman catch up and stop him. Chased to the control room of the plant, Joker realizes that he is destined to become a "villain" and continues to fight Batman, eventually ending with both of them severely injured.

Finally defeated, Joker tells Bruce how much he really wanted to be a hero and asked whether he actually considered him a friend. Regardless of what Bruce says, he falls unconscious and is later found by either the GCPD or the Agency. Whilst Batman is taken away for medical aid, Gordon organizes for Joker to be returned to Arkham Asylum. Left alone in his cell, he is left to contemplate his actions. If Bruce revealed to him that he considered him a friend, he visits Joker in his cell, much to the latter's joy. However, if he was told he was an enemy, he decides to become "enemies for life" with Batman.

If Bruce didn't believe John or trust him to arrest Harley Quinn, Joker and Harley put together their own criminal gang, which he plans revenge against Wayne. Setting up himself, Harley and their gang in the abandoned Ace Chemical Processing Plant, Joker helps Harley create more batches of Project LOTUS, planning to use it to attack the city. He also, with help from Willy, designs a new costume around clowns and creates new weapons and equipment to help him. Joker also captures Catwoman, deduces Tiffany Fox is responsible for Riddler's murder and sends Bruce a message, warning him about his plans.

Using a mole in Wayne Enterprises, Joker is able to falsify documents from Regina Zellerbach that are ordering weapons. Stealing a van, he tells his men to attract the GCPD's attention and, if they did, use an officer as a hostage, hoping to get Batman's attention. The men will eventually capture the detective he and Bruce encountered and, after restraining him, stuff a jack-in-the-box into his stomach. They then leave a weapons create behind, with the false order from Zellerbach.

After their informant tells them that Bruce Wayne had arrived to confront Zellerbach during a board meeting, Joker, Harley and their men attack and take them hostage. Using Willy to announce him, Joker makes his appearance, making the board aware of his relationship to Bruce and revealing to his new enemy how them had been replicating the virus. Whilst the gang put on gasmasks, forcing one of them onto Bruce, Joker releases the virus, killing the enter board. Whilst Harley makes a video giving a number of outrageous demands, Joker tells Bruce how he had decided to become his ultimate enemy and will not stop until either of them are dead. He then allows Harley to knock him out and spread the virus around the rest of Wayne Tower. During this, he leaves a rag, with clues to lead Bruce to one of the bombs at Divinity Church.

Whilst Batman deals with the bomb, Joker contacts Gordon, offering him the location of all of the bombs, in return for Batman. Gordon agrees and contacts Batman, asking the vigilante to come to Ace Chemicals. If Batman has stood beside Gordon for at least one of his actions, he tries to call the deal off, only for Joker to knock him out. When Batman arrives, Joker's men attack him and subdue him. When Joker arrives, he kills one of his men to prevent him from killing Gordon and gives him a map of all the locations of the bombs. As the former commissioner leaves to hand it over to the authorities, Joker shoots him in the legs and tells his men to move him to his car.

With Batman now at his mercy, Joker reveals how Gordon had been only the first of his allies he would "corrupt" and how he knows was betraying Harley, though admits that he enjoys her "the way she is". Going briefly into deep thought, he quickly broke out of it and told the vigilante how she may just activate the bombs if she is told about what had happened. After Batman referred to him as his given name, Joker electrocuted him into unconsciousness.

Taking him back to the Bonus Brothers Carnival, Joker removes the Batsuit, replacing it with a tuxedo, and handcuffed him to one of the attractions. During him time unconscious, Joker contacts Alfred, threatening Bruce's life if he refuses to come to the carnival, and captures Tiffany, locking her within the murder mystery room. Whilst Bruce recovers, Joker makes Selina choose between her freedom and Bruce's. Having timed her answer with Bruce's entry to the room, he reveals the choice and forces him to choose whether he would try to escape himself or trust Selina with their only chance of escape. Regardless, he would forces to work together, forcing them to crawl through a tunnel of glass. When Bruce and Selina arrive in the murder mystery room, he forces them to deduce who killed each person presented. After they solve the puzzle, he reveals a trapped Tiffany and that she was Riddler's murderer.

Afterwards, Joker and Harley present a "family meal" to the group, forcing them to play along by demonstrating Selina's shock collar. After tying them down to their chairs, Joker and Harley offers Bruce a piece of steak with a object in, which he can refuse. When Alfred arrived with scones, Joker forces Bruce to choose before hitting him with the tray. He also stabs him with a knife, later letting go after it either breaks or being head-butted by an angry Bruce. With everyone in the vicinity, Harley reveals a canister full of LOTUS, which she threatens to set off. However, Joker instead asks for them to play a game of "Never Have I Ever", forcing each other them to reveal their darkest secrets.

With Harley agreeing, Joker gives each of them rules, forcing Bruce to play along for his and his friends' lives. Forcing Alfred and Selina to reveal that they have lied or manipulated him, Joker also forces him to admit he's done the same to him. Whilst he tries to force Tiffany to admit to murder, he is distracted by her threats towards him and Harley. Trying to get Bruce to confess to "John Doe"'s murder, Joker fails to notice the billionaire cut his bonds with the knife he lost. When Harley tries to release LOTUS, Bruce turns her against him by revealing he gave the locations of the bombs to Gordon or his fixation with him. Regardless, he is able to distract her long enough to defuse the bomb and, using a Bat-Stunner hidden within one of Alfred's scones, stuns either Joker or Harley.

With Bruce and his friends free, Joker and Harley engage them in a fight, during which he briefly incapacitates Selina with her collar. However, Bruce is able to get the controls away from him, freeing Selina and making the fight even. Using his joke weapons and gadgets, Joker is almost able to defeat them, but is forced to flee after Bruce foils an attempt on Selina's life. Chased to and cornered at another area of the carnival, Joker tries to make Bruce admit that he needs him and engages him in a brutal fight. The billionaire ultimately defeats him and continually beats him, causing him to have a catatonic heart attack.

Realizing Joker is dying, Bruce uses a Bat-Stunner as a defibrillator, eventually reviving him. Surprised that he would actually save him, Joker tries to find out why Bruce had saved him, despite everything he's done. Regardless of the choice, he remembers the night they had shared together at Café Trisle, eventually asking Bruce whether he remembers any good things from their time together. Regardless of the answer, he stabs him with a knife he has, telling him to remember their experiences with the injury he's given him.

Joker is later captured by the GCPD or the Agency and transferred back to Arkham Asylum. Within his cell, he plays with a doll replica of Bruce. Depending on the choices made, Joker either plays with it, pretending the billionaire has visited him, or burns it, promising to see Batman again.

Personality

During his first meeting with Bruce at Arkham, Joker seemed to be very unpredictable. He seemed bored with the order that was imposed by the staff and enjoyed chaos when it occurred. He seemed to find both the Children of Arkham's actions and Harvey Dent's wavering sanity entertaining. Joker also seemed to enjoy harmless pranks, including giving a key that didn't unlock anything to Bruce, just to see whether he tried it. According to Leland, Joker also had issues with rejection, something that was confirmed if Bruce decided not to go through with their "favor."

While he was free, Joker seemed to find it hard to adjust to freedom and seemed drawn to chaos, which led to his involvement with the Pact and falling in love with Harley. Joker also seemed to have little confidence in himself. Despite putting on a show of obliviousness and incompetence, Joker was extremely intelligent, was aware of the actions around him, and even deduced that Bruce Wayne was Batman. It also seemed that Joker had a habit of giggling when he was nervous.

Up until his identity formation, Joker displayed a contrast between a cunning, capable individual and a desperate, vulnerable wallflower. He gave a "get well soon" card to Bruce at Lucius' Funeral, yet subsequently mentioned his association with Riddler in order to aid him in his search. With that, it was difficult for Bruce at times to discern whether his associate was genuinely reaching out to John or goading him. Even if John offered to retrieve Harley's laptop for Bruce following their communication exercise, he contrastingly proceeded to later offer Batman the same.

If Joker became a vigilante, he became overtly passionate for his crusade for justice and even exhibited frequent recklessness on multiple occasions. However, when Batman cornered him in the office, Joker softly confessed that this may have been a ruse in order to gain Batman's admiration. As a villain, Joker's personality became extremely sadist, he did not shy away from disturbing acts, and manipulated others to get what he wanted. Despite that, Joker seemed to still care about Bruce and could not commit himself to let Bruce die.

Regardless of Joker's fate, it was gradually revealed that John was always drawn to violence and chaos, whether it was for malicious purposes (as in the case of his villain scenario) or for misguided lust for justice (as in the case of the vigilante scenario). Depending on Bruce's choices, Joker could become the most deranged and evil of Batman's Rogues' Gallery or the most flawed with a true lust to do good.

Relationships

Bruce Wayne/Batman

Joker welcomed Bruce when he first arrived at Arkham Asylum and personally saved him from a group of patients who tried to attack him. Joker even willingly organized a distraction in order to give Bruce a chance of making a phone call, in return for a favor once he was released from Arkham. It was unknown how Joker found out that Bruce was Batman, but it was implied that he knew during their first meeting at Arkham (though it was later claimed that he deduced it after his "disappearing act"). Regardless, Joker seemed to admire Batman, especially when he got the chance to see him in action.

When Joker was released, he listed Bruce as an emergency contact. He made contact with Bruce a year later and hoped to have him join the Pact. When Joker discovered Bruce tracking down the Riddler, he also offered to give him information on how to find him, a promise which he kept. Bruce later joined the Pact, with Joker ecstatic that he could join, and he assisted in the process of his induction. Joker had a blank frame, which he was reserved for a photo of him and Batman. When Joker met Bruce as Batman, he offered to help him in the field, and offered to retrieve the laptop from Harley and help him take them down, but in return for her safety. If Joker was successful, he was able to bond with Batman and got closer to him.

Joker seemed to care about Bruce's well being and even suggested that they give up Catwoman as the mole in order to protect him. However, after the fall of the Pact, Joker blamed Bruce for causing the fall and began to doubt their friendship. After he killed a number of agents in claimed self-defense, Joker's friendship with Bruce became either better or worse and depended on whether Bruce trusted or believed him. If Bruce did, Joker vowed to bring the Agency to "justice" along with Batman. However, if Bruce didn't trust or believe him, Joker became heartbroken, swore to ruin Bruce's life, and was spurred on by Harley's support.

If Joker became a vigilante, the two worked together and fought off the Agency, though Joker's methods and willingness to kill and use of lethal force left him at odds with Batman. Despite that and deducing that he had actually been used by the Pact, Joker seemed to still admire Batman, and, should Bruce reveal that he considered him to be a friend, retained their friendship, and even visited him at Arkham. However, if Bruce revealed that he didn't, Joker swore and became his "enemy for life".

If Joker became a villain, he worked to break Bruce down and made him feel the sense of betrayal that he instilled in him. That included attacking Gotham with the LOTUS Virus and turning his allies against him. Despite that, Joker seemed to still care deeply for Bruce, kept his activities as Batman secret, and kept Harley from killing him. In the end, Joker asked Bruce if he enjoyed their time together and, depending on the answer, either maintained his obsession with Bruce or swore to kill him.

Selina Kyle/Catwoman

Upon first meeting Catwoman, Joker seemed to have a positive relationship with her and was willing to get to know or work with her. However, after he learned that she was an associate to Riddler, Joker became suspicious of her and kept an eye on her. When Catwoman and Bruce were narrowed down to the only possible moles, Joker was willing to put her in danger in order to protect Bruce. Regardless of what he became, Joker seemed to have had an antagonistic relationship with Catwoman and either fought with her on the rooftop of the GCPD or used her as part of his games against Bruce.

The Pact

Dr. Harleen Quinzel/Harley Quinn

Joker had known Harleen Quinzel from his time at Arkham, as she was one of his psychiatrists during his time there. When he joined the Pact, Joker served as Harley's right-hand man and helped her whenever she required something. Joker claimed that he had fallen in love with her, due to her violent actions and pensions to stir things up. In an attempt to try to impress her, Joker asked Bruce for advice and take on any action that she requested of him. After Harley betrayed the Pact and gave him a black eye when he tried to help her, Joker's feelings towards her seemed to be broken. If Bruce trusts him, Joker will even defuse a hostage situation that Harley arranged and renounced his love for her in favor of joining Bruce's side. Despite that, Joker seemed to still care for her and even regretted handing her over to the Agency.

However, if Bruce does not trust or believe Joker, he would help her and takes control of an escape from the confrontation. During that, they shared a kiss, which cemented Joker's love for Harley and his fall into chaos. Together, Joker and Harley would work together on a plan to release the LOTUS Virus throughout Gotham and get revenge on Bruce for betraying them both. Despite seemingly becoming an item, Joker will betray Harley by undermining their plan, by giving Gordon the bomb locations in exchange for Batman, and kept secrets from her, such as the vigilante's identity. After either his obsession with Bruce or his betrayal is revealed, Joker and Harley's relationship quickly breaks down and, during a fight between them, Bruce and Selina, Joker will leave Harley behind in an attempt to escape.

The Riddler

Joker's relationship with Riddler was very poor, due to Riddler's apparent rudeness around him. That included interrupting Joker while he told jokes or stole attention away from him. It also seemed that Riddler had negative feelings toward him also and called Joker a "white-faced prick." When Bruce questioned him about his involvement in his murder, Joker denied playing a part in Riddler's death. However, Joker seemed delighted after he learned of Riddler's death and even openly mocked him during the news flash.

Bane

It seemed that Joker and Bane, like Riddler, had a very poor relationship. However, Joker was willing to speak to Bane, though he had to provide Bane with beer if he wished to speak to him. If Harley was left behind to battle the Agency, Joker chastised Bane for doing so. However, if Bane was left behind by the Pact, Joker also seemed unconcerned about Bane and commented that he probably had a "brawl." When Bane attacked Bruce/Batman during the raid on SANCTUS, Joker betrayed Bane in order to save Bruce/Batman from harm. If Joker became a vigilante, he fought against Bane, though he seemed concerned with other's well being rather than a grudge against him. However, when Bane accused Jokerof murdering Riddler, Joker attacked him in anger and even went as far as attempted murder.

Dr. Victor Fries/Mr. Freeze

It's unknown what the precise relationship between Joker and Freeze was, but it's likely to be not as bad as it was with Riddler and Bane. However, after Joker "accidentally" activated the EMP Generator, which endangered Nora, Freeze threatened to kill him unless someone deactivated the device. Joker could also have been impatient with Freeze, which was shown when Freeze extracted the LOTUS Vials, and was willing to betray him in order to save Batman.

Amanda Waller

From the outset, Joker was distrustful of Amanda Waller, due to the Agency's actions and her ruthlessness. If Joker tried to help Bruce capture Harley on the Gotham Bridge, he initially tried to work with Waller if he helped deal with Harley's demands. However, if Joker successfully captured harley, Waller attempted to shoot him after he refused to hand over the LOTUS Virus. That action lead to Joker to realize that Waller was "corrupt" and he vowed to bring her to justice. With that, Joker became enraged at Waller's betrayal and attacked her before he escaped.

The vigilante path saw Joker continue to maim Waller's Agents, and confront her on the GCPD Rooftop for hunting him. Joker even blamed Waller for Riddler's death and believed that she accused him of the crime in order to cover her tracks. When Waller both mocked Joker's mission and dismissed his accusations, Joker made several attempts to kill her, though he eventually resorted to kidnapping. During his interrogation, Joker refused to believe Waller innocent of Riddler's murder and acted as Judge, Jury, and Executioner. When Batman tried to intervene, Joker began to believe that both Batman and Waller were similar.

The villain path saw Joker's animosity lie toward Bruce, but Joker conducted grisly murder toward Waller's transport crew who guarded Selina, and even listed one of his and Harley's demands as "Waller being shot out of a cannon by midnight".

Trivia

  • The character received critical acclaim and many critics noted how that was one of the first truly sympathetic portrayals of the Joker that ever came along and praised the player's ability to shape John's decisions, which affected what kind of a villain John became.
  • Prior to his "transformation," Joker was constantly referred to as "John Doe", a name that was given to male individuals whose names are unknown. After the transformation, he was referred to with both names. In the first season, the credits listed John as "Joker", while the second season's credits listed him as "John" until Same Stitch.
    • The name "John Doe" was also used by the main antagonist of the thriller, Se7en.
  • Although he was initially a supporting character, Joker served as the main antagonist of Same Stitch.
  • During the Vigilante Joker path, it was mentioned that the aliases that Joker considered included Birdman and Hawkman. The former was usually used in a name for characters in fiction, including several parodies of Batman, while the latter was a reference to the DC superhero of the same name.
  • Joker's standing with Batman in the second season was similar to Harvey Dent/Two-Face's in the first, as it was friendly but changed and depended on the choices that were made by the player.
  • Prior to the revelation of his knowledge, it was implied that Joker was aware of Bruce's dual identity during their first meeting in Guardian of Gotham. It was also worthy to know how Joker learned about Lady Arkham's true identity as Victoria Arkham and where she kept the Children of Arkham's drug cache. However, it was hard to take Joker at his word, so it remained unclear how he knew about those events.
  • Joker's house at Old Five Points was called the "Ha-Hacienda," a reference to his name for the various hideouts that he used in both comics and other media. In addition, the interior and death traps in his hideout in the Bonus Bros. Carnival were very reminiscent of his lair in the 1988 graphic novel, Batman: The Killing Joke.
  • Some of Joker's behavior suggested that he may have suffered from Borderline Personality Disorder (BPD), with him suffering from intense mood swings, bouts of violent anger when he felt frustrated or humiliated, paranoia, and hallucinations. Joker's obsession over his interpersonal relationships, an extreme fear of abandonment, and whipping himself up into hysteria out of the very idea that Bruce would be angry with him also seemed to imply that may have been what he suffered from.
  • In The Enemy Within, there was a role reversal in the traditional Joker/Harley Quinn relationship. While in most media, Joker was the dominant one and steered Harleen Quinzel toward becoming a criminal. The second season presented the polar opposite, with Harley the one in control and "John" being submissive, and, through her influence, steered toward his transformation into the Joker.
  • In both endings to City of Light, "John" was shown with red lips while he watched the assassin's failure on the news. However, those were absent in The Enemy Within until his "transformation" into the Joker in either What Ails You or Same Stitch.
  • Villain Joker's outfit was similar to the variations that were used by the iterations in both Tim Burton's Batman and The Dark Knight. The shaved eye-brow was possibly a reference to the version present in the DC Extend Universe.
  • It was unknown how Joker was legally kept at Arkham if the staff there had no record of him ever being committed or if he never gave his name to anyone.
  • Despite not being the one who killed Riddler, Tiffany's shadow at the end of The Enigma resembled Joker's character model.
  • It is very possible Joker was a victim of Thomas Wayne kept in Arkham.
