List of Gotham characters
Gotham is an American crime television series developed by Bruno Heller, based on characters appearing in and published by DC Comics in their Batman franchise, primarily those of James Gordon and Bruce Wayne. The series premiered in the United States on September 22, 2014 on Fox television network. The series stars Ben McKenzie as the young Gordon while Heller executive produces along with Danny Cannon, who also directed the pilot.
As originally conceived, the series would have served as a straightforward story of Gordon's early days on the Gotham City Police Department, but the idea evolved, not only to include Wayne's "transformation" into Batman, but also to explore the origin stories of several of his villains, such as Penguin, Riddler, Catwoman and several others.
The following is a list of characters who have appeared in the television series. In addition to directly adapted characters from DC Comics, many others are based on, inspired by and/or otherwise reference preexisting characters without sharing the exact same identities.

James "Jim" Gordon (portrayed by Ben McKenzie; season 1–5) is a war veteran and homicide detective at the Gotham City Police Department in its 1st Grade working to find the man who killed Bruce Wayne's parents and battling the corruption of Gotham City's Police Department. His father was Gotham City's District Attorney before his death in a car accident when Gordon was 13 years old.
Fox began to develop a TV series centered on James Gordon's early days as a police detective and the origin stories of various Batman villains in September 2013. McKenzie was cast as the lead character. When describing his character in an interview, McKenzie stated that Gordon "is a truly honest man. The last honest man in a city full of crooked people. He's not an anti-hero, he's a true hero – but he will have to compromise". McKenzie did not audition for the role. Heller, with whom he had worked before, wrote the role for McKenzie, who described the character as "an old-fashioned hero in an age of anti-heroes. A throwback. Jim's a lawman, that restricts him in some ways. But also means he can become powerful within the system and change things for the better". In the show, Gordon is assigned to investigate the murder of Thomas and Martha Wayne, with Bruce being the surviving witness. During the first season, he is assigned with a new partner, Harvey Bullock, serving also to police captain Sarah Essen. In addition to the Wayne's murder case, Gordon solves various cases in Gotham, some of them which are connected to the powerful mob figures, like Fish Mooney, Carmine Falcone and Sal Maroni. Jim also fights against a corruption in GCPD, like the police commissioner Gillian B. Loeb and Narcotics Officer Arnold Flass. To better fight against a criminals and a corrupt cops, Gordon gets the allies, such as police detectives Renee Montoya and Crispus Allen and a district attorney Harvey Dent. Gordon soon becomes reluctant ally to a criminal named Oswald Cobblepot, often calling him for the favor in some cases. He also meets a small street thief Selina Kyle, who reluctantly helps him regarding the Wayne murders. At one point when is assigned to Arkham Asylum, he meets physician Leslie Thompkins who works in female ward, later working as a medical examiner in GCPD. Gordon later falls in love with her; he was previously in relationship with Barbara Kean, but due to his police duty and her life put in danger by crime families, he advised her to temporarily leave him until they meet again. When Barbara sees Gordon and Leslie together, she becomes heartbroken and later psychotic. When the gang war reaches climax, Gordon and Bullock attempt to save Carmine Falcone. He, Falcone, Oswald and Butch Gilzean are captured by Fish Mooney and her gang. When Sal Maroni advises her to join, calling her "babe", she shoots him. Gordon manages to end gang war, but Cobblepot kills Fish Mooney in her apparent death when she falls in the river, becoming a new king of Gotham.
Six months after the gang war, in the second season, Jim is fired by Loeb after scolding police cop Franks, in addition getting a revenge on him. He returned on duty thanks to Cobblepot who accepted to help him. Jim soon faces a criminal group The Maniax, led by Jerome Valeska, the latter killing a new police commissioner and a former captain Sarah Essen. After Jerome was killed by Galavan, he soon joins to new commissioner Nathaniel Barnes, in creation of GCPD unit Strike Force to better fight against crime, terrorism and corruption in Gotham. Gordon later discovers that some cases are masterminded by a billionaire and mayor's candidate Theo Galavan and his sister Tabitha. Initially unaware of his schemes, Jim realizes this after Cobblepot tells him that his mother was captured and later killed when Oswald was coerced to work for them. He soon faces him and a religious group The Order of St. Dumas who intend to kill Bruce Wayne as a revenge for their injustice for Galavan's (Dumas) dynasty in the past. When the Order was finished, Gordon later kills Galavan. A month after Galavan was killed, Gordon was put in testimony to the court, telling them that Oswald killed Galavan. This backfires when a former forensic, now rogue criminal Edward Nygma discovers a source who got a clue of Galavan's murder, a cop named Carl Pinkney. Exploiting it, Nygma gets the contact and kills him, framing Gordon for murder and putting him in Blackgate Penintentiary. He escapes from a corrupt warden Carlson Grey (with the help of Bullock, Carmine Falcone and his contacts), later knowing it was Nygma, finally arresting him and Nygma going into Arkham. During that time, Gordon soon goes into the conflict with a new director of Arkham, a scientist Hugo Strange, who makes inhuman experimentations in Indian Hill, including the resurrections of Theo Galavan and Fish Mooney. Gordon learns that Hugo Strange hired the hitman Patrick "Matches" Malone to kill the Waynes when Hugo was friends with, but later betrayed them. Gordon, Bruce and Lucius Fox enter the Arkham to take down Strange and his workers, accidentally releasing the "monsters" on the Gotham's streets. They also save Selina Kyle who was searching for a friend called Bridget Pike. After the conflict with Hugo Strange at Arkham Asylum, Gordon left Gotham to find Leslie Thompkins, who had left Gotham, only later discovering that she was in a new relationship with Mario Calvi, discouraging him from pursuing her.
Six months later, in Season 3, Gordon is working as a bounty hunter, forming an uneasy alliance with reporter Valerie Vale. After experiencing a hallucination of his father, Gordon decides to rejoin the department. After Mario is infected by Alice Tetch's poisonous blood, Mario manipulates Lee into turning against Gordon. Before Mario can kill Lee, Gordon kills him in self-defense. This destroys any relationship Jim or Lee ever had. As his career goes on, Jim finds out his father and Uncle Frank were members of the Court of Owls. After Frank reveals he killed Gordon's father to prevent him from spreading info about the Court, Frank commits suicide, but not before telling Gordon that he must join the Court. Gordon takes the blame for Frank's death and meets with the Court.
After saving some of his fellow police officers and some of Oswald Cobblepot's men from Professor Pyg, Jim is promoted to captain by mayor Burke.
Following the defeat of Bane and Nyssa al Ghul, Jim Gordon is promoted to police commissioner by Mayor Cheng. His relationship with Lee blooms-up again and the two of them get married.
10 years later, Jim is planning to step down until Batman saves his daughter from Jeremiah.
Harvey Bullock (portrayed by Donal Logue; season 1–5) is a detective who is Gordon's loyal partner and ally. Bullock is a seemingly corrupt and brutish detective who has gradually become loyal to Jim Gordon. He also had a somewhat amicable relationship with Fish Mooney before turning against her. Bullock helps Gordon in solving various cases and later enters in a gang war near the end of the first season.
At the beginning of the second season, Bullock resigns from the police force but rejoins following the Maniax attack on the GCPD. After Gordon is framed for the murder of Carl Pinkney, Bullock enlists Carmine Falcone to help break Jim out of prison. After Captain Barnes is hospitalized after an attack by Azrael, Harvey is declared the de facto Captain until further notice and is trusted by Jim to protect Gotham after new threats emerge while he is away.
Six months later, Harvey is working with Barnes to protect Gotham and while Jim refuses to return to the department, Harvey vows to never turn his back on him. When Nathaniel Barnes gets infected with the Alice Tetch virus and is remanded to Arkham Asylum, Harvey becomes the acting captain.
In light of being promoted to captain by Mayor Burke after saving some police officers and some of Oswald Cobblepot's men from Professor Pyg's trap, Gordon reluctantly relieves Bullock of his position of acting captain.
In the series finale 10 years later, he is framed for murder, only for Gordon to deduce that it was a setup by Jeremiah, whom Bruce then subdues during his first outing as Batman. At the end of the episode, Bullock joins Gordon in witnessing Batman watching over them.
Bruce Wayne (portrayed by David Mazouz; season 1–5) is the orphaned son of Thomas and Martha Wayne, who is under the care of Alfred Pennyworth. Traumatised by the murder of his parents, which he witnessed, Bruce has been doing his part to find the identity of his parents' killer, while showing concern of some illegal activities performed by members of his father's company.
Bruce displays a fervent tendency to train himself as investigator and combatant but is still navigating the remainder of his childhood with Alfred's guidance.
After he is kidnapped by the Court, Bruce finds himself in a dungeon surrounded by snowy mountains. Meeting a Shaman there, Bruce begins his combat training. After breaking free from Ra's al Ghul's control, Bruce makes plans to protect Gotham City.
In the series finale, set 10 years after main events of the fifth season, the adult Bruce goes on to fight crime as the masked vigilante Batman. In his first outing under this persona, he apprehends Penguin and Riddler, helps Gordon rescue his daughter by defeating Jeremiah Valeska, and has an emotional exchange with Selina Kyle before silently observing Gordon, Bullock, and Alfred from a distance.
Oswald Cobblepot / Penguin
Oswald Chesterfield (Kapelput) Cobblepot (portrayed by Robin Lord Taylor; season 1–5) is a cunning, well-spoken criminal "snitch." He starts out as an attendant for Fish Mooney at her nightclub, and early on displays a sadistic, violent streak despite his small size. After he is discovered to be an informant for the GCPD, he is brutally beaten, leaving him with an odd way of walking furthering his nickname "Penguin". He escapes an attempt on his life, collaborating with Don Falcone when Gordon deliberately misfires at the pier where Oswald has been sent for execution. After a stint in the Maroni crime family as a restaurant manager, he convinces Maroni of his loyalty, even setting up a robbery by some actors in which he feigns heroism to show his devotion. He later kills the three actors with poisoned cannolis and presumably keeps the stolen cash they had on them. Oswald later assumes Mooney's position in the Falcone crime family when Mooney's plot against the Don is uncovered. At the end of season one, Oswald is Gotham City's sole remaining mob boss, with all of his rivals either dead, missing, or having fled Gotham.
Theo Galavan and Tabitha kidnap his mother, forcing him to help them. After they kill her, Oswald swears revenge and is later wounded during an attack on an event where Theo is holding his victory party for his election. After recuperating at Edward Nygma's place, he and Gabe follow Theo Galavan's henchmen where they save Jim Gordon from him. After the battle against the Saint Dumas, Oswald knocks out Nathaniel Barnes and convinces Gordon that Theo may never be convicted and must be killed. He and Jim then take Galavan to an isolated area, and Oswald mercilessly beats Galavan for killing his mother, before Gordon finishes Theo off with a gunshot.
After Theo's death, Oswald's men abandon him, and he is later found and arrested by the GCPD. After telling Barnes he's "insane," Oswald is taken to Arkham Asylum, where he meets Hugo Strange. After noticing and asking a fellow inmate at Arkham, he later finds out that he is to be experimented on. Following some experiments, Oswald is released from Arkham. He later meets his biological father Elijah Van Dahl when visiting his mother's grave. After his step-family murders Elijah to gain the family's fortune, Oswald awakens from his condition and slaughters his step-family in vengeance. After finding out that Azrael happens to be the resurrected Theo Galavan, Oswald and Butch kill Galavan with an RPG. After finding out about Hugo Strange's experiments, Oswald, Butch, and his gang knock down the bus supposedly containing Strange, but a shocked Oswald is knocked out by a resurrected Fish Mooney, prompting Butch and the gang to flee.
The third season of Gotham explores Oswald's continued struggle against the monsters, a final confrontation with Fish Mooney, and his rise and fall as Mayor of Gotham. After working with Edward Nygma to get into office, Oswald develops romantic feelings for him, resulting in consequences within the political and criminal worlds of the city. After his downfall, Oswald forms an alliance with Ivy Pepper and exacts revenge on those who betrayed him.
Upon establishing the Pax Penguina where criminals can get a license from him to commit a crime, Oswald Cobblepot has his encounter with Sofia Falcone. After figuring out Sofia's plot, Oswald ends up in a gang war with her. Later on when Gotham City becomes a no man's land, Oswald kills Butch Gilzean as part of his revenge on Tabitha for killing his mother. He then has Hugo Strange work on saving the lives of Leslie Thompkins and Riddler while he claims some territory.
10 years later, Penguin is released from Blackgate Penitentiary. He tries to shoot Gordon at the pier only to fail. After helping to rescue Riddler, Penguin drives off with him only for them to be defeated by Bruce Wayne in his first outing as Batman. En route to their incarcerations, Penguin and Riddler escape and plan to get revenge, but when they see their new enemy using a grappling hook to glide between rooftops, they decide to start the next day.
Barbara Kean (portrayed by Erin Richards; season 1–5) is the daughter of a wealthy couple and the owner of an art gallery. Barbara Kean is the ex-fiancée of James Gordon. It is also revealed that this version of Barbara Kean is bi-sexual and for a year before the start of the series was in a lesbian relationship with Renee Montoya. After a hiatus from Gordon following attempts on her life by the Maroni and Falcone crime families, Barbara stayed with Renee Montoya. It is also revealed that they were once again in a sexual relationship for a time, and her parents, before planning to rekindle her relationship with James Gordon. Barbara even befriends Selina Kyle and Ivy Pepper when they took refuge in her penthouse. After finding out that Gordon had moved on to a relationship with Leslie Tompkins, Barbara later had a romantic encounter with the wealthy Jason Lennon, the serial killer known as the Ogre. She was severely traumatized after she was kidnapped by Lennon and forced to murder her own parents. The Ogre's malevolent insanity appears to live on in her psyche. When she attempted to kill Leslie during an informal counseling session, the latter rendered her unconscious.
She was incarcerated in Arkham Asylum until she is among those sprung from Arkham Asylum by Tabitha Galavan on her brother Theo's orders, with Barbara and Tabitha starting a new lesbian relationship. A convoluted and failed attempt on Gordon's life at Gotham Cathedral occurs when Barbara wears the wedding dress she had originally ordered for their wedding and has Arkham escapees as priest and witnesses. During an apparent last attempt to kill Gordon, Barbara falls out a window and is grabbed by Gordon. She lets go and falls, ending up in the hospital and put into some sort of induced coma before being transferred to Arkham Asylum's medical wing. When news of James Gordon being found guilty and being sentenced to 40 years at Blackgate Penitentiary is heard on Arkham Asylum's radio, Barbara awakens from her coma. A nurse notices this and shouts for someone to get Hugo Strange. Hugo Strange later releases Barbara from Arkham so that he can study her. After helping Gordon get info about who contracted the hit on Thomas Wayne and Martha Wayne, Barbara found her way to where Butch Gilzean and Tabitha Galavan were residing. Butch later kicks Barbara out. She later exposes "Gordon" at the Police Station as being an imposter when visiting the Police Station, thus causing Harvey Bullock and Alfred Pennyworth to quickly realize the real Gordon alongside Bruce Wayne and Lucius Fox were being held at Arkham Asylum.
Six months later, Barbara and Tabitha have opened Sirens Nightclub, and while she and Barbara are shown to be in a romantic relationship, she still harbors some feelings for Gordon. After Barbara learns that Penguin has romantic feelings for Nygma, she informs Nygma of this after correctly deducing that Penguin killed Nygma's girlfriend, Isabella. Afterward, Nygma forms a partnership with Barbara, Tabitha, and Butch to destroy everything Penguin loves. After Nygma shoots Penguin in the harbor docks, Barbara is hired by Jim to interrogate a worker in the dock to find info on a Court weapon. Before they can get more info, Barbara and Tabitha are attacked by Talon, who kills their henchmen, although Barbara and Tabitha managed to escape.
As the chaos caused by the Alice Tetch Virus comes to a close, Barbara (apparently) kills Butch, having heard his and Tabitha's plans to betray her. During a fight against Tabitha at her safe house, Barbara ends up being electrocuted to death.
She later returns to life upon Ra's al Ghul bathing her in the Lazarus Pit as she tries to get Tabitha Galavan and Selina Kyle to work for her in an arms race against Cobblepot while targeting an embalming knife. When Ra's al Ghul was in Blackgate, he transferred some energy for Barbara Kean to use at a later date.
After the incident with the Speed Demonz biker gang, Oswald Cobblepot sends Barbara Kean, Tabitha Galavan, and Selina Kyle to the Narrows to bring him Edward Nygma. When Firefly crashes the fight between Tabitha Galavan and Solomon Grundy, Barbara Kean shoots Cherry after Leslie Thompkins disabled Firefly. Barbara Kean then declares to the crowd that they are defecting from Cobblepot's services. After abducting Sofia while thinking that she is on Cobblepot's side, Barbara learns that Sofia is against Cobblepot while seeing that she was right about her claim when Victor Zsasz uses a rocket launcher to destroy her lair. Afterward, Barbara, Tabitha, and Selina side with Sofia in her war against Cobblepot.
The energy that Ra's al Ghul placed in Barbara Kean turned out to be a beacon for the rest of the League of Shadows as they arrive at The Sirens club. After relinquishing it to a revived Ra's al Ghul, she assists Alfred Pennyworth in rescuing Bruce Wayne as she manipulates events that have her forcing Bruce Wayne's hand into thrusting the embalming knife into Ra's al Ghul. After hearing from Tabitha about Butch's death at the hands of Oswald Cobblepot, Barbara blames men for the troubles they have been dealing with and decides to kill the males from the League of Shadows that offered to follow her after Ra's al Ghul's defeat.
A few weeks after the government abandons Gotham, Tabitha is killed by Penguin, and an enraged Barbara vows revenge. She later rescues Jim while he is on a mission to rescue children being used for slave labor and then has a one-night stand with him. Barbara becomes pregnant with his child, and she requests that Lee provides prenatal care for her. Barbara gives birth to a daughter, and after giving birth, she and Lee are chased by Bane at the request of Nyssa al Ghul for her involvement in her father's death. Once Bane is defeated, she reveals that she named her daughter Barbara Lee after the people she trusts the most. She ends her feud with Lee Thompkins, and Jim, Lee, and Barbara all agree to raise the child together.
10 years later, Barbara is no longer in the criminal business where she now sports red hair and was working on a tower to outdo the size of the rebuilt Wayne Tower. After discovering a plot to blow up Wayne Tower, she helps Selina Kyle to subdue Riddler and then helps disarm the bombs. Then, Barbara picks up her daughter and goes to get a gun from the Sirens, but is ambushed by Jeremiah and Ecco. After stabbing Ecco, Barbara is subdued by Jeremiah and has her leave a message for Gordon while making off with Barbara's daughter. Luckily, when Gordon goes after Jeremiah, although they are almost killed, Jim and Barbara Lee are saved when Batman arrives.
Sarah Essen (portrayed by Zabryna Guevara; season 1–2) is the Captain of the Gotham City Police Department's homicide squad and the boss of James Gordon and Harvey Bullock. She is an honest cop that wants to do something about the rampant corruption in her department, but fears for her family's safety.
Following Gillian Loeb's resignation, Sarah Essen is sworn in as the new police commissioner. She is later killed by Jerome Valeska during the Maniax's raid on the Gotham City Police Department.
Alfred Pennyworth (portrayed by Sean Pertwee; season 1–5), an ex-Special Air Service operative, is the butler and legal guardian of Bruce Wayne. Though technically Bruce's legal guardian, Alfred is still more willing to go along with Bruce's whims of investigating leads to the murder of his parents. Alfred is teaching Bruce basic self-defense.
At one point, he even let Bruce use his father's watch as improvised brass knuckles to beat up Thomas Elliot for insulting the late Waynes. He often helps Bruce and Jim with certain situations. Although he still looks after Bruce, Alfred allows him to go his own way sometimes.
During the chaos caused by the Alice Tetch Virus outbreak, Bruce stabs Alfred and then uses the Lazarus Pit's waters to cauterise the wound as Alfred recuperates in the hospital.
Following the incident where Bruce ended up having to stab Ra's al Ghul with the embalming knife, Alfred works to get Bruce back to normal when he starts partying with his friends from school.
When Gotham City is made a no man's land, Bruce persuades Alfred to be evacuated with a recuperating Selina. Alfred vows to come back when Selina fully recovers.
10 years later, Alfred represents Bruce at the opening of the new Wayne Tower. After being with Lucius when the police find Penguin and Riddler tied up, Alfred goes to the rooftop of the Gotham City Police Department and witnesses Gordon and Bullock's first sighting of Bruce as Batman.

Selina Kyle (portrayed by Camren Bicondova; season 1–5, Lili Simmons in "The Beginning...") is a young street orphan and skilled thief who was a childhood friend of Bridget Pike. Since witnessing the murders of Thomas and Martha Wayne while memorizing what the murderer looked like without the mask, Cat has been lingering around the borders of Wayne Manor which leads to her befriending Bruce Wayne. Cat also has connections with Ivy Pepper and later befriends Barbara Kean. During the gang war between Carmine Falcone and Sal Maroni, Selina is among the street children recruited into Fish Mooney's gang. When it came to Oswald Cobblepot's fight with Fish Mooney, Selina disappeared during the conflict.
She later appears as part of Cobblepot's gang and develops a rivalry with Silver St. Cloud for the affection of Bruce. Selina later helps Bruce to expose Silver and find a hint to who killed his parents while also helping to rescue Bruce from the Order of St. Dumas. She allowed Bruce to live on the streets with her for a while until Gordon ended up on the lam and played a part in Edward Nygma's arrest. When Bruce decided to go back home, Selina to storm out in anger. Selina later infiltrated Arkham Asylum to find Hugo Strange's experiments and a newly reformed Pike, calling herself Firefly, after being told about her survival by Bruce. Selina later asks to be Firefly's servant and is released later from Arkham after freeing Gordon, Bruce, and Lucius.
Selina is later shown to have re-aligned with Fish Mooney following her revival. When one of Fish Mooney's minions catches Ivy, Selina tries to intervene which led to her witnessing Fish Mooney's minion Marv touching Ivy prior to her falling into the river.
Unable to get Bruce's help to find Ivy, Selina is approached by James Gordon if she knows any info about Alice Tetch. She did tell him that she was a one-time member of Fish Mooney's latest gang before she parted ways with her. Later on, she encounters Subject 514A who was posing as Bruce Wayne. While suspicious about Bruce Wayne's look-a-like, Selina decides to go out to dinner with him. Eventually, after 514A saves Selina after she fails to rob a bar, she sees 514A's scars and realizes he isn't Bruce. 514A explains the situation, and Selina tells him he's more normal than Bruce. With that, 514A kisses Selina and the two part ways. Later, while Selina is stealing wallets at the Penguin's party, she encounters an older Ivy, though she doesn't recognize her. After Bruce confesses his feelings for her, Selina kisses him. Once Ivy reveals herself, Selina is shocked and unclear of whether she and Bruce are in a relationship or not. After trying to help Bruce and Alfred break into a Court building, they are assisted by Selina's long-lost mother. Although Selina's mother seems to want to reconnect with her daughter, Selina later discovers that her mother only returned to extort money from Bruce Wayne. Selina then tearfully tells her mother to never return to Gotham. Selina gets mad at Bruce once she finds out he kept it from her. Later, however, Selina and Bruce show some signs of reconciling.
Upon her latest encounter with Subject 514A and being surprised that Bruce is not in Gotham City, Selina tries to warn Alfred only to be pushed out the window by 514A. The stray cats then swarm over her body. Her body was found by the police and was taken to the hospital. Thanks to Ivy Pepper's plants, Selina recovered and plans to go to Wayne Manor to get revenge on Subject 514A. Even though she and Alfred fail to defeat Subject 514A, Selina wasn't interested in helping Alfred find Bruce.
After her friendship with Bruce is strained during the chaos caused by Alice Tetch Virus and Alfred getting stabbed, Selina meets up with Tabitha Galavan where she tests her talents on Tabitha's whip upon telling Tabitha that she is "done just surviving". Eventually, Selina and Tabitha work for a revived Barbara Kean after she made amends with them even when Barbara aligns herself with Sofia Falcone. Though she reconciles with Bruce, Selina is later shot in the waist by Jeremiah Valeska, leaving her with a severed spine. When Gotham City becomes a no man's land, Bruce convinces Alfred to go with Selina to oversee her recovery.
Many days later, Selina has undergone an operation to keep her spine from collapsing. After an attempt to take her life is thwarted by the doctors, Bruce takes the advice of a nurse to seek out "the witch" as he asks where to find her. Selina gets healed and later assists Bruce and Gordon in their fight against Jeremiah Valeska and Delta Force. She is saddened by Bruce's decision to leave the city soon afterward.
Ten years later, Selina has become a jewel thief. She attends the opening of the new Wayne Tower and drags Barbara into subduing Riddler, who has been manipulated by Jeremiah to bomb the building. Later that night, Selina has an emotional exchange with Bruce, whom she deeply misses, in his first outing as Batman. Before leaving, Batman advises Selina to return a diamond she had stolen. After he leaves, Selina mutters "like hell."

He initially starts off as an awkward but intelligent man with an unrequited crush on archivist Kristen Kringle, but over the course of the show, transforms into a murderous and manipulative criminal. After being constantly mistreated by his fellow co-workers (except Bullock and Gordon, who tolerate him), Nygma murdered a fellow officer, Tom, who was also Kringle's abusive boyfriend causing a mental breakdown that results in a second personality. He succeeded in becoming Kristen's boyfriend, however he was dumped after he told Kristen about having killed her abusive ex-boyfriend, Tom.

Riddler then helps Bruce, Alfred, Barbara, and Lucius reclaim the Gotham City Police Department. In a hazmat suit, Riddler did a bomb ruse where the code is provided by the answer to how many times a Pallid beach mouse can give birth in a year.

He is later arrested by Jim Gordon after Mayor James is found alive following Barbara Kean ending up hospitalized. While Gordon and Barnes were searching Galavan's apartment, they did find a cassock behind one of the paintings where they assumed that Galavan had some religious connections. While awaiting trial, Theo reprimanded Tabitha for acting out against his orders and states that his next plan is in motion.
