Main characters

Introduced in Season 1

• James Gordon (portrayed by Ben McKenzie) – 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 James was 13 years old. 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". After the conflict with Hugo Strange at Arkham Asylum, Jim left Gotham to find Lee, who had left Gotham.
• Harvey Bullock (portrayed by Donal Logue) – A detective who is Gordon's loyal partner and ally. Bullock is a seemingly corrupt and brutish detective who has gradually become loyal to James Gordon. At the beginning of the second season, Bullock resigned from the police force, but rejoins following the Maniax attack on the GCPD. After Gordon was framed for the murder of Theo Galavan and Carl Pinkney, Bullock, with the help of Carmine Falcone, broke Jim out of prison. After Captain Barnes was hopitalized after an attack by Azrael, Harvey was declared de facto Captain, and was trusted by Jim to protect Gotham after new threats had emerged.

Traumatized 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 done 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. In a later life, Bruce will go on to fight crime in his adulthood as Batman.
• Oswald Cobblepot/The Penguin (portrayed by Robin Lord Taylor) – A cunning, well-spoken criminal "snitch", he also has a profound Oedipus complex, being unhealthily close to his rather misogynistic mother Gertrud. 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 a 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 fled Gotham.

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.

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, Penguin and Butch kill Galavan with an RPG.

He is responsible for creating chaos and violence in Gotham City, as part of his master plan to finally carry out a centuries-old vendetta. Galavan's family, originally called the Dumas family, were one of Gotham City's most prominent families and said to have built Gotham City. But the family was ruined financially and socially by the Wayne family after an act of violence was perpetrated by a member of the Dumas family against a member of the Wayne family many years earlier. Those Dumas who remained in Gotham changed their surname to Galavan. Theo poses as a caring father figure to Bruce Wayne after ostensibly saving him from a psychopath named Jerome Valeska and extorts Oswald Cobblepot into killing one of the other mayoral candidates by holding Oswald's mother, Gertrud, hostage. The other candidate survives but goes into hiding. As the only remaining candidate, Theo wins the election, but his true goal is to avenge the Dumas family against the Wayne family. He is later arrested by Jim Gordon after Mayor Aubrey James (whom he kidnapped) is found alive. Mayor James testifies in court, however, that it was Oswald Cobblepot who abducted him. The judge drops the case against Theo, whose henchmen, posing as police officers, abduct Gordon. With Gordon in his clutches, Galavan stated that the Order of St Dumas protected his family and that his real surname is Dumas. Galavan toys with Gordon but quickly overpowers him, using some martial arts skills which Theo not previously displayed. He orders his henchmen to kill Gordon slowly and leaves to claim Bruce Wayne's life. During the final battle at Galavan's tower, Tabitha tells Theo he has lost and she is going to look out for herself, saving Silver and Bruce Wayne, as Gordon and Penguin come to the rescue, albeit for very different reasons. Gordon and Cobblepot take him to an isolated place outside Gotham where Cobblepot beats him mercilessly until Gordon stops him and shoots Galavan dead. Cobblepot puts an umbrella in the corpse's mouth to make it look like that he killed Galavan. Galavan's body is then taken to the underground Indian Hill facility. As Patient 44, he is successfully resurrected by the Indian Hill facility's doctors but the shock of the process scrambled his memories.

During the fight between Gordon and Kean, Tabitha was shot in the shoulder and managed to escape. When it comes to the battle between Oswald Cobbleport's group and the Order of St. Dumas, Tabitha turns against Theo telling him he has lost and that she needs to look out for herself as she escapes with Silver. Four weeks later, Tabitha visits Butch Gilzean and becomes his partner while starting a relationship with her.

After Gordon becomes a fugitive for punching Theo Galavan in court after being found innocent, Barnes attempts to arrest Gordon after the battle with the Order of Saint Dumas, but is knocked out by Cobblepot. After Cobblepot was apprehended and backed up Gordon's claim, Barnes told Gordon not to make a fool out of him.

After Jim was proven innocent, Barnes apologized and told Jim he owed him a favor. He also gave Jim the remaining Wayne files and Lee's number.
