Main characters

Jake Peralta

• Andy Samberg as Detective Jacob Peralta, a talented but childish detective. Peralta shows "class clown" traits, constantly pulling pranks and making immature jokes at the expense of his colleagues, particularly his partner, Amy Santiago. He is fun-loving and sarcastic but is often motivated by his emotions more than his colleagues. Despite his goofy traits, Peralta is extremely smart, perceptive and quick thinking, and as such has the best arrest rate in the precinct. In the pilot, Terry Jeffords explains to Captain Holt that Peralta is his best detective, that he likes putting away bad guys, and that he loves puzzles, although "the only puzzle he hasn't solved is how to grow up." As of season one, he is 33 years old and has been a detective with the 9-9 since 2005.^[1]

His father left his family during his childhood and, as a result, he feels a strong tie to memories involving his father, such as his favorite Brooklyn pizza joint. He also initially refuses to celebrate Thanksgiving, since he associates the holiday with his father's absenteeism. He has a strong emotional tie to his poorly made, low-quality sports car, which he bought outright on his first day as a cop and always carries a positive association for him (until he sold it to help pay for Terry's new child). He often quotes and makes references to his favorite movie, Die Hard. In "Boyle-Linetti Wedding" it is revealed that Jake is Jewish, having lost his childhood sweetheart Jenny Gildenhorn to Eddie Fung at his Bar Mitzvah.

Peralta's closest friend in at the precinct is Charles Boyle, who admires Peralta and encourages his eventual romance with Santiago. Peralta and Gina Linetti are childhood friends, which resulted in him helping Gina get a job at the precinct. Diaz and Peralta were classmates at the police academy.

Jake began his career as a patrol officer with the 74th Precinct and was partnered with Stevie Schillens and the two nicknamed themselves the "Beatsie Boys"; in 2016, Jake was forced to arrest Stevie, now a detective with the neighboring 98th Precinct for planting evidence.^[2]

While Jake doesn't initially approve of Captain Holt's strict management, he eventually matures under Holt's supervision and comes to see Holt as a father-figure; even calling him "Dad" on many occasions. In "The Oolong Slayer", Jake achieves his lifelong dream to catch a serial killer, the Oolong Slayer, but gives up the credit for the arrest to the Chief of Brooklyn Detectives in exchange for getting Holt transferred back to the 99th Precinct.^[3]

At the end of season four, Jake and Rosa Diaz are framed by their idol Lt. Melanie Hawkins and are arrested. After months in prison at the beginning of season five, the two are freed thanks to the precinct exposing Hawkins' crimes. Although he is eager to return to work, his time in prison left him with some post-traumatic stress that affected his job performance.

Peralta continuously pranks and teases his partner Santiago, masking his secret romantic feelings for her. Peralta confesses his feelings to her in the season one finale before going undercover for a mafia operation. His romantic feelings for her develop further throughout season two and they share their first kiss in "Johnny and Dora".^[4] Jake and Amy start dating in "New Captain" and decide to move in together in the season three finale "Greg and Larry", but don't make it official until season four's "The Fugitive". Jake proposes to Amy at the end of their annual Halloween heist in "HalloVeen" and the two are later married by Captain Holt in the finale of season five.^[5]

Awards and decorations

The following are the medals and service awards fictionally worn by Detective Peralta.

In "Stakeout", he received a commendation for his work on Rosa's drug task force.

Rosa Diaz

• Stephanie Beatriz as Detective Rosa Diaz, a smart, tough, aloof, and mysterious detective. She attended parochial school, later studied ballet, and was a classmate of Jake's in the police academy.^[7] Though Diaz is a loyal and effective member of the squad, her anger management issues and lack of empathy terrify most of her coworkers. She is highly secretive about her personal life – should anyone discover a secret of hers, she normally threatens them with death should they disclose it. It is also made clear that she does not stay in her apartments for long periods of time, and her neighbours know her by both a different name and a completely different personality. As revealed in "Cop-Con", she and Amy are younger than most of the other precinct members as they are hurt by a device that emits a loud noise to those under 35, whereas Jake and Boyle only pretend to be affected by it. In "White Whale", she reveals to Amy that she's attended medical school, business school, and has a pilot's license.

In season two, Rosa dates Captain Holt's nephew, Marcus, but breaks up with him in season three. Later in the season, she finds love with former undercover detective Adrian Pimento; the two get engaged in "Paranoia" while chasing a drug dealer through an alley, but their wedding is delayed when Pimento is targeted by Figgis and forced to leave the state. Once he returns, they try to have their wedding the next day, but decide to go steady after realizing they were rushing their relationship.

At the end of season four, Rosa and Jake are framed by their idol Lt. Melanie Hawkins and are arrested. After months in prison at the beginning of season five, the two are freed thanks to the precinct exposing Hawkins' crimes. Following her months of isolation, she starts spending more time with her family and ends her relationship with Pimento. Later in the season, she comes out as bisexual to the precinct and her family, and has a brief relationship with an unseen woman that the squad never meet or learn the name of, nicknamed "Becky". She has a brief flirtation with one of Gina's friends, but this does not lead anywhere. On the day of Jake and Amy's wedding, she and Terry meet a cab driver named Alicia that she becomes interested in. The two begin a relationship off-screen. However, it's short-lived, as Rosa mentions in "The Tattler" that they broke up because Alicia was moving to London.

In "The Crime Scene" Rosa mentions she has a girlfriend named Jocelyn. Rosa makes an effort to patch things up with her mom, who was ignorant and unaccepting of her bisexuality. Jocelyn isn't mentioned again until her first appearance in "The Therapist".

In "Stakeout", she received a commendation for her work as the leader of a drug task force.

Terry Jeffords

• Terry Crews portrays Sergeant Terrence Vincent Jeffords, the supervisor of the 9-9's Detective Squad. An avid bodybuilder who stands at more than six feet tall, with a linebacker's build, Terry's intimidating size and appearance is contrasted by his caring, protective nature and paternal instincts. Jeffords is devoted to his wife and three young daughters Cagney, Lacey (named after the stars of the 1980s TV series),and Ava. He fears the danger of police work because of the possibility that he could leave his children fatherless. Following a panic attack prior to the show's beginning, Terry was removed from field work, but he has since cautiously returned. He is high-strung, prone to nervous excitement, loves yogurt, and has a tendency to refer to himself in the third person. He is an effective and caring leader to the detective squad, often having to play the mature adult in order to keep them in line.

A running gag throughout the series is for Terry to break things (examples include a Magic 8 Ball and a phone) because of his incredible strength. He has been a detective since 1995, and used to be assigned to the 65th Precinct (as seen in "Terry Kitties"), where he was constantly mocked for a botched case which he and Jake later proved he was correct in. In 2005, he was the senior detective at the 9-9 (the position Jake now holds since Terry's promotion). He was a linebacker at Syracuse University, where he graduated magna cum laude, as revealed in "The Swedes". He also studied abroad in Japan while in college and dated a Japanese student named Chiaki who broke his heart.

In season two, Terry nearly gets a vasectomy at his wife's request, but Jake convinces him not to when he finds out Terry secretly wants to have more kids. His wife becomes pregnant later in the season and gives birth to their third daughter, Ava, in season three. He entrusts Jake to be Ava's godfather.

While Terry is satisfied with his role as Sergeant, he does aim to become a Lieutenant in the future. As revealed in "The Honeypot", he brought a new pair of suspenders that he planned to put on after he passed the Lieutenant's exam, but kept them in the box when he ended up failing and held onto them as a reminder of his higher goals. In "Moo Moo", he attempted to apply to be a city council liaison to take on more responsibilities, but was rejected after reporting that another cop racially profiled him.

Amy Santiago

• Detective {{small|(seasons 1–5)}}
• Sergeant {{small|(season 5–present)}}

• Melissa Fumero portrays Sergeant Amy Santiago, Jake's uptight, by-the-book, rule-following Cuban-American partner, and later wife.^[7] A neurotic overachiever, she is continually trying to ingratiate herself with Captain Holt, and any authority figure in arm's reach of her. Terry at one point explains to Holt that Amy's competitiveness is a result of her having seven brothers. Amy is a stickler for department protocol and is frequently exasperated by Jake's childishness, as well as the ease with which he succeeds as a detective. She is initially seen as Holt's teacher's pet, but over time is shown to command respect from others.

Amy was originally a patrol officer at the 64th precinct, but requested a transfer to the 99th when her captain almost sexually assaulted her shortly after her promotion to detective. She didn't tell anyone for years out of fear for what it would do to her career until she revealed it to Jake when they were investigating a sexual assault case in "He Said, She Said".

In "Charges and Specs", the season one finale, Jake confesses that he wishes something romantic could happen between them. She confesses to having had feelings for Jake in "The Road Trip" and is shown to still have feelings for Jake in "Det. Dave Majors". The two share their first kiss in "Johnny and Dora"^[4] and begin dating in "New Captain", although their working relationship does not change at all. They decide to move in together in the season three finale "Greg and Larry", but don't make it official until season four's "The Fugitive". Jake proposes to Amy at the end of their annual Halloween heist in "HalloVeen" and the two eventually marry.

Near the end of season three, Amy goes undercover as a pregnant inmate in a women's prison in Texas to obtain information from Maura Figgis. This was done to cover Melissa Fumero's actual pregnancy at the time without making her character pregnant.

In season five, Amy achieves her dream of being the youngest woman to pass the Sergeant's Exam. It is not known exactly how old Amy is, but she is under 35 as of the episode "Cop-Con", which makes her at least four years younger than Jake.

Awards and decorations

The following are the medals and service awards fictionally worn by Sergeant Santiago.

Charles Boyle

• Joe Lo Truglio portrays Detective Charles Boyle, a nervous and clumsy but honest and hard-working detective.^[7] He is Jake's best friend, and almost completely idolises him. He is divorced from his wife Eleanor, who had numerous affairs during their marriage, to the point where she has to pay alimony to him. He is also a huge, unapologetic foodie, maintaining a weekly Brooklyn pizza-ranking email and often relishing bizarre foreign cuisine that disgusts his coworkers.

For saving Detective Diaz's life during "Christmas" (during which he was shot in the buttocks), he was awarded the NYPD Medal for Valor in "The Bet", though he was overshadowed by a revered and heroic NYPD horse named Sgt Peanut Butter. In "The Swedes", it is revealed that Boyle is a graduate of Sarah Lawrence College.

In the show's first season, Charles has a crush on Rosa, but he eventually gets over her when he starts dating Vivian Ludley. They get engaged, but break up after Charles refuses to move to Canada with her. He and Gina start seeing each other in season two, and their brief relationship results in his father and Gina's mother getting married. In season three, he starts dating Genevieve Mirren-Carter after he and Jake clear her name from an art thief. They eventually move in together and adopt a son from Latvia named Nikolaj. In season five, Charles starts his own food truck business called "The One Thing", which specializes in meatball subs. The truck is burned down by one of Charles' ex-employees, but he's thankful it happened as running the food truck made him spend less time with his family and built up a large debt.

Awards and decorations

The following are the medals and service awards fictionally worn by Detective Boyle.

Gina Linetti

• Chelsea Peretti portrays Regina Linetti, the 99th Precinct's sardonic and egomaniacal civilian administrator and Captain Holt's assistant.^[7] Despite maintaining a clueless and dimwitted disposition most of the time, she can be surprisingly observant and has demonstrated traits of being more intelligent than she likes to show. Gina is obsessed with social media and is constantly on her phone. It is a running gag to try to pry her from her phone, to the point where Captain Holt becomes involved. She is extremely narcissistic and constantly praises and exalts herself, such as claiming to be a better dancer than Britney Spears in the episode "Karen Peralta". As the only civilian in the precinct, Gina often uses her outsider's perspective to assist the other detectives. In the episode "The Party", Rosa plays a prank on Gina by tricking her into talking to a group of psychology professors at Holt's birthday party, who then take copious notes about her narcissistic personality.

She casually admits on myriad occasions that she doesn't value her colleagues – except for Jake – as people. She was also childhood friends with Jake, who got her the job at the precinct. Gina also ruined Jake's senior year of high school by framing him as "The Tattler", though she did it to avoid Jake getting involved with the wrong crowd. She transferred to the Public Affairs Division with Captain Holt in "Johnny and Dora", and returns to the 9-9 with him in "The Oolong Slayer".^[4][3] In the episode "The Apartment", it is revealed that she has been engaged eight times, but never married. At the end of "The Fugitive Pt. 2", she gets hit by a bus after receiving a text from Charles. The penultimate episode of season four reveals she has become pregnant following a relationship with Charles' cousin, Milton (which coincided with Chelsea Peretti's actual pregnancy). She is absent for the first half of season five on maternity leave after giving birth to a girl she nicknames "Iggy" (short for Enigma). In season six, Jake helps Gina realize that her talents would be better spent elsewhere and she quits her job.

Raymond Holt

• Andre Braugher portrays Captain Raymond Jacob Holt, the 99th Precinct's strict Commanding Officer. Holt is known for his cold, calm and robotic manner of speaking, overly formal demeanour and lack of outwardly visible emotion, although his non-work friends frequently refer to him having a much more fun persona that is very rarely seen by either the Nine-Nine members, and the viewer. He has sophisticated and cultured interests, enjoying classical music, opera and attending dinner parties with his husband's academic friends, amongst other things. The Nine-Nine is Holt's first command despite many years of outstanding service, something he attributes to prejudice against both his race and homosexuality. He came out in 1987 and until recently led a group that supported gay African-American NYPD members, which he himself created.^[7] He was a homicide detective in the 1980s, and spent twelve years in the Community Affairs Bureau immediately prior to commanding the Nine-Nine.

Holt is married to Kevin Cozner, the Chair of Columbia University's Classics Department^[8] and has a longstanding professional rivalry with Madeline Wuntch, with whom he came up through the ranks; while his career stalled, she kept advancing and is now his immediate superior. After he and Peralta successfully solved a major case in "The Chopper", Bureau Chief Wuntch nominated him for a promotion to head of the NYPD Public Affairs Division, a promotion he accepted lest Wuntch transfer his staff to horrible posts around New York City.^[4] During the number of weeks he was in charge of Public Affairs, Holt was unable to accomplish anything significant thanks to Chief Wuntch's constant micromanaging. After helping Peralta solve a serial killer case, Holt found himself transferred back to command of the 9-9 by the Chief of Brooklyn Detectives.^[3] He owned a burgundy Chevrolet Corvair named Gertie which was his prized possession until it was stolen in 'The Fugitive'. Doug Judy purchased him a new identical one and named it Sexarella.

At the end of season three, Holt is forced to go into witness protection in Florida with Jake when they are threatened by crime boss Jimmy "The Butcher" Figgis. He worked at a family entertainment center called the Fun Zone under the alias of Greg until he and Jake baited Figgis into coming to Florida and took the criminal down with the Nine-Nine. In season five, his life and career are put at risk when he makes a deal with mobster Seamus Murphy in exchange for information to clear Jake and Rosa's names from Lt. Hawkins.

During season five, Holt learns that the New York City Police Commissioner is retiring at the end of the year and that he is on the short list of candidates to replace him. He spends the rest of the season campaigning to win the Commissioner title but ends up losing to John Kelly. In season six, Holt is encouraged by Jake and Amy to stand up to Kelly's regressive policies, leading the Commissioner to retaliate against the Nine-Nine.

Awards and decorations

The following are the medals and service awards fictionally worn by Captain Holt.

In "Stakeout", he received a commendation for his supervision of Det. Diaz's drug task force.

Michael Hitchcock

• Dirk Blocker portrays Detective 3rd Grade Michael Hitchcock (season 2—present; recurring season 1), an enthusiastic but clueless detective who has been best friends and partners with Detective Scully for over 30 years. Despite their inept nature, Hitchcock and Scully have both shown on occasion to be competent and even good detectives, though their laziness tends to keep them from demonstrating this most of the time. As revealed in "Hitchcock and Scully", the two were excellent detectives in their youths and had well-built bodies, but their careers and their physiques went downhill after trying the wings at their eventual favorite restaurant, Wing Slutz.

The majority of the precinct tends to be disgusted by Hitchcock's more perverted nature and attitude towards women. It's revealed in "The Last Ride" (Season 4) that Hitchcock held the all-time record for closed cases at the 99th Precinct, one more than Sgt. Jeffords as of that episode. This is mainly due to Hitchcock being at the 99th twenty years longer than Terry. To celebrate, Hitchcock got a tattoo of himself holding a gun and putting it in his mouth, oblivious to what it actually implies.

Norm Scully

• Joel McKinnon Miller portrays Detective Norm Scully (season 2—present; recurring season 1), a middle-aged, lazy and overweight desk worker who has been best friends and partners with Detective Hitchcock for over 30 years. Scully shows talent as a tenor opera singer, French speaker, having an understanding of Morse code and can "make great coffee", according to Sgt. Jeffords. Scully routinely discloses disgusting medical issues like the entire bottom of his foot being a wart or having various strains of fungi. He claims to constantly have medical emergencies, and despite having a pacemaker fitted, he frequently suffers from heart attacks. He is dating Cindy Shatz, who is very similar to him in her attire and personality.

Recurring characters

NYPD and other law enforcement

• {{anchor|Fire Marshal Boone}}Patton Oswalt as FDNY Fire Marshal Boone, the fire marshal of the local fire station.

• {{anchor|The Vulture}}Dean Winters as Detective Keith Pembroke, nicknamed "The Vulture", a detective in the Major Crimes Unit notorious for taking over cases that are nearly solved and getting all of the credit for closing them. He frequently makes lewd comments toward the squad and has a greatly inflated sense of self. After the death of Seth Dozerman, Pembroke becomes the Commanding Officer of the 99th Precinct until Captain Holt returns. In "The Venue", the Vulture steals Jake and Amy's venue at the last second to host his wedding to a kind charity worker named Jean Munhroe. When the two discover that he is unfaithful to Jean and lying to her about his character, they decide to tell Jean at the cost of Vulture taking their venue on their wedding night. He is a recipient of the American Flag Breast Bar, World Trade Center Breast Bar, NYPD Medal of Honor, and Marine Corps Service Award.

• {{anchor|Teddy Wells}}Kyle Bornheimer as Sergeant Teddy Wells, a detective at the 82nd Precinct. Teddy used to date Amy Santiago; they resume their relationship after meeting up at a training exercise. Later Amy breaks up with him again, because she dislikes his dull personality and is unable to show interest in his home pilsner-brewing hobby. In season four, Teddy evaluates the Nine-Nine when the crime rate drops and one precinct has to close. He claims to have changed but Jake and Amy agree that he is still "The most boring man in America". He also admits to Amy that he still loves her and proposes to her twice; once in front of his new girlfriend and Jake, and the second time in front of the entire squad. In season five, Teddy has joined the bomb squad and tries unsuccessfully to steal Amy away from Jake on the day of their wedding.

• {{anchor|Adrian Pimento}}Jason Mantzoukas as Adrian Pimento, an emotionally unstable and volatile former detective who returned to the 99th Precinct after spending 12 years undercover in the organization of Jimmy "The Butcher" Figgis. He began dating Rosa in "Cheddar", and the two got engaged in "Paranoia", promptly before Pimento and the 99 were forced to fake his death. Pimento returns from hiding when Jimmy "The Butcher" Figgis is caught, but is refused his old job at the NYPD and becomes a Private Investigator. His relationship continued with Rosa, but she later breaks up with him in season five. He spends the next couple of months in Alaska before returning to Brooklyn to return as an insurance agent in "Gray Star Mutual", but is fired in the episode and starts working at a hand lotion store.

• {{anchor|Captain McGinley}}Michael G. Hagerty as Captain McGinley, the 99th Precinct's commanding officer before Raymond Holt, who was fired for his ineptitude and his permissive attitude toward the disruptive antics of Jake and his colleagues. McGinley later died in the episode "99" and the squad attended his funeral in Los Angeles.

• {{anchor|Madeline Wuntch}}Kyra Sedgwick as Madeline Wuntch, a callous and unethical NYPD deputy police chief who shares a deep mutual hostility with Captain Holt. Wuntch and Holt were once partners and friends, but they fell out after Holt rejected her sexual advances and Wuntch gained promotions for which Holt was passed over, resulting in Wuntch eventually becoming Holt's direct superior. Wuntch constantly goes out of her way to undermine the 99th Precinct, and appears to take great pleasure in its and Holt's failures; Holt, in turn, gleefully insults and belittles Wuntch every time their paths cross. In "The Chopper" and "Johnny and Dora", she culminates her victory over Holt when she makes him head of the NYPD Public Affairs Division, where she humiliates him by making him do menial jobs, although he is eventually transferred back to the 99 thanks to Jake.

• {{anchor|Marcus Marinovich}}Perry L. Brown as Marcus Marinovich, a judge at the New York Court of Appeals who sometimes oversees cases for the 99. He serves as judge when Peralta and Diaz are on trial in "Crime and Punishment".

• Will Hines as Carl Krum, the Kings County District Attorney who sometimes works with the 99 during court cases. He served as the attorney for the prosecution against Peralta and Diaz in "Crime and Punishment".

• {{anchor|C.J. Stentley}}Ken Marino as Captain Jason "C.J." Stentley, the Nine-Nine's temporary, under-qualified captain. Not wanting his ineptitude to be evident, he gives everyone everything they ask for until Amy eventually requests he start being more firm. This backfires after he rejects their request to go to Florida and assist Jake and Holt and he assigns them to the night shift. He is eventually removed from the Captain position after he is awarded for taking down a major drug dealer (that Jake and Holt primarily took care of) and demonstrates his lack of professionalism in front of a group of reporters. It's revealed that Holt called the reporters in to help the crew return to the day shift.

• {{anchor|Olivia Crawford}}Allison Tolman as Captain Olivia Crawford, a candidate for the Commissioner position Holt is also seeking. She holds the belief that precincts should be eliminated, creating a rivalry with Holt. However, she and Holt realize that their competition will split the votes and cause John Kelly to win. She eventually withdraws her candidacy as he was the only reason she was in the running; he publicly called out the selection committee for only nominating a woman for PR purposes, despite having no intention of actually considering her for the role.

• {{anchor|Lohank}}Matt Walsh as Detective Lohank, a night-shift worker for the 99th precinct who shares Det. Rosa Diaz's desk. Lohank is shown to have an unfortunate personal life; his wife is addicted to pain-killers, whilst he suffers from prostate cancer. He owns a summer cabin, dubbed "Stink Puddle Manor", which he lends to Jeffords, Peralta and Boyle in "Into the Woods".

• {{anchor|Kelly}}Phil Reeves as Commissioner John Kelly, the new Commissioner who won against Holt for the title. Kelly plans to implement a vigilant policing initiative into the NYPD, leading Holt to oppose him as Holt believes it would be regressive and result in more stop-and-frisks. Kelly retaliates by worsening the Nine-Nine's working conditions. Kelly's demeanor is a complete contrast to Holt's as he is always smiling but condescending.

Family and friends of main characters

• {{anchor|Hank}}Kevin Dorff as Hank, the bartender at Shaws Bar, the squad's favorite bar.

• {{anchor|Kevin Cozner}}Marc Evan Jackson as Kevin Cozner, Holt's husband and the Chair of Columbia University's Classics Department. He dislikes the NYPD due to their treatment of Holt and his homosexuality during his earlier years on the force, but thaws a little when Jake shows him how much the 99th respects and cares for Holt. Like his husband, Kevin is cold, sardonic, formal and unemotional, although he claims that Raymond is the "funny" one in their relationship, something that puzzles the detectives. Cozner develops a rapport with Holt's assistant Gina Linetti, referring to her by her first name (by contrast, he takes pains to always call Jake "Peralta"). He also learned a couple of self-defense techniques from his husband, and used it to rescue Holt and Jake from Seamus Murphy. The two own a Pembroke Welsh Corgi named Cheddar.

• {{anchor|Doug Judy}}Craig Robinson as Doug Judy aka "The Pontiac Bandit", an intelligent, happy-go-lucky thief and forger who exclusively steals Pontiac vehicles. Judy is an outgoing man with a talent for staying one step ahead of Peralta, who considers him his nemesis.

In the first three seasons, Judy would team up with Jake and one of his colleagues to capture another criminal associated with him and escaped before they could arrest him. In season four, Doug is given immunity for his past crimes after helping Jake and Holt capture his brother. In season five, he appears to have gone straight and has started selling cars to child celebrities. When a shady figure from his past shows up and threatens his mother, he gets Jake's help in taking him down, but escapes the cops and steals diamonds that nearly cost Jake his job (which he later returns).

Throughout the first 2 seasons, Jake is shown to have a minor obsession with her, hung up from loosing her to Eddie Fung at his bar mitzvah.
