### Maggie Bell

Special Agent Maggie Bell is an FBI agent based at the New York City field office. In the pilot, it is established that she comes from Indiana and has been in New York City for three years. Maggie is a seasoned Investigator who is in charge of the team while out in the field. A former police officer, she was recommended to join the FBI after working with them on a kidnapping case back in Indiana. She is partnered with O.A., who joined the NYC field office after an undercover operation.
Maggie was happily married to reporter Jason Bell, who died in a car accident. Throughout season 1, she is seen secretly looking at photos and videos of Jason on her phone. She generally refused to talk about him to her colleagues, although O.A. seems to have known about her being a widow from the beginning. In the episode "Exposed", she finally confesses to O.A. that she has been having a hard time coping with Jason's death and has yet to clear out his closet. While investigating the murder of an investigative journalist in that episode, the team realize they are dealing with a professional assassin who has left a trail of bodies spanning several states and Maggie recognizes the man's face in a video she took of Jason, leading to her suspicions that the car accident Jason died in was engineered. She gets closure in the season 1 finale when she and her team apprehend the real perpetrator.

### Omar Adom "OA" Zidan

Special Agent Omar Adom "OA" Zidan born some point in 1987 is an FBI agent based at the New York City field office. A native of New York City, he returned to his hometown after a stint undercover tracking down jihadist terrorists. He is a practicing Muslim and is of Egyptian heritage, having grown up in Astoria, Queens where there is a sizable Egyptian-American community. While he proudly identifies with his religion and heritage, he prefers to be called "American" rather than "Egyptian". He has a particular distaste for right-wing extremists, having seen his faith utilized for all the wrong reasons during his previous undercover assignment and endured bullying and Islamophobic remarks in school after the September 11 attacks.
OA's encyclopedic knowledge of the Quran and fluency in speaking and reading Arabic has proven useful at times. According to Dana he is the NYC field office's only Arabic-speaking agent with undercover experience.
Little is known about OA’s family as he is reticent about his personal life. It was mentioned in season 1 that his father had died a decade ago, leading to him acting as a father figure to his younger sisters and having the tendency to be overprotective of them. In season 2, he began dating lawyer Mona Nazari, whom he had crossed paths with several times while she was with the Southern District of New York.
OA graduated from the United States Military Academy and left the Army with the rank of Captain. His military background has proven useful as he is familiar with various types of explosives, ballistics and firearms and their uses. He served on two tours in Iraq on Operation Iraqi Freedom with the 75th Ranger Regiment.
Series creator Dick Wolf was initially casting a Latino for the ambiguously-named role of "OA” but Zaki's audition tape impressed him enough to change the character to mirror Zaki's own ethnicity and background. Like the character, Zaki is a Muslim Egyptian-American who speaks Arabic and still has relatives in Egypt. Zaki has stated that Wolf and his writing team encouraged him to give input into his character to provide more authenticity.

### Jubal Valentine

Assistant Special Agent in Charge (ASAC) Jubal Valentine is the second-in-command of the New York field office. He mostly coordinates the activities and movements of analysts and field agents from the Joint Operations Command (JOC) room in 26 Fed with many of the techs there either calling him by his first name or "Boss" and "Sir". Jubal usually stays behind at the field office to run operations, even briefing the team on their latest case while also giving information to the field agents and motivating the techs at the JOC to find information regarding a current case while also dispatching the field agents to locations concerning a potential lead via an earpiece he wears but he has been out in the field several times to assist with undercover stings. and operations while even participating in a raid and hostage negotiations. He trusts his agents implicitly and gives them the benefit of the doubt that they will rely on their training and good judgement.
Jubal's father worked for the United States Embassy in Moscow during the 1980s with Jubal living there from the ages of 12 to 14, presumably during 1986 to 1988.
Jubal is also a recovering alcoholic but was completely sober for years, often attending Alcoholic Anonymous meetings. As revealed in the FBI Season 3 episode, "Unreasonable Doubt", when his girlfriend at the time, Rina Trenholm told him she didn't want to be his mistress with Jubal also reluctant to tell his wife about her, the two broke up. This prompted Jubal to get wasted that night and ended with him blacking out. Upon awakening the next morning, Jubal discovered that he was in his car in his driveway, behind the wheel, unable to remember how he'd even gotten there. He also found a huge dent on the car along with a lot of blood. Due to the fact no hit and runs had been reported, he came to suspect that it had been an animal and this incident was what prompted him to begin AA meetings and presumably get sober. Jubal remained sober for nearly ten years up until the FBI Season 5 episode, "Breakdown" where following a medical crisis concerning his son, Tyler, he temporarily relapsed, drinking once again although he later stopped and was seen going to an A.A. meeting.
He has even assisted others in fighting their own addictions and currently serves as a sponsor to Morris Kalu. When Kalu was taken hostage while working as an undercover informant to stop drugs from hitting the streets of New York in the FBI Season 1 episode, "Conflict of Interest", Jubal saved Kalu's life by shooting dead Tayo, the man holding Kalu hostage.
In the aftermath of 9/11 in 2001, Jubal, already an agent with the FBI was assigned to a multi-agency task force that saw him working alongside the NYPD which was revealed in the Season 5 episode, "Sins of the Past". During the FBI Season 1 episode, "Prey", it's revealed he also worked in Vice for an unknown period of time and in the Season 2 episode, "An Imperfect Science", was previously a member of the Threat Response Squad.
Jubal is trained in undercover operations which he participates in during "Prey", "Fathers and Sons" and "Heroes". He can also beat a polygraph which is shown in the FBI Season 1 episode, "Identity Crisis". In addition, he's also a highly skilled crisis negotiator which is seen in "Safe Room", "Fathers and Sons", "Grief" and "Hero's Journey".
He met Jess LaCroix, the agent in charge of the FBI Fugitive Task Force sometime in 2012, the two men working on the Haynes Spree Killer case with Jess helping Jubal with his alcoholic problems. When Jess's wife, Angelyne died in 2016, Jubal returned the help.
In 2014, while assigned to the FBI's Boston Field office, Jubal also worked on a case with Stuart Scola and the two reunited in September 2019 when Scola was transferred to the New York field office.
When Jubal and Trenholm reunited in Spring 2021 during a case concerning drug cartel boss Antonio Vargas, they secretly began a relationship once the case had ended with the relationship continuing up until her death in January 2022 with it being revealed that Vargas had arranged for Trenholm's death in revenge for the murders of his own wife and young son who were killed and hung on a bridge in Mexico.
Like the main field agents assigned to the FBI New York field office, Jubal carries a Glock 19 as his main sidearm but unlike all the other agents and techs seen at the JOC, Jubal keeps his weapon on him at all times in a holster located on his right hip, presumably due to the fact that he could be sent out into the field from the JOC at any given moment.
Jubal is divorced but he and his ex-wife Samantha are on friendly terms and share custody of their two children, Tyler and Abigail although she has physical custody of them. As part of their divorce agreement, she cannot move the children without his consent. This posed a conundrum for him when her new boyfriend got a job in Westchester County and she came to him asking for his consent to move the children out of New York City to the suburbs. He finally agrees after going to check out the new house and neighborhood for himself.
Along with Zeeko Zaki (OA Zidan), Sisto had appeared in every single episode of the FBI series since the FBI series premiere episode, "Pilot" up until the FBI season 7 episode, "Perfect" which is the first episode he has not appeared in.

### Kristen Chazal

Kristen Chazal is an FBI technical analyst and later field agent based at the FBI field office in New York City.
In FBI Season 1, she serves as a technical analyst, often reporting her findings to the field agents and Special Agents in Charge Ellen Solberg, Dana Mosier and Isobel Castille as well as Assistant Special Agent in Charge Jubal Valentine although midway through the season, she confides in FBI agent Maggie Bell that she wishes to become a field agent.
In FBI Season 2, Kristen becomes a field agent with her new partner being FBI Special Agent Stuart Scola although she usually returns to the Joint Operations Command or JOC to search for information on the team's latest case but in the episode, "Ties That Bind", Kristen finds her confidence being shaken when she makes a mistake during field training which results in Scola being shot with a paintball, an incident that has the instructor berating her over. Near the end of the episode, Kristen joins the team in attempting to arrest Jordan Cameron but is left badly injured when Jordan stabs her in the throat, Maggie tending to her while Jordan is shot dead by Scola and OA.
As Kristen in treated in "Fallout", she is temporarily replaced by agent Emily Ryder and even though Kristen makes a full recovery, ultimately being discharged in "Hard Decisions" while expressing her intent to return to the field, this has her teammates doubtful.
Eventually, during "Legacy", Jubal allows Kristen to return to the field and she helps her colleagues arrest the men of terrorist Sulaiman Mansor while OA personally shoots Mansor dead, Mansor having disguised himself as a military police officer and secretly infiltrated West Point so that he could murder General Carson, the man responsible for signing off on the strike that killed Mansor's family.
In the FBI Season 3 premiere episode, "Never Trust a Stranger", a conversation between Jubal and Castille reveals that Jubal received a text from Kristen, informing him she had moved to Dallas, Texas and subsequently joined the FBI field office there with former NYPD officer Tiffany Wallace later permanently replacing Kristen as Scola's partner.

### Ellen Solberg

Ellen Solberg is the Special Agent in Charge of the FBI New York field office.
Appearing only in the FBI Season 1 series premiere episode, "Pilot", she oversees the investigation into the blast that destroyed an apartment building in downtown New York and although the investigation lasts for two days, her field agents successfully apprehend Robert Lawrence, a white supremacist responsible for the attack.
After the case has been solved, she receives a phone from ASAC Jubal Valentine, informing her of a kidnapping in The Battery (Manhattan).
Due to her actress, Connie Nielsen being unable to commit the series after the pilot episode, Solberg was written out of the series and replaced by Dana Mosier (Sela Ward) who became the new Special Agent in Charge while following Mosier's retirement, she was replaced by Isobel Castille (Alana De La Garza) who in turn replaced Mosier as the new SAC.

### Dana Mosier

Dana Mosier is a Special Agent in Charge of the FBI New York field office.
Prior to joining the New York field office, she was with the FBI's Behavioral Analysis Unit where she profiled serial killers, a skill she often uses during her time as SAC at the New York field office to give herself and the team an insight into the psychological mindset of a criminal. She is also married and has an unnamed daughter which was revealed during the FBI Season 1 episode, "Green Birds".
Mosier retires at the end of FBI Season 1 and is subsequently replaced by Isobel Castille who becomes the new Special Agent in Charge of the FBI's New York field office.

### Isobel Castille

Isobel Castille is the current Special Agent in Charge of the FBI New York Field office, having been promoted to the position sometime after the retirement of her predecessor, Dana Mosier with Isobel's tenure as SAC of the New York Field office beginning sometime around September 2019.
Previously an Assistant Special Agent in Charge and a Supervisor of the Fugitive Squad, she also attended and graduated from West Point while even working a brief stint in Silicon Valley.
She worked in the New York field office with Special Agent Jake Reed which was her first assignment, Isobel and Reed being partnered together with one of their first cases being the Collier abduction case that occurred in Staten Island. She and Reed had a romantic relationship at the time but presumably broke up.
In 2012, assigned to the Alabama field office, she was one of the first responders at the white supremacist bombing of a church that saw many fatalities including three children, something that still haunts her as revealed in the Season 2 episode, "Hard Decisions".
She was also possibly in the Drugs Division and good friends with Special Agent Kyle Miller who was murdered at the hands of Antonio Vargas, the head of the Durango cartel in 2013.
Isobel has a strained relationship with her father, Robert who is General Counsel of the Legal Department of CMR Hotels.
She is fluent in Spanish and can also read it, often translating it for her FBI colleagues.

### Stuart Scola

Stuart Scola is a Special Agent assigned to the FBI's New York Field office and also the current field partner of fellow FBI agent Tiffany Wallace. The character was introduced at the beginning of season 2.
A native of New York City and graduate of Princeton University, Scola is the middle of three children and has an older brother, Douglas, and a younger sister, Alexander. He worked as a stockbroker at Goldman Sachs for seven years before joining the FBI. The death of his brother during the September 11 attacks added to his disillusionment and prompted his decision to leave the corporate world.
Scola returned to his hometown after a stint at the Boston field office, where he first met Jubal. It was revealed on FBI: Most Wanted that he knew Sheryll Barnes from Quantico. His first partner was newly-minted Special Agent Kristen Chazal. Their partnership got off on a nervous start as she had no field experience and Scola often had to take the lead. Kristen later moved to Texas and he was partnered with fellow New York City native Tiffany Wallace, who had transferred from the Atlanta office.
During season 4, Scola first meets Nina Chase, who was brought in to cover for Maggie while the latter was recovering from Sarin gas poisoning. Tiffany was partnered with O.A. instead, much to Scola's annoyance. Scola eventually has a one night stand with Chase after a difficult case and later finds out he knocked up Chase in the process.
Scola presumably pursued a relationship with Nina off-screen and are a couple by season 5. At the end of the season finale, the 100th episode, Scola reveals that Nina had given birth to a son, named Douglas after his older brother.

### Tiffany Wallace

Tiffany Wallace is an FBI Special Agent assigned to the New York Field Office and also the field partner of fellow FBI Special Agent Stuart Scola.
Raised in Bed Stuy or Bedford–Stuyvesant, Brooklyn, she spent six years with the New York Police Department, specifically Narcotics and fell in love with becoming a federal agent while working on a joint task force.
Upon becoming an FBI agent, she spent two years in Atlanta before transferring to New York.
