Main characters Athena Grant
Athena Grant (née Carter) (Angela Bassett) is an LAPD detective (formerly field sargeant), and mother of May and Harry from her first marriage to Michael Grant. Athena left her home in Florida for Los Angeles to become a police officer as a result of the failed investigation into the murder of her friend and neighbor Tanya Kingston (a murder she helps to solve 45 years later). She is extremely independent, preferring a one-person patrol unit to working with a partner (although she does work with detectives on certain cases) and is extremely tenacious when it comes to solving crimes or chasing down suspects (including the killer of her fiancé decades later after the murder weapon is recovered). However, she can be impetuous and has gone into dangerous situations without back-up (on one occasion getting ambushed and almost killed by a dangerous suspect). Athena and Michael divorce at the end of the first season, after being married for fourteen years. She begins dating Bobby Nash, marrying him at the end of the second season. Due to the traumas she has suffered in the past, she rarely shows her emotional side (except to Hen) but has begun allowing Bobby in (although at the beginning of Season 7, she has begun to worry that apart from the constant excitement and danger in both their jobs she and Bobby may not have enough in common to sustain their marriage).
At the end of season 9, Athena is caught in the crossfire of the criminal Castor family and the corrupt Detective Hooks. She is shot in the chest by Hooks and is placed into a medically induced coma, where she has visions of her former partner. Though she ultimately survives, she decides to pursue a change of pace in her career and becomes a detective.
Pepi Sonuga portrays a younger Athena during the flashback scenes of the season 3 episode "Athena Begins", and briefly reprises the role in seasons 8 and 9.
Evan Buckley
Evan "Buck" Buckley (Oliver Stark) is a firefighter at Station 118 and Maddie's younger brother. He joined the LAFD after a series of jobs in various parts of the country(the moniker Buck evolved in the fire academy where there were three other cadets named Evan). While he can be impetuous to the point of recklessness while in the field, he is dedicated to his job. Because of his dysfunctional relationship with his own parents, he sees and trusts Bobby as a father figure and the members of the 118 as his family. He convinced his sister Maddie to join the 9-1-1 Emergency Dispatch and introduced Abby's mother's former caretaker Carla to Eddie Diaz to help with Eddie's son Christopher. Buck was an uncontrollable womanizer at first (which nearly cost him his job in Season 1, since he was using LAFD property to facilitate his liaisons), but after meeting Abby he started looking for serious relationships. After Abby's departure, he reverted to "hit-and-run" relationships for a while, before dating multiple women - including TV reporter Taylor Kelly.
In the third season, Buck is not cleared for duty after the fire truck accident, so Eddie drops Chris off so he can babysit him. They spend the day at the boardwalk until a tsunami hits. Buck does his best to protect Christopher, as well as helping other civilians get to safety. When another wave hits, he and Chris get separated. Buck looks everywhere for him and eventually has to tell Eddie what happened. However, Chris was safe with a woman and she said he was asking for Buck. The next day, Eddie drops Chris off again with Buck, since he trusts him the most with his son. Buck works on getting back into the 118, but Bobby does not think it is safe due to his injuries. He ends up suing the department for his job back, which causes a divide between him and the rest of the 118. Eventually Bobby lets Buck come back, but he is on a tight leash.
In Season 6, he agrees to be a sperm donor for his friends Connor and Kameron, who are having fertility problems. During a dry thunderstorm in Season 6, he is struck by lightning which causes his heart to stop beating. However, he is successfully revived, and ends up gaining math skills due to this (was shown to not be his strongest subject in the past).
In season 7, he realizes he is bisexual, and begins dating former 118 firefighter Tommy Kinard, though they later break up after Buck asks Tommy to move in with him. It is later revealed in the same season what Tommy is insecure about the nature of Buck's relationship with Eddie Diaz.
In season 9, after Buck and Eddie attend the National Firefighting Games in Nashville, they are involved in a car accident in New Mexico orchestrated by waitress Bonnie and her ex-husband Earl. Though they both survive, Buck is abducted by Bonnie, who believes Buck to be a replacement for her brain-dead son. After Eddie rescues Buck, the stress of the kidnapping, Bobby's death, and his physical injuries lead Buck develop a opioid dependency after being previously being prescribed oxycodone for his injuries. After quitting cold turkey, he begins to suffer from a brutal withdrawal process. It gets to a point where, after being left alone in an ambulance, he considers stealing medication to ease his pain, though he ultimately decides not to. He later confesses his dependency to Chimney, who arranges for the 118 to care for Buck, so he is able to manage the rest of his withdrawal symptoms with his found family by his side. Later, he reunites with Connor and Kameron, and their son (and his biological son) Theo. When Connor and Kameron are killed in a car accident shortly after, he decides to become a foster father to Theo and welcomes him to his home.
Henrietta Wilson
Henrietta "Hen" Wilson (Aisha Hinds) is a firefighter & paramedic at Station 118. Originally a pharmaceutical representative, she left that job and joined the LAFD as a paramedic after saving her life coach with CPR. She was accepted at Station 118, but like Chimney, was met with prejudice and sexism from the captain and teammates. She became partners and close friends with Chimney due to their shared experiences of being minorities within the house. Hen had also met and befriended police sergeant, Athena Grant, who helped encourage her to stand up for herself within the firehouse. She was originally in an emotionally abusive relationship with Eva, who was a drug addict. Eva was then imprisoned, and Hen met Karen (via a blind date Chimney set up) and later married her. They have an adopted son named Denny, who is the biological son of Eva.
After Eva's release from prison, Hen cheated on Karen with her. This gave Eva a reason to try to get custody of Denny, claiming Hen's infidelity proved that her household was unfit for her son.
In Season 3, Hen decides to apply to medical school and is accepted but is unable to fully balance her hectic school schedule with her paramedic job and her family life, and fails a critical examination. She is allowed to return to medical school, but eventually quits in Season 6, preferring to remain a paramedic. In Bobby's absence, she is Interim Captain.
At the start of the seventh season, the 118 responded to a vehicular collision, where Hen was acting captain while Bobby was away. An intoxicated young man caused the crash and Hen offered medical treatment, but the man refused, leading him to die of his injuries. Hen and Karen later foster their second child, a young girl named Mara Driskell. In the beginning, Mara has trouble adjusting and acts out, which makes the couple almost consider removing her. But Hen ultimately decides to not give up on her and they find out both of Mara's parents died on the same night due to an overdose. After showing her they will not give up on her and they care, Mara starts enjoying her new home. Hen and Karen decide to adopt Mara, but their application is blocked and their fostering license is revoked. It is revealed that the man who refused medical treatment and later died ended up being the son of Councilwoman Olivia Ortiz, who was angered at Hen for letting her son die. In the eighth season, Hen is able to expose Ortiz for her corruption, allowing her and Karen to re-assume custody of Mara and have their foster license reinstated.
Howard Han
Howard "Chimney" Han (Kenneth Choi) is the Fire Captain at Station 118, and Maddie's husband. The reason why he is nicknamed "Chimney" and how he got the nickname is a closely guarded secret and to date has not been revealed. He grew up in the Los Angeles area with his mother while his father returned to South Korea, divorced Chimney's mother and remarried; as a result, their already strained relationship worsened. The elder Mr. Han openly expressed his disappointment in Chimney's chosen profession. After his mother's death, Chimney was raised by the Lee family (his mother and Mrs. Lee were best friends) and looks on them as his family. There, he developed a close bond with their son, Kevin Lee and both worked at a karaoke sushi bar the former managed. A fire burned down the building, but it gave both of them a new sense of passion and enter the fire academy together. They both passed the academy; Kevin was placed at Station 133 and Chimney to 118. Upon his arrival, Chimney was met with a prejudiced boss and was not allowed to go on calls, being forced to do grunt work. The other firefighters were also intolerant and would joke around at Chimney's expense. Eventually he met Eli Cobb, a paramedic, which led to Chimney deciding to become a firefighter-paramedic. During a building fire, both the 118 and 133 responded, but Kevin sacrifices himself to save a pregnant woman. At another call, Chimney correctly deduces there is a gas leak and gets Athena Grant to evacuate the area. Fellow firefighter Tommy Kinard was also trapped inside, but was able to be saved before the explosion, thus Chimney earning the firehouse's respect. He was also previously Karen Wilson's neighbor and friend, and the reason she and Hen got together; he had set up a fake blind date for them, and tricked Hen into coming to the bar under the pretense of drinks.
In the first season, Chimney gets into a car crash with a truck carrying rebars. One rebar goes through his head, but he miraculously survives. In the second season, he meets Buck's sister, Maddie, whom he takes a liking to and goes out on a few dates. He meets and befriends her abusive husband, Doug Kendall, although he is unaware of his true identity. One night when Chimney was coming over to Maddie's house, Doug gets through the gates and stabs him. This allowed Doug to kidnap Maddie.
In the third season, Chimney and Maddie's relationship continues to grow and they officially start going out. His younger half-brother, Albert, makes a surprise visit after he secretly left South Korea to escape their father, with whom he had been living for a while. At first, Chimney is cold towards him but after hashing things out, he starts embracing Albert as his brother and they live together for a while. At the end of the season, Maddie and Chimney find out she is pregnant and the baby is Chimney’s.
