Sergeant II Daniel "Hondo" Harrelson Jr. is a native of South Los Angeles. Hondo was born in 1974 to Daniel Harrelson Sr., and Charice Harrelson; he also has a sister, Winnie. When Hondo was a kid, his father left the family after falling in love with another woman and moved to Oakland, California, where he eventually had another daughter, Briana. Hondo and his dad remained in touch, and Hondo lived with him during the summer in his teenage years.

As a kid, Hondo and two of his best friends, Leroy and Darryl, were part of a gang, but after Darryl's death, Hondo went to Crenshaw High School and eventually joined the force.

After high school, Hondo enlisted in the United States Marine Corps; he served four years (1994 to 1998) with the 1st Battalion, 9th Marines out of Marine Corps Base Camp Pendleton and deployed to Somalia. After his enlistment ended, Hondo joined the Los Angeles Police Department.

Hondo began his Los Angeles Police Department (LAPD) career as a patrol officer with the 77th Street Area. He served as a patrol officer for six years before becoming a member of S.W.A.T. By 2016, he was serving as a Senior Lead Officer on Sergeant Buck Spivey's S.W.A.T. Team. Hondo maintains a good relationship with those in the neighborhood, leading to residents often giving him information on cases.

In 2017, Hondo was unexpectedly promoted to Team Leader after Buck was fired for accidentally shooting an unarmed black teenager during a shootout in a blatant attempt to ease the tensions between the community and the LAPD.

Four months before the series, Hondo began a surreptitious romantic relationship with Captain Jessica Cortez, which, while frowned upon, was not expressly forbidden by LAPD policy; however, after his promotion to Team Leader (which put him directly under her command), the two struggle to keep their relationship secret. Hondo ultimately ends the relationship after they are caught by Commissioner Michael Plank to protect her career. He later starts a relationship with Nia Wells, a Los Angeles County Deputy District Attorney and recent divorcée. The relationship ends due to his anger after an encounter with a racist Arizona Department of Public Safety officer and the inability to prosecute the man who drugged and attempted to rape his sister.

In the third season episode "Track", when Hondo pursues of an armed robbery suspect that leads to a vehicle collision, he meets a woman named Nichelle when he aids a man in an accident. Afterward, Hondo starts dating Nichelle until they break up at the end of the season, when Hondo realizes they are on two different paths in life. They remain friends during the fourth season, and towards the end of the season, they restart their relationship after realizing how happy they make each other. In Season 5, Hondo learns that Nichelle is pregnant with their first child. In the sixth season, at the end of the episode "Whoa Black Betty", 20 Squad reveals to Hondo and Nichelle that they're having a girl. In "Invisible", after failing to secure a good foster family for Darryl Henderson, the teenage son of his friend Leroy, Hondo applies to become Darryl's official foster father.

Hondo becomes disillusioned with the LAPD after they fail to terminate a group of racist police officers despite Deacon having a recording proving their guilt. Disgusted with the LAPD's lack of action, Hondo speaks to the Los Angeles Times about the group, risking his career. Although the racist officers are finally terminated, Hondo is demoted as team leader for going to the press. Hondo then leaves Los Angeles to relocate to a Mexican village to reevaluate his life and career. He helps a family being targeted by an Irish international criminal named Arthur Novak and his son AJ. The two had kidnapped a young girl named Delfina, who is rescued by Hondo and a local cop named Charro. Delfina is brought home to her family, and Hondo returns to Los Angeles to rejoin S.W.A.T. and 20 Squad. With Hondo back on S.W.A.T. and 20 Squad reinstated, new member Rodrigo Sanchez is selected to lead 20 Squad until Luca tells Hondo that the police commissioner hired Sanchez to get Hondo to quit. This plot failed when Luca and Deacon pushed Sanchez into taking a private security job. Hondo was reinstated as leader after Sanchez departed.

Hondo once dated Elle Trask, an FBI Agent. He later dated Nia Wells, an Assistant District Attorney, but later broke up when he had threatened to go after a man, he accused of drugging his younger half-sister, Briana, at a nightclub to possibly take advantage of her. He then went on to dating Nichelle when they first cross paths helping an injured man following a pursuit of armed robbery suspects that Hondo was in. At the end of the fifth season, Hondo learns that Nichelle is pregnant with their first child. She gives birth to their daughter Vivienne in the sixth season and the two marry in-between seasons six and seven.

As a S.W.A.T. officer, Hondo drives a 2015 Dodge Charger Pursuit and carries a Kimber Custom TLE II in .45 ACP as his duty weapon.

His call sign is 20-David.

Ultimately, in the season one finale, Street strains his relationship with the team to deal with another crisis involving his mother, which leads to Hondo kicking him off S.W.A.T.

In "Crews", Chris is asked by Officer Erika Rogers, a S.W.A.T. candidate, to help her prepare for joining the teams. Although she declines to help directly – believing that the only woman in S.W.A.T. helping the only current female S.W.A.T. candidate could ultimately hurt both of them – she does arrange for Street to help her on the course and Luca (who is a member of the S.W.A.T. selection board) to ensure Officer Rogers gets a fair shake from the members.
