Sergeant II Daniel "Hondo" Harrelson Jr is a native of South Los Angeles, Daniel Harrelson was born to Daniel Harrelson, Sr. and Charice Harrelson; he also has a sister, Winnie. When he 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, going up to live with him during the summers of his teenage years.

As a kid, Hondo and two of his best friends Leroy (Michael Beach) and Darryl ran with a gang, but after Darryl's death, Hondo went to high school (graduating from 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 selected not to re-up and instead joined the Los Angeles Police Department.

Hondo began his LAPD career as a patrol officer with the 77th Street Area. He served as a patrolman for six years before becoming a member of SWAT. By 2016, he was serving as a Senior Lead Officer on Sergeant Buck Spivey's (Louis Ferreira) SWAT Team. He knows everyone in the neighborhood and treats them all with respect, and they usually give him information pertinent to his cases when he asks for it in return.

In 2017, Hondo was unexpectedly promoted to Team Leader after Buck was fired for accidentally shooting an unarmed black teenager during a shootout over senior team member Sergeant Deacon Kay (Jay Harrington) in a blatant attempt to ease the tensions between the community and the LAPD.

Four months prior to the series, Hondo began a surreptitious romantic relationship with Captain Jessica Cortez (Stephanie Sigman), 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 struggled to keep their relationship secret. Hondo ultimately broke up with her after they were caught by Commissioner Michael Plank (Peter Facinelli) in order to protect her career. He later started a relationship with Nia Wells (Nikiva Dionne), a Los Angeles County Deputy District Attorney and recent divorcée. The relationship ended 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 "Invisible", after failing to secure a good foster family for Darryl Henderson, the teenage son of his friend Leroy, Hondo decided to apply to become Darryl's official foster father.

Overtime, Hondo started becoming disillusioned with the LAPD after they failed to terminate a group of racist police officers despite Deacon handing a recording proving their guilt. Disgusted with the LAPD’s lack of action, Hondo went to the LA Times and revealed everything at great risk to his career. Although the racist officers were finally terminated, Hondo was demoted as team leader for going to the press. However, he was reinstated as leader again in season five's "Crisis Actor", after Sanchez departed as leader of 20-Squad.

As a SWAT 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.
