Lt. Grace Billets
Lt. Grace Billets is the commanding officer of the LAPD Hollywood Division's detective bureau and has been since 1994. Known for her commanding presence and managerial style of running the bureau, Grace gets along with just about everyone and, despite its unorthodox nature, Grace's style goes hand-in-hand with leading her superiors to successfully solving cases.

Honey 'Money' Chandler
Honey 'Money' Chandler is a defense attorney who is introduced in Bosch's first season, thus appearing in every episode of the seven-season original series. Known for her austere and stern presence, Honey initially starts the series off as an antagonist to Bosch, since her profession dictates that she defend many people Bosch knows is guilty. However, after experiencing some of the corruption in the justice system firsthand, Honey reconsiders her stance on law and on Bosch. Appearing in every Bosch: Legacy episode, Honey will likely be in season 3 as well.

Maddie Bosch
Maddie Bosch is Bosch's daughter and is seen growing from a teenager to a young woman throughout Bosch's seven seasons. By the events of Bosch: Legacy, Maddie is seen following in her father's footsteps as she is now a Los Angeles Police Department Police Officer learning the ropes. Despite getting off to a rocky start, Maddie gradually becomes more competent as a police officer thanks to Rico and Reina, even starting a romantic relationship with Rico in the process. Although season 2 of Bosch: Legacy ends on a cliffhanger, Maddie will be back in Bosch: Legacy season 3 as her character is essential to the story.

Sgt. John 'Mank' Mankiewics
One of Bosch's older characters, Sgt. John 'Mank' Mankiewics is a desk sergeant working for the LAPD, and he once worked closely with Bosch back in the day. Currently, Mank has taken it upon himself to look after his former partner's daughter, Maddie, as a show of good faith, since the two former partners got along incredibly well despite their differences in approach to doing their jobs. Given his relationship with the Bosch's, he'll likely return for Bosch: Legacy season 3.

Jerry Edgar
Jerry Edgar is Bosch's partner, thus appearing in every episode of the original series in some capacity or another. Known for his good taste in suits, sarcastic delivery, and intense presence, Jerry is nearly the opposite of Bosch in many ways. Despite this, he's loyal and always ready to do what's necessary to help Bosch. Although he doesn't play a major role in the Bosch: Legacy episode, 'Chain of Authenticity,' it set him up as a character who will once again help Bosch - this time with investigating Maddie's disappearance. Considering the nature of the stakes, Jerry will likely be in Bosch: Legacy season 3 in a more substantial role.

Rico Perez
Introduced to audiences in Bosch: Legacy's first season, Rico Perez is a fellow LAPD Police Officer who works alongside Bosch's daughter, Maddie, and their partner Paulina Calderon. Known for his big brother-like energy and resourcefulness out on the field, Rico acts in something of a mentorship capacity to Maddie, helping her quickly learn the ropes to becoming a successful police officer within a relatively brief amount of time. In addition to the two quickly getting along, their professional relationship eventually develops into a romantic one as the two grow closer. Rico's energy and chemistry justify his return in Bosch: Legacy season 3.

Robert 'Crate' Moore
Never seen without his partner Barrel Johnson, Robert 'Crate' Moore is one half of the comedic duo prominently featured throughout Bosch and briefly appearing in Bosch: Legacy's first two seasons. Considering that Bosch and Bosch: Legacy are police procedurals, the subjects that both shows cover tend to veer off into the darker side of things, but Crate and Barrel help keep things light. Nevertheless, Crate and Barrel are competent lawmen as seen in the Bosch: Legacy episode, 'Horseshoes and Hand Grenades,' when Bosch recruits them to conduct surveillance. Given their resourcefulness and humor, they should be in Bosch: Legacy's third season.

Barrel Johnson
Also appearing prominently in Bosch is the older Barrel Johnson, an equally hilarious Investigator with the Los Angeles Police Department's Hollywood Division. Perpetually seen with his partner Crate, Barrel is just as intelligent as he is funny, often coming up with solutions to Bosch's problems despite his jovial personality. On account of assisting Bosch in the Bosch: Legacy episode 'Horseshoes and Hand Grenades,' Bosch warns the duo to watch their backs as the FBI might investigate them. However, Crate and Barrel reveal that they're retired, thus reassuring Bosch. Despite their retirement, Crate and Barrel's return in some capacity would be a welcome addition to Bosch: Legacy season 3.

Stephen A. Chang as Maurice Bassi
Introduced at the beginning of Bosch: Legacy, Maurice Bassi is a main character and the show's technical consultant who typically assists both Honey Chandler and Harry Bosch. Maurice is renowned for his playfully antagonistic role that he plays with Bosch, considering Bosch's misunderstanding and unwillingness to learn more about technology. This typically prompts Maurice to make a quip about the character, thus resulting in hilarious back-and-forth banter. However, despite their playful rivalry, Maurice and Bosch develop a mutual respect for one another after discovering their shared love of jazz music. Amiable and resourceful, Maurice can continue to be an asset in Bosch: Legacy's third season.
