The series features an extensive regular cast, including Scott Bakula as Dwayne Cassius Pride, Lucas Black as Christopher LaSalle, Zoe McLellan as Meredith Brody and Vanessa Ferlito as Tammy Gregorio.

Recurring actors, including Shanley Caswell as Laurel Pride, Rocky Carroll as Leon Vance, and Derek Webster as Raymond Isler, appear intermittently.

In "Chasing Ghosts" and "Le Carnaval de la Mort", it is revealed that Pride's father, Cassius (Stacy Keach), is incarcerated in the Gretna Correctional Facility.

[3] Pride joined the Naval Criminal Investigative Service in 1989, 2 years beforeNCIS's Leroy Jethro Gibbs; both were part of a group of NIS agents known as the "Fed Five" who gained fame for apprehending Spencer Hanlon, A.K.A.

Pride, still recovering from gunshot wounds sustained in "Checkmate", accepts a promotion to Special Agent-in-Charge of the NCIS Southeast Field Office, which has an area of responsibility that spans across the states of Georgia and Florida down to the Caribbean and into Central and South America.

Pride, similarly, contacted Director Vance to note how worried he was about Sebastian's abilities in the field, but also added that he believed he deserved a chance to prove himself.

Rita Devereaux (Chelsea Field) is a New Orleans Assistant District Attorney and a reservist in the U.S. Navy's Judge Advocate General Corps, holding the rank of Commander.

At the end of season 3, Rita accepts a job with the United States Department of Justice National Security Division and moves to Washington, D.C., but maintains a long-distance relationship with Pride.

Even in prison Cassius remains the semi-lovable con artist, trying to leverage his son into writing a letter of support for his annual parole hearings; even trying to use his granddaughter Laurel to work on Dwayne's sentiments.

Whenever Cassius does make parole, he stays in New Orleans for a while, but by the time of Season 5's "Tick Tock", he had been living a "good life" in "Evansville, Kentucky", in some kind of witness cover program, with armed federal agents protecting him; it was from here that he was kidnapped by Apollyon and held for ransom along with Dr. Loretta Wade.

In the Season 5 finale "The River Styx, Part II", an older Mena (Joanna Cassidy) appears in Pride's mind while he is being drugged in order to divulge some key information to the Apollyon leader Avery Walker (Tim Griffin).

Their marriage ultimately falls apart because Pride is married first to his job, which is dangerous, and the daily stress and worry on his wife Linda genuinely mirrors the family dynamics of many law enforcement and military personnel.

Sydney Halliday (Riann Steele) is an Army special operations soldier working her last duty station in South America, and she is suspected in a drug-infiltration murder scheme among military personnel, but is cleared by Pride, Sebastian and Gregorio in the Season 4 episode "Welcome to the Jungle."

In the trilogy of episodes that form the Season 4 finale, Sydney is recruited by Pride to be the muscle on his "off-books" clandestine team to take down AAG Eric Barlow and his deadly security tech Amelia Parsons.

Agent Naomi Parsons (Kate Beahan) is an Australian ADFIS Investigator seconded to New Orleans, and a romantic interest for Dwayne Pride, in the Season 2 episode "Foreign Affairs."

Parsons finally confesses to Pride that she was once a well-off lawyer whose pursuit of justice brought her into the investigative side of the law; now she's still "hard-charging", providing answers and comfort and closure to service members' families who have suffered the loss of a loved one.

Raymond Isler (Derek Webster) is the executive assistant director of the FBI National Security Branch and Agent Tammy Gregorio's direct superior.

In the closing episodes of Season 5, "The River Styx" Parts 1 & 2, Isler has traveled undercover to the disputed territory of South Ossetia in the Caucasus in pursuit of Avery Walker and Apollyon — the same criminals pursued by Pride and NCIS New Orleans.

He was arrested by Pride and removed from office at the end of season three because of the Clearwater case (a plot to flood part of New Orleans so Hamilton's company could build a new shipyard in the neighborhood).

On the job for years, Estes nevertheless becomes increasingly impressed with Dwayne Pride and his NCIS team, as he has opportunity to see them "do more with less", and actually get good results while staying within the legal procedures required.

Karen Izzo (Sharon Conley) is an Assistant United States Attorney assigned to investigate Pride's team during NCIS: New Orleans's third season.

She shows up in a number of episodes, mostly as an antagonist in the local legal structure, blocking the NCIS team from doing what they consider to be their jobs, and often appearing to be an apparatchik of either Mayor Hamilton or some other political entity.

He is eventually revealed to be the main Washington D.C. official who has been gunning for Pride and his team for a long time, and who was the real puppet-master behind Mayor Hamilton and his business aspirations.

Pride's team just barely get away, but are spotted and then legally pursued by Barlow's henchmen, including his ultra-dangerous tech chief Amelia Parsons, whose computer station had been breached while she was drawn away from it by Dr. Wade.

Barlow's tech people faked photos of Pride driving the truck with explosives in it, and a crooked NOPD leader — Deputy Chief Cedric Gossett (Lou Diamond Phillips) — pretending to avenge Captain Estes murder, turns out to be Barlow's own puppet candidate for mayor, and he kidnaps Pride onto the Police boat from which a rocket attack will be launched against Mayor Taylor's car.

John Stone (Maury Sterling) is Mayor Hamilton's new security chief, appearing in Season 3 episodes "Knockout," "Down the Rabbit Hole," and "Poetic Justice".

It is discovered that she was, in reality, the wife and widow of former mayor Hamilton's security chief John Stone, and besides Barlow's anti-NCIS plans, she has her own revenge to serve to Pride, who killed her husband in self-defense.

Ameila is tough as nails, ruthless, adept at evading capture, and possesses both martial arts, weapons, and tech skills to infiltrate, harass and pursue targets.

Walker was a mercenary and independent security contractor in the Middle East, who then started working for a Russian oligarch, and ended up being a top operative in the intelligence crime syndicate Apollyon, eventually running that too — with ties to foreign terrorist organizations.

The succeeding episode "Vindicta" reveals that NSA analyst Philip Sinclair (Matthew Rauch) is the head of Apollyon, but made it look like Walker ran the hostage op from prison.
