Chicago P.D. (TV series)

as Sergeant Henry "Hank" Voight, the enigmatic and often mercurial chief of the Chicago P.D.'s Intelligence Unit. Despite his brutal, tough exterior, he is loyal to the cops and detectives serving under him and highly "dedicated" to the victims of the crimes his unit investigates to the point of committing human rights violations, mainly torture, and not respecting the law. He is first introduced in Chicago Fire as a dirty cop who clashes with CFD Lieutenant Matthew Casey after Voight's son, Justin, causes an accident in which a teenager is paralyzed, and Casey, who was first on scene, had intended to testify that Justin was DUI. He is arrested by Det. Antonio Dawson for trying to have Casey silenced by force but is later released from prison and reinstated to the police force by Internal Affairs. As a result, many of Casey's colleagues dislike him, and Casey's superior Chief Boden has a love-hate working relationship with him. It is eventually revealed in the Chicago Fire episode "Let Her Go" that his dirty cop alter ego was part of an undercover operation to catch criminals and other dirty cops. Prior to taking command of Intelligence, Voight worked in the Gang Unit. His father Richard was a former CPD officer who was killed in the line of duty. Voight is a widower; his wife, Camille, died of cancer some years prior. His son, Justin, served in the Army and was killed in the last episode of season 3 while trying to help a friend. Voight took an interest in Erin Lindsay at 14 and raised her as his daughter.

Jason Beghe

as Senior Detective Antonio Dawson (seasons 1–6), an Intelligence Unit detective who previously arrested Voight for harassment and has since worked alongside him. Unlike Voight, he has limits on how far he will go to get criminals off the streets, as shown by the fact that he asks Halstead to stop Voight from killing anyone while on the hunt for Pulpo because he does not want it on his conscience. He and his ex-wife Laura have two children: Diego and Eva. He is the older brother of Chicago Fire character Gabriela "Gabby" Dawson. In season 4, he is offered a job at the State's Attorney's Office as Lead Investigator, which he accepts. After becoming disillusioned with the job, he returns to the unit in the first episode of season 5. In season 6, Antonio struggles with recovering from a shoulder injury and dependency on the oxycodone he is taking for the pain. After a dealer he owes kidnaps, beats, and rapes his daughter, Antonio, high on oxy, kills him in revenge. Though Voight and Ruzek manage to cover up the incident as self-defense, and Antonio successfully recovers in rehab, mayor-hopeful Superintendent Brian Kelton later gets the case reopened in order to take down the Intelligence Unit, and in the season finale, Antonio relapses after Ruzek is arrested after taking the blame for everything to protect him. In the season 7 premiere, it is revealed that Voight found Antonio and checked him into an off-the-books rehab clinic to get him clean again while also protecting his career. It was revealed several episodes later that Antonio resigned and moved to Puerto Rico to spend more time with his family.

She was in a relationship with her partner Jay Halstead from seasons 2 to 4.
