With Dynasty in its fourth season, Diahann Carroll saw the success of prime time soap operas, and noted that while they had covered many issues like rape and homosexuality, they had yet to tackle racial integration.

"[1] Linda Evans, who played Krystle Carrington, said at the time, "I don't think the impact of her coming on the show will affect only Blacks.

[1] She said in 2011 that Dynasty producer Elaine Rich "liked the idea of [Dominique] being a bitch", and Carroll said to her, "I think the most important thing for us to remember is write for a white male, and you'll have it.

To circumvent any chance the storyline would leak to the press, a number of scenes were filmed to introduce Dominique, including alternative lines revealing that she was the mother of Kirby Anders (Kathleen Beller) or the ex-wife of Alexis' former husband, Cecil Colby (Lloyd Bochner).

Dominique's husband Brady Lloyd (Billy Dee Williams) arrives in Denver in the September 26, 1984 season premiere episode, "Disappearance."

Following Fallon's memorial service in "The Rescue", Dominique makes the shocking claim that she is the daughter of Blake's father Tom Carrington (Harry Andrews) and his longtime mistress, Laura Matthews, and offers proof (a letter found in an old trunk left in the care of Laura's sister Bessie), therefore making her Blake's half-sister.

A financially strapped Blake makes a business deal with the very wealthy Dominique: forty percent of Denver-Carrington in exchange for $70 million.

Dominique survives the wedding massacre, and rejects an offer by the rebel leader to remain in Moldavia to "entertain the troops and improve morale".

She encounters Jonathan Lake (Calvin Lockhart), a state department employee, who reminds Dominique that they met years ago in Paris.

Dominique is torn between the two men until she learns that Jonathan has aligned himself with Bart Fallmont (Kevin Conroy), a politician who is fighting the pipeline project.

Dominique travels frequently to Los Angeles, and hires Monica Colby (Tracy Scoggins) to help run her L.A.-based record company.

In episode 134, Dominique's daughter, Jackie (Troy Beyer) visits her mother and asks to remain in Denver instead of returning to finishing school in Lausanne, Switzerland.

[7] A May 2018 press release teased that the show would introduce Blake's half-sister Dominique Deveraux, Jeff and Monica Colby's mother, in season two.

"[13] Ahead of the season four premiere, Elaine Hendrix spoke about her off-screen friendship with Michele and their onscreen rivalry as Dominique and Alexis, "I don't mean to draw any direct parallels, because we're obviously so different, but it will probably be the closest to the original [dynamic] between Joan Collins and Diahann Carroll.

"[14] After the season three premiere, Justin Carreiro of The Young Folks wrote, "Dominique won't let anything get in her way, including her own children [...] She felt right at home walking into these people's lives ready to ruin their day.

"[15] In the 2018 season one episode "Trashy Little Tramp", Jeff and Monica's grandmother (L. Scott Caldwell) confesses that their mother, Millie, was fathered by Thomas Carrington (Bill Smitrovich), making her Blake's sister.

[16][17] Jeff (Sam Adegoke) leaves a message for his mother in the season two episode "A Champagne Mood",[18] and invites her to Atlanta for a reunion in "The Sight of You".

This revelation puts a strain on Dominique's relationships with her children in "The Sensational Blake Carrington Trial", and Monica and Vanessa leave for New York.

Dominique secures a deal for her reality show to be produced by ramping up publicity over the scandal surrounding her leaked sex tape with Michael.

In "That Unfortunate Dinner", Dominique visits her mother (Roxzane Mims) who reveals that Thomas Carrington left her a key to a safety deposit box.

In "Everything but Facing Reality", Jeff helps fund Dominique's fashion line after she passes on a lucrative deal in order to produce affordable clothing, which she showcases on the red carpet in "But I Don't Need Therapy".

In "A Good Marriage in Every Sense", Blake seeks out Dominique's help to secure the black community's vote for his senatorial campaign.

Dominique notices a decline in Jeff's health as he begins to act erratically, and his madness grows out of control in "Filled with Manipulations and Deceptions" once he is convinced that Brady is a spy.

Dominique finalizes her divorce from Brady in "That Holiday Spirit" after she and Jeff save him from her vengeful creditors, and she revels in Alexis' failure.

In "Mind Your Own Business", Fallon struggles to mediate Dominique's conflict with Alexis over a prime time slot on her shopping network.

Dominique is presented with an opportunity in "I'll Settle for a Prayer" to design costumes for the film adaptation of The Biggest Payday, and Michael recognizes how far she has come since their initial sex scandal.

Dominique shows up to support Cristal and promote her designs during Blake and Ben's bench trial in "There's No One Around to Watch You Drown", and she later receives confirmation that she won the NordicStar contest.

Dominique attends Michael's wedding in "Catch 22", revealed to be in a committed relationship with Kevin and set to open her first clothing store on Bleecker Street.

"[25] Contrary, Justin Carreiro of The Young Folks described Dominique as "a breath of fresh air," adding that, "Now that Alexis is gone, we needed another glamorous villain who is all about status, wealth, and seizing the Carrington glory."

"[15] Interest in Dominique's storyline was revived upon the debut of Elaine Hendrix as the new incarnation of Alexis, many fans anticipating the feud between the two characters.
