Carrington family

As Dynasty begins in 1981, Carrington heirs Steven (Al Corley) and Fallon (Pamela Sue Martin) return to Denver to attend the wedding of their father, powerful oil tycoon Blake Carrington (John Forsythe), to his former secretary, Krystle (Linda Evans). The Carrington family dynamic is soon established; thoughtful and sensitive Steven resists his father's pressure to step into his role as future leader of Blake's empire, while his spoiled sister Fallon, better suited to follow in Blake's footsteps, is underestimated by and considered little more than a trophy to Blake. Steven befriends Krystle, who is adjusting to life at the mansion despite chilly receptions from Fallon and the Carrington majordomo, Joseph Anders (Lee Bergere).

Blake's ex-wife Alexis (Joan Collins) appears in the second season and soon stirs up trouble for the family. In 1982, their infant grandson L.B. Colby, the son of Fallon and Jeff Colby (John James) is kidnapped. Former spouses Blake and Alexis make a televised plea that he be returned, and Alexis confesses a dark secret from their past: their firstborn son, Adam (Gordon Thomson), had been kidnapped as a baby and never recovered. Traumatized by the event, they had hidden his existence from their subsequent children Fallon and Steven. Meanwhile, in Billings, Montana, an old woman named Kate Torrance tearfully tells her grandson Michael that he is really the Carrington heir. Armed with items from Adam Carrington's baby carriage, lawyer "Michael" comes to Denver and is eventually accepted as a Carrington, but his selfishness, greed and ambition put him at odds with all of his relatives at one time or another.

Steven leaves town that year and is presumed dead in an oil rig explosion in 1982; he turns up alive and returns (portrayed by Jack Coleman) in 1983. Fallon leaves town in 1984 and is also later presumed dead in a plane crash. At the same time, chanteuse Dominique Deveraux (Diahann Carroll) comes to Denver and soon makes a shocking claim: she is the daughter of Blake's father Tom Carrington (Harry Andrews) and his longtime mistress. Later in 1984 a young woman named Amanda Bedford (Catherine Oxenberg) appears on Alexis's doorstep; she is Alexis's youngest daughter,[lower-alpha 1] and it is eventually revealed that Blake is her father. Blake and Krystle also have a daughter, Krystina (Jessica Player), in 1984. Fallon reappears in 1985 (portrayed by Emma Samms).

Alexis brings Blake's vengeful, estranged brother Ben (Christopher Cazenove) to town in 1986 to help her destroy Blake, and Ben's daughter Leslie (Terri Garber) soon follows in 1987. Ben leaves town that year after reconciling with Blake, and Leslie having reconciled with Ben follows suit in 1988 after a failed romance with Clay Fallmont (Ted McGinley), who is possibly also Ben's child.

In 2017, wealthy siblings Steven (James Mackay) and Fallon Carrington (Elizabeth Gillies) arrive in Atlanta to meet their father's fiancée, Cristal Flores (Nathalie Kelley). Fallon and Cristal set themselves as rivals for Blake's attention, but over time they find common ground over their frustration with his machinations. In the 2018 episode "I Answer to No Man", Blake (Grant Show) reveals to Cristal that he and his first wife had another son, Adam, who was kidnapped at six months old and never returned. Blake's ex-wife Alexis (Nicollette Sheridan), Steven and Fallon's mother, reappears in the "Poor Little Rich Girl" after an extended exile. Alexis tells Steven about Adam, and Steven eventually finds his brother in El Paso, living under the name Hank Sullivan (Brent Antonello). Blake welcomes Adam back in "Trashy Little Tramp", not knowing that Hank is actually Alexis' lover with whom she is conspiring to amass enough Carrington Atlantic shares to seize control of the company. At the same time, Jeff (Sam Adegoke) and Monica Colby (Wakeema Hollis) learn from their grandmother—the former secretary of Blake's father, Thomas Carrington (Bill Smitrovich)—that their mother, Millie, was fathered by Thomas. Jeff and Monica reveal their Carrington heritage in "Dead Scratch"—though Blake is already aware of his half-sister—and declare their intention to force a sale of Carrington Atlantic.

In season two, Blake falls in love with Cristal Jennings (Ana Brenda Contreras). Fallon visits her cousin Juliette Carrington (Mathilde Warnier), the French daughter of Blake's disinherited brother Benjamin. Steven is revealed to be the son of Alexis and Anders (Alan Dale) in "The Butler Did It". The real Adam (Sam Underwood) also reappears, and is immediately welcomed into the family by Blake, though Fallon is wary of him. Blake's half-sister and Jeff and Monica's mother, now going by the name Dominique Deveraux (Michael Michele), appears in "New Lady in Town".

Blake marries Cristal (now Daniella Alonso) in season three.
