Dex Dexter remained on the series until its final episode in 1989.

In 2022, Pej Vahdat was cast as Dex for the fifth season of the CW reboot series Dynasty.

Original series
Michael Nader first appeared as Farnsworth "Dex" Dexter in season four of Dynasty in 1983. The character was soon paired with Alexis Colby (Joan Collins),  and Nader remained on the series until its cancellation in 1989. Dex did not appear in the 1991 miniseries Dynasty: The Reunion.

Jon-Erik Hexum, who had previously starred opposite Collins in a film, was one of the five actors under final consideration for the role. Nader credited his chemistry with Collins with getting him the part. Collins said of Nader, "He's a very romantic leading man and he has a certain sinister edge." People noted in 1985 that Dex "was conceived as a minor and transitional character", but thanks to Nader, he "has turned into an unexpectedly popular one."

In 1985, Joe Klein of New York described Dex as a "multibillionaire-guerrilla-playboy-entrepreneur".

In "How Did the Board Meeting Go?", Amanda Carrington (Eliza Bennett) realizes a drone that flies by her mother Alexis Colby's (Elaine Hendrix) penthouse nightly could have photographed the fatal fall of blackmailer Dr. Larson from the balcony (for which Alexis is on trial and in jail). It is tracked to the neighboring apartment of successful and charming hedge fund manager, Farnsworth "Dex" Dexter, (flown by his young nephew). Alexis is cleared of all charges when the drone's footage proves Larson's death was an accident. Dex then attends a Carrington gala and reveals that he and Alexis are already acquainted. His father, Samir Dexter (David Diaan), once sat on the board of Carrington Atlantic, so their friendship (and Dex's crush on her) goes back a few decades. By the following episode, Dex and Alexis have begun a passionate affair. They are married in "Vicious Vendetta", and their wedding is attended by enemies, exes, and estranged family on both sides. For the rest of the series, Dex remains blindly (and carnally) devoted to Alexis. Their sole conflict stems from the actions of her psychotic son, Adam (Sam Underwood). During the finale, Dex survives a plane crash. He is rescued in the wild Appalachians by his wife, her ex, Blake Carrington (Grant Show), and an extraction team. Dex swears eternal love to Alexis at the wreck site, still blissfully ignorant to her toxic past and crimes.
