amela Sue Martin starred as Fallon Carrinton Colby from it's series debut on January 15, 1981 through three seasons leaving the show in 1984.

Fallon is Blake's "little, cute, spoiled and rich favorite daughter." Alexis gave birth to her in 1956, and growing up, Fallon got a very close relationship to her father and her brother. Blake was always there to make sure she was fine, she got everything she wanted. Nothing was good enough for his little darling. When her parents split up, Fallon had big troubles coping with it, but got comfort from Steven. When Blake and Krystle were getting married, Fallon returned to Denver for the wedding, after being in Greece. She saw Krystle as the wicked stepmother and did not intend to show any kind of positive emotions towards her father's new bride. But after getting to know Krystle as the warm and sensitive person she really was, Fallon changed and became Krystle's close friend. As a result of a business agreement with Cecil Colby, Fallon married his nephew Jeff in 1981. Their marriage had its ups and downs, and there were good times as well as bad.

In 1982, she gave birth to a son whom they named after Blake. He got the nickname "LB" (Little-Blake). In 1983, the marriage broke, and Fallon divorced Jeff. Just before the divorce, Fallon took a job as a manager at Blake's old hotel, La Mirage. She became a good dealer in the hotel business, and learned a lot. She had several affairs during these years, with people like Peter De Vilbis, Mark Jennings and Nick Toscanni. But her strong love for Jeff had grown, and they decided to get married again in 1984. But Fallon was suffering from terrible headaches after an accident, and in the middle of the wedding she escaped in panic. Her car wreck was later found, but Fallon was gone.

(**NOTE: This was the last of Pamela Sue playing this character. British actress and daytime soap star Emma Samms took over the role in 1985.) Jeff searched for her for months, but she was eventually assumed dead. But a year later, she showed up in Los Angeles, suffering from amnesia, where she met Jeff's half brother, Miles. She was involved with him for a while, but she eventually got her memory back, and re-married Jeff. They moved to California with LB, where they lived for two years ("The Colbys"), and she gave birth to a daughter, Lauren. In 1987, Fallon had a terrible experience; she was abducted by aliens in the desert. Jeff found her unconscious in the desert, and never believed her story. After this their marriage fell apart again, but they managed to keep a beautiful friendship as they moved back to Denver. Fallon inherited her mother's good looks and taste in men, and she changed through "Dynasty" from being Daddy's little spoiled girl, into a responsible, caring and still charming woman.
