Blake Carrington

Blake loses his custody fight when Steven marries Claudia Blaisdel. However, father and son reconcile when Blake and Krystle remarry. Still seeking revenge, Alexis enlists Rashid Ahmed to sabotage a deal he has with Blake. Blake is broken.

Blake manages to save his company, but he mourns Fallon's death in a plane crash. Blake also learns that he has an illegitimate half-sister, Dominique Deveraux. He accepts his sister after his father, Tom Carrington, admits on his deathbed that she is his daughter. A few months later, Blake learns that Alexis had another child after they divorced, a daughter she named Amanda. Although Alexis initially denies that he is Amanda's father, Blake eventually learns that she is, in fact, his daughter. At Christmas, Blake is thrilled when Krystle has a baby girl they name Krystina. Although her health is fragile at first, she survives and thrives. Blake grows jealous of Krystle's friendship with playboy Daniel Reece. Meanwhile, Lady Ashley Mitchell attempts to seduce Blake. Someone has photos taken of both Blake with Ashley and Krystle with Daniel, and sends them to the other spouse. However, Blake and Krystle declare their love for each other. The entire family attends the wedding of Amanda and Prince Michael of Moldavia, and rebels storm the chapel and spray the church with bullets.

Blake and his family survive the attack. Upon returning to Denver, Blake enters a business deal with Jason Colby, and is shocked to discover that Fallon is alive, suffering from amnesia, and married to Jason's son, Miles. Krystle is kidnapped by Joel Abrigore and replaced with a look-alike named Rita Lesley, who slowly poisons him on Joel's orders. Blake's health deteriorates until he is almost completely incapacitated. Sammy Jo learns the truth and helps Krystle escape captivity. Joel and Rita disappear. Blake is furious when his brother Ben returns to Denver. In league with Alexis, Ben sues for his share of their late father's estate. Blake mortgages his house and holdings, expecting to gain control over ColbyCo. Thanks to Ben and Alexis's interference, he loses everything, including his lucrative South China Sea oil leases. In the season finale, he learns that Alexis has bought his house. Furious, he grabs her by the throat and starts to strangle her.

Krystle pulls Blake off of Alexis. Blake learns that his hotel, La Mirage, has burned down and that several people, including Claudia, have perished in the fire. Blake is charged with arson, but eventually the charges are dropped when it is revealed that Claudia was responsible for the blaze. As Blake continues to try to regain his empire, he discovers that the land he inherited from his mother is rich in natural gas. However, he is forced to temporarily halt his plans to develop on the land when Alexis and Ben learn of its existence. Soon after, Emily Fallmont gives incriminating information about Alexis and Ben to Blake, who uses it to force them to relinquish their ownership of Denver-Carrington and all its holdings back to him, including the South China Sea oil leases. Later, Blake, Alexis, and Ben are in southeast Asia inspecting an oil rig when it catches fire. Ben rescues a trapped Blake moments before the rig explodes, which eventually leads to their reconciliation. Blake awakens in the hospital with no memories of the last 25 years. Alexis has him discharged from the hospital and convinces him that they are still married. However, when Krystle finds them, Blake's memories return. Blake and Krystle's daughter, Krystina, falls ill and needs a heart transplant. A donor is found and Krystina is saved, but the donor's mother, Sarah Curtis, kidnaps Krystina. She is later recovered, unharmed. In the season finale, Blake and Alexis legally adopt Adam.

Blake runs for governor, opposed by the incumbent and Alexis. After a long and grueling campaign, both he and Alexis lose. Not long after, Blake returns home to find his bedroom in disarray and Krystle missing. He says, "Oh, Krystle, I thought we had more time!"

Krystle has a serious brain tumor and must have risky surgery. They fly to Switzerland, where the surgery is successful, but Krystle is left in a coma. A body is found at the bottom of a lake on the Carrington property. It turns out to be Roger Grimes, the man with whom Alexis was having the affair that caused her and Blake's divorce. Roger has been dead for 20 years, but the cold temperatures in the lake preserved his body. Ultimately, it is revealed that 8-year-old Fallon had shot Roger after finding him beating Alexis, and Blake's late father Tom had hidden the body in a mine under the lake to protect Fallon. The situation is complicated by the fact that the mine is full of stolen Nazi treasure, hidden there by Tom. In the last episode of the series, Blake learns that the police captain investigating Roger's murder is searching for the treasure. Blake attempts to force a confession. The captain pulls a gun, and they both shoot. Blake is left lying in a pool of blood.

Three years later, in Dynasty: The Reunion (1991), Blake has fully recovered from his gunshot injury and is being released from jail after being exonerated for the fatal shooting of Captain Handler. Along with his sons, Steven and Adam, and former son-in-law Jeff Colby, Blake attempts to regain control of Denver-Carrington from an international consortium. Krystle returns, having come out of her coma, but has been programmed by the Consortium to assassinate Blake. Her love for Blake proves to be too strong, and breaks the Consortium's control over her.
