He is the grandson of the previous king Jaehaerys I Targaryen and the husband of Queen Aemma Arryn and later Queen Alicent Hightower. He is the father of Queen Rhaenyra Targaryen and the short-lived Prince Baelon Targaryen through his first wife Aemma and King Aegon II, Queen Helaena, Prince Aemond, and Prince Daeron Targaryen through his second wife Alicent. He was a dragonrider who was bonded to the dragon Balerion until it died of old age. While his cousin Princess Rhaenys had a better claim to the throne, a Great Council at Harrenhal voted Viserys to succeed his grandfather King Jaehaerys. His first marriage to Queen Aemma Arryn resulted in a daughter, Rhaenyra, and two miscarriages for sons. During the birth of the second son, Baelon, Viserys orders a C-section in an attempt to save his life, but both Baelon and Aemma die in the process. Viserys then proclaims his daughter Rhaenyra as his heir, defying his younger brother Daemon, and begins to groom her as his successor, informing her of Aegon's prophecy. Viserys soon remarries to Lady Alicent Hightower. Later in life, Viserys becomes incredibly weak while suffering from a form of leprosy. A weakened Viserys is treated with Milk of the Poppy, making him delirious and bedridden. While he is incapacitated, the Hightowers and their allies prepare to make Aegon the new heir, while Rhaenyra attempts to keep her father's wishes of making her the next Queen. Dying, and believing he is talking to Rhaenyra, he tells Alicent about Aegon's prophecy, but Alicent believes he is talking about the destiny of their son Aegon.

She is also the childhood companion of Princess Rhaenyra Targaryen, with them having grown up together in the Red Keep. Following the death of Queen Aemma Arryn, Alicent's father pressures her to get close to the grieving Viserys. Viserys later goes against the advice of the Small Council and marries Alicent, who soon gives him a long-sought-after male heir with their son Aegon. When she overhears Otto and Viserys discussing Rhaenyra's exploits with Prince Daemon Targaryen, she confronts Rhaenyra privately, who denies the rumor, which begins to create a rift between them. Alicent is informed by Larys Strong that Grand Maester Mellos was ordered to discreetly deliver moon tea, which is used to abort pregnancies, to Rhaenyra, and questions Ser Criston Cole on the matter, who confesses that he broke his oath and slept with her. Feeling betrayed by her closest friend, Alicent surprises all the guests when she attends the wedding of Rhaenyra and Ser Laenor Velaryon wearing a green dress that matches the colors of the flames House Hightower burns when they go to war. Ten years later, Alicent and Rhaenyra had become more distant, and she rejects Rhaenyra's proposal to marry Rhaenyra's eldest son, Prince Jacaerys Velaryon, to Alicent's daughter Helaena due to Rhaenyra's children being bastards. She indirectly causes the deaths of Lord Lyonel Strong and Ser Harwin Strong, when she mentions to Larys that she wanted her father to regain his position as Hand of the King. She attends the funeral of Lady Laena Velaryon at Driftmark, but following an altercation that results in Rhaenyra's second eldest son Prince Lucerys Velaryon partially blinding Alicent's son Aemond, Alicent attempts to have Lucerys' eye gouged out in return, and when refused, she wounds Rhaenyra. Six years later, on Viserys' deathbed, he mistakes Alicent for Rhaenyra and mutters parts of Aegon the Conqueror's dream regarding the "Prince That Was Promised" which Alicent misinterprets as Viserys wanting their eldest son Aegon to succeed him as king instead of the chosen heir Rhaenyra. Following her husband's death, Alicent urges her father to help crown Aegon instead and Otto reveals that he and the majority of the Small Council had been planning Aegon's succession for years. Appalled by this, she orders Larys to dismantle Mysaria's spy network which Otto had been using for his advantage. When Otto travels to Dragonstone to request Rhaenyra's surrender and swear fealty to the newly crowned King Aegon II, Alicent tries one final time to repair her friendship with Rhaenyra by sending a message with her father that only Rhaenyra would understand, but the death of Rhaenyra's son Lucerys soon ends any hope of a peaceful resolution.

In season 2, Alicent has begun a sexual relationship with Criston, who she is sleeping with during the murder of her grandchild Prince Jaehaerys Targaryen. She later attends the funeral of Jaehaerys and helps calm her daughter Helaena when she is on the verge of a panic attack due to her grief.

Six years later, following the death of King Viserys I Targaryen, Larys apprehends Lord Allun Caswell during his attempt to flee King's Landing and has him executed.

He later personally kills one of his son's killers and orders the public hanging of every ratcatcher in the Red Keep, one of whom was an accomplice in Jaehaerys' death.
