<P> Cersei Lannister ( season 1 -- present ) portrayed by Lena Headey . Cersei Lannister of House Lannister and House Baratheon , Queen of the Seven Kingdoms of Westeros , is the wife of King Robert Baratheon . Her father arranged the marriage when she was a teenager , initiating himself as a political counselor for King Robert . The Lannisters are the richest family in Westeros , which is why Robert was interested in a marriage between them . Cersei has a twin brother , Jaime , with whom she has been involved in an incestuous affair from early childhood . All three of Cersei 's children are Jaime 's . Cersei 's main character attribute is her desire for power and her deep loyalty to her father , children , and brother Jaime . Cersei learns that her husband Robert is in danger of finding out that the children he sees as his heirs to the throne are not his . Robert meets his end as the result of a boar attack on a hunting trip , before Ned Stark tells him of the truth about his children . Cersei works quickly to instate her oldest son , Joffrey , on the throne , with her as his chief political advisor and Queen Regent . Joffrey quits listening to his mother , and by the beginning of the second season her father decides Cersei does not exercise enough control over her son , and her father sends his youngest son Tyrion as an additional political advisor . Cersei and Tyrion do not get along , and constantly try to undermine each other 's authority over the crown . As of the end of season 2 , Tyrion has accumulated more sway over the Iron Throne , and has shipped Cersei 's only daughter off against Cersei 's will to be married to the prince of Dorne . In season 3 , she takes pleasure in Tyrion 's diminished position and taunts him for being forced into a marriage pact with Sansa Stark , only to be told by her father that he intends to marry her to Loras Tyrell . At the end of the season , the two siblings ponder at their respective marriages , and Cersei reunites with Jaime in her bedchamber as he unexpectedly returns from captivity . In season 4 , she has Tyrion arrested after Joffrey is fatally poisoned . It is implied that she knows Tyrion 's guilt is highly unlikely , but just wants to see him dead , though Jaime refuses to carry out the order . Indeed , at Tyrion 's trial , it is obvious that Cersei has manipulated the entire procedure so that the only witnesses ( herself , Lord Varys , Meryn Trant , Grand Maester Pycelle and Shae ) give either incomplete or entirely false testimonies to implicate Tyrion and Sansa further in the murder . When Tyrion demands a trial by combat , Cersei quickly chooses Ser Gregor `` The Mountain '' Clegane as her champion to diminish Tyrion 's chances of acquittal , and has Bronn betrothed to a noblewoman so that Tyrion can not choose him as his champion . Cersei 's wish comes true when Tyrion 's champion , Oberyn Martell , is killed by Clegane , but she still refuses to marry Loras , even threatening her father with revealing the truth about her relationship with Jaime and the parentage of her children . Tywin rebuffs her threats , though he himself is killed by an escaping Tyrion soon afterwards . Cersei attends Tywin 's funeral and later orders a bounty on Tyrion 's head . Cersei and Jaime receive a message from Dorne : a small viper statue with a necklace in its fangs . Cersei tells Jaime that the necklace belongs to their daughter , Myrcella , who was sent to Dorne by Tyrion . Jaime tells Cersei that he will travel to Dorne and bring Myrcella back . Cersei meets with two hunters who have brought her a severed head , though she is disappointed to find that it is not Tyrion 's head . Qyburn lays claim to the head for his research and the two walk to a small council meeting . With the office of Hand of the King vacant , Cersei tells the council that she will stand in temporarily until Tommen chooses a new Hand . She appoints Mace Tyrell as the new Master of Coin and Qyburn as the new Master of Whisperers . When Cersei tries to appoint her uncle Kevan as the Master of War , he declines , telling her that as the queen mother she holds no power , and has no interest in serving in
