Boros Blount is a recurring background character in the first, second and third seasons. He is played by an unidentified extra and is first identified by name in "Blackwater." Ser Boros Blount is a member of the Kingsguard and defends King Joffrey Baratheon as he defended King Robert Baratheon before him.
During the Battle of the Blackwater, Ser Boros and Ser Mandon Moore remain at the side of King Joffrey as he oversees the city's defenses alongside Tyrion Lannister, the Hand of the King. When Queen Cersei learns that the forces of Stannis Baratheon have almost breached the walls, she orders Joffrey to be brought into the safety of the Red Keep. When told that he has to leave the wall at the behest of Queen Cersei, Joffrey, who has never shown much courage in the face of adversity, complies and orders Ser Mandon and Ser Boros to aid Tyrion and fight on in his stead. They stand behind Tyrion as he gives a speech to rally the troops. 
During the feast to celebrate the wedding of Tyrion Lannister and Sansa Stark, King Joffrey taunts Sansa by telling her that he may rape her, and have Ser Meryn and Ser Boros hold her as he does it.
Ser Jaime goes over the security plans for the Royal Wedding feast with Ser Meryn Trant, mentioning the place in which Ser Boros will be stationed

In the booksEdit
Boros Blount has a more prominent role in the A Song of Ice and Fire novels. In the TV series he is merely a background character, and many of his lines and actions are given to his fellow Kingsguard Ser Meryn Trant. Blount is a member of Robert Baratheon's Kingsguard. He is a short-tempered, ugly man with a broad chest and short, bandy legs. He has a flat nose, jowls and grey hair. Ser Jaime Lannister considers him an angry paper shield. Many characters throughout the series think of Blount with contempt due to the man's cowardice. Like Trant, Varys considers him one of "Cersei's creatures".
Boros, along with the other five Kingsguard members present, openly laughs when his Lord Commander Barristan Selmy is unlawfully dismissed from service.
In the books, it is Boros Blount the one who carries out Joffrey's orders to undress and beat Sansa Stark instead of Ser Meryn. He's also absent during the Battle of the Blackwater, having been dismissed for cowardice after yielding Prince Tommen to Tyrion's agents when the Prince is smuggled out of King's Landing to protect his life from the impending attack by Stannis Baratheon. However, he is reinstated to the Kingsguard by Tywin Lannister upon his return as Hand of the King, to fill the vacancy left by the Hound when he deserted. Jaime thinks that his sister should have never dismissed Boros, but their father only compounded the shame by reinstating him.
Following Joffrey's death by poisoning, Jaime makes Boros the offical food taster for King Tommen, as he deems him unfit to do anything else. Boros considers this a shameful post for a knight of the Kingsguard, but he complies in this new role.
In the Trial of Tyrion Lannister, Boros testifies after Meryn Trant, repeating what Meryn said. Whatever mislike Boros may harbors toward Cersei for dismissing him from the Kingsguard, he says the words she wants all the same.
Sansa thinks that Boros Blount is "the worst of the Kingsguard, an ugly man with a foul temper, all scowls and jowls", which is quite an accurate description of him.
