Sir Bors and Lionel live for several years at Claudas's court, but they eventually rebel against him and even slay his cruel son Dorin.
Bors is recognisable by a distinctive scar on his forehead, and participates in most of the King's conflicts, including the eventual battle with Claudas which liberates his father's lands.
Bors fathers Elyan the White when the beautiful daughter of King Brandegoris, Claire, tricks him into sleeping with her by way of a magic ring; he later introduces his son into the Round Table.
Several episodes display his virtuous character; in one, a lady approaches Bors vowing to commit suicide unless he sleeps with her.
In another, Bors faces a dilemma where he must choose between rescuing his brother Lionel, being whipped with thorns by villains in one direction, and saving a young girl who has been abducted by a rogue knight in the other.
[1] At the end of the entire Vulgate Cycle, Bors further emerges as the only surviving main character and a successor to Arthur after the King's death.
[2] In Thomas Malory's Le Morte d'Arthur, based on the French prose romance tradition, Sir Bors reluctantly agrees to fight as Queen Guinevere's champion in a trial by combat after she is accused of poisoning a cousin of Sir Mador de la Porte.
Refusing at first, as her usual champion Lancelot had left Camelot earlier because of her, Bors relents after the desperate Guinevere kneels before him.
Together with his brother Lionel, Bors becomes one of Lancelot's most valorous and trusted aides in the ensuing war, during which he barely survives his horseback duel with Arthur's second-in-command Gawain.
