  ====''A Game of Thrones'' and ''A Clash of Kings''====
  In ''A Game of Thrones'', he acts as bodyguard and servant to Prince Joffrey Baratheon, who calls him Dog. While escorting Sansa home, he reveals to her how his face was scarred and expresses much resentment of his brutish older brother and towards the concept of knighthood in general. Clegane leads the attack on the Stark forces in the Tower of the Hand. 
  He is named a knight of Joffrey's Kingsguard towards the end of ''A Game of Thrones''. Clegane advises Sansa to do whatever Joffrey tells her to do as the best way of staying alive. He is often assigned to guard Sansa, trying to protect her from Joffrey's abuse in ''A Clash of Kings''. He flees King's Landing during the Battle of the Blackwater, due to the widespread use of wildfire, a fictional substance similar to Greek fire.
