Jaimie Lannister

At first glance, outsiders perceive him to be arrogant, cocky, cold, dishonorable, extremely dangerous, disdainful and sarcastic. To a large extent he is arrogant about his own abilities but not without cause. He is arguably one of the greatest swordsmen ever but he does not mock others over minor insults the way Cersei does and he can muster up polite behavior but he is usually very blunt and straightforward. Much like his brother Tyrion, he typically just says what he is thinking and has no reservations about mocking those he perceives as incompetent. Despite this, there were men that he admired (like Ser Barristan Selmy, for whom he squired) and underneath this cold and sarcastic attitude, he is a very complicated man.
