Stannis' most prominent characteristics are his flinty and austere demeanor, unrelenting stubbornness, and powerful sense of duty and justice, the latter of which he is notorious for throughout Westeros. He rarely forgives a slight; Jon Snow once comments that "Stannis Baratheon with a grievance was like a mastiff with a bone; he gnawed it down to splinters." His signature tic is grinding his teeth, often in the face of unpleasant or unforeseen circumstances. He is a renowned commander, sailor, and warrior, although he is a better tactician than fighter. Stannis is known for his brusqueness and lack of tact in social situations and finds himself uncomfortable around women, including his own wife. He abhors brothels and once tried to have them banned from King's Landing, which made him unpopular with the smallfolk there. He dresses plainly in dark clothing and is rarely seen without his sword and dagger. Stannis is plagued with bitterness at the lack of respect and affection he has been shown by his older brother King Robert, and even in childhood was described by the Baratheon family maester as "the most unloved of the three"; a "solemn and joyless" child "mature beyond his years". Stannis is an atheist, despite claims that he is being manipulated by the red priestess Melisandre.
