  ===Appearance and personality===
  Stannis is frequently described as a large and sinewy man that towers over others, such as Davos Seaworth and Jon Snow, a Baratheon trait. He lacks the long black hair of his brothers, and is instead balding, although he keeps a close-cropped beard of the signature Baratheon black. His face is described as 'tight like cured leather' with hollow, gaunt cheeks. His eyes are described by Asha Greyjoy as 'deep, sunken pits', with a powerful stare that suggests an 'iron ferocity'.
  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.
  Although Stannis suffers from a lack of support and resources during the War of Five Kings, he is frequently described by his adversaries, including Tywin Lannister, as the most dangerous rival claimant. Above all he is characterized by his fearless and uncompromising pursuit of justice and duty - he is described by Varys in this way: "His claim is the true one, he is known for his prowess as a battle commander, and he is utterly without mercy. There is no creature on earth half so terrifying as a truly just man."
