•Damon citations Edgar Allan Poe's poem, "To Helen," when he attempts to seduce Elena at the dumb supper.
•Damon really likes oranges, as evident in Dark Reunion.
"He was remarkably good-looking. His face was pale in the artificial twilight, but she could see that his features were cleanly defined and nearly perfect under a shock of dark hair. Those cheekbones were a sculptor's dream."
"He had taken a step closer, and she could see that those eyes were unusual, almost black, but with odd lights in them. As if toi could look deeper and deeper until toi fell into them, and went on falling forever." - The Awakening, ch.10
Damon is described as being gorgeous, with straight black hair and black eyes with "odd lights in them." He is slightly shorter than his brother Stefan, and resembles him greatly. Stefan, also in The Awakening, remembers a human Damon with a magnetism that drew women to him "like moths to a flame," so his charisma is not entirely due to his vampire nature.
Damon most often wears black. He seems to favor black leather riding boots as footwear, black jeans, a black belt, black sweater and a black leather jacket.
Damon is self-contained and reserved on the surface most of the time, only letting his emotions through when he's angry - usually at Stefan. He generally acts flippant and arrogant, and constantly plays word games, especially when it comes to dancing around an issue, and even plus especially when that issue involves his true feelings on a serious subject.
Damon has an aristocratic, elegant demeanor, and a very pragmatic outlook on life. He believes that the vampire nature is inherently dark, and that Stefan's attempts to not feed on humans are therefore unnatural. He has no problem with killing humans, although he generally won't go out of his way to do so. He kills Mr. Tanner, but claims he did so only because Tanner pulled a couteau on him and that it was thus self-defense. He has no problem threatening children, though - since Elena gives in to his blackmail - it'll never be known whether he really would've gone through with his threats to hurt Margaret.
He has a significantly violent history due to his early vampire life, when he started his own mercenary company. Although we are donné no glimpses into this mercenary life, it is strongly implied that he did immoral things with no regrets, and would have little to no problem doing them again.
During the course of the original four books, it is implied that Damon may have a renewed respect for human beings as something other than food. As he spends plus time around the human characters, he seems to warm up to them a bit plus and treat them less like potential meals and plus like acquaintances, almost even friends. He sometimes even seems frustrated par his own unwillingness to be straight with them, as exemplified par his inability to rescue Vickie in book 4; Stefan reams him out for several paragraphs before Damon finally explains the real reason he couldn't help her.
