He has grey, or blue-grey, eyes, although they change color sometimes because of his vampire status. White Court vampires retain a natural color while they are not Hungry, and lighten to grey, silver, chrome and white consecutively as the Hunger demon gains more influence. His hair is shoulder-length (though he cuts it after it gets burned by a flaming arrow in Small Favor) curly, and black. He has very white teeth and a good build.
Harry describes him as "a predator angel", "unwholesomely good-looking", "awfully pretty to look at", "like someone's painting of the forgotten Greek god of body cologne", "the high priest of Bowflex", "a young man whom fathers of teenage daughters would shoot on sight". "[He] made all those Spartans in that movie look like slackers, and he didn’t even use an airbrush."(reference needed) Anastasia Luccio thinks that Thomas doesn't look like Harry except for the jaw and the shape of the eyes.
It is gradually revealed that Thomas is a deeper, more caring person than he wants to reveal. His flaky attitude turns out to have a purpose—all his vampire brothers have been murdered by their father, and he risks putting his lover Justine in danger if he shows more than passing affection for her, as well as a wish to be underestimated by his enemies.
In the case of others, especially ones who are a danger to his loved ones, he can be rather brutally blunt, even downright callous, such as describing Waldo Butters as a coward and advising Harry that the nervous coroner would only endanger him.
Thomas has a sense of humor and irony about his situation and crazy family. He does, however, experience guilt over his incubus-like nature, and tries to minimize the damage he causes—perhaps the legacy of his late mother.(reference needed) Like his brother, he is a monogamist at heart, and tries to keep his seductiveness in check.(reference needed) After being tortured by the Skinwalker, Shagnasty, his personality takes a change toward being more predatory.
His dislikes include Red Court vampires, unnecessary clothing (i.e. shirts, shoes) when indoors, polka music, secrets (that he isn't in on), and his father.(references needed)
He is a massive slob: he lives almost exclusively on beer and microwave meals, and leaves the private rooms of his chic apartment an undecorated mess.
Thomas's approach to any given combat is with a maximum of power, speed, and aggressive ferocity.
In Turn Coat, Thomas is a White Court Celebrity after the coup attempt.(reference needed)
In Changes, his personality seems to be more like in the past, even regaining his joking manner. He is more entrenched in White Court politics with his sister.(reference needed) After he thinks that Harry has died he mournes deeply and stops even trying to seem human, not wearing shoes outside in the winter, or changing his clothing. He just drinks, until Justine finds a way to cher him up.(reference needed)
He's born on Valentine's Day.
Thomas Raith is the son of White Court vampire Lord Raith and human wizard Margaret LeFay. His mother left when he was about five; she had another son, Thomas' half-brother Harry Dresden. Thomas has seven other half-siblings on his father's side: Lara, Inari, Elisa, Natalia, and three others, one of whom is allegedly insane and kept "in the attic."  He also has several cousins, including Madeline and Madrigal.
- He uses a Desert Eagle pistol;(reference needed)
- a sawed-off double barrelled shotgun;(reference needed)
- an U.S. Cavalry saber and a kukri on a regular basis; a "new toy" Thomas has become fond of;
- Falcata sword.
Thomas is faster and stronger than a normal human. His kind age slowly, if at all. He can heal from almost anything short of actual death, as long as he keeps his Hunger demon fed.(reference needed) He's a good swordfighter and a decent marksman(reference needed), a good liar and consummate actor.(reference needed)
Like all of the Raiths who feed on lust, he is burned by the touch of one who has the mark of true love on them, or touching objects embedded with love (such as wedding rings).
His Hunger is described in Backup as being strongest of the Raiths, except Lara, once Lord Raith had been crippled by Margaret LeFay's death curse. With the deaths of senior Lords in White Night, his ranking in raw power across the whole court has been increased. The battle against his Hunger is a constant struggle for Thomas, and not one that he always wins.(reference needed)
His father, Lord Raith, murders his own sons before they get ideas of knocking him off or out of power.
He hates his father and his psychotic cousins, which is understandable as they seem to regularily try to kill him. He seems to have a decent relationship with Lara, though she's manipulative and emotionally distant. He is fiercely loving and protective of his baby sister, Inari.(reference needed)
"Thomas would sooner tear off one of his arms than see one of his siblings hurt. He's quite irrational about it."
He is especially close to Harry himself, often confessing things to him that he wouldn't tell others. Ever since the two have found themselves half-brothers they have become quickly close. Thomas often refers to Harry as 'little brother' or just 'brother'. He seems keen to keep a close connection to Harry and the feeling seems to be mutual due to a lack of proper family for both. Thomas often gives Harry advice on things, though mostly encouraging him to get over Susan and ask Murphy out. Though they both annoy each other, they both have a genuine affection for each other and seem to understand each other well.(reference needed)
He almost kills her in Blood Rites, but manages to stop at the last possible moment, despite the seeming impossiblity. She is weak for awhile, but eventually recovers when she should have died. However, this causes her to have the mark of true love on her, and Thomas can no longer touch her directly without burning himself. Harry sees this as very tragic.
In Turn Coat, Thomas and Harry meet Justine at Zero. Thomas drops to his knees at her feet and wraps his arms around her waist while she wound her arms around his neck. They embrace and hold each other a long time with justine dressed in a flattering white rubber outfit that protects Thomas from getting burned by touching any part of her. Harry thinks the irony of their relationship is like a "kick in the balls".

Word of ButcherEdit
He is initially portrayed as very flippant and seemingly arrogant, even swearing by "my towering ego" and acting in a rather flaky manner. He seems to like Harry from the very moment he meets him and was there to help him from the start, already knowing that his mother had another son.
"Thomas and Justine's relationship is really weird. I know what the relationship is in my head like right now. They're actually happier now than they've been in ever. But it's all happening behind the scenes and nobody can see because Thomas has to have his bad ass vampire face on whenever he's in public. But when they are alone together, nothing else going on, they're like totally cute. Justine wears like these grownup version of footie pajamas so that she can snuggle up next to him on the couch and watch TV without actually burning him. They don't have like a normal relationship or anything like one, but they've kinda adjusted, they're fairly happy. You don't go around letting the other vampires go "Oh how cute, I'll have to get to that one of these days," Harry doesn't see that."(reference needed)
