Kincaid is known as the Hound of Hell, or just the Hellhound.
In Death Masks, we first meet Kincaid when he brought The Archive to Harry Dresden's apartment. He's introduced as driver, bodyguard, and babysitter—and he claims he's trustworthy because he's paid up through April and might find a better offer by then. Ivy says he's ethical in his way. 
Kincaid is super-humanly strong. He cannot see in the dark, but he can see active IR systems with his unaided eyes. He has overcome the issues with the human nervous system that impede accurate shooting, and so has never been known to miss a target. His ability to recover from vicious injuries is greater than that of a wizard, and he does not seem to age, as he still appears in his middle years despite reaching maturity centuries ago.
In Blood Rites, Harry confronts Kincaid on whether he's human, then calls him a liar when Kincaid says he is human. Harry comments that Kincaid shoots and never misses. Plain humans miss sometimes. Harry saw Kincaid hit every target he aimed for at the fight in Wrigley Field in Death Masks.  
- He used Dragon's Breath rounds against Red Court Vampires at the Wrigley Field duel. Kincaid said they were incendiary rounds and he'd turn Harry onto the guy he knew.
In Blood Rites, Harry sees Kincaid through his Sight. Kincaid appears as an enormous, malformed man with curled horns and bat-like wings coming from his shoulders and dragging on the ground behind him.
In Blood Rites, Ebenezar McCoy and Kincaid are bitterly opposed to each other. Kincaid knows of McCoy's position as the Blackstaff of the White Council and about Casaverde. McCoy threatened to kill Kincaid on sight for Kincaid's actions in Istanbul in the 19th century.
In the seriesEdit
- Main article: Death Masks
Fighting erupts at the duel between Paolo Ortega and Dresden and vampires charge the field. In the Mele, Kincaid scoops up The Archive and races to the dugout. Along the way he whips out a gun so fast his arm blurs and he pops the vampire between the eyes, then into its belly, all with perfect aim while running and carrying a child. He incinerates two vamps with specially loaded shotgun from the dugout with perfect aim. Smoothly pulls out a new gun, shoots a vamp leaping at him, spins and literally puts a shot down a vampires throat that was charging him from behind. — When The Archive asks him who broke the sanctity of the duel first, he said he couldn't tell but Dresden was winning. 
Afterward, Harry asks him about his weapons, Kincaid says they're incendiary rounds, good for vamps, but the heat warps the guns and the second shot can blow back on you. It's necessary to use throw-away guns, he knows a guy, he'll have him call Harry.
