Gabriel

Gabriel had draped himself over the backseat. The gauntleted hand trailed down Ronnie's arm. Even through her suede coat she shivered. "Touch me again, and I am going to feed you that hand." She'd scooted away from him as far as the steering wheel would allow, which wasn't far. Gabriel had touched her several times over on the drive over. Teasing, nothing embarrassing, but it wasn't bothersome.
"Hands are very bony. I prefer a more tender cut of meat. Breast or thigh is my preference," Gabriel said.

(The Lunatic Cafe, page 295, paragraph 1)

* Gabriel is an alpha, but a flawed one. His leadership over his small pard is less than exemplary, resulting in a group of wereleopards that are all submissive in a sexual sense. They are all considered "bottoms" which is a sexually submissive position.

* Gabriel and Christine might have had an encounter at one point, because he quotes a poem by William Blake to her

 "Tyger! Tyger! burning bright/ In the forests of the night/ What immortal hand or eye/ Could frame thy fearful symmetry?"

and she blushes.

* Gabriel and Raina were partners in snuff porno films, with Gabriel starring in many of them as the dominant aggressor and also murderer. 

* In exchange for Jean-Claude and Richard to Cassandra, Sabin and Dominic, Gabriel and Raina get to kill Anita in one of their porno snuff films. However, she ends up killing both of them.
