Felix

"You look good, immortality suits you."

Felix is a vampire member of the Volturi guards. His motivations are not at all described in the books. The only cues to discern his character are his physical actions and his talks to Bella and Edward.

Physical description
Bella describes him as "very big, tall, and thick through the shoulders", and that his size reminds her of Emmett Cullen. He is described as having a slightly olive complexion which looks odd combined with his chalky skin. He also has short, cropped, black hair. He is not gifted, unlike most of the Volturi. It is assumed that he is kept in the guard because of his immense strength due to drinking human blood and physicality. He also is thought to be a fighter.

Personality
In New Moon, he is seemingly disappointed when Bella can't stay in Volterra, and Edward seems annoyed by his infatuation with her. In Eclipse, when the Volturi finally notice the chaos, he winks at Bella. In Breaking Dawn, he compliments Bella's "new face" and says it's too bad that she is going to die. Bella sarcastically agrees, and he winks again. He is somewhat of a comedian and of a flirt.

Abilities
Meyer stated that Felix's talent is his fighting and strength. No matter how good anyone else is in physical combat, Felix will always remain one, or most likely, several steps ahead of them. Coupled with his large size, Felix is probably the most physically powerful vampire in the Volturi Guard, if not the world.

Etymology
Felix's name means "lucky, successful" in Latin, it can also mean "happy" and "prosperous" (also in latin) probably referring to his good-natured nature.

Film portrayal
Daniel Cudmore portrayed Felix in the New Moon film, and returned in Eclipse.
