Caius

"So the Cullens sided with the shape-shifters against our own kind-against the friend of a friend, even."

- Caius on the Cullens' relationship with the werewolves

Caius is one of three vampires in Italy who live what Edward described as a very civilized and educated lifestyle. Caius has a wife named Athenodora who is not very well known and rarely leaves Volterra.

Early Life
Caius was born about 1000 BC, and at some point became a vampire. He later joined the Volturi, along with Aro and Marcus. It is unknown if Caius ever met or knew Didyme, Marcus's wife and Aro's genetic sister, or if he knows that Aro killed her himself. Later two female vampires joined the Volturi: Sulpicia and Athenodora, who both were cousins. Athenodora later became Caius's wife. Some 2000 years before Breaking Dawn, he was nearly killed by a werewolf in a fight, and never got over it, so he hunted werewolves to near extintion. He also participated in the extermination of the Immortal Children, which he deemed to be dangerous.

New Moon
In New Moon, Caius was insistent that Bella not be allowed to leave Italy alive. When it was determined that Edward planned to change Bella, Caius was disappointed, but Aro assured him that they would try again to persuade them to join.

Breaking Dawn
hahahaha After the confrontation, Edward tells everyone that Caius has great fear of werewolves - not the shape-shifters of La Push- but "real" werewolves and had them hunted to near-extinction. This is because he was nearly killed in a fight with a werewolf two thousand years ago.

Physical description
Caius has very pale skin that is almost translucent. It is described as being similar to onion skin. His hair is shoulder length and as white as his skin.

Personality
Caius, like the rest of the Volturi, is cruel and power-hungry, and appears to be negative; an example of Caius's negativity is when he didn't want Bella to leave Italy alive in New Moon. While Carlisle Cullen was staying with them before coming to America, he respected the Volturi for their refinement, but didn't want to be persuaded by them to drink human blood and feed off humans. Caius seemed to have taken this cHAHAHAourse also in drinking human blood and feeding off humans.

Edward Cullen states Caius seems to have a great fear of werewolves after nearly being killed in a fight by a werewolf some 2000 years before; Edward also states that Aro seems to be afraid of Bella, but it is unknown whether or not Caius is afraid of Bella also.

Name etymology
The name "Caius" seems to be Latin for the word "rejoice" ("Caius" is procounced kah-EE-us). The name also seems to be Roman. The name could also be spelled as "Gaius". Gaius or Caius was a common Roman praenomen (given name) of uncertain derivation. It has been suggested it might relate to the Latin 'gaudere', "to rejoice". It might also be linked to an Etruscan phrase, or to the Greek 'Gaia'. It was used among the Romans as a firstname, with examples such as Gaius Julius Caesar and Gaius Caligula. It is mentioned in the Bible and is the name of a saint as well. Caius is now considered a variant of Gaius, but was probably the original spelling. At the time the letter C, which occupies in the Roman alphabet the place of the Greek Gamma, was in some cases pronounced [G]. Caius (pronounced "Keys") is also the common short name for Gonville and Caius College, Cambridge, England.

Film portrayal
Jamie Campbell-Bower has been cast in the role of Caius for the upcoming New Moon film.
