Zane

Zane is one of the main antagonists (he was killed in part IV by Lucas), and he's Siena's older brother.

Background
Not much is known of Zane's past, but he was born to two vampires, and he was once married to a vampire woman (who was killed by Jake).

Personality
Zane was like all the other antagonists in the series; he's sadistic, smart and cunning.

Love Interests
The details between Zane and his late wife are unknown, but Zane loved her very much, and he grew mad with rage and revenge when Jake killed her. Wanting to let Jake feel the same feeling of losing someone dear, Zane captured Dawn in part III, planning on killing her but she was saved by Jake.

Siena
Zane loved Siena very much because she was his little sister and after Zane's wife's death, his only family. He trusted her with his life, but when Siena decided to change to the werewolves' side, Zane tried to kill her, but she managed to escape. Zane was even more disappointed in her when he found out that she had told Jake and the others his weakness (that only a hybrid could kill him).
