Joham

Joham is a vampire, or Libishomen, living in South America; It is said that he considers himself to be a scientist creating a super race of half-vampire half-human children. He is an incubus and seduces beautiful women, such as Pire, from their homes, and leaves them as soon as they become pregnant. He later attempts to find the surviving hybrid children. Including Nahuel, he has fathered three daughters, possibly more, as he does not monitor the births. He taught his daughters that they were goddesses and that humans were animals, making them remorseless. Nahuel mentions that they reached maturity sometime before the events of Breaking Dawn.

His hair is black and his skin color a very dark brown, both of which Nahuel has shown to have inherited, hinting that Nahuel resembles Joham in appearance.

Appearance
In Breaking Dawn when The Volturi arrive in Forks to "punish" the Cullens, Nahuel suggests that Joham is the person they really should look up, implying his days are numbered.
