In the post-production of the film, the pallor of the vampires was achieved via D.I. The leadership and organization of the Vampire Nation is once again restored following the ascension of Selene, David, and Lena as the new Vampire Elders. But since the assassinations of the Vampire Elder, Lady Amelia, and the Vampire Council, by the Lycans, the Vampire Elder, Lord Viktor's death at Selene's hand after learning the truth of her family's deaths at his hands, the final Vampire Elder, Lord Marcus' destruction of the main branch of the Old World Coven and its seat of power, Ördögház, and then his death at Selene's hand to stop him and his rampaging brother, William the leadership and organization of the Vampire Nation was scattered and divided. In the novelizations, the Vampire population as a whole is referred to as the "Vampire Nation", consisting of covens traditionally, before the events of Evolution, the two main covens were the Old World Coven (based in Hungary, in the environs of Budapest, with branch covens all-over the Euro-Asian continent), and the New World Coven (based in the United States, in New York). The oldest vampires, the Elders, are, by consequence of their great ages, therefore the most powerful of their race, even stronger than Lycans in werewolf form. They can also die from a broken neck, blood loss, nightshade poisoning, dismemberment, mutilation and other extreme physical trauma, especially if their head or heart is destroyed or removed. They do not possess any of the mystical weaknesses of mythological vampires (crosses, holy water, garlic, stakes, etc.) however, they are highly vulnerable to ultraviolet radiation. These abilities are maintained by feeding on blood, which is a prominent factor in their healing capabilities in addition to being strengthened with age. Biologically immortal transgenics, the vampires of Underworld display most of the prominent superhuman physical prowess commonly seen in popular culture, including superhuman strength, reflexes and speed, as well as an inhuman resistance to injury and accelerated healing. At all times, the upper lateral incisors and upper canine teeth on all vampires are elongated and come to a sharp point. When they metamorphose, their eyes turn a shade of electric blue or bright gold, while their upper canine teeth lengthen to become pointed fangs.

Their metamorphosis is not nearly as startling as their lycan counterparts.
