Drago was a Vampire Death Dealer who worked under Amelia, mentioned only in the Underworld: Evolution novelization. He did not appear in the film.
In 1202 AD, Drago was a recent recruit to the Death Dealers, having only been recently made a Vampire. Before becoming a Death Dealer, Drago was a foot soldier in a human army.
Underworld: Evolution[]
Drago was one of a contingent of Death Dealers led by the three Vampire Elders, Amelia, Marcus Corvinus and Viktor, in pursuit of Marcus's twin brother, William. When they arrived at a secluded village, they discovered that William had already massacred the townspeople, and they began to burn the bodies.
When the village exploded into chaos due to the massacred citizens becoming Werewolves, Drago rushed to the aid of another Vampire, catching the attention of Amelia. Seconds later, a second Werewolf jumped onto Drago, tearing his face off, despite Amelia's efforts to intervene. With the death of Drago, Amelia thought to herself that she wanted to have him promoted, and that his passing was a waste of a Vampire life.
