Selene Delacroix

Selene Delacroix is the main protagonist of the 'Underworld' film franchise (2003-present), portrayed by actress Kate Beckinsale. A vampire and skilled warrior known as a 'Death Dealer,' Selene is trained to hunt and kill Lycans (werewolves), the sworn enemies of vampires. The character is defined by her tragic backstory—her family was killed by Lycans, and she seeks revenge—and her eventual role as a bridge between the warring vampire and lycan species. Selene is visually iconic, known for her sleek black leather combat outfit, pale complexion, dark hair, and piercing blue eyes. Throughout the film series, she evolves from a loyal vampire soldier following orders without question to a complex antihero who questions the morality of the eternal war between species and forges unexpected alliances. Her relationship with Michael Corvin, a human-lycan hybrid, becomes central to the narrative and drives much of the series' emotional core. Selene is depicted as exceptionally skilled in combat, possessing superhuman strength, agility, and weapons expertise. She represents a particular archetype in popular culture—the dark, enigmatic, powerful female warrior—and has become an iconic character in the action-horror genre. The 'Underworld' franchise has spanned multiple films and other media, with Selene remaining the constant through the expanding mythology.
