Selene, the central character from the Underworld film series, is a fierce and enigmatic vampire warrior known as a Death Dealer. Played by Kate Beckinsale, she is striking in appearance, often dressed in sleek black leather with piercing blue eyes and an intense, determined demeanor. Selene is a highly skilled combatant, specializing in hunting and killing Lycans—werewolves—in a centuries-old war between the two species. Despite her loyalty to the vampire coven, she becomes disillusioned upon uncovering deep secrets about her own past and the truth behind the war. Her cold, stoic exterior masks a complex emotional core, especially as she forms a bond with the human-turned-hybrid Michael Corvin. As the series progresses, Selene evolves from a loyal servant of the vampire elite into a powerful, independent force challenging the corrupt hierarchy and fighting for a new future. Her journey is one of vengeance, discovery, and transformation, marked by her growing strength, resilience, and willingness to defy tradition in pursuit of justice and truth.
