Carmilla is a major vampire antagonist in Castlevania, serving as one of the central leaders of the vampire court in Styria. Intelligent, ambitious, and ruthlessly pragmatic, she seeks to build a new vampire empire by overthrowing the old order and expanding vampire dominance over humanity. She is portrayed as charismatic yet cruel, with a strong sense of entitlement and contempt for weakness. Her role in the series is that of a powerful political and military threat, driving much of the conflict through her schemes and hunger for control.
