Draculina is one of the three types of lady bats under Dracula's command, along with the Werebat and Lilith. She's a female vampire and appears as a winged demoness who commands a bat to aid her in battle.
Draculina attacks by taking flight as soon as she notices an enemy and then tries to swipe at them with the claws of her feet or by commanding her bat to attack. The bat also provides her some protection, as it will keep on flying around her, making it more difficult getting near her to attack. If the bat is killed first, she will be unprotected for a short time until she summons another one.
Draculina appears to be the most loyal of Dracula's servants. If her own name is not evidence enough, when killed, she will use her last ounce of strength to plead in agony for her master ("Lord Dracula!").
