Lady Bat
Lady Bat is a villain from Mermaid Melody Pichi Pichi Pure who first appears in episode 9. He is a servant of Mikeru and, despite name, looks and clothing, he actually is a male. His main attack is “Ankoku no Tsubasa”, a song which can send his enemies in a state of deep slumber. Also, Lady Bat is vampire (with sharp fangs, pointy ears and bat like wings) but, instead of sucking blood, he sucks memories by kissing his victim. He, along the Black Beauty Sisters, Lanhua and Alala, meets his end at the hands of Mikeru, who no longer needs his servants and thus absorbs and kills them.
