Lady Bat is a villain from Mermaid Melody Pichi Pichi Pure who first appears in episode 9. She is a servant of Mikeru and, despite her androgynous looks, she is actually is a female and considers herself as such. Her main attack is "Ankoku no Tsubasa", a song which can send her enemies in a state of deep slumber. Lady Bat is also a vampire (with sharp fangs, pointy ears and bat like wings) but, instead of sucking blood, she sucks memories by kissing her victim.

Spoiler

She, along the Black Beauty Sisters, Lanhua, and Alala, meets her end at the hands of Mikeru, who no longer needs his servants and thus absorbs and kills them.
