Furaiki

Furaiki was a Droid belonging to Petz which appeared in episode 64. She carried around a large drum and drumsticks which emitted electrical energy.

Her mission was to create a powerful thunderstorm in order to scare Chibiusa (who was afraid of them), so that in her fright, she would release a moonbeam; this would allow the Black Moon Clan to pinpoint her location and capture her.

Trivia

* Her name literally means "demon of wind and thunder."
