Furaiki

風雷鬼

Furaiki was a Droid owned by Petz that appeared in episode 64. She carried a large drum and drumsticks that emitted electrical energy.
Her mission was to create a powerful thunderstorm 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."
