Pakupaku is a Lemure sent by Jun Jun to fight the Sailor Senshi. He is a gigantic fish monster, and appeared in Episode 32 of Sailor Moon Super S.
When Jun Jun extracted the dream mirror of a man who was feeding fish (and who was mistaken for Chibiusa's boyfriend), the Sailor Senshi came to stop her, so she summoned Pakupaku to fight them. He ate the dream mirror and then tried to eat Sailor Chibi Moon, but Tuxedo Mask stopped him, closing his mouth with his rose attack, and Sailor Chibi Moon called Pegasus using Crystal Twinkle Bell, and Sailor Moon destroyed Pakupaku with Moon Gorgeous Meditation.
Trivia
