Poupelin was a fairy recruited by Queen Badiane to collect the children of the world. She told them that she wanted to lead them to a dream world where everyone would be happy, but in reality, she wanted to encase them in Dream Coffins and use their dream energy to power the Black Dream Hole. He seemed to be the leader of the fairies.
When Sailor Uranus destroyed his flute with Space Sword Blaster, he turned into a blue bird and flew away.
- A poupelin is a kind of French pastry.
