Manegin was a Youma who appeared in the musical Sailor Moon - Gaiden Dark Kingdom Fukkatsu Hen, its revision, the Sailor Moon Super Spring Festival, and the video game Sailor Moon for the Mega Drive. Her name was a pun on "マネキン" (Mannequin).
In the musicals, Manegin had the power to inflict a variety of ailments on her enemies, including paralysis, sneezing, hunger, confusion, and pain. She could also summon lesser energy-draining Youma called the Manegin Gundan ("Gundan" (軍団) meaning "army corps").
When Queen Beryl and the Dark Kingdom were revived, Manegin approached Usagi and her friends in the swimsuit section of a department store as Haruna Sakurada. She encouraged them to go to the beach with her on vacation. However, Rei Hino, who detected Haruna's true nature, forced her back into her Youma form. Manegin and her minions attacked Usagi and her friends in an attempt to seize the Silver Crystal, and she used her powers to prevent them from transforming. Luckily, Tuxedo Mask intervened and Manegin and her allies went away. Although Ami, Rei, Makoto, and Minako chased her, she escaped. Some of the Manegin Gundan were later summoned by Beryl to help fight Tuxedo Mask, but Manegin herself did not reappear. It was unclear whether she was actually Haruna transformed into a Youma, or whether she simply disguised herself as the teacher in order to set a trap for the Sailor Senshi.
In the video game, Manegin appeared at the top of a shopping mall as the first boss to be defeated. Among her powers she had super speed and poison breath.
