Undohkai is a Daimon sent by Mimete to steal Pure Hearts. She has a giant crab shell on her back (as she was created from a shell) and can shoot ribbons that tie people together. She appeared in Episode 28 of Sailor Moon S.
Mimete took Undohkai with her to extract the Pure Heart of an athlete named Shawn Hayes. After sucking out his Pure Heart and eating it, Undohkai attempted to run, but ran into Hotaru, who uses her power to blast her backwards. She was protected by her shell, but Sailor Chibi Moon used Pink Sugar Heart Attack on her, and Sailor Moon transformed into Super Sailor Moon and destroyed her with Rainbow Moon Heart Ache, leaving only the shell and Shawn's Pure Heart.
Trivia
- Undohkai is among the Daimons that appear in Sailor Moon: Another Story.
