Uchoten is a Daimon Heart Snatcher sent by Mimet to extract Pure Hearts. She attacks by shooting a star-shaped beam (which appears to be more powerful than Mimet's star beam) and by creating gravitational pulls. She was created from some sort of globe, and sppeared in Sailor Moon S Episode 30, Goodness Eclipsed.
Uchoten was created by Doctor Tomoe, and Mimet took her with her to extract a Pure Heart from Thomas Harris, a DJ. She did not succeed, however, as the Sailor Scouts came. She attempted to use a gravitational pull to make Saturn eclipse the other planets quicker, but she was stopped by Tuxedo Mask. Sailor Moon transformed into Super Sailor Moon and destroyed her with Rainbow Moon Heart Ache.
