Gender-bending character in Bishoujo Senshi Sailor Moon, one of the Outer Senshi. In her civilian form as Ten'ou Haruka, she appears as a boyish-looking girl dressed in men's clothes (and was mistaken for a boy by Usagi and Minako). Her main attack is "World Shaking". Tempermental and aggressive, she enjoys flirting with Sailor Moon but is in a relationship with Sailor Neptune.

First appeared in Sailor Moon S where she and Neptune came in conflict with the Inner Senshi while searching for the three mystical talismans. In the manga she can actually change her gender, switching back and forth between male and female as desired.
