- "Try and outrun five rings of hatred at once!"
- —Regalia, Ep. #70
Regalia is a droid sent by Emerald to fill a vulnerable spot in Tokyo with dark energy. She attacks by throwing energy rings at her enemies that can make them suffer their worst nightmares, feel isolated from the world, or make friends hate each other. She appeared in Sailor Moon R Episode 30, Promises Fulfilled.
The vulnerable spot Emerald attacked was a bracelet shop, where people were making love bracelets. Regalia disguised herself as the teacher there, and charged the bracelets with dark energy so that whoever wears them will be contaminated with dark energy until the city is full of dark energy. When Rini put Serena's love bracelet on, Serena realized what was going on, so she and the others transformed into the Sailor Scouts to fight Regalia. Every time Regalia tried to use one of her evil rings at Sailor Moon, Tuxedo Mask and the other Sailor Scouts would arrive and stop her. In the end, Sailor Moon destroyed Regalia with her scepter (saying "Activation" instead of "Elimination").
- Regalia's hatred rings look identical to the Olympic rings, minus the color.
