Calaveras

Calaveras is the second-oldest of the sisters and has the ability, much like Tuxedo Mask, of communing with spirits of the dead. She uses the energy of her deceased sisters to attack Sailor Venus in the manga whom she fails to kidnap. She is named for the mineral calaverite, and is a counterpart of Minako Aino. She attacks with a whip similar to Venus' Love Me Chain attack, known as the "Dark Love Whip" according to the Sailor Moon R anime album and the Another Story Super Famicom RPG. Calaveras is the only sister in the manga who Rubeus appears to flirt with.

In the manga, she is the last sister to appear, and her mission is "Code:004, Operation Re-birth." She is shown to have the power of channeling, and channels the spirit of Rubeus into Tokyo to brainwash the humans and change their allegiance from the White Moon to the Black Moon and to get them to destroy the Silver Crystal. In the anime, Calaveras is shown to be a petty woman who indulges in relentlessly teasing her other siblings, especially Petz. She also appears unwilling to do anything for herself. She never accepts a single mission and instead tags along on several of Petz' missions and also follows Petz on one occasion to steal credit for Berthier's final mission.
