Sailor Quartet

The Sailor Quartet (セーラーカルテット), sometimes referred to by the fanon term Asteroid Senshi, appeared in the manga, musicals, and Crystal. They were four Sailor Senshi who were to awaken as Chibiusa's bodyguards when she took on the role of Sailor Chibi Moon. They represented four of the asteroids in the Solar System's asteroid belt that were at one point in time classified as planets. Their names were Sailor Vesta, Sailor Pallas, Sailor Ceres, and Sailor Juno.

They were prematurely awakened in the Dream arc of the manga by the Dead Moon and recruited as the villainesses CereCere, PallaPalla, JunJun, and VesVes (the Amazoness Quartet). In the manga and Crystal, after the Dead Moon was defeated, their true Senshi forms were revealed. In the anime, the Amazoness Quartet appeared in the Sailor Moon SuperS season but did not become Senshi.
