|Epsilon and Zeta|
Epsilon was a character who appeared in a side story in the Sailor Moon manga. She and Zeta were personifications of two weaver stars who convinced the third star, Shokujo, that her husband Kengyu did not want to see her because he was only interested in younger and prettier girls. At their prompting, she sold watches with Sailor Moon on them to children in Azabu-Juuban, then summoned the children to Ichinohashi Park while in disguise as Sailor Moon.
Sailor Chibi Moon revealed that the supposed "Sailor Moon" was a fake, but Epsilon and Zeta still prodded Shokujo to take the children's energy, claiming that if they did then she would have more energy of her own. Diana then recognized them as the weaver stars, and Sailor Chibi Moon destroyed them with Pink Sugar Heart Attack.
- Epsilon is the fifth letter of the Greek alphabet, and in astronomy is used to represent the fifth-brightest star in a constellation.
