| Sailor Cocoon |
Sailor Guaridan of Cocoon
She is only mentioned in the Materials collection so her appearance is known.
Her Sailor Crystal-grade Star Seed was stolen by the Sailor Animamate-in-question, who wanted to win Sailor Galaxia's favor, hoping to be granted a Sailor Crystal-grade Star Seed, becoming a Sailor Senshi and ruling over a planet of her own.
- The name of the planet Cocoon, and by virtue, the name of the Sailor Senshi, Sailor Cocoon, is mentioned only in the Materials Collection, on the page featuring Heavy Metal Papillon.
