"Cocoon" is a planet that existed in the manga.
Its name was given in the Materials Collection as the original home planet of Sailor Heavy Metal Papillon. Following the pattern established for the homeworlds of the other Sailor Animamates, it is likely that the planet's original Sailor Senshi was Sailor Cocoon, and that the planet was devastated during Sailor Galaxia's conquest of the galaxy.
Trivia[]
- A cocoon is a moth's home (caterpillars) until it becomes a real moth.
