Cocoon

Cocoon was a planet that existed in the Sailor Moon 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 other homeworlds of the 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.
