Celestial Instrument

A Celestial Instrument can take any form, and is the main weapon of all Cosmic Warriors.

Overview
Celestial Instruments are the primary weapons of the Cosmic Warriors, each one being specific to the soul of the Warrior they belong to. Its shape, power, and form all depend on the strength and will of its owner. Like with their owners, Celestial Instruments can take on a specific attribute, usually corresponding to their owners' planet. It is unknown how Instruments came into being or how Warriors acquired them, but in the 20th century, a reincarnated Warrior Moon was given her Instrument's avatar state through contact with Luna. The same was shown for Makoto, and can be assumed for Minako.

Celestial Instrument Forms
Depending on the strength of the weilder, the form a Celestial Instrument takes can change.
