That's right, I won't give up because I am... A Sailor Soldier.
~ Sailor Cosmos in her first appearance


Sailor Cosmos is the last known form of Sailor Moon in the Sailor Moon manga, she is depicted as being the Sailor Moon of a very distant future, where she reached a stage of being the embodiment of the cosmos.

She fled from her time to take refuge in the time of Sailor Moon because of Sailor Chaos, in order to incite her to destroy the source of everything in the universe and all enemies, the Galaxy Cauldron. This was to prevent Sailor Moon from having to endure all the suffering she has experienced.

Guardian Cosmos is a part of Sailor Cosmos who might've been around at the creation of the universe since she possibly created it.

Sailor Cosmos: In the even further future, Sailor Cosmos, the ultimate form of Sailor Moon, battles Sailor Chaos, the reborn form of her old enemy. In this form, she possesses the Cosmos Crystal itself as her essence, sharing an essence with that of Existence, and emanates the Lambda Power. In this state she can use the powers of every Sailor Senshi, including Sailor Chaos. At this level, Sailor Cosmos no longer needs to cast an incantation or recite an attack name.

Key: Chibi Chibi | Sailor Chibi Chibi Moon | Guardian Cosmos | Sailor Cosmos

Note 1: She doesn't have the abilities of Chaos because even if Sailor Cosmos possesses the powers of the senshi, Chaos possesses the Chaos Crystal, the opposite of the Cosmos Crystal and therefore by logic it can not use it. Also, Cosmos has not been able to defeat Chaos.

Note 2: About the Silver Crystal, declarations that it possesses an infinite, universal and unfathomable energy are true, this has been repeated a dozen times in serious ways, this is therefore not a hyperbole. Also, the Silver Crystal is the center of the Sailor Moon plot. Every villain tries to acquire it.

Note 3: Sailor Cosmos possesses the Silver Crystal, so she can use the powers of any Senshi.
