9S (full designation YoRHa No. 9 Type S (Scanner)) is a recurring guest character in the Final Fantasy series. Typically issued alongside fellow YoRHa unit 2B, 9S is the deuteragonist of the 2017 Square Enix hybrid RPG NieR:Automata.

Created by the same project that produced 2B, 9S is a scanner unit participating in the proxy war between humans and alien assailants that takes place in 11945 CE. From the space base known as the Bunker, 9S is initially assigned to provide support for 2B. His true motivation, however, is kept secret, even as the bond between the pair develops over the course of the source story.

9S is an accomplished hacker, using his skills to analyze his opponents as well as to disable and destroy their armaments.



Though an android, 9S appears built as a slender young man in his twenties. Like other YoRHa models, he has silvery-white hair, with his in a bowl or mop cut. A standard-issue combat visor conceals his light blue eyes, and he wears a dark uniform resembling combat fatigues.

Behind the scenes[]

9S's short-form designnation may have been chosen to complete 2B's references to Shakespeare's Hamlet, as it is believed to play on the Latin non esse, meaning "not to be".
