Operator 21O





Operator 21O is a Boss in Nier: Automata


Pronounced "two-one-oh". Calm and skilled at analysis, this operator was originally in charge of relaying messages to 9S. She personally requested to have her equipment transferred to a B-model for the drop, after which she joined the battle as 21B before going missing. She was eventually encountered again at the resource recovery unit in the amusement park ruins, where she had already been overrun by the virus. In the end A2 had no choice but to take her life.
