This is an evolved image of a cybernetic shapeshifter.
The mode / persona of hers that's most associated with metals and things metallic is Sgt. Anatolia Yeltsin, who was programmed with both military and paramilitary protocols plus false memories.
Initially, Polycline-57 had neither a clear agenda nor any sense of ethical morality. To exist & to perform was the extent of it. However, as she gained in self-awareness, skill, and power, she was faced with a physical and psychological no-win scenario.
She chose survival over self-destruction -- but on her terms.
Therefore, she chose to drastically alter who and what she was. As a result, she has a multi-compartmentalized hive mind -- rather than multiple personalities in the traditional sense.
