AK-12

She's one of the best T-Dolls in terms of combat abilities, a fact that she likes to subtly rub on other dolls. Unlike M4A1 post-Singularity, who is cold and standoffish but prone to make emotionally-clouded decisions, AK-12 is typically arrogant but becomes incredibly robotic during combat.

Yes, she smiles almost all the time. No, she is not a warm and kind figure in the vein of, say, Springfield or M1 Garand. AK-12 is a smug and arrogant Doll who regards others as not worthy of her time and comes and goes as she pleases.

It is noted that she has surprisingly short attention span, which contributes to her smug image.

Almost always depicted with her eyes closed. She does this to conserve processing power. Rather than obscuring her sight, her eyelids act more as a "filter" against unnecessary information. She only opens her eyes when the situation gets serious, which as above closes off her emotion and personality modules to focus solely on the current situation.

Shaw's "Wolf's Eye" system gives AK-12 incredible sensory capabilities, being able to perceive and process information far beyond what a standard T-Doll can. This manifests as her magenta irises and weirdly-shaped pupils. AK-12 finds constantly seeing the world like this tiring, however, which is why she closes her eyes most of the time.

Whenever she opens her eyes, her emotion and personality modules are closed in order to divert processing power to more relevant systems. This is reflected in-game with her combat dialogue, which are delivered in matter-of-fact manner.

As one of a small handful of T-Dolls built and geared for maximum combat efficiency, AK-12 has a very low opinion of others, and considers them inferior to her own abilities. Her semi-permanent smile doesn't help matters.

Compared to AK-15, her intended partner, AK-12 can't match her as a physical powerhouse, but compensates with guile and subtlety that make her much more versatile.
