I think Doll used the wrong upgrade... [MURDER DRONES]

Appearance:

Doll was a female Worker Drone who had long dark indigo hair with blunt bangs and neon red-orange eyes (which glows more red when she's angry). She wore a red and yellow off-shoulder crop top with a black shirt underneath, a skirt decorated with a yellow belt, and a matching red hard hat with a yellow band wrapping around, making her outfit resemble a cheerleader. She also wore tall black winter boots.

Doll is an interpretation of the Quiet One trope — introverted and taciturn.

Doll rarely spoke to anyone, talking occasionally with her best friend, Lizzy, and giving enigmatic non-answers to questions anyone might have. In addition to being quiet, Doll lacked any interest in expressing herself to others under the assumption that no one understands how to help her. When first confronted by Uzi, Uzi tries to talk her into moving on, responding to Uzi's attempt at persuading her by saying she doesn't need help, implying she doesn't choose to listen to anyone.

In contrast to her cold nature however, Doll does appear to have a more lighthearted and immature side that rarely sees the light of day, as she is seen gleefully participating in Lizzy's bullying of Uzi in the PILOT. Beneath her facade of an introvert who prefers to keep to herself are deep psychological problems resulting from seeing her parents killed and eaten at a young age by Serial Designation V. This aftermath resulted in Doll becoming hellbent on killing Serial Designation V as revenge for the deaths of her family as she does anything to achieve her goal, even resorting to murdering some of her fellow Worker Drones. Furthermore, Doll has shown herself to be both determined and deadly, but she has also proven to possess keen perception and quick thinking in challenging circumstances.

Despite being undeniably persistent and murderous, Doll has shown to have a grasp of some morals and sympathy for others. For example, she cares about her fellow Worker Drones, particularly her friendships with Lizzy and Thad. She likes to play board games with Lizzy, and gets really invested in them. She is also known to not get invited to parties and doesn't often interact with many other Worker Drones besides her few friends. Regardless of the fact she doesn't like to express herself, she can relate to anyone who has faced similar situations akin to hers, particularly with Uzi.
