On her left bicep, she wears a yellow armband marked with a skull emblem, signifying her role and identity as a Disassembly Drone. When in combat mode, she reveals jagged teeth, and her visor displays an "X" shape, signaling her aggressive intent.

She also has a black choker around her neck with a skull and the number "002" on it.Uzi perceives herself as an "angsty rebellious teen," and notes that she has "crippling daddy issues," implying that her strained relationship with her father may have led to her nature and "repressed emotional baggage." She can be obstinate at times, insisting on her ideals and actions even if others disagree with her, although this may more directly be a result of her lack of caring in social norms and potentially sociopathic traits making her lack empathy for her peers. Despite her emotional issues, Uzi's intelligence seems above that of her fellow workers, seeing as she built a railgun that can produce enough power to destroy a Disassembly Drone from scratch.
