Doll has long dark indigo hair with blunt bangs and neon red eyes. She wears 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 wears tall black winter boots.

Doll rarely spoke to anyone, talking occasionally with her friend Lizzy and giving enigmatic non-answers to questions anyone might have. But deep down, she's very kind.
