Doll is a Marine Vice Admiral and Commander of the G-14 Marine Base.

Doll is a tall, busty woman with blue eyes, long eyelashes, and short black hair with bangs. She wears a black short-sleeved top with a cleavage and black leather pants with a brown belt and a buckle in the shape of a skull and crossbones. She also wears a spiked choker, hoop earrings, and has small, purple flower tattoos on her arms.

Doll is seemingly not an empathetic person, asking Tashigi to quiet down Helmeppo after his friend Koby had been kidnapped. Doll was also annoyed at Garp for borrowing Navy manpower in an operation to rescue Koby from the Blackbeard Pirates without clearance. Doll however does appear to have a soft spot for children, as she agreed with Vegapunk's request to attach balloons to the Marine Headquarters G-14 Branch to make the Punk Hazard children feel more at ease.

As a Marine, Doll strongly believes in justice, though whether she believes in Moral Justice or Absolute Justice is still unknown. She is strong enough to damage a Mark III Pacifista with a kick.
