Doll is a Marine Vice Admiral and the Commander of the G-14 Marine Base. She is a tall, busty woman with blue eyes, long eyelashes, and short black hair with bangs. Her attire includes a black short-sleeved top that reveals her cleavage, black leather pants with a brown belt featuring a skull and crossbones buckle, a spiked choker, hoop earrings, and small purple flower tattoos on her arms.
Doll does not seem to be an empathetic person, as she asked Tashigi to quiet down Helmeppo after his friend Koby was kidnapped. She also expressed annoyance at Garp for using Navy manpower without clearance during an operation to rescue Koby from the Blackbeard Pirates. However, Doll does appear to have a soft spot for children, agreeing with Vegapunk's request to attach balloons to the Marine Headquarters G-14 Branch to help the Punk Hazard children feel more comfortable.
As a Marine, Doll strongly believes in justice, though it remains unclear whether she adheres to Moral Justice or Absolute Justice. She possesses considerable strength, demonstrated by her ability to damage a Mark III Pacifista with a single kick.
