Octavia is a tall, slim adolescent avian demon with unkempt slate-gray feathers forming shaggy hair and bangs. She has pink sclera with bright white pupils, a small black beak, and long white pointed fingers. Her tail feathers have slightly darker tips. She bears traits from both parents—her father's white mask-like face and owl-like appearance, and her mother's eyes, eyelashes, and figure. She wears soft-purple eye shadow. As a teenager, Octavia has developed a sharp, sarcastic wit and a cynical outlook, likely due to her chaotic home life. Despite this, she deeply craves her father's love and is sensitive to abandonment, often masking her vulnerability with snark.
