A Ukrainian game developer & rsearcher who is at least 40. Dr. Juvenile is a blonde woman garbed in a black mini-dress with black fingerless gloves, black thigh-high stockings & black stiletto boots. Her white lab-coat features a flame pattern on the hems & an assortment of colorful badges over the right breast. She wears a stethoscope attached to large headphones around her neck & carries a doctor's bag.

Her heavy, black eye make-up runs constantly as a result of crying. She has a prominent tattoo of an indigenous-styled eagle on her decolletage.

Initially, she appears to be condescending, making furtive jabs at others intelligence. However, accounts of her character by the many people she's interacted with during her career depict a tortured figure, one whose life is characterized by pain & loss.

She has been described as being "complicated" & "hard to explain". Despite this, she seems to enthrall nearly everyone she meets, they often sense how unusual she is.
