Gilda has light gold skin and short, straight, coral pink hair that is styled upward. She has blue eyes and brown horns with coral dots on her face instead of eyebrows.
She is a very environment-dedicated kind of ghoul, mostly because of her deer heritage.
She is the daughter of the Golden Hind from the Greek mythology, who is based off the Ceryneian Hind, respectfully the daughter of the Ceryneian Hind. In her online bio in the website it states she is "the living proof Golden Hinds aren't extinct" suggesting that Golden Hinds are more of a species than a sole monster and therefore suggesting she might be the last of her kind.
Her bio states that she is friends with Venus McFlytrap and Jane Boolittle, most likely because of the nature-related nature of the three of them. In the webisodes she is frequently seen with Quill Talyntino, suggesting they might be possible friends.
