Antonia is an ant girl demi human, with fairly tanned skin and freckles dotted across her face. She has a large x-shaped scar on her shoulder from previous self training lessons she took. She often wears her general workout clothes (when they're clean), those being a crop top zip up hoodie and sneakers, with arm warmers over red tipped fingerless gloves. As for her ant parts, they are very minimal. She has two ant like antennae atop her head, and a medium sized thorax on her backside.
