She has deep brown skin shining with sweat, dark brown eyes and long black hair in tight cornrow braids pulled into a high ponytail, and an athletic, muscular build. She wears a black sports bra, red satin boxing shorts with a gold waistband and black high-top boxing boots. She looks at the camera with a fierce, focused stare. Behind her are red ring ropes, a dark arena with blurred crowd silhouettes and a pair of red gloves hanging on the corner post. A bright spotlight from above makes the sweat on her shoulders glisten, with deep shadows below."
