Momo is a tall and beautiful teenage girl with waist-length black hair (when let down) that is often styled back in a spiky ponytail with a chin-length hair strand usually hanging on the right side, thin onyx-colored eyes that is accompanied by short eyebrows where it is usually set in a determined expression and she possesses a rather mature physique for her age. Due to her Quirk’s need for fat cells, she prioritized keeping her figure fuller than her peers.
