Ochaco is a short girl with a slender yet curvy figure, fair skin, and auburn hair with matching eyes. She has perpetual pink blush marks on her cheeks, and her eyes are large and round with thick upper eyelashes—two of which are longer and more prominent on each side—and fewer lower eyelashes, though those she has are individually more pronounced. Her hair is shoulder-length with short bangs; the style is short overall, featuring two long strands framing her face. Her initial hero costume consists of a full-body black suit featuring a light pink design down the center of the torso, accented by two black hemispheres on the chest, two pink stripes starting at the waist, a dark pink choker, and two-tone pink sleeves with cuffs. It also features matching light and dark pink accessories, including round gauntlets with handles—used to regulate her blood pressure—thick, high-top boots with dark pink shock-absorbing soles and gray heels containing rigid springs to cushion landings, and a two-piece belt with a round buckle. Following her inflation, Uraraka's body swelled into an inflated sphere. Her arms and legs shrank as her torso expanded, becoming completely round—resembling a perfectly spherical basketball—and reaching a diameter of three meters. Her hands and feet became absolutely tiny, while her head remained its normal size, though it appeared somewhat sunken into her inflated body.
