The influence of Flutter's dragonfly genes is most apparent in the two pairs of transparent wings on his back, the prominent toothed jaw, and his compound eyes, which also sport one pupil each. He has dark, messy hair that protrudes in four directions, vaguely resembling butterfly wings. He wears a loose top with long, baggy sleeves and a Korean collar, a white undershirt with a frayed lower hem, and a long skirt with scale-like decorations over a pair of boots.
