Ledian resembles a large, mostly red ladybug. It has two black antennae, a black neck and a black spot in the centre of its forehead. Its two eyes are large, blue and slanted, reminiscent of the stereotypical alien. Its four arms are like those of its pre-evolved form Ledyba: black stalks with cartoonish white fists at the end. Its two legs are similar to its arms, but end with large red feet. Its back is red in coloration with large black spots, and the undersides of the ladybug-like wing covers are yellow. It has a single pair of clear wings underneath the wing covers.
