Butterfree is an insect Pokémon which resembles a vaguely anthropomorphic butterfly with a purple body. Unlike true insects, it only has two body segments and four light blue legs. The upper pair of its legs resemble small, three-fingered hands, while the lower pair resembles long, digit-less feet. Butterfree has two black antennae, a light blue snout with two fangs underneath, and large, red compound eyes. Its two pairs of wings are white with black venation. Two oval scales on a female Butterfree's lower wings are black, but they are white on a male.
