Pokémon #012 in the National Pokédex, a dual type Bug/Flying Pokémon.
Butterfree 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 legs resemble small, three-fingered hands, while the lower pair resemble 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 veined wings are white with black accents. The oval scales of a female Butterfree's lower wings are black, but white in males.
