Butterfree is a lepidopteran 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.

The wings of Butterfree are coated with poisonous scales that easily fall off continuously as it flies. If inhaled, it results in several status conditions. It will defend Caterpie from bird Pokémon using this powder. This powder also repels water, enabling it to fly and gather honey even in the rain. Butterfree can use its sensitive antenna to detect the odors of blooming flowers six miles (ten kilometers) from its nest in search of nectar, which it carries with the hairs of its legs. Sometimes, it has territorial disputes with Cutiefly over fields of flowers. It also consumes sap from trees pierced by Heracross, as seen in the anime. Butterfree is found in temperate forests and jungles, but it has also been observed flying near the ocean as part of its migratory breeding pattern.

Forms

Butterfree has a Gigantamax Form.

As Gigantamax Butterfree, its wings become shades of bright and dark green with a white pattern on them. At the base of the wings are a fur-like circle, which attaches to Gigantamax Butterfree's back. Its antennae become bright green as well, and extend to the point where the tip bends, and three red clouds surround them. Its eyes glow bright red. Several green scales, created from crystallized Gigantamax energy, can be seen floating around Gigantamax Butterfree. These are its most effective weapons, capable of causing paralysis, poisoning, or sleep. Gigantamax Butterfree scatters these scales by the winds that it generates with each flap of its wings; these winds are powerful enough to lift a 10-ton truck.

Evolution

Butterfree evolves from Metapod and is the final form of .
