Helioptile is a small, lizard-like Pokémon. It has a tapering tail, short legs, and small feet with three pointed toes on each foot. Its body is pale yellow, while its feet and the tip of its tail are black. The top of its head is black as well with a small triangular yellow patch between the eyes. It has two long, black pointed frills with yellow tips hanging from the sides of its head, which can stiffen and unfold. These frills have cells which generate electricity when exposed to sunlight. It has large eyes with blue irises and white pupils. Helioptile can generate its own energy from sunlight, so it can thrive without food; it will still eat if needed. It lives in deserts.
