92. Gastly

Japanese Name: Ghos

Gas Pokémon

Gastly has no true form, due to 95% of its body being poisonous gas. However, it consistently appears as a black, spherical Pokémon surrounded by a purple haze. It has a wide, pink mouth with two visible fangs. Though its eyes seem to extend past its round body, visible eyelids surround them. It produces a faint, sweet smell. The toxic gas surrounding the main body can induce fainting and suffocation, and it is capable of enshrouding an enemy of any size. Its gaseous form makes it one of the lightest Pokémon tying with Haunter, Flabébé, Cosmog, and Kartana.
