Haunter, called the "Gas Pokémon", appears as a purple, levitating spherical creature, with three spikes extending from each side of its head, angled towards its backside and slightly upward. Its lower back ends in a larger cone-shaped tail, ending in a jagged edge on the sides and of nearly equal length of its body. Its face consists of two white triangular eyes and a wide, pink mouth with jagged teeth that blend into its body. Haunter's body levitates in the air while its sole appendages-two disembodied three-finger hands-hover in the air in front of it. Within the lore of the series, Haunter are described as hiding in very dark places such as graveyards and abandoned caves, stalking their prey. They attack prey by licking them with their tongue, causing paralysis and draining life energy, represented in the games by their "Lick" attack. Haunter can also turn intangible to pass through solid objects, or camouflage themselves as a floating purple orb.
