Haunter is a purple Pokémon with a gaseous body. It has a round head flanked by three large, spiked protrusions on either side. It has triangular eyes with small pupils and a mouth with a long, pink tongue. The gases composing its head curve into its mouth to form several pointed teeth. Disembodied hands with three clawed fingers each float in front of its body. Its body tapers into a jagged tail. Haunter's gaseous form makes it one of the lightest Pokémon in existence.
Haunter hides in very dark places, such as caves, and is afraid of light. If a human or a Pokémon comes near Haunter, it will stalk the victim while floating and beckon it to come closer. Once approached it will then lick the victim with its gaseous tongue, inflicting convulsions in the victim that last until death. It can also float through walls. It has been shown in the anime that it can control its hands from far away and can control any Pokémon that it touches with its hands. Despite its predatory nature, it has been known to entertain and prank people in the anime. Additionally, it has even been shown to feel intense loyalty to a deceased Trainer. In Generation I, Night Shade was its signature move.

With the combined efforts of Ash and the team of hunters, the Black Fog was weakened enough for capture, only for it to promptly use Self-Destruct, killing itself right before Ash's Ultra Ball could reach it.

Origin
Haunter appears to be based on a generic sort of cartoonish ghost. Like Gengar, Haunter may also be based on the Cheshire Cat, as it possesses what may be pointed ears; a large, toothy grin; and the ability to vanish at will. While many Japanese yōkai - ghosts and ghouls - are depicted with long tongues, Haunter's vampiric licking may have come specifically from the Dila, a Philippine spirit that licked the life energy of sick people until they died.
Name origin
Haunter may be derived from haunt and the agentive suffix-er or possibly hunter.
