Haunter

Haunter, the Gas Pokémon, is a Ghost/Poison-type Pokémon introduced in Generation I. It is the evolved form of Gastly and itself evolves into Gengar when traded. Haunter is known for its mischievous and sometimes sinister nature, often depicted floating silently in the dark, waiting to surprise its victims. Its body is composed of pure gas, allowing it to pass through solid objects and make its presence known through chilling breezes and unsettling whispers. In the Pokémon anime, Haunter famously befriended Ash Ketchum for a short period, showcasing a playful side alongside its spooky demeanor. Its primary habitat is dark, abandoned places like caves, old mansions, and graveyards, where it can easily blend into the shadows. Haunter's predatory behavior involves licking its prey, which causes paralysis, or tapping shoulders with its gaseous hands, leading to endless shuddering. Its Ghost typing gives it immunity to Normal and Fighting moves, while its Poison typing makes it vulnerable to Ground and Psychic attacks. Haunter’s distinctive appearance, with its disembodied hands and menacing grin, has made it a recognizable and popular Pokémon since its debut.
