Haunter

Haunter is a Ghost/Poison-type Pokémon introduced in Generation I, evolving from Gastly at level 25 and evolving further into Gengar when traded. Known for its mischievous and sometimes sinister nature, Haunter is often found in dark, abandoned places like caves, old mansions, and graveyards, where it preys on the fear of others. Its body is composed of gas, allowing it to float through solid objects and sneak up on unsuspecting victims. In the Pokémon games, Haunter is a significant early-game Ghost-type and a fan-favorite due to its unique evolution method and prominent role in the series, including its iconic appearances alongside Ash in the anime. Its playful yet menacing demeanor has made it a memorable character, embodying the spooky charm of the Ghost type. Haunter's signature move, Lick, is known for its paralyzing effects, reflecting its gas-like tongue described in the Pokédex. It holds a special place in the hearts of many trainers as an accessible yet powerful Ghost-type, often serving as a gateway to understanding the complexities of Ghost Pokémon in battle.
