Gengar is a Ghost/Poison-type Pokémon introduced in Generation I. It is known for its mischievous and playful nature, often lurking in shadows and playing tricks on unsuspecting trainers. Gengar has a round body, a wide grin, and pointed ears, making it easily recognizable among other Pokémon. In battles, Gengar is known for its high Special Attack and Speed stats, allowing it to deal significant damage quickly. It can learn a variety of moves, including Shadow Ball and Sludge Bomb, which take advantage of its Ghost and Poison typing. Gengar evolves from Haunter when traded, and it is the final form of Gastly.
