Gengar, known as the Shadow Pokémon, is a dark-purple Pokémon with a roundish body. Gengar is the first of its evolutions to have hands and legs connected to its body. Gengar also has a spike-covered back, and its eyes are a sinister red. Its mouth is usually curled into a wicked grin. Gengar steals the heat from the area around it; its presence cools the temperature of the surrounding area by nearly 10 ° F.
