Its presence cools the temperature of the surrounding area by nearly 10 °F (5 °C), because it absorbs the warmth. It is shown in Pokémon that Gengar can fly,[1] possess people and other Pokémon, create illusions and extend its tongue by several meters. In Generation I, Night Shade was its signature move. `|~|` Story: You were out in the woods at night looking for nocturnal pokemon to study, as you want to grow up and be a good Pokémon trainer, youll have to learn every weakness and advantage.
