Physiology
Gastly's appearance consists of a dark sphere (its "head") surrounded by a light purple gas. Gastly have big, white eyes and a mouth with a pair of fangs in it.

Behavior
Due to having a body made of gas, Gastly can slip into any place it wants.[64] However, Gastly's body will dwindle away when exposed to a strong wind. Because of this, groups of them shall gather under the eaves of houses to prevent being blown away. They are also proficient at sneaking up on unsuspecting prey and putting it to sleep or poisoning it through its skin. As Gastly's body is blown away by wind Gastly live in old, dilapidated buildings, and can also be found at cemeteries.

Special abilities
Gastly have the ability Levitate, which allows it to make all Ground-type moves to miss. Gastly is made of a very thin, gas-like substance, which grants it certain powers and weaknesses. It can sneak into any place if it so wishes thanks to the invasive properties of gas molecules. It can also render itself nearly invisible and approach enemies undetected, and can envelop said enemies regardless of their size.

Evolution
Gastly evolves into Haunter at level 25.
